燃氣發(fā)電機組開(kāi)車(chē)前檢查確認無(wú)誤后才允許開(kāi)車(chē)
燃氣發(fā)電機組開(kāi)車(chē)前檢查確認無(wú)誤后才允許開(kāi)車(chē),這是使得燃氣發(fā)電機組正常運行的需要,也是對機組的維護保養措施,具體內容濟柴環(huán)能介紹!
The gas generator set can only be started after it is checked and confirmed to be correct before starting. This is the need to make the gas generator set operate normally, and it is also the maintenance measures for the unit. The specific content can be introduced by jichai Huaneng!
1、燃氣氣源管線(xiàn)與燃氣機進(jìn)氣接口處須安裝密封墊片并使得緊固可靠,應急手動(dòng)停車(chē)閥門(mén)功能應可靠。
1. The sealing gasket shall be installed at the interface between the gas source pipeline and the gas engine inlet to make the fastening reliable, and the function of the emergency manual shutdown valve shall be reliable.
2、燃氣管線(xiàn)的螺紋連接處須加纏密封膠帶,焊 接部位不得有氣孔。
2. The threaded connection of gas pipeline shall be wrapped with sealing tape, and the welding part shall be free of air hole.
3、檢查機房?jì)裙芫€(xiàn)是否漏氣,如有泄漏,須處理后再開(kāi)機。
3. Check whether there is air leakage in the pipeline in the machine room. If there is any leakage, deal with it before starting the machine.
燃氣部件的安裝
Installation of gas components
1、混合器法蘭及蝶門(mén)軸頸徑向間隙不得漏氣。
1. The radial clearance of mixer flange and butterfly valve journal shall not leak.
2、電磁閥、調壓閥的連接不得松動(dòng)漏氣。
2. The connection of solenoid valve and pressure regulating valve shall not be loose and air leakage.
3、各防爆裝置的易熔易爆膜片須按照技術(shù)設計要求安裝,不得隨意更換材料或加厚。
3. The fusible and explosive diaphragm of each explosion-proof device shall be installed according to the technical design requirements, and the material shall not be changed or thickened at will.
4、燃氣發(fā)電機組和控制屏與電纜接頭的連接須緊固可靠。
4. The connection between gas generator set, control panel and cable joint shall be firm and reliable.
傳感器與控制屏組合模擬檢測
Analog detection of sensor and control panel combination
1、油壓檢測:裝有壓力繼電器的原動(dòng)機,用壓力校驗儀檢測設定值,檢查控制屏是否分閘停機。裝有監控儀的原動(dòng)機,先自檢,然后拆下信號輸入線(xiàn)檢查控制屏是否分閘停機。
1. Oil pressure detection: for prime mover with pressure relay, use pressure calibrator to detect the set value and check whether the control panel is shut down. The prime mover equipped with monitor first checks itself, and then removes the signal input line to check whether the control panel is shut down or not.
2、油溫、水溫檢測:將模擬檢測好的傳感器與傳感器導線(xiàn)連接,把傳感器放在排氣管上加溫,檢測是否在設定值上分閘停機。
2. Oil temperature and water temperature detection: connect the analog sensor with the sensor wire, put the sensor on the exhaust pipe for heating, and detect whether the switch is turned off at the set value.
3、檢查燃氣發(fā)電機組氣源應急閥門(mén)、電磁閥是否可靠。
3. Check whether the emergency valve and solenoid valve of gas source are reliable.
4、減掉負載,合上短路器開(kāi)關(guān),把轉速開(kāi)關(guān)設置到額定轉速位置,然后調整2301A速度控 制 器的額定轉速電位器,緩慢順時(shí)針旋轉直至機組在設定值報 警分閘、超 速停機為止,然后將額定轉速電位器逆時(shí)針復位到原來(lái)的位置。
4, reduce load, close the switch of the short circuit, set the speed switch to the rated speed position, then adjust the 2301A speed controller's rated speed and potentiometer, rotate slowly clockwise until the unit set the alarm gate and speed down, and then reset the rated speed potentiometer counterclockwise to the original position.
1、開(kāi)機前,應清理機組(旋轉部件)上放置的雜物(如盤(pán)車(chē)杠、工具、螺釘等),以免開(kāi)車(chē)時(shí)工件飛出去傷人。
1. Before starting the machine, the sundries (such as turning bars, tools, screws, etc.) placed on the unit (rotating parts) should be cleaned to avoid the workpiece flying out and hurting people during the driving.
2、開(kāi)機前手動(dòng)盤(pán)車(chē)時(shí),注意先斷開(kāi)起動(dòng)電源,以免誤觸動(dòng)起動(dòng)按鈕,盤(pán)車(chē)杠飛出去傷人。
2. When turning manually before starting, pay attention to disconnect the starting power supply first, so as to avoid touching the starting button by mistake, and the turning bar will fly out and hurt people.
