攪拌車如何更換液壓油？

液壓泵分為齒輪泵，葉片泵，柱塞泵，螺桿泵。而攪拌機(jī)一般使用的是柱塞泵。

The hydraulic pump is divided into gear pump, vane pump, plunger pump and screw pump. The mixer generally uses a plunger pump.

齒輪泵一般選用低灰液壓油，對要油品要求一般。葉片泵可選用低灰或無灰的液壓油。柱塞泵和螺桿泵都是使用無灰的液壓油，因其部件的設(shè)計(jì)精密對液壓油的灰分特別嚴(yán)重。柱塞泵使用的無灰液壓油除了要求無灰，對油品的氧化安定性要求也很高，市售一般氧化安定/min測試約300。當(dāng)然也有添加劑能達(dá)1000以上。

Gear pumps generally use low ash hydraulic oil, with general requirements for important oil products. Vane pump can use low ash or ash free hydraulic oil. Both plunger pump and screw pump use ashless hydraulic oil. Because of the precise design of its components, the ash content of hydraulic oil is particularly serious. The ashless hydraulic oil used in the plunger pump not only requires ashless, but also has high requirements for the oxidation stability of the oil. The commercial general oxidation stability / min test is about 300. Of course, there are additives that can reach more than 1000.

攪有些客戶在購買商品混凝土水泥攪拌運(yùn)輸車后，一般改裝廠家會(huì)給用戶壹本操縱手冊，而這個(gè)操縱手冊上應(yīng)該有明確的要求齒輪油以及液壓油的標(biāo)號(hào)。對付液壓系統(tǒng)原則上夏季利用68#的抗磨液壓油，冬季應(yīng)該利用46#的抗磨液壓油，寒冷地區(qū)應(yīng)該利用32#的低溫抗磨液壓油。這樣做的長處是液壓系統(tǒng)內(nèi)油的循環(huán)越發(fā)順利，不會(huì)因?yàn)楦邷赜偷恼吵矶冗_(dá)不到，造成液壓油系統(tǒng)不能正常運(yùn)轉(zhuǎn)。

After some customers purchase the commercial concrete cement mixer truck, the general modification manufacturer will give the user an operation manual, which should have clear requirements for the label of gear oil and hydraulic oil. In principle, for the hydraulic system, the anti-wear hydraulic oil used 68# in summer, 46# in winter and 32# in cold areas should be used. The advantage of this is that the oil circulation in the hydraulic system is more and more smooth, and the hydraulic oil system will not operate normally because the viscosity of high-temperature oil cannot be reached.

混凝土攪拌車更換液壓油的步驟：

Steps for replacing hydraulic oil of concrete mixer truck:

（1）放開油箱卸油堵有頭；

(1) Release the oil unloading plug of the oil tank;

（2）松開馬達(dá)卸油堵油頭；

(2) Loosen the motor oil discharge plug;

（3）松開泵側(cè)的回油管接頭放油；

(3) Loosen the oil return pipe connector on the pump side to drain the oil;

（4）油放完后，重新裝好卸油堵油頭及回管；

(4) After the oil is drained, reinstall the oil discharge plug and return pipe;

（5）在油箱內(nèi)加入指定的油液；

(5) Add the specified oil into the oil tank;

（6）松開泵上稍高的卸油口，看殼體是否注滿了油；

(6) Loosen the slightly higher oil discharge port on the pump to see if the housing is filled with oil;

（7）同樣檢查馬達(dá)殼體是否注滿了油，檢查是否保持和馬達(dá)的清潔；低速啟動(dòng)引擎2-3次，確定無異常后，低速發(fā)動(dòng)引擎（800-1000rpm）約10分鐘；熱機(jī)后，逐漸拉動(dòng)操縱桿到傾斜角，檢查有無異常，如果一切正常，就可以正式使用了。

(7) Similarly, check whether the motor housing is filled with oil and whether the and motor are kept clean; Start the engine at low speed for 2-3 times. After confirming that there is no abnormality, start the engine at low speed (800-1000 RPM) for about 10 minutes; After heating up the engine, gradually pull the control lever to the maximum inclination angle to check whether there is any abnormality. If everything is normal, it can be officially used.
