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.
Requirements for hydraulic oil of automatic feeding concrete mixer truck:
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.
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.
Note: it is strictly prohibited to mix gear oils of different brands and models.
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.
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.
