Commonly used crusher knowledge of repair and maintenance

A, the concept of crusher:

Crusher is refers to the ability to use external forces is the material deformation and split into smaller particles called grinder machine. The crusher has been widely used in all walks of life. In view of the crusher is the basic processing technology of production and application of Chinese medicine, superfine grinding has increasingly aroused people's concern, though started late, developed varieties is relatively small, but show unique advantages and broad application prospects.

Second, the grinder repair and maintenance:

As a result of the mill working principle is different, so the development of the mill also presents a pluralistic development, types of increase inevitably leads to the emergence of various problems, below I will be more common on the market principle and how to solve the problems of several kinds of crusher, and daily maintenance are simple introduce!

(1) and the problems existing in the mill:

Now appear on the market a lot of mill, it can cut high feed ivy leaves, stem, shredded red tiaoxi, corn, is rural commonly used machinery. The machine longer duration of use, often appear the following failures: 1, shattered work weakness; 2, do not start; No electricity.

(2), mill maintenance: (usually can overhaul).

1, first check the power supply socket, plug, power cord presence of oxygen, fracture, without can be plugged in commissioning,

2, when the electric motor does not rotate, with handle gently toggle wheel and rotates, it is concluded that the machine one of the two starting capacitor capacity caused by failure. This kind of circumstance usually only in new products.

3, another is not turn electricity, applying force to rotate but emit a weak current in the motor noise, is to start the capacitance caused by slight leakage. If the current noise is too large, the motor can't start, conclude that start capacitance caused by short circuit (motor coil short-circuit is professional repair). In the absence of professional instrument, can remove the first capacitor (4 uf / 400 v), the two respectively inserted into the mains lead to the capacitance in the zero-sum wire socket charging, then remove the two wire short circuit discharge. If this can spark discharge, and there were loud sound "pa", shows that the capacitance can be used; If the spark and noise is weak, the capacity of capacitance have fallen, need to change new, or add a small capacitance. If the capacitance short circuit will not be able to use this method have been damaged, and must use the same specification product substitution can repair.
