Problems solved by technology

In actual work, the high-pressure hydraulic source in the coal mine not only supplies fluid to the water cutting machine, but also supplies fluid to other hydraulic systems, such as underground hydraulic supports, hydraulic props, hydraulic motors, etc. When the hydraulic source supplies fluid to these hydraulic mechanisms At this time, the pressure of the entire hydraulic system begins to decrease, and the hydraul

Abstract

The invention discloses a design of a pressurization compensation type front-mixing power-supply-free water cutting machine for a coal mine. The design of the pressurization compensation type front-mixing power-supply-free water cutting machine for the coal mine comprises a pressurization compensator, a pressurization compensator flange fastening bolt, a pressurization compensator diverter valve body, a one-way valve, a pressurization compensator flange plate, a base, a pressurization compensator liquid inlet pipe, a mixing valve liquid inlet pipe, a mixing valve, an abrasive mixer flange plate and an abrasive mixer, a liquid inlet pipe K-shaped connector, an underpressure and overpressure protection valve, a liquid supply K-shaped connector, a liquid supply pressure gauge, a working pressure gauge, a push-pull handle, an end cover, an unloading valve, a flow adjusting hand wheel, a safety valve, trundles, a protection plate, a sand amount adjusting valve and a liquid outlet K-shaped connector. Liquid supplied by the hydraulic source enters the pressurization compensator through the liquid inlet K-shaped connector and the underpressure and overpressure protection valve, part of theliquid flows into the pressurization compensator, and the other part of the liquid enters an abrasive mixing tank; when the pressure of the hydraulic source is reduced and fluctuates, the pressurization compensator starts to release liquid to supplement liquid to a hydraulic system, so that the pressure of the system is not reduced, and the purpose of pressurization compensation is achieved.

Description

technical field [0001] The invention relates to the design of a pressurized compensation type front-mixing water cutting machine without power supply for coal mines, in particular a pressurized compensator when the pressure of the liquid supplied at the liquid inlet appears negative pressure pulse fluctuations. The liquid stored in the system is replenished to the system through the booster compensator diverter valve body; the replenished liquid is under the action of the one-way valve, the stored liquid will not flow back, and it can only replenish and boost the abrasive mixer to keep the system pressure from falling. . Background technique [0002] At present, most of the pre-mixed water cutting machines without power supply used in coal mines use the existing high-pressure hydraulic sources in coal mines to supply liquid, such as coal seam water injection pumps, emulsion pumps, etc. The liquid is supplied to the water jet nozzle through the abrasive mixer. The mixed liqu...
