Wheel bearing is applied to automobile axle to load and provide accurate guide components for the rotation of the wheel hub, both bearing axial load and radial load. It has good performance to installing , omitted clearance, light weight, compact structure, large load capacity, for the sealed bearing prior to loading, ellipsis external wheel grease seal and from maintenance etc. And wheel bearing has been widely used in cars, in trucks also has a tendency to gradually expand the application.

Roots pump 16 kinds of maintenance methods summary
LCX-type high viscosity pump Roots pump sub-belt drive and gear reducer drive in two forms.This pump has: low speed, high efficiency, small size, large flow, low power consumption, self-absorption ability, Easy to use and so on.It can be widely used in conveying petroleum and petroleum products (gasoline exchangeable copper pump leaf) and various kinds of oils and liquids in the factory such as crude oil, paint, lubricating oil, glass glue, oleic acid, toothpaste and alkali (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 tanker and tanker speed, high efficiency, easy to use, 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 so on , At the discretion of the user.General new Roots pump, pumping clean and dry gas, it is recommended to change oil about 100 hours of work.When the oil can not see the black metal powder, oil extended after the period may be appropriate. , Regular inspection of oil quality, oil deterioration should be found Replace the new oil, to ensure Roots pump is working normally 4, under normal circumstances, Roots pump should be carried out after 2000 hours of repair, check the aging degree of rubber seal, check whether the exhaust valve cracking, cleaning sedimentation in the valve and Dirt on the exhaust valve seat Clean the parts of the entire Roots pump cavity, such as rotors, rotary vanes, springs, etc. Generally, wash with gasoline and dry.Wash dry the rubber parts with a dry cloth Clean the assembly should be gently and accidentally bump 5, Add bearing lubricating oil to the bearing body, observe the oil level should be at the center line of the oil, lubricating oil should be replaced or supplemented 6, Check the Roots pump pipeline And with or without loosening phenomenon. Rotating the Roots pump by hand to see whether the Roots pump is flexible. 7, reassembly should be carried out after the trial run, the general shall be empty for 2 hours and change the oil twice, Pump will be left 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 outlet pressure gauge and import Roots pump, depending on their display after the appropriate pressure , Gradually open the gate valve, while checking the motor load situation , Try to control the Roots pump flow and head in 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 in operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature must not exceed 80 C. 12, Roots pump in the first month of work, after 100 hours to replace the lubrication Oil, after each 500 hours, change the oil once. 13, often adjust the packing gland to ensure that the drip filling room is normal (with drops of leakage is appropriate.) 14, regular inspection sleeve wear, wear larger Should be promptly replaced .15, Roots pump long-term deactivation, the pump required to open all, dry the water, the rotating parts and joints coated with grease installed, safekeeping .16, Roots pump in the winter season, After parking, unscrew the drain plug at the lower part of the pump body to release the net.
