SULLAIR air compressor water cooler accessories features
First, oil and gas barrels
Oil and gas barrels have two functions: oil and gas separation and oil storage.
After the compressed oil and gas mixture is discharged to the oil and gas tank, most of the lubricating oil can be separated by rotating in the oil and gas barrels. The lubricating oil stored in the oil and gas barrels is more lubricating oil, and the newly separated hot oil immediately participates in the next cycle, which is beneficial to reducing the row. Gas temperature.
There is an oil level indicator on the side of the oil and gas tank. There is a filling hole on the barrel for refueling. The oil level of the static lubricating oil should be between the upper limit and the lower limit of the oil level meter.
Below the oil and gas tanks are equipped with oil discharge (water) ball valves. The ball valve should be opened slightly before each operation to eliminate condensed water in the oil and gas tanks.
Once oil has flowed out, close it quickly. Due to the large cross-sectional area of ??the oil and gas barrels, the compressed air flow rate can be reduced, which is beneficial to the separation of oil droplets, and plays a role in the initial degreasing.
Second, the air filter
The air filter is a dry paper filter, and the pore size of the filter paper is about 5 μm.
Its main function is to filter out the dust in the air, avoid premature wear of the screw rotor, premature blockage of the oil filter and the oil separator.
Usually every 500 hours of work should be removed to remove the surface of dust. The method of removal is to use low-pressure air to blow dust from the inside out.
Third, the oil separator
The oil-air separator filter element is made of multi-layered and fine special fibers. The mist-like lubricant contained in the compressed air can be completely filtered after passing through the fine separator. The oil particle size can be controlled below 0.1 μm, and the oil content can be Less than 3PPM.
Fourth, the intake valve
The intake valve is a disc-type intake valve, which mainly controls the empty load by opening and closing the disc in the intake valve; there are two control methods.
A switch type, when the pressure reaches the high limit setting value, closes the air inlet, the pressure drops to the low limit setting value, and reopens the air inlet to work at full load.
Another kind of capacity control, the inlet valve disc micro-close with the proportional valve capacity adjustment control, to adapt to the external gas consumption, so that the pressure is stable within a certain range, the pressure does not reach the volume adjustment pressure, the disc of the intake valve When the air compressor is fully operational at this time.
Five. Safety valve
When the gas pressure in the oil and gas tank is 1.1 times higher than the rated discharge pressure, the safety valve will automatically take off and pressure will be relieved, so that the pressure will drop below the rated discharge pressure.
Six. After the cooler
Compressed air from the smallest pressure valve leads to the aftercooler. The aftercooler is made in one piece with the oil cooler, and its structure is the same.
The cooling fan draws in cold air and blows through the rear cooler rocker. The cooled compressed air temperature is generally lower than the ambient temperature +15°C.
Seven, the minimum pressure valve
Located at the outlet of the oil separator above the oil-gas separator, the opening pressure is set to about 0.45 MPa. The minimum pressure valve mainly has the following functions:
1. When the gas pressure in the oil and gas drum exceeds 0.4 MPa, the air flow rate can be reduced to reduce the air flow rate through the oil separator. In addition to ensuring the oil fine separation effect, the oil separator can be protected from too much pressure difference. damage.
2. The circulatory pressure required for lubricating oil is established prior to start-up to ensure the lubrication of the machine.
3. Back to function: When the pressure in the oil and gas tank drops after the operation of the Sullair compressor parts is stopped, the compressed air in the pipeline is prevented from flowing back.
