来源:http://www.sdzkjf.cn/ 日期:2022-06-29 发布人:zhongke
液压油泵、马达若发生故障,需及时更换下送往指定维修部维修,在拆下旧油泵、马达,装上新油泵、马达时,应注意以下几点:
If the hydraulic oil pump and motor fail, they shall be replaced in time and sent to the designated professional maintenance department for maintenance. When removing the old oil pump and motor and installing the new oil pump and motor, the following points shall be noted:
拆下旧油泵、马达时,应先拆下油管,须将油泵和油管上的各个油口立即密封,防止灰尘进入油泵及油管内,然后再将油泵从搅拌车上拆下;
When removing the old oil pump and motor, the oil pipe shall be removed first, and all oil ports on the oil pump and oil pipe shall be immediately sealed to prevent dust from entering the oil pump and oil pipe, and then the oil pump shall be removed from the mixer truck;
平稳地装上油泵、马达,注意装配的对中良好,螺栓拧紧,启封油泵、马达油口,接上油管。
Install the oil pump and motor stably, pay attention to the good alignment of the assembly, tighten the bolts, unseal the oil port of the oil pump and motor, and connect the oil pipe.
所有油管安装完毕后,加注液压油至规定的油位,并排空系统内的空气;
After all oil pipes are installed, fill the hydraulic oil to the specified oil level and drain the air in the system;
检查油箱油位,若不到位,需加入清洁液压油到位;
Check the oil level of the oil tank. If it is not in place, add clean hydraulic oil in place;
启动汽车发动机,怠速运行10分钟(油泵在空挡位置,搅拌筒不动的情况下),检查油泵、马达噪音情况及各油管是否有漏油现象;
Start the automobile engine and run it at idle speed for 10 minutes (when the oil pump is in neutral position and the mixing drum does not move), check the noise of the oil pump and motor and whether there is oil leakage in each oil pipe;
搅拌车旧油泵、电机拆装时,应先拆下油管,并立即密封油泵和油管上的油口,防止灰尘进入油泵和油管,然后应将油泵从搅拌车上拆下。
When disassembling the old oil pump and motor of the mixer truck, the oil pipe shall be removed first, and the oil port on the oil pump and oil pipe shall be immediately sealed to prevent dust from entering the oil pump and oil pipe, and then the oil pump shall be removed from the mixer truck.
顺利安装油泵和电机。注意:拧紧螺钉,密封油泵、电机、油口和连接管。
Install the oil pump and motor smoothly. Note: tighten the screws to seal the oil pump, motor, oil port and connecting pipe.
所有油管安装完毕后,拧下油泵R口油塞,将泵内空气排尽,再拧紧R口油塞,直到从R口流出的油中不含气体.
After all oil pipes are installed, unscrew the oil plug at the R port of the oil pump, exhaust the air in the pump, and then tighten the oil plug at the R port until the oil flowing from the R port contains no gas
水泥自动搅拌车
拆下电机,从顶部T油口接头向电机中加入干净的液压油,直至注满,然后拧紧管接头。
Remove the motor, fill the motor with clean hydraulic oil from the top T-port connector until it is full, and then tighten the pipe connector.
检查搅拌车油箱油位。如果不在液位中间以上,则必须就地加入干净的液压油。
Check the oil level in the oil tank of the mixer truck. If it is not above the middle of the liquid level, clean hydraulic oil must be added locally.
启动发动机,怠速怠速10分钟(控制箱两个手柄都在中间位置,搅拌筒不动),检查油泵、电机的噪音,是否有各油管漏油。
Start the engine, idle for 10 minutes (both handles of the control box are in the middle position, and the mixing drum does not move), check the noise of the oil pump and motor, and check whether there is oil leakage from each oil pipe.
缓慢操作操纵杆,使搅拌筒在一个方向较慢的进料方向转动20分钟(搅拌筒内无物料,小车怠速);
Slowly operate the control lever to make the mixing drum rotate in a slower feeding direction for 20 minutes (there is no material in the mixing drum, and the trolley is idling);
水泥自动搅拌车操纵杆回位至中间位置停止搅拌筒,检查油箱油位,加油至中间位置。
Return the control lever of the automatic cement mixer to the middle position to stop the mixing drum, check the oil level in the oil tank, and add oil to the middle position.
