Excavators job Notes 1, pay attention to cavitation and noise overflow work should always pay attention to the voice of the pump and pressure relief valve, how much money if you pump a "cavitation" noise Wheeled excavators, through the exhaust after can not be eliminated should be identified and can be used after the reasons for troubleshooting. If an actuator load slowly in the absence of action, accompanied by the sound of the relief valve overflow, should immediately downtime. 2, hydraulic pressure and fuel tank-type tank control pressure at work should always pay attention to the pressure tank, the pressure must be maintained within a range of random "manual" provisions. Pressure is too low, insufficient pump inlet fragile, the pressure is too high, the hydraulic system leak, likely to cause low pressure oil pipe explosion. After equipment maintenance and oil change after the system drained of air small wheeled excavators prices, according to a random check the oil level state "manual" provisions, the machine stopped on a flat place, turn off the engine 15min again Check the oil level, supplemented if necessary. 3. Other considerations job to prevent flying stones against hydraulic cylinders, piston rods, hydraulic tubing and other parts. If you click on the piston rod has a small injury, a timely oil stone will rub off dots around the edges to prevent damage to the piston rod seals, can continue to be used without oil leakage. 24h continuous shutdown in more than one device, before starting, the fuel injection pump To prevent damage to the hydraulic pump dry grinding.泰安嘉 and Heavy Machinery Engineering Co., mechanical engineering methods engine vibration control engineering machinery engine vibration resonance sometimes can not be avoided, therefore, used to increase the system damping or dynamic vibration absorber to reduce vibration response. Dynamic Absorber belong pressing band control, using viscoelastic damping material has a high energy loss, when the vibration damping material spread in the interior of the material tensile, bending, shear deformation, which consume large amounts of vibrational energy used round excavators, the vibration damping. The main advantage of using vibration damping technology is not necessary to change the original structure, no additional auxiliary equipment, requires no external energy, take up less space efficient, is a promising vibration and noise reduction measures. Loader pioneered this dynamic vibration damper in the selection, use of new technologies to achieve the desired effect of vibration and noise reduction. Conclusion As people improve the mechanical properties of engineering requirements, traditional vibration reduction technology can not meet the requirements, the introduction of new damping technology is imperative. In the future, to continue the application of modern design methods and tools, the use of advanced manufacturing technology to reduce or eliminate harmful engine excitation forces and moments generated during operation of the control and effective, reasonable cost of construction machinery engine damping system full play action to reduce the impact of construction machinery engine vibration performance and improve our products in the market competitiveness.泰安嘉 and Heavy Machinery Co., Ltd.
