Dragon 850 loader fuel tank capacity?

Answer:

4, reduce the impact and vibration of the hydraulic system impact mainly occurred in the transformer, variable speed, reversing, the pipeline flow in the liquid due to the sudden closure of valve and reversing quickly of high peak pressure formed instantaneously, the connector, connector and flange looseness or sealing ring into the gap of damage caused by leakage. In order to reduce the leakage caused by shock and vibration, the following measures can be taken: first, all the tubes are fixed with a damping support so as to absorb shock and vibration energy. Adopt a reversing valve with damping, a slow switching valve, and a buffer device (such as one way throttle valve) at the end of the hydraulic cylinder. Use a low impact valve or accumulator to reduce impact. Arrange the pressure control valve properly to protect all the components of the system. Minimize the number of pipe connections, and use the welded connections as far as possible. The use of direct screw head, three joints and elbow instead of tapered pipe thread. We try to use the oil return block instead of each configuration. The maximum pressure for the specified torque used when installation bolt and plug torque, prevent the junction surface and the seal is damaged. 5, reduce the wear of dynamic seals. Most of the dynamic seals in the hydraulic system have been accurately designed. If the moving seals are machined properly, installed properly and used properly, long time no leakage can be guaranteed. From the design point of view, the following measures can be used to prolong the life of the dynamic seals. First, eliminate the radial load on the piston rod and the seal of the drive shaft. Protect the piston rod with dust ring, protective cover and rubber sleeve, prevent dust and other impurities from entering. Design and select the proper filter and easy to clean tank to prevent the accumulation of dust in the oil.
Dragon work 850 hours an hour, gas consumption is generally 14See if -17L range driver technology in the economic circumstances allow I suggest you choose the more fuel-efficient Xiagong Xiagong good quality actually lonking and the small price difference between the fuel tank, hydraulic oil tank 280L 200L
2, the sealing surface roughness due to the relative motion of the hydraulic system side surface roughness or high axial scratch will produce leakage; the roughness is too low, to a mirror when sealing lips will scrape the oil film, the oil film is difficult to form a sealing edge to produce high temperature wear, so the seal surface the roughness is not too high nor too low. With the sliding contact surface of a sealing ring with low roughness, hydraulic cylinder, valve and other dynamic seal surface roughness should be between Ra0.2~0.4 to m, to ensure that the movement of the sliding surface oil film is not destroyed. When the hydraulic cylinder, slide valve on the shaft when the axial scratches, the light can be polished sandpaper sandpaper, the weight should be plated repair. 3, reasonable design and processing sealing groove hydraulic cylinder sealing groove design or processing is good or bad, is to reduce leakage, prevent oil seal premature damage prerequisite. If the piston and piston rod static sealing groove size is too small, the sealing ring in the groove without little movement, the sealing ring at the bottom will be due to the reaction force to make it damage and lead to oil leakage. The design of the sealing groove (mainly the structure, shape, size, shape and position tolerance of the groove and the roughness of the sealing surface) shall be carried out in strict accordance with the standard requirements. To prevent the oil from static seal leakage, must be reasonable design of static seal groove dimensions and tolerances, the static seal by extrusion deformation after packing with micro concave surfaces after installation, and can seal stress higher than the sealed pressure. When the part stiffness or bolt pretension is not large enough, the mating surface will be separated under the action of the oil pressure, resulting in excessive clearance, and with the movement of the mating surface, the static seal will become a dynamic seal.
300 liters or so. Loading control machine: 1, to prevent oil leakage of the oil contamination of hydraulic pump inlet strainer should be installed, and the suction mouth from the tank at the bottom of a certain distance; should be installed at the outlet of high pressure filter, and the filtration effect should be consistent with the system requirements, to prevent dirt clogging caused by hydraulic system failure the hydraulic oil tank; partition should install the filter to remove impurities, not to go back to the oil filter filter. The hydraulic cylinder to be installed on a metal protective ring, to prevent dirt is brought into the cylinder, and can prevent water and light radiation leakage caused by erosion of the hydraulic cylinder; check and clean the internal iron impurities should be installed before the regular inspection of hydraulic components; hydraulic oil, oil deterioration, once more foam and precipitate more and oil-water separation phenomenon found immediately after cleaning and oil system. Before adding oil to the tank, the new oil should be settled by static sedimentation, and can be added before filtration. If necessary, an intermediate tank can be set up to carry out the precipitation and filtration of the new oil to ensure the cleanliness of the oil.
