Because the fluid powering the gripper is also used to cool it down, it takes more pressure to power movement at higher temperatures.
因为为夹具提供动力的流体也用于冷却它,所以在更高的温度下需要更大的压力来驱动运动。

Fluid power
Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine.
