Description

A kind of hydraulic dynamometer reverse flow cooling system
Technical field
The utility model patent is related to hydraulic dynamometer equipment technical field, more particularly, to suitable for such as(Petrol engine, Diesel engine, natural gas, liquefied petroleum gas engine, combustion gas turbine, motor, gearbox, fluid torque-converter)Performance test When dynamometer machine cooling system.
Background technology
Pipeline connection and cooling water quality are the important safety guarantees of hydraulic dynamometer, using during dynamometer machine it is initially noted that Be whether hydraulic pressure, water-carrying capacity and cooling water leaving water temperature reach defined requirement.In order to ensure that dynamometer machine can over a long time just Often work, generally adds a kind of G1 antisludging agents in recirculated cooling water, to prevent fouling in pipeline after dynamometer machine long-term use, influences Cooling effect;If cooling water leaving water temperature is higher than 65 °, it is easy to cause dynamometer machine to damage.And long-term use of common G1 resistances Dirty agent easily causes the deposition of reverse osmosis membrane water pollution and colloid pipeline organic matter on film, and adds experimental cost, therefore In the dynamometer machine experiment of reality, the type of cooling for effectively solving hydraulic dynamometer is still a technical barrier.
The content of the invention
Dynamometer machine is caused to damage to solve the problems, such as that cooling water leaving water temperature is too high, a kind of waterpower provided by the utility model Dynamometer machine reverse flow cooling system.
The present utility model is that technical scheme is used by solving its technical barrier:A kind of described waterpower measurement of power Machine reverse flow cooling system, including water tank, it is characterized in that the top for also including described water tank is provided with tank lid, water tank left part is set There is heat abstractor, water tank front portion is provided with water plug.
Described heat abstractor includes:Connection sleeve pipe, swan neck I, straight tube I, fin, swan neck II, return pipe and Standpipe.The cooling water output system of return pipe front end and dynamometer machine is connected, and return pipe rear end is connected by swan neck II and fin It is logical;Fin connects by straight tube I, swan neck I, standpipe and connection sleeve pipe with water tank again, and the device mainly forms fin The space temperature difference produce the fluid in space residing for fin and produce reverse flow, realize the efficient of radiating.
Described water plug includes:Tube valve, left flange, centrifugal pump, right flange, draining tap, straight tube III, elbow Pipe III, return riser and straight tube IV.Centrifugal pump front end is connected by left flange, tube valve, straight tube IV with water tank, centrifugal pump rear end Connected by right flange, draining tap, straight tube III, swan neck III with return riser, the device, which primarily serves, makes the cold of dynamometer machine But the effect that water circulation is got up, wherein draining tap primarily serve the effect that winter experiment is allowed to dry water after terminating, and prevent a water Case and frost crack pipe.
A kind of beneficial effect of described hydraulic dynamometer reverse flow cooling system is that the reverse flow cooling system is by its fin The fluid that the space temperature difference of formation can produce space residing for fin produces reverse flow, realizes the efficient of radiating, effectively solution The certainly Water Cooling Technology problem of hydraulic dynamometer, it has the features such as simple in construction, cost is cheap, reliable operation.
Brief description of the drawings
Fig. 1 is the principle main structure diagram of the present invention.
Fig. 2 is Fig. 1 of the present invention overlooking the structure diagram.
Fig. 3 is Fig. 1 of the present invention left view structural representation.
1. water tanks, 2. tank lid, 3. connection sleeve pipes, 4. swan necks I, 5. straight tubes I, 6. fin, 7. swan necks in figure IIth, 8. return pipes, 9. tube valves, 10. left flanges, 11. centrifugal pumps, 12. right flanges, 13. drainings tap, 14. straight tubes III, 15. swan neck III, 16. return risers, 17. standpipes, 18. straight tubes IV.
Embodiment is described in further detail below in conjunction with the preferred example shown in accompanying drawing:
In Fig. 1,2,3, a kind of described hydraulic dynamometer reverse flow cooling system, including water tank(1), it is characterized in also wrapping Include described water tank(1)Top be provided with tank lid(2), water tank(1)Left part is provided with heat abstractor, water tank(1)Front portion is provided with Water plug.
In the embodiment shown in fig. 1, described heat abstractor includes:Connection sleeve pipe(3), swan neck I(4), straight tube I (5), fin(6), swan neck II(7), return pipe(8)And standpipe(17).Return pipe(8)The cooling water of front end and dynamometer machine is defeated Go out system connection, return pipe(8)Rear end passes through swan neck II(7)With fin(6)Connection;Fin(6)Pass through straight tube I again (5), swan neck I(4), standpipe(17)And connection sleeve pipe(3)With water tank(1)Connection.
In the embodiment depicted in figure 2, described water plug includes:Tube valve(9), left flange(10), centrifugal pump (11), right flange(12), draining tap(13), straight tube III(14), swan neck III(15), return riser(16)With straight tube IV (18).Centrifugal pump(11)Front end passes through left flange(10), tube valve(9), straight tube IV(18)With water tank(1)Connection, centrifugal pump (11)Rear end passes through right flange(12), draining tap(13), straight tube III(14), swan neck III(15)With return riser(16)Even It is logical.
During work, a kind of hydraulic dynamometer reverse flow cooling system passes through return pipe(8)The cooling water of front end and dynamometer machine is defeated Go out system connection, cooling water passes through fin(6)It flow back into water tank(1)Interior, it is producing reverse flow in space residing for fin It is dynamic, pass through fin(6)Surface distributes heat, realizes the purpose of radiating, then water tank(1)Interior cooling water passes through centrifugal pump (11)It is pumped into return riser(16)It is interior, make the cooling water circulation of dynamometer machine, it is achieved thereby that the adverse current cooling system The general function of system.
