don't make the heat pump's piston rod friction reduction device

摘要

the design of the heat pump is not in the lower end of the piston rod, and a low temperature part and a sliding contact with the interior of the groove is sealed by the ball bearing, ball bearing, the end of the rod, linear motion is in point contact with friction is changed. to reduce the friction force of the landslide, the power is generated to greatly reduce the performance did not improve significantly.high speed movement when the heating will not stop system is to solve the problems is to make the characteristics of the heat pump is a device to reduce the friction of the piston rod.
