LCW-type high viscosity pump Roots pump sub-belt drive and gear reducer drive in two forms. The Roots pumps are: low speed, high efficiency, small size, large flow, low power consumption, self-absorption ability, Oil, easy to use, etc. It can be widely used in conveying petroleum and petroleum products (gasoline exchangeable copper pump leaves) and various kinds of oils and liquids in the factory such as crude oil, paint, lubricating oil, glass glue, fatty acid, toothpaste and Light alkaline (soap processing) liquid, etc .; food processing can transport a variety of liquids, such as soy milk, yeast, syrup, etc. Loading and unloading all kinds of tankers and tanker speed, high efficiency, easy to use, can be positive and negative work. 1, always check the oil level position, 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. 2, the oil change deadline according to the actual conditions of use and can meet the performance requirements and other considerations, the user discretion. General new Roots pump, pumping clean and dry gas, it is recommended to work about 100 hours oil change once. Can not see the black metal powder, the oil may be extended after the period. 3, regular inspection of oil quality, oil deterioration should be found in a timely manner to replace the new oil, to ensure Roots pump is working properly. 4, under normal circumstances, Roots pump work after 2000 hours should be overhaul, check æ¡· plastic seal aging degree, check the exhaust valve is cracking, cleaning the valve plate and the exhaust valve seat on the dirt cleaning. Roots pump cavity components, such as the rotor, rotary blades, springs, etc .. General gasoline wash, and drying. After the rubber parts dry with a dry cloth can be. hurt. 5, add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil standard, the lubricating oil should be replaced or replenished in time. 6, check the Roots pump pipe and loose joints with the phenomenon of hand rotating Roots pump, see Roots pump is flexible. 7, should be reassembled after the trial operation, the general should be empty for 2 hours and oil change twice, due to cleaning in the Roots pump will leave a certain amount of volatile materials, to be functioning properly, then put into normal work. 8, start the motor, when Roots pump normal operation, open the outlet pressure gauge and import Roots pump, depending on the pressure showed its appropriate, and gradually open the gate valve, while checking the motor load conditions. 9, try to control the Roots pump flow and head in the range indicated on the sign to ensure Roots pump running at the highest efficiency point in order to get the maximum energy-saving effect. 10, Roots pump to stop using, first off Gate valve, pressure gauge, then stop the motor. 11, Roots pump during operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C. 12, Roots pump in the first month of work, after 100 hours to replace the oil, after every 500 hours, oil change time. 13, often adjust the packing gland, to ensure that the drip filling room is normal (as drops into leakage is appropriate).
