分析了TDF120-250×9型渣油泵平衡盘频繁失效的原因,提出了一种新型的动力楔平衡盘结构,试用情况表明.该新型平衡盘可有效避免平衡盘与平衡盘座贴合而造成的严重磨损,平衡盘使用寿命显著延长;同时又具有逆流泵送作用,减小了泄漏量,节约了能源。
The reason of the frequent failure of balancing disc of TDF120-250 × 9 type oil pump was analyzed and a new type of dynamic wedge balancing disc structure was put forward.The experimental results show that the new balancing disc can effectively avoid the fitting of balance disc and balance disc seat Of the serious wear and tear, significantly prolong the service life of the balance plate; at the same time, it has the function of countercurrent pumping, reducing the amount of leakage and saving energy.
