Turbine Self-priming Water Pump

For ordinary centrifugal water pumps, if the suction liquid level is below the impeller, it should be filled with water before starting, which is very inconvenient. In order to store water in the pump, a bottom valve is required at the inlet of the suction pipe. When the pump is working, the bottom valve causes a great hydraulic loss. The Turbine Self-priming Water Pump does not need to be filled with water before starting. After a short period of operation, the pump itself can suck up the water and put it into normal operation.

Ⅰ. Applications of Turbine Self-priming Water Pump

1. Suitable for urban environmental protection, construction, fire protection, chemical industry, pharmaceuticals, dyes, printing and dyeing, brewing, electric power, electroplating, papermaking, industrial and mining washing, equipment cooling, etc.

2. It is suitable for clean water, sea water, chemical medium liquid with acidity and alkalinity, and slurry with general paste (medium viscosity <100 centiper, solid content up to 30%).

3. Turbine Self-priming Water Pump can be used with any filter press of any model and specification. It is the most ideal matching pump type for filter press when the slurry is sent to the filter press.

Ⅱ. Turbine Self-priming Water Pump working principle and performance characteristics.

The Turbine Self-priming Water Pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, just make sure that the pump body has a quantitative priming liquid before work. Different liquids can use self-priming pumps of different materials.

Ⅲ. The working principle of Turbine Self-priming Water Pump

Ordinary centrifugal pump, if the suction liquid level is below the impeller, it should be filled with water before starting, which is very inconvenient. In order to store water in the pump, the inlet of the suction pipe needs to be equipped with a bottom valve. When the pump is working, the bottom valve causes a great hydraulic loss. The so-called self-priming pump does not need to be filled with water before starting (the first time after installation, it still needs to be filled with water). After a short period of operation, the pump itself can suck up the water and put it into normal operation. Self-priming pumps are divided into the following categories according to the principle of action:

Gas-liquid mixing type (including internal mixing and external mixing);

2. Water ring wheel type;

3. Jet type (including liquid jet and gas jet). The working process of the gas-liquid hybrid self-priming pump: Due to the special structure of the self-priming pump body, after the pump stops, there is a certain amount of water in the pump body. After the pump is restarted, the air and water in the pipeline are sucked due to the rotation of the impeller. It is fully mixed and discharged to the gas-water separation chamber. The gas in the upper part of the gas-water separation chamber overflows, and the water in the lower part returns to the impeller, and remixes with the remaining air in the suction pipe until all the gas in the pump and suction pipe is discharged. Suck and pump normally. The water ring wheel self-priming pump combines the water ring wheel and the water pump impeller in a shell, and uses the water ring wheel to discharge the gas to realize self-priming. When the pump is working normally, the channel of the water ring wheel and the water pump impeller can be blocked by the valve, and the liquid in the water ring wheel can be discharged. The jet self-priming pump is a combination of a centrifugal pump and a jet pump (or ejector). It relies on a jet device to create a vacuum at the nozzle to achieve suction.
