What is the cause of the excessive partial pressure difference of air compressor oil?

There are generally two reasons for this: first.

1. Oil filter plugging; Clause.

Second, there is a problem with the pressure detector.

It may be that the oil is broken and the oil needs to be replaced. Remember to use a wrench when replacing the main unit.

Turn it around, and then pour the new oil into it.

2.It is possible that the oil filter is blocked, and then the oil filter is bypassed.

It has been opened, and the oil will go directly to the host without filtering, and the oil should be changed as soon as possible, otherwise it will be easy to be damaged.

3.There may be a problem with the sensor.

Detection method: remove the oil filter to see, if it is too dirty, it is a problem with the oil filter, and then replace it with a new one, if the new one is blocked not long after, it means that the oil is broken, go to test the oil. Change the oil depending on the situation.

Remove the oil filter, if it is not dirty, it should be the pressure sensor. It's broken.

The partial pressure difference of the air compressor oil is normal, if the pressure difference between the pressure before separation and the pressure difference after separation is exceeded, the controller will have a large pressure difference alarm.

1；Check whether the pressure sensor is normal before separation to avoid mismeasuring the pressure.

2；Check whether the oil separator core is blocked;

3；Check that the minimum pressure valve is not damaged (the normal opening pressure is.

4；Check that the exhaust pressure sensor is able to measure the pressure properly.

5；Check that the controller is in good condition to avoid false alarms.

If the screw air compressor is used during excessive fuel consumption (oil running), the possible reasons are:

Oil and gas separator core quality problems or wrong selection, poor oil return, perforated cooler, etc.

There are generally two reasons for this: first.

1. Oil filter plugging; Clause.

Second, there is a problem with the pressure detector.

It may be that the oil is broken and the oil needs to be replaced. When replacing, remember to turn the main machine with a wrench, and then pour the new oil stool inside.

2.It may be that the oil filter is blocked, and then the bypass of the oil filter has been opened, and the oil will go directly to the host without filtering, and the oil should be changed as soon as possible, otherwise it will be easy to damage.

3.There may be a problem with the sensor.

Detection method: remove the oil filter to see the destruction of the ants, if it is too dirty, it is a problem with the oil filter, and then replace it with a new one. Change the oil depending on the situation.

Remove the oil filter, if it is not dirty, it should be a broken pressure sensor.

When the air compressor is running, the overflow of organic oil bend slip back when the air filter, exhaust port or air storage tank is overwaterproof, which is the oil rush phenomenon of the air compressor. The original cause of this problem may be the obstruction of oil return, incomplete cooling of the air compressor, too long running time, too high oil pressure, etc.

When the engine is working, some exhaust gases, water vapor and inadequately burned high-temperature oil and gas will pass through the piston ring gap and flow from the cylinder into the crankcase below. Due to the temperature difference between the crankcase and the engine combustion chamber, the incoming high-temperature gases condense into a liquid and merge into the oil, resulting in the so-called "oil increase". Under normal circumstances, as long as the engine enters the normal hot state, with the increase of oil temperature, the water and fuel mixed into the oil will be heated and vaporized, and then sent back to the intake tract for re-combustion through the forced crankcase ventilation system, and the oil level will naturally return to the normal state.

Therefore, in order to lose what in some cold areas and short-distance vehicles, it is easier to go out of the town and show the phenomenon of "increased engine oil". So all car owners still have to call the travel god to wait for the "oil increase" thing, then if you are really not at ease, you can also mark the dipstick yourself, and after a while to observe it in the same way, you can also exclude.

The reasons for the low oil pressure: 1. The oil volume is insufficient, which reduces the oil volume of the oil pump or does not pump the oil due to air intake, resulting in a decrease in the oil pressure; 2. The engine temperature is too high, which is easy to thin the oil, and a large amount of oil pressure is lost from the mating gap, resulting in a drop in oil pressure; 3. The matching gap between the crankshaft and the large and small tiles is improper, too tight will increase the oil pressure, and too loose will reduce the oil pressure; 4. The blockage of the oil filter and oil suction plate will also reduce the oil pressure; 5. Improper selection of engine oil, if the wrong use or improper selection of the brand, the engine will increase the leakage due to the low viscosity of the oil, so that the oil pressure will be reduced.

Summary. 1. The oil pressure is too low due to insufficient oil quantity; 2. The oil pressure is too low caused by the wear or damage of the oil pump; 3. The engine pressure is too low due to the aging and deterioration of the engine oil caused by the high engine temperature; 4. The oil pressure caused by the blockage of the filter collector is too low; 5. The oil pressure is too low due to damage to the pressure limiting valve or improper adjustment; 6. The oil pressure caused by oil leakage of the oil radiator is too low; 7. The pressure caused by the low viscosity of the oil is too low; 8. The oil pressure is too low caused by the failure of the pressure sensor or the blockage of the oil channel; 9. The pressure caused by the blockage of the oil filter is too low; 10. The oil pressure is too low caused by the increase of the matching clearance between the main bearing and the connecting rod bearing; 11. The oil pressure is too low caused by the abnormal oil pressure display device.

Can you add, I don't quite understand it.
