Product overview

XYJ series hydraulic winch is composed of various integrated valve blocks, hydraulic motors, brakes, planetary reducer, winding, racks and clutches with one-way balance valve and high pressure shuttle valve controlling brake. Users only need to be equipped with pump station and reversing valve. Because the winch has its own valve set, it not only simplifies the hydraulic system but also improves the working reliability of the transmission device.

In addition, it also has the characteristics of high efficiency, large power, less energy consumption, low noise, beautiful appearance, compact size, good economy and so on. The product can be widely used in construction engineering, petroleum, coal mining, machinery, geological drilling, ship deck machinery and other equipment, the product has not only sold well in the whole country, And exported to the Middle East, Southeast Asia, India, South Korea, Russia, Australia, the United States, the Netherlands and other countries and regions.

Hydraulic motor in the process of using very easy to happen some problem, in which is for the common power reduce, load of the hydraulic motor speed than many and large noise reduction, vibration of the three, below the main lesson is generally common faults of hydraulic motor and solution, looking forward to effect to everyone.

Hydraulic motor

Problem 1. The export rate of centrifugal impeller hydraulic motor is not enough (underspeed), and the power of gear hydraulic motor is reduced.

Reason:

1. The oil provided by the hydraulic pump is not enough.

2. The motor fusion surface is not tightened or the sealing is not good, and there is steam leakage.

3. The blade is stuck to the rotor groove of the motor because of pollutants or rough edges.

4, the flow passage of throttle valve in the case of environmental pollution, and then blocked, resulting in no working pressure at the bottom of the blade elbow blade (especially at low speed), so that it can not be fixed on the stator surface of the motor.

5, because the oil temperature is too high or the oil viscosity is not appropriate.
