Which is a good diesel self-priming sewage pump

100 caliber 4-inch diesel self-priming sewage pumpThis series of water pumps is a self-priming single-stage centrifugal water pump, driven by an air-cooled direct injection four stroke diesel engine. The shell is made of die cast aluminum alloy, the pump body adopts mechanical sealing device, and the water seal adopts ceramic material dynamic ring and graphite material static ring. This series of water pumps has a compact structure, light weight, small size, beautiful appearance, easy to use, simple maintenance, and wear resistance. When the water pump is in secondary use, a small amount of water needs to be filled into the pump. After use, the pump can absorb water on its own without the need to install a bottom valve. This series of water pumps is particularly suitable for mobile irrigation and frequent area irrigation. Widely used in agriculture, factories, mines, enterprises, construction sites, communication, underground cables, pipeline maintenance, landscaping, and fisheries, it is an ideal irrigation equipment.

The inspection method is as follows: If the diesel engine water pump produces a thumping sound during operation, and the cycle is proportional to the speed, and it feels laborious to rotate the rotor by hand, it indicates that there is a problem. If there is a slight roughness or tearing phenomenon on the bearing raceway, and intermittent sounds are heard inside the bearing, there may be uncertain dead points when rotating the rotor by hand, usually due to damage to the ball cage or rupture of the inner ring. Don't panic when encountering the above situation, there are different ways to deal with it. Firstly, the bearings of the diesel engine water pump must be replaced to prevent further damage. Furthermore, it is necessary to ensure bearing lubrication by inspecting and replacing the upper and lower end cover bearing chambers on the water pump. There are also skeletons, oil seals, and lithium based grease to ensure that the bearings work in a well lubricated state for a long time.

Because the use of mobile sewage pumps is above the water surface, the medium being transported is a mixture of liquids containing solid materials and large particles; The diesel engine water pump is located very close to other equipment; Due to the vertical arrangement of the water pump, the weight of the rotating components is in the same direction as the water pressure borne by the impeller. These issues make the requirements for sealing, engine load capacity, and selection of sewage pumps higher than those of general sewage pumps. In order to extend the service life of diesel engine water pumps, most manufacturers at home and abroad have put effort into the protection system of water pumps, which can automatically alarm and provide early warning mechanisms in case of pump leakage, overload, overheating and other faults. It is necessary to install a protection system in the water pump for automatic shutdown and maintenance.
