使用齿轮油泵注意事项简要分析Brief analysis of precautions for using gear oil pump

　　齿轮油泵适用于输送多种有润滑性的液体，温度不高于70℃，如需高温200℃，可配用以实际报告为主材料，粘度为5×10-5～1，5×10-3m2/S。本泵不适用于输送腐蚀性的、含硬质颗粒或纤维的、高度挥发或闪点低的液体。

　　1、经常加脂，电动油桶泵为运转，润滑脂易于挥发，故需要使轴承处的润滑能保持清洁，并注意添换。

　　2、齿轮油泵经常检查维修，电动油桶泵应经常检查，维修，须检查电源线：内接线，插头，开关是否良好，绝缘电阻是否正常，刷尾座是否松动，换向器与电刷接触良好，电枢绕级扩定子绕组是否是有适中断路现象，轴承及转动零件是否的损坏等等。

　　3、保存好每零件和调换相同零件，在拆检齿轮油泵时，应保存好每个零件，要注意隔爆零件的隔爆面、拉毛包括绝缘衬垫及套管不能使其损伤，如有损坏，需要调换上新的相同零件，不得采用低于原材料性能的代用材料或原有规格不符的零件，装配时应将零件按原先位置装好，不能遗漏。

　　4、齿轮油泵注意绝缘电阻，长期搁置不用的或在潮湿环境中使用的电动抽液泵，使用前需要用500伏兆欧表测量绕组的绝缘电阻。如绕组与电机壳间绝缘电阻小于7兆欧时，需要对绕组进行干燥处理。

　　5、注意保存电动抽油泵应放于干燥，清洁和没有腐蚀性气体的环境中。

　　（1）齿轮油泵使用禁忌，从齿轮油泵维修和养护的角度看。在使用中，严禁向齿轮油中加入柴油等进行稀释，也不要因影响冬季起步而烘烤后桥，变速器，以免齿轮油严重变质。如果出现这种情况，应换用低粘度的多级齿轮油。

　　（2）信守合同能用普通齿轮油泵代替准双曲面齿轮油。

　　（3）不要误认高粘度齿轮油的润滑有力的。使用粘度太高标号的齿轮油，将会使燃料消耗显著增加，也不利于齿轮的用心服务及维修养护，特别是对高速轿车影响大的，应尽可能使用合适的多级齿轮油。

　　（4不要混淆机油和齿轮油的SAE分类标号。在计算标准中为避免混淆，规定为高的分级标号用在齿轮油上，低的分级标号用于发动机润滑油。但对于旧牌号齿轮油分级号较低。应注意齿轮油泵和发动机油粘度级别并无联系，同型号不能互用。切不可将齿轮油当发动机油使用，否则发动机将会发生烧瓦，粘缸和烧结活塞顶等严重事故。

　　（5）合理使用齿轮油泵有利于齿轮维修保养。齿轮油的使用时间较长，如使用单级油，在换季维护时换用不同的粘度标号。放出的旧油如不到换油期限，可在再次换油时加车使用。旧油应妥善保管，严性能稳定分，机械杂质和废油污染。

　　（6）加油量应适当。油量应适当，不可过多也不可过少。过多不仅增加搅油阻力和燃料消耗，而且有可能齿轮油经后桥壳混入制动鼓（如果密封不良）造成制动失灵;过少会使润滑不良，温度过高，加速齿轮磨损，会对齿轮维修造成不利影响。齿轮油面一般应加到与齿轮箱加油口下缘平齐，且应经常检查各齿轮油箱是否渗漏，并保持各油封，衬垫完好。

　　（7）适时换油。应按规定换油指标换用新油，无油质分析手段时，可按规定期限换油。

　　Gear oil pump is suitable for conveying a variety of lubricating liquids. The temperature is not higher than 70 ℃. If the high temperature is required to be 200 ℃, it can be equipped with materials based on actual reports, with a viscosity of 5 × 10-5～1，5 × 10-3m2/S。 The pump is not suitable for conveying corrosive, hard particles or fibers, highly volatile or low flash point liquids.

