How many parameters are needed to know when operating equipment
Thread Content
When learning about various equipment, one often encounters many parameters that need to be memorized. In particular, each type of operating equipment has numerous parameters such as temperature and pressure. So, which specific parameters should be known and remembered? I would appreciate detailed guidance from those with experience. For pumps (especially high-pressure pumps) and compressors (centrifugal, reciprocating), the parameters that need to be kept in mind include things like the lubrication oil temperature of the compressor and pump, as well as the vibration and displacement of centrifugal compressors……
It’s strange; I wonder what the original poster thinks needs to be remembered? It’s usually just the list of measurement points for the relevant pumps and machines on the DCS and FSC systems! ~
The operation inspection record form for running equipment lists the parameters that need to be checked and recorded; the normal values for these parameters are specified in the equipment operation instructions, and they are the parameters that need to be known
It’s already the fifth grade – one should be quite proficient by now, haha. The parameters vary depending on the size of the device, but the differences aren’t very large. It’s not realistic to expect to remember them all completely. In chemical engineering machinery, the four key parameters of a fluid seem to be: pressure, temperature, liquid level, and flow rate. You can take a look :)
Parameters of centrifugal compressors: 1. Inlet and outlet pressures, flow rates, and temperatures; 2. Speed of the unit, vibration of the support bearings, and position of the thrust shaft; 3. Temperature of the lubricating oil tank, temperature at the bearing inlets, temperature of the oil returning to the bearings, pressure in the bearing manifolds, pressure of the oil pump, and pressure difference across the lubricating oil filter; 4. Liquid level in the inlet and outlet separators of the compressor; 5. Temperature of the compressed air after cooling.
Parameters of reciprocating compressors: 1. Inlet and outlet temperatures and pressures; 2. Pressure and temperature of the compressor’s lubricating oil, as well as the pressure difference across the filter; 3. Temperature control of the compressor’s lubricating oil heater; 4. Temperature after air cooling; 5. Liquid level in the compressor’s inlet separator
Parameters of reciprocating compressors: 1. Inlet and outlet temperatures and pressures; 2. Pressure and temperature of the compressor’s lubricating oil, as well as the pressure difference across the filter; 3. Temperature control of the compressor’s lubricating oil heater; 4. Temperature after air cooling; 5. Liquid level in the compressor’s inlet separator
Operating parameters of the centrifugal compressor unit: 1. Inlet and outlet pressures, flow rates, and temperatures of the centrifugal compressor and the turbine； 2. The speed of the unit, the vibration levels and temperature of the support bearings, and the displacement of the drive shaft ； 3. Gas sealing system: pressure, pressure difference, flow rate of buffer gas, isolation gas, and sealing gas, as well as the pressure of the exhaust gas ； ⒋Lubricating oil and seal oil systems: tank temperature, tank level, temperature after water cooling, bearing inlet temperature, bearing return oil temperature, bearing manifold pressure, oil pump outlet pressure, lubricating oil filter pressure drop, control oil pressure, main lubricating oil pipeline pressure, levels of the two high-level oil tanks ； 5. Compressor inlet separator level. Wait, parameters of the reciprocating compressor: 1. Temperature, pressure, and flow rate at the inlet and outlet ； 2. Pressures, temperatures, and filter pressure differences in various parts of the compressor lubricating oil system ； 3. Motor stator temperature, bearing temperature, temperature before and after cooling by cooling water, liquid level of the level gauge switch ； 4. Compressor inlet separator and interstage tank liquid levels ； 5. Horizontal and vertical vibration values of various parts of the compressor and motor. Parameters recorded by the pump ； ⒈Pump inlet and outlet pressure ； ⒉Horizontal and vertical vibration values of the bearing ； ⒊Motor current ； ⒋Total running time ； There’s a lot more; study hard!
For different types of work, the parameters that need to be known vary: 1. Workers who are solely responsible for operation (field workers) should focus on on-site parameters such as motor current, outlet pressure, flow rate, on-site temperature readings, vibration levels, and temperature. 2. Control room operators should pay attention to DCS-related parameters such as motor current, flow rate, medium temperature, and pressure. 3. Equipment managers should remember the manufacturer of the pumps (to facilitate the purchase of spare parts), as well as the motor power, model of the pumps, their flow rate and head, as well as the process parameters related to the medium. 4. Supervisors in charge of equipment should have an understanding of the above-mentioned information, in addition to being aware of vulnerable spare parts, maintenance schedules, methods for diagnosing faults, and trends in equipment renewal.
