液压统使用前要主要哪些事项？
1、使用者把握液压系统的工作原理，认识各种控制机构的操纵特点和调整手柄的位置、旋向等。
2、开车前检查油面，保证液压系统有足够的油液。按期检查更换液压油液，新设备使用三个月左右即应清洗油箱，更换油液，以后每隔半年至一年进行清洗和换油一次。加油时要过滤。
3、油箱应加盖密封，油箱上面的通气孔处设置空气滤清器。
4、液压系统中根据需要配置粗、精过滤器，并常常检查、清洗和更换。
5、开车前应检查各调整手柄、手轮的位置是否准确，电气开关和行程开关的位置是否正常，主机上工具的安装是否准确、牢固等，再对导轨和活塞杆外露部门进行擦拭，然后方可开车。
6、开车时，有专用控制油路液压泵的，要先启动该泵，再启动主液压泵。
7、当环境温度较低、油液黏度较大时，应想法升高油温。例如，采用点动方式反复启动定量泵；减小变量泵斜盘倾角，启动后空转一段时间等。
8、有排气装置的液压系统应进行排气，无排气装置的液压系统应先空载往复运动多次，使之天然排出气体。
9、对压力控制元件的调整，一般首先从溢流阀开始，使整个液压系统的压力从零逐步进步，终极达到划定压力值，然后依次调整各回路的压力控制阀。
10、流量控制阀的调整，应使流量从小到大，逐步调整。同步运动执行元件的流量控制阀应同时调整。要保证运动平稳性。
11、工作中应随时留意油液温升，正常工作时，油箱中油液温度应不超过60℃。
12、设备若长期不用，应将各手轮全部放松，以防弹簧产生永久变形而影响元件机能。

Before using the main hydraulic system to what matters ?
A user to grasp the hydraulic system works , understanding the manipulation of a variety of features and control mechanism to adjust the handle position , rotation, and so on. 2 , check the oil level before driving to ensure that there is enough oil in the hydraulic system . Regularly check and replace the hydraulic fluid , new equipment for three months or so that the tank should be cleaned , replace the oil after every six months to a year for cleaning and oil change once. To filter when refueling . 3 , the fuel tank should be affixed to the seal tank vent above set at the air filter. 4 , the hydraulic system needs to be configured according to coarse , fine filter , and often inspection, cleaning and replacement. 5, the car should be checked before each adjustment handle, hand wheel position is accurate, electrical switches and limit switch position is normal, whether the tools are installed on the host accurate , solid , etc. , and then exposed to the rail sector and the piston rod to wipe , and then before driving. 6 , when driving , a dedicated control circuit of the hydraulic pump , first start the pump , and then start the main hydraulic pump . 7 , when the ambient temperature is low , the oil viscosity is large, elevated oil temperature should be thinking . For example , using the jog mode starts repeated dosing pumps ; reduced variable pump swash plate angle , starts idling period of time. 8 , an exhaust system of the hydraulic system should be vented , no exhaust load of the hydraulic system should be reciprocated repeatedly , so that the natural exhaust gases. 9 , the adjustment of the pressure control element , generally the first starting from the relief valve , the pressure of the hydraulic system gradually progress from zero , the final pressure value reaches delineated , and each circuit in order to adjust the pressure control valve . 10 , the flow control valve adjustment , should the flow from small to large , and gradually adjust . Synchronous movement of the flow control valve actuator should also be adjusted. To ensure smooth movement . 11 , work should always pay attention to the oil temperature, normal working hours, the tank fluid temperature should not exceed 60 ℃. 12 , the device if the long-term need , should all relax the hand wheel to prevent permanent deformation of the spring elements affecting performance .
