XHC140000

Product selection instructions:

(1), XHSC hydraulic transmission allows working under high pressure.

(2), the maximum allowable pressure of the shell is 0.8MPa, if you have special requirements, please contact the manufacturer.

(3) Hydraulic oil: It is recommended to use high-quality, anti-foam, anti-oxidation mineral-based hydraulic oil. The ideal working oil temperature is 30°C~50°C, and the allowable oil temperature is - 20°C~80°C, when the oil temperature is lower than 10°C, low-condensation hydraulic oil must be used. The viscosity of the hydraulic oil is 40-60 centistokes, and the allowable value is 5-300 centistokes.

(4), the hydraulic oil filtration accuracy is recommended to be 25um or higher.

(5) The hydraulic transmission device can rotate in both directions, see the attached picture for the specific rotation. If the user's requirement is opposite to that shown in the illustration, please specify when ordering.

(6) Oil drain pipe positioning: XHSC transmission allows installation in any direction. In order to ensure the lubrication of each movement pair in the motor, it is required to fill the motor with hydraulic oil before work. The location of the drain port must be selected to ensure that the housing is filled with hydraulic oil during operation.

(7) Selection of distributors: various hydraulic transmission devices can choose distributors of various specifications according to different working conditions. The speed, flow rate, connection mode and the requirements of the integrated valve group should be considered; distributor installation: the direction of the inlet and outlet of the distributor is allowed to rotate at intervals of 72 degrees according to the shape of the connection position, but when the screw is loosened and rotated, be careful not to damage it The sealing function of the flat O-ring.

Note: The XH hydraulic transmission device can be equipped with our company's XHM, XHS, XHGS, XHCA, XHBD and other motors according to the working conditions and service life to meet different customer needs.

    当电机停止转动的情形下，系统内的液压换向阀打进成反比位置，液压换向阀的成反比作用为O型，也就是密闭式刹车管，这时电机由于惯性力矩，也是有转动的发展趋向，因而在电机的回油口导致一瞬间的髙压（也就是造成了工作压力破坏性），打桩机动力头改装此髙压油的工作压力超出调速阀的线性度工作压力，依据调速阀的溢流式功效，油电机回油孔的髙压油依据调速阀泄到电机的进油口。

    由于刹车管关闭，电机的进油口在电机转动的情形下机油不能马上填充，这时小型打桩机动力头会导致吸空，而回油孔的工作压力油溢流式到电机进油孔，可以缓解电机吸空难点，给进油孔填充了机油。

    由于油电机可以正反两面向2个方向旋转，因而缓存文件控制电路的调速阀设置了2个。变压控制电路绝大多数都是应用调速阀的变压基本概念来变压的，因而调速阀别觉得简单明了，其适用范围挺大着呢。
