Screw machine explosion-proof mainly need to consider the following aspects:
first of all, due to the unique structure and working principle of the screw machine, it has the requirement of explosion-proof. For screw machines working in flammable and explosive environments, their motors need to meet explosion-proof requirements. Common explosion-proof motors include flameproof type and increased safety type. Flameproof motors take measures to isolate components that may form sparks, arcs or high temperatures from combustible gases inside the motor; while safety-increasing motors use special measures in electrical circuits, such as current limiting and reducing current density to prevent Arc.
Secondly, the sealing structure of the screw machine is also the key to explosion-proof. When working in a flammable atmosphere, the sealing performance of the pump is particularly important. Can use packing seal, and by increasing the packing material selection, improve the sealing structure and other methods to improve the sealing of the pump, in order to prevent flammable gas leakage. In addition, a higher-level sealing structure such as a mechanical seal or a magnetic seal can be used to enhance the explosion-proof effect.
Thirdly, for the screw machine working in a flammable and explosive environment, the shell and internal transmission parts should be made of explosion-proof materials. Common explosion-proof materials include stainless steel, cast aluminum alloys, etc. These materials have good corrosion resistance and high temperature resistance, and can operate stably for a long time in dangerous environments.
Finally, some auxiliary measures are needed to enhance the explosion-proof performance of the screw machine, such as installing an explosion-proof limit switch. When the working state of the pump is abnormal, the power supply should be cut off in time to avoid failure. At the same time, explosion-proof sensors and alarm devices are installed around the pump to realize intelligent monitoring and remote control.
To sum up, the explosion-proof of the screw machine needs to meet the explosion-proof requirements of the motor, a good sealing structure, the use of explosion-proof materials and equipped with auxiliary measures. These measures can ensure the safe operation of the screw machine in a dangerous environment and effectively prevent the occurrence of safety accidents such as fire and explosion. At the same time, in practical applications, it is also necessary to select the appropriate screw machine and corresponding explosion-proof measures according to the specific working environment and explosion-proof requirements.
Nitrogen in the semiconductor factory is bodyguards, cleaners, porters and air conditioners, while the water-lubricated oil-free screw air compressor is the source that provides clean raw materials for the nitrogen machine. The source is not clean, and the back is completely useless.
The frequency of air compressor drainage mainly depends on the use of environmental humidity, working load and storage tank capacity and other factors. The following are some specific drainage time recommendations: 1. the drainage time in the regular use environment. In the regular use environment, it is recommended that the air compressor every 5 to 1
The environmental core of explosion-proof air compressor is to eliminate all ignition sources. Water lubricated air compressor is naturally more suitable for this dangerous environment than oil injection machine because there is no oil.
The rated pressure of the air compressor refers to the maximum pressure value that the air compressor can withstand under normal working conditions. When the rated pressure of the air compressor is 8bar, the minimum operating pressure is not a fixed value, but will be affected by many factors.
In the choice of air compressor, centrifugal and screw are two common types. According to the demand of air consumption, the following are some suggestions to help you determine which type of air compressor to choose: 1. The stability and fluctuation of air consumption centrifugal air compressor:
The frequency conversion screw machine is a kind of equipment that can adjust the operating frequency and speed. It combines the frequency conversion technology and the working principle of the screw machine. The following is a detailed explanation of the main functions and uses of the frequency conversion screw machine: Working principle: Screw machine part: Screw
In the food industry, compressed air quality is directly related to product hygiene and safety. Compressed air for food must meet a series of strict quality requirements, including no oil, no water, no dust, no microbial contamination, etc., to ensure that the food is not contaminated during the production process
The pressure in actual industrial production varies depending on the production process, equipment type, production demand and other factors, and there is no uniform standard value. The following are some specific analysis and generalization of pressure in actual industrial production: the importance of 1. pressure in industrial production pressure
Oil injection air compressor is a kind of mechanical equipment that uses electric motor to drive air compression device. Its product structure mainly includes electric motor, compression mechanism, intake system, exhaust system, cooling system and lubrication system. In the working principle, the fuel injection is empty
Trouble phenomenon: When the engine is running and the air compressor is inflating the air tank, the air pressure indicator indicates that the air pressure cannot reach the starting pressure value. Causes of failure: 1. The barometer fails. 2. The transmission belt between the air compressor and the engine is too loose and slips, or
