LC Roots pump maintenance: LC Roots pump belt drive and gear reducer drive in two forms, you can reverse the role of both ends of the shaft oil seal with a skeleton, the middle with a return device to prevent air intake or Oil spill. This series of Roots pumps from the pump, pump cover, shaft, gear, rotor, packing, gland and other components. Use maintenance Roots pump points: First, the reassembly should be carried out after the trial run, generally two hours to be empty and oil change twice, due to cleaning the Roots pump will be left in a certain amount of volatile, to be functioning properly , And then put into normal work. Two, Roots pump in the winter season when used, after parking, the need to unscrew the lower part of the drain screw plug the media to the net. To prevent cracking. Third, regular inspection of oil quality, oil deterioration found Should promptly replace the new oil, to ensure that the Roots pump is working properly. Fourth, check the Roots pump pipe and the combination of loosening phenomenon. Rotate the Roots pump by hand to see if Roots pump is flexible. , Do not meet the requirements must be adjusted to meet the requirements to Roots pump operation, the oil level to the oil standard shall prevail. Sixth, under normal circumstances, Roots oil pump work after 2000 hours should be overhauled, check æ¡· plastic seals The degree of aging, check whether the exhaust valve cracking, cleaning the valve plate and the exhaust valve seat cleaning dirt. Wash the entire Roots pump cavity components, such as the rotor, rotary vane, spring, etc. General gasoline cleaning, And drying.Wash rubber parts dry with a dry cloth that is 7, start the motor, when the Roots pump normal operation, open the outlet pressure gauge and import Roots pump, depending on their display of appropriate pressure, and gradually open the gate valve, at the same time Check the motor load situation Roots pump during operation, the bearing temperature can not exceed the ambient temperature of 35 degrees, the maximum temperature of not more than 80. Try to control the Roots pump flow and lift in the range indicated on the sign to ensure that Luo Roots pump to run at the highest efficiency point, in order to get the maximum energy-saving effect Roots pump to stop using, first close the gate valve, pressure gauge, and then stop the motor Eight, Roots pump in the first month of work, after 100 hours Change the lubricating oil, after every 500 hours, change the oil once.Regularly adjust the packing gland to ensure that the drip filling room is normal (as a drop of leakage is appropriate.) Regularly check the sleeve wear, wear large should be promptly Replace the Roots pump long-term deactivation, the pump required to open all, dry the water, the rotating parts and joints coated with grease installed, properly stored .9 bearing bearing lubrication oil to the body, observe the oil level should be Oil standard Centerline, the lubricating oil should be replaced or supplemented. Ten, the oil change deadline according to the actual conditions of use and can meet the performance requirements and other considerations, the discretion of the user.General new Roots pump, pumping clean and dry gas, It is recommended to change the oil about 100 hours at work.When you can not see the black metal powder in the oil, you can extend the oil change period afterwards.
