Cip Reflux Pump Failure And Solutions

CIP Return Pump is the inlet and outlet water section and the middle section, which are combined together by a pull rod. Its output water pressure can be very high. It is a kind of centrifugal pump, and it also relies on the rotation of the impeller to obtain centrifugal force, thereby material. When the gas density reaches the working range of the mechanical vacuum pump, it is extracted, and high vacuum is gradually obtained. The CIP reflux pump relies on the change of the pump chamber volume to achieve suction, compression and exhaust, so it is a centrifugal pump with variable volume.

Fault 1: The water pump does not absorb water, and the pressure gauge and vacuum gauge pointers jump violently
Reason: 1. Insufficient water injection 2. Leakage at the connection between the pipeline and the instrument 3. The suction range is too high
Solution: 1. Check whether the bottom valve is leaking. Then hire enough water 2. Tighten the leak 3. Reduce the water suction height

Fault 2: The water pump does not absorb water, and the vacuum gauge indicates a high vacuum
Reason: 1. The bottom valve is not open or blocked 2. The water suction pipeline resistance is too large 3. The filter is blocked
Solution: 1. Check the bottom valve 2. Replace the water 3. Clean the filter

Fault 3: The pressure gauge has pressure but still does not discharge water
Reason: 1. The resistance of the water outlet pipe is too large 2. The rotation direction is wrong 3. The outlet pipe valve is not open 4. The impeller is blocked
Solution: 1. Check or shorten the water pipe 2. Check the motor. Adjust the two 3. Open the outlet valve 4. Clear the dirt in the impeller

Fault 4: The design flow rate cannot be reached
Reason: 1. Air is sucked in 2. Due to the lowering of water level, the submergence depth is not enough 3. There are foreign objects blocking the impeller 4. The rotor is seriously worn
Solution: 1. Check the leaking part and eliminate it 2. Extend the suction pipe and deepen the submergence depth 3. Disassemble and remove foreign objects 4. Replace the sealing ring

Fault 5: The pump consumes too much power
Reason: 1. The packing is pressed too tightly and generates heat 2. The flow is too large 3. The rotor and the shell are rubbed 4. The pump bearing is worn 5. The pump shaft is bent
Solution: 1. Appropriately relax the packing pressure 2. Close the gate valve opening 3. Adjust the position of the rotor and the shell 4. Replace the bearing 5. Replace or correct

Fault 6: Increased pump vibration
Reason: 1. Partial blockage of the impeller 2. Impeller damage 3. Too small flow 4. The pump shaft and the motor are not concentric 5. Bearing damage 6. Air is mixed in. Cavitation occurs
Solution: 1. Disassemble and remove foreign objects 2. Replace the impeller 3. Slightly open the outlet valve 4. Alignment at fixed point 5. Change suction position to improve water absorption
