確定油路暢通,柴油機供給系統沒有空氣后,可拆開油泵蓋板,板動操縱手柄,撥動油泵拉桿,看拉桿是否靈活和柱塞彈簧是否斷裂。在自動上料混凝土攪拌車拉桿靈活和柱塞彈簧沒斷的情況下,可啟動柴油機中速運轉10分鐘,還有斷火現象時,可用一只銅榔頭輕輕敲擊輸油泵大螺帽,一邊敲一邊聽柴油機聲音,如果聲音不正常,說明輸油泵活塞和推桿發卡,進行修理或更換。
After confirming that the oil circuit is unblocked and there is no air in the diesel engine supply system, the cover plate of the oil pump can be removed, the operating handle can be moved, and the pull rod of the oil pump can be pulled to see whether the pull rod is flexible and whether the plunger spring is broken. Under the condition that the pull rod of the automatic feeding concrete mixer is flexible and the plunger spring is not broken, the diesel engine can be started to run at a moderate speed for 10 minutes. If the fire is still broken, a copper hammer can be used to gently tap the large nut of the fuel transfer pump, while listening to the sound of the diesel engine. If the sound is abnormal, it means that the piston and push rod of the fuel transfer pump are jammed for repair or replacement.
拆下噴油器總成,轉動曲軸數圈,即有水噴出,說明缸蓋,缸體有裂紋或砂眼,遇到這種情況時,可向用戶解釋或向自動上料攪拌車公司反映。低壓油流暢通后,可用手壓泵排除油路中的空氣,打開泵頭放氣螺釘,直到沒有氣泡時,方可上緊放氣螺釘。
Remove the fuel injector assembly, rotate the crankshaft for several cycles, and water sprays out, indicating that the cylinder head and cylinder block have cracks or sand holes. In this case, you can explain to the user or report to the automatic feeding mixer company. After the low pressure oil flow is unblocked, the air in the oil circuit can be removed by the hand pump, and the air release screw of the pump head can be opened until there is no bubble, then the air release screw can be tightened.
油嘴不霧化,油泵柱塞彈簧和彈簧座斷裂,卡死不工作,或是柴油內有水。拆下油嘴總成檢查開啟壓力和霧化,如果油嘴總成正常,可讓用戶用干凈柴油裝入壺中用油路旁接法進行試驗。打開自動上料攪拌車油箱開關,拆下輸油泵進油管,看油流情況,如果油流很快,說明正常,如果油流時斷時續查油路。
The nozzle does not atomize, the plunger spring and spring seat of the oil pump are broken, stuck and do not work, or there is water in the diesel. Remove the nozzle assembly to check the opening pressure and atomization. If the nozzle assembly is normal, the user can use clean diesel oil to load it into a pot and use the oil circuit side connection method to test. Turn on the oil tank switch of the automatic feeding mixer truck, remove the oil inlet pipe of the oil transfer pump, and check the oil flow. If the oil flow is fast, it indicates that it is normal. If the oil flow is intermittent, check the oil circuit.
自動上料攪拌車的正確操作方法步驟
Correct operation steps of automatic feeding mixer
自動上料攪拌車柔性正確操作方法可以歸納為:一輕、二穩、三離、四勤、五協調、六嚴禁。
The correct flexible operation methods of the automatic feeding mixer can be summarized as follows: one light, two stable, three separated, four diligent, five coordinated and six forbidden.
一輕:在自動上料攪拌車作業時腳跟緊抵駕駛室地板,腳板和油門踏板保持平行,輕緩地下壓加油踏板。
One light: during the operation of the automatic feeding mixer, the heel is firmly against the cab floor, the foot plate is parallel to the accelerator pedal, and gently press the fuel pedal.
二穩:自動上料攪拌車在作業中,油門始終要穩住。一般作業狀態下,油門開度在70%左右為宜。
Second stability: During the operation of the automatic feeding mixer, the accelerator should always be stable. In general operation state, the throttle opening should be about 70%.
