Hydraulic pump maintenance is mainly the correct use and management of the pump, timely treatment of abnormalities in operation, filtering the working medium, troubleshooting small faults in order to improve the use of hydraulic pumps in a timely manner, to ensure the normal operation of the pump, to extend the service life of the pump.
The main causes of damage to the hydraulic pump are:
1. Pump parts wear, corrosion, fatigue damage;
2. Pump manufacturing factors or accidents.
The essence of repairing normal or abnormal causes of pump damage is to compensate for its deterioration.
Repair of hydraulic pumps have two basic methods: repair and replacement.
The main principle of selecting a hydraulic pump is the type of main equipment; the main factors to be considered when selecting a hydraulic pump are structural form, working pressure, flow rate, speed, efficiency, quantitative or variable, variable mode, life expectancy, type of prime mover, noise, pressure volatility, self-priming ability, compatibility. With hydraulic fluid, size, quality, economy and maintenance.
Points to note in hydraulic pump repair:
In hydraulic pump repair, many parts of the bolts are specified torque requirements, such as the transmission box, cylinder head, hub, connecting rod and front axle, etc., tightening torque in the manual have special provisions, do not arbitrarily change. If the wrong bolt or torque is used, it may cause a part of the hydraulic pump to loosen, thus causing damage.
When the hydraulic pump overload work, or the water tank is not enough water or heat dissipation is not good, after a long time of work, in order to quickly cool quickly, immediately add cold water to the tank. This practice is wrong, and may cause the cylinder head and cylinder block to blow up. We should let the hydraulic pump cool down after adding coolant to ensure the cooling effect.
