Cement Mixer Truck Hydraulic Drive System

Hydraulic Drive System of Cement Mixer Truck:

1. The hydraulic system of cement mixer truck is a closed circuit which is composed of reducer, variable piston pumps and motors.
2. Reducer, piston pumps, hydraulic motors selection adopts the Italian companies products such as cement mixer truck special products, providing excellent output performance and long life.
3. Hydraulic oil grades used are: Mobile (Mobil) -DTE26, Shell (Shell) -Tellus 68 hydraulic oil at low temperatures should be used Mobile (Mobil) -DTE15M.
4. Fill gear oil is a heavy load vehicle gear oil, grade GL-5 (GB13895-1992) viscosity grade 85W / 90 (according to GB / T14906-1994); at low temperatures you should use Shell Spirax (Spirax) ASX lubricating oil.
5. In order to meet the minimum start-up temperature (lower limit temperature) requirements, preheating system is essential, when the ambient temperature is below -5 ℃, no matter what kind of grade lubricants, preheat for at least 10 minutes.
6. Hydraulic Drive System with automatic temperature protection device. In the working temperature exceeds 65 ℃, the temperature control switch automatically opens, a cooler to work, when the working temperature is below 60 ℃, the thermostat switches off automatically coolers stop working.
