Based on the simulation data, the effects of clearances, damping coefficient and the rotation speed on the dynamic behaviors are studied: compared with ideal mechanisms, mechanisms with clearances are less stable; as for mechanisms with clearances, when the crank rotates at the speed of 100rad/s, the actual clearances are always above the radium of clearances, axle pin and axle cover keep contact throught the rotation; when the crank rotates at the speed of 20rad/s, mechanisms are in an unstable state, at an angle of about 300, the actual clearances are below the radium of clearances, pairs lose contact, which results in collision between them; with the speed of 20rad/s, when damping coefficient is assumed 175Ns/m, distinct separation and collision happen between pairs; when damping coefficient is assumed 220Ns/m, separation and collision are controlled.

在含间隙机构中，当曲柄以100rad/s转动时，运动副间隙始终大於半径间隙，轴销与轴套始终保持连续接触；当曲柄以低速20rad/s转动时，系统处於极不稳定的震荡状态，在转至300°左右时，运动副间隙小於半径间隙，脱离接触，发生明显的分离碰撞现象。在含间隙机构中，曲柄以低速20rad/s转动，当取法向阻尼系数为175Ns/m时，副元素发生明显的分离碰撞现象；当取法向阻尼系数为220Ns/m时控制了副元素的分离，副元素一直处於连续接触状态。

The Circulation-hydrogenation Compressor Model BLC-305/A is an important equipment with Hydrogenation devices, which is imported by Lanzhou Petrochemical Company Refinery. Due to high-speed rolling periodically, the spare parts of this compressor, to a varying extent, show a lot of signs of wear and tear. Especially, the axle sleeve of the rotor axle of the compressor is so worn to the greatest degree that its work efficiency decreases by a big margin. Machinery Factory of Lanzhou Petroleum Processing and Chemical Complex has undertaken this task to repair the rotor.

The failure characteristics of large pump units are that the influence is great, the reasons are complicated, it is difficult to observe and the failure rate is hard to determine. The main failures of large pump units are as follows: burn out of thrust bearing liner of the motor, failure of stator and rotor coil insulation of the motor, wear-and-tear of guiding bearing and shaft neck of the pump, breakdown of adjusting mechanism of the pump blade, and pump cavitation. The reasons of main failures are studied in design, structures, installation and operation etc.
