空压机油耗过高八大因素盘点

油气分离罐设计不规范

Non standard design of oil and gas separation tank
有部分空压机厂商,在设计油气分离罐时,初级分离系统设计不合理,初级分离效果不理想,使进油分前的油雾浓度含量很高,油分负荷过重,处理能力不足,导致油耗过高。买了这样的产品,操作技术再好都没办法了!
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.
2加油过多
2 overrefueling
加油量超过正常油位,部分机油随气流带走,导致耗油量过大。这简单的原因,有些人就是粗枝大叶不注意。
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用气量大,超负荷低压使用
3 use high gas quantity, overload low pressure use
负荷低压使用是指用户使用空压机时,排气压 力并未达到空压机本身的额定工作压力,但基本能满足某些企业用户的用气要求,例如:企业用户增加了用气设备,用气量增大,使空压机排气量与用户的用气量无法达到平衡,假设空压机额定排气压力8kg/c㎡,但实际使用时压力只有5kg/c㎡甚至更低,这样空压机长期处于负荷运行状态,无法达到机器的额定压力值,导致耗油量增大,其原因是在排气量不变的条件下,油气混合物经过油分时流速加快,油雾浓度过高,使油分负荷加重,最终导致耗油量大。
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回油管路堵塞
4 back oil pipeline blockage
当回油管路(包括回油管上的单向阀及回油滤网)有异物堵塞时,分离后凝聚在油分底部的机油就无法回到机头,已经凝聚的油滴又被气流吹起,随着分离后的空气一起被带走。这些异物通常是由安装时掉落的固体杂质造成。
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回油单向阀损坏
5 return oil one-way valve damage

若回油单向阀损坏(由单向通变成双向通),停机后油分罐内压则会将大量的机油通过回油管倒回油分内部,下次机器运行时,油分内部的机油将无法及时吸回机头,导致部分的机油随着分离后的空气跑到空压机外(此种情况常见于未装置油路截止阀和机头排气出口单向阀的机器)。
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.
6回油管安装不当
Improper installation of the 6 oil pipe
在更换、清洗、维修空压机时,回油管未插到油分底部(参考:距油分底部弧心1~2mm较好),导致分离出来的机油无法及时回到机头,积聚的机油会随着压缩空气一起跑出去。
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最小压力阀故障
7 minimum pressure valve failure
若最小压力阀的密封处有泄漏点或最小压力阀提前开启(因各厂家设计开启压力各有不同,通常范围在3.5~5.5kg/c㎡之间),那么机器在运行初期建立油气罐压力时间就会增长,此时处于低压状态的气体油雾浓度高,通过油分时流速快,油分负荷加重,分离效果降低,导致耗油量大。
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.
