www.878365.com机场性的维修主要是因为这些?

(1)环境通风散热状况不良。www.878365.com周围环境影响散热主要有三种状况:一是离墙类障碍物过近;二是www.878365.com邻近有其他热源,三是运行时前门及边门敞开,电扇无法形成强气流。

(1) Poor ventilation and heat dissipation in the environment. There are three main situations of environmental impact and heat dissipation around the air compressor: one is too close to wall obstacles; the other is that the air compressor is adjacent to other heat sources; the third is that the front door and side door are open when the air compressor is running, and the fan can not form strong air flow.
(2)散热器堵塞。当www.878365.com周围环境尘埃较多时,长时间运行就形成散热器表面黏附一层粉尘或油泥,其内部铜管也容易因油垢积累而堵塞,然后影响散热效果。
(2) The radiator is blocked. When there is more dust around the air compressor, a layer of dust or sludge adheres to the radiator surface for a long time, and the copper pipe inside the radiator is easy to be blocked by the accumulation of oil scale, which then affects the heat dissipation effect.
(3)滤油器太脏。该机有3个并排的滤油器,当其太脏时因阻力油无法按正常流量进入紧缩机,紧缩时机因冷却润油不足而迅速升温。当进出油压差超越0.18MPa时就需替换滤芯。
(3) The oil filter is too dirty. The machine has three side-by-side oil filters. When it is too dirty, the resistance oil can not enter the compressor according to the normal flow rate. When the compressor is too dirty, the temperature rises rapidly because of insufficient cooling and lubricating oil. When the oil pressure difference between inlet and outlet exceeds 0.18 MPa, the filter element needs to be replaced.
(4)冷却油油面过低。当冷机检查时,油面低于检视管下端时应立即进行弥补。
(4) Cooling oil level is too low. When the oil level is lower than the lower end of the inspection tube, it should be compensated immediately when the refrigerator is inspected.

(5)油标号低或油质差。该机采用生产厂商的专用紧缩机油,用其他低标号或残次油时会回黏度及比热达不到标准形成温度过高。
(5) Low oil label or poor oil quality. The machine uses the special compressor oil of the manufacturer. When using other low-grade or residual oil, the back viscosity and specific heat can not reach the standard and the forming temperature is too high.
(6)电扇胶带断裂或松懈。当胶带断裂时www.878365.com工作5min左右就会因温度过高而自动停机,如胶带太松会打滑,使电扇转速降低,然后影响散热,此时,应替换或调整电扇胶带的松紧度。
(6) Fracture or loosening of fan tape. When the tape breaks, the press will automatically stop working for about 5 minutes because of the high temperature. If the tape is too loose, it will slip, which will reduce the speed of the fan, and then affect the heat dissipation. At this time, the tightness of the tape should be replaced or adjusted.
(7)断油阀失灵。在滤油器与紧缩机之间有一个断油阀,当断油阀无法开启时,因无油润滑及冷却,紧缩机发动后温度迅速上升,大约1min左右就会自动停机。拆下紧缩机主机排气端的温度塞,会发现塞上干燥无油,亦会有青烟从孔中飘出。打开www.878365.com底部检修孔,拆下断油阀,用手指轻轻拨动阀杆,看能否前后推进和能否轻松复位。如拨动或回位困难,则需进一步将断油阀解体。假如阀杆或阀孔有油垢,则需用细砂纸打磨直至能轻松滑动;假如绷簧拆断或有异物卡信也会影响阀杆运动,此时需替换绷簧或清洗绷簧及绷簧座。
(7) Failure of oil shutoff valve. There is an oil shut-off valve between the oil filter and the compressor. When the oil shut-off valve cannot be opened, the temperature of the compressor rises rapidly after starting because of no oil lubrication and cooling, and the compressor will stop automatically about 1 minute. When you remove the temperature plug at the exhaust end of the compressor main engine, it will be found that the plug is dry and oil-free, and there will be smoke coming out of the hole. Open the bottom overhaul hole of the air compressor, remove the oil break valve, and gently move the valve stem with your finger to see if it can be pushed forward and reset easily. If it is difficult to move or return, the oil shut-off valve needs to be further disintegrated. If there is greasy dirt in the stem or hole, fine sandpaper should be used to polish the stem until it can slide easily. If the tension spring is broken or foreign body cards can also affect the stem movement, it is necessary to replace the tension spring or clean the tension spring and the tension spring seat.
(8)www.878365.com无压力空气排出。
(8) Pressure-free air discharge from air compressors.
毛病原因:1、www.878365.com松压阀卡滞。阀片变形或断裂;2、进、排气口积碳过多。
Causes of hair: 1. Air compressor pressure relief valve stuck. Deformation or fracture of valve plate; 2. Excessive carbon deposition at inlet and exhaust ports.
毛病的判断与扫除方法:1、检查松压阀组件,清洗、替换失效件;2、拆检缸盖,检查阀片,替换变形、断裂的阀片;3、拆检缸盖,整理阀座板、阀片。
Defect judgment and cleaning methods: 1. Check the loose pressure valve assembly, clean and replace the failure parts; 2. Remove and inspect the cylinder head, check the valve piece, replace the deformed and broken valve piece; 3. Remove and inspect the cylinder head, tidy up the valve seat plate and valve piece.
(9)空气压为不足毛病现象:在发动机工作,www.878365.com向储气罐充气的状况下,气压表指示气压达不到起步压力值。
(9) The phenomenon of insufficient air pressure: when the engine works and the air compressor inflates into the storage tank, the barometer indicates that the pressure can not reach the starting pressure value.
