仿苏??-18型和??-125型齿轮式油泵,在现代化的工矿企业中,常被用来作液压控制、循环给油和制动装置等动力设备。该种型号油泵的特点是:体积小、排油量大、维护费用低。但它存在的主要缺点是轴颈漏油严重。虽然在油泵端盖上装有油封毡垫,由于装配或磨损等原因,新油泵平均经过一个月时间的使用,漏油现象日越显著,这样不但浪费大量油料(一般情况每台油泵每月轴颈漏油损失6公斤左右),同时给设备维护整洁工作带来很大困难。大冶铁矿针对上述缺点,组织有老工人和技术员参加的三结合小组,进行了研究和试验,终于在不影响油泵原来工作特性和不增添其它附属装置的情况下,消除了轴颈漏油的毛病,改进和装配方法如下(见下图):
Imitation Su ?? - 18 and ?? - 125 gear pump, in the modern industrial and mining enterprises, often used for hydraulic control, circulation, oil and brake devices and other power equipment. This type of pump is characterized by: small size, large displacement, low maintenance costs. But its main drawback is the serious oil spill. Although the oil cap is fitted with oil seal felt, the new oil pump will have an average of more than one month due to assembly or abrasion, which results in more and more oil spills. This will not only waste a lot of oil (usually, the monthly journal of each oil pump Leakage loss of about 6 kg), while bringing great difficulties to equipment maintenance and cleanliness. Daye Iron Mine in response to the above shortcomings, the organization of the old workers and technicians to participate in the three combination group, conducted a study and test, and finally did not affect the original pump performance and do not add other ancillary equipment, eliminating the shaft leakage Problems, improvements and assembly methods are as follows (see below):
