The standby submersible slurry pump shall roll the shaft / turn every week to make the bearing uniformly accept the static load and external oscillation. The building structure in the water pump room shall be reconstructed. Sound absorbing and isolating plates shall be installed around the wall and on the top of the machine room and fixed with light steel keel; The connecting holes between the machine room and other rooms are tightly blocked, The bus voltage where the motor is located is V. Due to the uneven cable voltage drop and load distribution, it is also possible that the temperature is too high due to the low voltage of the water pump.Taolagai, other requirements (cable, control box,TaolagaiBooster pipeline pump, liquid level control,TaolagaiSewage pump diving, etc.) Ordinary vertical motor can be used without waterproof, while the motor shaft and pump shaft of submersible slurry pump are coaxial, so the motor must be waterproof and sealed, and the motor and pump can be immersed in liquid at the same time; The vertical slurry pump is an early product, and the submersible slurry pump is a newly developed product according to the market demandEl-Mahalla El-Kubra, There will be no insufficient liquid supply or other problems. This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics ; In practical application, the submersible slurry pump is developing rapidly with its unique advantages. The vertical slurry pump needs to be fixed and installed in use, while the submersible slurry pump can be used directly without immersion, which is convenient and flexible.
Submersible slurry pump can be widely used in mining, power, metallurgy, coal environmental protection and other industries to transport abrasive slurry containing solid particles. Such as ore slurry transportation in metallurgical concentrator, hydraulic ash removal in thermal power plant, coal slurry and heavy medium transportation in coal washing plant, river dredging, river dredging, oil depots chemical industry and power departments of enterprises and institutions to transport oil products and flammable and explosive liquids. The operating temperature should also be within ℃. Pressure. Therefore,TaolagaiTwo stage slurry pump, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.production costs, 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. Rate.
The above introduction is about the cause ysis of the overload of the slurry pump. When we find these conditions when using the pump, All kinds of newly designed mechanical seals of submersible slurry pumps contribute greatly to the growth of market share. rotate the impeller to check whether it is flexible and check whether the seals at the pump vent hole, water drain hole, oil drain hole and cable joint are loose. If they are loose, they must be tightened. The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Lets take a look at the correct disassembly of the impellerTaolagai, It may also be because the pumps liquid supply pipe is blocked by other substances during normal use. The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force. Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s. The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.
