The need for two lubricant systems is caused by the fact that the lubrication of the bearings is carried out by machine oil under a pressure of 2.5-3 ati. Lubrication of cylinders and oil seals is carried out by cylinder oil under pressure exceeding the pressure of the gas in the cylinders.
For lubrication of cylinders and oil seals of air compressors, cylinder oils with a high flash temperature are used, in accordance with the passport of the manufacturer. The use of inappropriate lubrication brands is strictly prohibited. The lubrication of the cylinders is carried out from the lubricator, and the circulation or central lubricant from the gear oil pump driven by the electric motor. The launch of the unit and regulation of the supply, lubrication is carried out until the compressor is turned on. The compressor can only be turned on when uninterrupted oil supply and serviceable operation of the unit is checked. The cleanliness and thoroughness of the assembly of the entire system; Lubrication is the key to the normal and uninterrupted operation of the compressor, the preparation of the entire lubricant system for installation must be given serious attention. Before installation, a gear pump is disassembled, all parts are washed in kerosene and wiped dry. When assembling the pump, the presence and cleanliness of the channels and holes for the lubrication and hydraulic spacing of the roller rollers, the size of the end clearance between the gears and the pump cover, which is regulated by the thickness of the oiled thick paper laid between the lid and the pump body, should be within 0.1- 0.2 mm, rotation of the gears by hand should be light, without jamming. The lubrication system is supplied by the compressor manufacturer; At the installation site, a control assembly and fitting of oil pipes according to the compressor frames is carried out. After the control assembly, all the tubes are disassembled and subjected to grass. Preparation is carried out within 24 hours with a 10%solution of salt or sulfuric acid at 20 ° in order to clean the tubes from pollution and rust.
