Hot spring submersible pump manufacturer

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, mining vertical pumps, etc.

The suitability of the operating conditions and proper management of submersible electric pumps are directly related to their service life. Daily maintenance (which is a routine work) is the responsibility of the operating duty personnel and maintenance personnel of the management unit. Regular maintenance (which is a periodic work) is the responsibility of the maintenance personnel of the maintenance unit. Daily maintenance is a regular work that should be inspected and maintained every shift unless otherwise specified.

Hot spring submersible pump manufacturerInstallation and reassembly of working components of water pump

Before assembly, straighten the water pump shaft, apply anti rust paint and grease to the mating surfaces of the impeller and housing, apply anti rust paint to non mating surfaces, and apply * to the rubber bearing liner (do not come into contact with oil). First, fix the * stage impeller on the water pump shaft with a conical sleeve. After tightening the * stage impeller, place it together with the water pump shaft into the lower shell, so that the end face of the impeller mouth ring contacts the end face of the lower shell sealing ring. Then, install the middle shell and tighten it with bolts to the lower shell. Using this method, complete the installation of all impellers and impeller shells.

Hot spring pump

When assembling the working part of the hot spring pump, the following points should be noted:

Generally, a conical sleeve can be tightened by continuously impacting it three times with a punching cylinder.

During assembly, it is not allowed for the water pump shaft to move in series. Therefore, the lower end of the water pump shaft should be fixed to the lower shell.

A layer of 0.12mm green shell paper pad should be added to the joint surface between the three shells to ensure sealing performance.

After assembly, the water pump shaft should be twisted to ensure even rotation, and the length of the water pump shaft extending from the shell should be checked to ensure it is consistent with before maintenance.

The workplace must be clean, and there should be no mud or foreign objects mixed into the mating surface and stopper of the parts to be installed, otherwise it will affect the assembly accuracy.

Before tightening each stage of the impeller with a conical sleeve, it is necessary to ensure that the end face of the mouth ring is tightly attached to the sealing ring end face of the shell, and the already installed shell should be symmetrically tightened.

Maintenance work of imported deep well pumps

In order to improve the integrity and maintenance quality of water pumps, this specification is formulated to ensure that imported deep well pumps maintain good working conditions. Daily maintenance (which is a routine work) is the responsibility of the operating duty personnel and maintenance personnel of the management unit. Regular maintenance (which is a periodic work) is the responsibility of the maintenance personnel of the maintenance unit. Daily maintenance is a regular work that should be inspected and maintained every shift unless otherwise specified. In general, the dismantling and maintenance of the lifting pump should be carried out once a year. When the water output decreases or the vibration is large, and there is abnormal noise, it is necessary to disassemble and repair it in a timely manner. 1.4 Maintenance standards: Follow the requirements of the equipment manufacturer, and if there are no requirements, follow this specification standard. During operation, it is necessary to observe whether the instrument readings and the vibration and sound of the pump are normal. If any abnormal situations are found, they should be dealt with in a timely manner; Measure the static and dynamic water levels of the deep well every quarter, and the * stage impeller must be submerged 3-5 meters below the dynamic water level. Disassemble the motor and water pump; Clean the components, remove rust, and inspect the wear of the components. If there are no issues, after applying anti rust paint, the water pump and motor can be reassembled and continue to be used. If the components are damaged or severely worn, they need to be overhauled, repaired, or replaced before assembling the water pump and motor.

Advantages of precision cast stainless steel submersible pumps for wells

Precision cast stainless steel submersible pump, due to its use of precision casting technology, has a smooth appearance, no pores, and high mechanical performance. After stamping, the impeller of the stainless steel submersible pump needs to be laser welded. Due to the relatively limited mechanical properties of welding, the impeller of the pump is prone to detachment and breakage during operation, especially in high flow pumps. Therefore, in comparison, precision cast stainless steel submersible pumps can achieve a larger flow range and operate more stably and reliably.

Motor parameters

Submersible motor cable length: 3m. If the user needs to extend the cable, they can call us in advance. The submersible motor is lubricated with clean water, and the motor chamber must be filled with clean water before use. (Note: It must be filled completely, otherwise it will reduce the service life of the motor) If the water is not added, the motor will quickly burn out.

Motor protection level: IPX8

The electromagnetic wire adopts a high-temperature waterproof line.
