Abstract

The invention discloses a control system for a coal mine underground water-jet cutting machine. An oil tank (1) is communicated with a hydraulic pump (4); the hydraulic pump (4) is communicated with a second pilot operated directional control valve (9); the second pilot operated directional control valve (9) is communicated with the left oil cavity and the right oil cavity of a dual-purpose boosting cylinder (26) respectively; a first mandrel plunger valve (14) and a second mandrel plunger valve (15) are arranged in the left oil cavity and the right oil cavity respectively; the second mandrel plunger valve (15) is communicated with a first pilot operated directional control valve (8); the first mandrel plunger valve (14) is communicated with the first pilot operated directional control valve (8); the first pilot operated directional control valve (8) is communicated with the hydraulic pump (4); and the left water cavity and the right water cavity of the dual-purpose boosting cylinder (26) are communicated with an energy accumulator (23) and a water pump (22) respectively, so that a control system is formed as a whole. The entire system can be operated without generating electric sparks or other sparks, can be applied to occasions such as mining, fire control, rescue, explosion protection and the like, and is particular suitable for performing coal mine underground cutting operation.

Description

technical field [0001] The invention relates to a water cutting machine, in particular to a control system for a coal mine underground water cutting machine. technical background [0002] Since the first commercial abrasive waterjet cutting machine was used to cut automotive glass, with the development of science and technology and some special requirements for material cutting, the application field of waterjet technology has expanded rapidly. The water cutting machine uses high-pressure water jets to cut materials. It belongs to cold cutting. It directly uses the kinetic energy of sand-added water jets to cut metals to achieve the purpose of cutting. There is no chemical change during the cutting process, and it has no effect on the physical and chemical properties of the cutting materials. No thermal deformation, narrow slit, high precision, smooth cutting surface, clean and pollution-free, etc. Waterjet cutting machine is currently the machine with the highest produ...
