Compound water pump

Abstract

The invention provides a compound water pump. A motor and a pump body are movably mounted in a rectangular frame body; rotating drums are movably mounted on the outer surface of one side of the motor;a rotating shaft is movably connected between the rotating drums and the motor; first limiting drums are fixedly mounted in each rotating drum near the center and the upper end of one side; and the two rotating drums are mounted up and down. The compound water pump is convenient to disassemble and adjust, regular manual cleaning of the internal of the pump body is conducted to keep the water clean, and the compound water pump can properly adjust the water pumping speed according to operation demands; secondly, the angle can be adjusted to maintain main parts of a machine body, and the heightsof the motor and the pump body are increased to reduce contact between the motor and the pump body and the ground, so that the use in a humid environment is convenient, and the damage is reduced; thirdly, the device is protected, and meanwhile, the heat dissipation and the ventilation can be kept; and finally, a shunting pipe can relieve the discharge pressure of single pipe orifice, so that thedischarge speed is accelerated, and the support in connection between a water outlet and an external pipe is convenient.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a compound water pump device. Background technique [0002] With the development of the water system in various fields such as dust removal, cooling, fire extinguishing, seawater desalination, etc., the power source in the water system, that is, the development of the water pump is becoming more and more diversified. There are axial piston pumps and pumps that can meet higher pressure requirements. Reciprocating water pumps: Axial piston pumps can provide higher pressure and less pulsating impact, but axial piston pumps have more components, higher matching requirements, more difficult processing, and more expensive costs, and the plunger pumps It has high requirements on the medium and poor anti-pollution ability; the reciprocating pump has the advantages of high pumping pressure, good suction performance, high efficiency, and adaptability to a wide range of conveying media....

Problems solved by technology

[0002] With the development of the water system in various fields such as dust removal, cooling, fire extinguishing, seawater desalination, etc., the power source in the water system, that is, the development of the water pump is becoming more and more diversified. There are axial piston pumps and Reciprocating water pump: Axial piston pump can provide higher pressure and less pulsating impact, but the axial piston pump has many components, high matching requirements, difficult processing, and expensive cost, and the piston pump It has high requirements on the medium and poor anti-pollution ability; the reciprocating pump has the advantages of high pumping pressure, good suction performance, high efficiency, and adaptability to a wide range of conveying media.

[0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: 1. The compound water pump frequently reverses direction during the working process, resulting in a large hydraulic shock. In areas with high altitudes, the air pressure is lower. The smaller the suction of the pump, the less the pumping speed is adjusted in time, and it cannot adapt to the operation requirements well. In addition, its fixed structure is inconvenient to disassemble and assemble, and the inside of the pump body is easy to accumulate scale, which is inconvenient to clean; 2. Generally, the pump is used in a humid environment and directly touches the ground , without protection, the parts will be damaged by moisture; 3. The water pump generally works outdoors, and the body is exposed and easily damaged, but if it is all wrapped up, it will cause poor heat dissipation and the machine will become hot; 4. The general water outlet is single, and the water flow is excessive. , the single port cannot be discharged well, which affects the water outlet speed
