裝載機是施工過程中不可缺少的一個設備，所以平常要好好維護它，防止出現問題而造成隱患，那么我們在這里了解下一個問題--裝載機氣缸套拉傷以及磨損的原因措施。

The loader is an indispensable equipment in the construction process, so it should be well maintained to prevent problems from causing hidden dangers. Here we learn about the next problem -- the causes and measures of the tension and wear of the loader cylinder liner.

裝載機缸套應變

Loader cylinder liner strain

缸套應變的主要表現是：缸內活塞發(fā)出敲擊聲；柴油機功率下降；油燃燒，尾氣呈藍色或白色；油變稀，壓力下降。

The main manifestations of cylinder liner strain are: the piston in the cylinder makes a knocking sound; Diesel engine power decreases; When the oil burns, the tail gas is blue or white; The oil becomes thinner and the pressure drops.

(1) The causes of cylinder failure are:

①冷卻系統(tǒng)故障，機器過熱，活塞受熱膨脹過大；

① The cooling system is faulty, the machine is overheated, and the piston is heated and expanded too much;

②機油量不足、變質或含有雜質，造成潤滑不良；

② Insufficient oil, deterioration or impurities, resulting in poor lubrication;

③活塞與缸壁間隙過?。ǘ嘁娪谛聶C或剛大修的柴油機）

③ The clearance between piston and cylinder wall is too small (mostly seen in new engines or diesel engines that have just been overhauled)

④活塞環(huán)斷裂或卡??；

④ The piston ring is broken or stuck;

⑤活塞銷彈性擋圈失效，導致活塞銷移動。

⑤ The piston pin circlip fails, causing the piston pin to move.

裝載機缸套磨損

Wear of loader cylinder liner

為減少缸套磨損，除在設計制造上采取防腐耐磨措施外，在使用和維護工程中還應注意以下幾點：

In order to reduce the wear of cylinder liner, in addition to taking anti-corrosion and wear-resistant measures in design and manufacture, the following points should also be paid attention to in use and maintenance engineering:

⑴正確啟動和啟動。

(1) correct startup and startup.

冷車啟動后，應在小油門狀態(tài)下暖車3～5分鐘，方可啟動自行車。

After the cold start, the bike should be warmed up for 3 ~ 5 minutes under the condition of low throttle before starting.

帶負荷工作一段時間，待溫度升高后再進行重負荷工作。

Work under load for a period of time, and then work under heavy load after the temperature rises.

(2)保持發(fā)動機的正常溫度。

(2) Maintain the normal temperature of the engine.

柴油機溫度過低，不能保持良好的潤滑，會增加氣缸壁的摩擦力；溫度過高會降低氣缸的強度，加劇磨損。為80℃～90℃。當溫度超過95℃時，應減少負載或停機冷卻。

The temperature of the diesel engine is too low to maintain good lubrication, which will increase the friction of the cylinder wall; Too high temperature will reduce the strength of the cylinder and intensify wear. 80 ℃ ~ 90 ℃. When the temperature exceeds 95 ℃, reduce the load or shut down for cooling.

⑶保持良好的潤滑。

(3) keep good lubrication.

定期檢查并保持油品質量好，油位適中，并根據季節(jié)定期更換。使用粘度適當的油，以確保良好的潤滑。

Regularly check and keep the oil quality good and the oil level moderate, and replace it regularly according to the season. Use oil with proper viscosity to ensure good lubrication.

⑷加強三濾（空濾、機油濾、柴油濾）的保養(yǎng)。

(4) strengthen the maintenance of three filters (air filter, oil filter and diesel filter).

這是防止機械雜質進入汽缸，減少汽缸壁磨損，延長發(fā)動機使用壽命的主要措施，這對裝載機上使用的柴油機來說尤其重要，因為裝載機的含塵量往往很高。

This is the main measure to prevent mechanical impurities from entering the cylinder, reduce cylinder wall wear and prolong the service life of the engine, which is particularly important for the diesel engine used on the loader, because the dust content of the loader is often very high.

⑸提高維修保養(yǎng)質量。

(5) improve the quality of maintenance.

濟南裝載機租賃人員提醒您要嚴格按照柴油機操作和保養(yǎng)手冊規(guī)定的技術標準進行保養(yǎng)和維修作業(yè)。調整和控制各配合間隙（開啟間隙），防止因維修保養(yǎng)不當導致活塞與缸壁加速磨損。

Jinan loader leasing personnel remind you to carry out maintenance and repair operations in strict accordance with the technical standards specified in the diesel engine operation and maintenance manual. Adjust and control the fitting clearance (opening clearance) to prevent accelerated wear of piston and cylinder wall due to improper maintenance.
