Problems solved by technology

Since the paint is a viscous liquid, the effect of using the circulation pump to circulate the paint is not ideal, and the circulation speed is too slow. When the paint stays in the circulation pump for a long time, the paint is easy to condense and cause the circulation pump to block

Abstract

The invention provides a low-pressure circulating pump system for conveying paint. The low-pressure circulating pump system comprises a circulating pump and a circulating pipe. The circulating pump comprises a pump body and a motor. A feeding controller is installed on the left side of the pump body and comprises a drive motor, a worm, a connecting rod and a round piston. A worm wheel is arranged on the connecting rod and engaged with the worm, and the round piston is connected to the connecting rod. A sucking pump is installed on the right side of the pump body, an electricity box is installed in the pump body, and a transformer and a pause switch are installed in the electricity box. A first parallel branch and a second parallel branch are connected to the transformer, the drive motor is connected to the first parallel branch, and the sucking pump and the pause switch are connected to the second parallel branch. A pressure stabilizing valve and a one-way valve are arranged at the portion, on a discharge port, of the circulating pipe. An exhaust device is additionally arranged in the circulating pump, a low-pressure environment is formed in the circulating pump, the conveying rate of the paint is remarkably increased, and the working efficiency of the circulating pump is improved; and product competitiveness is improved, and the circulating pump is not prone to blockage.

Description

technical field [0001] The invention relates to a circulation pump, in particular to a low-pressure circulation pump system for conveying paint. Background technique [0002] Circulation pump refers to the pump for circulating liquid in the device for conveying reaction, absorption, separation, and regeneration of absorption liquid. Generally, a single-stage centrifugal pump is used. The flow rate of the circulation pump is medium, and under stable working conditions, the change of the flow rate of the pump is relatively small. Its low head is only used to overcome the pressure drop of the circulation system. Low head pumps can be used. The circulation pump refers to the function of the pump, and the centrifugal pump refers to the structure of the pump. The two are completely two concepts. The working principle of the circulating pump is the pump used to circulate the circulating fluid. For example, the hot water in the water heating and heating pipeline is circulated by...
