Description

Vertical self-priming pump

Technical Field

The utility model relates to a self priming pump technical field specifically is a vertical self priming pump.

Background

The self-priming pump belongs to a self-priming centrifugal pump and has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, stronger self-priming capability and the like. The pipeline does not need to be provided with a bottom valve, and only quantitative liquid guiding is required to be ensured to be stored in the pump body before work. Different liquids can adopt self-priming pumps made of different materials.

The self-priming pump has the working principle that before the water pump is started, the pump shell is filled with water. After the impeller is started, the impeller rotates at a high speed to enable water in the impeller channel to flow to the volute, at the moment, the inlet forms vacuum, the water inlet check valve is opened, and air in the suction pipe enters the pump and reaches the outer edge through the impeller channel. Self-priming pumps are of many types of construction, with molten salt pumps, vacuum pumps, submerged pumps, metering pumps, gear pumps, corrosion-resistant pumps, acid-resistant pumps, and fire pumps flowing in the direction of rotation. Then the water is converged with the water flowing from the right water return hole and flows along the volute. The liquid continuously impacts the blade grid in the volute and is continuously crushed by the impeller, so that the liquid is intensively stirred and mixed with air to generate a gas-water mixture, and the gas-water mixture continuously flows to cause that gas and water cannot be separated. The mixture is stripped by the baffle at the outlet of the volute and enters the separation chamber along the short pipe. In the separation chamber, the air is separated and discharged through the outlet pipe, and the water flows to the outer edge of the impeller through the left and right return holes and is mixed with the air in the suction pipe. The circulation is repeated, air in the suction pipeline is gradually exhausted, water enters the pump, and the self-suction process is completed. The self-priming pump oil pump of the sewage pump, the diaphragm pump, the screw pump, the gear pump and the oil pump are the same, and the difference is that return water does not flow to the outer edge of the impeller but flows to the inlet of the impeller. When the internal mixing type self-priming pump is started, a reflux valve at the front lower part of the impeller needs to be opened, so that liquid in the pump flows back to an inlet of the impeller. The water is mixed with the air from the suction pipe under the action of the high-speed rotation of the impeller to form an air-water mixture which is discharged to the separation chamber. Where the air is exhausted and the water is returned from the return valve to the impeller inlet. The operation is repeated until the air is exhausted.

Current self priming pump is all horizontal, and it is comparatively troublesome to remove, and the pump body receives the damage extremely easily.