　　1. Often add grease. The electric oil drum pump is running, and the grease is easy to volatilize. Therefore, it is necessary to keep the lubrication at the bearing clean and pay attention to adding and replacing.

　　2. The gear oil pump shall be inspected and maintained frequently, and the electric oil drum pump shall be inspected and maintained frequently. The power cord shall be checked: whether the internal wire, plug and switch are in good condition, whether the insulation resistance is normal, whether the brush tail seat is loose, whether the commutator is in good contact with the brush, whether the armature winding is expanded, whether the stator winding is moderately open circuit, whether the bearing and rotating parts are damaged, etc.

　　3. Keep each part and replace the same part. When disassembling and inspecting the gear oil pump, keep each part well. Pay attention to the flameproof surface and roughening of the flameproof parts, including the insulating gasket and casing. If they are damaged, they need to be replaced with new identical parts. Substitute materials lower than the performance of raw materials or parts inconsistent with the original specifications shall not be used. During assembly, the parts shall be installed according to the original position without omission.

　　4. Pay attention to the insulation resistance of gear oil pump. For electric liquid extraction pump that is not used for a long time or used in humid environment, it is necessary to measure the insulation resistance of winding with 500V megohmmeter before use. If the insulation resistance between the winding and the motor shell is less than 7 megohm, the winding needs to be dried.

　　5. Note that the electric oil well pump should be stored in a dry, clean and non corrosive environment.

　　(1) The use of gear oil pump is taboo, from the perspective of gear oil pump maintenance and maintenance. During use, it is strictly prohibited to add diesel oil to the gear oil for dilution, and do not bake the rear axle and transmission because it affects the starting in winter, so as to avoid serious deterioration of the gear oil. If this happens, use low viscosity multi-stage gear oil instead.

　　(2) Abiding by the contract can replace hypoid gear oil with ordinary gear oil pump.

　　(3) Do not mistake high viscosity gear oil for powerful lubrication. The use of gear oil with too high viscosity grade will significantly increase the fuel consumption and is not conducive to the careful service and maintenance of gears. Especially for high-speed cars, appropriate multi-stage gear oil should be used as much as possible.

　　(4) do not confuse the SAE classification number of engine oil and gear oil. In the calculation standard, in order to avoid confusion, it is specified that the high classification number is used for gear oil and the low classification number is used for engine lubricating oil. However, the classification number of old brand gear oil is lower. It should be noted that the viscosity grade of gear oil pump and engine oil is not related, and the same model cannot be used with each other. Gear oil must not be used as engine oil, otherwise the engine will burn, Serious accidents such as sticking cylinder and sintering piston crown.

　　(5) Rational use of gear oil pump is conducive to gear maintenance. The service time of gear oil is long. If single-stage oil is used, different viscosity grades shall be used during seasonal maintenance. If the oil is not replaced, it can be refilled when the oil is replaced. The used oil shall be kept properly, and its performance shall be strictly separated from mechanical impurities and waste oil pollution.

　　(6) The amount of refueling should be appropriate. The amount of oil should be appropriate, neither too much nor too little. Too much oil will not only increase the oil stirring resistance and fuel consumption, but also the gear oil may be mixed into the brake drum through the rear axle housing (if the seal is poor), resulting in brake failure; Too little will cause poor lubrication, too high temperature, accelerate gear wear, and adversely affect gear maintenance. Generally, the gear oil level shall be flush with the lower edge of the oil filler of the gear box, and the gear oil tank shall be regularly checked for leakage, and all oil seals and gaskets shall be kept intact.

　　(7) Change the oil timely. The oil shall be replaced with new oil according to the specified oil change index. If there is no oil quality analysis means, the oil can be replaced according to the specified period.
