The shredding of mechanical and electrical machines at high temperatures to maintain talent through the hot summer. Nothing can be done in the sun, and it's the shredder of our work! Shredding machine is not a necessary equipment in the processing of waste materials, and the motor is the primary base of equipment. If the motor fails then the equipment can't function properly, so protect the motor area.
How to clean up the defects of mechanical and electrical machine, the following manufacturers teach you several small good methods.
1, motor department check if motor bearing excessive wear or device adverse, constitute and rotor rub, make the surface damage of the iron core, which constitutes a short circuit between silicon steel sheet, motor iron loss increase, make the motor temperature rise too high. Then use fine file and other things to remove the burr, remove the silicon steel plate, clean and then put on the insulating paint, and heat the drying.
2. When working at high temperature, check the connection between the iron core and the seat of the motor, and tighten the original positioning screw. If the positioning screw fails, the positioning hole and tapping screw can be redrilled in the seat. The shaft of the bearing defect is supported by the bearing, which is the heaviest load, and the part that is briefly worn.
With the development of science and skills, a great deal of knowledge of metal breakage has been achieved. Large particles of metal are selected
A different kind of crushing method, which can be obtained by several micron metal, with a variety of skills.
In industry, the widely used metal crushing method is still mechanical force crushing, the first is kneading, breaking, breaking, grinding and impact crushing. Non-mechanical crushing has not yet been used in large industrial production.
Under the effect of external force, the stress of the attack reaches its ultimate strength and the metal is broken. There are several methods for shredding mechanical force.
A crushing: place the metal between two kneading surfaces. After casting, the compression strength of the metal is broken due to the pressure of the compressive stress.
B split pieces: the metal placed between a plane and a tooth, when applying kneading force, metal tensile stress in the attack, because of its arrived in tensile strength, tensile stress is along the force direction of fracturing effect.
C break: place the metal between the two teeth of the yuan, when the kneading force is applied to the bending strength of the material, the metal is broken.
D impact crushing: metal is broken by the impact of high speed rotation. This method can be done in many ways. Because of the shi
The force is instant effect. The deformation is not extended to the parts of the hit object. It only has a large part of the stress in the affected area, and it breaks down along the internal microcracks. Therefore, the dynamic load has more crushing effect than static load.
E pulverize: place the metal between two relative working surfaces, apply pressure and shear force together, and the metal is broken when the shear stress of the attack reaches its shear strength limit.
In fact, all kinds of shredding machines in the process of crushing metal are the effect of several crushing methods. However, there must be one or two methods of casting and other crushing methods. Due to the different physical and mechanical properties of various metals, the force method of shredding machine should be applied to metal mechanical properties. The metal of all kinds of hardness is used to break apart or cooperate break to break up to be appropriate, if use ground to break, machine piece wear serious; For brittle metal, it is advantageous to use breaking, bending and crushing crushing. If it is damaged, the fine powder will increase in the metal. It is suitable for the use of grinding and breaking methods for the selection of durable and viscous metals.
