大型吸污車顧名思義就是體積比一般的吸污車要打一些，同時由于它的動力大和裝載能力大，省去力小型吸污車來回運輸的時間，所以往后大型吸污車的使用效率比普通的吸污車大的多，它可以吸更多的泥漿和淤泥，更大的石頭和磚塊，對于這樣一個我們城市環境的守衛者，我們應該更加細心的愛護和保養，讓它每天都能保持良好的工作狀態，同時也可以為我們創造更多的生產價值！
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!
關于大型吸污車平時的保養和注意事項我歸納一下幾點：
On the large sewage suction car usually maintenance and attention to the matter I summed up a few points:
一、潤滑油：1、真空泵用普通柴機油每3天要檢查補充一次；2、液壓油箱里面的液壓工作油每7天要檢查補充一次。
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、傳動機構的注意事項：工作前檢查傳動軸，聯軸節等有無異常松動，要及時拎緊固定，否則會對泵及取力器和變速箱等裝置造成不必要的損傷。
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、單向伐氣水分離器（雙重保護裝置）：它是萬一當罐內滿量自動停吸裝置發生故障時，為防止污水進入泵內，而自動工作的雙重保護裝置。吸入污泥，則易浸蝕球座和球，故要定期更換。另外，作業時容易積存污水，所以作業結束后一定要排水和清掃浮球，并定期更換浮球。
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、油氣分離器（它能分離真空泵排出的油、水、氣、混合物）：分離的機油重新作為真空泵潤滑油使用，但分離出的水會貯留在箱底，如油色變白，會降低潤滑性和氣密性。因此應定期清掃內部，更換機油，油量在真度約93千帕時補充到量油尺下中間刻線，使用普通機械油，每月清潔一次內部。
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、后罐門夾緊裝置：長期使用后，內部產生污垢，無法擰緊手輪，所以每隔3個月應鏟除和清掃內部門邊的污漬和鐵銹，并適當補充潤滑油。
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、使用取力器時，離合器一定要快踩慢放，否則會損壞變速箱和取力器.
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.
