Basic surface treatment procedures and methods 4.4.2.1 Basic surface treatment procedure 4.4.2.2 Creating a rough surface on the surface of the base secondary grouting layer ； The pitting depth should be greater than 10 mm, with a density of 3 to 5 pits per square decimeter; moreover, the foundation surface must not have any loose layers or oil stains ； (During work, care should be taken to protect the baseline of the unit foundation to facilitate redrawing it.) ； 4.4.2.3 Excavate a grouting pit at the position corresponding to the machine’s jacks or adjustment shims on the foundation; remove any debris from within the pit. After soaking it in water for about 30 minutes, drain the water from the pit. Fill the pit with grout of a higher grade than that used for the foundation grout, place the support pads in place, and level them using a level. The allowable tolerance is 2 mm/m; the allowable tolerance for the elevation of the top surface of the support pads is ±5 mm, as shown in Figure 2. 4.4.2.4 Recalibration of the installation reference line on the foundation: Before installing the embedded support pads, debris and oil stains on the foundation surface should be removed. The longitudinal and transverse center lines as well as the center lines of the foot bolts should be marked with ink lines, and the elevation levels should be indicated on the sides of the foundation using red triangles. 4.4.2.5 The support shims of the steam turbine are arranged according to the structure of the machine base and the number of anchor bolt holes ； Moreover, no more than four shims are allowed per group; the thicker ones are placed at the bottom, the thinner ones on top, and the thinnest one in the middle. The total height shall not exceed that of the secondary grouting layer. One pair of inclined shims is permitted per group, and the offset area between the two inclined shims shall not exceed 25% of the area of those shims ； The material of the support pad is Q235 steel, with specifications of 160×100 —δ=16. 4.4.3 Treatment of anchor bolts and anchor plates: Oil, rust, and other contaminants on the shafts of the anchor plates and anchor bolts should be removed. Subsequently, the shaft parts should be protected against corrosion; if the instructions do not specify otherwise, apply anti-rust paint to the shaft parts twice, and apply grease to the threaded parts. Treat the contact area with the anchor plate to ensure that the horizontal deviation is no more than 2 mm/m. 4.5 Installation of the compressor unit 4.5.1 Lifting, positioning, and alignment of the unit 4.5.1.1 The turbine is designated as the reference machine for the compressor unit; during installation, the lower casing of the turbine should first be positioned and fixed, after which the other machines are adjusted and fixed using its axis as a reference ； 4.5.1.2 Before lifting, clean the lower surface of the machine base. Use a punch to mark the longitudinal and transverse center lines of the machine body at the edges of the base. Adjust the elevation of the shims and place them on the foundation as required. Lubricate the set screws and thread them out about 10 mm above the surface of the base. 4.5.1.3 Slowly lift the machine base into place so that the vertical and horizontal centerlines on the base align with the centerline on the foundation. Use shovels and jacks positioned around the unit to adjust the center position, and use the prepared shims and base set screws to adjust the elevation ； 4.5.1.4 Lift each machine into place, and use a strip level to check the longitudinal and transverse levelness of the machine body on the specially prepared surface provided by the manufacturer; the overall deviation should meet the following requirements: (1) The center line of the machine unit should coincide with the center line of the foundation, with a deviation not exceeding 5 mm ； (2) The installation elevation deviation of the reference machine should not exceed 3 mm ； (3) The allowable deviation in longitudinal levelness at the installation reference point of the reference machine should be 0.02~0.05 mm/m; for other machines, it is necessary to ensure compliance with the coupling alignment requirements ； (4) The deviation in the lateral levelness of the unit should not exceed 0.10 mm/m, and the levelness of corresponding points on the same machine should be essentially consistent ； 4.5.1.5 Once alignment is complete, tighten the foot bolts and carry out one grouting operation. (1) Make a temporary formwork around each base plate ⑸ and its anchor bolts ⑶. These templates must be firmly fixed to prevent mortar from escaping. Leave at least 100 mm of space between the inner wall of the template and the edge of the footplate. (2) As shown in Figure 3, fill the bolt holes and formwork with grouting material. To prevent bubbles from forming, the mortar must be stirred. (3) When it is confirmed that the mortar has reached the required firmness (2–3 days after grouting, but not exceeding 8–10 days, depending on local atmospheric conditions), the adjustment bolts (2) should be loosened symmetrically. (See Figure 3). (4) After the mortar has dried (depending on the temperature). In summer, it usually takes 8 days to remove the adjustment bolts ⑷ and symmetrically tighten the foot bolts ⑶. (5) Recheck the leveling. Use the adjustment bolts to adjust the shims between the base plate and the footplate ⑸ for final calibration. (6) The final alignment of the unit shall be carried out in accordance with the procedures described in 4.5.3 and 4.5.5. 4.5.5. Aligning the units concentrically (1) Alignment: Use a dial indicator to initially determine the concentrality of each machine with respect to the turbine; adjust it using the set screws on the base. The alignment values should meet those specified in the manual, and after alignment is complete, tighten the foundation bolts. 