Air Compressor Spare Parts Oil Seal 1616574200 1622000900 for Atlas Copco Air Compressors 1619517700 1622462800 Double Lip Oil Seal
The screw compressor has a set of shaft sealing device, its function is to seal the extended end of the crankshaft to prevent the refrigerant gas inside the crankcase from leaking out or outside gas entering the crankcase. The compressor shaft seal structure is mainly composed of a spring seat, a spring, a movable ring, and a fixed ring. Form sealing ring. This mechanical shaft seal has three seals.
Bushing set on host spindle, the role of protecting the main shaft and shaft sleeve on the outside of the shaft sleeve, shaft seal with sealant hole inside out at the same time, the shaft sleeve with the spindle rotation, shaft seal fixed, screw air compressor running time is long, so shaft seal shaft sleeve are vulnerable parts, often need to be replaced, replace the need to pay attention to form a complete set of spindle rotation of the shaft sealing system.

The role of shaft seal:
Prevent the leakage of high pressure liquid from the pump and prevent air from entering the pump.Although the position of the shaft seal in the pump is not large, but the normal operation of the pump is closely related to the shaft seal.If the shaft seal is selected improperly, not only in the operation of the need for frequent maintenance, leakage of a lot of liquid is conveyed, and may be due to the leakage of flammable, explosive and toxic liquid caused by fire, explosion and poisoning accidents, the consequences are unimaginable.Therefore, the shaft seal structure must be selected reasonably to ensure the safe operation of the pump.
1. Due to the atmospheric pressure with the outside world in cylinder, will inevitably make steam in cylinder or cylinder outside air along the radial clearance between shaft and cylinder leakage or leakage into, thereby causing loss to the working medium, the deteriorating operating environment, and heating shaft neck or make the steam into the bearing chamber, causes the deterioration of oil, leaking into the air and vacuum, thus increasing the extraction load, the unit will reduce the efficiency,To this end, the rotor through the cylinder at both ends are equipped with a seal, the seal is called the shaft end seal for short.High pressure shaft seals are used to prevent the leakage of steam out of the cylinder, and low pressure shaft seals are used to prevent the leakage of air into the cylinder.
2.Steam turbine operation is bound to have a part of the steam leakage from the shaft end to the atmosphere, resulting in the loss of working medium and heat, but also affect the turbine generator working environment, if the improper adjustment of steam leakage is too large, will make the bearing near the shaft seal temperature rise or make the bearing oil water.For this reason, in all kinds of units, set up the shaft seal heater, in order to recover the steam turbine shaft seal leakage.
3.Prevent the steam in the cylinder and the leakage of the valve stem from leaking to the outside, polluting the environment of the steam turbine room and the quality of the bearing lubricating oil. During the normal operation of the unit, the high-temperature steam flows through the large shaft of the steam turbine, making it heated and causing the bearing to overheat. Prevent air from leaking into the vacuum part of the cylinder. Ensure the vacuum effect and degree of vacuum of the condenser when the unit is started. Recover the leakage of steam seal and valve stem to reduce the loss of working medium and energy.
4.In the steam turbine brake shutdown and the condenser needs to maintain a vacuum during the whole hot state shutdown process, to prevent air leakage into the steam turbine, accelerate the steam turbine internal cooling, resulting in bending of the shaft.
Tips:
This is only a part of the part numbers, many oil separator filters P/N are not listed, in addition there are replacements filters for many other air compressor brands.
Company profile:
Filters are part of the air handling system and can provide the clean compressed air needed to remove oil and impurities. It can be used not only in pneumatic systems and pneumatic tools, but also in food, pharmaceutical and other industries.
