ZW self-priming sewage pump common faults and troubleshooting methods:
First, the phenomenon of failure (no water)
Cause Analysis:
1. The pump casing is not filled with fluid or the fluid is insufficient 2. The suction pipeline is leaking 3. The rotational speed is too low 4. The suction stroke is too high or the suction line is too long 5. The mechanical seal leaks too much 6. The suction line gas cannot be Export discharge exclusion method:
1. Add enough fluid 2. Check and eliminate leaks 3. Adjust the speed 4. Reduce the suction or shorten the suction line 5. Repair or replace 6. Make it discharge 2. Noise and vibration
1. The foot is unstable 2. The pump shaft is bent 3. The cavitation phenomenon 4. The bearing wears badly 5. There are debris in the import pipeline 6. The spindle of the pump and the electric motor do not agree with each other.
1. Reinforce 2. Replace or adjust 3. Adjust the working condition 4. Replace 5. Remove the debris 6. Adjust the concentricity 3. Insufficient water output
1. The impeller flow path and the suction pipe are blocked 2. The impeller or impeller seal wears badly 3. The power is insufficient or the speed is too low.
1. Remove plugs 2. Replace the ring 3. Add power and adjust to rated speed. 4. Analysis of shaft power consumption
1. The flow is too large 2. The speed is too high 3. The pump shaft bends or the impeller bumps 4. The flow path in the pump is blocked or stuck.
2. 1. Increase the outlet pressure correction appropriately reduced or 4. 3. Replace line plug-type self-priming sewage pump ZW Author: Wing pump manufacturers Jia Liangbang
Self-priming water pump is a kind of pump and motor connected, and at the same time submerged into the liquid pump work. ZW type self-priming sewage pump is a combination of self-priming and non-clogging sewage. It adopts an axial-recirculating mixing type and passes through the pump body. The unique design of the impeller runners allows the transport of clean water and sewage and manure with particles and fibers. Widely used in municipal sewage projects, ponds and manure handling, precipitation of waste impurities, light industry, paper, food, chemicals, pharmaceuticals, electric power, paddles and mixtures, etc. The sewage pump has a strong suction and non-clogging structural design.
