空壓機節(jié)能改造的三種方式

對于空壓機的節(jié)能改造，山東空壓機認為，以下三種方式比較常見：

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

一.變頻調(diào)速方式

1、 Variable frequency speed regulation mode

采取變頻調(diào)速方式來降低空壓機電動機的軸功率輸出。改造之前，空壓機的壓力達到設(shè)定壓力時，即會自動卸荷；改造之后，空壓機并不卸荷，而是通過降低轉(zhuǎn)速來降低壓縮機時的產(chǎn)氣量，維持氣網(wǎng)需要的低壓力。這里有兩個地方可以節(jié)能：

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）減少壓縮機從卸荷狀態(tài)到加載狀態(tài)這一突變過程帶來的電能消耗。

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

（2）電機的運轉(zhuǎn)頻率降低至工頻以下，使電機軸的輸出功率減少。以上兩種方式都不同程度的降低了空壓機在運行過程中的能源消耗，但是空壓機在工作過程中產(chǎn)生如此大的熱

(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

能而讓它白白地散發(fā)到空氣中去，卻在很長的時間內(nèi)未得到用戶的普遍重視，這不能說不是一個極 大的遺憾。

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

對多臺空壓機采取集中控制方式。根據(jù)用氣情況自動控制空壓機的運行臺數(shù)，改造之前，空壓機開啟的臺數(shù)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）當(dāng)用氣減少到一定量時，空壓機是通過減少加載時間來減少產(chǎn)氣量。

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

（2）若用氣量進一步減少，性能好的空壓機則會自動停機。在（1）的情況下，空壓機即使是在卸載情況下也是要消耗電能的。改造后，便可停掉相應(yīng)臺數(shù)的空壓機，運行臺數(shù)減少了，無疑就節(jié)約了用電。

(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.空壓機熱 能回收是一項非常環(huán)保的節(jié)能方式

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

熱 能回收裝置工作原理：空壓機的高溫油經(jīng)過熱交換器把熱量傳遞到冷 卻水中，冷 卻水被加熱后流到保溫貯水桶中，這樣就可達到熱 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.

熱 能回收實現(xiàn)的條件：

The conditions of heat recovery are as follows

（1）空壓機的熱 能回收后，水能被加熱到多少度，有沒有較大的實用價值？

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

（2）同時油溫應(yīng)保持多少度，是否會影響空壓機的工況？

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

這些問題一直困擾著使用者，如果不能正確地解決這些問題，熱 能回收只能停留在紙上，成為空談。

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