随着工程机械的发展,CB-E系列齿轮泵应用日益广泛。但该泵使用中的一个很大缺点是橡胶油封寿命太低,有的甚至仅能使用几十个小时。如果配件供应不及时,就会使该泵因无油封而被搁置。为解决这一问题,我们利用我厂库存的PD35×55×12油封(标准的是PD35×56×12)对该泵进行了改装,具体方法如下: 如图示,利用原泵盖1配做铸铁套2,铁套高25毫米,与泵盖的配合过盈为0.03～ With the development of construction machinery, CB-E series gear pumps are increasingly used. However, one of the major drawbacks of using this pump is that the life of the rubber seal is too low, and some of them can only be used for tens of hours. If the supply of spare parts is not timely, the pump will be put on hold because of no oil seal. To solve this problem, we used the PD35×55×12 oil seal (standard is PD35×56×12) in our factory to modify the pump. The specific method is as follows: As shown in the figure, use the original pump cover to match Cast iron sleeve 2, iron sleeve height 25 mm, with the pump cover with an interference of 0.03 ~