三離:在自動上料攪拌車作業時,腳板應和制動踏板分離開,平放到駕駛室地板上,決不能踩在制動踏板上。自動上料攪拌車常常在凹凸不平的工地作業,如果腳總是踩在制動踏板上,機身上下竄動會造成駕駛員不輕意地踩制動踏板。一般情況下,要用控制油門減速的辦法控制機況和換擋。這樣既避免了頻繁制動造成制動系統過熱,又為自動上料攪拌車快捷的提速帶來方便。
Three separations: During the operation of the automatic feeding mixer, the foot plate shall be separated from the brake pedal, and placed flat on the cab floor. Never step on the brake pedal. The automatic feeding mixer often works on uneven construction sites. If the foot always steps on the brake pedal, the body will move up and down, causing the driver to step on the brake pedal carelessly. In general, the engine condition and gear shifting shall be controlled by controlling the throttle deceleration. This not only avoids overheating of the braking system caused by frequent braking, but also brings convenience for fast speed increase of the automatic feeding mixer.
四勤:在自動上料攪拌車作業時,特別是在鏟挖作業時,應在油門穩定情況下,用循環扳動起升和轉斗操縱桿的方法使鏟斗鏟滿物料。起升和轉斗操縱杠的循環扳動就是所說的“勤”。這個過程非常重要,對耗油量的影響很大。
Fourth, during the operation of the automatic feeding mixer, especially during the shoveling operation, the bucket shall be filled with materials by cyclically pulling the lifting and bucket turning control levers under the condition that the accelerator is stable. The cyclic pulling of the lifting and bucket turning control levers is called "diligence". This process is very important and has a great impact on fuel consumption.
五協調:協調就是起升和轉斗操縱杠配合。自動上料攪拌車一般的鏟挖過程首先是將鏟斗平放在地面,平穩地駛向料堆。在鏟斗平行鏟往料堆遇阻力時,首先應遵循先起臂后收斗的原則。這樣可以更好地避免鏟斗底部受到阻力,從而能夠充分發揮大的掘起力。
Five coordination: coordination refers to the coordination of lifting and bucket control lever. The general shovel digging process of the automatic loading mixer is to place the bucket flat on the ground and drive steadily to the material pile. When the bucket is parallel to the material pile and encounters resistance, the principle of lifting the boom first and then retracting the bucket shall be followed. In this way, the bucket bottom can be better protected from resistance, so as to give full play to the large digging force.
六嚴禁:首先是嚴禁輪胎打滑。自動上料攪拌車作業時,遇阻力而猛加油門往往會出現輪胎打滑的現象。這種現象通常是由于駕駛員操作不當造成的,既增加了油耗又損傷了輪胎。其次是嚴禁后輪翹起。由于自動上料攪拌車的掘起力大,駕駛員通常在鏟挖堅實的原土和石料山等作業過程中,如果操作不當就容易出現兩后輪翹起離地現象。這種翹起動作的落地慣性,會造成鏟斗的刃板斷裂、鏟斗變形;后輪翹起很高時還容易引起前后機架等結構的焊接處開裂,甚至板材斷裂等。第三是嚴禁撞擊料堆。鏟挖普通物料,自動上料攪拌車可以用II檔作業,嚴禁以II檔以上的檔位向料堆進行慣性沖擊。正確的方法應該是鏟斗在接近料堆時適時地把檔位轉換為I檔完成一個鏟料過程。
VI. Prohibitions: First of all, tire skidding is strictly prohibited. During the operation of the automatic feeding mixer, when encountering resistance, the fuel valve will often slip. This phenomenon is usually caused by the driver's improper operation, which increases fuel consumption and damages the tire. Secondly, it is forbidden to tilt the rear wheel. Due to the large digging force of the automatic feeding mixer, the driver is usually prone to the phenomenon of two rear wheels tilting off the ground if he/she does not operate properly in the process of digging solid original soil and stone hill. The landing inertia of the lifting action will cause the blade of the bucket to break and the bucket to deform; When the rear wheel is cocked up very high, it is also easy to cause cracks at the welding points of the front and rear frames and other structures, or even plate fractures. Third, it is strictly prohibited to impact the material pile. For shoveling and digging ordinary materials, the automatic feeding mixer can operate with gear II. Inertial impact to the material pile with gear above gear II is strictly prohibited. The correct method should be to change the gear to gear I timely when the bucket is approaching the pile to complete a shoveling process.
