1、油气别离芯与空气压缩机的配套

1. Matching of Oil and Gas Separation Core and Air Compressor
一般情况下,空气压缩机配套油气别离芯必须选择大于或等于空气压缩机的出气流量,防止在运用过程中吸入的空气中,滤清器过滤不了的细小粉尘将油气别离芯的细别离层阻塞,然后削减油气别离芯的处理流量,造成油气别离芯早期压差过大。配套油气别离芯合适的是在压缩空气出气流量的105%以上来选择。
Generally, the flow rate of oil-gas separation core for air compressor must be greater than or equal to that of air compressor, so as to prevent the fine dust that can not be filtered by filter from blocking the separation layer of oil-gas separation core, and then reduce the flow rate of oil-gas separation core, resulting in excessive pressure difference in the early stage of oil-gas separation core. The most suitable matching oil and gas separation core is to select more than 105% of the compressed air outflow.
2、老化的油的沉淀物、空气中的污染物和磨损的微粒都会影响油气别离芯的运用寿命。用户不同,要求的终究压差也不相同。在实际运用中,压缩机用的油气别离芯的终究压差为0.8~1bar,真空泵为0.5bar.油气别离芯上积累的污物在较高油流量时也会增多,这能够用排污流量来衡量。排污量直接和压缩机的预别离结构规划有关。排污量的值一般在每立方1g左右。所以油气别离芯的运用寿命不能按时刻来衡量,只有用油气别离芯的终究压差来决议寿命。
2. Sediments of aging oil, pollutants in air and wear particles will affect the service life of oil-gas separation cores. Different users require different ultimate differential pressure. In practical application, the ultimate pressure difference of oil-gas separation core for compressor is 0.8-1 bar, and the vacuum pump is 0.5 bar. The accumulated dirt on oil-gas separation core will increase at higher oil flow rate, which can be measured by sewage discharge. The discharge of sewage is directly related to the separation structure planning of compressor. The optimum value of sewage discharge is generally about 1g per cubic meter. Therefore, the service life of oil-gas separation core can not be measured by time, only the ultimate pressure difference of oil-gas separation core can be used to determine the service life.
3、保证油气别离芯经济、长寿命的办法运用
3. Application of methods to ensure economic and long life of oil and gas separation from core
对润滑油的正确保护是保证油气别离芯有一个较满意运用寿命的前提条件。一般来讲,油气别离芯的运用寿命仅受到细别离层上固体颗粒沉淀物(油的氧化物、磨损的颗粒等)的约束,终究导致压差升高。润滑油中的污物可通过替换空气滤清器、机油过滤器和恪守油的替换周期来削减。这样,能够进入油气别离芯上污物保持在少,有利于延伸保护、保养周期。油的选型与油气别离芯的运用寿命有非常大的联系,只能运用那些经批准的、抗老化和对水不敏感的润滑油。抗氧化性差的润滑油不适用,即便工作时刻较短,也会发生一种类似于果冻的粘稠沉淀物,将油气别离芯阻塞。较高的工作温度会加快润滑油的老化,所以也须对冷却风量和冷却器的尘垢引起满足地重视。在替换机油时,须将用过的油完全排掉,以防止新机油遭污染或者新、老机油间不相溶。极少情况下也会出现因为环境空气中夹杂气体杂质而导致润滑油过早老化。

Correct protection of lubricating oil is a prerequisite for ensuring a satisfactory service life of oil-gas separation core. Generally speaking, the service life of oil-gas separation core is only restricted by solid particle precipitates (oil oxides, wear particles, etc.) on the fine separation layer, which eventually leads to the increase of pressure difference. The contamination in lubricating oil can be reduced by replacing air filters, oil filters and scrupulous oil replacement cycles. In this way, the amount of dirt on the oil-gas separation core can be kept at a minimum, which is beneficial to extending the period of protection and maintenance. The type selection of oil is closely related to the service life of oil-gas separation cores, and only those approved, anti-aging and water-insensitive lubricants can be used. Lubricants with poor oxidation resistance are not suitable. Even if they work for a short time, a kind of viscous deposit similar to jelly will occur, which will block the oil and gas separately from the core. Higher working temperature will accelerate the aging of lubricating oil, so it is necessary to pay more attention to cooling air flow and dust of cooler. When replacing oil, the used oil must be completely discharged to prevent new oil from being contaminated or incompatible with old oil. In rare cases, premature ageing of lubricating oils may occur due to the inclusion of gaseous impurities in ambient air.
4、空气压缩机耗油量
4. Oil Consumption of Air Compressor
一些影响空气压缩机储油罐油位的工作条件和临界条件,比如油的挥发过程、预别离和回油系统的效果都会导致短时刻或较长时刻的耗油量增大。例如,回油管阻塞会引起别离出的油积累在油气别离芯的干端,积油的数量级和已积累的油量有关。
Some critical conditions affecting the oil level of air compressor storage tank, such as the volatilization process of oil, the effect of pre-separation and oil return system, will lead to the increase of fuel consumption in a short or longer time. For example, the blockage of the return pipe may cause the separated oil to accumulate at the dry end of the separated core. The magnitude of the accumulated oil is related to the amount of accumulated oil.
