Abstract
The utility model relates to a dynamometer, comprising a stable blade type hydraulic dynamometer, a water storage tank, a water inlet conduit and a water outlet conduit, wherein, the water inlet conduit is provided with a pressure regulating water pump; the point near the water inlet is provided with a water inlet bypass conduit; the water inlet bypass conduit is provided with a fast bypass valve; the water outlet conduit is provided with a fast valve, a pressure releasing water tank and an ordinary water pump. The utility model can realize rapid loading and unloading, and can complete the test of the dynamic performance of an internal-combustion engine with high-power.
Description
The utility model is a kind of quick response fluid power dynamic force gauge, belongs to measuring technology.
Current, the response dynamics dynamometer is the key equipment of internal combustion engine dynamic performance testing fast, is badly in need of this class testing equipment at present both at home and abroad.Set about developing this equipment mid-term from the eighties abroad, so far, Austria AVL company has developed the straight inversion Electric Dynamometer of the friendship with low inertia, and (power is 120KW, every price 960 Schillings difficult to understand), West Germany Schenck company develops the quiet attitude dynamometer that surges, the both has the fast outstanding feature of response, and the problem of existence is: the cost height is difficult to realize high-power.
The purpose of this utility model provides a kind of measurement of power equipment of high performance price ratio, can realize the quick loading and the unloading of fluid power dynamometer, can finish the test of heavy duty dynamic property.
This dynamometer, form by steady blade formula fluid power dynamometer 1, reserve tank 2, inlet channel 3 and outlet conduit 4, pressure regulation water pump 5 and reserve tank 2 are housed on the inlet channel 3, be connected to another water inlet by-pass line 11 near water inlet 9 places, on water inlet by-pass line 11, a quick by-pass valve 12 is housed, near water delivering orifice 10 places quick-action valve 7, pressure release water tank 8 and common water pump 6 is housed on the outlet conduit 4.
The utlity model has high performance price ratio, promptly be applicable to high-power dynamic test, also be applicable to the dynamic test of internal-combustion engine of middle low power.Simultaneously, the stable state fluid power dynamometer with domestic widespread usage of the dynamic measurement of power of this fluid power serves as that realize on the basis, so have prospect and the remarkable economic efficiency of applying.
Concrete structure of the present utility model is provided by accompanying drawing 1.
Fig. 1 is the structural drawing of dynamometer.
Primary structure among the figure is: steady blade formula fluid power dynamometer 1, reserve tank 2, inlet channel 3, outlet conduit 4, pressure regulation water pump 5, common water pump 6, quick-action valve 7, pressure release water tank 8, water inlet 9, water delivering orifice 10, water inlet by-pass line 11, quick by-pass valve 12, ergometer 13, ring flange 14.
Below in conjunction with accompanying drawing the utility model is specified.
During work, the water in the water tank makes water outlet be transferred to required working pressure through the pressure regulation water pump, charges into stable state fluid power dynamometer then.When quick loading, quick by-pass valve to cut out, quick-action valve cuts out simultaneously, and at this moment, the water in the reserve tank can instantaneously be full of steady blade formula fluid power dynamometer, thereby the braking torque of dynamometer is risen rapidly, to realize quick loading.During unloading, open quick by-pass valve rapidly, cut off the water inlet of steady blade formula fluid power dynamometer, simultaneously, open quick-action valve, the water in the steady blade formula fluid power dynamometer is discharged fast.In order to reduce the outlet conduit resistance, be provided with the pressure release water tank in the quick-action valve outlet, make water enter the pressure release of pressure release water tank immediately, improved the rate of discharge of steady blade formula fluid power dynamometer water to the greatest extent, realized fast discharging.When the pressure release water tank was filled, water was pumped into reserve tank through light water, and then periodic duty.Under steady-state working condition, by-pass valve is regulated continuously fast, and the intake pressure of keeping dynamometer is constant.The form of quick-action valve is pneumatic or hydraulic pressure, and steady blade formula fluid power dynamometer is by engine or driven by motor.This dynamometer has been used for 1200KW steady blade formula fluid power dynamometer, and loading and unloading speed has reached 1000Nm/sec.Price is low, absorbed power is big because steady blade formula fluid power dynamometer itself has, so this dynamometer utility model has realized heavy duty dynamic test and high performance price ratio.
Claims (1)
1, a kind of dynamometer, form by steady blade formula fluid power dynamometer 1, reserve tank 2, inlet channel 3 and outlet conduit 4, it is characterized in that: pressure regulation water pump 5 and reserve tank 2 are housed on the inlet channel 3, be connected to another water inlet by-pass line 11 near water inlet 9 places, on water inlet by-pass line 11, a quick by-pass valve 12 is housed, near water delivering orifice 10 places quick-action valve 7, pressure release water tank 8 and common water pump 6 is housed on the outlet conduit 4.
