1. Improper use of maintenance data of small mixer在小型搅拌器的维护中，维护数据不能科学选择是一个重要原因。例如，阀门与阀座的接触面宽度规定为进口阀门1-2.2mm，排气阀门1.5-2.5mm。然而，在实际的维修中，很多人认为宽比窄更好，他们习惯选择上限值或接近上限值，因为刚维修的阀门工作面的宽度接近使用极限。另一个例子是阀门间隙,一般车辆监管是0.2 - -0.25毫米,但在维护调整也认为间隙有点超过小一点更好,因此,使用超过上限,实际上间隙太大,不仅降低发动机功率,还会出现敲门声音和早期损坏。

　　In the maintenance of small stirrers, it is an important reason that the maintenance data can not be selected scientifically. For example, the contact surface width between valve and valve seat is specified as 1-2.2mm for inlet valve and 1.5-2.5mm for exhaust valve. However, in the actual maintenance, many people think that width is better than narrow, they are used to choose the upper limit value or close to the upper limit value, because the width of the working face of the valve just repaired is close to the service limit. Another example is valve clearance. The general vehicle supervision is 0.2-0.25 mm. However, in maintenance adjustment, it is also considered that the clearance is a little bit better than the smaller one. Therefore, if the use exceeds the upper limit, the clearance is actually too large, which not only reduces the engine power, but also causes knocking sound and early damage.

　　2.小型混合器阀门的光滑磨削

　　2. Smooth grinding of small mixer valve

　　在小型搅拌器的维护中，如果阀门出现烧蚀、麻点、麻点，应进行光滑磨削，一般在光滑磨床上进行。在操作中应注意四个问题。其次，轻磨车在磨削完全锥体的前提下是越小越好;三是尽量提高表面光洁度;第四，阀杆端部凹陷处应打磨。

　　In the maintenance of small agitator, if the valve has ablation, pockmarks and pockmarks, smooth grinding shall be carried out, generally on the smooth grinder. Four problems should be paid attention to in operation. Secondly, on the premise of grinding the complete cone, the smaller the smaller the better; thirdly, improve the surface finish as much as possible; fourthly, the end depression of the valve rod should be polished.

　　3.小型混合器阀道铰链销

　　3. Small mixer valve channel hinge pin

　　阀杆与导尿管的配合间隙是决定导尿管使用寿命的关键。因此，更换新的阀门导管时，铰链销应严格控制配合间隙，每一种类型的混合器规定的间隙下限能有效延长使用寿命。

　　The fit clearance between the valve rod and the catheter is the key to determine the service life of the catheter. Therefore, when replacing the new valve guide, the hinge pin shall strictly control the fit clearance, and the lower limit of clearance specified for each type of mixer can effectively extend the service life.

　　4.研磨小型混合器的阀门

　　4. Grind the valve of small mixer

　　小型搅拌机内的阀门研磨有两种:一是阀门与阀座仅有轻微的点蚀点，不需要研磨和铰销;二是阀门与阀座研磨光滑，铰销研磨后。前者先用纯金钢砂磨碎，麻尖磨掉后，再用细砂磨碎，涂油磨碎，直到封口符合要求，宽度到目前为止符合规定。后者只能在研磨时松紧达不到要求，但一定要注意操作，不要用力过猛，严禁上下撞击阀门，否则会出现凹砂痕，影响维修质量。

　　There are two kinds of valve lapping in the small mixer: one is that there is only slight pitting between the valve and the valve seat without lapping and hinge pin; the other is that the valve and the valve seat are lapping smoothly after hinge pin lapping. The former is first ground with pure steel sand, then with fine sand after the hemp point is ground off, and finally ground with oil until the sealing meets the requirements and the width meets the requirements so far. The latter can only fail to meet the requirements when grinding, but it is necessary to pay attention to the operation, do not use too much force, and it is strictly forbidden to hit the valve up and down, otherwise there will be concave sand marks, which will affect the maintenance quality.
