In the case of water loss, oil loss, lack of water, lack of oil, etc., the exhaust gas temperature may
be too high. When the exhaust gas temperature reaches the set temperature, the system will
automatically stop.
The tripping temperature is generally set at 105-110°C
, and the exhaust
temperature can be read on the LCD panel.
4) Oil and gas drums
Oil level indicator is installed on the side of oil and gas barrel. The oil level of static lubricating
oil should be between the high oil level line of the oil level meter and the low oil level line. There
is a drain valve under the barrel. Before starting, the valve should be twisted slightly to remove the
condensate water in the barrel.
Note: once there is oil flow out, close the drain valve
immediately to avoid excessive lubricating oil outflow.
The barrel has a refueling hole, which
can be used for refueling.
5) Oil separator
See the instructions in the following section for more details.
6) Safety valves
When the system pressure is set improperly or out of order, the pressure inside the oil and gas
barrel is higher than 0.1Mpa than the set exhaust pressure, the safety valve will jump away, so that
the pressure will drop below the set exhaust pressure.
The safety valve has been adjusted before
leaving the factory. Please do not adjust it at will.
7) Discharge valve
The relief valve is a mechanical emptying valve installed on the inlet valve. When stopping or
empty the valve opens to discharge the pressure in the barrel to ensure that the compressor can start
or operate under no load.
8) Pressure maintenance valves (also known as minimum pressure valves and pressure retaining
valves)
Located at the outlet of the oil separator above the oil and gas barrel, the opening pressure is set
at about 0.45Mpa, the function of the pressure maintenance valve is: a) When starting, priority is
given to establishing the circulating pressure required for the lubricating oil to ensure the
lubrication of the body.
b) When the pressure exceeds 0.45 Mpa, it can reduce the air flow rate of the oil separator,
