    Do you know these techniques? Safety operation technology of high pressure oil pump!

    1. It is necessary to ground the power supply and the enclosure. The test can be carried out only after the insulation of the line is checked. 2. Before the high-pressure oil pump works, loosen the regulating valves of each oil circuit, and then start the oil pump. After the empty load works normally, lock the oil return valve, gradually screw in the oil valve rod, increase the load, and pay attention to whether the pointer of the pressure gauge is normal. 3. When the oil pump stops working, the... Read More

  • Plunger pump cleaning pipeline operation

    Plunger pump cleaning pipeline operation

    Plunger pump is an important device of hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block to change the volume of the sealing working chamber to complete oil absorption and pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow conditioning. As you know, a lot of pipes are used in industrial consumption to transport all kinds of liquid, gas, solid-liquid mixture and other substances ... Read More

  • Difference between hydraulic pump and hydraulic motor

    Difference between hydraulic pump and hydraulic motor

    1. Different output modes. The hydraulic pump is a conversion device that converts the mechanical energy of the motor into the hydraulic energy, and outputs the flow and pressure, hoping the volume efficiency is high; the hydraulic motor is a conversion device that converts the pressure energy of the liquid into the mechanical energy, hoping the mechanical efficiency is high. Therefore, the hydraulic pump is the energy device, and the hydraulic motor is the actuator. 2. The output shaft turns di... Read More

    What is the function of the hydraulic pump

    What is the function of the hydraulic pump? The function of hydraulic pump is to convert the mechanical energy of power machine (such as motor and internal combustion engine) into the pressure energy of liquid. The hydraulic pump is a kind of pump, which is driven by engine or motor, sucks oil from the hydraulic oil tank, forms pressure oil to discharge, and sends it to the actuator. There are many factors that affect the service life of the hydraulic pump. In addition to the design and manufact... Read More

  • What are the common faults of vane pump?

    What are the common faults of vane pump?

    1、 Determination of common faults of vane pump: 1. Grinding pump (burning plate): cause: the oil is too dirty, improper installation, water enters the oil, and there are iron chips in the oil (new machine market occurs). 2. High oil temperature or insufficient parts manufacturing accuracy. 3. High noise of vane pump: especially large a. Air leaks at the oil inlet. (O-ring seal failure, screw too long or flange too thin) b. The filter is blocked and the oil flow is insufficient. c. The viscosity ... Read More
