Due to highspeed, high viscosity pump inside the rotor is barely formed when running idle, surrounding medium by sliding, cause not feeding, or flow rate is small.
The efficiency of steering pump of port tractor lost very heavy when engine was in highspeed.
港口牵引车液压系统中的转向泵在发动机高速状态时的能量损失较大。

Impurity pump mechanical seal after static test, the operation of high-speed rotation of the centrifugal force generated will inhibit the leakage of media.
