动平衡机是进行动平衡较验调整

动平衡机是用于测定转子不平衡的仪器,由于转子上有不平衡离心力,必然造成了转子本身、机械设备的主要零部件等的机械振动。通常机械振动是有弊端的,其主要危害有以下几种:

The dynamic balancing machine is an instrument used to measure the unbalance of the rotor. Because of the unbalanced centrifugal force on the rotor, the mechanical vibration of the rotor itself, the main parts of the mechanical equipment, etc.. Usually the mechanical vibration is a disadvantage, and its main hazards are the following:
1、振动使机器的油管破裂,或者造成动、静接触部分的磨损加剧,并出现了基础部位的松裂,调节器失灵,机器的日常维修变得十分频,更为严重的是促使了机器过早报废。
1, vibration machine broken tubing, or caused by dynamic and static contact parts wear intensifies, and the emergence of the basic parts of the fracture, regulator failure, daily maintenance of machine becomes ten frequency, more make the machine scrapped prematurely is serious.
2、机器的轴承部位受到巨大的动载荷,严重影响其正常运作。
2, the bearing parts of the machine by the huge dynamic load, seriously affect its normal operation.
3、打扰了周围的设备或测试仪器,很有可能使调节设备发生错误操作和机器的保护系统失效,从而造成了测试系统和设备不能正常工作。
3, disturb the surrounding equipment or test equipment, it is possible to make the wrong operation of the equipment and equipment protection system failure, resulting in the test system and equipment can not work.
4、产生噪音,对工作者的身体和心理健康产生了不良影响。
4, noise, the physical and mental health of workers have a negative impact.
假设转子的转速与其轴系本身的频率比较接近时,设备将会出现共振现象。共振的特点是转子的振幅增大很快,机组将剧烈振动导致了机组被破坏。从统计学来看,振动的70~80%是由于转子质量分布的原因引起的。所以,对失衡转子进行平衡校正已成为工业发展不可缺少的部分。
If the rotor speed is close to the frequency of the rotor system, the resonance phenomenon will occur. The characteristic of resonance is that the amplitude of the rotor increases rapidly, and the vibration of the unit will be destroyed. From a statistical point of view, the vibration of 70 ~ 80% is due to the cause of the rotor mass distribution. Therefore, balancing the unbalance rotor has become an indispensable part of industrial development.
我们都知道转子的动平衡是十分重要的,动平衡机就是对转子在旋转状态下进行动平衡较验调整,防止转子的不平衡给机器带来以上危害,从而影响设备的正常运行,更能够减少故障的发生率,大大增加了机器设备的使用寿命。
We all know that the rotor dynamic balance is very important, is the rotor dynamic balancing machine under rotating state dynamic balance checking adjustment, not to bring more harm to prevent the machine balance of the rotor, thus affecting the normal operation of the equipment, it can reduce the incidence of failure, greatly increasing the service life of the machine.
