螺杆空压机故障的判断与排除方法

2019-12-27  作者:admin    阅读:

1、检查空压机滤清器,如果有损坏、缺陷或不干净的空气滤芯,及时更换损坏部件;检查空压机进气管是否有扭结或变形,保证进气管道具有最低要求的内圈直径(建议15.9毫米以上)。
1. Check the air compressor filter, if there is any damage, defect or unclean air filter element, replace the damaged parts in time; check whether the air inlet pipe of the air compressor is kinked or deformed, and ensure that the air inlet pipe has the minimum required inner ring diameter (more than 15.9mm recommended).
2、检查回油管是否有过多的弯曲、扭结及障碍。建议最小回油管内径为(12毫米)。回油管道必须一直从空压机下降到发动机曲轴箱内。
2. Check the return pipe for excessive bending, kinking and obstructions. The recommended minimum return line inside diameter is (12 mm). The return line must always be lowered from the air compressor into the engine crankcase.
3、检查并测量空压机缸套、活塞环磨损及损坏情况及装配情况,磨损严重的应予更换。
3. Check and measure the wear, damage and assembly of air compressor cylinder liner and piston ring, and replace if the wear is serious.
4、针对空压机的空气冷却部分,要清除在散热片上累积的油污、烟灰或不干净物。发现损坏的零件要更换;检查损坏的散热片,发现损坏的零件要更换。
4. For the air cooling part of the air compressor, the accumulated oil, soot or unclean matters on the heat sink shall be removed. The damaged parts shall be replaced; the damaged fins shall be inspected and the damaged parts shall be replaced.
针对空压机的水冷却部分,要检查适当的冷却管道尺寸(建议管道的最小直径为9.5毫米),检查空压机的冷却剂流通情况,在发动机调节速度时候,最低允许的流量是每分钟5升。如果冷却剂流量缓慢,检查冷却管道和配件积累的锈、扭结和限制因素。
For the water cooling part of the air compressor, check the proper cooling pipe size (it is recommended that the minimum diameter of the pipe is 9.5mm), check the coolant flow of the air compressor, and the minimum allowable flow is 5 liters per minute when the engine adjusts the speed. If the coolant flow is slow, check the cooling pipes and fittings for accumulated rust, kinks and restrictions.
5、检查水温不能超过93℃。检查储气筒上的气阀,保证它们运行正常。建议车辆装备自动排气阀。并在储气筒前适当地配备使空气干燥的空气干燥装置。
5. Check that the water temperature does not exceed 93 ℃. Check the air valves on the air reservoir to ensure they operate normally. It is recommended that the vehicle be equipped with automatic exhaust valve. The air drying device for drying the air shall be properly equipped in front of the air receiver.
6、车辆在刹车没有使用的情况下,泄露每分钟不能超过6.9千帕压力下降,在使用刹车情况下每分钟20.7千帕。如果泄露过多,检查系统漏气并修理。检查卸荷系统是否工作并修复。
6. When the brake is not used, the leakage shall not exceed 6.9 kPa per minute, and the pressure drop shall not exceed 20.7 kPa per minute when the brake is used. If there is too much leakage, check the system for air leakage and repair it. Check the unloading system for operation and repair.
7、测试发动机曲轴箱压力是否过高,更换或修理曲柄轴箱的通风设备。油尺的松动或部分抬起表明曲轴箱的压力有问题。
7. Test whether the engine crankcase pressure is too high, replace or repair the ventilation equipment of the crankcase. A loose or partially raised dipstick indicates a problem with crankcase pressure.
8、检查发动机润滑压力(空压机进油口处),并与额定压力相比较。
8. Check the engine lubrication pressure (at the air compressor oil inlet) and compare it with the rated pressure.
9、更换合格润滑油。
9. Replace qualified lubricating oil.
