Explosion-proof Electromotor Open-shell and Closed-shell How many types are there?

Re: motor shell open include high, but the most used of electric explosion-proof drip ( Drip-proof ), resistant to splash ( Splash-proof ) and resistant to weather conditions ( Weather Protection ) is a must Note that using this electromotor is not suitable for locations with flammable and hazardous gases. Closed-shell electromotors, which are fully sealed against gas leaks, generally fall into three categories: a fully enclosed non-air-conditioned electromotor, a cooling impeller-enclosed electromotor, and a fully-enclosed electromotor.

What is the use of explosion-proof motors in different areas?

Answer: In areas where flammable and hazardous gases are present, the use of a conventional electric motor is likely to explode due to ignition during operation or excessive heat in the shell. Therefore, explosion-proof or anti-spark alternators need to be used in these areas.The explosion-proof electromotor has special identifiers that will usually allow it to be used in hazardous areas and areas. Making sure they can be used in dangerous areas without worry.

What is the type of explosion-proof electromotor indoors?

Answer: In relation to electromotors that are suitable for use in indoor environments susceptible to fire and explosion, specific considerations and conditions have to be observed, such as if there are vapor and flammable gases in the indoor environment. Spark production should be avoided. The explosion-proof motor is usually resistant to corrosion, overheating and temperature range due to its efficiency and capability. The type of construction and design of the explosion-proof electromotor connections and their flanges are such that they have good stability against flame penetration. These fittings also have a housing that, when ignited, releases the spark gases and cools to the point where it is unlikely to explode again.

What are the types of explosion-proof electromotors?

A: The explosion-proof or spark ignition motor has two general categories, including the open-shell and fully enclosed explosion-proof motor.

How is the structure of an explosion-proof open-motor electromotor?

A: Explosion-proof electric motors have open-shell valves that ventilate the air around the coils.

How many types of open-shell anti-ignition electromotors are available?

A: The open-shell electro-explosion-proof electric motor is available in 4 different types: drop-resistant, splash-proof, weather-resistant and protected.

What types of explosion-proof electromotors are suitable for use in hazardous locations and why?

Answer: Using open-shell explosion-proof electromotors in hazardous environments such as gas mines and flammable-gas environments is not appropriate and in such environments a shielded explosion-proof electromotor should be used. The preferred reason for using an enclosed shell explosion-proof motor is that they prevent the gases inside the engine from circulating outside and around the engine, but do not completely leak the gases.

Explain the different types of explosion-proof enclosed electromotor.

A: All types of explosion-proof or spark-ignited enclosed electromotors include fully enclosed motors without air conditioning, fully enclosed motors with cooling impeller and fully enclosed motors with excessive air.

How does an anti-ignition or explosion-proof electromotor classify for hazardous environments?

Answer: Classification of materials in anti-ignition electromotors for hazardous environments is done by insurance laboratories, the National Electrical Code and OSHA .

What does anti-spark electromotor protection include?

Answer: Explosion-proof engines for hazardous environments are generally classified into three classes and categories as listed below: 
Class 1: Protect against gases, vapors and liquids 
Class 2: Protect against dust 
Class 3: Protective against fibers, acetylene, ether, hydrocarbons; fuels and, solvents and the like, metal dust, carbon dust, flour, starch, beans, combustible plastics or chemical dusts

What are the hazards that do not normally exist but which may occur unexpectedly and cause an explosion with an electric motor starter?

A: Unusual hazards include dusts that are not suspended in the air as much as they cause ignition and are present in layers of dust. These dusts may drop suddenly. To be more reliable in these environments, it is recommended that an explosion-proof electromotor be used.

Does the fiber plant need to use an anti-explosion-proof electromotor?

Answer: Fibers usually contain textiles, wooden artifacts and the like that are flammable but usually do not pose a risk of explosion. Fibers are grouped into two categories; the first are fibers that can be moved and used by manufacturers and the second are fibers that are stored and moved in storage, but only It can be done by the creators. It is generally recommended to use an explosion-proof electromotor in fiber-producing plants, especially those with adhesive factories.

