At present, there are two types of domestic electric anti-explosive forklifts: First, the whole machine design and manufacturing, the second is to explosive modification on ordinary electric forklifts, and due to the technical performance of different electric explosion-proof trucks due to design philosophy, it is necessary to use electricity The technical characteristics and technical standards of explosion-proof forklifts are to determine the scientific design ideas.
1, electric explosion-proof forklift integral design concept
In one sentence, the contradiction caused by the backwardness of the domestic electric anti-explosive forklift design concept is "first require good electric forklift, require good explosion-proof performance; or first require good explosion-proof performance, and require good electric forklift". This sentence itself illustrates two problems in the domestic electric anti-explosive forklift: First, because the electric forklift itself is poor, even if there is a good explosion-proof design, it is not required because of the performance of the whole machine; The electric forklift itself is good, but the performance of the whole machine can be reduced after the explosion-proof modification. It is the above reason that we must establish the overall design concept of electric explosion-proof forkrs. According to the advanced electric anti-explosive forklift technical standards, the combination of good electric forklift design and advanced explosion-proof design can create a superior product. To do this, you must follow the following design principles.
a) Design performance requirements for electric explosion-proof forklifts are higher than that of ordinary electric forklift design performance requirements.
Electric explosion-proof trucks are high for insulation, conductivity, temperature, circuit short circuit, and current, etc., such as motors, electrical components, in the explosive body, the difference in heat dissipation causes temperature rise, if the circuit design is unreasonable, it is easy to cause The circuit is short-circuited. If the load current of the whole machine is large, there will be problems such as overcurrent, temperature rise, high electrical wires, and decline in insulation, resulting in poor explosion-proof performance of electric explosion-proof forklifts, even if there is a protection means to stop operation, It will result in shorter operating time, long maintenance time, short service life.
Domestic general electric forklift technology is generally low. If explosion-proof design is performed on this, it is certain that there will be no good explosion-proof machine performance, and the technical performance of explosion-proof modification can be reduced, so the first thing to design it in the design concept. Quoted new technology to improve the technical level of electric forklifts, but also innovative design ideas to design a system that meets explosion-proof characteristics, which does a low current, low temperature rise, low noise, high efficiency, high intelligent control.
b) Active protection technology design and passive explosion-proof means combined.
Generally, the design commonly used technologies for domestic electric explosion-proof trucks are taken by the explosion-proof type, this security, and increase security type, and the explosion is used to prevent the explosion. After the explosion, there is also a simple and reduced as possible in the circuit design. The line and reduce the spark control point, the lack of aging, insulation performance, etc., the safety hazard is large.
The so-called active protection technology is combined with advanced sensing, short circuit protection, insulated monitoring and other electronic components and intelligent control systems in the whole machine circuit design. This can be done through the program to set the explosion-proof technology. Automatic control avoids artificial hazards. And can be controlled by thermal rise, heat drop and secondary current limiting control, and the operation of the vehicle can be controlled and the working time can be extended.
c) Rational application of advanced explosion-proof technology to develop explosion-proof supporting products.
In the electric explosive forklift design, it is necessary to keep up with the international advanced technology development, especially the development of electronics, hydraulic technology, such as electronic monitoring products, hydraulic wet braking, etc., is not available in domestic technology, in reasonable application At the same time, we must conduct technical cooperation with domestic related professional manufacturers. Develop key technical products to realize localization, cooperative development must have its own technical design and master core technology key and supporting manufacturers to carry out close technical collaboration, so that there will not be developed The product is not relatively low in domestic manufacturers' technical platforms.
