XHJ11 ton construction machinery winch

product description:

XHSJ seriesThe hydraulic winch is composed of various flow distributors with one-way balance valve and high-pressure shuttle valve to control the brake, XH series hydraulic motor, Z-type brake, C-type gear reducer, reel, frame and other components (the hydraulic principle is shown in the figure ), the user only needs to be equipped with a pump station and a reversing valve. Since the winch has its own valve group, it not only simplifies the hydraulic system but also improves the reliability of the transmission. The hydraulic valve group that comes with the XHSJ winch successfully solves the problems of empty hook vibration and secondary sliding during lifting in general winches, making the XHSJ hydraulic winch run smoothly during lifting and lowering. In addition, it also has the characteristics of high efficiency when starting and working, low energy consumption, low noise, beautiful appearance, compact size, and good economy. It can be applied to gravity crushing traction equipment, crawler and marine cranes, truck cranes, In equipment such as pipelayers, grab buckets and drilling rigs with crushing functions.

Product model example:

XHSJ6-120-315-30-ZPH said:

The modulus of the planetary reducer is 6, the tension of the first layer of the wire rope is 120KN, the rope capacity of the drum is 315m, the diameter of the wire rope is 30, a hydraulic winch with a brake and a one-way balance valve, and a pressure rating of 20MPa.

Product model description:

Product parameter description :

1. The total displacement of this series of winches is the amount of oil supplied per revolution of the drum.

2. The oil supply volume is the theoretical flow rate of the pump station, that is, the calculated value obtained by considering the system efficiency of 90%.

3. The rope capacity is the theoretical maximum rope capacity of the winch , and the actual allowable effective rope capacity should consider keeping 3 turns of the wire rope for use to prevent the rope end from falling out.

轴向柱塞泵液压马达

轴向柱塞泵常被船用液压马达生产厂家用于低速档大转矩液压电机。它们排量大，导出扭矩大，转速比低，速度慢，可靠性好。在一些低速齿轮中，它们每分钟旋转一次，甚至在零点几次，因此它们可以直接与工作机构连接，而无需减速设备，从而大大简化了传动机构,广泛运用于重型设备中。

液压电机与液压泵的异同

①同样：液压电机和液压泵原则上是一致的，热传递是根据密封工作中腔的体积变化完成的。

②不同之处：

液压电机的建筑容积率低于液压泵。而且液压马达的输入输出转速比相对于液压泵低。液压马达构造对称性，且可正反转。可是，液压泵大多数只具备单向性。除开进液口、出油孔，液压马达还具备泄油口，但液压泵并没有。
