The air compressor has an excessive oil discharge capacity, is water cooled, the cooler does not lea

6kg of exhaust pressure??

What is the rated working pressure on the nameplate of the machine? 7 or 8kg?

If it's 6 kg exhaust pressure, what is your differential pressure setting? Or 1kg?

If the differential pressure is set, the lower exhaust pressure is the same, and it is strange that the oil does not run!!

If the differential pressure is set to 1 kg, the machine is prone to frequent start-up, and the intake valve diaphragm is prone to wear.

In this way, turn your exhaust pressure back to 7 or 8kg, set the differential pressure to such a thing, and install a pressure reducing valve at the exhaust port.

I guess you're blowing bottles. Now there are twin-screw air compressors on the market specifically for the blowing industry, 90kw 20 cubic min, 5kg machines. Don't buy this standard twin-screw air compressor in the future, even if you install a pressure reducing valve, it's still a waste.

The 6kg pressure is a little lower, but it will not run out of oil, maybe the oil separation effect used by the maintenance company for you is not good, or the oil return pipe is not in place, or the oil return check valve is a problem.

The following points: 1) The oil level is too high, and the injected oil is excessive. Drain the oil to the normal position after removing the pressure;

2) The return pipe is blocked. Can be inspected for replacement;

3) The installation of the oil return pipe (the distance between the oil separation core bottom part is 1-2mm) does not meet the requirements and can be readjusted;

4) When the unit is running, it is overloaded and used at low pressure, and the gas consumption increases, which will not be caused by the high pressure of the gas storage tank;

5) The inside of the barrel body of the oil separator is damaged, and the dismantling inspection can only be found;

6) Oil deterioration or overdue use;

7) The loss of control of the return check valve will cause the oil to flow back to the oil separator after the unit is shut down, and the oil will run out if it is started again;

8) Damage and rupture of the core of the oil separator of the air compressor.

9) There is a leakage point at the minimum pressure valve or the minimum pressure valve is opened in advance, resulting in low pressure inside the oil, high gas mist concentration, fast flow rate through the oil content, increased oil load, reduced separation effect, and increased oil consumption.

Is it a built-in oil? It is very likely that it was not installed properly when it was installed.

If there is oil in the cooler cooling water drain pipe, it may be due to the following reasons:

1.Cooling System Leakage: If there is a leak in the cooling system, lubricating oil in the engine can enter the cooling system and flow out through the drain pipe. In this case, the leak needs to be inspected and repaired.

2.Excessive lubricating oil: If the amount of lubricating oil in the engine is too large and beyond the normal range, some of the lubricating oil may be pushed into the cooling system by pressure and flow out of the drain. In this case, it is necessary to change or adjust the amount of lubricating oil used in time.

3.Poor exhaust: If the exhaust port is blocked or the valve is not closed tightly, etc., the exhaust will be poorly discharged, and a high pressure will be generated when the engine is activated, in which case some lubricant may be pushed into the drain pipe and flow out.

Whatever the cause of the problem, it should be dealt with as soon as possible. It is recommended that you find a professional technician for inspection and repair.

There are several possibilities for cooler condensate with oil:

1.The return line is clogged. Solution: Remove and clean up.

2.The oil is broken or the oil quality is not good. Solution: Replace the oil.

3.The minimum pressure valve opening pressure is too low (opening pressure 4 kg). Solution: Adjust the opening pressure, or replace the minimum pressure valve, or replace the minimum pressure valve repair kit.

4.The air consumption is too large, and the air compressor runs at low pressure for a long time, less than 6 kg. Solution: Add an air compressor.
