What is the main reason why horizontal double suction centrifugal pumps can not pump water?

　　Horizontal centrifugal pumps do not pump water because of mechanical failure, wear and tear of the drive belt, excessive resistance loss, other factors, etc. There may be a number of reasons, the following Schaumburg pump valves will talk about the reasons and solutions for horizontal pumps do not pump water.

　　Horizontal double suction centrifugal pump does not water some of the reasons

　　Pump power problem: If the pump does not have enough power supply, it may not work properly.

　　Pump suction port clogging: if the pump suction port is clogged, water will not be able to enter the pump inside, which will lead to the pump not discharging water.

　　Pump outlet blockage: If the pump outlet is blocked, water will not be able to flow out of the pump, resulting in the pump not dispensing water.

　　Pump bearing failure: If the pump bearing fails, the pump will not work properly, resulting in the pump does not produce water.

　　Pump motor failure: If the pump motor fails, the pump will not work properly, thus resulting in the pump not water.

　　Pipe blockage: If the pipe is blocked, the water will not be able to flow into or out of the pump, which will result in the pump not discharging water Pipe blockage: If the pipe is blocked, the water will not be able to flow into or out of the pump, which will result in the pump not discharging water. Clogged pipe: If the pipe is clogged, water will not be able to flow into or out of the pump, resulting in the pump not discharging. Clogged pipe: If the pipe is clogged, water will not flow into or out of the pump, resulting in no water coming out of the pump. Clogged pipe: If the pipe is clogged, water will not flow into or out of the pump, resulting in no water coming out of the pump. Clogged pipe: If the pipe is clogged, water will not flow into or out of the pump, resulting in no water coming out of the pump. Clogged pipe: If the pipe is clogged, water will not flow into or out of the pump, resulting in no water coming out of the pump. Clogged pipes: If the pipes are clogged, water will not flow into or out of the pump, resulting in the pump not discharging water.

　　Pump internal damage: If the pump internal failure, such as impeller or pump casing damage, the pump will not work properly, resulting in the pump does not discharge water.

　　Controller failure: If the controller fails, the pump will not work properly, resulting in the pump not discharging water.

　　Low water level: If the water level is too low, the pump may not be able to draw in water properly, resulting in the pump not dispensing water.

　　Circuit failure: If the circuit fails, the pump will not work properly, resulting in the pump not discharging water.

　　Pipe blockage: If the pipe is blocked, the water will not be able to flow into or out of the pump, resulting in the pump not discharging water.

　　Horizontal double suction centrifugal pump does not water solution

　　Horizontal pump does not pump water because there is air in the pump or air in the intake pipe, or the bottom valve is not closed tightly irrigation diversion water is not full, packing leakage is serious, the gate valve is not closed tightly.

　　Solution: first the water pressure up and then fill the pump body with water, and then boot. Check whether the check valve is tight, piping and joints have no air leakage, if found to be leaking, after removing the joints in the lubricant or paint blending, and tighten the screws. Check the oil seal ring of the horizontal pump shaft, if it is seriously worn, it should be replaced with new parts. Pipe leakage or air leakage, may be installed when the nut is not tightened. If the leak is not serious, apply cement to the air or water leak. For temporary repairs, apply soft soap. If the joints leak, you can use tools to tighten the nut, if the leak is serious need to be reassembled and replaced with a new pipe. Reduce the head, press the pipe mouth of the horizontal pump into the water 0.5m.

　　It may be that the impeller rotor is unbalanced or the coupling is poorly combined, the bearing is worn and bent, it is likely that the rotating part of the parts are loose or ruptured, and it is possible that the pipe support is not solid, etc.. It can be easily solved by using the methods of adjustment, repair, reinforcement and replacement.

　　It is likely that the installation of the nut is not tightened. If the leakage is not serious you can apply cement or cement paste to the leaking area. Temporary repairs can be made by applying soft soap or wet clay. If the leak is at a joint, tighten the nut by hand. If the leak is serious, it will need to be reassembled.

　　Horizontal pump pumping water may be too tight packing pressure, cooling water can not enter the packing or shaft surface damage. You can take appropriate measures such as relaxing the packing and clearing the blockage of the sealing tube. Packing wear need to be replaced with new ones. Before installation, the packing can be soaked in engine oil first and then installed one by one, the cuts need to be staggered so as to minimize water leakage. After the packing installation is completed, you need to tighten the gland, and then adjust the tightness when running.
