In the hot summer months, some drivers have to keep the cooling water temperature as low as possible in order to prevent the engine temperature of the suction truck from becoming too high. Some drivers simply remove the thermostat to achieve the purpose of cooling. of. Concrete Mix Truck was used to transport construction concrete of special truck; cylindrical mixing drum to carry the concrete mixed on trucks. During transport always kept stirring drum rotation to ensure that concrete does not carry solidification. After the delivery of finished concrete, usually rinsed with water inside the mixing drum, to prevent residual concrete hardening space, so the volume of the mixing tube is less and less.
Concrete mixer truck device component by truck chassis system and the concrete mixing system . China's production of concrete mixer truck chassis to use more vehicle manufacturers to provide two types of GM chassis. Its special mechanism includes power take off, mixing drum frame, gearbox, hydraulic systems, the mixing tube, the control mechanism, cleaning system.
Working principle is that by PTO take out Truck chassis power,
and drive hydraulic system of the variable pump, the mechanical energy into
hydraulic energy to quantitative motor, motor and drive reducer, reducer drive mixing plant, for mixing concrete. Concrete Mix Truck Concrete Mix Truck,Concrete Pump Truck,Concrete Mixture Truck Suizhou lishen special vehicle co.,ltd , https://www.ls-truck.com
Because the suction truck engine is both hot and cold, if the cooling water temperature is too low, fuel combustion will deteriorate, fuel consumption will increase, wear and tear will increase, oil viscosity will increase, and engine power will decrease. At low temperatures, the viscosity of the lubricant is high and the lubrication is not satisfactory. The gap between the piston and the cylinder, the gap between the bearing and the gear gap are all reduced, which accelerates wear. At the same time, unburned fuel scours cylinder liners and damages the oil film, resulting in poor lubrication, and wear of cylinder liners, pistons, and piston rings is accelerated. Fuel can not be completely burned, it will reduce economic efficiency and increase pollution. The long-term operation of diesel engines at temperatures below 60 degrees Celsius will cause the engine to gel due to incomplete combustion, that is, gums will adhere to the combustion chamber, valves, and injectors, affecting engine performance.
If the temperature of the cooling water of the suction truck is too high, the temperature of the lubricating oil will rise and become too thin, and it will be difficult to form a lubricating film with the auxiliary surface, and semi-dry friction or even dry friction will occur. At the same time, because the cylinder temperature is too high, the cylinder wall oil is easy to scorch and deposit carbon, which promotes accelerated wear of the components. In severe cases, it can cause accidents such as pulling cylinders, holding shafts, and burning tiles.
Suspension truck manufacturers many years of tests show that when the car cooling water temperature is 40-50 degrees Celsius, the engine wear increased by 60% -80%, power decreased by 25%, fuel consumption increased 8% -10%. Therefore, the temperature of the engine cooling water is not as low as possible, and should generally be controlled between 80-90 degrees Celsius.
