Application of high pressure circulating water cleaning system for hydraulic support
2021-04-09
The reliability of hydraulic support has a great influence on the safety production of fully mechanized working face. If the reliability of the support is poor and the failure occurs frequently in use, it is necessary to invest a lot of manpower and material resources for repair and maintenance. However, in the underground repair of the support, especially the replacement of parts, there are many disturbing factors in the poor working environment. Therefore, the hydraulic support in the well overhaul must ensure the quality of overhaul, and the support in the well before overhaul, the most important step is to clean the surface of the residual slime and rust.
At present, the support repair units in our country generally use the method of manual cleaning and water washing to clean the hydraulic support. This method must have 2-5 people working together, and has the disadvantages of high labor intensity, large water consumption and low efficiency. Some enterprises try to use emulsion pump as power, although the cleaning efficiency has been improved, but the emission pollution is very serious, which will have a great impact on the environment. Based on the above reasons, the industry urgently needs to find a better way to clean the hydraulic support, which has a very urgent need and practical significance for the repair of coal mine hydraulic support. Therefore, after repeated demonstration, the technicians finally decided to use the high-pressure circulating water cleaning system developed and produced by Beijing degaojie Cleaning Equipment Co., Ltd. to clean the hydraulic support.
