The function of electric hydraulic pump is to convert the mechanical energy of the power machine into the pressure energy of the liquid effectively, the output flow can be adjusted according to the demand, we call it variable pump, the output flow can not be adjusted, called the quantitative pump.

1、Working principle

Electric hydraulic pump can effectively convert mechanical energy into fluid pressure energy, it can also be called an energy conversion device, electric hydraulic pump can effectively provide pressure oil to the hydraulic transmission system. In general, the hydraulic transmission technology used in a variety of pumps, are dependent on the size of the sealed working chamber alternating changes in volume to work, so they belong to the volume pump.

2、the work needs to have the conditions

Electric hydraulic pump studio needs to have certain conditions, the need for sealing performance, and variable working chamber, the volume of the working chamber can be increased or reduced from week to week, increased when the suction chamber for connection, become smaller when connected with the pressure chamber, here to remind you that the suction chamber and the pressure chamber can not communicate.

3、Classification of electric hydraulic pump

There are many types of electric hydraulic pumps, according to the shape of the main internal movement build and movement to classify, can be divided into gear pumps, vane pumps and piston pumps three.

1)、according to the hydraulic pump suction and discharge direction can be changed, can be divided into one-way pump and two-way pump, single-phase pump refers to the suction and discharge direction can not be changed, can be changed for the two-way pump.

2)、according to the electric hydraulic pump displacement can be adjusted can be divided into quantitative pump and variable pump two. Displacement simply means that the hydraulic pump in the absence of leakage, the pump shaft can remove the volume of liquid per rotation week, the size of the displacement and the geometry of the pump.

In a word, when choosing an electric hydraulic pump, you should have an understanding of the relevant content of the electric hydraulic pump, and it is best to choose a big brand of products, not just look at the price and ignore the quality.
