Embodiment 1

[0040] see Figure 1~2 As shown, the embodiment of the present invention provides a pre-mixed water jet system, which includes a water tank 1, a high-pressure water source drive device 2, an abrasive tank 3, an abrasive mixing device 4, a spray gun 5 and a control device 6; wherein the water tank 1 is used to supply water to the system.

[0041] The high-pressure water source driving device 2 includes a pump 20 and a motor 21 that drives the pump 20, and the pump 20 is connected to the water outlet of the water tank 1, and an overflow valve 22 is connected in parallel on the pump 20, and the overflow The inlet of the valve 22 is connected to the water outlet of the pump, the overflow valve 21 is used to adjust the maximum working pressure of the system, and the water outlet of the pump 20 is also connected to a pressure for displaying the water outlet pressure of the pump 20 Table 22. Specifically, the pump 20 is a plunger pump, and the motor 21 is a permanent magnet motor. T...

Embodiment approach

[0051] The cutting implementation method of the embodiment of the present invention is as follows:

[0052] Step 01: Turn on the energy device 7, power on the sensor 51, the control device 6, and the motor 21, turn on the control device 6 and place the motor 21 in a waiting state;

[0053] Step 02: Hold the spray gun 5, open the operation part 50, increase the displacement of the operation part 50 to adjust the induction signal of the sensor 51 so that the speed of the motor 21 rises to the working speed, and at the same time adjust the overflow valve 22 so that the pump 20 is connected The indication value of the pressure gauge 23 reaches the preset system flushing pressure value;

[0054] Step 03: Aim the nozzle of the spray gun 5 at the object to be cut for cleaning. After cleaning, reduce the displacement of the operation part 50 to adjust the induction signal of the sensor 51 so that the speed of the motor 21 gradually decreases until it stops;

[0055] Step 04: Hold the...

Abstract

The invention discloses a pre-mixing water jetting system. The pre-mixing water jetting system comprises a water tank, a high-pressure water source driving device, a grinding material tank, a grindingmaterial mixing device, a spraying gun and a control device; the high-pressure water source driving device comprises a pump and a motor used for driving the pump, and the pump is connected with a water outlet of the water tank; the grinding material tank is connected with the pump and used for storing grinding materials; the grinding material mixing device is connected with the pump and the grinding material tank and used for mixing the grinding materials with water delivered by the pump; the spraying gun is connected with the grinding material mixing device and provided with an operation portion, the operation portion is connected with a sensor, and the sensor is used for detecting the displacement of the operation portion; and the control device is used for receiving displacement data of the sensor and controlling the rotation speed of the motor, and the larger the displacement is, the higher the rotation speed of the motor is. According to the pre-mixing water jetting system, the rotation speed of the motor is controlled through the sensor installed on a spraying gun body, and it is guaranteed that the water jetting speed and the cutting capability are controlled in the whole process.

Description

technical field [0001] The invention relates to the technical field of cold cutting, in particular to a pre-mixing water jet system. Background technique [0002] Jet cutting is the only cold cutting technology at present. It has the characteristics of no high temperature, no spark, and no pollution. It is suitable for emergency rescue and military use in flammable, explosive or special environments such as underwater, traffic accidents, coal mines, and petrochemicals. Waterjet cutting originated in the 1980s. It first served aviation and aerospace special processing. In the industrial sector, at present, industrial applications are mainly concentrated in the traditional water jet field. [0003] Domestic patent 201310363029.1, the invention describes a magnetic pulse abrasive water jet cutting machine, the water tank is connected to the filter, plunger pump, stop valve, and pressure gauge through pressure-resistant hoses in sequence, and the bypass is connected with a safe...
