How can we use the hydraulic pump?

hydraulic pump adjusts the power of the pump. Clockwise adjustment means an increase in power, counterclockwise adjustment means a decrease. The formula: Power is equal to pressure multiplied by the flow rate. Under the condition that the motor speed is constant and the pressure is constant, the greater the power, the higher the pump power is. The more traffic is spent. It should be noted that both pumps should be set together with 90° as the setting value.

What is the function of the hydraulic pump?

The hydraulic pump is a hydraulic component that provides pressurized fluid for hydraulic transmission, and is a kind of pump. Its function is to convert the mechanical energy of power machines (e.g., electric motors and internal combustion engines) into liquid pressure energy. There are many factors that affect the service life of the hydraulic pump, in addition to the design and manufacturing factors of the pump itself, the selection of some components related to the use of the pump (such as couplings, oil filters, etc.), and operation during commissioning are also related.

How to deal with the noise of the hydraulic pump?

Abnormal noise of hydraulic pump, should be checked in time

1.Stop the pump with unusual noise while working, check the oil return filter element for iron chips and copper chips.

2.It is necessary to disassemble the hydraulic pump, check the individual damaged parts of the manifold plate of the pump bubble piston and the swashplate seat of the swashplate, and analyze whether the hydraulic oil is not enough for other reasons, and whether there is a possibility of going into the air.

3.The abnormal noises of cold car and normal hot car are generally due to the hydraulic oil being too dirty and the oil return filter element being clogged. It is necessary to replace the filter element and hydraulic oil in time to observe the test machine. 4.The oil leak during work causes the hydraulic oil level to be too low to produce abnormal noise. Should be stopped in time for inspection, refill hydraulic oil.

What types of hydraulic pumps are there?

1.Whether the flow can be adjusted: variable pump and quantitative pump. The output flow can be adjusted according to the needs called variable pump, the flow can not be adjusted as quantitative pump.

2.According to the pump structure commonly used in hydraulic system, it is divided into: gear pump, vane pump and piston pump Gear pump: small size, simple structure, strong environmental protection, low price; large leakage, strong noise, strong flow pulsation, discharge The quantity cannot be adjusted.

3.Wing cell pump: divided into double acting vane cell pump and single acting vane cell pump. This type of pump has uniform flow, stable operation, low noise, higher working pressure and higher volumetric efficiency than a gear pump, and more complicated structure than a gear pump.

4.Piston pump: high volumetric efficiency, low leakage, can work under high pressure, mostly used in high performance hydraulic systems; but complex structure, high demands on material and processing accuracy, high price and high demands on oil purity.
