When ordering submersible pumps in Fengxian District, Shanghai, the first choice is Samsung brand water pumps

The first choice for ordering submersible pumps in Fengxian District, Shanghai is Samsung brand water pumps. Product overview of stainless steel sewage and sewage submersible pumps in Fengxian District, Shanghai:
Type stainless steel sewage and sewage submersible pump (hereinafter referred to as electric pump), which implements B/- standard, electric pump It consists of three parts: a water pump, a seal and an electric motor. The electric motor is located on the upper part of the electric pump. It is a single-phase or three-phase asynchronous motor. The water pump is located on the lower part of the electric pump. It is a flow channel impeller and volute structure. A mechanical seal is used between the water pump and the electric motor. Each fixed The stop seal uses an oil-resistant rubber sealing ring as a static seal, and its structural design is unique, compact, beautiful, and leading.
Purpose of stainless steel sewage submersible pump in Fengxian District, Shanghai:
The rotor shaft of the electric pump is made of high-quality steel material to ensure that the shaft has more reliable mechanical strength and can effectively improve the wear resistance and corrosion resistance of the shaft. It also facilitates impeller maintenance and disassembly. The motor casing is made of high-quality stainless steel, and the motor is self-cooled by water. When the pump is working, the motor part can be completely exposed to the water for long-term operation, thereby overcoming the problem that the motor cannot dehydrate when the domestic sewage pump is working, and improving the service life of the water pump. .
Stainless steel sewage and sewage submersible pumps in Fengxian District, Shanghai are widely used in industry, agriculture, mining, construction, municipal environmental protection and other places. It can pump liquids containing short fibers, paper scraps, sand solid particles or soft solids, such as mud water, gray water, domestic wastewater, river water, manure, etc. It is an ideal water conservancy equipment for agricultural drainage and irrigation, river pond dredging and construction sites. , but it is not suitable for use in occasions with explosion-proof requirements.
Safety precautions for the use of stainless steel submersible pumps
When the stainless steel submersible pump is working, pay attention to the drop in water level. The submersible pump must not work outside the water.
If during use, if you find that the submersible pump stalls, produces less water, makes noise, and the thermal protector frequently jumps, you should stop the pump in time.
Check whether the power supply voltage is too low or out of power, the cable is broken or the phase is missing.
, check whether the impeller is stuck or worn, whether the water outlet chamber is blocked, whether the lift is too high or too low, whether the filter is blocked, etc. If there is a fault, find the corresponding solution.
. If the stator winding is burned out or other faults occur, it must be sent to the maintenance unit for repair. When reassembling, the air pressure of the sealing part must be checked.
If the cable is found to be damaged, replace it immediately before use. For example, if the stainless steel submersible pump is used to drain thicker slurry, it should be placed in clean water and powered on for a few minutes to clean the slurry in the pump. , then wipe it dry and apply anti-rust oil, and store it in a ventilated and dry place.
Submersible electric pumps work underwater. It is compact and lightweight, does not pump water from the well and does not require a long drive shaft. Therefore, submersible electric pumps are very suitable for rural well water irrigation. The most widely used type is the B-type submersible electric pump. This kind of submersible electric pump uses waterproof measures such as mechanical seals or air seals to keep the inside of the motor dry and free from water intrusion. Pay attention to the following points when using:
Check whether the seals on the air vent, water drain, oil drain hole and cable joint of the pump are loose. If they are loose, they must be tightened.
Use a voltmeter to check the insulation resistance. It should be no less than . megohm. If it is lower than this value, open the water and vent holes for drying or sun-drying.
Check the cable. If it is cracked or broken, it should be replaced to avoid leakage.
Before starting, check all circuits and switches to see if the wiring is correct and secure. Then let it idle for 3 to 3 minutes on the ground (the time should not be too long to avoid damaging parts or burning the motor windings), and check whether the motor is rotating in the correct direction. If there are no problems as mentioned above, it can be put into water for use.
When the submersible electric pump is put into the water for use, the cable must not be stressed. It should be tied to the wooden frame at the wellhead with a rope. The maximum depth that the electric pump can be put into the water is 3 meters, and the minimum depth is . meters (from the center of the impeller).
During operation, changes in water level in the well should be frequently observed. The motor must not be exposed to the water or sink into the mud, so as not to affect the heat dissipation of the motor and burn the windings. The electric pump should be raised and lowered at any time as the water level in the well changes. If the water volume decreases or is interrupted, the cause should be immediately identified or shut down for inspection. The cable must not rub against the well wall to prevent well water from seeping into the motor along the cable core after the cable is worn out.
For new or replaced submersible pumps with integral sealing boxes, after using them for hours, you should check whether the sealing is in good condition. In the future, check once a month. Also check whether the sealing of the shielding sleeve between the motor rotor and stator is in good condition.
After one year of use, the pump should be inspected for corrosion, removed and painted.
If the submersible electric pump will not be used for a long time, it should be carefully inspected and stored in a dry and ventilated house.
