      1、油氣別離芯與空氣壓縮機的配套

      1. Matching of Oil and Gas Separation Core and Air Compressor
      一般情況下,空氣壓縮機配套油氣別離芯必須選擇大于或等于空氣壓縮機的出氣流量,防止在運用過程中吸入的空氣中,濾清器過濾不了的細小粉塵將油氣別離芯的細別離層阻塞,然后削減油氣別離芯的處理流量,造成油氣別離芯早期壓差過大。配套油氣別離芯最合適的是在壓縮空氣出氣流量的105%以上來選擇。
      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、空氣中的污染物和磨損的微粒都會影響油氣別離芯的運用壽命。用戶不同,要求的終究壓差也不相同。在實際運用中,壓縮機用的油氣別離芯的終究壓差為0.8~1bar,真空泵為0.5bar.油氣別離芯上積累的污物在較高油流量時也會增多,這能夠用排污流量來衡量。排污量直接和壓縮機的預別離結構規劃有關。排污量的最佳值一般在每立方1g左右。所以油氣別離芯的運用壽命不能按時刻來衡量,只有用油氣別離芯的終究壓差來決議壽命。
      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、保證油氣別離芯經濟、長壽命的辦法運用
      3. Application of methods to ensure economic and long life of oil and gas separation from core
      對潤滑油的正確保護是保證油氣別離芯有一個較滿意運用壽命的前提條件。一般來講,油氣別離芯的運用壽命僅受到細別離層上固體顆粒沉淀物(油的氧化物、磨損的顆粒等)的約束,終究導致壓差升高。潤滑油中的污物可通過替換空氣濾清器、機油過濾器和恪守油的替換周期來削減。這樣,能夠進入油氣別離芯上污物保持在最少,有利于延伸保護、保養周期。油的選型與油氣別離芯的運用壽命有非常大的聯系,只能運用那些經批準的、抗老化和對水不敏感的潤滑油??寡趸圆畹臐櫥筒贿m用,即便工作時刻較短,也會發生一種類似于果凍的粘稠沉淀物,將油氣別離芯阻塞。較高的工作溫度會加快潤滑油的老化,所以也須對冷卻風量和冷卻器的塵垢引起滿足地重視。在替換機油時,須將用過的油完全排掉,以防止新機油遭污染或者新、老機油間不相溶。極少情況下也會出現因為環境空氣中夾雜氣體雜質而導致潤滑油過早老化。

      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、空氣壓縮機耗油量
      4. Oil Consumption of Air Compressor
      一些影響空氣壓縮機儲油罐油位的工作條件和臨界條件,比如油的揮發過程、預別離和回油系統的效果都會導致短時刻或較長時刻的耗油量增大。例如,回油管阻塞會引起別離出的油積累在油氣別離芯的干端,積油的數量級和已積累的油量有關。
      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.
      儲油罐內油位過高也會發生類似的結果,如果在油和氣之間暫時或持久不能形成顯著的隔離區域,會危害油滴離效果的預分,也會添加油氣別離芯下流的空氣中的殘油率。
      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.
      當油溫較低或運用揮發較慢的潤滑油時,過量地加油也會導致大量的油泡沫透過油別離芯,油氣別離芯勢必會添加耗油量。在正常工作溫度80℃的情況下,某些型號或商標的潤滑油的油煙含量可達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、儲氣罐的規劃
      5. Planning of Gas Storage Tanks
      儲氣罐在空氣壓縮機內起的效果是貯存壓縮機機油;緩沖壓縮空氣的流速,是油氣別離芯前級液態的別離效果。儲油罐是油氣別離芯處理含油量的決議因素,儲油罐的規劃合理睬下降壓縮空氣的含油量,如果規劃不合理睬造成壓縮空氣的含油量增大,一起加大動力的損耗??諝鈮嚎s機的設備怎樣才干下降動力的損耗,儲油罐的規劃怎樣才算合理?不同品牌的空氣壓縮機所規劃的儲油罐都不相同,儲油罐的合理規劃要注意幾點參數。
      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了解壓縮機頭的出氣流量和壓縮機頭需求的噴油流量,參數能夠向壓縮機頭生產商索取。
      (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壓縮空氣在7bar壓力時進儲油罐之前的流速要求是v=15--25m/s的范圍內,這時要核算壓縮機頭到儲油罐的管徑需求配置多大。
      _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壓縮空氣在7bar壓力時儲油罐之內的流速要求是大為V2=0.7M/S,這時要核算進儲油罐之前的流速所需求的管徑和儲油罐之內的流速所需求的儲油罐直徑。根據帶有液態油的壓縮空氣進入儲油罐內所發生的離心力和速度、方向來核算壓縮空氣含油量。
      _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儲油罐內的壓縮空氣進入油氣別離芯的流速控制在V2=0.7m/s,一起進入油氣別離芯的壓縮空氣的含油量在5~10g/m?之內,能夠在回油管上收集油量來測量進油氣別離芯的壓縮空氣含油量。
      (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核算空氣壓縮機所需求的噴油量,儲油罐內的機油的油面到油氣別離芯底部的距離不能小于300mm。不然,會加大油氣別離芯的油量處理,造成壓縮空氣的含油量增大。
      (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.
