[Chemical Knowledge]：The principle of self-priming pumps-uncovering the mystery of liquid delivery

Self-priming pump is a kind of pump that sucks liquid and transports it to a higher place. It is widely used, especially in the fields of agriculture, construction, municipal administration and petrochemical industry. The self-priming pump is composed of a wind water tank, a pump body, a compression chamber, a diaphragm, an outlet pipe and a suction pipe. Its working principle is similar to the takeoff and landing of an aircraft. The working principle of the

self-priming pump is based on the interesting phenomenon of vacuum suction. When the self-priming pump starts to work, it first uses its own pressure to bring the liquid to the pump. At the same time, the compression chamber is continuously pressurized to push out the high-speed liquid to form a suction force. Under the action of the suction pipe, the liquid will be continuously sucked out.

When the liquid leaks, the fluid forms its own pressure in the wind water tank, so that the pump eliminates all gas and air. At this time, the diaphragm forms a barrier between the high pressure and the low pressure, so that the liquid always keeps circulating in the pump body. Next, the diaphragm continues to act, so that the pressure of the outlet pipe gradually increases, and then the liquid pressure is transported out.

, it is important to note that the self-priming pump must be used in accordance with the correct maintenance guidelines and installation requirements. If the self-priming pump is not installed on a stable base, the pump will vibrate and cause abnormal noise. During maintenance, we must also pay attention to whether the separator is blocked, whether there is leakage in the suction pipe and the outlet pipe. Otherwise, the pump can be blocked by bubbles, plugs, etc., and suddenly stop using or cause safety hazards. The principle of

self-priming pump is vacuum suction, which is a simple and efficient pump. In addition to industrial work, it is also widely used in domestic water supply and urban water supply and drainage systems. For users who use self-priming pumps, its maintenance and maintenance should receive enough attention and attention to ensure its normal operation or replace defective products.
