Non leakage fully power closed type vertical self priming pump

Abstract

The invention relates to a no-leakage full-power sealed vertical self-priming pump, comprises a motor, a clutch, a pump holder, a pump shell, a pump axis, a blade wheel, a baffle, a pump inlet and a pump outlet, wherein the main axis of the motor is connected with the pump axis and the blade wheel via the clutch, the invention also comprises a full-power sealed device, a power gas-sealed device, a gas-liquid separating chamber, a liquid storage chamber and a guide blade gas-liquid mixing machine. The full-power sealed device is arranged on the connection position of the pump axis and the pump holder, comprising an axial power sealed device and a radial power sealed device, wherein the motor drives the full-power sealed device to rotate with high speed, and axial power sealed device produces an upward pumping effect to prevent the outside air into the pump, while the radial power sealed device produces an outward radial pumping effect to prevent the liquid in the pump leakage out of the pump and realize no-leakage full-power sealing. The self-priming pump of the invention has the advantages of reliable operation, convenient repairing, short self-priming time, high pumping efficiency, no liquid leakage, full power characteristic and meeting the saving energy and protection environmental requirements.

Description

technical field [0001] The invention relates to a vertical self-priming pump, in particular to a non-leakage full-power sealed vertical self-priming pump whose medium is water or other liquids. Background technique [0002] Self-priming pump is a pump product in fluid machinery. It is suitable for pumping sewage and clean liquid with particles. The suction pipeline does not need a bottom valve and does not need to fill the pump body with liquid when starting. It can be started directly, so it is widely used. The shaft seal of the traditional vertical self-priming pump is a mechanical seal or packing seal, which is easy to leak and damage. When the shaft seal leaks air, the pump will not be able to self-prime normally. [0003] A kind of vertical self-priming pump of prior art, its structure is as figure 1 As shown, it mainly includes two parts, the motor and the vertical self-priming pump, wherein the motor 1 is fixed on the pump frame 2, the pump body 9 is connected with t...

Problems solved by technology

[0009] The task of the present invention is to provide a non-leakage fully dynamic sealed vertical self-priming pump, which solves the problem that the vertical self-priming pump in the prior art uses mechanical seals or packing seals that are easy to damage and leak and often break down and fail to work properly. Self-priming work and increase the user's use and maintenance costs
