Small single drum vibrating roller, mechanical hydraulic single drum compactor, DL550 single drum compactor business is the responsibility of the creators, users and transforming those resources DL550 single drum rollers, who is also the producer and the emission of pollutants. Enterprises should conform to predict the development trend of history and the spirit of the country, the nation, the mechanical hydraulic single drum compactor for future generations and responsible attitude, enhance resource conservation and environmental protection. Promote the construction of ecological civilization, to better fulfill their social responsibilities. So, companies should do it? Strict compliance with the conservation of resources, promote the progress of energy saving technologies, the development of circular economy. First, the structural characteristics: When the device is in a state of vibration, the engine speed is constant; hydraulic system uses variable displacement pump and fixed motor integrated structure, composed of a closed-loop, high volumetric efficiency; the rotation direction of the motor by two-way variable pump control, output by changing the speed of the pump displacement is achieved; the volume of the system pump and motor is small, the whole structure is arranged more mobility; with a water spray system, easy to operate valves, pipes can be easily removed for cleaning and replacement ; joystick can be adjusted according to the different needs of different angles; aircraft are small, simple, easy to transport Second, the technical parameters: Rated power (kW) 3.3 work quality (kg) 560 Working speed (km / h) 0- 3.6 Theoretical gradeability, vibration on / off (%) 30/35 frequency (Hz) 55 Exciting force (kN) 15 Nominal amplitude (mm) 0.35 vibration wheel width (mm) 550
