250bar Multistage Centrifugal Water Pump

What are the common faults and treatment methods in the work of high-pressure pumps?

错误3:pu后没有流或流量不足mp is started, the pressure is pulsating, and the pipeline shakes

Reason: 1. The air in the pump chamber is not exhausted. 2. The plunger is not properly sealed. 3. The suction filter is clogged. 4. The pressure relief valve or the pressure relief valve is malfunctioning. 5. The pipette is too long and too long.

Solution: 1. Exhaust 2. Replacement, maintenance 3. Cleaning 4. Inspection and elimination 5. Replacement of increased water volume

Fault two: no pressure or insufficient pressure

Reason: 1. The manual pressure relief valve has poor sealing and the pressure adjustment spring is fatigued. 2. The nozzle hole is worn.

Solution: 1. Repair 2. Replace

Trouble three: running noise, big impact, loud sound

Reason: 1. The crankshaft and the bearing bush are severely worn, the clearance is too large, and the connecting rod screw moves.

2. There is debris in the pump, and the gear is damaged 3. Insufficient liquid

Solution: 1. Replace, tighten 2. Clean, replace 3. Check

Fault 4: abnormal oil temperature rise

Reason: 1. Insufficient or excessive oil, oil pollution, oil quantity mismatch, poor viscosity 2. Large gap in the transmission part, friction of auxiliary parts, long running time

Solution: 1. Control according to regulations 2. Check, replace and adjust

Fault five: pump pressure suddenly rises

Reason: The safety valve is faulty, the pressure relief valve is faulty, and the system is faulty.

Solution: Check whether there is maintenance troubleshooting

Fault six: oil leakage lubrication

Reason: 1. The cylinder wall is pulled 2. The piston ring is damaged

Solution: repair and replacement

Fault seven: the cabinet temperature is too high

Reason: 1. Insufficient or excessive lubricating oil 2. The lubricating oil is too dirty, the bearing bush is damaged or starting

Solution: 1. Refuel or clean the oil tank to change the oil 2. Repair the crankshaft or replace the crankshaft r\n

Fault six: serious leakage of plunger seal

Reason: 1. Worn or damaged seal ring. 2 There are serious scratches and scratches on the surface of the plunger.

Solution: 1. Replace the sealing ring 2. Replace or repair the plunger
