Corrosion-resistant magnetic pump assembly and maintenance

Corrosion-resistant magnetic pump as the name suggests is a corrosion-resistant pump, mainly for the transport of corrosive liquids. Corrosion-resistant magnetic pump is a more common in recent years, a magnetic pump, which uses the world's best corrosion-resistant materials. But the instrument will be faulty, so we usually pay attention to maintenance, the following to share with you about the corrosion-resistant magnetic pump assembly and maintenance. (A) assembly sequence 1, the heating oil in the hot rolling bearings until 80 degrees, remove the shaft installed at the shaft. 2, with the shaft bearing pressure mounted in the suspension. 3. Put the paper pad on the two bearing caps and fasten the bolts to the suspension. Pay attention to adjust the gap between bearing and bearing cap (ie, the amount of shaft running in the suspension) 0.2-0.4 mm. 4, the retaining ring, packing gland, packing ring mounted on the shaft, and then fasten the pump cover and suspension together. 5, Put the "0" type seal in the groove of the bushing hole and put the shaft sleeve on the shaft. 6, set the impeller key, mounted on the impeller, back washer, tighten the impeller nut, and then bend back the exposed part of the washer to prevent leaf nut loosening. 7, the complete rotor parts into the pump body, with screws and nuts firm. 8, with screws and spring washers to the feet fixed on the suspension. 9, set the pump coupling keys, fitted with pump coupling. (B) Disassembly: 1, check the pump and pipe joints with loose phenomenon. Turn the pump by hand to see if the pump is flexible and then try the motor steering. 2, add bearing lubrication oil to the suspension, observe the oil level should be between the two oil marks. 3, unscrew the water diversion plug, irrigation water. 4, close the outlet valve and outlet pressure gauges and imported vacuum gauge. 5, start the motor, when the pump is running, working pressure gauge export and import vacuum gauge, depending on the appropriate pressure display, and gradually open the valve, while checking the motor load conditions. 6, try to control the pump flow and head of pump marked on the range, to ensure long-term operation of the pump near the high efficiency point, in order to obtain the maximum energy-saving effect. 7, the pump operation, the bearing temperature does not exceed the ambient temperature of 35 degrees, the maximum temperature does not exceed 80 degrees. 8, if found abnormal noise pump should stop immediately check the reasons. 9, pump to stop using, first close the gate valve, pressure gauge, and then stop the motor. 10, the pump in the first month of work, after 100 hours to replace the oil. After every 500 hours, oil change time. 11, often adjust the packing gland to ensure normal drip filling room. 12, the pump is used in winter season, after parking, the lower part of the pump body to be unscrew the screw plug unscrew the water to prevent the net. 13, long-term deactivation of the pump, the pump should be all open, dry the water, the rotating parts and joints coated with grease installed, properly preserved. We share with you more corrosion-resistant magnetic pump assembly and maintenance, hoping to help you, the service life of the instrument and maintenance of a great relationship. If you usually pay attention to maintenance, you can also understand the instrument in-depth, to avoid problems when the instrument, I do not know how to start.
