The performance of the mining double drum hoist winch used for drilling wells is very excellent, so it is widely used in the market. Many users choose underground mining winch when purchasing them, but they must operate them according to the requirements when using them, otherwise they are prone to malfunctions. Especially the protection system of the shaft sinking winch is prone to problems, but these problems are usually caused by the brakes, as long as they are replaced in a timely manner.
If there is any problem with the double drum hoist winch, check the protection system. There is a problem with the protection of the shoes, there is no safety circuit, you have to replace the brake pads, and so on, but electrical components, hydraulic station components, anything can have problems, but this is not a big mistake, you must understand the system to fix it. The deceleration point is located on the depth indicator, and you can place it freely by simply switching the travel switch of the deceleration point up and down.
The frequency converter of the variable frequency underground mining winch is faulty, which means there is a circuit fault. The control program is generally fine, and you cannot change it. There is also no problem with protection. A hydraulic station is not a hydraulic pump. There is no problem with a pump other than burning out. The problem with a hydraulic station is also a valve problem, such as a valve burning out, or a need to adjust the regulating area, or an oil pipe leaking or being blocked. Usually, that thing won't break except for broken parts.
The hydraulic station voltage regulation of shaft sinking winch using DC, AC cutting resistors, and AC variable frequency cutting resistors is the same. The current method of regulating winch pressure is basically to use electro-hydraulic proportional valves for pressure regulation. The electronic control system sends a control voltage or current to the proportional valve, and the control voltage (current) is basically linearly related to the system pressure. The larger the voltage (current), the higher the hydraulic station pressure.
