choice Cast iron gate The main principle is the main equipment type; the main factors to be considered when selecting the hydraulic pump are structural form, working pressure, flow rate, speed, efficiency, quantity or variable, variable mode, life, type of prime mover, noise, pressure fluctuation rate, self-priming capacity, compatibility, hydraulic oil, size, quality, economy, maintainability, etc
Selection of hydraulic pump type
When selecting the type of hydraulic pump steel gate, we should base on: system operating conditions, system working pressure and flow, working environment, etc.
1. Select a single actuator according to the operating conditions of the system
When the speed is constant, fixed pump is selected; for fast and slow running conditions, double pump or multi pump is selected; when pressure maintenance is required for variable speed operation, variable pump is selected.
2. Select according to the working pressure and flow rate of the system
High pressure pump or high pressure gear pump.
3. According to the working environment
For field operation and harsh environment, gear pump or plunger pump is selected; vane pump, gear pump or plunger pump is selected for indoor or fixed equipment or environment.
After determining the type of the hydraulic pump, determine its specification and model according to the pressure and flow required by the system.
Maintenance and repair of hydraulic pump
The maintenance of the hydraulic pump is mainly for the correct use of the pump management and timely operation of the abnormal state, as well as the filtration of the working medium and elimination of minor faults; therefore, the use of the hydraulic pump is timely improved to ensure the normal operation of the pump. Prolong the service life of the pump.
The main reasons for the damage of hydraulic pump are: wear, corrosion, fatigue damage of internal parts of the pump; manufacturing factors or pump accidents. Repair of pump damage due to normal or abnormal conditions is basically compensation for its deterioration. There are two basic methods to repair the hydraulic pump, namely repair and replacement.
