搅拌车如何更换液压油?

来源:https://www.jfjiaobanche.com 浏览:发表时间:2022-01-08
液压泵分为齿轮泵,叶片泵,柱塞泵,螺杆泵。而搅拌机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.
齿轮泵一般选用低灰液压油,对要油品要求一般。叶片泵可选用低灰或无灰的液压油。柱塞泵和螺杆泵都是使用无灰的液压油,因其部件的设计精密对液压油的灰分特别严重。柱塞泵使用的无灰液压油除了要求无灰,对油品的氧化安定性要求也很高,市售一般氧化安定/min测试约300。当然也有添加剂能达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.
搅有些客户在购买商品混凝土水泥搅拌运输车后,一般改装厂家会给用户壹本操纵手册,而这个操纵手册上应该有明确的要求齿轮油以及液压油的标号。对付液压系统原则上夏季利用68#的抗磨液压油,冬季应该利用46#的抗磨液压油,寒冷地区应该利用32#的低温抗磨液压油。这样做的长处是液压系统内油的循环越发顺利,不会因为高温油的粘稠度达不到,造成液压油系统不能正常运转。
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.

混凝土搅拌车更换液压油的步骤:
Steps for replacing hydraulic oil of concrete mixer truck:
(1)放开油箱卸油堵有头;
(1) Release the oil unloading plug of the oil tank;
(2)松开马达卸油堵油头;
(2) Loosen the motor oil discharge plug;
(3)松开泵侧的回油管接头放油;
(3) Loosen the oil return pipe connector on the pump side to drain the oil;
(4)油放完后,重新装好卸油堵油头及回管;
(4) After the oil is drained, reinstall the oil discharge plug and return pipe;
(5)在油箱内加入指定的油液;
(5) Add the specified oil into the oil tank;
(6)松开泵上稍高的卸油口,看壳体是否注满了油;
(6) Loosen the slightly higher oil discharge port on the pump to see if the housing is filled with oil;
(7)同样检查马达壳体是否注满了油,检查是否保持和马达的清洁;低速启动引擎2-3次,确定无异常后,低速发动引擎(800-1000rpm)约10分钟;热机后,逐渐拉动操纵杆到倾斜角,检查有无异常,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.
