Scaling powder fluid pressure control device

Abstract

The invention discloses a scaling powder fluid pressure control device which comprises a pressure stabilizing pump box, a defoaming valve set and an active conveying assembly, a conveying cavity is formed in the pressure stabilizing pump box, the surface of the pressure stabilizing pump box is provided with an inlet end and an outlet end which are communicated with the interior of the conveying cavity, and a driving motor is fixedly installed on one side of the pressure stabilizing pump box; the output end of the driving motor is fixedly sleeved with a driving gear sleeve located in the conveying cavity. According to the invention, the active pressure compensation structure is arranged, and the pressure stabilizing pump box and the active conveying assembly are used for isolating and blocking liquid flow movement at two ends, so that mutual influence of pressure of liquid flows at two ends is avoided; positive pressure pushing of liquid flow is conducted through constant-speed movement of the driving motor by means of cavity changes between the driving conveying assembly and the inner wall gap of the pressure stabilizing pump box, so that the fluid pressure at the scaling powder outlet end is kept constant, and pressure control can be achieved by adjusting the power rotating speed of the driving motor.

Description

technical field [0001] The invention relates to the technical field of welding processing, in particular to a flux fluid pressure control device. Background technique [0002] Welding, also known as welding or welding, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metal or other thermoplastic materials such as plastics. In the soldering process, flux helps and facilitates the soldering process while protecting and preventing oxidation reactions. In the prior art, the supply of flux is based on the action of gravity and flows to the nozzle through the pipe, and then the flux is sprayed out from the nozzle. Due to factors such as impurities or pipe bending, the flux flow will be unstable, which will lead to poor welding and seriously affect the welding quality.

Due to factors such as impurities or pipe bending, the flow of flux will be unstable, which will lead to poor welding and seriously affect the welding quality

[0003] The existing flux delivery pipeline structure mainly uses impeller pumps, plunger pumps or other mechanical pumps for direct supply and delivery. Due to various factors in the pipeline, it is easy to cause changes in the delivery pressure, resulting in fluctuations in the flux jet flow at the outlet. The flux jet cannot be precisely aimed at the welding surface, which affects the welding quality. In addition, in the process of flux pumping, the gas in the flux is often mixed, resulting in sputtering of the flux at the outlet and cannot be accurately supplied to the welding surface, and the existence of gas It mainly appears in the form of large bubbles. When the gas moves to the outlet section, the short-term supply of flux is suspended and the welding quality is affected. There are certain defects.

[0004] In view of this, the existing problems are studied and improved, and a flux fluid pressure control device is provided to solve the current problem of unstable flux delivery fluid pressure and poor soldering quality caused by interference of air bubbles inside the flux. Through this technology, the purpose of solving problems and improving practical value is achieved
