Belt conveyor tensioner

The mining belt conveyor tensioning device developed by Ningbo Xinhong Hydraulic Co., Ltd. is a hydraulic system and winch assembly based on coal mine research and development, which can adapt to various working conditions and environments.

The mine belt conveying tensioning device consists of a mine winch and a mine tensioning hydraulic system. The winch has functions such as explosion-proof, high and low speed switching. It can provide a maximum traction force of 70KN, a maximum speed of 60m/min, and a rope capacity of 150M. The tensioning hydraulic system can provide the required hydraulic energy for the mine winch, with a maximum pressure of 28MPa and a maximum flow rate of 150L/min. It is integrated with switching valve group, proportional valve group, emergency release valve group and so on. With the cooperation of the above-mentioned mechanism, the mining belt conveyor tensioning device can realize the stepless variable speed output of the winch, and the sensor in the device can display the output speed in real time. With the tension sensor, it can detect the tension of the cable in real time, and automatically adjust the output speed according to the tension to meet various working conditions. When the tension of the cable is too large, the system will automatically release the cable to ensure that the output force of the cable is constant; when the tension of the cable is too small, it will quickly retract the cable to ensure that the cable is always in tension. At the same time, it is equipped with an automatic cable winding mode, which can quickly enter the working state after changing the cable or after a rest, increasing work efficiency. At the same time, there is an emergency mode, which can ensure that the winch is lowered to a safe position smoothly and slowly in the event of power failure or system damage, and the protection device and on-site personnel are safe and reliable.

液压绞车使用的情况下在所难免存有一些潜藏的现象，如果我们不仔细的清查是非常容易忽略的，依据这样的事情为大伙儿汇总了一些问题，接下来就给大伙儿介绍一下提升绞车存在的不足有什么：

一、不可以与此同时提人提物

尽管提升绞车有提物和提人的作用，不过确没法准确与此同时精准定位，为安全性留下了安全隐患。

二、制冷系统

在具体的作业中，经常会出现一会儿运行一会儿终止，冷却循环水没法准确关掉，产生的难题关键反映两方面：

1、水源的消耗。

2、扩大了井下的排放量。

三、液压绞车的通信系统

假如信号工并没有发出信号，驾驶员就拌动操纵杆，尽管数据信号锁闭系统软件锁闭电脑操作系统控制回路，使径向住塞泵不可以导出髙压齿轮油，rv蜗轮蜗杆减速机不可以转动，可是制动盘型闸早已开启，滚桶在作用力的功效下转动，因此引起安全事故。
