The hydraulic system is the operation center of the loading part of the whole automatic loading concrete mixer. The value of the whole hydraulic system accounts for about 40% of the loading part, because these hydraulic systems are basically imported parts.

自动上料混凝土搅拌车 液压油的要求：

Requirements for hydraulic oil of automatic feeding concrete mixer truck:

客户在置办混凝土罐车后，普遍改装厂家会给用户壹本操作手册，而这个操作手册上都会有明白的要求齿轮油以及液压油的标号。关于液压系统准则上夏季使用68#的抗磨液压油，冬季应该使用46#的抗磨液压油，严寒地区应该使用32#的低温抗磨液压油。这样做的益处是不管何时，都会使液压系统内油的循环愈加顺利，不构成由于低温或者高温油的稀薄度达不到，造成液压油系统不能正常运转。

After the customer purchases the concrete tank truck, the general refitting manufacturer will give the user an operation manual, which will have clear requirements for the label of gear oil and hydraulic oil. As for the hydraulic system guidelines, the anti-wear hydraulic oil used 68# in summer, the anti-wear hydraulic oil used 46# in winter and the low-temperature anti-wear hydraulic oil used 32# in severe cold areas should be used. The advantage of this is that at any time, the oil circulation in the hydraulic system will be more and more smooth, which does not cause the hydraulic oil system to fail to operate normally due to the lack of thinness of low-temperature or high-temperature oil.

减速机加注齿轮油，普通的标号VG150,也能够加注企业较好的壳牌等加注变速箱的高能齿轮油。

Gear oil can be added to the reducer, ordinary grade vg150, and high-energy gear oil can also be added to the gearbox, such as shell.

注意一点：严禁不同企业不同型号的齿轮油混加。

Note: it is strictly prohibited to mix gear oils of different brands and models.

普通状况下，液压油和齿轮油更换应该在购车之日起一个月内或者400个工作小时好。这样更能保证厂家的售后和液压系统的正常运转。曾经有一次，一个客户通知我，他自从买车到往常(2年)了，没有改换过油，车辆还是好好的运转。我不承认有这种事情存在，但是没有及时换油省下的几千块钱，等到坏的时候不是几千块就能处置的，典型的贪低价吃大亏。据不完整统计，造成液压系统损坏的，95%是由于没有及时更换液压油造成的。

Under normal circumstances, the replacement of hydraulic oil and gear oil should be completed within one month or 400 working hours from the date of purchase. This can better ensure the normal operation of the manufacturer's after-sales and hydraulic system. Once, a customer told me that he had not changed the oil since he bought the car (2 years), and the car was still running well. I don't admit that this kind of thing exists, but I didn't change the oil in time. I saved thousands of dollars. When it was bad, I couldn't handle it. The typical greedy low price suffered a heavy loss. According to incomplete statistics, 95% of the damage to the hydraulic system is caused by the failure to replace the hydraulic oil in time.

更换过之后，需要根本上每半年一年更换一次问题都不大。中间要注意液压风扇上的散热指示针，假如发现油品有问题，应立刻改换。

After the replacement, it needs to be replaced every half a year to once a year, which is not a big problem. In the middle, pay attention to the heat dissipation indicator on the hydraulic fan. If there is a problem with the oil, change it immediately.
