發(fā)電機組為什么會(huì )出現水溫偏高?
由于瓦斯發(fā)電機組組使用的特殊性(它是由發(fā)動(dòng)機的高速轉動(dòng)產(chǎn)生的動(dòng)能通過(guò)發(fā)電機的勵磁轉化成電能而發(fā)電),機械在運動(dòng)時(shí)會(huì )產(chǎn)生一定的熱量,這時(shí)候熱量需要通過(guò)冷卻散發(fā)出去才行,所以發(fā)電機組一般都是通過(guò)風(fēng)扇水箱冷卻,從而保證發(fā)電機組的所有機械零部件都能在一定的溫控范圍之內。
Due to the particularity of gas generator set (it is generated by the kinetic energy generated by the high-speed rotation of the engine, which is converted into electric energy through the excitation of the generator), the machine will generate certain heat when it is in motion. At this time, the heat needs to be sent out through cooling, so the generator set is generally cooled through the fan water tank, so as to ensure all mechanical zero of the generator set All parts can be controlled within a certain temperature range.
但是,發(fā)電機組在使用過(guò)程中,經(jīng)常會(huì )產(chǎn)生水箱溫度過(guò)高,導致瓦斯發(fā)電機組缸體過(guò)高,達到一定的溫度時(shí)會(huì )自動(dòng)停機(這是因為發(fā)電機組上裝有水高溫自動(dòng)保護功能),如果機組上沒(méi)有帶有自動(dòng)保護功能,那么會(huì )隨著(zhù)發(fā)動(dòng)機的溫度越來(lái)越高,發(fā)動(dòng)機的缸體的溫度也越來(lái)越高,潤滑油的潤滑效果會(huì )越來(lái)越差,損傷發(fā)動(dòng)機缸體,那么,這個(gè)發(fā)電機組的水箱溫度高是由什么引起的呢,下面,鋒發(fā)動(dòng)力為您詳細分析發(fā)電機組水溫過(guò)高的原因:
However, during the use of the generator set, the temperature of the water tank is often too high, which leads to the high temperature of the cylinder block of the gas generator set. When it reaches a certain temperature, it will stop automatically (this is because the generator set is equipped with the automatic protection function of water high temperature). If the generator set does not have the automatic protection function, the temperature of the cylinder block of the engine will increase with the increasing temperature of the engine The lubricating effect of the lubricating oil will be worse and worse, and the engine block will be damaged. Then, what is the reason for the high temperature of the water tank of the generator set
一、是噴油時(shí)間過(guò)早或過(guò)遲屬,影響燃燒過(guò)程,引起補燃期過(guò)長(cháng),使冷卻水接觸氣缸壁的時(shí)間相對延長(cháng),造成水溫過(guò)高,這個(gè)一般是根據瓦斯發(fā)電機組的品牌不同,它的噴油時(shí)間不同,正常的發(fā)動(dòng)機都不會(huì )存在這樣的問(wèn)題,除非機器收過(guò)損傷。
1、 If the injection time is too early or too late, it will affect the combustion process, cause the supplementary combustion period to be too long, make the cooling water contact the cylinder wall for a relatively long time, and cause the water temperature to be too high. Generally, according to the brand of gas generator set, the injection time is different, and the normal engine will not have such a problem, unless the machine has been damaged.
二、是噴油量過(guò)大,造成混合氣過(guò)濃,緩燃期、補燃期相應延長(cháng),而使水溫過(guò)高。這個(gè)可能是由于突然加負載,或者突然加大油門(mén)造成
2、 The reason is that the injection quantity is too large, the mixture is too rich, the slow combustion period and supplementary combustion period are prolonged correspondingly, and the water temperature is too high. This may be due to a sudden load, or a sudden increase in the throttle
三、是噴油器噴油壓力過(guò)高或過(guò)低,使燃油的噴射行程和霧化質(zhì)量受到影響。噴油壓力過(guò)高,噴在燃燒 室壁上的瓦斯發(fā)電機組形成液態(tài),不利于霧化險為夷噴油壓力低,霧化質(zhì)量差。噴油器滴油使供油量增大,引起水溫過(guò)高,嚴重時(shí)使噴油器燃損。
3、 The reason is that the injection pressure of the injector is too high or too low, which affects the injection stroke and atomization quality of the fuel. If the injection pressure is too high, the gas generator unit sprayed on the combustion chamber wall will form a liquid state, which is not conducive to the risk of atomization. The dropping oil of the fuel injector increases the fuel supply quantity, causes the water temperature to be too high, and causes the fuel injector to burn in serious cases.
四、是配氣相位失準,使氣缸在壓縮終了時(shí)壓縮壓力降低;進(jìn)氣不充分,排氣徹底,延長(cháng)了緩燃期和補燃期,引起水溫過(guò)高。進(jìn)氣系統堵塞也會(huì )使混合氣體過(guò)濃,發(fā)動(dòng)機冒黑煙,動(dòng)力下降,水溫過(guò)高。氣門(mén)和氣門(mén)座圈磨損,活塞和缸套磨損均使壓縮力降低,引起燃燒不良也使水溫過(guò)高,動(dòng)力性能下降。
4、 The reason is that the valve timing is out of alignment, so that the compression pressure of the cylinder is reduced at the end of compression; the intake air is not sufficient, and the exhaust gas is complete, which prolongs the slow combustion period and supplementary combustion period, and causes the water temperature to be too high. If the intake system is blocked, the mixture will be too rich, the engine will emit black smoke, the power will drop, and the water temperature will be too high. The wear of valve and valve seat ring, piston and cylinder liner can reduce the compression force, cause poor combustion, and make the water temperature too high and the power performance decline.
五、是散熱器堵塞、水垢過(guò)多及風(fēng)扇膠帶松弛等均會(huì )造成水溫過(guò)高。水泵壓力低,流量小,使冷卻液循環(huán)速度慳,從而造成水溫過(guò)高。需要定期清洗水箱,更換冷卻液
5、 It is blocked radiator, too much scale and loose fan tape that can cause high water temperature. The low pressure and low flow of the water pump make the circulation speed of the coolant low, resulting in the high water temperature. The water tank needs to be cleaned regularly and the coolant needs to be changed
六、是發(fā)動(dòng)機內部零部件之間摩擦阻力大,潤滑條件不好,排氣管或消間器堵塞,發(fā)動(dòng)機負荷過(guò)大等也會(huì )造成水溫過(guò)高的現象。檢查使用的潤滑油的油品及質(zhì)量。
6、 It is the high friction resistance between the internal parts of the engine, bad lubrication conditions, exhaust pipe or eliminator blockage, engine load is too large and so on will also cause the phenomenon of high water temperature. Check the quality of the lubricating oil used.
