Daily maintenance of air compressor

1、对进气且不足的日常维护处理 

1, the intake and inadequate daily maintenance processing

(1)压缩机转速降低使排气量降低:因空气压缩机的排气量是按一定的海拔高度、吸气温度和湿度设计的，尤其是在高海拔地区安装时一定严格按照使用说明正确安装，隔一段时期(60天左右)应检测一次进气压力和排气量。 

(1) Compressor speed reduces the exhaust capacity: because the air compressor exhaust capacity is designed according to a certain altitude, suction temperature and humidity, especially in high altitude areas must be installed strictly in accordance with the instructions of the use of correct installation, intervals (about 60 days) should be tested intake pressure and exhaust capacity.  

(2)进气滤清器积垢堵塞使排气量减少，要定期清洗滤清器。 

(2) the scale and blockage of the intake filter reduces the amount of exhaust.  

(3)气缸、活塞、活塞环磨损严重、超差、使有关间隙增大，泄漏量增大，影响到了排气量。属于正常磨损时，需及时更换易损件，如活塞环等。属于安装不正确，间隙留得不合适时，应按图纸给予纠正，如无图纸时，可取经验资料。 

(3) The cylinder, piston and piston ring are seriously worn out and out of tolerance, so that the relevant clearance increases, the leakage increases, affecting the exhaust volume. For normal wear, wear parts such as piston rings should be replaced in time. It belongs to incorrect installation and inappropriate clearance, should be corrected according to the drawings, if no drawings, can take experience.  

(4)检查填料函严密程度，填料函本身制造时是否合格;其次在安装时，注意活塞杆与填料函中心的对中性;一般在填料函处加注润滑油，它能起到润滑、密封、冷却的作用。 

(4) Check the tightness of the packing box and whether the packing box itself is qualified when it is manufactured; secondly, pay attention to the neutrality between the piston rod and the center of the packing box during installation; generally fill the packing box with lubricating oil, which can play a role of lubrication, sealing and cooling.  

(5)压缩机吸、排气阀的故障对排气量的影响。这种问题的出现可能是由于一是制造质量问题，如阀片翘曲等;第二是由于阀座与阀片磨损严重而形成漏气。日常检测中应测量阀片的平面度及阀座与阀片的间隙值使其处于正常范围内。 

(5) the influence of compressor's suction and exhaust valves on the discharge volume. This problem may be due to manufacturing quality problems, such as valve slice warping, etc., and the second is due to severe wear and tear between the seat and the valve slice resulting in air leakage. The flatness of the valve sheet and the clearance between the seat and the valve sheet should be measured to keep the valve within the normal range.  

(6)气阀弹簧力与气体力匹配的不好。弹力过强则使阀片开启迟缓，弹力太弱则阀片关闭不及时，这些不仅影响了气量，而且会影响到功率的增加，以及气阀阀片、弹簧的寿命。定期检查弹簧的预紧压力和工作压力。 

(6) the matching between the spring force of the valve and the gas force is not good. If the elasticity is too strong, the valve disc will open slowly. If the elasticity is too weak, the valve disc will not close in time. These not only affect the air flow, but also affect the increase of power, as well as the life of valve disc and spring. Check the pre tightening pressure and working pressure of the spring regularly.  

2、避免声响异常的日常维护要点 

2, to avoid abnormal noise of the daily maintenance points

(1)压缩机安装时注意气缸支腿各处间隙与螺栓受力的情况使之支撑良好。 

(1) when the compressor is installed, attention should be paid to the gap between the legs of the cylinder and the force of the bolt to support it well.  

(2)定期检测压缩机气缸余隙(一般大、中型压缩机的低压气缸的余隙系数值约8%以下，高压气缸的余隙系数值可达12%左右)，定期检测活塞在上下止点的位置，及时调整保证其正常工作。 

(2) Regular detection of compressor cylinder clearance (generally large, medium-sized compressor low-pressure cylinder clearance coefficient value of about 8%, high-pressure cylinder clearance coefficient value of about 12%), regular detection of the piston in the top and bottom stop position, timely adjustment to ensure its normal operation.  

(3)定期检查曲轴箱内曲轴瓦螺、螺帽、连杆螺栓、十字头螺栓的链接情况，及轴径度)、排气阀片、阀弹簧的弹簧力。 

(3) Regularly check the crankcase Bush bolts, nuts, connecting rod bolts, cross head bolts and shaft diameter, exhaust valve discs, valve spring spring force.  

(4)检测出由于大飞轮不平衡引起，平衡铁，对飞轮进行动平衡校正。 

(4) it is detected that the balance iron is caused by the imbalance of the large flywheel and the dynamic balance is corrected for the flywheel.  

