IMO screw pump It is a common positive displacement pump. Common failures include leakage, noise, unstable pump pressure, etc. The troubleshooting methods for these common faults are described in detail below.
1、 Leakage fault: leakage is generally caused by poor sealing, mainly including the following reasons and troubleshooting methods:
Poor sealing of front and rear covers: the leakage point is at the front and rear covers of the pump, which may be caused by the damage of the sealing gasket, the filter does not work or is not fastened. Check and replace the sealing gasket, ensure that the filter works normally, and fasten the front and rear cover.
Poor seal of shaft seal: the leakage point is at the shaft seal, which may be caused by damaged shaft seal, poor lubrication or high pressure. Check and replace the shaft seal, ensure the lubrication is normal, and control the pump pressure within the appropriate range.
Poor cooling of shaft seal: the leakage point is at the shaft seal, which may be caused by cooling system failure. Check the cooling system to ensure that the coolant circulates normally and the temperature is appropriate.
2、 Noise fault: the noise of the pump may be caused by the following reasons, which will be introduced separately below. IMO agent
Improper pump assembly: the noise source may be caused by the pump assembly problem. Check the pump assembly to ensure that all parts are fastened without looseness and the fit clearance is appropriate.
Ambient noise near the pump: the noise may come from the surrounding environment of the pump. Check the surrounding environment, such as nearby mechanical equipment or vibration sources. COLFAX agent
Hydraulic noise: The noise may be caused by hydraulic system problems. Check the hydraulic system, such as high pressure, loose pipeline, etc.
3、 Unstable pump pressure fault: unstable pump pressure may be caused by the following reasons, which will be described in detail below.
The inlet pressure of the pump is unstable: check the inlet pipeline to ensure that there is no leakage, the valve switch is normal, and the inlet pipeline is clean and unblocked.
Unstable discharge pressure of the pump: check the discharge pipeline to ensure that it is free of blockage, the valve switch is normal, and the discharge pipeline is clean and unblocked. CIRCOR SECCO
Internal pump failure: the pressure may be unstable due to wear and blockage of internal pump components. Check and clean the internal parts of the pump, and replace the worn parts.
That's it Screw pump Introduction to common faults and troubleshooting methods. In actual use, inspection and troubleshooting should also be carried out according to the specific situation to ensure the normal operation of the screw pump.
