Automatic pump self-priming pump is not one of the common failures, but also the pump often encountered in daily use of the problem, then when faced with pump water, we know where the reason? If you do not know, then we will introduce Xiaobian self-priming pump does not absorb the reasons. Secret self-priming pump does not absorb the reasons for the water First, the flow of water out of the resistance loss is too large When the pipe is too long, too many corners, or the pump into the tube diameter and some other details, will cause the water flow in the pipeline Resistance loss is too large. Second, the pump speed is too low (1) power machine maintenance does not record. (2) improper installation. (3) the pump itself mechanical failure. (4) belt wear. (5) Human factors. Third, the suction is too large Pump suction port to establish the degree of vacuum is limited, the centrifugal suction pump suction is generally between 3 to 8.5 meters, not only when installing the pump is simple and convenient. Fourth, the air inlet and the pump body air (1) cracks in the inlet pipe cracks, inlet and pump connections appear tiny gaps, are likely to make the air into the water pipe. (2) The packing of the pump is worn or the pressure of the packing is too loose due to the long-term use, resulting in a large amount of water being ejected from the gap between the packing and the shaft sleeve of the pump. As a result, the external air enters the pump from these gaps, Affected the mention of water. (3) The horizontal section of the inlet pipe in contact with the pump applies a descending gradient of 0.5% or more to the direction of the flow of water, and the end connected to the pump inlet shall be the highest, not to the full level. If you tilt up, there will be trapped air inlet pipe, reducing the vacuum hose and pump, affecting water absorption. (4) Inlet pipe Due to long-term potential underwater, pipe wall corrosion holes, water pump work continues to decline, when these holes exposed water, the air from the hole into the water pipe. (5) Some users did not fill enough water before the pump was started; sometimes the seeped water overflowed from the vent, but the air was completely discharged without rotating the pump shaft, leaving a little air to remain in the intake pipe or pump body . Fifth, the impact of other factors (1) the leakage of export pipe will also affect the amount of water. (2) Gate valve or check valve malfunction or blockage will result in reduced flow or even pumping out the water. (3) the bottom valve filter is clogged; or the bottom valve causes potential clogging of the filter in the sludge layer. (4) impeller wear serious. Impeller blades worn by long-term use, affecting the pump performance. (5) Bottom valve can not be opened. It is usually due to the pump being left on for too long, the bottom valve gasket is stuck, and the bottom valve without gasket may rust. In summary, self-priming pump is not self-priming pump where the reason, in daily life, if you use the pump, and then encounter the problem of non-absorbent pump, you can refer to the above reasons to find a solution.

The liquid inlet/outlet adopts a ceramic hard seal structure, the liquid is in contact with the ceramic throughout the entire process, and does not touch the stainless steel jacket. The ceramic parts of the liquid inlet/outlet can be disassembled for cleaning and disinfection like the ceramic plunger rod and the ceramic reversing rod, which completely solves the problem of cleaning the dead angle between the steel jacket and the ceramic.
