5．振动和噪声
振动和噪声是同时出现的。它们不仅对机器的操作者造成危害，也对环境造成污染。
(1)机械振动和噪声
如泵轴和电机轴不同心或**死，旋转轴的轴承、联轴节损伤，弹性垫破损和装配螺栓松动均会产生噪声。对于高速运转或传输大能量的泵，要定期检查，记录各部件的振幅、频率和噪声。如泵的转动频率与压力阀的固有频率相同时，将会引起共振，可改变泵的转速以消除共振。
(2)管道内液流产生的噪声
进油管道太细、进油滤油器通流能力过小或堵塞、进油管吸入空气、油液豁度过高、油面过低吸油不足和高压管道中产生液击等，均会产生噪声。因此，必须正确设计油箱，正确选择滤油器、油管和方向阀。
6．液压泵过热
液压泵过度发热有两个原因，一是机械摩擦生热。由于运动表面处于干摩擦或半干摩擦状态，运动部件相互摩擦生热。二是液体摩擦生热。高压油通过各种缝隙泄漏到低压腔，大量的液压能损失转为热能。所以正确选择运动部件之间的间隙、油箱容积和冷却器，可以杜绝泵的过度发热和油温过高的现象。另外，回油过滤器堵塞造成回油背压过高，也会引起油温过高和泵体过热。

5. Vibration and noise


Vibration and noise occur simultaneously. They not only do harm to the operator of the machine, but also pollute the environment.


(1) Mechanical vibration and noise


If the pump shaft and motor shaft are not concentric or jacking, the bearing and coupling of the rotating shaft are damaged, the elastic pad is damaged and the assembly bolt is loose, which will produce noise. For the pump running at high speed or transmitting large energy, it is necessary to check regularly and record the amplitude, frequency and noise of each component. If the rotation frequency of the pump is the same as the natural frequency of the pressure valve, resonance will be caused. The rotation speed of the pump can be changed to eliminate the resonance.
