China's explosion-proof electric heater products started relatively late, around the early 1950s, beginning with the imitation of former Soviet Union's coal mine explosion-proof electric heater products, gradually developing and forming a certain industry production capacity. So far, there are about 300 manufacturers with an annual output value of over 2 million yuan, producing more than 200 types of products, basically meeting the needs of the electromechanical product market and playing a significant role in China's national economic development.
Explosion-proof electric heater, as the name implies, is an electrical appliance that can prevent explosion accidents in places containing explosive dangerous gas mixtures. Currently, China's explosion-proof electric heater is basically divided into two categories: one is called mining explosion-proof electric heater, mainly used in coal mines and mines with prominent explosive gases such as methane; the other is called factory-use explosion-proof electric heater, mainly used in all places except mines and coal mines, such as petroleum, chemical, light textile, pharmaceutical, military and other enterprises, including gas explosion-proof and dust explosion-proof electric heater.
Since explosion-proof electric heater is a special electrical product, the state has formulated mandatory implementation standards for it. This is an important guiding document to standardize the technology and quality of China's explosion-proof electrical products, and also an important basis for the production, use, and inspection of China's explosion-proof electrical products. Any explosion-proof electric heater must meet its standard requirements and obtain the product certificate "Explosion-Proof Inspection Certificate" issued by the explosion-proof inspection unit before entering the market. In recent years, the economic development of petroleum and chemical enterprises has been rapid, and the demand for factory-use explosion-proof electric heater has also increased relatively. Explosion-proof electric heater products have relatively complex production processes and are difficult to manufacture, but the profits are also considerable. Therefore, more and more manufacturers are producing explosion-proof electric heater. The nature of these explosion-proof electric heater manufacturing enterprises has shifted from the past dominance of public ownership to the current situation where 60% to 70% are non-public enterprises. In the process of China's economy transitioning from a planned economy to a market economy, the weakening of industry management and insufficient law enforcement supervision of product quality have led many manufacturers to switch to producing factory-use explosion-proof electric heater. Driven by huge economic interests, many enterprises have started production arbitrarily, and many have not even understood the basic theories and knowledge of explosion-proof electrical equipment before hastily starting production, which inevitably brings huge hidden dangers to the explosion-proof electric heater product market. In addition, some enterprises, driven by profit, arbitrarily deviate from explosion-proof standard requirements to seek greater economic benefits. It can be said that the current explosion-proof electric heater market competition is very fierce, almost to the point of white heat. In such an unordered and non-standard competitive production environment, we cannot fail to see that factory-use explosion-proof electric heater has a large number of problems in the entire process of technology development, production, management, and sales. There are inevitably some fake, shoddy, inferior, and overpriced products. Therefore, we must have a sufficiently clear understanding of the entire industry status of factory-use explosion-proof electric heater.
China's factory-use explosion-proof electric heater products are currently in a new period of development. We should take advantage of this very favorable opportunity to greatly improve the technology, quality, structure, performance, and appearance of China's explosion-proof electric heater products. Especially in conjunction with the upcoming issuance of production licenses for explosion-proof electric heater products, we should eliminate a batch of production enterprises and products with backward technology and low quality, strengthen industry management, and strengthen technical quality supervision. China's explosion-proof electric heater products will surely develop rapidly.
