Description
Technical field：
It the utility model is related to a kind of hydraulic dynamometer circulating form, and in particular to a kind of through-flow knot of novel hydropower dynamometer
Structure.
Background technology：
Hydraulic dynamometer is now widely used for a variety of original machine power testing fields, as prime mover load test
Pay(useful) load, can measure the power output of prime mover, while coordinate prime mover to carry out various working point transformation experiment.Often at present
Hydraulic Dynamometry Rotor, the stator seen use blade shape, and when measuring original machine power, rotor follows prime mover to rotate, and stirs
The dynamic water entered inside dynamometer, water transfers torque to stator and housing, and drives stator case with respect to dynamometer base
Small angle rotation, stator and this movement tendency of housing unit are prevented by tension-compression sensor component, and are passed by pressure
Sensor measures drawing（Pressure）The size of power, the power of prime mover can be obtained in conjunction with torque arm length and rotating speed.But this dynamometer by
Limited in blade construction, cavitation is serious, particularly under high speed conditions, therefore does not adapt to prime mover work(of higher rotation speed
Rate measurement demand, it is necessary to which measurement could be matched with dynamometer by increasing decelerator after prime mover.So design a kind of novel hydropower
Structure that dynamometer is through-flow is very necessary.
Utility model content：
The utility model is made up and improved in place of above-mentioned the deficiencies in the prior art, there is provided a kind of new hydraulic dynamometer is inhaled
The flow-through format of power is received, reduces cavitation erosion, adapts to high rotating speed original machine power measurement demand.It can promote and make on a large scale
With.
The technical solution adopted in the utility model is：A kind of through-flow structure of novel hydropower dynamometer, the structure include left half
Housing, dividing plate, stator, rotor, main shaft, axle sleeve, the first connecting bolt, the second connecting bolt, the 3rd connecting bolt, right half-shell body
And sealing ring, dividing plate are fixed on left shell half body and right half-shell body by the first connecting bolt respectively, stator passes through the second connection
Bolt is fixed on left shell half body, and left shell half body is connected with right half-shell body by the 3rd connecting bolt, and composition hydraulic dynamometer leads to
Sealed among the stator water chamber of stream part, left shell half body and right half-shell body by sealing ring, the rotor is fixed on by axle sleeve
On main shaft, dynamometer rotor assembly is formed.
The beneficial effects of the utility model：It is simple in construction, it is reasonable in design, compared with traditional vane type hydraulic dynamometer,
Because it is relatively stable in the flow characteristics during absorbed power in hydroecium, the generation of cavitation phenomenons is reduced；Disc type
Through-flow structure type, the measurement of high rotating speed or ultrahigh rotating speed original machine power is adapted to, avoids some high rotating speed equipment from surveying
The situation of decelerator must be installed during amount additional, system and intermediate link power loss is simplified, saved cost, improve survey
The precision of amount；Structure type that disc type is through-flow can be achieved two-way compared with traditional vane type under the conditions of a through-flow hydroecium
Rotational Absorption power, the volume of dynamometer is substantially reduced, has saved cost.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Reference picture 1, a kind of through-flow structure of novel hydropower dynamometer, the structure include left shell half body 1, dividing plate 2, stator 3, turn
Son 4, main shaft 5, axle sleeve 6, the first connecting bolt 7, the second connecting bolt 8, the 3rd connecting bolt 9, right half-shell body 10 and sealing ring
11, dividing plate 2 is fixed on left shell half body 1 and right half-shell body 10 by the first connecting bolt 7 respectively, and stator 3 passes through the second connection
Bolt 8 is fixed on left shell half body 1, and left shell half body 1 and right half-shell body 10 are connected by the 3rd connecting bolt 9, and composition waterpower is surveyed
Sealed among the stator water chamber of work(device flow passage component, left shell half body 1 and right half-shell body 10 by sealing ring 11, the rotor 4 is logical
Cross axle sleeve 6 to be fixed on main shaft 5, form dynamometer rotor assembly.
According to hydraulic dynamometer absorbed power and design requirement, to reduce cavitation phenomenons, improve dynamometer operation and turn
Speed, it is necessary to improve streamflow regime in the through-flow structure of dynamometer, using disk type rotor form, current enter from the root of rotor 4 of dish type
Enter, outer ring outflow, the rotor 4 for being measured equipment belt Moving plate shape rotates in water, under the influence of centrifugal force stator water chamber outer ring
A circle water ring is formed, in dynamometer running, rotor 4 interacts with the current in water ring, delivers torque to stator 3,
Stator 3 is driven, by the pressure of pull pressure sensor measurement now, to be grown relative to dynamometer Small-angle Rotation in conjunction with the arm of force
Degree and rotating speed can obtain the power of prime mover.Simultaneously as the symmetrical structure of disk type rotor, in a stator water chamber, you can
Realize 4 positive and negative two direction of rotation absorbed powers of rotor.
When dynamometer works, water, equipment under test rotor driven are full of in the cavity between rotor assembly and stator water chamber
Component rotates, and rotation dish type rotor banding moves current and water ring is formed on the outside of stator water chamber, under the effect of flow viscosity power, through-flow portion
Water-dividing chamber（Including left and right housing, stator, dividing plate etc.）With the rotating tendency with spindle assemblies equidirectional, passed by pressure
Sensor measures moment of torsion and power.Heat can be produced the liquid level rotated against simultaneously between, so as to which the power of equipment under test be turned
It is changed to the temperature rise of water.