On what basis is an explosion-proof electromotor classified?

A: The explosion-proof electromotor is divided into different classes (generally 3 general classes) depending on the environment in which it will be used. This class difference depends on the temperature limit and the degree of electromotor protection against gases and external factors. To learn more about electromotor protection you can contact us online for advice.

What are the CEMP Explosion Proof Motors  ?

Answer: CEMP explosion-proof electric motors  are divided into three categories: 
First category: High-voltage 
electromotor Second category: Medium-voltage 
electromotor Third category: Low-voltage electromotor

What are the features of the WEG  explosion-proof electric motor?

A: The WEG Electromotor is non -explosive and highly efficient, with a strong vibration-free design. Gearboxes are geared up to 225mm in size, have NDE DE warheads to prevent flame propagation, and are very suitable for working with inverters. They have cast aluminum shell.

What are the components of an explosion-proof electromotor?

A: The explosion-proof electromotor consists of three areas, namely the gas area, the ignition area and the ignition area. 
In the ignition zone, flammable gases and vapors are decomposed by the combustion temperature to hydrogen and carbon. It is light-weighted from this region, but the distribution over fossil-fuel ignition is relatively uniform in fossil combustible material. 
The combustion zone is that the explosion-proof electromotor reacts with oxygen in its outer boundary region, and the chemical reaction that is associated with the production of energy is exothermic, reaching the combustion temperature. Ignition temperature on ignitionelectromotor ignition zoneAffects and decomposes flammable materials. The combustion area is a small space that forms a thin coating that surrounds the flame and is, of course, the hottest part of the flame. The combustion occurs at different speeds depending on the area being burned. Usually the combustion is in a uniform state where the combustion rate is low but the ignition rate is higher when the ratio between the amount of flammable material and oxygen falls within the range of ignition.

What is needed to prevent a mine explosion?

Answer: Among the measures to be taken to prevent explosion in mines are: 
Initial explosion protection by the use of a non-explosive electromotor 
for the use of flammable liquids to 
raise the flash point for the gases in the mine 
to limit sparks in the environment 
Proper ventilation must be 
avoided before an accident occurs, and the use of an explosion-proof motor is one of the most important factors in preventing explosion in mines.

How to Avoid Flammable Liquids in Mines?

A: In addition to using explosion-proof alternators, the first step to avoid flammable liquids is to replace them with non-flammable materials; for example, we can replace water-based solvents and hydrocarbons instead of flammable liquids. Use halogen. We can also use non-flammable fillers instead of flammable pressure transducers for halogenated oils and instead of flammable powder fillers.

What is the role of limiting flammable substances in preventing an explosion?

A: In order to reduce the risk of ignition in or around an electromotor or device, we can limit or condense flammable materials, which also limits explosive space. When this limit is applied, the concentration of flammable materials should be kept below the maximum explosion or above the highest explosion limit. In most situations where steam saturation is used, condensation can be controlled by choosing the proper operating conditions for all devices. In practice, limiting concentration is preferably performed in the range between zero and below the explosion limit.

How can air conditioning prevent explosion?

A: It is generally obvious that if we were able to direct the explosive gases out of the explosive electromotor, the probability of explosion in that area would be much lower. Ventilation is one of the factors that play an important role in controlling flammable space so that we can use ventilation 
but not sustainable ventilation in the safety rooms to ensure that there is no flammable space anywhere . It can only prevent the creation of flammable space if it is possible to estimate the amount of vapors and gases emitted, and the location of the sources and conditions in which they are emitted are quite clear.

How many ventilation is done?

A: Ventilation is generally done in both natural and artificial ways. 
The natural ventilation is to renew the air that is impacted by the atmosphere, and the artificial ventilation, that is, to rotate in large quantities.

How is the explosion-proof electromotor design?

A: The design of the explosion-proof alternator must be taken into consideration, for example, the means must be such that they can withstand the greatest amount of pressure, and if there are no denotations , then the devices with AD notes issued by the German Committee for Pressure Vessels may suffice. They are consistent and their design is suitable for pressures at least eight times the absolute working pressure.

