Dust and Gas Industry Explosion-proof Brake YWZ5-400/50 Hengyang Heavy Industry Coal Mine Chemical Plant Use

If the left side of the hydraulic system schematic diagram for the output of high-pressure oil, so the hydraulic system suction and return oil can be directly in the case. Valve block is in addition to the oil pump and hydraulic cylinder, the integration of the components, gear pump output of high-pressure oil through the shut-off block into the hydraulic cylinder work. The positive and negative rotation of the motor realises the reciprocating motion of the piston rod of the hydraulic cylinder. The hydraulic parts are working in the closed steel cylinder tank, brake with electric hydraulic actuator principle electric hydraulic actuator principle AC motor through the coupling drive two-way gear pump work.

Will lead to increased internal and external leakage, reducing its mechanical efficiency. At the same time, due to higher temperatures, the hydraulic oil will expand, resulting in increased compression, so that the control action can not be well transmitted. Solution: heat is an inherent feature of the hydraulic system, can not be eradicated only try to reduce. The use of good quality hydraulic oil, hydraulic piping arrangement should try to avoid the emergence of elbows, the use of high-quality piping and fittings, hydraulic valves and so on.

 Hydraulic brakes and actuators are two essential components of machinery. Brake as the name suggests is a driving device to slow down or stop the machine. Because it is easy to use and has sufficient power. Mainly used in mining, dock, construction, metallurgy and other machinery industry. As a machine because of the technical environment and other reasons are limited, more working environment there are some requirements. Take hydraulic brake as an example:

    Environmental requirements for the use of hydraulic brakes:

    Ambient temperature: -40℃～+50℃.

    Relative humidity: ≤90%.

    Altitude: in accordance with the relevant provisions of GB755-2000.
