1, Roots pump in operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C. 2, the oil change period according to the practical conditions of use and ability to meet the performance requirements and other considerations, the user discretion. Ordinary new Roots pump, removal of clean and boring gas, it is proposed to change oil about 100 hours of work once the oil can not see the black metal powder, the oil can be extended after the deadline .3, Roots pump to discontinue use Under normal circumstances, Roots pump should stop working after 2000 hours of inspection, check the aging level of sealing glue seal, check if the exhaust valve can crack, settle the sediment in the valve plate and the pressure gauge, and then stop the motor. Dirt on the exhaust valve seat Clean the parts of the entire Roots pump cavity, such as the rotor, rotary vane, spring, etc .. Ordinary gasoline cleaning and drying.Wash rubber parts dry with a dry cloth Clean the assembly should be handled with care .4, Check the Roots pump pipeline and the separation of the phenomenon of loosening.Rotate the Roots pump by hand to see whether the Roots pump is sensitive.Check the oil quality, Found that the oil decay should be promptly changed new oil, ensure The work of the pump is normal 5, to the bearing body to participate in the smooth bearing oil, see the oil level should be at the center line of the oil, the oil should be promptly replaced or added.Regular inspection sleeve wear, wear larger should be promptly changed. 6, Roots pump in the first month of work, after 100 hours to change the smooth oil, after each 500 hours, change the oil once.Regular packing gland to ensure normal filling room drip condition ) 7, re-assembly should stop trial operation, the general air operation for 2 hours and change the oil twice, due to cleaning in the Roots pump will leave a certain amount of volatile, to be functioning properly, and then put into normal work. 8, start the motor, when the Roots pump normal operation, open the export pressure gauge and import Roots pump, depending on the pressure showed its appropriate, and gradually open the valve, while checking the motor load conditions 9, try to control the Roots pump Of the flow and lift within the range indicated on the label in order to ensure the highest efficiency point of operation in order to achieve the maximum energy-saving effect .10, Roots pump long-term deactivation, the pump required to open all, dry the water, will rotate Parts and separation Tu Grease installed safekeeping always check the oil level position, to be adjusted to make it fit the request does not meet the rules. When to Roots pump operation, the oil level to the oil standard center shall prevail.
