Ingersoll Rand Replacement 37951761 Air Compressor Valves
Product Description:
The minimum pressure valve is composed of valve body, valve core,
spring, sealing ring, adjusting screw, etc. It is installed at the
outlet of the oil separator. Its function is to keep the pressure
in the oil separation tank from falling below 0.4MPa. The
compressed air containing oil can be separated better in the
separator and the loss of lubricating oil can be reduced. At the
same time, it can ensure the gas pressure required to establish the
oil pressure. The minimum pressure valve also functions as a
one-way valve to prevent the compressed air in the system from
flowing back when the system is shut down. The holding pressure of
the minimum pressure valve has been adjusted before leaving the
factory. If the holding pressure changes due to a long time of use,
it can be adjusted by the adjustment screw on the valve.
Minimum pressure valve action:
- Priority is given to establishing the circulating pressure required
by the lubricating oil at startup to ensure the lubrication of the
machine.
- The oil and gas barrels can be opened only after the gas pressure
exceeds 0.45MPa, which can reduce the air flow rate through the oil
and gas separator. In addition to ensuring the effect of the oil
and gas separator, it can also protect the oil and gas separator
from damage due to excessive pressure difference.
- Non-return function: When the pressure in the oil and gas barrel
drops after shutdown, it prevents the pipeline compressed air from
returning.
There is a valve on the end cover of the oil separation tank. When
the air pressure in the oil separation tank reaches 1.1 times the
set value, this valve will automatically open to release some air
and reduce the air pressure in the oil separation tank. When the
screw air compressor is working at full load, gently pull the vent
lever on the valve. If the valve can vent outward, it means normal.
There is a pressure gauge on the oil separation tank, which mainly
detects the pre-filter pressure. The bottom of the oil separation
tank is equipped with a drain valve, and the drain valve should be
opened regularly to let off the water and dirt deposited on the
bottom of the oil separation tank.
There is a transparent oil level mirror next to the oil separation
tank to show the level of the oil separation tank. The correct oil
level is when the screw air compressor is working normally, the oil
level is in the middle of the upper and lower degrees. If it is too
high, it will run away, and if it is too low, it will affect the
performance of the whole machin
