The Tianluo truck we see in our daily life is called the mixer truck. Now let's introduce the whole of the mixer truck. Let's start with the description of the hydraulic drive system, electrical system and water supply system of the mixer truck.
Hydraulic drive system
The hydraulic system is a closed circuit composed of reducer, variable piston pump and motor.
The lubricating oil filled in the reducer is heavy-duty vehicle gear oil, brand GL-5 (gb13895-1992), viscosity grade 85w/90 (according to gb/t14906-1994); In low temperature environment, shell Spirax ASX lubricant should be used.
In order to meet the requirements of low starting temperature (low limit temperature), please use preheating system if necessary. When the ambient temperature is lower than -5 ℃, no matter what grade of lubricating oil is used, preheat for at least 10 minutes.
The system has automatic temperature protection device. When the working temperature exceeds 65 ℃, the temperature control switch automatically opens and the cooler starts to work. When the working temperature is lower than 60 ℃, the temperature control switch automatically closes and the cooler stops working.
The electrical system of the mixer truck is mainly the cooling fan control part.
The start and stop of the cooling fan is automatically controlled by the temperature switch. The fan starts when the temperature is higher than 65 degrees and stops when the temperature is lower than 60 degrees. The temperature switch is located on the cooler, and the relay and fuse are in the power relay box next to the battery.
Water supply system
The water supply system of automatic feeding mixer is composed of pressure water tank, water gun, water pipe, valve, etc. The volume of the water tank is about 380 liters, and pneumatic water supply is adopted. The main function is to wash the hopper after loading and the mixing drum and discharge chute after discharging, so as to prevent the concrete from sticking. When the temperature is lower than zero degrees Celsius, the water stored in the water tank and water pipe should be drained after washing to prevent freezing.
The above is all about the problems and precautions introduced to you today. I hope it can help you. If you want to know more, you can contact us by phone or follow our website http://www.zkhntjbj.com , our staff will contact you in time.
