放置了半年的焦化發(fā)電機(jī)組需要做哪些檢測(cè)呢？實(shí)際上不算很難，一般的要做以下幾點(diǎn)檢查：

What tests should be done for the coking generator set that has been placed for half a year? In fact, it is not very difficult. Generally, the following checks are required:

1、檢查機(jī)組的啟動(dòng)成功率

1. Check the startup success rate of the unit

試驗(yàn)方法：試驗(yàn)應(yīng)在符合產(chǎn)品技術(shù)條件規(guī)定的準(zhǔn)備啟動(dòng)狀態(tài)下，每給一個(gè)啟動(dòng)指令，啟動(dòng)成功后突加功率為1.0的50% 的額定負(fù)載運(yùn)行5min，再停機(jī)。試驗(yàn)100次。啟動(dòng)成功率應(yīng)大于99%。否則，則認(rèn)為此項(xiàng)不合格。

Test method: the test shall be carried out in the ready to start state in accordance with the technical conditions of the product. After each start command is given, the test shall be conducted with 50% of the rated load of 1.0 for 5min and then shut down. 100 tests. The startup success rate shall be greater than 99%. Otherwise, it is considered as unqualified.

2、檢查機(jī)組平均故障間隔期

2. Check the mean time between failures of the unit

檢查方法：機(jī)組帶cosФ=0.8的額定負(fù)載，連續(xù)或累計(jì)運(yùn)行1000h以上，焦化機(jī)、發(fā)電機(jī)均不應(yīng)出現(xiàn)故障，控制電路的 元件不應(yīng)出現(xiàn)二次以上故障，否則，則認(rèn)為此項(xiàng)不合格。此項(xiàng)指標(biāo)允許在實(shí)際運(yùn)行中進(jìn)行考核。

Inspection method: unit with cos Ф= 0.8 rated load, continuous or cumulative operation for more than 1000h, the coking machine and generator shall not have fault, and the elements of the control circuit shall not have more than two faults, otherwise, this item is considered unqualified. This indicator can be evaluated in actual operation.

3、檢查機(jī)組帶可控硅負(fù)載的運(yùn)行情況

3. Check the operation of the unit with thyristor load

試驗(yàn)方法：機(jī)組帶cosФ≥0.5的三相可控硅整流器負(fù)載，在機(jī)組額定容量的10%～50%范圍內(nèi)任一點(diǎn)上均應(yīng)能穩(wěn)定工作 。如果產(chǎn)生低頻振蕩，應(yīng)實(shí)行調(diào)整，使之能穩(wěn)定工作，否則認(rèn)為此項(xiàng)不合格。

Test method: unit with cos Ф The load of three-phase thyristor rectifier ≥ 0.5 shall be able to work stably at any point within the range of 10% ~ 50% of the rated capacity of the unit. If low-frequency oscillation occurs, it shall be adjusted to make it work stably. Otherwise, it is considered unqualified.

4、檢查自動(dòng)化機(jī)組的聯(lián)動(dòng)試

4. Check the linkage test of the automatic unit

檢查方法：兩臺(tái)機(jī)組應(yīng)互為主備用，任選一臺(tái)作主用，人為切斷市電，主用機(jī)組自動(dòng)啟動(dòng)成功后供電。制造一個(gè)故障 ，使主用機(jī)組自動(dòng)停機(jī)備用機(jī)組則應(yīng)自動(dòng)成功后供電。使市電恢復(fù)后，備用機(jī)組應(yīng)級(jí)自動(dòng)停機(jī)。如不合格，找出原因，排 除故障。兩臺(tái)機(jī)組分別為主用，復(fù)試三次，如仍有一次不合格，則認(rèn)為此項(xiàng)不合格。

Inspection method: two units shall be used as main and standby for each other, and one unit shall be selected as the main one. The mains power shall be cut off manually, and the power supply shall be supplied after the main unit is automatically started successfully. If a fault is caused, the main unit will automatically shut down, and the standby unit will automatically supply power after success. After the mains power is restored, the standby unit shall stop automatically. If unqualified, find out the reason and eliminate the fault. The two units are mainly used and retested for three times. If one is still unqualified, it is considered as unqualified.

5、檢查自動(dòng)化焦化發(fā)電機(jī)組自動(dòng)啟動(dòng)功能

5. Check the automatic startup function of the automatic coking generator set

試驗(yàn)方法：接通啟動(dòng)電源，將機(jī)組工作方式選擇開關(guān)搬向自動(dòng)，送入啟動(dòng)指令，并且人為使機(jī)組啟動(dòng)不成功，機(jī)組應(yīng) 自動(dòng)啟動(dòng)三次。

Test method: connect the startup power supply, move the unit working mode selection switch to automatic, and send the startup command. If the unit fails to be started manually, the unit shall be started automatically for three times.

試驗(yàn)三次，只要有一次不合格，復(fù)試次數(shù)加倍，若仍有一次不合格，則認(rèn)為此項(xiàng)不合格。

If one of the three tests is unqualified, the number of retests shall be doubled. If there is still one unqualified, it is considered to be unqualified.

6、檢查自動(dòng)化機(jī)組的自動(dòng)補(bǔ)給裝置

6. Check the automatic supply device of the automatic unit

試驗(yàn)方法：在控制電路電路完全聯(lián)結(jié)完畢后，將工作方式選擇開關(guān)搬向自動(dòng)人為放水放油至低液位，應(yīng)能自動(dòng)補(bǔ)給， 當(dāng)液面上升到高液位時(shí)補(bǔ)給應(yīng)能自動(dòng)停止。

Test method: after the control circuit is fully connected, move the working mode selection switch to automatic manual water and oil drainage to the low level, which shall be able to automatically replenish. When the liquid level rises to the high level, the replenishment shall be able to automatically stop.

試驗(yàn)三次，只要有一次不合格，復(fù)試次數(shù)加倍，若仍有一次不合格，則認(rèn)為此項(xiàng)不合格。

If one of the three tests is unqualified, the number of retests shall be doubled. If there is still one unqualified, it is considered to be unqualified.

此外也要檢查自動(dòng)化機(jī)組的保護(hù)性、檢查自動(dòng)化機(jī)組的冷卻水、機(jī)油加熱等事項(xiàng)，更多檢查項(xiàng)目合格才能進(jìn)行下一步 使用，詳情就來我們網(wǎng)站http://www.cxxrdz.com聯(lián)系了解吧。

In addition, it is also necessary to check the protection of the automatic unit, check the cooling water and oil heating of the automatic unit. More inspection items can be used in the next step only if they are qualified. Please visit our website for details http://www.huannengpower. Contact me to understand.
