1. Hydraulic pump not supplying oil or insufficient oil supply

-Pump not turning or running in reverse: Check electrical components, motor direction, connection keys, and hydraulic components (such as relief valves and one-way valves), and repair faults
-Pump shaft issue: Check if the pump shaft is broken, replace it if necessary, and disassemble and repair the sliding parts inside the pump to ensure that the assembly clearance meets the standards. At the same time, pay attention to the quality of the oil and the cooling condition
-The pump cannot absorb oil: Firstly, diagnose the oil absorption obstacle and solve it accordingly
-* * Decreased efficiency * *: Disassemble the pump body, clean, repair or replace worn parts, grind the oil distribution plate, update bearings and plungers, and reassemble to technical standards.

2. The pump operates with loud noise

-* * Vacuum phenomenon * *: Clean or replace clogged filter screens, adjust suction pipe layout, and reinforce sealed connections
-* * Inhalation of air * *: No load exhaust operation, extend the suction pipe
-Mechanical wear: Check the wear of the bearings and components inside the pump, and repair and replace them in a timely manner.

3. Pressure and flow fluctuations

-Installation issue: As above, ensure unobstructed oil suction path and strengthen sealing
-Bubble impact: Similarly, empty exhaust is adopted to optimize the oil suction system
-Oil contamination: Replace or filter the oil to ensure cleanliness.

 4. Abnormal fever

-Improper assembly or oil problems: Check the assembly clearance, select qualified hydraulic oil, clean and replace contaminated oil
-Internal leakage and low efficiency: It is also necessary to disassemble, clean, replace worn parts, grind damaged parts, and ensure the internal sealing and working efficiency of the pump body.

In short,handle When a hydraulic pump malfunctions, the root cause of the problem should be accurately diagnosed first, and then targeted measures such as cleaning, adjusting, replacing parts, or optimizing system configuration should be taken to ensure that the hydraulic system returns to stable operation
