Non standard design of oil and gas separation tank
In the design of oil and gas separation tank, the design of the primary separation system is unreasonable, the primary separation effect is not ideal, the concentration of oil mist before the oil entry is high, the oil load is too heavy and the treatment ability is insufficient, which leads to the high oil consumption. If you buy such a product, there will be no way to operate it.
The amount of refueling exceeds the normal oil level, and some oil is carried away with the airflow, resulting in excessive fuel consumption. The simple reason is that some people are careless and careless.
3 use high gas quantity, overload low pressure use
The use of the load low pressure means that when the user uses air compressor, the exhaust pressure does not reach the rated working pressure of the air compressor itself, but it can basically meet the requirements of some enterprise users, for example, the enterprise users increase the gas use equipment and increase the gas quantity, so that the air compressor exhaust volume and the user's gas consumption can not reach the balance. The rated exhaust pressure of the air compressor is 8kg/c, but the actual pressure is only 5kg/c and even lower, so the air compressor is in a long load running state and can not reach the rated pressure value of the machine, which leads to the increase of the fuel consumption. The reason is that the flow velocity of oil and gas mixture is quicker when the oil and gas mixture is passed through the oil separation condition. Fog concentration is too high, so that the load of oil increases, resulting in a large amount of fuel consumption.
4 back oil pipeline blockage
When the return oil line (including the one-way valve and the oil back filter on the oil recovery pipe) has a foreign body blockage, the oil condenses at the bottom of the oil separation can not return to the head, and the condensed oil drops are blown up by the air flow, and the air is taken away with the separated air. These foreign bodies are usually caused by solid impurities falling during installation.
5 return oil one-way valve damage
If the return oil one-way valve is damaged (from one way through to bi-directional), the pressure in the oil tank will reverse the oil inside the oil pipe after the shutdown, and the oil in the oil division will not be sucked back to the head in time when the next machine runs, so that some oil will run out of the air compressor with the air after the separation (this case). Commonly used in machines not equipped with oil circuit cut-off valve and head outlet outlet check valve.
Improper installation of the 6 oil pipe
When replacing, cleaning and repairing the air compressor, the oil pipe is not inserted into the bottom of the oil (Reference: 1~2mm is better from the bottom arc center of the oil division). The oil will not return to the head in time, and the accumulating oil will run out with the compressed air.
7 minimum pressure valve failure
If there is a leak point or a minimum pressure valve in the seal of the minimum pressure valve, the pressure time of the tank will increase at the beginning of operation, and the gas oil mist in the low pressure state is high at this time, and the time flow through the oil separation flow is achieved. Fast, the load of oil is heavier, the separation effect is reduced, resulting in large oil consumption.
