Description
Technical field:
The utility model relates to a kind of teaching mode, a kind of specifically double-acting vane pump teaching mode.
Background technology:
Be widely used in the special purpose machine tool, transfer matic etc. in the machine-building at present, the vane pump in the low-pressure hydraulic system, be the dynamical element in the hydraulic system; Though the blade pump structure than gear-type pump complexity, has working pressure higher, flow pulsation is little, stable working, and noise is less, the advantage that the life-span is long.So it is widely used; The industry science Major exists and understands the comparatively problem of difficulty when the course of study aspect the hydraulic principle.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of double-acting vane pump teaching mode of being convenient to learn to understand and improving teaching efficiency.
The utility model adopts following technical scheme:
A kind of double-acting vane pump teaching mode, comprise installing plate, be contained in the rotor on the installing plate, stator, fuel tank, fuel sucking pipe, pressuring oil pipe, rotating shaft, described rotor is connected with rotating shaft by key, this rotor and stator are contained on the installing plate with one heart, be provided with installing space between the two, described stator is a loop configuration, profile ovalize in it, be evenly equipped with four through holes on its annular circumferential, should in every adjacent two through holes fuel sucking pipe and pressuring oil pipe be housed respectively, the other end of described fuel sucking pipe is connected with described fuel tank, the rounded structure of described rotor, be evenly equipped with groove on it, in this groove blade is housed, the end that this blade stretches out groove is equipped with rolling body, on this rotor handle is housed.
The utility model both can have been demonstrated pump structure The Nomenclature Composition and Structure of Complexes characteristics, can demonstrate the oil suction of vane pump again and press oily principle of work, helped the raising of teaching efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
A kind of double-acting vane pump teaching mode, referring to accompanying drawing 1, form by installing plate 1, pressuring oil pipe 2, fuel sucking pipe 3, blade 4, steel ball 5, stator 6, rotor 7, handle 8, fuel tank 9, interior profile 10, rotating shaft 11, through hole 12, key 13, groove 14, installing space 15.
Rotor 7 is housed on the installing plate 1, stator 6, fuel tank 9, rotating shaft 11, fuel sucking pipe 3, pressuring oil pipe 2, rotor 7 is connected with rotating shaft 11 by key 12, rotor 7 and stator 6 are contained on the installing plate 1 with one heart, be provided with installing space 15 between the two, stator 6 is a loop configuration, profile 10 ovalizes in it, be evenly equipped with four through holes 12 on its annular circumferential, in every adjacent two through holes 12 fuel sucking pipe 3 and pressuring oil pipe 2 are housed respectively, the other end of fuel sucking pipe 3 is connected with fuel tank 9, rotor 7 rounded structures, be evenly equipped with eight grooves 14 on it, blade 4 is housed in the groove 14, and the end that blade 4 stretches out groove 14 is equipped with steel ball 5 as rolling body, and handle 8 is housed on the rotor 7.
Rotor 7 connects by key 13 with rotating shaft 11, and when stirring handle 6, rotor 7 drives each blade 4 and rotates together.Rotor 7 and stator 6 centers overlap, stator 6 inside surface ovalizes, and this ellipse is made up of two segment length's radius arc, two sections short radius circular arcs and four transient curves.An end that stretches out groove 14 at blade 4 is equipped with steel ball 5 as rolling body, when rotor 7 rotates, blade 4 is under the effect of centrifugal force and root pressure oil, in the groove 14 of rotor 7, outwards move and press to the interior profile 10 of stator 6, steel ball 5 always is maintained on the interior profile 10 of stator 6, makes and obtains necessary sealing between rotor 7 and the stator 6.
By blade 4, the interior profile 10 of stator 6, the installing space 15 that the outside surface of rotor 7 forms is sealing, when rotor 7 turns clockwise under the control of handle 8, the seal cavity that is on the little circular arc moves in the process of orthodrome through the transition curve, blade 7 is overhanging, the volume of seal cavity increases, thereby realize that fuel sucking pipe 3 is from fuel tank 9 interior oil suctions, blade 4 from orthodrome through the transition curvilinear motion to the process of little circular arc, blade 4 is compressed into groove 14 gradually by stator 6 inwalls, the seal cavity volume diminishes, fluid is pressed in the pressuring oil pipe 2, thereby realize supply to exterior line, rotor 7 whenever circles, and each work space will be finished oil suction and press oil twice, so claim double-acting vane pump.
Present embodiment both can have been demonstrated pump structure composition, design feature; Can demonstrate vane pump oil suction each time again and press the principle of work of oil.Have simple in structurely, make easily, use easy to operate advantage.
