Safety Protection Method for the Ultra-high Pressure Hydraulic Slotting Device

The invention relates to a safety protection method for the ultra-high pressure hydraulic slotting device, belonging to the technical field of coal mine safety protection, which comprises the following steps of, S: The adjustable safety valve is installed on the ultra-high pressure fresh water pump to realize the water source safety protection of the ultra-high pressure hydraulic slotting device; S2: The ultra-high pressure hydraulic hosepipe, the ultra-high pressure rotating water tail and the ultra-high pressure sealing drill pipe are connected between the ultra-high pressure fresh water pump and the high and low pressure conversion slotting device to realize the safety protection of the transmission process of the ultra-high pressure water; S3: The remote operation platform is set up on the ultra-high pressure hydraulic hosepipe to ensure the operation safety of the ultra-high pressure hydraulic slotting operation; S4: Specific safety protection measures are taken at the joints between the ultra-high pressure hydraulic hosepipes and between the ultra-high pressure rotating hosepipe and the ultra-high pressure hydraulic hosepipe, so as to realize the safety protection of the connection position of the ultra-high pressure hydraulic hosepipe. The invention sets up a complete safety protection system that greatly improves the operation safety of the high-pressure hydraulic slotting device, and effectively avoids the occurrence of equipment safety accidents. -1/2 Ultra-high pressure fresh water pump is installed with adjustable safety First class protection: valve, which can effectively prevent the pressure overload ofultra-high pressure fresh water pump. When the pump output pressure exceeds the Safety protection ofsource ofultra- threshold value, the safety valve automatically opens for pressure relief. When the pump is re-started, the internal components ofthe safety valve automatically reset and can be reused. The ultra-high pressure hydraulic hosepipe is mainly made ofouter Second class protection: PVC steel wire rubber hose and inner steel wire spiral hose, which can bear 150 MPa and ensure the safe transmission of high pressure water Safety protection ofultra-high of lOOMPa. In addition, the ultra-high pressure rotating water tail and ultra-high pressure sealing drill pipe meet the high pressure sealing transmission requirements. Third class protection: The long-distance operation ofultra-high pressure hydraulic slotting is achieved with the remote op
