the power used is not matched

　　Second, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever, 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 mayKootra,　　The treatment methods are as follows: Check whether the current and voltage of the water pump are abnormal at this time. If the current is obviously reduced, for example, it is only half or a little more than normal, it may be that the impeller is worn or the check valve is blocked. If the current is not much different from the normal current, it can be　　Many users, including new practitioners of slurry pumps, often fail to distinguish the difference between submerged vertical slurry pumps and submerged slurry pumps. The names of submerged and submerged slurry pumps seem similar,KootraWQ submersible sewage pump, but there are essential differences. What is the difference between submersible slurry pump and vertical slurry pump?Fusagasuga,　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　The utility and durability of the utility model so the polymer composite materials are generally used in production.　　The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water, otherwise the mechanical seal will be burned.

　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.　　 Lifting, loading and unloading of electric pump: remove the cable and disconnect the power supply.　　 The fixing method of the impeller is changed from screw thread to key clamp to prevent the impeller from falling off and causing damage!superior quality,　　When in use, it can drive the impeller to rotate so as to drive it to flow.　　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.　　Submersible pump is a common water lifting equipment for deep wells. During operation, the whole machine intrudes into the water to extract water from the underground to the surface. It is commonly used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, landscape fountains, etc. Submersible pump is generally divided into clean water submersible

　　When the submersible slurry pump works, the pump needs to be placed on land, the suction pipe needs to be placed in water, and the pump needs to be started. Due to special structural requirements,KootraVertical slurry pump, when the slurry pump motor is submerged in the water, the slurry pump and submerged slurry circulating pump need to be placed above the water surface, so they need to be fixed, otherwise the motor will fall into the waterHigh value,　　 Then reinstall the equipment on the engine and install the rubber hose.　　During normal operation, the impeller of the slurry pump becomes tighter and tighter as it turns. The more it is used, the easier it will operate. However, if the slurry pump reverses, it will directly cause the impeller of the slurry pump to fall off. The slurry pump must be disassembled and then re inspected,KootraZD slurry pump, installed and tested.　　 drainage and water injection with vacuum equipment: the self exhaust of centrifugal pump is the same as the negative pressure exhaust of vacuum pump, so the water ring vacuum pump is used for exhaust to achieve the of water inlet.Kootra,　　 When adding lubricating oil to the pump at ordinary times, and the excess lubricating oil in the pump must be discharged and replaced regularly.　　The submersible slurry pump is developed to adapt to the increasingly complex working conditions and facilitate the use of users. Its use mode is more flexible. The equipment has advanced structure, wide flow passage, strong sewage discharge capacity, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged
