Device for cutting and cleaning pre-mixed high pressure suspension grinding material water jet

Abstract

The invention discloses a device for cutting and cleaning a pre-mixed high pressure suspension grinding material water jet, comprising a grinding material refilling device, a grinding material supplying device, a high pressure pump system, a grinding material isolating valve and a nozzle. The outlet of the high pressure pump system is divided into two paths, a main pipeline reaches a filling isolating valve and the nozzle through a throttle valve, a branch pipeline converges with the main pipeline through the throttle valve, an ejector and a grinding material supplying valve in sequence, the ejector is also connected with the grinding material supplying device through the pipeline, and the grinding material isolating valve is installed on the pipeline between the grinding material supplying device and the main pipeline at the back of the throttle valve. The invention has the anti-plugging function, effectively avoids the problem that the pressure changes in the working process or the grinding material possibly plugs the pipeline and the nozzle when the device is turned off, greatly reduces the abrasion to the filling isolating valve, can generate a stable and uniform high pressure suspension grinding material water jet in quantification according to different needs, and has remarkable cutting and cleaning effects.

Description

technical field [0001] The invention relates to an abrasive jet system in high-pressure water jet technology, in particular to a high-pressure pre-mixing suspension abrasive water jet cutting and cleaning device. Background technique [0002] The existing front-mixing abrasive water jet device is in direct contact with the abrasive when isolating the abrasive, and the surface of the valve seat is in direct contact, so the wear on the valve surface is great, especially at the moment of closing, it is easy to tear the contact surface of the valve Abrasion, the service life is very low and unreliable, and it is dangerous; secondly, when the system pressure changes or shuts down during the work process, abrasives often block the pipeline and nozzles. At present, the main means of solving the blockage problem are By increasing the uniformity of the mixing of abrasives and water, it is difficult to completely mix the abrasives and water evenly in the actual operation process, and ...

[0002] The existing front-mixing abrasive water jet device is in direct contact with the abrasive when isolating the abrasive, and the surface of the valve seat is in direct contact, so the wear on the valve surface is great, especially at the moment of closing, it is easy to tear the contact surface of the valve Abrasion, the service life is very low and unreliable, and it is dangerous; secondly, when the system pressure changes or shuts down during the work process, abrasives often block the pipeline and nozzles. At present, the main means of solving the blockage problem are By increasing the uniformity of the mixing of abrasives and water, it is difficult to completely mix the abrasives and water evenly in the actual operation process, and the problem of abrasives clogging pipelines and nozzles still occurs from time to time; moreover, the existing pre-mixed abrasives The water jet device cannot flexibly control the output of the high-pressure abrasive jet, and cannot perform high-precision cutting and cleaning
