The national policy responds to energy conservation and emission reduction. The international environment requires us to save energy and reduce emissions. Therefore, almost all production and sales companies in the field of construction machinery are playing energy saving and environmental protection cards. How can we achieve energy saving and emission reduction and respond to current policies? Here we briefly introduce the application of energy-saving technology in concrete pump trucks for concrete pump truck engines.
The core of energy saving and emission reduction of concrete pump trucks is the engine
One of Engine Energy Saving Measures: Cooling Fan
The multi-level control of the cooling fan is accompanied by the technical development of the truck engine. In the engine thermal management system, the fan design of the cooling system has also undergone a lot of changes. It has mainly experienced three stages: early rigid fan and silicon oil clutch fan. There are currently advanced electromagnetic clutch fans and electromagnetic silicon oil clutch fans.
Do not underestimate this small fan, the researchers found that the rigid connection of the cooling fan power required for 3-5% of the engine power, low-power engines even more than 10%, resulting in a very astonishing fuel consumption.
The engine manufacturers choose to install electromagnetic clutch fans and electronically controlled silicone oil fans, high-cold areas and plain high-speed vehicles, to save fuel significantly.
The second engine energy-saving measures: Intelligent speed control technology
Smart driving refers to intelligent programming to ensure that the vehicle can intelligently control the engine speed according to the operating environment. It can provide excellent fuel consumption regardless of smooth running, downhill or climbing or pumping conditions. This is like setting up a virtual trainer for each car to coach drivers on how to save fuel.
Third Engine Energy Saving Measures: Engine Parameter Matching
The loading conditions and driving conditions are very different. Although the driving conditions are various, the engine will always last for a certain period of time under a certain load and will not fluctuate drastically; the pumping conditions will not have any continuity, and the load will increase sharply when the piston pushes concrete. When the commutation changes, the load will drop rapidly and the engine needs to respond quickly to circumvent the sudden fluctuations in the speed. Therefore, the engines that match the specific parameters will no doubt save more energy than those that have not been processed.
