混凝土自上料攪拌車(chē)，氣缸的功能是將壓縮空氣的壓力能轉(zhuǎn)換為機(jī)械能，氣缸是混凝土攪拌站中保養(yǎng)和維修時(shí)容易忽視的一部分，下面混凝土自上料攪拌車(chē)講一下氣缸產(chǎn)生的故障及維修方法：正常情況下，氣缸應(yīng)隨電磁閥電源的通斷開(kāi)關(guān)迅速到位；由于氣缸活塞反復(fù)運(yùn)動(dòng)，則對(duì)缸壁及活塞進(jìn)行潤(rùn)滑十分重要。由于氣缸裝配不當(dāng)和長(zhǎng)期使用，氣動(dòng)執(zhí)行元件（氣缸）易發(fā)生內(nèi)、外泄漏，輸出力不足和動(dòng)作不平穩(wěn)，緩沖效果不良，活塞桿和缸蓋損壞等故障現(xiàn)象。

The function of the cylinder of the concrete self loading mixer is to convert the pressure energy of the compressed air into mechanical energy. The cylinder is a part that is easy to be ignored in the maintenance and repair of the concrete mixing plant. Next, the concrete self loading mixer will talk about the faults and maintenance methods of the cylinder: under normal circumstances, the cylinder should be in place quickly with the on-off switch of the solenoid valve power supply; As the cylinder piston moves repeatedly, it is very important to lubricate the cylinder wall and piston. Due to improper assembly and long-term use of the cylinder, the pneumatic actuator (cylinder) is prone to internal and external leakage, insufficient output force and unstable action, poor cushioning effect, damage of piston rod and cylinder head and other faults.

1、氣缸出現(xiàn)內(nèi)、外泄漏，內(nèi)漏是指氣缸活塞組件磨損嚴(yán)重，造成那個(gè)活塞前后竄氣，影響氣缸動(dòng)作的快慢，嚴(yán)重時(shí)造成開(kāi)關(guān)不到位；外漏是指活塞桿與氣缸接觸的端部密封件磨損嚴(yán)重而漏氣，造成活塞桿回復(fù)速度慢，甚回復(fù)不到位。

1. The cylinder has internal and external leakage. Internal leakage refers to the serious wear of the cylinder piston assembly, resulting in the front and rear blow by of the piston, affecting the speed of the cylinder action, and causing the switch not in place when it is serious; External leakage refers to the serious wear and leakage of the end seal between the piston rod and the cylinder, resulting in the slow recovery speed of the piston rod, or even the recovery is not in place.

2、混凝土自上料攪拌車(chē)，氣缸的輸出力不足和動(dòng)作不平穩(wěn)，一般是因活塞或活塞桿被卡住、潤(rùn)滑不良、供氣量不足，或缸內(nèi)有冷凝水和雜質(zhì)等原因造成的。對(duì)檢查油霧器的工作是否可靠；供氣管路是否被堵塞。當(dāng)氣缸內(nèi)存有冷凝水和雜質(zhì)時(shí)，應(yīng)及時(shí)清理。

2. The insufficient output force and unstable action of the cylinder of the concrete self loading mixer are generally caused by the piston or piston rod being stuck, poor lubrication, insufficient air supply, or condensed water and impurities in the cylinder. Check whether the oil atomizer works reliably; Check whether the air supply pipeline is blocked. When there is condensate and impurities in the cylinder, it shall be cleaned in time.

3、混凝土自上料攪拌車(chē)，氣缸的緩沖效果不良，一般是因緩沖密封圈磨損或調(diào)節(jié)螺釘損壞所致。此時(shí)，應(yīng)更換密封圈和調(diào)節(jié)螺釘。

3. The buffer effect of the cylinder of the concrete self loading mixer is poor, which is generally caused by the wear of the buffer seal ring or the damage of the adjusting screw. At this time, replace the sealing ring and adjusting screw.

4、混凝土自上料攪拌車(chē)，氣缸的活塞桿和缸蓋損壞，一般是因活塞桿安裝偏心或緩沖機(jī)構(gòu)不起作用而造成的。對(duì)此，應(yīng)調(diào)整活塞桿的中間位置；更換緩沖密封圈或調(diào)節(jié)螺釘。

4. The damage of the piston rod and cylinder head of the cylinder of the concrete self loading mixer is generally caused by the eccentric installation of the piston rod or the failure of the buffer mechanism. In this regard, the middle position of the piston rod should be adjusted; Replace the buffer seal ring or adjusting screw.
