我矿使用的一台PYZ—900圆锥破碎机原来是用油泵直接供油到各润滑点进行润滑,油泵随主机运转而运转。油压既不能低于0.5(公斤/厘米~2)也不能高于2(公斤/厘米~2),油温不得超过60℃。为了保证这些条件,配置了一套复杂的电器保护装置和仪表。当供油系统发生故障时,它即发出警报,停车。这种润滑供油系统有以下缺点:油压不易控制,油压往往过高,油被挤到机子外面;供油均匀
A PYZ-900 cone crusher used by mine used to pump oil directly to each lubrication point for lubrication. The oil pump runs with the host machine. Oil pressure can not be less than 0.5 (kg / cm ~ 2) nor higher than 2 (kg / cm ~ 2), the oil temperature shall not exceed 60 ℃. In order to ensure these conditions, equipped with a complex set of electrical protection devices and meters. When the fuel system fails, it alerts and stops. The lubrication of oil supply system has the following disadvantages: hydraulic pressure is not easy to control, the hydraulic pressure is often too high, the oil is squeezed outside the machine; uniform fuel supply
