一、温升液压传动在能量传递过程中,将产生能量损耗,它由下列几种损失组成:(1) 油液在沿管道流动或流经各种阀时产生的压力损失;(2) 系统中各相对运动的零件因摩擦阻力而引起的机械损失;(3) 泄漏等损耗所造成的容积损失。这些能量损耗转变为热能,使液压系统发热。根据工作条件不同,不同的液压机床所允许的最高油温有所区别。普通与精密机床的油温不应超过60℃,温升小于30℃:高精度机床的油温不应超过
First, the temperature rise Hydraulic transmission in the energy transfer process, there will be energy loss, which consists of the following losses: (1) oil flow along the pipeline or flow through a variety of valve pressure loss; (2) the system In the relative movement of parts due to frictional resistance caused by mechanical loss; (3) leakage and other losses caused by the volume loss. These energy losses translate into heat and heat the hydraulic system. According to different working conditions, different hydraulic machine to allow the maximum oil temperature difference. Ordinary and precision machine tool oil temperature should not exceed 60 ℃, temperature rise is less than 30 ℃: high precision machine oil temperature should not exceed
