Said intercooler 4 and the said size sum that goes up dress hydraulic efficiency pressure system cooling vessel 7 are no more than the oad of said engine radiator 5.
The concrete principle of work of technical scheme provided by the invention is following:
Last dress hydraulic efficiency pressure system cooling vessel is integrated on the refrigerating module of chassis, is positioned at the water tank front side by side with intercooler, the fan and the fan power driving device of dress hydraulic efficiency pressure system in the minimizing; Water tank, intercooler, on adorn the hydraulic efficiency pressure system cooler and be positioned at the driving engine front, carry fan by driving engine and cool off, the combined heat radiator structure is illustrated in fig. 3 shown below.
Cancellation change speed gear box cooler increases spiral fashion change speed gear box oil pipe, the spiral oil pipe is placed in the water-supplying chamber of engine radiator, utilizes the change-speed box machine oil of refrigerant fluid convection current over cooling pipe to cool off.Structure is seen Fig. 4 and Fig. 7: combined heat radiator comprise water tank, intercooler, on adorn hydraulic efficiency pressure system cooling vessel, cooling of the oil pipe.Intercooler and last dress hydraulic efficiency pressure system cooling vessel are positioned at the water tank front up and down side by side, arrange about the intercooler air inlet/outlet, on arrange about adorning the hydraulic efficiency pressure system oil inlet and outlet and also being.
Be maximum use water tank wind area, must be few intercooler and last dress hydraulic efficiency pressure system cooling vessel Width dimensional control with the water tank stand out.Intercooler is more a little bit smaller a little than water tank whole height with the height summation of last dress hydraulic efficiency pressure system cooling vessel, and the base of dress hydraulic efficiency pressure system cooling vessel is not less than the water tank lower surface in the control.Described each radiator core body all adopts aluminum material, and permeability of heat is strong, and is in light weight, and anufacturability is good.
The integral installation of combination radiating module is below the operator's compartment base plate, and vehicle front deck admission port place is positioned at the engine blower front.
For making full use of facining the wind of vehicle forward direction, adopt the air draught type fan, utilize driving engine to carry fan and cool off.Fan is selected the fan of silicon oil clutch for use, and fan noise is little, in light weight, and can satisfy the needs of whole cooling system to air quantity and pressure head.
Each radiator core body adopts aluminum tube belt structure, and heat-sinking capability is strong, and manufacturing process is simple.
Because the pump truck driving engine adopts forward type, make the split wind scooper between water tank and the driving engine, the maximum cooling effectiveness that improves fan.
Radiating module integrates, include charge air-cooling system, engine water circulating cooling system, change speed gear box oil cooled system, on adorn the hydraulic efficiency pressure system cooling system, each system's individualism is independent of each other.
Water inlet of engine water tank tool, water outlet, one remove gas port; Also be provided with one on corresponding some engine cylinder-body and remove gas port, the setting that removes gas port is in order in time to remove the water vapour that air stagnant in the refrigerant fluid and engine high-temperature produce down.
Pump truck has two kinds of operating modes, under driving cycle on dress hydraulic efficiency pressure system cooling vessel inoperative, the cold wind of fans drive mainly is that water tank and intercooler, change speed gear box machine oil are cooled off; Beating under the pump operating mode, power transmits through the direct speed of change speed gear box, and the change speed gear box oil temperature can be not higher, heat dissipation capacity is needed little.The cold wind of fans drive mainly be to water tank and intercooler, on adorn hydraulic efficiency pressure system and cool off; Because the oil circulation of change speed gear box oil pipe the inside flows; Be to carry out interchange of heat through engine coolant and oil pipe; So cancelled traditional change speed gear box oil radiator, cost has also reduced many relatively.
The engine-cooling system process is: the forced cyclic type water-cooling system is adopted on the pump truck chassis; Utilize the water pump of driving engine to enter into water tank through the engine water tank Upper hose by the high temperature coolant in the engine cylinder-body; Behind over cooling, flow out, get in the driving engine through the water tank Lower hose from the water tank lower outlet.Water tank and engine body are provided with driving engine gas removing pipe 12 and radiator gas removing pipe 11; The water vapour that air that stagnates in the refrigerant fluid and engine high-temperature produce down passes through to remove radiator gas removing pipe 11 and driving engine gas removing pipe 12 gets into secondary water tank 14; Secondary water tank 14 mainly is to refrigerant fluid an expansion space to be provided, and when the cooling liquid measure inside the water tank is not enough, in time the refrigerant fluid that liquefies is flowed back to driving engine through filling pipe.
The engine booster air cooling process is: air gets into intercooler 4 through after turbocharger supercharged through intercooler air inlet pipe 22, after intercooler 4 coolings, gets into driving engine 1.
Change speed gear box cooling of the oil process is: behind the engine running; Oil pump 19 work in the change speed gear box; Oil pump 19 passes through the connection pipe pump to lubricating oil filter 20 with the machine oil in the change speed gear box; Fil falls the impurity in the machine oil and ingress filter again and enters into water tank water-supplying chamber in-to-in spiral fashion gear box oil cooling vessel 6 through oil pipe, and refrigerant fluid cools off the change-speed box machine oil that flows through spiral cooling tube, and cooled machine oil flows back in the change speed gear box through oil return pipe.Not high or when car load warming-up operating mode when the oil temperature in the change speed gear box, can close the machine oil that leads to the machine oil spiral tube through switch valve 61 and guarantee the warming-up operating mode.
The circulation loop of last dress hydraulic efficiency pressure system cooling vessel is: pump truck is beaten the pump process or is gone up the temperature of adorning hydraulic oil in the hydraulic system processing and can raise.Hi-heat hydraulic oil is stored in hydraulic reservoir A end; The hydraulic oil of fuel tank the inside enters into dress hydraulic efficiency pressure system cooling vessel 7 through hydraulic oil pipe; Dress hydraulic pressure hydraulic cooler 7 cooled hydraulic oil get into hydraulic oil pump 15 on the process, and the high pressure oil of process hydraulic oil pump 15 gets into hydraulic actuators 17 through high pressure fuel pipe 16, and final hydraulic oil flows out from hydraulic actuator 17; Flow back into hydraulic reservoir A end through oil pipe 18, form a complete loop.The hydraulic oil of hydraulic circuit the inside constantly circulates in the loop and cools off, and guarantees that oily Wen Buhui is too high.Guarantee the normal operation of Hydraulic Elements, prolonged the life-span of part.
The present invention also provides a kind of engineering truck, comprises the vehicle chassis in the foregoing description.
The construction machinery and equipment that contains the cooling system on dress hydraulic efficiency pressure system and chassis all should be included within protection scope of the present invention, such as fire extinguishing tanker, hoisting crane etc.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
