Description of drawings
Fig. 1 is the schematic diagram of a kind of static equipment starting drive of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but not as limiting to the invention.
Fig. 1 is the schematic diagram of a kind of static equipment starting drive of the present invention, and is shown in Figure 1.A kind of static equipment starting drive of the present invention includes a prime mover 1, and this prime mover 1 is internal-combustion engine.One static equipment, this static equipment are the compressor 2 with heat pump, and prime mover 1 is by transmission shaft 3 drive compression machines 2.One flywheel 4, this flywheel 4 rotatably is arranged on transmission shaft 3 by bearing 5.One starting drive, this starting drive are used for driving flywheel 4 and rotate.Also include a clutch 6, this clutch 6 is controlled flywheel 4 and is accessed on transmission shaft 3 and separate.When starting static equipment, at first control flywheels 4 by clutch 6 and separate with transmission shaft 3, when flywheel 4 reaches one enough during fast pre-set velocity, clutch 6 is connected to drive prime mover 1 with static equipment in conjunction with prime mover 1.
The present invention also has following mode of execution on the basis of the above:
In the first embodiment of the present invention, please continue shown in Figure 1.Starting drive is a motor 8 and the slip gear 7 that driven by this motor 8, on gear 7 surfaces that make starting drive finally act on to contact with flywheel 4, flywheel 4 is the gear of taper, makes gear 7 contact with flywheel 4 and separate by an axial movement.
In the second embodiment of the present invention, include a control unit 10 and an actuating motor 9, this clutch 6 is controlled by this control unit 10 and is controlled by this actuating motor 9.Also include a velocity transducer 11, this velocity transducer 11 receives the speed data of flywheel 4, and this speed data is transferred to control unit 10.If data are pulse shapes that the frequency relevant to flywheel 4 rotating speeds occurs, control unit 10 can be had an effect.For example: the commutation pulse signal is analogue signal, and this analogue signal reference voltage level consistent with access and separating rate compares.Based on the state of these comparisons and prime mover 1, no matter prime mover 1 is start or cut out, and the logical level line that control unit 10 generates is controlled actuating motor 9 and clutch afterwards 6.
In the third embodiment of the present invention, the speed that the speed of clutch 6 access flywheels 4 is separated flywheel 4 higher than clutch 6.
In the fourth embodiment of the present invention, the signal that the running of clutch 6 generates by actuating motor 9 speed of response sensors 11, and in this rate signal and control unit 10, default signal value compares, to control actuating motor 9.
In the fifth embodiment of the present invention, after starting drive is separated in flywheel 4 access clutches 6.
Be activated when device is in resting state, gear 7 is in separated state with transmission shaft 3; To act on the angular wheel of flywheel 4 by the gear 7 of being controlled by motor 8 to drive when namely prime mover 1 and compressor 2 are activated.After reaching a predetermined toggle speed, Negotiation speed sensor 11 passes to control unit 10 with data, action control clutch 6 accesses of actuating motor 9 response control units 10.Prime mover 1 just is activated by the rotation of flywheel 4 like this.Between clutch 6 access periods or afterwards, gear 7 separates from the friction surface of flywheel 4.
Clutch 6 can move automatically according to the speed of flywheel 4.Clutch 6 is not manually to be controlled access and separated by the operator, automatically controls but reach default speed by flywheel 4.More suitably that clutch 6 should access than causing clutch 6 to separate under the higher rotating speed of rotating speed.At first, guaranteed like this until before flywheel 4 obtained an enough high speed, clutch 6 will can not continue access, enough complete the startup that realizes prime mover 1 such as this speed, and kept the equipment that links together with prime mover 1 and run well.Secondly, clutch 6 should separate under a relatively low speed, even to guarantee that static equipment that prime mover 1 drives still can turn round when the low-down speed, sometimes, this speed may be lower than toggle speed.At last, drop at 0 o'clock at rotating speed, flywheel 4 can not keep connecting with transmission shaft 3, hazardous condition occurs to avoid prime mover 1 when extremely low speed is moved.
Be disposed in flywheel and by the startup between the transmission shaft of the heat pump compressor of a reciprocating piston prime mover driven for clutch, so design: clutch should access and start prime mover when flywheel reaches 1000rmp, and should be at a lower degree of turning when being limited in 600rmp and the flywheel disengaging.The disengaging of clutch may make prime mover no longer from the smooth-going driving torque of flywheel output, and prime mover may will be shut down because of self reason like this.If namely the torsion characteristic of prime mover is not in the situation that have inertial mass can not keep the independent operation of prime mover, such shutdown will occur.Following four-stroke prime mover of 4 cylinders for example.The prime mover that has the One's name is legion cylinder may need special closing method, for example turns off fuel oil supply system or turn off ignition system to make prime mover shut down device.
Clutch operating is controlled also and can be realized by the data of some special system acquisition and processing flywheel.Also can automatically perform access and separating action by the perception rotating speed.
These are only preferred embodiment of the present invention; not thereby limit embodiments of the present invention and protection domain; to those skilled in the art; should recognize that being equal to that all utilizations specification of the present invention and diagramatic content done replace and the resulting scheme of apparent variation, all should be included in protection scope of the present invention.
