A Quick Start Device Applied to Centrifugal Pump

Abstract

The invention provides a quick start device applied to a centrifugal pump, which comprises an upper self-priming chamber, a lower self-priming chamber and an inlet pipeline arranged sequentially from top to bottom, and the upper self-priming chamber and the lower self-priming chamber are integrally installed on the inlet pipeline On the axis of the upper self-priming chamber, there is a main shaft and a hexagonal partition rotatably installed on the main shaft. The blade top of each partition is closely attached to the inner wall of the upper self-priming chamber. There are three identical shrinking grooves on the inner side, each of which is equipped with a spring and a separation baffle, each shrinking groove is equipped with an exhaust hole on one side, and an air suction pipe on the other side, and the exhaust hole is connected to the atmosphere , the suction pipe communicates with the upper self-suction chamber and the lower self-suction chamber, and the lower self-suction chamber is provided with a spring-connected upper check valve and a lower check valve. The quick start device of the present invention realizes that the centrifugal pump can directly enter the normal operating condition when it is started without water, and the hexagonal baffle can complete eighteen times of inhalation and exhaust process after one rotation, which can significantly improve work efficiency and greatly simplify operation process.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a quick start device applied to centrifugal pumps. Background technique [0002] Centrifugal pumps are widely used in agricultural irrigation, fire fighting and disaster relief and other fields. However, when the centrifugal pump is just started, it is necessary to discharge the air in the pump and the pipeline first. When the pump is idling, the bearing components emit heat. Long-term idling operation will reduce the service life of the pump and damage the components of the centrifugal pump. Therefore, the centrifugal pump often needs to be started by irrigation, which greatly prolongs the start-up time and seriously restricts the working efficiency of the centrifugal pump. The external auxiliary vacuum pump not only causes loud noise, but also makes the transportation of the whole unit difficult, reduces the overall mobility, and is equipped with at least two motors,...

Problems solved by technology

Therefore, the centrifugal pump often needs to be started by irrigation, which greatly prolongs the start-up time and seriously restricts the working efficiency of the centrifugal pump.

The external auxiliary vacuum pump not only causes a lot of noise, but also makes the transportation of the whole unit difficult, reducing the overall mobility, and supporting at least two motors, which increases energy consumption
