In January 2020, a new type of coronavirus broke out in Wuhan, China. Due to problems in prevention and control, coupled with large spring festival traffic, the new type of coronavirus cases appeared in the country, which greatly threatened people’s health, but also brought serious economic impact on all walks of life.

In view of the strong infectivity of the new coronavirus, in order to avoid more patients and infected personnel, the state issued a policy to postpone the resumption of work for enterprise personnel. The Spring Festival holiday, which was originally scheduled to end on January 31, 2020, is now postponed to February 10, 2020.

For the postponement policy of resumption of work, major enterprises are facing severe challenges. There is a significant decline in the order volume of aluminum industry, and the production volume is also affected. The delayed resumption of workers makes enterprises have to stop operation and only rely on Inventory for transactions. It is expected that after the resumption of work, aluminum enterprises will slowly resume normal work order, but during this period, the price of aluminum products may rise.

Although affected by the epidemic, aluminum enterprises can only postpone the resumption of work, but the production of special aluminum profiles for medical equipment companies are rushing to work day and night. In order to overcome the epidemic situation as soon as possible, the company not only recalled the health workers in the rest period, but also accelerated the production process to provide enough medical equipment for the medical front line.

So far, aluminum companies still have good expectations for the market after the outbreak and hope that China’s epidemic will pass as soon as possible.

Reminder:

Wash your hands, wear masks, go to bed early and get up early to enhance your immunity and fight against the epidemic. Jiangyin Mingding company will work with you.

The motor is the starting core of various industrial machines. It is as important as the human brain. Once a problem occurs, it will cause damage to the machine, which will affect the production process. Therefore, it is necessary to regularly check whether the motors of important industrial machines are normal. The failure of most motors is mainly due to the problems of the motor stator insulation. How to troubleshoot and solve the motor stator insulation problems can be solved by the following methods.

First we understand the insulation of the synchronous motor windings. Synchronous motor winding insulation includes inter-strand, brake, row, and layer. Insulation members for supporting or fixing at various ends, and insulation of connection wires and lead wires. Different insulation materials or process methods constitute different insulation structures. The insulation structure mainly plays a role of isolating electricity. In long-term operation, due to the effects of electricity, heat, machinery and different environments, the insulation gradually ages, making the motor unable to operate safely. Therefore, the absolute insulation is important to determine the operation of the motor. factor.

The stator insulation problem of synchronous motors is manifested in two aspects: on the one hand, the stator insulation is damaged, and it is manifested as local and coil insulation damage. Damage to the ground insulation in the coil, damage to the slot exit of the coil, damage to the coils on the end ferrules, and phase-to-phase insulation damage; on the other hand, the performance of the insulation has deteriorated to the extent that it cannot meet the basic requirements for certain operations. The degradation of insulation performance is mainly manifested in the reduction of stator insulation resistance and absorption ratio. It also shows that the leakage current value is too high during DC withstand voltage, three-phase imbalance, DC withstand voltage breakdown, AC withstand voltage breakdown, etc. .

The conventional test method is to measure the stator insulation resistance and absorption ratio with a megohmmeter. This is the most direct inspection method commonly used, and the DC withstand voltage leakage test can further check and find insulation defects. In most cases, the insulation can be broken down. Find or find defects before.

If the above two methods have not found a problem, you can use the AC withstand voltage test. Its test voltage is consistent with the frequency of the working voltage waveform. It is a reliable method to check and test the insulation of the motor. The decrease in insulation performance is generally divided into a general decrease in the insulation performance of the motor coil and a partial, individual coil performance decrease.

The problem of finding the insulation point of the motor is obvious in the accident state. In order to ensure the normal operation of the motor, please find the fault point according to the above methods. The insulation problem seriously affects the operation of the unit. If it is not handled properly, it is often the condition that caused the accident.

Connector is a common small part in our life, but we can only see its overall shape, generally it is not disassembled. What are the components of the connector? What is the basic structure of the connector? Let’s disassemble the connector and observe its internal composition.

①Contacts. It is the core part of the connector to complete the electrical connection function. Generally, it is composed of anode contact and cathode contact, and the electrical connection is completed through the insertion of cathode and anode contact. The anode contact is a rigid part, whose shape is cylindrical (round pin), square (square pin) or flat (insert). Anode contact parts are generally made of brass and phosphor bronze.

The cathode contact is the jack, which is the key part of the contact pair. Depending on the elastic structure, the elastic deformation occurs when the pin is inserted, and the elastic force is generated to form close contact with the positive contact piece to complete the connection. There are many types of jacks, such as cylinder type (slot, necking), tuning fork type, cantilever type (longitudinal slotting), folding type (longitudinal slotting, “9” type), box type (square jack) and double-sided wire spring jack.

②Insulator. Insulator, also known as base or mounting plate, is used to arrange contacts according to the required position and spacing, and to ensure the insulation performance between contacts and between contacts and shell. Good insulation resistance, voltage resistance and machinability are the basic requirements for selecting insulating materials to be processed into insulators.

 ③Shell. The shell, also known as the shell (depending on the variety), is the outer cover of the connector. It provides mechanical protection for the inner insulating mounting plate and the pin, and provides the alignment when the plug and the socket are inserted, so as to fix the connector to the equipment. Appendix. Accessories are divided into structural accessories and installation accessories. Structural accessories such as clamp ring, locating key, locating pin, guide pin, connecting ring, cable clamp, sealing ring and gasket, etc. Install accessories such as screws, nuts, screws and spring rings. Most of the accessories are standard parts and general parts.

The general connector is mainly composed of these three parts, but there are also some special connectors, which need to increase the devices to improve its utility. What else do you want to know about connectors? Welcome to our website:www.szsantian.com
