Magnetic Drive Centrifugal Pumps

Magnetic drive centrifugal pumps is made up of three: pumps, magnetic coupling, motor parts.Key components magnetic coupler by the outer magnetic rotor and inner rotor and not of permeability of sleeve.When the motor drives the outer magnetic rotor rotating magnetic field can penetrate air gap and the magnetic material, magnetic drive is connected with the impeller in the rotor synchronous rotation, realize the power out of contact, the dynamic seal into static seal.Due to centrifugal pump shaft, the inner magnetic rotor pump body, isolation sets of completely closed, so as to thoroughly solve the problem of “run, run, drip, leak”, eliminates the oil refining chemical industry flammable, explosive, toxic and harmful medium through the pump seal leakage of potential safety problems, effectively guarantee the staff’s physical and mental health and safety in production. Magnetic drive centrifugal pumps maintenance 1. The ban on idling running Because once the lack of liquid running magnetic drive pump, the pump cavity of the sliding bearing will lose lubrication under the condition of high speed rapid wear.Cutting the heat generated by the magnetic field in magnetic rotor magnetic eddy current is enough to make the magnet demagnetization.Although some magnetic drive pump factory boasts its magnetic pump ability idling, actually has a premise, that is resistant to idle time, can only be empty for 3 to 5 minutes. 2. The ban on long closing valve operation When the flow is close to zero value, power is not needed for the impeller is 0, the impeller on the resulting power will be converted to heat, so as to vaporize.Follow the bearing temperature wear and high temperature demagnetization rotor and isolation sets of friction. 3. Avoid cavitation Casual line, transmission medium level changing, medium temperature will change the pump NPSH effectively, easy to produce cavitation.In a very short period of time, can cause magnetic pump cavitation scrap. 4. The ban on extreme flow conditions for a long time running Magnetic drive pump within the principle of flow operation, and can lead to high bearing load. 5. It is strictly prohibited to more than the rated temperature difference Magnetic drive pump in use process to regularly monitor the temperature change, must not exceed the rated temperature. 6. To avoid thermal shock General centrifugal pump heating or cooling rate is not greater than 10 degrees c/min. 7 after priming start magnetic pump Magnetic drive pump before the operation, need toRead More…

Hot Oil Pump

Overview: Hot oil pump is a single-stage centrifugal pump, applicable temperature: less than 370 degrees Celsius. Flow 1-500 cubic meters per hour.Manufacturer and suppliers is china Botou Haina Pump Industry CO.,Ltd. Structure: Support of hot oil pump adopts the structure of the double end ball bearing supporting, front-end used lubricating oil, the back end lubricated by grease, with an oil conduit in the middle, to observe the conditions of sealing and recovery of heat conduction oil. Assemble: 1. Install bearing respectively on the bearing box and housings. 2. The circle will be felt in a bearing end cover a, c, and bearing box. 3. The bearing end cover b, c on the bearing seat and bolts. 4. Will pack good bearing wear on the shaft bearing box, round nut on the screw, and the bearing end cover a fastening on the bearing box. 5. The axial load bearing, bolted, screw the adjusting screw, and the bearing installed on the bearing seat, will block water trap at lower bearing appropriate location. 6. The connecting tube fixed on the bearing seat, and pump cover on the connecting tube bottoms, mount and tighten the impeller, at the bottom of the shaft in turn mount pump devices for cover, and bolted, the adjustment screw impeller with bearing box with clearance between the front cover, (control within 1 ~ 1.5 mm) set with nut, bolt fastening. 7. Bolt, motor bearing is installed on the bearing seat at the top of the shaft coupling components, and the motor shaft coupling with fastening screw fastening on the motor shaft, the motor installed on the motor bearing, and bolt, nut fastening. 8. From the pump export order to asbestos mat, bend, the liquid components of produced liquid, and fixed bearing seat. Hot oil pump operation specification This standard specifies the operation staff must abide by the safety rules of heat conduction oil pump (2) of this standard is only Yu Zhongrong environmental equipment workshop heat conduction oil pump station 2, before the start of preparation 1) check the oil pump machine lubricating oil is in the calibration of the center line, avoid too high or too low; 2) check the pump parts with or without fixed connection screw loose coupling two shaft position is concentric, end clearance fits (3-5 mm); 3) turning 3-5 circle whether rotating flexible, the presence of resistance and noise; 4) the transmission of heatRead More…
