According to the Beijing Public Transport Group, 120 new dual-source trolleybuses in the Beijing public transport system have been put into operation in recent days. These new dual-source trolleybuses use lithium-ion battery technology.
According to reports, compared with the traditional lead-acid batteries, the lithium-ion battery has a cycle life of 5 to 6 times, which is more energy-saving and environmentally friendly. The average lead-acid battery has a service life of up to 1 year, and the lithium battery can be used for 5 years. the above. At the same time, the lithium battery has a longer battery life. Under normal conditions, it can be driven away from the network for about 8 kilometers. When the vehicle encounters special conditions such as serious congestion and road construction, it can take corresponding bypass measures to enhance flexibility. And mobility. In addition, the new trolleybus can charge the vehicle lithium battery through the wire network when the line is running, without having to build a charging station separately, eliminating the need for land, equipment and other resources necessary for the construction of a dedicated charging station. By the end of the year, Beijing Public Transport Group will also have 60 new lithium-ion battery dual-source trolley buses on the road.
Boiler Production Cutting Machine
The CNC plasma cutting machine is a desktop gantry structure. The whole work surface of the machine adopts the integral rim structure, which has the characteristics of stable and reliable operation and long service life. The model adopts optical axis linear guide and bilateral drive. It can realize the cutting of any metal materials according to any pattern, and it is suitable for the rapid CNC cutting of carbon steel plates, aluminum plates, copper plates, stainless steel plates and other workpieces with medium and thin plates. The effect is good, no dross and burrs are used; Directly use Wentai software or AutoCAD drawing software to directly draw graphics, without conversion, direct cutting, and can be simple to discharge, the workpiece is set side by side. At the same time, it also solves the problem that the thin plate and the thick plate cannot be compatible. This machine comes standard with plasma cutting method, equipped with arc-pressure automatic height-adjusting system and torch anti-collision system. It is also equipped with a set of water spray cooling device to reduce the thermal deformation of thin plate cutting; this type of equipment is cutting and cutting equipment for sheet metal processing industry and ventilation pipe industry.
