Why Does The Slurry Pump Not Discharge Water? Find The Reason Here

　　Why doesn’t the slurry pump come out?Come here to find the reason. Recently, I received feedback from many customers asking why the slurry pump cannot produce water.Then the editor sorted out the reasons why the slurry pump cannot produce water. I hope it can help you. Let’s take a look next!1. There is air in the water inlet pipe and pump body (1) There is no sufficient water filling before the slurry pump starts, and a small amount of air remains in the pump chamber.(2) When the slurry pump is used for installation, a slope of more than 0.5% is applied to the horizontal section of the water inlet pipe in contact with the pump against the direction of the current flow. One end connecting the inlet of the water pump is the highest, and it is not horizontal.If raised upwards, air will remain in the inlet pipe, reducing the vacuum in the water pipe and the water pump, affecting the slurry suction.(3) The filler of the slurry pump has been worn out due to long-term use or the filler is too loose, causing a large amount of slurry to be ejected from the gap between the filler and the pump shaft sleeve. As a result, external air enters the inside of the pump from these gaps, affecting the upsuspended suction.(4) The water inlet pipe is lurking underwater for a long time, and holes appear on the pipe wall. After the water pump works, the water surface continues to drop. When these holes are exposed to the water surface, the air enters the civil inlet pipe from the holes.(5) Small cracks in the pipeline, and slight gaps appear at the connection between the water inlet pipe and the water pump, which may cause air to enter the water inlet pipe.2. The speed of the slurry pump is too low (1) Artificial factors.Some users of some departments randomly equipped with another motor due to damage to the original distribution motor, which resulted in the consequence of small flow, low head, or even no water supply.(2) The impeller of the slurry pump moves more often, directly rubs with the pump body, or damages the bearing.3. The suction range is too large. Some water sources are deeper, and some water sources have flat outer terrain, and the allowable suction range of the water pump is ignored, which results in the result of less water absorption or no water absorption at all.The vacuum degree that can be established at the water suction port of the slurry pump is limited. The vacuum suction range is about 10 meters high in the water column, and the vacuum that the slurry pump cannot establish.Moreover, if the vacuum is too large, it will easily vaporize the water in the pump, making the slurry pump unfavorable.Therefore, the installation of the slurry pump must be within the maximum allowable suction range, and it must not be convenient and simple when installing the pump.4. The resistance loss in the water flow in and out of the water pipe is too large. Some users can measure it. Although the vertical interval between the reservoir or water tower and the water surface of the water source is slightly smaller than the pump head, the water lift amount is still small or the water cannot be lifted.The reason is often that the pipeline is too long, the water pipe bends are often used, and the water flow is too much in the resistance loss in the pipeline.The reason is often that the pipe is too long, the water pipe bends are many, and the water flow loses too much resistance in the pipe. In addition, some users also use slurry pumps to enter and exit the pipes at will, which also has a certain impact on the head.5. Influence of other factors (1) The bottom valve cannot be opened.Usually because the pump is shelved for too long, the bottom valve washer is stuck to death, and the bottom valve without the washer may rust.(2) The filter mesh of the bottom valve is blocked; or the bottom valve is lurking in the sludge layer in the water, causing the filter mesh to be blocked.(3) The overflow parts are seriously worn.The impeller blades, sheaths and shields are worn after long-term use, which affects the slurry pump function.(4) If the gate valve check valve is faulty or blocked, it will cause the flow rate to be reduced or even the slurry cannot be pumped.(5) Leakage in the outlet pipeline will also affect the water supply
