Roll mill system analysis of the internal leakage

Roll mill system of leakage is divided into internal leakage power components, control components of leakage and leakage of actuators.
power components of leakage: power components ( Generally refers to pump or laser motor) Inside leaking, mainly by the moving parts ( Such as blade and the inner wall of the pump, etc. ) Wear cause with each other, the vane pump, for example, once the blade and the walls of the pump or with grilled with flow wear after reaching a certain degree, part of the laser oil will wear down the gap of direct outflow, rather than through the formation pressure cavity movement of flow. In this way, can output by a motor sports will be a lot of land is converted into heat energy, make the system oil temperature rise rapidly. The fault is characterized by: the oil temperature and its temperature is more noticeable dynamic element, at the same time the system pressure drop significantly.
control components of leakage: the inside leaking control element is divided into a single control valve inside leaking and a set of valve for pressure regulating improper drainage in two. Single control valve inside leaking is commonly caused by the wear and tear of parts, valve itself will appear the phenomenon of temperature rise sharply, easy to judgment; Pressure regulating improper inner-leakage is relatively difficult to determine, need to undertake the analysis of the system.
execute component of leakage, leakage of executive element, the generally easier to judge, executive components tend to be accompanied by a dramatic increase in temperature and a reduction in the ability to work. To this point in the motor and the laser is an obvious on the cylinder. This article reprinted from laser cutting machine
