Due to the particularity of the use of diesel 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 machinery will generate a certain amount of heat during movement. At this time, the heat needs to be dissipated through cooling. Therefore, the generator set is generally cooled by fan water tank, so as to ensure that all mechanical parts of the generator set can be within a certain temperature control range.

但是，發(fā)電機(jī)組在使用過(guò)程中，經(jīng)常會(huì)產(chǎn)生水箱溫度過(guò)高，導(dǎo)致柴油機(jī)缸體過(guò)高，達(dá)到一定的溫度時(shí)會(huì)自動(dòng)停機(jī)（這是因?yàn)榘l(fā)電機(jī)組上裝有水高溫自動(dòng)保護(hù)功能），如果機(jī)組上沒(méi)有帶有自動(dòng)保護(hù)功能，那么會(huì)隨著發(fā)動(dòng)機(jī)的溫度越來(lái)越高，發(fā)動(dòng)機(jī)的缸體的溫度也越來(lái)越高，潤(rùn)滑油的潤(rùn)滑效果會(huì)越來(lái)越差，損傷發(fā)動(dòng)機(jī)缸體，那么，這個(gè)發(fā)電機(jī)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(xì)分析發(fā)電機(jī)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, resulting in the high temperature of the diesel engine cylinder block. When it reaches a certain temperature, it will shut down automatically (this is because the generator set is equipped with the automatic protection function of water high temperature). If the generator set is not equipped with the automatic protection function, the temperature of the engine cylinder block will be higher and higher as the engine temperature is higher and higher, and the lubrication effect of the lubricating oil will be worse and worse, If the engine block is damaged, what causes the high temperature of the water tank of the generator set? Below, Fengfa power will analyze the reasons for the high water temperature of the generator set in detail:

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(bǔ)燃期過(guò)長(zhǎng)，使冷卻水接觸氣缸壁的時(shí)間相對(duì)延長(zhǎng)，造成水溫過(guò)高，這個(gè)一般是根據(jù)柴油機(jī)的不同，它的噴油時(shí)間不同，正常的發(fā)動(dòng)機(jī)都不會(huì)存在這樣的問(wèn)題，除非機(jī)器收過(guò)損傷。

1、 The reason is that the injection time is too early or too late, which affects the combustion process, causes the supplementary combustion period to be too long, relatively prolongs the time for the cooling water to contact the cylinder wall, and causes the water temperature to be too high. This is generally based on the brand of diesel engine and its injection time. Such a problem will not exist in normal engines unless the machine is damaged.

二、是噴油量過(guò)大，造成混合氣過(guò)濃，緩燃期、補(bǔ)燃期相應(yīng)延長(zhǎng)，而使水溫過(guò)高。這個(gè)可能是由于突然加負(fù)載，或者突然加大油門(mén)造成

2、 The reason is that the fuel injection quantity is too large, resulting in too rich mixture, correspondingly prolonging the slow combustion period and supplementary combustion period, resulting in too high water temperature. This may be caused by sudden loading or sudden increase of 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 室壁上的柴油形成液態(tài)，不利于霧化險(xiǎn)為夷噴油壓力低，霧化質(zhì)量差。噴油器滴油使供油量大，引起水溫過(guò)高，嚴(yán)重時(shí)使噴油器燃損。

3、 The fuel injection pressure of the fuel 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 diesel injected on the combustion chamber wall forms a liquid, which is not conducive to atomization. The injection pressure is low and the atomization quality is poor. The fuel injector drips oil to make the fuel supply large, which causes the water temperature to be too high, and in serious cases, the fuel injector burns out.

四、是配氣相位失準(zhǔn)，使氣缸在壓縮終了時(shí)壓縮壓力降低；進(jìn)氣不充分，延長(zhǎng)了緩燃期和補(bǔ)燃期，引起水溫過(guò)高。進(jìn)氣系統(tǒng)堵塞也會(huì)使混合氣體過(guò)濃，發(fā)動(dòng)機(jī)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、 It is the misalignment of valve phase, which reduces the compression pressure of the cylinder at the end of compression; Insufficient air intake prolongs the slow combustion period and supplementary combustion period, resulting in too high water temperature. The blockage of the intake system will also make the mixture too thick, the engine emits black smoke, the power drops and the water temperature is too high. The wear of valve and valve seat ring, piston and cylinder liner reduce the compression force, cause poor combustion, make the water temperature too high and reduce the power performance.

五、是散熱器堵塞、水垢過(guò)多及風(fēng)扇膠帶松等均會(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 that the radiator is blocked, too much scale and the fan tape is loose, which will cause the water temperature to be too high. The low pressure and small flow of the water pump make the coolant circulation speed low, resulting in high water temperature. The water tank needs to be cleaned regularly and the coolant needs to be replaced

六、是發(fā)動(dòng)機(jī)內(nèi)部零部件之間摩擦阻力大，潤(rùn)滑條件不好，排氣管或消間器堵塞，發(fā)動(dòng)機(jī)負(fù)荷過(guò)大等也會(huì)造成水溫過(guò)高的現(xiàn)象。檢查使用的潤(rùn)滑油的油品及質(zhì)量。

6、 High friction resistance between internal parts of the engine, poor lubrication conditions, blocked exhaust pipe or eliminator, excessive engine load and so on will also cause the phenomenon of too high water temperature. Check the oil and quality of the lubricating oil used.
