Embodiment Construction

[0015] figure 1 What is shown is a basic type of implementation, which is mainly composed of two parts: a continuous slurry supply mechanism 3 at normal pressure and a high-pressure abrasive jet diaphragm pump 1. The two parts are connected by a slurry suction pipeline 4, and the high-pressure pipeline 5 is connected between the high-pressure abrasive jet diaphragm pump 1 and the nozzle 6, and the high-pressure abrasive jet diaphragm pump 1 is also connected with the leakage liquid tank 2 and the upper replenishment liquid tank 7.

[0016] The high-pressure abrasive jet diaphragm pump 1 has a pump body 1A with two interconnected cavities. The pump body functions to withstand pressure, surround pressure chambers and support chambers, and provide installation locations for other components. Wherein, a piston 1B is arranged in one cavity, and a sealing element 1D is arranged between the sliding contact surface of the pump body 1A and the piston 1B. A flexible diaphragm 1E is fix...

Abstract

The present invention discloses a kind of open abradant-packed fluidic equipment based on high-pressure abradant fluidic diaphragm pump. It is characterized by that it includes the following several portions: spray nozzle, connection pipeline, normal-pressure slurry continuous supply device and high-pressure abradant fluidic diaphragm pump. Said equipment can be used for cutting, drilling and broaching various materials and cleaning surface of various materials.

Description

technical field [0001] The invention relates to a high-pressure abrasive (slurry) jet cleaning and cutting device, in particular to an open-type abrasive jet device based on a high-pressure abrasive jet diaphragm pump. It is suitable for cutting, drilling and surface cleaning, derusting and roughening of various materials. Background technique [0002] There are two types of existing abrasive jet generating devices: one is the post-mixing type, which uses the principle of re-jet flow to mix water and abrasive after high-pressure water jetting. The disadvantage of this method is that the abrasive is not easy to mix evenly with water, the diameter of the cutting or drilling jet is large, and the quality of the kerf is unstable and other adverse effects; in addition, the jet pressure required for cutting is relatively high, generally exceeding 70MPa , so the requirements for the high-pressure water generating device and the pressure resistance and sealing of each component in ...
