大型吸污车顾名思义就是体积比一般的吸污车要打一些，同时由于它的动力大和装载能力大，省去力小型吸污车来回运输的时间，所以往后大型吸污车的使用效率比普通的吸污车大的多，它可以吸更多的泥浆和淤泥，更大的石头和砖块，对于这样一个我们城市环境的守卫者，我们应该更加细心的爱护和保养，让它每天都能保持良好的工作状态，同时也可以为我们创造更多的生产价值！
Large sewage suction truck suggests that the volume ratio of the general sewage suction truck to make some at the same time, because of its large power and large load capacity, small power save sewage suction truck round-trip transportation time, so the use efficiency of large sewage suction truck later than the ordinary sewage suction truck is larger, it can absorb more mud and mud, larger stones and bricks, for such a US city environment guardians, we should be more careful care and maintenance, let it every day to maintain a good working condition, but also can create more value for our production!
关于大型吸污车平时的保养和注意事项我归纳一下几点：
On the large sewage suction car usually maintenance and attention to the matter I summed up a few points:
一、润滑油：1、真空泵用普通柴机油每3天要检查补充一次；2、液压油箱里面的液压工作油每7天要检查补充一次。
First, the lubricating oil: 1, vacuum pump with ordinary diesel oil every 3 days to check the supplement once; 2, the hydraulic oil tank inside the hydraulic oil every 7 days to check the supplement once.
二、传动机构的注意事项：工作前检查传动轴，联轴节等有无异常松动，要及时拎紧固定，否则会对泵及取力器和变速箱等装置造成不必要的损伤。
Note two: the work of the transmission mechanism, check the drive shafts, couplings and other abnormal loose, timely tightening fixed, otherwise to the pump and the power take-off and transmission device to cause unnecessary damage.
三、单向伐气水分离器（双重保护装置）：它是万一当罐内滿量自动停吸装置发生故障时，为防止污水进入泵内，而自动工作的双重保护装置。吸入污泥，则易浸蚀球座和球，故要定期更换。另外，作业时容易积存污水，所以作业结束后一定要排水和清扫浮球，并定期更换浮球。
Three, one-way gas water separator (dual protection device): it is in case when the tank full amount of automatic shutdown device failure, to prevent the sewage into the pump, and automatic work of the dual protection device. It is easy to suck sludge, and etching tee ball, it should be changed regularly. In addition, operation easy to accumulate sewage, so after the end of job must drain and clean float, and regular replacement of the floating ball.
四、油气分离器（它能分离真空泵排出的油、水、气、混合物）：分离的机油重新作为真空泵润滑油使用，但分离出的水会贮留在箱底，如油色变白，会降低润滑性和气密性。因此应定期清扫内部，更换机油，油量在真度约93千帕时补充到量油尺下中间刻线，使用普通机械油，每月清洁一次内部。
Four, oil and gas separator (it can separate the vacuum pump from the discharge of oil, water, gas, mixture): separation of the oil back as vacuum pump oil, but the separated water will be stored in the box, such as white oil, will reduce the lubrication and air tightness. It should be cleaned regularly, the replacement of oil, the amount of oil added to the middle line dipstick at true degree about 93 thousand PA, the use of ordinary mechanical oil, clean once a month inside.
五、后罐门夹紧装置：长期使用后，内部产生污垢，无法拧紧手轮，所以每隔3个月应铲除和清扫内部门边的污渍和铁锈，并适当补充润滑油。
Five, after the tank door clamping device: after long-term use, internally generated dirt, to tighten the handwheel, so every 3 months should be removed and clean inside the door of the dirt and rust, and appropriate to add lubricating oil.
六、使用取力器时，离合器一定要快踩慢放，否则会损坏变速箱和取力器.
Six, the use of force, the clutch must quickly step on the slow release, otherwise it will damage the gearbox and the power of the force.
