Maintain the flexibility of the lobe pump can make the use of better results

Shanghai enterprise - Qinping Machinery has conducted long-term research on lobe pump, and the product adopts modular design and overall casting processing. Assuming that it has not been maintained for a long time, the lobe pump later when it is used again, the use may not be as good as our previous use. (1) Check the lobe pump and pipeline and the combination of the phenomenon of loose. Rotate the lobe pump by hand and try to see if the lobe pump is flexible. (2)Add bearing lubrication oil to the bearing body, observe the oil level should be at the center line of the oil mark, and the lubricant should be replaced or replenished in time. (3) unscrew the pump body of the lobe pump draw plug, fill the draw water (or draw slurry). (4)Close the gate valve of the outlet pipe and export pressure gauge and import vacuum gauge. (5)Start the motor and try to see if the motor steering is correct. (6)Start the motor, when the lobe pump is running normally, open the outlet pressure gauge and the inlet vacuum pump, and gradually open the gate valve after it shows the proper pressure, and check the motor load at the same time. (7) Try to control the flow and head of the lobe pump within the range indicated on the label to ensure that the lobe pump operates at a high efficiency point in order to obtain a large energy-saving effect. (8)During the operation of the lobe pump, the bearing temperature should not exceed the ambient temperature of 35C and the high temperature should not exceed 80C.(9)If abnormal sound is found in the lobe pump, it should be stopped immediately to check the cause. (10) When the lobe pump is to be stopped, close the gate valve and pressure gauge first, then stop the motor. (11) lobe pump in the work of 1 month, after 100 hours to replace the lubricant, after each 500 hours, change the oil once. (12)Adjust the packing gland frequently to ensure that the drip inside the packing chamber is normal (in order to become a drip leak out). (13) Regularly check the wear of the shaft sleeve, and replace it in time after the wear is large. (14) lobe pump in the winter season, after parking, the pump body needs to be unscrewed lower water release screw to release the media net. To prevent freezing and cracking.
