The performance of the well stabilising winch is very excellent, so it is very widely used in the market. Many users choose underground mining winch when they buy mining winches, but they must be operated in accordance with the requirements when they are used, otherwise they are prone to failure. In particular, the protection system of the mine winch is prone to problems, but this problem is usually the cause of the brake, as long as it is replaced in time.
Any problems with the underground mining winch, check the protection system. Something wrong with the protection of the shoes, there is no safety circuit, you have to replace the brake pads, that sort of thing, but something can go wrong with the electrical components, the hydraulic station components, anything, but it's not a big enough mistake that you have to understand the system to fix it. The deceleration point is on the depth indicator, just switch the deceleration point up and down on the travel switch and you can place it however you want.
Inverter mine shaft sinking winch inverter failure, also on the line failure, the control program is generally not a problem, you can not change, protection is not much of a problem. Hydraulic station, not hydraulic pump, pump in addition to burn which has a problem, hydraulic station problem is also a valve problem, such as valve burned, or adjust the place where the need to adjust the oil pipe leakage or blockage. General that thing in addition to bad pieces will not be bad. In a word, you want to repair this thing you have to understand the schematic, or how to say is useless.
Underground mining winch to use DC, AC cut resistance, AC frequency conversion cut resistance winch hydraulic station voltage regulation are the same. Shaft sinking winch pressure regulation method is basically using electro-hydraulic proportional valve for pressure regulation. That is, the electronic control system sends a control voltage or current to the proportional valve, control voltage (current) and system pressure is basically a linear relationship, the greater the voltage (current), the greater the hydraulic station pressure.
The actual use of coal, large enterprises use coal caused by soot pollution management, decentralised coal soot pollution, such as small coal-fired boilers, fuel coal soot pollution, 1 tonne of coal caused by coal-fired boiler pollution management, 100 tonnes of coal caused by pollution, and now, in order to prevent air pollution restrictions on the use of coal, coal enterprises began to. China's coal management by the principle of systems engineering, a decentralised and reduce the use of coal, the use of natural gas and clean fuels, the second is the need for coal enterprises focusing on the elimination of backward coal, the use of clean coal technology management.
