【正文】 Introductionto YZ12 Vibration roller 論文178。 variable piston by electromagic valve with two oblique angle, so that the machine has four speeds, to meet the needs of different operating conditions. III. vibration of hydraulic system of vibratory hydraulic system is made up of single pump Dan Mada closed hydraulic circuit, maximum working pressure of the system is 38MPa. Vibration pump for variable inclined plate piston pump, vibration motor for quantitative inclined axis piston. By manipulating electromagic valve, you can make the vibration of pumps swashplate with opposite two variable oblique angle, so that different direction and flow of high pressure oil pump output, vibration motor with resulting different steering and speed to vibrations at different frequencies and amplitudes vibration. Four steering steering hydraulic system using opencircuit hydraulic system, the system working pressure 16MPa. By steering pump, hydraulic steering gear, two steering cylinders and tubing and other ponents. Steering pump gear pump. Five hydraulic system of hydraulic control system and accessories also include integrated control valve block, collection block, and tanks, filters, coolers, accessories. Hydraulic brake oil of systems at the same time for the braking system provides. 論文178。 Meanwhile, gearbox and rear axle brakes also promptly produce precursor braking effect. Note: in State of emergency shall not be used for emergency braking, especially in the fastrunning state. The eight section Frame Center of the frame after the frame including the former frame, articulated frame in three parts. Connecting them into a hinged support the upper structure of the machine as a whole. I. in front of the frame by the scraper before box after box before the Assembly, Board, boards, two side panels and other ponents. Its main functions are supporting vibrating wheel assembly. For the first frame structure of a typical boxes, bination of high strength steel plate, with sufficient strength and rigidity to resist strong impact force and torque of roller working. Scraper to scrape adhesion under the soil on the drum. Scraper frontend and vibrating wheel clearance of cylindrical surface can be adjusted. II. after frame after frame fuel tank, protection against roll frame, hydraulic tanks, hydraulic tank supports, panels, frames and other ponents. Its main function is to support the engine and the cab, fixed rear axle. After the frame of the structure of a rectangular box, front and Center articulated frame in vertical shaft and attached to the front plate, followed by the Assembly of the fuel tank, the middle is grooved steel frame. In order to ensure strength, weak parts of strengthening ribs to strengthen, and trough steel plate with seal sealed into a box girder structure. Rear axle at the bottom plate with bolts and rear axle Assembly of rigid connection. To reduce the effects of vibration, between the engine and rear frame with elastic damping blocks, and you can easily adjust the engine to a horizontal position. III. Centre pinned by articulated frame Center articulated frame, shaft end bezel, ball bearings and other ponents. Through it before and after the frame articulated into a whole, can swing around 論文178。譯文 15 ditch or slope, also shall not use this machine. Z travel and construction should be open before and after the lamp lighting at night. Z while working on a rainy day, in order to ensure visibility, use front and rear wiper. Z to avoid inadvertently overturned while working at the edge of the slope, not swerved. Z in the rain, you should try to avoid vibration paction jobs at the edge of the slope. Due to vibration will increase the risk of both taxi. Z roller in open cover parts for maintenance, security note head. The 12th section Transport and handling safety requirements Safety requirements for transport and handling under normal circumstances, roller not long distance at high speed. Long distance (30 km) when moving site, need towing equipment shipment. I. Transport whether it be road or railway transport, road roller selection must have the appropriate volume of transport vehicles and loading capacity. Transport, frames before and after fixed with hinged safety Rod should be connected together, and also to take the necessary measures to prevent the rollers sliding and rolling. II. handling when loading and unloading roller, loading and unloading tools must have sufficient bearing capacity. When you use a cable car loading and unloading roller, using Center articulated frame fixtures must first be fixed when using large flat hook lift, to ensure th
