對于自動變速箱的電磁閥有時候我們顯得束手無策，因?yàn)槲覀儧]有鑒定它好壞的標(biāo)準(zhǔn)，有時候因?yàn)樗鸬墓收蠒r有時無，經(jīng)常使我們感到困惑。下面
濟(jì)南自動變速箱維修人員為您解析：
Sometimes we feel helpless about the solenoid valve of an automatic transmission because we do not have a standard for evaluating its quality. Sometimes, the faults caused by it are sporadic and often confuse us. Below, Jinan automatic transmission maintenance personnel will analyze for you:
小編認(rèn)為對于電磁閥我們應(yīng)該把它看作是噴油嘴的另一種工作方式，因?yàn)閲娪妥旌碗姶砰y所發(fā)生的故障不外乎堵塞和滴漏。
The editor believes that for solenoid valves, we should consider them as another way of working for fuel injectors, because the faults that occur with the fuel injectors and solenoid valves are nothing more than blockage and dripping.
但是噴油嘴造成的結(jié)果我們可以通過分析發(fā)動機(jī)的短期和長期燃油調(diào)整值來加以確定。如果長期燃油調(diào)整超過百分之＋10，就表示油泵油壓過低或噴油嘴堵塞。
However, the results caused by the fuel injectors can be determined by analyzing the short-term and long-term fuel adjustment values of the engine. If the long-term fuel adjustment exceeds+10%, it indicates that the oil pump pressure is too low or the fuel injection nozzle is blocked.
如果如果怠速時短期燃油調(diào)整超過百分之－10，則表示油泵油壓過高或個別噴油嘴泄漏。噴油嘴對應(yīng)發(fā)動機(jī)電腦的相應(yīng)控制精度應(yīng)該小于0.01毫秒。
If the short-term fuel adjustment during idle exceeds -10%, it indicates that the oil pump pressure is too high or individual fuel injectors are leaking. The corresponding control accuracy of the engine computer corresponding to the fuel injector should be less than 0.01 milliseconds.
雖然我們不能像對待噴油嘴那樣的判斷出故障的原因，我也不知道變速箱電腦相應(yīng)電磁閥的控制精度是否比噴油嘴高（應(yīng)該是電磁閥要比噴油嘴的控制精度低，因?yàn)閾Q檔過程是以秒為單位計算的，占空比電磁閥的控制頻率一般是60HZ），但是我們開的是一樣的，使用超聲波清洗機(jī)清洗40分鐘。因?yàn)樵斐晒收系脑蚴窍嗤模?/div>
Although we can't judge the cause of the fault as we do with the fuel injection nozzle, I don't know whether the control accuracy of the corresponding solenoid valve of the transmission computer is higher than that of the fuel injection nozzle (it should be that the control accuracy of the solenoid valve is lower than that of the fuel injection nozzle, because the shift process is calculated in seconds, and the control frequency of the duty cycle solenoid valve is generally 60HZ), but we open the same, use the Ultrasonic cleaning to clean for 40 minutes. Because the causes of the malfunction are the same:
都是被磨損并污染造成的，所以相同。01N電磁閥因?yàn)榻Y(jié)構(gòu)所至，不光存在污染，有可能還有球閥的磨損，所以清洗之后要用其它方法做進(jìn)一步鑒定。01V的電磁閥則是存在于電磁閥內(nèi)部的磨損雜質(zhì)很難去除，所以我們使用汽油作為清洗劑，并且清洗40分鐘以上。
They are all caused by wear and pollution, so they are the same. Due to its structure, the 01N solenoid valve is not only contaminated, but may also have wear on the ball valve. Therefore, after cleaning, other methods should be used for further identification. The 01V solenoid valve is difficult to remove wear impurities that exist inside the solenoid valve, so we use gasoline as a cleaning agent and clean it for more than 40 minutes.
不管什么型號的變速箱須把電磁閥清洗的干凈，使用手工方法是很難做到的。值得注意的是要使用頻率40KHZ左右的超聲波清洗，使用頻率20KHZ或更低的超聲波容易造成電磁閥內(nèi)部的損壞。還有什么事項就來我們網(wǎng)站

No matter what model of gearbox, it is difficult to clean the solenoid valve manually. It is worth noting that ultrasonic cleaning with a frequency of around 40KHZ should be used, as using ultrasonic waves with a frequency of 20KHZ or lower can easily cause damage to the interior of the solenoid valve.
