I. Adjustment of Pressure Regulator of Air Compressor
The unloading pressure is adjusted by the above adjusting bolt, which rotates the bolt clockwise, increases the unloading pressure and decreases the unloading pressure counterclockwise.
The differential pressure value is adjusted by the differential knob at its bottom, which rotates counter-clockwise, reduces the differential pressure value of the air compressor, rotates clockwise and increases the differential pressure value. The minimum pressure difference is recommended to be 0.06 MPa and the adjustment range is 0.06-0.25 MPa.
II. Air filter
Dust inhaled from the air is blocked in the filter to avoid premature wear and tear of the screw air compressor and blockage of the oil separator. Usually after 1000 hours or a year of operation, the filter element should be replaced, and the replacement time interval should be shortened in dusty areas. In order to reduce the parking time, it is suggested that a new or cleaned spare filter element be replaced.
1. Clean filter element steps
A, tapping the two ends of the filter core to remove most of the heavy dry sand, B, dry air with less than 0.28MPa, blowing in the opposite direction of the inhaled air, the nozzle is 25 mm apart from the folded paper, and blow up and down along its length; C, if there is grease on the filter element, it should be washed in warm water without foam detergent, and at least 15 minutes in the warm water. Wash with clean water in hose. Do not use heating method to accelerate drying, a filter can be washed five times, then discarded and not reused; d, put a lamp in the filter to check, if found thinning, pinholes or damaged places should be discarded.
The inner and outer surfaces of the cooler tubes should be kept clean, otherwise the cooling effect will be reduced. Therefore, regular cleaning should be carried out according to working conditions.
IV. Gas Storage Tank/Oil/Gas Separator
Standard manufacture and acceptance of pressure vessels for gas storage tanks/oil/gas separators shall not be modified arbitrarily.
