Novel water pump

Abstract

The invention relates to a novel water pump, which comprises a base, a motor and a pump body, wherein the motor and the pump body are welded on the base; the top and the right side surface of the pumpbody are provided with a water outlet and a water inlet, respectively; the right end surface of the motor is fixedly connected with a rotating shaft; the left end surface of the motor is fixedly connected with a heat dissipation cover; a wheel disc is arranged in the pump body; uniformly distributed raised square blocks are welded to the circumferential surface of the wheel disc; blades which arein one-to-one correspondence with the raised square blocks are fixedly connected to the circumferential surface of the wheel disc; each blade comprises an arc-shaped blade and a straight blade; eacharc-shaped blade comprises a straight part and an arc-shaped part; each blade comprises an alloy steel substrate at the inner layer and a ceramic wear-resistant and corrosion-resistant layer at the outer layer; a wear-resistant coating coats the inner wall of the pump body; and the upper base is fixedly connected with the lower base through a soft rubber column. The novel water pump not only has high working efficiency, and but also has good heat dissipation, a good anti-vibration effect, a long service life and low cost.

Description

technical field [0001] The invention relates to the technical field of water pump equipment, in particular to a novel water pump. Background technique [0002] Water pump is a kind of equipment for conveying liquid or pressurizing liquid, which is widely used in the conveying process of liquids such as water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. A conventional water pump impeller generally includes a base, a motor, a pump body, a wheel disc and blades. The motor is the power source of the water pump. However, when the motor is running for a long time, if the heat dissipation effect is not good, it is easy to cause the motor to heat up too quickly, which not only affects the normal operation of the motor operation, and it is easy to reduce the service life of the motor; at the same time, the existing water pump blades are generally straight blades, which are simple in structure and low in cost, but have poor fluidity and large flow loss, resulting i...

Problems solved by technology

A conventional water pump impeller generally includes a base, a motor, a pump body, a wheel disc and blades. The motor is the power source of the water pump. However, when the motor is running for a long time, if the heat dissipation effect is not good, it is easy to cause the motor to heat up too quickly, which not only affects the normal operation of the motor operation, and it is easy to reduce the service life of the motor; at the same time, the existing water pump blades are generally straight blades, which are simple in structure and low in cost, but have poor fluidity and large flow loss, resulting in extremely low pump efficiency. The blades are prone to bend or wear under the impact of liquid, which will cause the pump to fail to work normally and reduce the service life of the pump; in addition, when the pump is working, the vibration generated by the motor running will cause the mechanical parts of the pump to wear and shorten the life of the pump. service life
