Gas liquid mixed self-priming pump

1、 Product Introduction

The gas-liquid mixed self-priming pump can be used as an air flotation device, so it is also called a floating pump. Ordinary self-priming pumps may experience cavitation after sucking in gas, but this type of air flotation self-priming pump can suck in 10% of gas without cavitation. The material of the gas water mixed self-priming pump is uniformly made of stainless steel, which can transport corrosive media.

2、 Product principle

Before starting the water pump, fill the pump casing with water (or if there is water inside the pump casing itself). After starting, the high-speed rotation of the impeller causes the water flow in the impeller channel to flow towards the vortex shell. At this time, a vacuum is formed at the inlet, causing the inlet check valve to open, and the air in the suction pipe to enter the pump and reach the outer edge through the impeller channel. On the other hand, the water discharged into the air-water separation chamber by the impeller flows back to the outer edge of the impeller through the left and right return holes. The water flowing back from the left return hole is directed into the impeller channel under the action of pressure difference and gravity, and is crushed by the impeller. After mixing with the air from the suction pipeline, it is thrown towards the volute and flows in the direction of rotation.

Then it merges with the water flowing from the right return hole and flows along the snail shell. Due to the continuous impact of the liquid on the blades inside the snail shell, it is constantly shattered by the impeller and strongly mixed with the air, generating a mixture of gas and water that flows continuously and cannot be separated. The mixture is stripped off by the tongue at the outlet of the snail shell and enters the separation chamber along the short tube. The air in the separation chamber is separated and discharged through the outlet pipe, while the water still flows towards the outer edge of the impeller through the left and right return holes and mixes with the air in the suction pipe. Repeat this process repeatedly, gradually exhausting the air in the suction pipeline and allowing water to enter the pump, completing the self-priming process.

3、 Product Features

1. Exquisite volume and high performance, achieving miniaturization of industrial equipment.

2. The combination of components made of ultra precision and advanced materials is suitable for a wide range of liquids and applications, with low corrosion resistance and low NPSH margin, and stable performance without liquid leakage.

3. There is no mechanical friction inside the pump except for the contact surface of the mechanical shaft seal, and the performance remains stable for a long time without failure.

4. Low noise, long lifespan, greatly improving the reliability of the device.

5. On site maintenance is easy to operate and maintains the interests of users.

4、 Application scope

1. It can be used as air flotation treatment equipment, ozone water production equipment, oxygen enriched water production pump equipment, and biochemical treatment equipment.

2. Can serve as a heat medium for various temperature regulating devices The refrigerant circulates and moves.

3. Can be used as a matching pump for various filtering devices.

4. Low viscosity liquids such as gasoline, diluent, and various volumes can be attracted or transferred under high pressure from underground storage tanks.

5. It can also be used for spray treatment of clean water, pure water, food, chemical liquid, waste liquid, etc.

6. It can also be used in special environments that require frequent starting and stopping, are prone to water hammer, and experience rapid changes in back pressure. For example, small steam boilers, high-rise water supply, high-pressure water injection into high-pressure tanks, suction from vacuum negative pressure tanks, etc.

7. It is possible to extract water samples from rivers or water storage tanks, transport foaming liquids, and deliver liquids through long horizontal pipelines that are prone to gas vortices.

5、 Precautions

1. The purpose of producing ozone water is generally selected directly based on the flow rate of the water pump.

2. Dissolved air flotation and other applications generally require consideration of the proportion of backflow water (usually 10-50% of the treated water) based on the water quality.
