Mine winch The hydraulic winch adopts DC, AC cutting resistance winch and AC variable frequency cutting resistance winch
The performance of the mine winch is very good, so it is widely used in the market. Many users choose the mine winch when purchasing the winch, but they must operate according to the requirements when using it, otherwise it is easy to have faults. In particular, the brake system is prone to problems. Please replace it in time. There are problems with the winch. These problems are found in the protection system. For example, the brake shoe protection problem, the safety circuit disappears, you need to replace the brake, other similar but electrical components and hydraulic station components, this may be wrong, but it is not a big mistake, you need to know the system to be repaired. The deceleration point is located on the depth indicator. The up and down travel switch position is changed.
Inverter winch, inverter fault, line fault, control program generally no problem, can not be changed, protection no problem. Hydraulic station is not a hydraulic pump. In addition to the combustion pump problem, the hydraulic station problem is also a valve problem. For example, the valve is burnt out, or the adjustment position needs to be adjusted, and the oil pipe leaks or is blocked. Generally speaking, things don't go bad except for the bad parts. In short, if you want to solve this problem, you have to understand the schematic. If you don't say it, it doesn't matter that the hydraulic winch of mine winch adopts DC. The AC cutting resistance and AC frequency conversion cutting resistance winch are the same. At present, the winch pressure regulating method mainly adopts the electro-hydraulic proportional valve. In other words, the electronic control system sends control voltage or current to the proportional valve, and the control voltage (flow rate) is basically linear with the system pressure. The greater the voltage (flow), the greater the pressure of the hydraulic station.
