Rotor pump is a medium pressure single action fixed-blade pump. The pipe threads on both sides of the rotor pump body are connected with the oil pipe, which are the oil inlet and the oil outlet. Eccentricity between the pump body and the rotor to form a crescent-shaped cavity. When the motor rotates through the belt pulley, the vane in the rotor slot closely presses on the pump body wall of the rotor pump due to the centrifugal force. When the blade begins to turn from the tip of the crescent-shaped cavity to the middle, the space between two adjacent blades and the pump body gradually becomes larger to complete the oil absorption process. After passing the midpoint, the space for the rotor pump is gradually reduced from large to complete and the pressure oil is pressed out of the outlet at the other crescent. The right end of the rotor pump cover with packing, packing gland and gland nuts pressed to prevent the oil along the shaft seepage, sealing effect. The rotor pump body is equipped with bushing, the bushing is easy to replace after being worn. High-viscosity rotor pump often fat, electric drum pumps for high-speed operation, easy to volatile grease, it must be maintained at the bearing lubrication, and pay attention to Tim. High-viscosity rotor pump often check and repair, electric drum pump should always be checked and repaired, to check the power cord: the internal wiring, plugs, switches are good, the insulation resistance is normal, brush tailstock is loose, commutator and brush contact Good, armature-level expansion stator winding there is a moderate phenomenon, the bearing and rotating parts are damaged and so on. High Viscosity Rotor Pump Observe the insulation resistance, long-term use of electric pump or unused or in wet environments, must be measured before using 500 winding insulation resistance. If the insulation resistance between winding and motor shell is less than 7, the winding must be dried. Although the viscosity of the viscous rotor pump coating process is relatively simple, but the actual construction requirements are quite strict, just choose a good adhesive, may not be able to get high viscosity strength. It is necessary to select the right adhesive, but also strictly in accordance with the correct process of adhesive coating the right adhesive, but also strictly in accordance with the correct process method line viscosity coating in order to obtain a satisfactory coating effect. In recent years, surface coating technology in China's equipment maintenance has been widely used for a variety of materials, parts and equipment repair. Its working principle is to add molybdenum disulfide, metal powder, ceramic powder and fiber and other special filler adhesive, directly applied to the surface of materials or parts, so that it has a wear-resistant, corrosion and other functions, mainly for surface strengthening and repair . Its process is simple, convenient and flexible, safe and reliable, does not require specialized equipment, just a good glue coated on the surface of the cleaned parts to be cured after curing can often operate at room temperature, will not make the parts Produce thermal equivalent effect and deformation. High viscosity rotor pump in daily use, pay attention to save The electric pump should be placed in dry, clean and non-corrosive gas environment. Save each part and exchange the same parts, the demolition of high-viscosity rotor pump, you should save each part, pay special attention to flameproof parts explosion-proof surface can not damage the hairline, including insulation pads and casing, if any Damaged, you must replace the same new parts, shall not use less than the performance of alternative raw materials or parts of the original specifications do not match, all parts should be assembled according to the original location, can not be omitted. High viscosity rotor pump in daily use focus on routine maintenance work in accordance with certain problems and principles of good control, to fully demonstrate the control and production, get a good way to maintain and extend the service life.
