Chiriat MoskinVortex pump and pipeline pumpSolutions to product problems

　　To repair the equipment. Submersible slurry pump is a machine used to transport liquid. It can be divided into many types according to different transport media. Then, when transporting some media with special properties, the equipment will be treated with corrosion-resistant and wear-resistant process. Only in this way can the equipment be improved　　The submersible slurry pump is a kind of submersible pump which is connected with the motor and works underwater at the same time. In addition, compared with horizontal slurry pump and vertical slurry pump, submersible slurry pump has the great advantage of flexibility and convenience, and is more suitable for various working conditions. The important technical points of submersible slurry pump are its motor andChiriat Moskin　　During the long-term overload operation of submersible sewage pumps, there are many cases of sudden abnormal failures of submersible pumps. Among them, there are some common obstacles, such as the submersible pump cannot be started after it is powered on, or the motor speed cannot be started after the submersible pump is started. A very small wait　　Analysis of installation problems of slurry pump For bearings lubricated with thin oil, oil shall be added according to the oil level line of the oil standard before start-up. Add (HL hydraulic oil in winter and (hl hydraulic oil in summer. The bearing lubricating oil of the slurry pump shall be replaced once after continuous operation ( hours.Livno,　　 If the impeller of the pump is damaged after a long time of use it will also lead to insufficient liquid supply for the pump.　　The vertical sand pump is generally a submersible slurry pump. Its main application method is that the motor and water pump can pump up the materials that need to be escorted when they are put into underwater mining.　　 First of all, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may

　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　The following inspection shall be carried out: whether there are sundries between the impeller and the pump body due to too tight packing.　　Will be scrapped. In addition,　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impeller　　The operating environment is different: the key difference between the submersible slurry pump and the vertical slurry pump lies in diving. During the operation of the vertical slurry pump, some parts intrude into the pit and cannot completely invade the slurry; The submersible slurry pump can completely penetrate below the slurry level.　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly, the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the gate valve or flap valve is not closed tightly.

　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressuretechnological innovation,　　However, there is also a disadvantage of using the auxiliary impeller sealing system, that is, it takes some energy on the auxiliary impeller of the submersible slurry pump, which is generally about %. However as long as the planning is reasonable, metallurgy and coal　　Vertical height from water outlet center of pump base to flow destination (m)　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speedChiriat Moskin,　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal,Chiriat MoskinDrilling fluid slurry pump,Chiriat MoskinVortex pump and pipeline pump, and then gradually open the outlet sluice valve. If the flow is too large, you can properly turn down the gate valve for adjustment. Otherwise,Chiriat MoskinHorizontal slurry pump, if the flow is too small,Open the gate valve.　　 Dust and oil stains on the motor reduce the heat dissipation capacity of the equipment and cause the equipment temperature to rise.　　Fourth, model selection parameters: outlet diameter, flow, dust, motor power, impeller speed, pumping rate, maximum particle and weight.
