Roots pump usage and characteristics
LC Roots pump consists of the pump body, pump cover, shaft, gear, rotor, packing, gland and other components, the Roots pump belt drive and gear reducer drive in two forms, can reverse the role of both ends of the shaft equipped with Skeleton oil seal, the middle with a return device to prevent air intake or oil leakage design. Use the maintenance Roots pump instructions: First, regular inspection of oil quality, oil deterioration should be found in a timely manner to replace the new oil, to ensure Roots pump is running properly. Second, often check the oil level position, do not meet the requirements must be adjusted to meet Roots pump operation, the oil level to the center of the oil standard prevail. Third, the oil change period according to the actual conditions of use and can meet the performance requirements and other considerations, by the user according to the use of the decision.General new Roots pump, conveying clean and dry Of the gas, it is recommended to change the oil in the work of about three days once the oil can not see the black metal powder, the oil may be extended after the deadline. Fourth, check the Roots pump pipe and joints with loose phenomenon. Rotate the Roots pump by hand and see if the Roots pump is rotating flexibly. V. Lubricating oil is injected into the bearing body to observe the oil level should be at the center line of the oil, lubricating oil should be replaced or replaced promptly Six, under normal circumstances, Roots Oil pump should be observed after 80 days of maintenance, check æ¡· plastic seal aging, check the exhaust valve is cracking, cleaning the valve plate and exhaust valve seat debris on the cleaning of the entire Roots pump cavity Parts, such as the rotor, rotary vane, spring, etc .. General use of gasoline cleaning, and drying. After cleaning the rubber parts with a cleaning cloth can be dry cleaning assembly should be carefully placed bruised. Should be commissioned and then run, usually 2 hours to be airlifted and oil change twice, due to cleaning in the Roots pump will leave a certain amount of volatile, to be normal after operation, and then put into normal work. Eight, start the motor, When Roots pump is working properly, open the outlet pressure gauge and import Roots pump, after showing the appropriate pressure, gradually open the gate valve, while checking the motor load situation .Rotz oil pump during operation, the bearing temperature can not exceed the ambient temperature 35 degrees Celsius, the maximum temperature must not exceed 80 degrees Centigrade. As far as possible to control the Roots pump flow and head in the range indicated on the label to ensure Roots pump work at the highest efficiency point, in order to get the maximum energy saving effect. Stop using the first to close the gate valve, pressure gauge, and then stop the motor. Normal operation Nine, Roots pump in the first month of work, after about three days to replace the oil, every 20 days later, a new oil Interval transfer Packing gland, to ensure normal drip filling room indoor (as a drop of leakage is appropriate.) Regular inspection of the sleeve wear, wear larger should be promptly replaced. Roots pump long-term deactivation, the pump required to be disassembled, Dry the dirt, the rotating parts and joints coated with grease installed, properly stored (not used should be maintained and cleaned.) 10, Roots pump in the winter season when the use of parking, the lower part of the pump to drain snail Unscrew the media to drain the media.
