Before starting the pump, the suction pipe and pump must be filled with liquid. After turning on the pump, the impeller rotates at high speed, and the liquid inside rotates together with the blades. Under the action of centrifugal force, it flies away from the impeller and is ejected outward. The ejected liquid gradually slows down in the diffusion chamber of the pump casing, increases in pressure, and then flows out from the pump outlet and discharge pipe. At this time, a vacuum low-pressure zone is formed at the center of the blade due to the liquid being thrown towards the surroundings, which has neither air nor liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of atmospheric pressure on the pool surface. The liquid is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe. Deep well pump is a blade type pump used to lift water in deep wells. It is generally based on a multi-stage structure diagram, and the long shaft deep well pump is a commonly used type of well pump, mostly used in machine wells. Deep well pumps generally consist of a vertical electric motor on top, a water supply pipe and a drive pump shaft in the middle, and working parts such as the inlet of the well pump at the bottom. Deep well pumps are generally segmented multi-stage vertical centrifugal pumps. One of the main manufacturers of deep well pumps, the stainless steel multi-stage deep well pumps produced have excellent quality. Proper use and timely troubleshooting based on the structural characteristics of deep well pumps are crucial for ensuring their safe operation and extending their service life.

Shanghai Yinai Pump Valve is one of the main manufacturers of deep well pumps in China, producing high-quality stainless steel multi-stage deep well pumps. Proper use and timely troubleshooting based on the structural characteristics of deep well pumps are crucial for ensuring their safe operation and extending their service life. Select the flow rate of the deep well pump based on the water output of the well. Each well has an economically feasible water output, and the flow rate of the water pump should be equal to or less than the water output when the well water level drops to half the depth of the well water. When the pumping volume exceeds the water output of the well, it will cause the collapse and sedimentation of the well wall, affecting the service life of the well; If the pumping volume is too small, the benefits of the well cannot be fully utilized. So, the method is to conduct a pumping test on the well, and select the pump flow rate based on the maximum water output that the well may provide. The flow rate of the water pump shall be based on the brand model or the number indicated in the manual.

Based on the depth of water level drop in the well and the head loss of the water supply pipeline, the actual required head of the deep well pump is determined, which is the head of the deep well pump. It is equal to the vertical distance from the water level to the water surface of the outlet pool (net head) plus the loss head. The loss head is usually 6-9% of the net head, usually 1-2m. The inlet depth of the first stage impeller below the water pump should be 1-1.5m. The total length of the underground part of the water pump pipe should not exceed the maximum length specified in the water pump manual for entering the well.

Due to the different working media filled inside the submersible pump motor and the resulting structural differences, the motor casing of hot spring submersible pumps can be divided into four structural forms: water filled, oil filled, dry, and shielded. Each type of submersible pump motor has significant differences in both its structure and the materials and processing techniques used for its main components.

We will now introduce the typical structures, main characteristics, and key components and materials of various submersible pump motors: the structure of well filled submersible motors

The submersible motor used in the well is a water filled sealed structure, with the inner cavity filled with clean water or rust proof lubricant (rust proof grade corrosion inhibitor). The joint surfaces of each joint are sealed with O-ring sealant or sealant. The shaft extension end of the submersible motor is equipped with anti sand sealing devices such as rubber skeleton oil seals or single-sided mechanical seals, which can prevent solid impurities and sediment particles in the well fluid outside the submersible motor from entering the interior of the motor.

There are various types of stainless steel hot spring pumps, with sufficient inventory and fast delivery;

The maximum temperature resistance is between 40 ℃ and 120 ℃. For deep wells with high gas content, the use of gas separation devices can prevent gas blockage;

Zui has a high head of 2-1500M, a flow rate of 5-650m3/h, a power of 3-410KW, and a pump outer diameter of 100-800mm.

Suitable materials can be ordered and produced strictly according to water quality.

