There was a problem with Underground Mining Scraper Winch found on the protection system. For example, the brake shoe can protect the problem, the safety circuit is gone, you have to replace the brake, and so on. Which Underground Mining Scraper Winch has electrical components and hydraulic station components, which may be wrong, but not a big mistake, you need to understand the system to be repaired. The deceleration point is on the depth indicator. It is best to change the position of the upper and lower deceleration points and the limit switch. Where I want to slow it down.
Inverter winch, inverter failure, line failure, control program is generally no problem, can not be changed, protection is no problem. Hydraulic stations are prone to failure, not hydraulic pumps. In addition to problems with combustion pumps, for example, valves are also burned, or need to be adjusted, and oil pipes are leaking or blocked. Normally, everything will not break except the bad parts. In short, if you want to fix this, you need to understand the schematic. It doesn't matter if you don't say it. Underground Mining Scraper Winch
Underground Mining Scraper Winch's hydraulic Underground Mining Scraper Winch uses the same DC, AC cutting resistance, and AC variable frequency cutting resistance as Underground Mining Scraper Winch. At present, the winch pressure adjustment method mainly uses an electro-hydraulic proportional valve for pressure adjustment. In other words, the electronic control system sends the control voltage or current to the proportional valve, and the control voltage (flow) and the system pressure are basically linear. The greater the voltage (flow), the greater the pressure at the hydraulic station.
