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.
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.
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;
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.
The reason for the early damage of the engine of small concrete mixer is the above content. If you have any questions about this, you can come to our website at any time http://zhaoyanfilter.com Get to know!
