概述：經(jīng)計算分析，活塞桿彎曲的原因是動臂油缸的兩端與車架和動臂一起傾斜，支撐寬度過小，表明裝配調(diào)整間隙不合適或裝配間隙過大。側面磨損嚴重
經(jīng)計算分析，活塞桿彎曲的原因是動臂油缸的兩端與車架和動臂一起傾斜，支撐寬度過小，表明裝配調(diào)整間隙不合適或裝配間隙過大。側面磨損嚴重，應增加支撐寬度；沉積物在缸體下端的積累和動臂缸下端的磨損表明，沉積物大量積累且旋轉摩擦較大。
Through calculation and analysis, the reason for the bending of the piston rod is that both ends of the boom cylinder are inclined with the frame and boom, and the support width is too small, indicating that the assembly adjustment clearance is inappropriate or the assembly clearance is too large. If the side is seriously worn, the support width shall be increased; The accumulation of deposits at the lower end of the cylinder block and the wear at the lower end of the boom cylinder show that there is a large accumulation of deposits and large rotational friction.
改進包括：
Improvements include:
1.增加支撐寬度，一般的支撐寬度是活塞桿直徑的1.21.5倍。
1. Increase the support width. The general support width is 1.2 to 1.5 times the diameter of the piston rod.
2.在組裝過程中，請充分利用調(diào)節(jié)墊，以確保動臂油缸兩端與機架和動臂之間的間隙和對齊，并提高調(diào)節(jié)墊材料的耐磨性。
2. During assembly, please make full use of the adjusting pad to ensure the clearance and alignment between the two ends of the boom cylinder and the frame and boom, and improve the wear resistance of the adjusting pad material.
3.完善排放結構；增加開孔距離H1和出料板的傾斜角度α，減少毛坯的堆積，有利于物料的順利出料；增加動臂油缸下端對主機的排放。距離H2是為了便于大型石材的排出。
3. Improve the emission structure; Increase the opening distance H1 and the inclination angle of the discharge plate α， Reduce the accumulation of blanks, which is conducive to the smooth discharge of materials; Increase the discharge of the lower end of the boom cylinder to the main engine. The distance H2 is to facilitate the discharge of large stones.
4.說明手冊規(guī)定了定期積聚的物料的要求。改進后，活塞桿不再彎曲。
4. The instruction manual specifies the requirements for periodic removal of accumulated materials. After improvement, the piston rod is no longer bent.
魯樽自動上料攪拌車發(fā)動機水溫過高
The engine water temperature of Lutun automatic feeding mixer is too high
1.魯樽自動上料攪拌車在普通道路上使發(fā)動機過熱。它應盡快降低速度，將汽車開到樹蔭下，或開到相對涼爽的地方停下汽車，但不要急于熄火。
1. The engine of Lutun automatic feeding mixer truck overheats on ordinary roads. It should reduce the speed as soon as possible, drive the car to the shade of trees, or drive to a relatively cool place to stop the car, but don't rush to stop the engine.
2.打開機蓋，讓發(fā)動機以怠速運行，等待發(fā)動機溫度逐漸恢復正常。發(fā)動機水溫恢復正常后，關閉發(fā)動機。然后等待一會兒，直到發(fā)動機的水溫充分下降，然后檢查發(fā)動機的冷卻水量。
2. Open the engine cover, let the engine run at idle speed, and wait for the engine temperature to gradually return to normal. When the engine water temperature returns to normal, turn off the engine. Then wait for a while until the water temperature of the engine drops sufficiently, and then check the cooling water volume of the engine.
3.此時，魯樽自動上料攪拌車發(fā)動機的冷卻水量可能嚴重不足。按照規(guī)定的量補充冷卻水后，檢查冷卻系統(tǒng)以確保沒有其他故障，您可以啟動發(fā)動機并繼續(xù)行駛。還要檢查水箱百葉窗是否被異物堵塞，風扇葉片的工作狀況，發(fā)動機皮帶是否打滑以及發(fā)動機水泵的運行。
3. At this time, the cooling water of the engine of Lutun automatic feeding mixer may be seriously insufficient. After replenishing the cooling water according to the specified amount, check the cooling system to ensure that there are no other faults. You can start the engine and continue driving. Also check whether the shutter of the water tank is blocked by foreign matters, the working condition of the fan blade, whether the engine belt slips and the operation of the engine water pump.
