形成四不像 策念头过早破坏的缘由

来历:http://pxcyw.cn/ 时候:2022-07-29

一些澳门四不像正版资料 司机反应,跟伴侣同时采办的统一款四不像 ,本身的车辆在利用一段时候后策念头就会呈现题目,但是伴侣的车辆策念头却没事,这究竟是怎样一回事呢?一路来领会一下吧。
Some small concrete mixer drivers reported that the same mixer they bought at the same time with their friends will have engine problems after using their vehicles for a period of time, but their friends' vehicle engines are all right. What's the matter? Let's have a look.
1. 四不像 的维修数据利用不妥
1. Improper application of maintenance data of mixer truck
在四不像 维修中不能迷信的挑选维修数据是形成机件初期破坏的主要缘由。比方气门与气门座打仗面的宽度,划定进气门为1-2.2mm,排气门为1.5-2.5mm。
The failure to scientifically select maintenance data in the maintenance of mixer truck is an important reason for the early damage of mechanical parts. For example, the width of the contact surface between the valve and the valve seat is specified as 1-2.2mm for the inlet valve and 1.5-2.5mm for the exhaust valve.
但在现实维修傍边,良多人以为宽一点比窄一点要好,习气选用上限或靠近上限值,由于刚修睦的车气门任务面宽度就已靠近利用极限了。再比方气门脚空隙,普通车辆划定为0.2-0.25mm,但在保护调剂中也会以为空隙大一点比小一点好,是以,超上限利用,现实上空隙过大,岂但下降策念头功率,还会呈现敲击声而初期破坏。
However, in actual maintenance, many people think that it is better to be a little wider than a little narrower, and they are used to choosing the upper limit or close to the upper limit, because the width of the valve working surface just repaired is close to the limit of use. Another example is the valve foot clearance, which is generally specified as 0.2-0.25mm for vehicles, but it is also considered that a larger clearance is better than a smaller clearance in maintenance and adjustment. Therefore, if it is used beyond the upper limit, in fact, the clearance is too large, which will not only reduce the engine power, but also cause knocking and early damage.
2. 气门的光磨
2. Smooth grinding of valve
在四不像 的维修中,若是气门呈现烧蚀、麻点及凸起时,均应停止光磨,普通是在光磨机上停止,功课时须要注重四个题目:一是保障气门头与杆部齐心,不然应先校直;二是光磨辆在能磨出完整的锥面的条件下是越小越好;三是尽能够进步外表光亮度;四是气门杆端部凸起应予以磨平。
In the maintenance of mixer truck, if the valve appears ablation, pitting and depression, it should be polished, usually on the grinder. Four problems should be paid attention to during operation: first, ensure that the valve head is concentric with the rod, otherwise it should be straightened first; Second, on the premise that the smooth grinding vehicle can grind a complete cone, the smaller the better; Third, try to improve the surface finish; Fourth, the depression at the end of the valve stem should be ground flat.

3. 气门导管的铰销
3. Hinge pin of valve guide
气门杆与气门导管共同空隙是决议气门导管利用寿命的关头,是以当改换新的气门导管时,铰销时应严酷把握好共同空隙,利用各四不像 车型划定空隙的上限,可有效耽误利用寿命。
The fit clearance between the valve stem and the valve guide is the key to determine the service life of the valve guide. Therefore, when replacing the new valve guide, the fit clearance should be strictly controlled when hinge pin is used. The lower limit of the clearance specified by each mixer model can effectively prolong the service life.
4. 气门的研磨
4. Grinding of valve
气门的研磨分为两种环境:一是气门与气门座只要轻细麻点,不须要光磨和铰销时的研磨;二是气门与气门座均颠末光磨和铰销后的研磨。前者先用足金钢砂研磨,将麻点研磨掉后,再用细金刚砂研磨,后涂上机油研磨,直至密封合适请求,宽度合适划定为止。后者只要密封性达不到请求时才停止研磨,但操纵时必然要注重,不要过度使劲,严禁将气门上下敲打,不然将呈现凹形砂痕,影响维修品质。
The grinding of valves can be divided into two cases: first, there are only slight pits between valves and valve seats, and there is no need for light grinding and grinding when pinning; Second, the valve and valve seat are polished and ground after hinge pin. The former is first ground with full gold steel sand, then the pitting is removed, then ground with fine emery, and then coated with engine oil until the sealing meets the requirements and the width meets the regulations. The latter can only be grinded when the sealing performance fails to meet the requirements, but it must be noted during operation that excessive force is not allowed, and it is strictly forbidden to knock the valve up and down, otherwise concave sand marks will appear, affecting the maintenance quality.
四不像 策念头出毛病不恐怖,恐怖的是维修不准确,那策念头的机能只会愈来愈差,以是存在的题目就要实时停止处置,更多内容就来网站http://pxcyw.cn征询吧。
It's not terrible that the mixer truck engine breaks down. The terrible thing is that the maintenance is not correct, and the performance of the engine will only get worse and worse. Therefore, the existing problems should be dealt with in time, and more content can be found on the website http://pxcyw.cn Consult.
