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.

Oil motor cache file control circuit

When the motor stops rotating, scored inversely proportional to the hydraulic directional valve position within the system, hydraulic directional valve is inversely proportional to effect on the drawing for type O, which is closed system, the motor due to the inertia moment, is the developmental tendency of rotation, thus in the oil return of the motor mouth causing a flash of high pressure (destructive) is the pressure, The pressure of the high pressure oil exceeds the linear pressure of the speed regulating valve. According to the overflow effect of the speed regulating valve of the hydraulic system motor, the high pressure oil of the oil inlet of the oil motor leaks to the oil inlet of the motor according to the speed regulating valve.

Because the brake tube is closed, the oil in the motor inlet can not be filled immediately when the motor of the synchronous hydraulic motor rotates, which will lead to suction, and the pressure oil in the oil inlet overflow into the motor inlet, which can relieve the motor suction difficulty and fill the oil inlet.

Because the oil motor can rotate in two directions, the speed regulating valve of the cache file control circuit is set up two.
