經(jīng)常有人咨詢到養(yǎng)殖場內(nèi)應(yīng)該用什么樣的發(fā)電機(jī)組，多大千瓦數(shù)的發(fā)電機(jī)組？可以根據(jù)自身的情況選擇沼氣發(fā)電機(jī)組，或者選擇普通柴油發(fā)電機(jī)組。

People often ask what kind of generator set should be used in the farm, and how many kilowatts of generator set should be used? You can choose biogas generator set or ordinary diesel generator set according to your own situation.

一般養(yǎng)殖場內(nèi)的設(shè)備，分兩種，一種是水產(chǎn)養(yǎng)殖中供氧一類的設(shè)備，那種一般需要長時間運行的，另外一種就是想粉碎機(jī)等，每天用1-2個小時，那種非常用的機(jī)器，比備用的使用時間長。

Generally, there are two kinds of equipment in the farm. One is the equipment for oxygen supply in aquaculture, which generally needs to be operated for a long time. The other is the shredder, which is used for 1-2 hours a day. The machine that is very used takes longer than the standby one.

那么如何選擇準(zhǔn)確的發(fā)電機(jī)組，達(dá)到高性價比呢？

So how to select an accurate generator set to achieve high cost performance?

很多機(jī)器的啟動電流都要大，一般是2-3倍，這就要求配比的發(fā)電機(jī)組時，也要2倍以上甚至是3倍（水泵），比如一個12kw的粉碎機(jī)，那么單獨配發(fā)電機(jī)組時就要2倍-2.5倍，那么就應(yīng)該選擇30kw的發(fā)電機(jī)組比較好！

The starting current of many machines should be large, usually 2-3 times, which requires that the matching generator set should be more than 2 times or even 3 times (water pump). For example, if a 12KW crusher is equipped with a generator set alone, it should be 2-2.5 times, so it is better to choose a 30kW generator set!

當(dāng)然這里的配比，不是所有機(jī)器負(fù)載的總和的2-3倍，這么說吧，主要考慮負(fù)載前三位機(jī)器的負(fù)載。當(dāng)然這種情況指的是有人操作，可以一臺一臺啟動機(jī)器的情況下。如果想要同時啟動，則要2倍以上。

Of course, the ratio here is not 2-3 times the total load of all machines. Let's put it this way, we mainly consider the load of the top three machines. Of course, this kind of situation refers to the situation that someone can start the machine one by one. If you want to start at the same time, it needs more than 2 times.

當(dāng)然作為銷售發(fā)電機(jī)組的廠家，結(jié)合我的銷售發(fā)電機(jī)組的經(jīng)驗，我并不推薦如此配比，因為性價比不高。

Of course, as a manufacturer selling generator sets, combined with my experience in selling generator sets, I do not recommend such a ratio, because the cost performance is not high.

我推薦的配比是根據(jù)具體情況，分開啟動，然后計算所需發(fā)電機(jī)組的kw數(shù)。

The ratio I recommend is to start up separately according to specific conditions, and then calculate the kW of the required generator set.

例如：養(yǎng)殖場內(nèi)設(shè)備總負(fù)載53kw,其中大的幾個負(fù)載機(jī)器分別為24kw,12kw,7.5kw.剩余其他。

For example, the total load of equipment in the farm is 53kw, of which the large load machines are 24kw, 12KW and 7.5kW respectively Others remaining.

如果按照兩倍以上的配比的話，同時啟動就需要120kw的發(fā)電機(jī)組才能啟動正常運行。

If the ratio is more than twice, 120kw generator set is required to start up at the same time for normal operation.

但實際上，并不需要同時啟動，像這個機(jī)器的話，可以單個啟動，先啟動24kw的機(jī)器，再啟動12kw的，啟動7.5kw的機(jī)器，大功率機(jī)器啟動后，將剩余的全部啟動，這樣的話，機(jī)組配比功率為75kw,就足夠了。

However, in fact, it is not necessary to start the machine at the same time. For this machine, it can be started individually. First, start the 24kw machine, then the 12KW machine, and then start the 7.5kW machine. After the high-power machine is started, all the rest will be started. In this case, the matching power of the unit is 75kW, which is enough.

可能有些人不會算，這個簡單，

Some people may not be able to calculate it. This is simple,

75kw的發(fā)電機(jī)組，啟動一臺，需2-3倍電流，就是48kw，滿足，啟動。

For a 75kW generator set, it needs 2-3 times the current to start, that is, 48kW. If it is satisfied, start it.

正常運行后恢復(fù)正常，還剩51kw，然后再啟動12kw的，需24kw,滿足，啟動，

After normal operation, it returns to normal, 51kw remains, and then 12KW is started, 24kw is required. If it meets the requirements, start it,

正常運行后恢復(fù)正常，還剩39kw,后再啟動7.5kw的， 需15kw,滿足，啟動，

After normal operation, it returns to normal, 39KW remains, and 15kw is required for 7.5kW startup. If it meets the requirements, it can be started,

正常運行后恢復(fù)正常，還剩31.5kw,整個全部負(fù)載剩余9.5kw,也是可以啟動的。

After normal operation, it returns to normal, 31.5kw remains, and 9.5Kw remains for the whole load, which can also be started.

所以上述所有電器全部啟動完畢，當(dāng)然了，上述計算我是按照2倍電流計算的，實際情況可能按照2倍，2.5倍，或三倍的來計算。根據(jù)實際情況，來確定！

Therefore, all the above electrical appliances have been started. Of course, the above calculation is based on 2 times the current, and the actual situation may be based on 2 times, 2.5 times, or 3 times. Determine according to the actual situation!

這樣的好處是節(jié)約了成本，雖然聽起來負(fù)載了，但實際上，只是總開關(guān)位置控制而已！

The advantage of this is that the cost is saved. Although it sounds like a load, in fact, it is only the position control of the main switch!
