空压机改造的三种方式

对于空压机的改造，山东空压机认为，以下三种方式比较常见：

For the energy-saving transformation of air compressor, Shandong air compressor believes that the following three ways are common:

一.变频调速方式

1、 Variable frequency speed regulation mode

采取变频调速方式来降低空压机电动机的轴功率输出。改造之前，空压机的压力达到设定压力时，即会自动卸荷；改造之后，空压机并不卸荷，而是通过降低转速来降低压缩机时的产气量，维持气网需要的低压力。这里有两个地方可以：

Frequency conversion speed regulation is adopted to reduce the shaft power output of air compressor motor. Before the transformation, when the pressure of the air compressor reaches the set pressure, it will unload automatically; After the transformation, the air compressor does not unload, but by reducing the speed of the compressor to reduce the gas production, maintain the low pressure of the gas network. There are two places to save energy:

（1）减少压缩机从卸荷状态到加载状态这一突变过程带来的电能消耗。

(1) Reduce the power consumption caused by the sudden change of compressor from unloading state to loading state.

（2）电机的运转频率降低工频以下，使电机轴的输出功率减少。以上两种方式都不同程度的降低了空压机在运行过程中的能源消耗，但是空压机在工作过程中产生如此大的热

(2) The operating frequency of the motor is reduced to below the power frequency, so that the output power of the motor shaft is reduced. The above two ways reduce the energy consumption of the air compressor in different degrees, but the air compressor produces so much heat in the working process

能而让它白白地散发到空气中去，却在很长的时间内未得到用户的普遍重视，这不能说不是一个极 大的遗憾。

It's not a great pity that users have not paid attention to it for a long time.

二.集中控制方式

2、 Centralized control mode

对多台空压机采取集中控制方式。根据用气情况自动控制空压机的运行台数，改造之前，空压机开启的台数是固定的。

Centralized control mode is adopted for multiple air compressors. The number of air compressors can be automatically controlled according to the gas consumption. Before the transformation, the number of air compressors opened is fixed.

（1）当用气减少到一定量时，空压机是通过减少加载时间来减少产气量。

(1) When the gas consumption is reduced to a certain amount, the air compressor reduces the gas production by reducing the loading time.

（2）若用气量进一步减少，性能好的空压机则会自动停机。在（1）的情况下，空压机即使是在卸载情况下也是要消耗电能的。改造后，便可停掉相应台数的空压机，运行台数减少了，无疑就节约了用电。

(2) If the air consumption is further reduced, the air compressor with good performance will stop automatically. In the case of (1), the air compressor will consume electric energy even when it is unloaded. After the transformation, the corresponding number of air compressors can be stopped, and the number of operating units is reduced, which undoubtedly saves electricity.

三.空压机热 能回收是一项非常的方式

3、 Air compressor heat recovery is a very environmentally friendly way of energy saving

热 能回收装置工作原理：空压机的高温油经过热交换器把热量传递到冷 却水中，冷 却水被加热后流到保温贮水桶中，这样就可达到热 能回收的目的。

Working principle of heat energy recovery device: the high temperature oil of air compressor transfers heat to cooling water through superheater, and the cooling water flows into heat preservation water tank after being heated, so as to achieve the purpose of heat energy recovery.

热 能回收实现的条件：

The conditions of heat recovery are as follows

（1）空压机的热 能回收后，水能被加热到多少度，有没有较大的实用价值？

(1) Air compressor heat recovery, water can be heated to how many degrees, there is no greater practical value?

（2）同时油温应保持多少度，是否会影响空压机的工况？

(2) At the same time, how much oil temperature should be maintained, whether it will affect the working condition of the air compressor?

这些问题一直困扰着使用者，如果不能正确地解决这些问题，热 能回收只能停留在纸上，成为空谈。

If these problems can not be solved correctly, the heat recovery can only stay on the paper and become empty talk.
