Poor sealing may cause the slurry pump to be directly scrapped

In some special dredging industries, we often see a mortar pump, or we call it a slurry pump. The technology of the slurry pump is very simple. It relies on vacuum centrifugal force to brake the water. This process must be To maintain its tightness, the mechanical seal of the slurry pump is the focus of the entire component work. At the same time, only the sealing can improve the efficiency of the slurry pump as much as possible. The slurry pump is generally driven by a belt, which can be used in the range of 80° to -20°. Various tests also challenge the mechanical seal of the slurry pump. Because of the effect of thermal expansion and contraction, the slurry pump sometimes The deformation leads to the failure of the sealing rubber ring, which brings great difficulty and technology to the use and manufacture. Don't look at the mechanical seal for slurry pump is just a simple and small device, but if it is used improperly, it may also cause problems. Resulting in the complete scrapping of the slurry pump. Due to the huge centrifugal force and the huge pumping force, the slurry pump has been subjected to great force. If the seal is not good, it may cause the slurry pump to fall apart, and the impeller inside will be damaged. If there is air leakage or water leakage However, it will also lead to insufficient suction, lower efficiency, and more energy use. Generally, the flow range of the slurry pump will be 30-2 km/h, and the maximum lift can reach 130 meters, and the smaller lift is 15 meters. Meters, the mechanical seals used for slurry pumps are also different according to their flow rates. In some water plants, power plants or sewage enterprises, the slurry pump is widely used, and whether it can work normally is also related to whether the entire work can be successfully completed. Therefore, each enterprise must check whether the seal of the slurry pump is in good condition before starting work. , Mechanical seals for slurry pumps can be bought in many gold accessories stores, but due to different specifications and materials, different manufacturers, and different models of slurry pumps used, the prices are often very different. In the process, the waste water that needs to be discharged is pumped to a higher head by vacuum centrifugation. If the slurry pump is well sealed, it may bring about a better improvement in efficiency. Generally speaking, slurry pumps used in mines often require a larger head, which also brings higher requirements to the seal. If the seal is not in place, or is not reliable, and is not tightened tightly enough, it may lead to insufficient suction. As a result, the impeller wears too much. 80% of the concentrators have to use the slurry pump. They have very high requirements for sealing. Due to the harsh production environment, the sealing ring of the slurry pump needs to have a longer life. No need to replace frequently. When many companies check the air tightness, they will soak the slurry pump into the water with a mechanical seal to see if there is water on the water surface. If the air tightness and water tightness are truly achieved, it can be used. In all the enterprises dealing with Hefei water, almost all of them have the equipment of slurry pump, especially in some power facilities, coal washing plants, steel plants and ore dressing plants. The mechanical seal of the slurry pump, this kind of rubber seal ring can resist a certain stretch and also has a certain buffering effect.
