大家都知道，空压机的电机是决定空压机工作效率的一个重要因素。以前几天文章中提到的德瑞亚永磁变频机为例，德瑞亚因为搭配了一颗永磁电机，与工频机相比，机器运行效率会更高。同样由于电机功率的浮动，机器的排气量也会出现变化。有的时候，排气量会出现“不够用”的状况，今天小编为大家浅谈一下机器排气量出现下降的几个原因。

1 空压机排气压力没有达到额定效果；以通俗易懂的语言来解释，即机器未能满足工厂最低用气需求。如何来检查是否满足了最低用气？欧能优售后部的严工在为用户的储气罐做类似检查的时候，曾使用这样一种方法：将储气罐后的阀门封死，如果机器出现压力迅速上升，再解开阀门，压力又回去，基本可证明该型号不能满足最低用气需求。

解决办法：增加空压机数量，具体数量和型号视情况而定；

2 由机器方面导致的故障（机器排气量下降），主要是几个原因造成的：（1）保养不充分，适当加油、更换空滤等配件；（2）机器传送皮带松弛，导致排气量缩减； （3）不是所有的进气阀都能打开；（4）机子电机发生电路短路或由于老化造成磨损。（5）处于水蒸气较多的潮湿环境中，机器处理多余水分的能力不够，排气量在这种环境中出现下降。

造成机器排气量变小的原因各式各样，在日常的使用过程中，以上这些是我们最常碰到的几种情况。

As we all know, the motor of air compressor is an important factor to determine the working efficiency of air compressor. As an example, the Drea permanent magnet frequency converter mentioned in previous astronomical chapters, because Drea is equipped with a permanent magnet motor, compared with the power frequency machine, the machine runs more efficiently. Similarly, due to the fluctuation of motor power, the exhaust volume of the machine will also change. Sometimes, the exhaust volume will appear "insufficient" situation, today for everyone to talk about the machine exhaust volume decline in several reasons.



1. The exhaust pressure of the air compressor does not reach the rated effect; to explain in plain language, that is, the machine fails to meet the minimum gas demand of the factory. How to check whether the minimum gas consumption is met? When Euro's rigorous worker at the back of the sales department made similar checks for users'gas storage tanks, he used such a method: seal the valve behind the gas storage tank, if the pressure of the machine rises rapidly, then unlock the valve, and the pressure goes back, it can basically prove that the model can not meet the minimum gas demand.



Solution: Increase the number of air compressors, the specific number and type depend on the situation;



Faults caused by machine (decrease of exhaust volume) are mainly caused by several reasons: (1) insufficient maintenance, proper refueling, replacement of air filter and other accessories; (2) looseness of conveyor belt of machine, resulting in reduction of exhaust volume; (3) not all intake valves can be opened; (4) short circuit of motor circuit or wear due to aging. (5) In the humid environment with more water vapor, the ability of the machine to deal with excess water is not enough, and the exhaust volume decreases in this environment.



There are various reasons for the reduction of exhaust volume. In the daily use process, these are the most common situations we encounter.
