Basic information
Coal mine is divided into open pit mining and underground mining, and its equipment is naturally divided into open pit coal mine machinery and underground coal mine machinery.
According to statistics, at the end of the 11th five-year plan, China’s coal demand id about 90 billion yuan. Of these, about 70 billion yuan is invested in new coal – making equipment, and about 15 billion to 20 20 billion yuan is needed for technical renovation. According to the statistics o f115 major coal companies in China, the output value of 2007 was 49.61 billion yuan, with sales revenue of 48 billion yuan. In 2008, the annual output value was more than60 billion yuan, with sales revenue of more than 60 billion yuan. This means that China still has about 30 billion yuan of coal machine products market competition space, in which the production capacity of more than 6 million tons is larger.
The demand of large mining equipment will become mainstream.
The state council “ several opinions about accelerate the development of the equipment manufacturing industry, points out that to the development of large coal mine comprehensive mining, lifting and washing equipment, realize large-scale integrated mining, lifting and washing equipment”. During the 11th five-year plan period, the mechanization degree of large -scale coal mining equipment in China should reach more than 95%, and the medium-sized coal mine should reach more than 80%. In addition to the large coal mining group’s merger and reorganization of small and medium-sized coal mines, large mining equipment needs more.
1. Open-pit coal mining machinery: a continuous excavator, mechanical excavator, large coal crusher, large belt conveyor, large non-highway mine, etc.
2. Mining machinery for underground mining: with the increase of mining mechanization and the requirement of coal mine safety, the mining equipment is the main composition of coal mine machinery.
① Coal mining equipment: drum coal mining machine, continuous coal mining machine, planer, screw coal mining machine.
② Conveying equipment: belt machine, scraper conveyor, scraper reloader.
③ Working face support equipment: hydraulic support, single prop
④ Roadway tunneling equipment: rock driving machine, semi-coal mining machine, hard rock driving machine.
⑤ Ventilation equipment: main ventilator, local ventilator
⑥ Roadway support equipment: hydraulic anchor drilling rig, pneumatic anchor rigging drill, pneumatic support bolt drill, leg type pneumatic support bolt drill, strut support pneumatic hand-held drill.
⑦ Gas exploration equipment: pneumatic pedestal bolt drill, coal mine tunnel drilling rig, coal mine mud pump.
⑧ The motor stable power supply chain is extremely important.

Efficient AC to DC Converter for LED: Transforming 12V AC Power into DC for Enhanced Lighting
Introduction: In recent years, there has been a significant rise in the popularity and demand for LED lighting due to its energy efficiency and longer lifespan. However, LEDs require DC (direct current) power to operate, while the standard power supply in most homes and offices is AC (alternating current). Therefore, an efficient AC to DC converter is necessary to transform the 12V AC power into DC for enhanced lighting. This article explores the importance of such a converter and its benefits in the field of LED lighting. Understanding AC and DC Power: Before delving into the details of AC to DC conversion, it is crucial to understand the fundamental differences between AC and DC power. AC power, or alternating current,...

AC DC power supplies are essential components in many electronic devices and systems. They provide a stable and reliable source of power to ensure the proper and safe operation of the equipment. Among the various types of AC DC power supplies available, the power factor correction (PFC) series is one of the most efficient and widely used. The PFC series is designed to correct the power factor of the AC input to a high value, typically above 0.9. This means that the power supply draws less current from the AC mains for the same output power, resulting in lower power consumption and reduced energy costs. In addition, the PFC series reduces the harmonics and noise generated by the power supply,...

Industrial AC-DC Converter: Transforming Power for Industrial Applications
In today's industrial landscape, the efficient and reliable conversion of alternating current (AC) to direct current (DC) is of paramount importance. This is where industrial AC-DC converters come into play, as they play a crucial role in transforming power for a wide range of industrial applications. From manufacturing plants to transportation systems, these converters are indispensable in ensuring the optimal functioning of machinery and equipment. The primary function of an industrial AC-DC converter is to convert the high voltage AC power supply into low voltage DC power that can be used by various industrial devices. This conversion is necessary because many electronic devices and machinery in industrial settings operate on DC power. By providing a stable and regulated DC output,...

Hvad skal man overveje, når man vælger modulstrømforsyning?
Uanset hvad vi køber i vores daglige liv, vil vi i lang tid skulle overveje, ikke kun sammenligningen, men også kvaliteten af alle aspekter. Derfor, når vi vælger at bruge DC-DC-modulets strømforsyning, skal vi ud over den mest basale spændingskonverteringsfunktion også overveje følgende aspekter: 1. Maksimal effekt Det foreslås generelt, at den specifikke applikations udgangseffekt skal være 30~80% af den nominelle effekt af modulets strømforsyning. Inden for dette udgangseffektområde skal egenskaberne for alle niveauer af modulstrømforsyningen udnyttes fuldt ud, som er rigelige og stabile. For klar belastning fører til luksusspild af ressourcer, for høj temperatur og troværdighed af...
