IHW horizontal pipeline chemical pump principle
IHW horizontal pipeline chemical pump is water pump and water filled three-phase asynchronous motor to irrigation and drainage equipment, with small size, light weight, easy installation and maintenance advantages. Not only for farmland irrigation, flower sprinkler, but also for City, left water tower water supply. Safe and reliable operation, energy-saving and efficient, is an ideal water lifting equipment. Second, IHW horizontal pipeline chemical pump conditions of use: 1, the voltage is 380V (± 10% power supply. 2, the water is generally non-corrosive water, PH value of water pH 6.5-8.5, sand content less than 0.024% (weight ratio), the water temperature is not higher than 40 ℃, excluding oil. 3, electric pump installation should be upright, not lying down installation. 4, according to the height of the pumping water and the diameter of the selection of electric pump, so that the pump in a relatively high efficiency range of operation, the general provisions of the flow rate of 0.7-1.2 times the scope of use. 5, electric pump must be completely immersed in the water work, the normal working hours in the water level 0.5-1 meters. Third, IHW horizontal pipeline chemical pump structure principle IHW horizontal pipeline chemical pump consists of two parts: the pump and submersible motor. Single and multistage centrifugal pumps (Francis or Axial) impellers and guide vanes. Impeller with a taper or key and pump shaft coupling. Submersible motor is a structural form, mainly by the chassis, stator, rotor, up and down the bearing seat and other components, the structure of the bearing, the use of rolling bearings, lubricated with water-resistant grease, and a sealed oil seal. The same type of structure of the motor are water-filled submersible motors, stator windings with insulating sheath water-resistant wire, rotor coated with water-proof anti-corrosion coating, motor shaft extension oil seal and sand thruster to prevent the sand into the body . When the submersible pump connected to 380V three-phase AC, the stator windings produce a rotating magnetic field, so that the motor rotor rotation, impeller rotation, so that the impeller on the water for work, the impeller water through the guide vane body and the outlet pipe to the required the height of.
