The causes and treatment methods for insufficient pressure in multistage pumps can be analyzed and resolved from multiple perspectives. As a senior manufacturer of multistage pumps, Changsha Zoomlian Pump Industry has rich experience in repairing multistage pump faults. In this article, the technical personnel of Zoomlian Pump Industry list the following causes of insufficient pressure in multistage pumps and corresponding treatment methods for your reference.
- Insufficient motor power: The pressure output of a multistage pump is directly related to the power of the motor. If the motor power is insufficient, it will directly affect the output pressure of the pump. The solution is to replace the motor with a larger power one or increase the motor power.
- Insufficient rotating speed of the multistage pump: The rotating speed of the multistage pump directly affects its output pressure. If the rotating speed of the pump is insufficient, it will also lead to insufficient pressure. Check and adjust the rotating speed of the pump to an appropriate range.
- Poor sealing of the multistage pump: The sealing performance of the multistage pump has an important impact on the pressure. If the sealing is poor, it will cause internal leakage, thus affecting the pressure output. Check and replace the damaged seals.
- Damaged impeller: The impeller is the core component of the multistage pump. If the impeller is damaged, it will directly affect the flow rate and pressure of the pump. Check whether the impeller is damaged and replace it.
- Blocked inlet pipeline: If the inlet pipeline of the multistage pump is blocked, the pump will not be able to suck in liquid normally, which will further affect the pressure output. Clean up the impurities and blockages in the inlet pipeline.
- Loose suction pipe joint: If the suction pipe joint is not tight, it will cause air intake, affecting the normal operation of the multistage pump. Check and fasten the suction pipe joint.
- Insufficient valve opening: If the valve opening is not enough, it will also lead to insufficient pressure. Check the valve switch position and adjust it to an appropriate opening.
- Bent pump shaft or excessive bearing wear: These will affect the normal operation of the multistage pump, resulting in insufficient pressure. It is necessary to disassemble the pump to correct or replace the shaft, and overhaul the bearing.
- Blocked intake pipe or too small opening: This will cause cavitation, affecting the normal operation of the multistage pump. Check whether the intake pipe is blocked or its opening is too small, and make corresponding adjustments.
From the above analysis, we can see that there are various reasons for insufficient pressure in multistage pumps, and targeted inspection and treatment need to be carried out according to specific conditions. In actual operation, we should combine specific situations, check the above possible reasons one by one, and take corresponding solutions.
