The underground explosion-proof command vehicle is becoming more and more popular on the construction site. Its use effect is very worthy of recognition. Even if the working environment is very harsh, its use effect is also very good. So, working under bad conditions will definitely inevitably cause malfunctions, just think we will encounter the problem of steering failure when using it. This is a more serious phenomenon and also more dangerous, so let's introduce it next What are the countermeasures when encountering this situation.

　　As the underground explosion-proof command vehicle was in use, there was a steering failure failure, and the steering wheel could not turn, or it could only be turned a little bit harder. The steering is controlled by the hydraulic steering gear. First, check whether the internal mechanism of the hydraulic steering gear is stuck, disassemble the steering gear, and see if any parts are falling off and stuck.

　　Check again to find whether there are small particles in the oil inlet of the steering gear valve block, and block the one-way valve near the oil inlet. After clearing the debris, the steering gear will return to normal.

　　Therefore, when other underground explosion-proof command vehicles have similar failures, they will be quickly eliminated. The source of these sundries was investigated. It turns out that there is a line gap oil filter on the oil return line of the hydraulic system. The adhesive used is easy to fall off. The fallen particles follow the oil return pipe to the fuel tank, and then pass the oil pump to the steering gear. Stay on the check valve and cause malfunction.

　　In order to reduce the phenomenon of steering failure, any components on the hydraulic system of the explosion-proof command vehicle should not be made of materials that are easy to fall off or will become fragments after being soaked in hydraulic oil, to avoid blockage caused by poor materials, hydraulic components Manufacturers should pay particular attention.

　　The above is about the measures when the underground explosion-proof command vehicle encounters the steering failure problem when using it. Because this phenomenon is more dangerous, we must follow the steps we introduced above. Only when we grasp the countermeasures to the problem in advance, we will not panic when it happens, and we can deal with it freely.
