Hydraulic oil, as the power source in the hydraulic system of concrete mixing and conveying pumps, needs to have good wear resistance, oxidation resistance, corrosion resistance, and anti-foaming properties. Our pump trucks all recommend using No. 46 anti-wear hydraulic oil. So, what should we do to better protect our hydraulic system when using the pump truck to transport concrete?

1. Before adding hydraulic oil to the oil tank, we need to perform a thorough cleaning.

2. Concrete mixing and conveying pumpWhen injecting new hydraulic oil, it must be filtered; otherwise, it will affect the performance of the hydraulic system and the service life of the hydraulic pump.

3. Regularly check the quality of the hydraulic oil and the oil level. Ensure that the temperature of the oil in the tank does not exceed the specified range for hydraulic oil, generally not exceeding 60°. If the oil temperature is too low, preheat the oil. The machine can only be operated after the oil temperature gradually rises.

There is a certain temperature difference between the northern and southern regions, and workers operating the pump truck in different places need to have certain experience. It is important to note that.Concrete mixing and conveying pumpThe oil temperature of the hydraulic system should be between 35-55°. Once the temperature rises above 60°, it will affect the performance of the equipment and is particularly prone to failure. Therefore, when operating the pump machine, closely monitor the working temperature of the hydraulic oil.
