Description
Technical field:
The present invention relates to the hydrodynamic unit field, be specifically related to a kind of anti-runaway device that is used for the coordinative composition of equipments of small water generator group or other big inertia and needs restriction rotating speed.
Background technique:
At present; Along with scientific and technological progress and adaptation needs of economic development; The work water pressure of middle small water generator group is increasingly high increasing with energy; The safety protection of working equipment requires increasingly high, if the rotating speed of middle small water generator group or big inertia devices surpasses the permissible velocity value, will cause accident.
Summary of the invention:
The purpose of this invention is to provide a kind of two-chamber fluid coupling anti-runaway device, is working medium with liquid, with working machine and the hydrodynamic unit that the anti-runaway device connects, has the anti-runaway effect; Can control automatically working machine, easy and simple to handle, improved work situation; Product need not special maintenance, long service life, simultaneously; When working machine surpasses the permissible velocity value, play flexible braking and cross the rotating speed protection, protection working machine system.
The present invention is achieved through following technological scheme: two-chamber fluid coupling anti-runaway device; The casing that comprises working machine, forms by block and case lid, by the swivel assembly of casing supporting; Liquid-supplying system; Said swivel assembly comprises that a cover and working machine band transmission joint, the input assembly that contains two pump impellers and a cover are fixed on the casing, contains the output precision of two turbines, and said input assembly comprises input shaft, pump impeller A, pump impeller B, pump impeller connecting cylinder, shell connecting cylinder, shell; Said output precision comprises turbine A, turbine B, output shaft; Said pump impeller A and turbine A, pump impeller B and turbine B connect and form two identical active chambers, and said liquid-supplying system is fixed on the casing.
Said pump impeller A and turbine A opposite are arranged, and are formed an active chamber, turbine A and the back-to-back layout of turbine B; Pump impeller B and turbine B opposite are arranged; And form another active chamber, and the blade of some is arranged on said pump impeller A, pump impeller B and turbine A, the turbine B, be generally 42 to 60 according to active chamber big and small blade number; The blade quantity of its pump impeller and turbine differs 1 to 3, avoids producing eddy current.
During the working machine proper functioning, working machine connects through two-chamber fluid coupling anti-runaway device input shaft, drives the rotation of two pump impellers, does not have a working liquid body in the coupler rotor chamber, so two-chamber fluid coupling anti-runaway device is in unloaded state.When working machine maybe will limit rotating speed above permissible velocity, promptly need carry out the anti-runaway braking, at this moment; Connect the feed flow pipeline of two-chamber fluid coupling anti-runaway device; To the topping up in the active chamber (clear water or hydraulic transmission oil), two pump impellers of rotation this moment absorb the kinetic energy of working machine, and being converted into liquid can; Working solution flow to turbine; Turbine absorption liquid physical efficiency is converted into the heat energy of liquid, and partly liquid flows back to pump impeller and the working solution absorption kinetic energy that newly advances, and another part liquid excludes two-chamber fluid coupling anti-runaway device through conduit.When the newly-increased input kinetic energy of working machine equated with working solution absorption kinetic energy, the rotating speed of working machine just no longer raise, thereby reaches the purpose of restraint of labour machine rotating speed.
Square being directly proportional of the energy that two-chamber fluid coupling anti-runaway device absorbs and rotating speed according to law of conservation of energy, just can calculate the maximum speed of working machine.Like this, absorb at the pump impeller of two-chamber fluid coupling anti-runaway device under the effect of kinetic energy, the maximum speed of working machine just can be controlled.So adopt suitable two-chamber fluid coupling anti-runaway device, just can realize working machine anti-runaway purpose.
The present invention is that absorbing the kinetic energy energy is the twice in single chamber by the double working-chamber of two pump impellers, two turbine combinations, and the axial force that two-chamber fluid coupling anti-runaway device active chamber is produced obtains balance, thereby reaches the purpose of restraint of labour machine rotating speed; And the hydraudynamic drive resisting moment equals 2 times of single chamber; Its radial dimension and axial dimension are all little than the single chamber hydraulic brake with power, and simultaneously, output precision is fixed in block; Make two turbines of output precision can't rotate the flexible resistance of formation, eliminate the axial force in the hydraudynamic drive.