储油罐内油位过高也会发生类似的结果,如果在油和气之间暂时或持久不能形成显著的隔离区域,会危害油滴离效果的预分,也会添加油气别离芯下流的空气中的残油率。
Similar results will occur if the oil level in the tank is too high. If there is no significant isolation area between oil and gas temporarily or permanently, it will endanger the pre-separation of oil droplets and also add the residual oil rate in the air where the oil and gas separates from the core.
当油温较低或运用挥发较慢的润滑油时,过量地加油也会导致大量的油泡沫透过油别离芯,油气别离芯势必会添加耗油量。在正常工作温度80℃的情况下,某些型号或商标的润滑油的油烟含量可达10mg/m?
When the oil temperature is low or the volatile oil is used slowly, excessive oil will cause a large number of oil bubbles to leave the core through the oil, and the core will inevitably add fuel consumption. Under the normal working temperature of 80 C, the fume content of some types or trademarks can reach 10 mg/m?
5、储气罐的规划
5. Planning of Gas Storage Tanks
储气罐在空气压缩机内起的效果是贮存压缩机机油;缓冲压缩空气的流速,是油气别离芯前级液态的别离效果。储油罐是油气别离芯处理含油量的决议因素,储油罐的规划合理睬下降压缩空气的含油量,如果规划不合理睬造成压缩空气的含油量增大,一起加大动力的损耗。空气压缩机的设备怎样才干下降动力的损耗,储油罐的规划怎样才算合理?不同的空气压缩机所规划的储油罐都不相同,储油罐的合理规划要注意几点参数。
The effect of air storage tank in air compressor is to store compressor oil, and the effect of cushioning compressed air velocity is to separate oil and gas from the liquid in front of core. Oil storage tank is the decisive factor for oil content treatment by separating oil and gas from core. Oil storage tank planning is reasonable to reduce the oil content of compressed air. If the planning is unreasonable, the oil content of compressed air will increase, together with increasing power loss. How can the equipment of air compressor reduce the loss of power and how can the planning of oil storage tank be reasonable? Different brands of air compressors have different plans for oil storage tanks, and reasonable planning of oil storage tanks should pay attention to several parameters.
⑴了解压缩机头的出气流量和压缩机头需求的喷油流量,参数能够向压缩机头生产商索取。
(1) Understanding the flow rate of the compressor head and the fuel injection flow rate required by the compressor head, parameters can be obtained from the compressor head manufacturer.
⑵压缩空气在7bar压力时进储油罐之前的流速要求是v=15--25m/s的范围内,这时要核算压缩机头到储油罐的管径需求配置多大。
_The velocity requirement of compressed air before entering oil storage tank at 7bar pressure is within the range of v=15-25m/s. At this time, it is necessary to calculate the size requirement of the pipe from compressor head to oil storage tank.
⑶压缩空气在7bar压力时储油罐之内的流速要求是大为V2=0.7M/S,这时要核算进储油罐之前的流速所需求的管径和储油罐之内的流速所需求的储油罐直径。根据带有液态油的压缩空气进入储油罐内所发生的离心力和速度、方向来核算压缩空气含油量。
_When the compressed air pressure is 7 bar, the velocity requirement in the tank is V2=0.7M/S. At this time, the diameter of the pipe required for the flow rate before entering the tank and the diameter of the tank required for the flow rate in the tank should be calculated. The oil content of compressed air is calculated according to the centrifugal force, velocity and direction of the compressed air with liquid oil entering the tank.
⑷储油罐内的压缩空气进入油气别离芯的流速控制在V2=0.7m/s,一起进入油气别离芯的压缩空气的含油量在5~10g/m?之内,能够在回油管上收集油量来测量进油气别离芯的压缩空气含油量。
(5) The flow rate of compressed air entering the oil-gas separation core in oil storage tank is controlled at V2=0.7m/s. The oil content of compressed air entering the oil-gas separation core together is within 5-10g/m? And the oil content of compressed air entering the oil-gas separation core can be collected on the return tubing to measure the oil content of compressed air entering the oil-gas separation core.
⑸核算空气压缩机所需求的喷油量,储油罐内的机油的油面到油气别离芯底部的距离不能小于300mm。不然,会加大油气别离芯的油量处理,造成压缩空气的含油量增大。
(5) Calculate the fuel injection quantity required by the air compressor. The distance between the oil surface of the oil tank and the bottom of the core should not be less than 300 mm. Otherwise, it will increase the oil treatment of oil and gas separated from the core, resulting in an increase in the oil content of compressed air.
