Abstract
The utility model designs a thermal balance system and a voltage-stabilized water supply system matching a hydraulic dynamometer. During a working process, the hydraulic dynamometer is thus enabled to keep water in cycle use in a normal temperature through a cooling system of the hydraulic dynamometer itself. A voltage-stabilization overflow device is further arranged in a matching way. The voltage-stabilization overflow device keeps water entering the hydraulic dynamometer under a stable pressure. The working state stability of the hydraulic dynamometer is also guaranteed. Meanwhile, thanks to the overflow effects, the service lifetime of a water pump can be effectively protected.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic dynamometer.
Background technology
For the power machines such as engine are carried out to power, the test of rotating speed, need to use dynamometer, general dynamometer is in fixed position, to carry out work, the power of its absorption is taken away (as common hydraulic dynamometer and eddy current absorption dynamometer) by external chilled water, also have by electrical network and export electric energy (as Electric Dynamometer), but when the needs because of engine test technique, when dynamometer must be worked while moving, originally dynamometer is just not too suitable, if current use amount is at most also the most general hydraulic dynamometer, two basic demands that he uses, to there is water source endlessly to take away heat and stable water supply pressure, in mobile status, be just difficult to meet.Also someone attempts original waterpower to survey device use in mobile status at present, but the energy that has occurred the engine that absorbs because of dynamometer constantly raises water temperature, thereby the revolving part, the seal rapid wear that cause dynamometer, simultaneously, owing to there is no the water source of voltage stabilizing, make the loading of dynamometer unstable, and the water pump supplying water is also perishable.
The utility model has designed heat balance system and pressure-stabilizing water supply system a kind of and that hydraulic dynamometer is supporting; make hydraulic dynamometer when work; can make by the cooling system of self water recycling be stabilized at normal temperature; also supporting voltage stabilizing overflow mechanism; make the water that enters hydraulic dynamometer keep stable pressure; namely guarantee the stable of hydraulic dynamometer duty, simultaneously owing to there being the effect of overflow, can effectively protect the mission life of water pump.
With the supporting heat balance system of hydraulic dynamometer, the turning axle that utilizes exactly hydraulic dynamometer directly or drive water pump and fan work by belt, chain, water pump provides the water source of need of work for hydraulic dynamometer, in confession (going out) water lines of water pump, seal in heating radiator, and fan faces heating radiator, with regard to the water that makes to recycle, be able to cooling like this.
Pressure-stabilizing water supply system is exactly, on water pump is supplied with the water route of hydraulic dynamometer, a bypass is set, and a voltage stabilizing surplus valve is set in bypass, and bypass is got back to water tank after by voltage stabilizing surplus valve.So both guaranteed to enter the stable water pressure of hydraulic dynamometer, the direct recovery tank of superfluous water that makes again water pump confess, can not make water pump because rotating speed is excessive or the excessive overload that causes of hydraulic pressure.

Embodiment
In Fig. 1, engine 25 and hydraulic dynamometer 15 are arranged on dynamometer mounting base 12, and dynamometer mounting base 12 and water tank 1 and water pump support 8 are installed as one.
During work, engine 25 can make by the shaft coupling 24 of engine and dynamometer hydraulic dynamometer 15 rotations, hydraulic dynamometer 15 is by dynamometer main shaft 14 and dynamometer belt pulley 13 rotation that is connected with it, thereby drive belt 4 and fan pulley 3 and water pump fan shaft 2 rotary works, water pump fan shaft 2 drive fan 5 and water pump 11 work.
Hydraulic dynamometer 15 rotarily drives 23 work of simple and easy generator, and simple and easy generator 23 provides power supply and tach signal for the tachometer gage 22 on instrument panel 21.
During hydraulic dynamometer 15 rotation, because of the water resistance effect between the stator and rotor in cavity, the housing of hydraulic dynamometer 15 is swung, by gear train, make hydraulic dynamometer display disc 16 indicate the current absorption torque value of hydraulic dynamometer 15, by the calculating with tachometer gage 22 displayed values and the fan of demarcating while dispatching from the factory and the summation of water pump consumed power value, can obtain the measurement performance number of engine.
During water pump 11 work, water is sucked by pump water inlet 6 from water tank 1, and by pumping line 9, the water that has certain pressure is conveyed into heating radiator 10, water enters radiator outlet pipe 7 after heating radiator 10, by flow control valve 20, enter in the chamber that hydraulic dynamometer water inlet pipe 17 flows to hydraulic dynamometer 15, water is got back to water tank 1 after absorbing energy the uniform temperature that raises, on radiator outlet pipe 7, front end at flow control valve 20, be provided with a voltage stabilizing overflow bypass 19, in voltage stabilizing overflow bypass 19, voltage stabilizing surplus valve 18 is installed, voltage stabilizing surplus valve 18 can make the water in radiator outlet pipe 7 keep the constant pressure of setting, thereby make the stable working state of hydraulic dynamometer 15, the surplus valve of voltage stabilizing simultaneously 18 also makes unnecessary water be back to water tank 1.
During work, by the aperture of adjust flux variable valve 20, can control the water yield that enters dynamometer 15, thereby reach the effect of control, adjusting power of engine.
5 pairs of heating radiators of fan 10 blowing during work, at the water of water tank 1, it is carried out during through heating radiator 10 cooling, thereby the water temperature of whole system is controlled in the reasonable scope.
