The motor is a device that converts electrical energy into mechanical energy. No matter how the size and type of the motor are divided, there are two components—the rotor of the motor and the bearing housing of the end cap. The motor end cap is the main component that supports the rotor and is generally cast iron. It is widely used on motors because of its easy processing and high cost performance. Motor FAQs: The motor end cap bearing chamber wear and motor shaft bearing position wear often occur during motor operation. The reason for the wear of the bearing housing of the motor end cap: 1. Processing error, resulting in clearance; 2. Disassembly and installation are not standardized, causing damage and wear to the bearing chamber; 3. With inadequate contact surface, causing metal fatigue; 4 bearing damage, causing the bearing chamber to wear Repair technology to solve the wear of motor end cap bearing chamber: The existing measures to solve the wear of the bearing housing of the motor end cap are mainly based on replacement, but for some enterprises with a small amount of wear, copper pads and grinding points are used to quickly repair and resume production. Other machining units also use nesting measures. This method is only used when there are no spare parts for some motor end caps. Emergency mats and repairs can only solve short-lived moments. The motor will quickly wear and intensify the wear under load and operation, causing the motor to vibrate and affect the safe operation. How to repair quickly The wear of the motor end cap bearing must first understand the cause of the wear of the motor bearing housing and the effective control: Metal wear is caused by normal wear and tear of the metal. This is an inherent characteristic of the metal. The second problem is the relationship between the parts. No matter how high the precision of the part is in the machining process, the matching of the part's mating surface can never be achieved. From the microscopic observation, the metal mating surface can only be 30% -50%, so the force surface of the mating part is also one of the root causes of metal fatigue and wear. Sole carbon nano polymer repair motor bearing room new technology: The characteristics of carbon nano-polymer repair technology, first, the technology is essentially different from the traditional repair process, can not rely on metal thinking to be treated, is a new type of application technology; the second is the motor operation, mainly subject to various pressures and The impact of impact, carbon nano-polymer material repair wear is about comprehensive mechanical properties, that is, the metal has the elastic deformation and toughness, stiffness, etc., the material can withstand pressure 1200 kg per square centimeter, can fully meet a variety of shaft operating pressure And intensity requirements. In addition, since carbon nano-polymers are paste-like, after repair, they can completely achieve 100% surface coordination and avoid the occurrence of gaps. Thirdly, Sole carbon nano-polymer materials can be machined after milling, milling, planing, grinding, and so on. Through different repair measures, the bearing chamber wear size can be restored.

Dichloromethane has a broad spectrum of solubility, low boiling point, relatively lowest toxicity, and relatively best reaction inertia, making it the most frequently used organic solvent in organic synthesis. As a solvent, its status is almost equivalent to that of water in inorganic salt chemistry. Dichloromethane, the raw material for organic synthesis, is inert due to the three-dimensional Electronic effect and usually does not participate in chemical reactions. However, it can also participate in the reaction under certain conditions. In industry, there was an accident that residual dichloromethane reacted with sodium azide in N, N-dimethylformamide to produce methane azide, which led to factory explosion.
