Problems solved by technology

The former method mainly has the following problems: (1). Because the sand nozzle is prone to slight sand blocking when there is no water flow impact or the water flow pressure is too small, and the current high-pressure water switch valve technology is not yet mature, the work The performance and stability are poor. In the ultra-high pressure state, the high-pressure water switch valve is prone to micro leakage. Once there is a small leakage, the backwater phenomenon will occur at any time; (2). In the ultra-high pressure state, the high pressure The spool parts of the water switching valve are easily dam...

Abstract

A backwater control system of hydraulic cutting machine is composed of water nozzle, sand nozzle, mixing cavity between the said two nozzles and connected to sand delivering pipe, and a high-pressure water generator system having a boosting unit and a high-pressure water accumulator connected to the said water nozzle. It features that a by-pass channel communicated with the said mixing cavity is used for discharging the backwater via a normally opened valve. Its advantages are simple structure and low cost.
