In today's rapid development of science and technology pattern, many traditional equipment can not fully meet the needs of market work, especially in a variety of irrigation and drainage systems, the average tool can not afford this pressure, but if not in time Addressing irrigation and drainage issues affects not only the progress of work, but also the often negative impact on the environment. Under many pressures, automatic self-priming pump spontaneously, then let me introduce the introduction of such products, first of all from the working principle of self-priming pump: Automatic self-priming pump works Self-priming pump principle of water absorption Is started after the self-priming pump, self-priming pump impeller by rapid rotation of the self-priming pump fluid swirling flow, the self-priming pump impeller population at the air volume into the pump chamber, mixed with water to form Foamy gas-liquid mixture. Due to the centrifugal force of the self-priming pump impeller rotating, the gas-liquid mixture constantly throws out and flows along the volute of the self-priming pump. Since the self-priming pump has a very small gap between the pump tongue and the impeller, it will act as a barrier to the mixture, so a significant portion of the mixture will be sent along the inner passage to the drain. In the discharge port has a wide air-water separation chamber, so the mixture into the gas-water separation chamber, the flow rate will slow down. And because of the difference between the gas and the liquid, the lighter gas is separated and exhausted, discharged from the drainage pipe and the exhaust pipe. The degassed medium flows back to the inlet of the impeller along the outer passage of the pump body due to the large specific gravity, and is again entrained in the air to form a mixed liquid. So many times the cycle back and forth, after a certain period of time can be self-priming pump inlet air discharge to reach a certain degree of vacuum. At this point in the liquid under the action of atmospheric pressure and negative pressure pump, the liquid is sucked into the liquid pipe, self-priming pump to play a role in absorbing water. Self-absorption process is completed, then automatically converted to the process of delivery, the media kept sending. Normal water, self-priming pumps both inside and outside the channel automatically into the water channel. Automatic self-priming pumps are generally done in the pump body special treatment, which uses a double volute and gas-water separation device, this structure is more complex than the traditional pump equipment, it can achieve the best effect is to save a lot of Plus the added time and power consumption, the traffic is relatively large, relatively stable working pressure and fewer faults, the work is very reliable. So automatic self-priming pump can play a great role in a large number of irrigation systems.
