Precautions for using chemical process centrifugal pumps
Thread Content
Only by understanding the precautions for using chemical centrifugal pumps can their efficiency be maximized. Therefore, the editor at JieKai has compiled a list of the key points to keep in mind when using such pumps; it is recommended that everyone save this information! 1. Construct the concrete foundation according to the basic dimensions, and embed the anchor bolts for the chemical centrifugal pump at the same time. 2. Place the entire chemical centrifugal pump on the foundation; insert shock-absorbing blocks between the base plate and the foundation. By adjusting these shock-absorbing blocks, adjust the level of the chemical centrifugal pump. After adjustment, tighten the anchor bolts. Before the equipment, the chemical centrifugal pump and motor should be inspected; each component must be in good condition, and there should be no debris inside the chemical centrifugal pump. 3. To prevent debris from entering the chemical centrifugal pump, a filter should be installed at the inlet, with a filtering area that is 3 to 4 times larger than the cross-sectional area of the pipeline. 4. It is also necessary to install a check valve on the outlet pipeline of the chemical centrifugal pump to prevent damage caused by water hammer resulting from sudden shutdown. Both the inlet and outlet pipelines of chemical centrifugal pumps should be equipped with supports; the pump itself cannot be used to bear the loads. The diameter of the inlet and outlet pipes should match that of the inlet and outlet ports of the chemical centrifugal pump. 5. When the viscosity of the liquid pumped by chemical centrifugal pumps is too high, both the performance and efficiency of the pumps will change; for detailed information, please contact us. Magnetic chemical centrifugal pumps cannot pump liquids containing particles or those that tend to crystallize; they must not operate continuously with a closed discharge outlet, and a low flow rate should be maintained. 6. When the liquid temperature is high, it is necessary to implement cooling measures for the mechanical seal of chemical centrifugal pumps in order to prevent the seal from deforming and the static ring from cracking. Once the chemical pump is assembled, manually rotate the coupling to check for any signs of scraping; if it rotates smoothly and evenly, then the assembly is complete.
1. Before operation, carefully read the user instructions for this device, become familiar with its operating methods and requirements, and use it correctly in accordance with the instructions； 2. Centrifugal pumps require good sealing; before each start-up, the pump head should be opened and the bolts tightened to ensure proper sealing ； 3. Before starting, pay attention to adjusting the appropriate speed to maintain stable operation ； 4. Normal forward or reverse operation is a prerequisite for using the equipment after it has been installed ； 5. The equipment should be equipped with a pneumatic adjustment device to accommodate different conveying media ； 6. When disassembling or assembling the equipment, the centrifugal pump must be largely taken apart to avoid damaging the equipment ； 7. The fasteners on the head must be checked regularly to prevent leaks caused by damaged bolts ； 8. Before using the pump, check its interior; do not start the pump if there are any suspected debris or components that could cause damage ； 9. During use, regularly check whether the mechanical sealing equipment is functioning properly, and replenish the lubricating oil in a timely manner ； 10. Install balance rods and silencers to prevent imbalance and noise caused by the centrifugal pump ； 11. Do not install a isolation valve in front of the pump, nor a make-up coupling circuit breaker at the pump’s water inlet ； 12. The pump outlet and the pump inlet cannot be oriented in the same direction ； 13. In the event of an accident in the pipeline, the pump must be turned off immediately ； 14. Turn off the power supply after debugging is complete ； 15. It is recommended to clean and maintain the equipment after each use ； 16. Foot pads should be used under and above the centrifugal pump during installation, and it must be placed firmly ； 17. Maintain a certain gap between the centrifugal pump and the cylinder body to reduce friction noise.