4.5.6. Secondary grouting of the unit: 4.5.6.1 Use non-shrinkage cement for the secondary grouting layer; a fitter should be present during the grouting process, and excessive vibration must be avoided to prevent displacement of the unit. 4.5.6.2 Before performing the initial secondary grouting, check and re-measure the following items and keep records: (1) The alignment deviation of the couplings and the axial distance between their end faces must meet the specified requirements ； (2) Re-measure the clearance values of the sliding pins, vertical pins, cat claws, and connecting bolts in various parts of the unit ； (3) Check whether all foundation bolts are tightened as required ； (4) If shims are used for installation, after the inter-layer tack welding is completed and the unit passes re-inspection, grouting must be carried out within 24 hours; otherwise, re-inspection shall be conducted again. (5) Before the second grouting, remove any oil stains from the surface of the foundation, rinse it thoroughly with water and keep it moist for more than 12 hours; remove any water on the surface during grouting. 4.5.6.3 During grouting, the ambient temperature should be maintained above 5°C ； The pouring must be completed in one go, and compaction should be carried out continuously during grouting to ensure that the concrete fills all areas tightly. 4.5.6.4. After secondary grouting, proper curing must be carried out; when the ambient temperature is below 5°C during the curing period, anti-freezing measures should be taken. 4.6. Installation of the ammonia compressor unit (aligning the booster and gearbox with reference to the turbine and ammonia compressor) 4.6.1. Lifting and positioning of the various machines in the unit: Clean the lower surfaces of the bases of the turbine, ammonia compressor, and gearbox. Use a marker to mark the longitudinal and transverse centerlines on the edges of the bases. Lubricate the set screws and screw them out by 10 mm, then lift the bases of the turbine, ammonia compressor, and gearbox into place (if they share a common base, lift them as a single unit). Ensure that the longitudinal and transverse centerlines on the bases align with the centerline on the foundation. Measure the distance between the shaft ends, and use jacks positioned around the unit to adjust their elevation ； A strip level is used to check the vertical and horizontal alignment at the bases of the turbine, ammonia compressor, and gearbox; the alignment is adjusted using the set screws on the bases, and once aligned, the foundation bolts of the bases are tightened. The overall deviation shall meet the following requirements: (1) The center line of the unit shall be aligned with the center line of the foundation, and the deviation shall not exceed 5 mm ； (2) The installation elevation deviation of the reference machine should not exceed 3 mm ； (3) The allowable deviation for the longitudinal levelness at the installation reference point of the reference machine should be 0.02~0.05 mm/m; other machines must meet the coupling alignment requirements ； (4) The deviation in the lateral levelness of the unit should not exceed 0.10 mm/m, and the levelness of corresponding points on the same machine should be essentially consistent ； 4.6.2 Initial alignment of the turbine and ammonia compressor: Lift the turbine and ammonia compressor into place, measure the vertical and horizontal levels of the units, and use the set screws on the base to make adjustments; once aligned, tighten the foundation bolts. 4.6.3 Secondary alignment of the turbine and ammonia compressor: A level is used at the shaft journals to check for longitudinal levelness; thin shims are employed at the support points of the turbine and ammonia compressor to adjust the vertical position of the compressor. Horizontal adjustment screws at the support points are used to fine-tune the horizontal alignment of the turbine and ammonia compressor, so that their concentricity and levelness meet the requirements for the final alignment of the entire unit. 4.6.4 After the second alignment, formally tighten the bolts at the feet and the lateral adjustment bolts and lock them, then close the upper bearing cover. 4.6.5 Alignment of the booster, gearbox, and turbine for concentricity (2) Fine alignment: Thin shims with a thickness of 0.02–4 mm are inserted between the supports of the booster and gearbox and the steel base in order to make adjustments, so that the requirements of the unit’s alignment curve in the cold state are met. The alignment values must conform to those specified in the manual; once alignment is complete, the foundation bolts of the unit should be tightened properly. 4.6.6 Shaft alignment of the unit: 4.6.6.1 The shaft alignment of the unit should be carried out after the upper and lower parts are assembled but before secondary grouting is performed. During alignment, make the adjustment using the cold-state alignment requirements provided by the manufacturer. 4.6.6.2 For the cold alignment of the unit, the three-gauge alignment method is recommended. During alignment, shaft alignment is adjusted using the already fixed turbine as a reference. Use the adjustment shims under the machine base to make the final fine adjustment to the compressor’s vertical height. Adjust the horizontal position using the lateral adjustment screw at the support. When adjusting the support shims, first support the compressor’s flexible supports with jacks, then loosen the bolts that hold the fixed support ends in place. Use the adjustment screws on the supports to lift the compressor in order to make the necessary adjustments to the shims. After making the adjustments, loosen the adjustment screws. To ensure that there is no movement in the horizontal direction, use a dial indicator to monitor the left and right supports during the adjustment process. 4.6.6.3 The shaft alignment of the unit shall meet the requirements specified in the technical documents, with an allowable deviation of generally ±0.02 mm. 4.6.6.4 When the compressor and turbine are finally aligned, fix the casing at the same time, and tighten the support bolts symmetrically and evenly one by one. When tightening the support bolts, check the shaft alignment at regular intervals; after the support bolts are tightened, recheck the shaft alignment (it should fully meet the requirements for alignment in the cold state). 