Description

Radio Control Unit for Handheld Premixed Abrasive Waterjet Equipment

technical field

The utility model belongs to the technical field of abrasive water jets, in particular to a radio control device for hand-held front-mixing abrasive water jet equipment.

Background technique

Abrasive waterjet technology is an unconventional cutting technique that emerged in the 1980s. Abrasive water jet technology has the outstanding advantage of being able to cut any high-strength and high-hardness materials without generating heat. Abrasive waterjet is divided into post-mixing and pre-mixing abrasive waterjet according to whether the abrasive and high-pressure water flow are mixed in the nozzle. Wherein, the nozzle and the mixing chamber of the pre-mixed abrasive water jet are independent, and the abrasive and the high-pressure water flow are mixed in the mixing chamber before reaching the nozzle. The structure of commonly used pre-mixed abrasive water jet equipment is shown in Figure 1.

Specifically, the formation process of the pre-mixed abrasive water jet is as follows: the high-pressure water flow formed by the high-pressure water pump 2 is divided into two parts after passing through the manual cut-off valve 4, and one part is initially mixed with the abrasive in the abrasive tank 5. The valve 6 is mixed with another part of the high-pressure water flow in the mixing chamber 7 to form an abrasive water flow. The abrasive water flow is sent to the spray gun 9 through the high-pressure hose 8, and is accelerated by the nozzle 10 at the front end of the spray gun 9 to form an abrasive water jet. Due to the high mixing efficiency of the pre-mixed abrasive water jet, its working pressure is only 1/7-1/10 of that of the post-mixing, so the volume of the equipment is greatly reduced. Moreover, the front-mixed abrasive water jet can mix abrasives and water flow in the back field of work, and then transport them to the front field of work through a high-pressure hose with a length of more than hundreds of meters, and the spray gun can be operated manually, which greatly improves the device. Use of maneuverability. Therefore, the hand-held pre-mixed abrasive water jet equipment is very suitable for use in wild and dangerous environments.

The working state of the hand-held pre-mixed abrasive water jet equipment includes: spraying state and stop spraying state, and the spraying state is further divided into the state of spraying abrasive water jet and the state of spraying pure water jet. For the hand-held pre-mixing abrasive waterjet equipment, the substances conveyed in its high-pressure hose and spray gun include abrasive water flow, and the abrasive water flow will quickly wear the control valve core, so the foot control valve on the high-pressure hose or The gun valve on the spray gun is used to control the equipment, and the method of spraying or stopping the spraying state is not practical. At present, the method used to control the working state of the hand-held pre-mixed abrasive water jet equipment is: by opening or closing the manual shut-off valve 4, to control the spraying or stopping of the spraying state of the equipment; to open or close the manual shut-off valve 6 to control the injection. Water jet or pure water jet. The manual shut-off valve 4 and the manual shut-off valve 6 involved in this method are both located in the back field of work and are manually operated, so it is very inconvenient for the operator to control in the front field of work, which reduces the work of the hand-held front-mixing abrasive water jet equipment. efficiency.
