electric winch

product description:

XHDJ electric winch is made by our factory technicians with many years of experience and continuous innovation and improvement. It is driven by JZ2-H marine electric motor, through elastic coupling, closed gear reducer, open large and small gears, and jaw clutch to drive the reel to rotate. It adopts electromagnetic brake, equipped with manual band brake and manual clutch. The product is compact in structure, small in size, light in weight, large in lifting capacity, and easy to use, and is widely used in various lifting equipment such as ships, oil fields, coal mines, and ports.

The JZ2-H marine motor selected by the winch is equipped with an automatic control box and an electromagnetic brake, which is convenient for long-distance control and can realize the brake protection function. The motor has a high protection level (IP56), wind, sand and rain have no effect on the use of the motor, and is suitable for outdoor use. When the jaw clutch is disengaged, the empty hook can be lowered freely, which greatly improves the working efficiency. When the winch is not working, lock the belt type manual brake to achieve braking and effectively protect the open gear and the reduction box.

The models of electric winches produced by our factory are: XHDJ50, XHDJ100, XHDJ150, XHDJ200, XHDJ300, XHDJ400. The lifting capacity ranges from 5 tons to 40 tons, and there are many varieties and complete types, which is convenient for users to choose. At the same time, various types of electric winches can be customized according to customer requirements.

1、低速大扭矩液压马达一般允许在短时间内超出额定压力20%-30%的压力下工作，但瞬间的高压力不能和高转速同时出现。

2、液压马达的回油路背压有一定限定，在背压较大时，必须设定泄漏油管。

3、液压电机的大转矩和高转速一般不应同时出现。

①实际转速不得小于电机的低转速，以免爬行。

4、为避免制动电机气蚀或因泵工作而丧失制动能力，应保证电机出油口有足够的补油压力。

①它可以通过封闭中的补油泵或开式回路中的背压阀实现；

②当液压电机驱动大惯量负载时，应在液压系统中设置与电机并联的旁路单向阀，以防止打桩机动力头减速机在关过程中惯性运动时缺油。

②当系统要求的转速低，而马达在转速、转距等性能参数不易满足工作标准时，能在马达以及驱动的主机间加设减速机构。

③为了在极低速度下平稳运行，电机泄漏必须稳定，泵油背压至少35℃油的粘度。
