Maintenance of hydraulic cylinder of loader accessories, i.e. maintenance of hydraulic medium and hydraulic cylinder block. The advantages of hydraulic transmission are simple structure, stable quality, high mechanical efficiency and easy automation. How to make the hydraulic machinery run better, correctly select the hydraulic oil according to the system pressure, running speed, working oil volume and ambient temperature, and correctly use and maintain the Jinan loader is the key to the work. When maintaining the hydraulic cylinder, be sure to prevent contamination and impurities from mixing into the hydraulic oil:

1、油缸在使用過程中應(yīng)定期更換液壓油，清洗系統(tǒng)濾網(wǎng)，保證清潔度，延長使用壽命。

1. During the use of the oil cylinder, the hydraulic oil shall be replaced regularly, and the system filter screen shall be cleaned to ensure cleanliness and prolong the service life.

2、油缸在每次使用時(shí)，要進(jìn)行全伸全縮的試運(yùn)轉(zhuǎn)5個(gè)行程然后再帶載運(yùn)行。這樣做可以排盡系統(tǒng)中的空氣，預(yù)熱各系統(tǒng)，能夠避免系統(tǒng)中存在空氣或水，在油缸缸體造成氣體爆炸（或焦燒）現(xiàn)象，這樣會(huì)損害密封件，造成油缸內(nèi)泄等故障。

2. When the oil cylinder is used each time, the test run of full extension and full contraction shall be carried out for 5 strokes, and then the loaded operation shall be carried out. This can exhaust the air in the system and preheat each system, so as to avoid the existence of air or water in the system and cause gas explosion (or scorching) in the cylinder block, which will damage the seals and cause internal leakage of the cylinder.

3、控制好系統(tǒng)溫度，油溫過高會(huì)減少密封件的使用壽命，長期油溫高使密封件發(fā)生變形，甚完全失效。

3. Control the system temperature well. If the oil temperature is too high, the service life of the seal will be reduced. Long term high oil temperature will deform the seal or even completely fail.

4、防護(hù)好活塞桿外表面，防止磕碰和劃傷對密封件的損傷，經(jīng)常清理油缸動(dòng)密封防塵圈部位和裸露的活塞桿上的泥沙，防止粘在活塞桿表面上的不易清理的污物進(jìn)入油缸內(nèi)部損傷活塞、缸筒或密封件。

4. Protect the outer surface of the piston rod to prevent the damage to the seal caused by collision and scratch. Regularly clean the sediment on the dynamic seal dust ring of the oil cylinder and the exposed piston rod to prevent the dirt on the surface of the piston rod from entering the oil cylinder and damaging the piston, cylinder barrel or seal.

5、經(jīng)常檢查各螺紋、螺栓等連接部位，發(fā)現(xiàn)松動(dòng)立即緊固好。

5. Regularly check the connecting parts such as threads and bolts, and fasten them immediately if they are loose.

6、經(jīng)常潤滑聯(lián)接部位，防止無油狀態(tài)下銹蝕或非正常磨。

6. Frequently lubricate the connecting parts to prevent corrosion or abnormal wear without oil.

因?yàn)槭墉h(huán)境溫度的影響，小型裝載時(shí)機(jī)面對很多艱難，如整機(jī)的“心臟”部件柴油機(jī)，因?yàn)闇囟鹊脑黾邮构饣偷恼扯认陆担饣陆?，并且使?dòng)力下降，其內(nèi)部機(jī)件通常也簡單發(fā)生磨損，這是對比多見的毛病。因而在搞好小型裝載機(jī)夏日保護(hù)技能的時(shí)分更要細(xì)心對柴油機(jī)進(jìn)行必要的全部的保護(hù)。

Due to the influence of ambient temperature, the small loading time is faced with many difficulties. For example, the "heart" component of the whole machine, diesel engine, because the increase of temperature reduces the viscosity and smoothness of smooth oil, and reduces the power. Its internal parts are usually simply worn, which is a common problem. Therefore, when doing a good job in the summer protection skills of small loaders, we should carefully protect the diesel engine.

為了確保小型裝載機(jī)的冷卻體系效能良好，在進(jìn)入夏日曾經(jīng)，應(yīng)對冷卻體系的各個(gè)部件進(jìn)行完全的整理、緊固和光滑，盡可能的整理冷卻體系水垢包含散熱器內(nèi)的水垢整理潔凈），以進(jìn)步散熱效能，堅(jiān)持冷卻體系冷卻水的循環(huán)。

In order to ensure the good efficiency of the cooling system of the small loader, all components of the cooling system should be completely sorted, fastened and smooth in summer, and the scale of the cooling system (including the scale in the radiator) should be sorted as much as possible, so as to improve the heat dissipation efficiency and adhere to the circulation of cooling water in the cooling system.

查看水泵一電扇傳動(dòng)皮帶，皮帶經(jīng)長期使用后，皮帶會(huì)發(fā)生疲憊、變形，下降冷卻作用。皮帶更換時(shí)，要留意類型和長度，并準(zhǔn)確調(diào)整其松緊度。

Check the drive belt of water pump and electric fan. After long-term use, the belt will be tired and deformed, reducing the cooling effect. When replacing the belt, pay attention to the type and length, and accurately adjust its tightness.

查看水箱銜接膠管，水箱的膠管的耐油性對比差，簡單早期損壞，然后影響供水量，導(dǎo)致發(fā)動(dòng)機(jī)溫度升過高。查看有決裂和漏水表象，要及時(shí)排除。一起要堅(jiān)持足量的冷卻水，發(fā)現(xiàn)缺乏要及時(shí)增加。

Check the connecting hose of the water tank. The hose of the water tank has poor oil resistance, simple early damage, and then affects the water supply, resulting in excessive engine temperature rise. Check whether there are cracks and water leaks, and eliminate them in time. Together, we should adhere to sufficient cooling water and increase it in time in case of lack.

為確保整機(jī)的正確使用，要時(shí)間留意水溫表的讀數(shù)，到達(dá)90°以上時(shí)有必要采納辦法。可選擇就近的陰涼處泊車并以怠速降溫，留意不要立刻熄火，以避免發(fā)動(dòng)機(jī)內(nèi)部過熱而形成拉缸等事故。待溫度降下來后，還應(yīng)查看電扇皮帶的張力狀況。

In order to ensure the correct use of the whole machine, pay attention to the reading of the water temperature gauge for a long time. When it reaches more than 90 °, it is necessary to adopt measures. You can park in the nearest shade and cool down at idle speed. Be careful not to turn off the engine immediately, so as to avoid accidents such as cylinder pulling caused by overheating inside the engine. After the temperature drops, check the tension of the fan belt.

Loaders are suitable for small and medium-sized construction, and the construction site needs a lot of concrete. When proportioning concrete, most of the raw materials (stones, sand and cement) required by the construction company are transferred from the stockyard to the mixer by man-made trolleys. Small loaders are suitable for small and medium-sized construction, and the construction site needs a lot of concrete. When proportioning concrete, most of the raw materials (stones, sand and cement) required by the construction company are transferred from the stock yard to the mixer by man-made trolleys. This method of relying on manual feeding and manual transfer has high labor intensity and low production power, which is not suitable for modern production requirements; and large loaders are not suitable for use, Therefore, the agricultural tractor is refitted into a practical small loader to deal with this problem.
