In 2005, Jilin Petrochemical Company's double-benzene plant suffered several major explosions. According to the investigation, the P-102 tower of the plant was blocked, the circulation was not smooth, and the explosion was caused by improper handling. Similarly, diesel and battery vehicles carrying flammable substances can sometimes explode, which is not alarmist. In the past, many explosions and fires in the petroleum, chemical, paint, pharmaceutical, and arms industries were mostly identified as non-explosive vehicles. Therefore, the important role and status of explosion-proof technology in the forklift market is increasingly apparent.
New requirements for explosion-proof motors in the new era
Compared with foreign countries, there are still some gaps in China's explosion-proof forklift technology. The main problems are: some products safety performance and sanitation indicators can not meet the standard requirements; poor product reliability, high early failure rate; unstable main performance; special forklift Insufficient research and development capabilities, lack of corresponding development and development according to different loading and unloading objects and different working conditions.
Therefore, according to different production environments, it is very important to use different explosion-proof technologies for vehicles, especially in special working environments. Explosion-proof technology must be excellent when handling goods in an explosive environment.
According to the current domestic and international technological developments, the basic protective measures include: installing a flame arrester and an exhaust spark eliminator in the intake and exhaust systems of the diesel engine; controlling the surface temperature of the vehicle and the exhaust temperature of the diesel engine, making it not high The temperature group values ​​specified in the explosion-proof forklift; the electrical components such as the forklift starter motor, motor, battery, switch and instrument take protective measures to eliminate or control the arc and spark; use antistatic belt, tire, non-metal fan and counter The fork and the car body adopt anti-collision spark measures; the independent automatic control system is used for over-temperature, over-speed and leakage protection; and the concentration of the explosive mixture in the working area is effectively monitored.
Successful application of domestic new explosion-proof technology
At present, domestic explosion-proof technology has a very successful application model. Zhejiang Jiali Technology Co., Ltd. is a private high-tech enterprise operated by a multinational company. It was originally a traditional pump factory and its products are mainly used in the petroleum and chemical industries.
The CPDY-FB explosion-proof full hydraulic electric series forklift produced by Jiali Technology belongs to the new generation of logistics handling engineering machinery equipment, and has been included in the national science and technology innovation project and obtained the national invention patent. This technology changes the traditional three-motor drive to single motor drive, and the electric speed control is hydraulic speed control. It has the characteristics of simple structure, flexible control, good fretting performance and high explosion-proof safety performance. It can be widely used in petroleum and chemical industry. Handling, handling operations of goods in inflammable and explosive places in special fields such as national defense, civil aviation, and medicine.
When seeing the new explosion-proof technology developed and produced by China itself, Su Enyi, secretary general of the China Construction Machinery Industry Association Mobile Industrial Vehicles Branch, said that although Jiali Technology is a latecomer to the forklift production industry, Jiali Technology has identified the market demand. Specializing in R&D and production of explosion-proof forklifts, in many production enterprises in China, high starting point, accurate market positioning, production of high-tech, professional and explosion-proof forklifts, with unique positioning, advanced technology, there are reasons to become forklifts The industry's "later people".
Explosion-proof forklifts are high value-added and high-tech products. Chinese companies must catch up with international forklift giants, not only in line with foreign forklift manufacturers in terms of quantity and scale, but more importantly, speed up the gap in explosion-proof technology and innovation. .
