What is the interest in the suction truck plus the auxiliary engine

A suction truck vertical suction range of 7- 9 meters, in general, the vertical suction range can reach 8 meters, is a good suction truck. And horizontal suction pollution distance, generally in the case of a better seal, can be extended to 45 meters or so. This suction can already meet most people's needs.


But demand is endless, in pursuit of high suction, strong pollution car chosen vacuum pump displacement is bigger and bigger, which also caused the increase of input power and volume, traditionally, the side to take form already cannot satisfy the vacuum pump power demand, and someone came up with using a special engine driven method of vacuum pump. The auxiliary engine is connected directly to the vacuum pump with a hard connection and placed between the tank and the cab, which perfectly solves the problem of the power source of the vacuum pump.


 But then came the problem. First of all, since there is a hard connection between the engine and the vacuum pump, and there is no gear system or belt pulley system buffer when starting and closing, the instantaneous large torque load is very easy to cause shaft fracture and damage.     


Then hard connection without any speed ratio conversion mechanism, the engine output power can not match the speed required by the pump, too small pump can not play out the due efficiency, too large pump itself has irreversible damage. Such, absorb dirt car fittings to change frequently, also be bigger expenditure.


In addition, the auxiliary engine itself has a larger volume and weight, increasing the weight of the suction truck at no load, the increase of fuel consumption has played a great role, the economic cost is not cost-effective. In order to drive the vacuum pump, the auxiliary engine without transmission mechanism mostly chooses the model with much more input power than the pump, and the fuel consumption of the auxiliary engine is also an unavoidable consumption. Noise and emission of pollution is the most intuitive performance. Most of the auxiliary engines are not original products, the quality is not stable, once damaged replacement costs are daunting. 


Therefore, cheng li suction pollution car manufacturers do not recommend with a secondary vacuum suction pollution car. In the context of energy conservation and environmental protection, auxiliary engine can be said to be a technology on the verge of elimination. What is the real mainstream technology? The main is coming -- - the transfer box.     



In short, the main power of the vacuum suction tank chassis is output to different shafts through the separate box, thus driving the operation of water pump and vacuum pump. In this way, the power output of different special equipment can be achieved only by relying on the engine power of the car itself, and all the equipment can operate at the same time, which can also better match the professional power of the equipment, giving play to the best efficiency of the equipment.
