LCW-type high viscosity pump Roots sub-belt drive and gear reducer drive in two forms. This Roots pump: low speed, high efficiency, small size, large flow, low power consumption, self-absorption ability, without oil, easy to use and so on. Can be widely used in transportation of petroleum and petroleum products (gasoline pump for copper leaf) and the factory to convey a variety of oils and liquids. Such as crude oil, paint, lubricants, glass plastic, oleic acid, toothpaste and light alkaline (soap processing) liquid; food processing can transport a variety of liquids such as soy milk, yeast, syrup and so on. 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 period according to the actual conditions of use and can meet the performance requirements and other considerations, by the user discretion. General new Roots pump, pumping clean and dry gas, it is recommended to change the oil around 100 hours time. Oil to be seen after the black metal powder, the oil may be extended after the expiration date. 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 the aging degree of sealing glue seal, check whether the exhaust valve cracking, cleaning the valve plate and the exhaust valve seat on the dirt. Clean the entire Roots pump chamber components, such as the rotor, rotary blade, spring and so on. General use of gasoline cleaning, and drying. After cleaning the rubber parts with a dry cloth can be dry, clean the assembly should be carefully placed bruised and bruised. 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 joints with loose phenomenon. Rotate the Roots pump by hand and see if the 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 of the range indicated on the sign to ensure the Roots pump at maximum efficiency point of operation, in order to get the maximum energy-saving effect. 10, Roots pump to stop using, first close the gate valve, pressure gauge, and 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).
