Explosion proof Roots blower is a special type of blower designed for flammable and explosive places. The following is a detailed introduction to it:
1、 Definition and Characteristics
1. Definition: Explosion proof Roots blower refers to a special type of blower with explosion-proof and explosion-proof functions used in flammable and explosive places.
2. Characteristics:
Capable of working normally in harsh environments such as high temperature, high pressure, and flammable gas environments.
The use of explosion-proof motors and special material made fan blades ensures stable operation of the equipment.
Sealing performance, preventing the invasion of harmful gases from the outside, and protecting equipment and personnel.
2、 Working principle
The working principle of explosion-proof Roots blower is based on the basic structure of Roots blower, which is that two interlocked impellers rotate relative to each other inside the casing, thereby compressing gas from the inlet to the outlet. Due to the gaps maintained between the impellers and between the impellers and the casing, there is no internal compression process, and the amount of gas transported is proportional to the rotational speed. This design ensures stable gas delivery and can operate under high pressure and high temperature conditions.
3、 Application Fields
Explosion proof Roots blowers are widely used in various explosive hazardous areas such as petrochemicals, coal mines, oil fields, oil depots, chemicals, machinery manufacturing, electricity, and light industry. It has a high explosion-proof rating and corrosion resistance, can withstand harsh environments and high temperature operations, and also has fast and fast speed control capabilities, as well as good maintenance performance.
4、 Purchase and maintenance
Selection factors:
1. Power and speed: Choose the appropriate power and speed according to the real needs of the usage scenario.
2. Air volume: The larger the air volume, the faster the air flow and the higher the cleanliness. Users can choose according to the size of the space and the requirements of the usage environment.
3. Noise and vibration: High quality explosion-proof Roots blowers should have a noise level of less than 70 decibels and low vibration levels.
4. Energy consumption: Energy consumption mainly depends on power, and when choosing, attention should be paid to its energy consumption situation.
Daily maintenance:
1. Regularly check the various operating parameters of the equipment, such as air volume, pressure, temperature, etc., and promptly detect and handle abnormal situations.
2. Regularly clean the equipment, especially the air inlet and filter, to prevent dust and impurities from entering and affecting equipment performance.
3. Regularly replace lubricating oil to maintain the lubrication status inside the equipment.
4. Regularly inspect explosion-proof motors and control systems to ensure their explosion-proof performance remains good.
5、 Common faults and solutions
Explosion proof Roots blowers may encounter some common faults during operation, such as insufficient air flow, unstable pressure, abnormal noise, etc. The following measures can be taken to address these faults:
1. Insufficient air volume: Check if the air inlet is blocked and if the filter needs to be cleaned or replaced.
2. Unstable pressure: Check whether the impeller is worn or the clearance adjustment is improper, repair or adjustment is needed.
3. Abnormal noise: Check if the bearings are damaged or poorly lubricated, and replace the bearings or replenish lubricating oil.
In summary, explosion-proof Roots blowers, as a type of gas conveying equipment, have important application value in industrial production. By understanding its working principle, explosion-proof function, selection elements, installation and debugging, daily maintenance, and common fault handling, its performance can be better utilized to ensure that the equipment operates in high-risk environments.
