Pressureproof water pump with anti-deformation shell

Abstract

The invention relates to the technical field of water pumps, in particular to a pressureproof water pump with an anti-deformation shell. The pressureproof water pump comprises a water pump body. The water pump body comprises a pump shell. A pump spindle is arranged in the pump shell. A pump spindle rotor set is arranged on the upper portion of the pump spindle. A motor stator set is arranged outside the pump spindle rotor set and mounted on the upper portion of the inner wall of the pump shell. An impeller is arranged at the bottom of the pump spindle. A water outlet is formed in the lower portion of the left side of the pump shell. A water inlet is formed in the middle of the bottom face of the pump shell. Supporting legs are arranged on the bottom face of the pump shell. A plurality of rotary force unloading toroid shells are arranged on the pump shell. A damping base is mounted at the bottom end of the pump shell. The pressureproof water pump is convenient to use, can bear large pressure and good in pressure resistance and not prone to being deformed; force unloading faces can be formed through the rotary force unloading toroid shells conveniently when flow pressures in different direction are applied to the water pump, the pressure resistance of the pump body is improved, the effect that the pump body is not reshaped or deformed is ensured, thus, the pump body works normally, the service life of the pump body is prolonged, and maintenance of the pump body is reduced.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a pressure-resistant water pump with a deformation-resistant casing. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures and liquids containing suspended solids can also be transported. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types.

AI Technical Summary

Problems solved by technology

When traditional water pumps work in deep water areas, there are the following problems: First, due to the continuous operation of the pump body and the pressure of the water flow, the pump casing is subjected to relatively high pressure, while the traditional pump casing is single-walled, which is easy to make the pump The casing is deformed, which affects the normal operation of the components in the pump casing, resulting in a decrease in work efficiency

The second is that when the traditional pump casing works underwater, due to the uncertainty of the direction of the water flow, it will always be subjected to water flow pressure in different directions, and the traditional pump casing has no unloading components, which also makes the pump body prone to deformation. This also affects the normal work of the pump, resulting in a decrease in work efficiency.

The third is that the water pump will vibrate due to itself or water flow or other factors when it is working, while the traditional water pump does not have shock absorbing components, so it is easy to cause deformation of the pump body, thus affecting the working efficiency of the water pump