4.6.6.5 When assembling the spacer sleeves of the coupling, they should correspond to the positioning marks of the coupling, and the connection bolts should match the marks on the bolt holes of the coupling. After assembly, a clearance should be left in the axial direction as specified in the technical documents; the allowable deviation is +20 mm. 4.6.7 Grouting of the unit (see section 4.5.6 of this document for details). 4.7. Treatment of the bearing housings, oil tanks, oil coolers, and oil filter elements of the compressor unit. 4.7.1 First, check the protective paint on the housings; any paint of poor quality must be removed completely ； Do not remove the top layer of the tank, as this will cause rusting due to the lack of oil exposure; however, any peeling paint on the top layer should be removed. After that, clean the tank with kerosene or gasoline, then wipe it clean with flour. Seal the entrance, take out the oil filter element and store it properly, and replace it in the filter with a temporary filter screen with a mesh size of 120–200. If the oil cooler core is severely rusted, it should first be degreased using carbon tetrachloride or trichloroethylene, and then immersed repeatedly in kerosene or gasoline until a metallic luster appears. After the oil cooler has been cleaned and found to be satisfactory, the water chamber is tested with water and finds to be satisfactory; the oil chamber is tested with oil and finds to be satisfactory. After that, it is reinstalled along with the valve components. 4.9. Unit pin positioning: 4.9.1 After the machine is aligned, fix the machine’s leg shims to the supports. 4.9.2 Adjust the clearance of the coupling bolts according to the clearance specified in the installation diagram or instructions. 4.9.5 Grind the positioning keys according to the clearance indicated in the base diagram (the total clearance should be 0.02~0.12 mm), and finally weld the positioning keys as well as the gasket plates of the positioning groove plates firmly to the base. 4.10. Stress-free piping for the unit: After the couplings of the machine have been aligned, the pipes connecting to the unit should have their fixing welds located away from the unit. The length of the straight sections at the unit’s inlet and outlet should meet the requirements specified in the drawings. Additionally, appropriate pipe supports and hangers should be used to ensure that the unit does not experience any external forces. The maximum torque of the coupling bolts at each flange of the unit must not exceed the values specified in the manual. During piping installation, a fitter shall use a dial indicator to monitor the concentricity at each coupling of the machines, ensuring that it remains within the range specified in the manual or relevant standards. The dial indicator should also be placed in a convenient location on the foundation, or on a structure that is not connected to the machine, with the probe of the micrometer pressed against the machine housing. The allowable deviations for flange connections are as shown in the table below: Rotational speed (r/min), Flange surface parallelism (mm), Radial displacement – 3000–6000: ≤0.15, ≤0.50; >6000: ≤0.10, ≤0.20. 5. Quality assurance measures: 5.1 Organize the construction crew to study carefully the drawings, regulations, standards, domestic and international standards, instructions, as well as construction procedures and methods, in order to ensure the quality of unit installation. 5.2 Strictly control the “five key stages”: drawing review, preparation of construction plans, inspection of raw materials and equipment, quality inspection of construction processes, and quality assurance for the completion deadline, so that the quality responsibility system is implemented in all departments throughout the entire construction process. 5.3 On-site, dedicated quality inspectors are assigned to oversee quality control throughout the entire installation process of the unit, ensuring strict adherence to quality standards; work from one stage shall not proceed to the next if it does not meet the required quality criteria. 5.5 Supervise the work team to carry out construction strictly in accordance with the instructions, construction plans, drawings, as well as relevant regulations and standards. 5.6 Argon arc welding shall be used for all pipes in the unit’s oil system to improve cleanliness inside the pipes and reduce the oil circulation time. 5.7 Use strength-stable, non-shrinking cement paste to grout the compressor base in order to ensure the quality of the grouting. 5.8 Quality control points for compressor installation Sequence Number Inspection Item Inspection Level Sequence Number Inspection Item Inspection Level 1 Inspection of equipment and material handover AR 8 Internal cleanliness A 2 Inspection of equipment foundation handover BR 9 Rotating the machine to check its condition C 3 Grouting of the anchor bolt holes AR 10 Monitoring of foundation settlement CR 4 Alignment of the equipment AR 5 Secondary grouting B 6 Gaps after disassembly, inspection, and reinstallation BR 7 Alignment of the coupling: before and after piping AR 6 Safety and technical measures 5.1 Before installation, safety and technical instructions should be provided to all personnel involved in the construction; these workers must be familiar with the installation procedures, operating guidelines, precautions, and emergency response measures. 5.2 Construction workers must wear safety helmets when entering the site, and safety belts must be worn when working at heights; it is strictly prohibited to work while under the influence of alcohol. 5.4 Safety assurance system (see next page) 7 Emergency response plan: In the event of an accident at the site, personnel should be immediately mobilized to carry out rescue efforts, and 120 should be called promptly.
