In summer, the temperature of the excavator is high. How to choose the antifreeze properly?
If the water is not treated, scale will be generated inside the engine, the radiator box and the water tank, so that the excavator will be easily hot. Many years of on-site maintenance experience, I found that many Volvo excavators for more than 5 years, there will be high temperature problems at 3 or 4 pm in the summer, and it will not be hot when the weather turns cold. This is caused by saving money on purchasing good antifreeze. However, this is more often because users do not understand the role of antifreeze on Volvo excavators. This problem can be avoided, and it is better to add water than to choose a poor quality antifreeze.
Money for maintenance cannot be saved!
Yu Chuxiong: According to my repair experience, excavator maintenance is very important, and the money cannot be saved. If the money is not saved, the maintenance failure rate of the excavator will be very low.
The Volvo excavator repaired this morning (September 27) was out of maintenance. The hydraulic oil replacement cycle is too long, which causes the filter element to be blocked, the paper filter element is washed through, and all impurities enter the hydraulic oil, which damages the hydraulic system. This is an example of improper maintenance. I also share with you a positive example. This is the Zhuzhou Volvo user He Rong (interview on September 26) that you just interviewed. First of all, he trusted me and knew the excavator himself. His maintenance requirements are high, and almost no auxiliary parts are required. The overall maintenance cost of his excavator is not high.
