for mechanical construction enterprises, the technology of construction machinery has a direct influence on production of an enterprise. that is to say, choosing hydraulic motor for the goods are not as simple as people normally thought it is. it demands that company understand deeply their produce pg电子下载-pg电子游戏 piston motor,hydraulic winch,gearbox,hydraulic steering unit,axial piston motor products and scale to get suitable ones.if the technology is in a healthy state, it can promote the production. if the technology is in a poor state, it can hinder the production. for the engineering machine driven by the hydraulic device, the normal operation of fluid system is a main indicator. the qualified hydraulic oil is the guarantee for the reliable operation of hydraulic system. the correct maintenance is the foundation for the normal operation of this system. for this purpose, the author will try to discuss the methods about how to maintain fluid system according to work practice.
first, choose the suitable hydraulic oil. this oil plays an important role in this system. it has the following functions, such as pressure transmission, lubrication, cooling and sealing. if this oil is not selected rightly, the durability of hydraulic system will be influenced. besides, different hydraulic oils can not be mixed. or else, the property of this oil will be changed and thus it will influence this system. meanwhile, the smelly oil cannot be used.
second, stop impurities entering the hydraulic system. the clean hydraulic oil is the guarantee of hydraulic system. if the impurities enter this system, some precise couples will be blocked and thus the operation will be influenced. here the author will introduce some ways about how to stop impurities entering the system. first, the oil should be filtered. people can not remove the filter just in order to fill the oil up quickly. second, the tool used to add oil must be clean. third, before people dismantle the fuel tank, they must completely clean the fuel tank. fourth, the fluid system should be cleaned for many times. the hydraulic elements and rubber tube should be cleaned carefully. in addition, people should remember to dry them by high-pressure blast.
last but not least, stop air entering hydraulic system. in the normal situation, there is air in the hydraulic oil. when the pressure is reduced, the air dissociates from the oil and then the air bubble corrodes hydraulic elements. as a result, the operation of hydraulic system becomes unstable and the working efficiency is quite low. through the following ways people can prevent the air entering the system. firstly, people should often eliminate the air in the system after changing oil. secondly, the oil pipeline should be sealed well.
