Pay attention to the engine loss when using a small mixer. After a long time of use, the engine of a small mixer will have some problems. But what are the causes of early engine damage of a small mixer, such as the consumption of the engine for daily maintenance. Let's get to know.

注册送200可提现的打鱼 在维修功课中凸起的题目是气门与气门座任务面加工品质达不到请求，形成任务面烧蚀、凸起而初期破坏；凸轮轴轴承在刮削中其共同空隙、打仗面积、各轴承齐心度达不到请求，加快磨损，呈现异响形成初期破坏；气门导管在改换新整机时，铰削品质若是达不到划定的请求，将会间接影响气门及气门座利用寿命。

The prominent problem of small concrete mixer in maintenance operation is that the machining quality of valve and valve seat working face cannot meet the requirements, resulting in ablation, depression and early damage of the working face; During the scraping of camshaft bearing, its fit clearance, contact area and concentricity of each bearing fail to meet the requirements, which accelerates the wear and causes early damage due to abnormal noise; When the valve guide is replaced with new parts, if the reaming quality fails to meet the specified requirements, the service life of the valve and valve seat will be directly affected.

注册送200可提现的打鱼 的凸轮轴轴承的刮削属于手工功课，保障品质有必然难度。为刮削便利，又凡是在气缸体外加工，是以应出格注重四个题目：一是要肯定好轴承刮削后内孔的直径（用公式表述为：内孔直径=轴颈直径实测值+共同空隙上限值+轴承与座孔过盈量实测值）；二是刮削中要尽可能注重坚持轴承内孔与外圆的同轴度；

The scraping of camshaft bearing of small concrete mixer belongs to manual operation, so it is difficult to ensure the quality. In order to facilitate scraping and generally process outside the cylinder, four problems should be paid special attention to: first, determine the diameter of the bearing inner hole after scraping (expressed by the formula: inner hole diameter=measured value of journal diameter+lower limit of fit clearance+measured value of interference between bearing and seat hole); Second, pay attention to keeping the coaxiality of bearing inner hole and outer circle as much as possible during scraping;

气门的研磨分为两种环境，一是气门与座只要轻细麻点，不须要光磨和铰削时的研磨；二是气门与座均已颠末光磨和铰削后的研磨。前者先用房钱刚砂研磨，将麻点研磨掉后，再用细金刚砂研磨，而后涂上机油研磨，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 the valve can be divided into two cases: one is that the valve and seat have only slight pitting, so the grinding of smooth grinding and reaming is not required; Second, the valve and seat have been polished and reamed. The former is first ground with emery, after the pitting is removed, it is then ground with fine emery, and then coated with oil for grinding until the sealing meets the requirements and the width meets the requirements. The latter shall be grinded only when the sealing performance fails to meet the requirements. However, care must be taken during operation to avoid excessive force. It is strictly prohibited to knock the valve up and down, or concave sand marks will appear, which will affect the maintenance quality.
