TDF120-250×9型渣油泵平衡盘改造

Modification of Balancing Discin TDF120-250 ×9 Type Residual Oil Pump

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 causes why the failure occurs frequently in the balancing disc of the TDF120 - 250 × 9 type residual oil pump were analyzed. And a new type of balancing disk with the structure design on the principle of fluid dynamic wedge was developed. The test run showed that the new type of balancing disc can efficiently prevent the disc from being in contact with the seat so as to avoid the serious wear and prolong the service life of the balancing disk, and it also can reduce the leakage and save the energy due to its upstream pumping function. .