Explain the release of explosion pressure in a fire extinguisher?

A: An effective pressure relief system is usually employed if the design requirements for an explosion-proof electromotor are not met .Pressure release means an explosion in the broad sense of anything that sustains or unstable, immediately or after a certain pressure is reached by a closed device, so that the explosion occurs in a harmless way. Pressure causes the device to open, and precision is necessary to release the pressure in a non-harmful manner to prevent significant damage to anyone arising from the pressure, flame, or throwing of the pieces. The pressure should be released as far as possible in a short straight path in the open air. Pressure release devices that must be re-approved after automatic operation can only be used when their serviceability has been controlled and confirmed by explosion tests.

What is Explosion Suppression in an Explosive Electromotor?

A: After a spark occurs directly and causes a partial explosion under certain conditions with explosions occurring in the tanks, flames can be extinguished quickly by applying the appropriate extinguishers rapidly, giving maximum pressure. At least. In an explosion-proof electromotor, the suppression of the explosion is often caused by the use of optical detectors that create a thick mass of extinguishers in the foreground and eventually strangle it.

Flame Transfer How can protective equipment be used in an anti-ignition engine?

A: The explosion-proof electromotor flame may pass through the sealed parts, preventing this from occurring in a device while igniting an explosive atmosphere in the presence of an anti-spark electromotor. For example, if a reservoir of flammable liquids is protected from pressure, it is not possible to prevent the creation of a potentially flammable space, so all pores must be sealed against flame transfer.

What is the explosion-proof electromotive fitting?

A: Explosion-proof engine connections are connections that must not only prevent the blast from being exposed to the blast but also to prevent the ignition mixture from extinguishing when the ignition mixes are extinguished when it depends on actual operating conditions.

What is the role of connections in an explosion-proof electromotor?

A: The explosion-proof electromotor must permanently prevent the transmission of the internal spark of the electromotor to the combustible space. In other words, in an explosion-proof electromotor the electromotor connections must be capable of withstanding the stresses of the explosion and be able to prevent the flame from being transmitted in the accident.

What parameters do the explosion-proof electromotor have?

A: In the field of reliability of the combustion engine, tests have been carried out to determine the parameters on which these explosive motors depend. These parameters are as follows: 
Mixed 
Properties Properties How to connect 
electrical characteristics such as current, voltage and resistance.

What is the minimum ignition energy in an explosion-proof electromotor?

Answer: Since the lowest amount of ignition energy occurs in a capacitive state as opposed to an induction state, then the minimum ignition energy in an explosion-proof electromotor can be defined as: The 
smallest electrical energy that results from the discharge of the capacitor and is capable of being the most flammable Gas / air mixture in pressure? 
bar and temperature ??? ignite c is the minimum energy of a gas or steam mixture. The flammability of different mixtures of gas or air vapor increases to a maximum as the pressure first increases and then decreases again .

What effect does temperature have on the gas or air ignition range associated with an explosion-proof motor?

A: The combustion range of gas, steam, or air mixtures increases with increasing temperature, or decreases to the lowest ignition limit, and the highest combustion limit exceeds the highest combustion limit at room temperature. This temperature effect is more noticeable and also tangible than the initial pressure. Therefore, in combustible environments, in addition to the use of an explosion-proof electromotor, the ambient temperature must be considered.

What is the surface protection of an explosion-proof electromotor?

A: The outer surfaces of the explosion-proof electromotor must have standard staining including epoxy vinyl / polyamide paint and not less than 50 μm thick. The explosion-proof engine will also be able to perform according to the order in which the special paint process is made of polyacrylic paint. Dyes which contains RAL 5010 and RAL other or MUNSEL should also be available to order.

What should be the internal surfaces of an explosion-proof electromotor?

A: Usually in an explosion-proof electromotor, the motor of the device is provided on the interior surfaces with anti-heat mode.

By what standard do the humidifier holes apply?

A: In an explosion-proof electromotor they will be capable of operating according to the order of the humidifier holes of size 160 onwards.
