Through piping model test and pump unit trial it is shown that with the two types of isolating shims the vibration acceleration of the piping system can be reduced evidently.

经管路模型试验和水泵机组试验证明，这两种隔振垫可使管路系统振动加速度级明显下降。

The pump system provides the additional fuel flow necessary to overcome this leanness and maintains smooth engine operation during rapid low-speed acceleration.

加速装置为这种情况提供额外的燃油，从而客服这种问题，使发动机在加速过程中平顺工作。
