Small gasoline engine self-priming pump, household self-priming pressurized water pump

1. Introduction to Small Gasoline Engine Self-priming Pumps

The QZB portable small gasoline engine self-priming pump is mainly composed of two major parts: a gasoline engine and a self-priming pump. It adopts a high-end two-stroke engine to ensure good combustion economy. The pump body is made of brand-new aluminum alloy, with cast iron impeller and turbine cover, which greatly improves the durability of the water pump. The standard PF threaded interface has strong versatility and can be configured with water pipes of different models. The full-frame protection ensures the reliability of the water pump when operating in harsh conditions. It is widely used in various industries such as factories, agricultural irrigation, construction, greening watering and other working conditions. It is especially suitable for working occasions without power supply such as wild areas, and can also be used as a standby pump to deal with emergencies such as power outages.

2. Structural Principle of Small Gasoline Engine Self-priming Pumps

The QZB portable small gasoline engine self-priming pump is a type of centrifugal pump. The working principle of a centrifugal pump is that when the pump is filled with water, the engine drives the impeller to rotate, thereby generating centrifugal force. The water in the impeller grooves is thrown to the periphery and flows into the pump casing under the action of centrifugal force, so the pressure at the center of the impeller decreases. This pressure is lower than the pressure in the water inlet pipe, and water flows into the impeller from the suction pool under the action of this pressure difference. In this way, the water pump can continuously absorb water and supply water continuously.

4. Usage Characteristics of Small Gasoline Engine Self-priming Pumps

1. It can start and run by adding gasoline, without worrying about being unable to use due to power outages. It is especially suitable for occasions without power supply, or as an emergency standby pump.

2. It adopts a direct-connected structure, and the pump head is made of aluminum alloy. It has the advantages of small size and light weight, and can be moved conveniently. According to user needs, four wheels can be added under the body, or it can be directly installed on a trolley, which further improves the portability and mobility.

3. The ultimate self-priming height can reach 8 meters, and the self-priming water feeding time is short. The portable small gasoline engine self-priming water pump has low vibration and low noise during operation.

4. A protective bracket is installed on the outer periphery of the body, which is easy to install and use. When in use, it only needs to be placed on a flat ground and fixed slightly to run.

5. It adopts a semi-open impeller, which has sewage discharge capability. It can not only pump clean water, but also pump river water containing a certain amount of sediment from rivers.
