The QY series oil-immersed submersible electric pump is a mobile submersible drainage and irrigation equipment that combines a pump and a machine. Its characteristic is that the motor is equipped with transformer oil, which improves the working conditions of the mechanical seal, and the external water does not enter the motor. The liquid quickly conducts the heat inside the motor, and the cooling effect is very good, so that the temperature rise of the motor is greatly reduced, thereby increasing the overload capacity of the submersible electric pump. In addition, the bearings of the oil-immersed submersible electric pump are also immersed in the oil to work , Lubrication and cooling are well guaranteed, so the service life of the bearing is longer than other types of submersible electric pumps.
The QY series submersible electric pump has the advantages of high lift, small size, light weight, convenient movement, and durability. At the same time, the company has installed a special overcurrent protection device inside the electric pump, and has obtained a national utility patent, number: ZL022 15724.7 The oil-immersed submersible electric pump overcurrent protection device can protect itself in the state of serious undervoltage, overload and lack of phase of the electric pump power supply, not the motor winding burnt out. It does not require the user to configure a protection switch, which saves the user's expenses, and It can prevent the quality of the switch from affecting the user's use.
QY series electric pumps are suitable for underground water pumping in low water level areas, groundwater extraction in field operations, agricultural well irrigation, water tower water delivery, fountains, flood control drainage, municipal construction drainage, and other water supply and drainage.