Hot spring pumping medium is similar to clear water, a high-temperature liquid with a solid content and specific gravity not exceeding 0.02%. The hot spring pump adopts a professional hot water resistant submersible motor and a high-temperature resistant pump body, and can operate safely at a water depth of 120 meters; The overcurrent components of the pump body are precision cast with wax molds to achieve energy-saving and environmentally friendly effects

Compact structure, easy installation, just place the pump at the bottom of the pump pit. The model of submersible pump is very simple, usually only three sets of numbers. For example, 25-8-22 means a diameter of 25 millimeters, a flow rate of 8 cubic meters per hour, a head of 22 meters, a power of 1.1 kilowatts, a speed of 2900 revolutions per minute, and a voltage of 380 volts. The voltage of a typical submersible pump is 380 volts, except for special pumps. In addition, there are models 32-10-15 and 40-15-30 submersible pumps. When selecting, special attention should be paid to the pump model, flow rate, and head. If the selection is improper, it will not meet the working requirements and the unit efficiency will not be fully utilized. It is also necessary to clarify the rotation direction of the submersible pump. Although there are many models of submersible pumps that can produce water in both forward and reverse directions, the water output will be small during reverse rotation, the current will increase, and sometimes even damage the motor winding. When installing a submersible pump, the cable should be overhead and the power line should not be too long. When the unit is launched, do not put any force on the cables to avoid causing the power lines to break. Do not sink the submersible pump into the mud, otherwise it may cause poor heat dissipation and burn out the motor winding. When starting up, it is advisable to avoid starting up with low voltage. Low voltage can cause the speed to decrease. If it does not reach 70% of the rated speed, the starting centrifugal switch will close, causing the starting winding to be energized for a long time and generate heat or even burn out the winding and capacitor. Do not frequently turn on and off the motor, as it will generate backflow when the electric pump stops. If you start it immediately, it will cause the motor load to start, resulting in excessive starting current and burning out the winding. If the voltage is too high, it cannot be turned on, otherwise it will cause the motor to overheat and burn out the motor winding. Do not let the water pump work under overload for a long time, do not pump water with high sediment content, and the dehydration operation time of the electric pump should not be too long to avoid overheating and burning out the motor. During the operation of the unit, the operator must observe at all times whether the working voltage and current are within the values specified on the nameplate. If they do not meet the requirements, the motor should be stopped to identify the cause and eliminate the fault. Usually, it is necessary to check the motor more frequently. If cracks are found on the lower cover, damaged or ineffective rubber sealing rings, etc., they should be replaced or repaired in a timely manner to prevent water from seeping into the machine. During operation, it is necessary to regularly observe the changes in water level in the well. The motor must not be exposed to the water surface or trapped in mud, in order to avoid affecting the heat dissipation of the motor and burning out the winding. The electric pump should be raised and lowered at any time according to the changes in water level in the well. If there is a decrease or interruption in water volume, the cause should be immediately identified or the machine should be stopped for inspection. The cable should not rub against the wellbore to prevent the well water from seeping into the motor along the cable core after the cable is worn out. After one year of use, the corrosion of the pump should be checked and rust should be removed and painted. If the submersible pump is not used, it should be carefully inspected and stored in a dry and ventilated house. Submersible pump is a widely used water treatment tool. Unlike ordinary water pumps, it works underwater, while most water pumps work on the ground. Before starting the pump, the suction pipe and pump must be filled with liquid. After turning on the pump, the impeller rotates at high speed, and the liquid inside rotates together with the blades. Under the action of centrifugal force, it flies away from the impeller and is ejected outward. The ejected liquid gradually slows down in the diffusion chamber of the pump casing, increases in pressure, and then flows out from the pump outlet and discharge pipe. At the center of the blade, a vacuum low-pressure zone is formed due to the liquid being thrown around, which has neither air nor liquid. The liquid in the liquid pool flows into the pump through the suction pipe under the action of atmospheric pressure on the pool surface. The liquid is continuously sucked up from the pool and continuously flows out of the discharge pipe. Submersible pump - Mechanical Overview Operating Surface Submersible pump is a universal machinery. Its working principle is that the electric motor drives the impeller to rotate at high speed through the pump shaft, works on the liquid, converts mechanical energy into liquid energy, and transports the liquid to the destination.

The inherent weakness of submersible pumps is that the solid medium they pump is mostly soft, limiting the sand content in the water to within 3%. When the sand content is high, it is easy to damage the seal. Once the motor enters the water, the bearings and winding insulation are damaged, leading to motor burnout. In addition, submersible sewage pumps only have single-stage pumps with large flow rates and generally low head, which cannot meet the development and use needs of high head and low flow well submersible pumps in some mines. The development and use of submersible pumps are combined with technological progress, and there are many types of pump development. Submersible pumps can be divided into well submersible pumps, working face submersible pumps, submersible sewage pumps, sand discharge submersible pumps, and mining submersible pumps