3、避免压缩机过热的措施 

3, measures to avoid compressor overheating

(1)检查冷却水供应情况。 

(1) check the supply of cooling water.  

(2)检查油泵油压是否正常，油路有无堵塞，过滤器是否堵塞，并畅通清洗。 

(2) check whether the oil pressure of the oil pump is normal, whether the oil circuit is blocked, whether the filter is blocked or not, and to clean it freely.  

(3)在气阀的发热问题上采用以下方法来解决:先后换过几次气阀，在气阀的安装前都进行过渗漏实验，完全符合安装技术要求，安装到活塞式压缩机上时，发热问题依然存在，以为是弹簧力过大，就对气缸的行程容积做了调整。应用透光法检查了活塞环与气缸的配合情况、应用内径千分尺检查了缸的圆度和圆柱度;曲轴的中心线与活塞杆及滑道的中心线应用拉线法做了全面的测量，结果都符合技术要求。可是缸的温度依然高，对于活塞杆都做了圆柱度、弯曲度的打表校正，最终达到了安装的技术要求。 

(3) Adopt the following method to solve the heating problem of the air valve: change the air valve several times successively, carry on the leakage test before the installation of the air valve, completely conform to the installation technical requirements, when installed on the piston compressor, the heating problem still exists, think that the spring force is too big, adjust the stroke volume of the cylinder. The matching between piston ring and cylinder was checked by transmission method, and the cylinder roundness and cylindricity were checked by inner diameter micrometer. The center line of crankshaft, piston rod and slideway were measured by pulling line method, and the results met the technical requirements. However, the temperature of the cylinder is still high, for the piston rod are done cylindricity, bending of the meter calibration, and ultimately reached the installation of technical requirements.  

4、保证压力正常的日常维护 

4, ensure normal maintenance of pressure.

(1)定期检测气阀，液化气中含有的轻油吸附在气阀上，使气阀弹簧和阀片不能正常工作，影响压缩机的排气量。应定期清洗气阀或更换。 

(1) Regular testing of gas valves, liquefied petroleum gas contains light oil adsorbed on the valve, so that the valve spring and valve disc can not work properly, affecting the discharge of compressor. The valve should be regularly cleaned or replaced.  

(2)安装压缩机时应注意，气环和油环的接口应相错安装，避免泄露液化气。 

(2) when installing the compressor, attention should be paid to that the interface between the gas ring and the oil ring should be installed wrongly, so as to avoid leakage of liquefied petroleum gas.  

(3)活塞在气缸中长期往复运动，液化气中的轻油进人活塞的活塞环槽，牢牢的粘在活塞环上，完全失去了弹性，使活塞环没有密封作用，故应定期清洗或更换活塞环。 

(3) Piston in the cylinder long-term reciprocating movement, liquefied petroleum gas into the piston ring groove, firmly adhered to the piston ring, completely lost elasticity, so that the piston ring has no sealing effect, it should be regularly cleaned or replaced piston ring.  

5、压缩机冷却系统的日常维护 

5. Daily maintenance of compressor cooling system

要达到好的冷却效果，一定要保证冷却水水质在国家规定的标准范围内，以减轻冷却系统结垢、堵塞，同时还必须定期清理冷却系统的污垢，以免减小冷却水的流通面积，妨碍热量交换，降低冷却效能。循环水对金属表面有腐蚀作用，尤其是对冷却列管的腐蚀是比较严重的。平时的处理方法是通过试压检查出泄露部位，采用堵焊列管的方法来处理。目前有些生产厂家采用波纹列管作为2.0MPa压力等级以内换热器的列管，使用时换热效果比较明显，在相同条件下可以减小换热器的体积，并且其自身具有自除垢能力，是一种值得推荐使用的换热。

In order to achieve good cooling effect, it is necessary to ensure that the quality of cooling water is within the limits of national standards to reduce fouling and blockage in the cooling system. At the same time, it is necessary to clean up the fouling of the cooling system regularly so as to avoid reducing the flow area of cooling water, hindering heat exchange and reducing cooling efficiency. Circulating water has a corrosive effect on the metal surface, especially for the cooling pipes. The usual way of processing is to leak out the parts by pressure test and use the method of blocking and welding pipes. At present, some manufacturers adopt corrugated tube as the tube of heat exchanger within 2.0 MPa pressure grade. The effect of heat transfer is obvious when using it. Under the same conditions, the volume of heat exchanger can be reduced, and it has the ability of self-descaling. It is a kind of heat transfer worthy of recommendation.
