The road roller is mainly composed of a diesel engine, a transmission system, a vibration wheel, a measurement and control system, and the like. The solid arrow is the original device, and the dotted arrow is the new measurement and control system. Principle of automatic frequency modulation The power transmission route of this machine is: diesel engine to clutch to belt drive to vibration wheel. By the formula f=N160=kN60 (where: f is the vibration frequency of the roller, N1 is the eccentric block (shaft) rotation speed, k is the belt transmission coefficient, N is the diesel engine rotation speed, N1=kN), it can be known that changing the diesel engine rotation speed N can change the roller Vibration frequency f.
The measurement and control system is provided with soil keys corresponding to the natural frequencies of the various soils in the introduction, when the operator presses a key corresponding to the road surface soil. When the operator presses another soil button, the vibration frequency of the roller will be automatically adjusted to the optimal frequency point corresponding to the natural frequency of various soils in the introduction to compact the road surface soil so as to achieve automatic frequency modulation.
The measurement and control system scheme design chooses the rotational speed sensor to measure the vibration frequency of the vibration wheel. The controller takes the 51 single-chip computer as the core. The soil type button is manually selected, and the center frequency is adjustable by software control. The advantage of this solution is that the measurement and control system is simple in structure, reliable in operation, wide in adaptation, easy in operation, and has no special requirements for the driver.
Conveyor Pulley
Established in 1976 in China, JUXIN, are
considered as the first Conveyor and components: roller, frame, pulley
manufacturer in Hengshui, China. The rapid growth of the business in
China soon created the need for a distribution depot, therefore in 2007 a
new branch was put in place in Tianjin City The modern day JUXIN now
manufactures conveyor products to suit all supplies of mining, steel
plant, cement plant, quarry, crushing and screening equipment. Our
expertise and knowledge allows us to deliver fully on our promises of
providing quick answers to your enquiries, rapid service, high quality
products and above all, we are fully committed to be the best at what we
do Service Agents are also located in: UK, South Africa, Kenya,
Indonesia, Thailand, Kazakhstan All products are underpinned by
unmatched customer service and prompt, reliable delivery. Our internal
quality systems are designed to ensure that all orders are handled
quickly and are manufactured to the ultimate quality standards. Several
checking processes are in place prior to orders being released from the
factory. Many tightly controlled inspections occur during the production
processed.
