对于高压离心风机的防护需要注意些什么呢？这就是本期离心风机厂家要为大家讲解的相关问题：1) 对于压力，为了防止马达负载过重，比较常使用的是释压阀，它是一个卸荷阀，如果当高压离心风机的使用压力超过释压阀设定的压力之后，释压阀就会自动打开，把其中多余的压力释放掉，从而防止长期极限压力导致轴功率加大损坏。 没有啦

What should we pay attention to for the protection of high-pressure centrifugal fan? This is the related problem that the manufacturer of centrifugal fan will explain for you in this period: 1) For pressure, in order to prevent motor from overloading, the pressure relief valve is commonly used. It is a unloading valve. If the pressure of high-pressure centrifugal fan exceeds the pressure set by the pressure relief valve, the pressure relief valve will automatically open and release the excess pressure, so as to prevent the long-term limit. Pressure leads to increased shaft power damage.

(2) 对于粉尘，由于高压离心风机内部的机构比较紧密，其风机叶轮和机壳间隙很小，要过滤杂物和粉尘常使用的是过滤器。因为不同的使用现场，使用的过滤滤芯的过滤精度往往不同，维护方法和使用寿命也不相同，所以在与风机厂家订货的时候就需要问清楚。

(2) For dust, because the internal mechanism of the high-pressure centrifugal fan is relatively close, the clearance between the impeller and the casing of the fan is very small. The filter is often used to filter impurities and dust. Because the filtering accuracy of the filter element used is often different and the maintenance method and service life are different in different use sites, it is necessary to ask clearly when ordering with the fan manufacturer.

(3) 高压离心风机在一些特殊的场合使用，还需要对风机本身进行特殊的保护：比如说在密闭环境中使用时，要注意环境的通风散热情况；尤其是当环境温度比较高的时候，更要注意通风散热，或者选择允许进风温度较高的风机 。

(3) When high-pressure centrifugal fans are used in some special occasions, special protection should also be given to the fans themselves: for example, when they are used in closed-loop environment, attention should be paid to the ventilation and heat dissipation of the environment; especially when the ambient temperature is relatively high, attention should be paid to ventilation and heat dissipation, or the fans with higher intake temperature should be selected.
