Self-priming jet pump, as a high-efficiency liquid conveying equipment, its more significant advantage is that it has self-priming ability, which can extract the medium from the thermal water pump, impurity filter, distillation device and other containers, and does not need to regular the required valves in the pipeline, pumping system and other equipment, effectively saving the plant area and improving the efficiency of the product process device. Next, let's understand how it works. The basic working principle of

self-priming jet pump is to use the interaction between water flow and gas flow to complete the medium transportation. In the self-priming jet pump, there are two connected throttling elements with distinct geometric shapes, the nozzle and the throat. Below the nozzle is a mixing chamber, which is called throttling phenomenon equipment. The medium is accelerated through the nozzle, and the resulting high-speed airflow causes the mouth behind the nozzle to suck the ambient gas, and the air brought back is mixed with the medium to reduce the pressure and form the self-priming effect of the pump. The self-priming depth of the

self-priming jet pump is generally 3m, and the self-priming depth can be increased by increasing the number of design plates. The self-priming jet pump has the characteristics of compact structure, light weight, high reliability and easy operation. Its technical performance and service life are relatively stable, do not require a lot of maintenance, low operating costs, and are widely used. Especially in some areas where liquid transportation requires a large head, such as petrochemical and chemical industries, self-priming jet pumps are popular because of their compact structure, strong self-priming ability, high efficiency and stability.

Of course, it is also necessary to pay attention to the selection of self-priming jet pumps should be selected according to different media and different conditions to achieve the best results. At the same time, we also need to pay attention to the use conditions of the self-priming jet pump. When selecting the pump, we should start with the flow, head and other parameters, equipped with appropriate motors and braking devices, and do maintenance and maintenance for process conditions.

self-priming jet pump has unique advantages in conveying medium, its self-priming ability and high efficiency can be used as one of the reference elements when selecting conveying equipment. I hope this article will help you to choose and understand the working principle and advantages of self priming jet pump, so as to contribute to the overall efficiency of your liquid delivery system.
