A magnetic pulse abrasive water jet cutting machine

Abstract

The invention relates to a magnetic impulse abrasive water jet cutting machine. The water tank of the magnetic impulse abrasive water jet cutting machine is connected to a filter, a plunger pump, a stop valve and a pressure gauge in sequence through a pressure resistant rubber pipe. A safety valve is connected to the bypass, a one-way valve is connected after the plunger pump and the safety valve, the water pipe is divided into three branches after the one-way valve, the first branch is connected to the upper end of an abrasive tank, the second branch is connected to the lower end of the abrasive tank through an abrasive amount adjusting valve, an abrasive mixing device is connected to the lower end of the abrasive tank, the third branch is connected to the abrasive mixing device though a water amount adjusting valve, a magnetic impulse device is connected to the abrasive mixing device, the magnetic impulse device stretch out and is connected to a spray gun, the magnetic impulse device makes the abrasive jet generate periodic impulses, thus impulse abrasive water jet is formed, the materials are cut by the impulse abrasive water jet, which are ejected from the spray gun, and the goal of cutting operation is achieved. The magnetic impulse abrasive water jet cutting machine is suitable for cutting, surface washing and derusting of various materials.

Description

technical field [0001] The invention relates to a water jet cutting machine, in particular to a magnetic pulse abrasive water jet cutting machine. Background technique [0002] At present, water jets are widely used in cleaning, descaling, rust removal, metal and hard material cutting, grinding, etc. Pulsed abrasive jet is a new type of jet developed based on pulsed jet and abrasive jet technology. Compared with ordinary abrasive jet, the energy exchange and acceleration effect of abrasive in the state of pulsed jet is better, which is beneficial for abrasive particles to enter the jet center and improve abrasive Granular speed, better cutting or impact crushing effect. The patent application number 201110008580.5 proposes a portable abrasive water jet cutting machine for coal mines, which is used for safe cutting operations in dangerous situations such as flammable and explosive. The patent No. 201120500225.5 proposes a magnetic drive water jet device, which uses a magnet...
