The rotor pump is a pump for medium pressure single acting dosing blades. The pipe threads on both sides of the rotor pump body are connected to the oil pipe, and are the oil inlet and the oil outlet. A crescent-shaped cavity is formed by the eccentricity between the pump body and the rotor. When the motor rotates the shaft through the tape wheel, the blades in the rotor groove are pressed against 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 the two adjacent blades and the pump body gradually becomes larger, completing the oil absorption process. After crossing the midpoint, the space of the rotor pump is gradually reduced from large to large, and the pressure oil is completed, and the pressure oil is pressed out from the outlet at the other tip of the crescent. The right end of the rotor pump cover is filled with packing, which is pressed by the packing gland and the gland nut to prevent oil from oozing out along the shaft and functioning as a seal. The rotor pump body is provided with a bushing that is easy to replace after being worn.
Although the high-viscosity rotor pump sticking process is relatively simple, the actual construction requirements are quite strict. It is not always possible to obtain a high adhesive strength by selecting a good adhesive. It is necessary to select a suitable adhesive, and to apply a suitable adhesive in strict accordance with the correct process, and to strictly follow the correct process to obtain a satisfactory adhesive coating effect. In recent years, surface adhesive coating technology has been widely used in equipment maintenance in China, and it is suitable for the repair of parts and equipment of various materials. The working principle is to directly apply the adhesive of special filler such as molybdenum disulfide, metal powder, ceramic powder and fiber to the surface of the material or part to make it wear-resistant and corrosion-resistant, mainly used for surface strengthening and repair. . Its process is simple, convenient, flexible, safe and reliable. It does not require special equipment. It only needs to apply the glue to the surface of the cleaned parts. After curing, it can be trimmed. It is often operated at room temperature and will not make parts. Produces thermal power equivalent effects and deformations.
The high-viscosity rotor pump is often fatliquored, the electric drum pump is running at high speed, and the grease is easy to volatilize, so the lubrication at the bearing must be kept clean and pay attention to the replacement. High-viscosity rotor pump is often inspected for maintenance. The electric drum pump should be inspected frequently. Repair, check the power cord: internal wiring, plug, switch is good, insulation resistance is normal, the brush tail seat is loose, and the commutator is in contact with the brush. Good, whether the armature windings the stator windings have proper breakage, whether the bearings and rotating parts are damaged, etc. High-viscosity rotor pumps pay attention to insulation resistance, electric pumping pumps that are not used for a long time or used in humid environments. The insulation resistance of the windings must be measured with a 500 meter before use. If the insulation resistance between the winding and the motor casing is less than 7, the winding must be dried.
High-viscosity rotor pumps should be kept in daily use. The electric pump should be placed in a dry, clean and non-corrosive atmosphere. Save each part and replace the same parts. When disassembling the high-viscosity rotor pump, each part should be preserved. Pay special attention to the explosion-proof surface of the explosion-proof part. It should not damage the wool, including the insulating gasket and casing. For damage, the same new parts must be replaced. Substitute materials that are lower than the performance of the raw materials or parts that do not conform to the original specifications shall not be used. All parts shall be assembled in the original position during assembly and shall not be missed.
High-viscosity rotor pump pays attention to daily maintenance work in normal use. It is well controlled according to certain problems and principles. It can fully display certain control and production, get good maintenance and prolong service life.
