国内有许多墙地砖生产厂家采用Welko公司生产的HYDRA800型压机。该机配用的是恒压变量径向柱塞油泵.笔者对延长油泵使用寿命有几点体会.供同仁参考. 1、液压系统的外泄和内泄会加速损坏油泵,使其寿命降低.因此应该从解决系统内、外泄漏着手,这是因为泄漏增大了油泵的负荷. Many domestic tile manufacturers use HYDRA800 presses produced by Welko. The machine is equipped with a constant pressure variable radial piston oil pump. The author has several experience for extending the service life of the pump. For colleagues reference. 1, the hydraulic system leakage and internal leakage will accelerate the damage to the oil pump to reduce its life. Therefore, we should start from solving the problem of leakage inside and outside the system. This is because leakage increases the load of the oil pump.
