Description
Technical field
The present invention relates to a kind of No leakage discharge opeing dividing plate, especially a kind of combination No leakage discharge opeing dividing plate being applicable to the contactless rotor pump of eccentric center translation of gas-liquid delivery.
Background technique
Eccentric center translation non-contact type rotor pump (pump with swinging rotor) is a kind of fluid machinery that the mechanical energy of prime mover can be converted to the pressure potential being transferred fluid, its working principle is: utilize the plane motion of rotor to define the main transfusion effect of pump, form one between pump rotor and pump case to cut off with pump discharge, with a volume of inlet communication, along with the motion of rotor, this volume increases gradually, rotor reaches and a part for this volume and pump inlet is also cut off subsequently, finally, this volume is connected with delivery side of pump again, and the liquid under the motion of rotor in this volume is gone out by exclusion, be mainly used in the conveying of multi phase state material and the application of pressurization.
Because eccentric center translation rotor pump adopts contactless design, gap between rotor and pump case there will be the leakage of medium, and two stiff dough relative movement can cause the problems such as rotor wearing and tearing and material expansion when rotor lubrication is insufficient, finally be easy to cause seal clearance to lose efficacy, the suction capacity of pump declines.Therefore, improve sealability, increase another key problem that transfer efficiency is semirotary pump field.
Particularly, in the process of gas-liquid delivery, the leakage rate of gas will be far longer than the leakage speed of liquid, and existing various swing-rotor pump structure is difficult to the backflow of barrier gas, cause the head pressure of semirotary pump and volumetric efficiency all lower, limit the application area of pump with swinging rotor in conveying gas-liquid two-phase medium.
Therefore how improving eccentric center translation rotor pump, improve the sealability of rotor pump, increase transfer efficiency, improving the reliability of rotor pump is all need the problem of solution badly.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of structure and simply combines No leakage discharge opeing dividing plate.
In order to solve the problems of the technologies described above, the invention provides a kind of combination No leakage discharge opeing dividing plate; Comprise discharge opeing dividing plate and roller and rectangle barrier film; Described roller is sleeved on discharge opeing dividing plate; Described discharge opeing dividing plate upper end arranges rectangle barrier film.
Improvement as to combination No leakage discharge opeing dividing plate of the present invention: described rectangle barrier film is interfixed by pressing plate and discharge opeing dividing plate; Described pressing plate is made up of top board and press table, and the upper end of described rectangle barrier film is compressed by top board and press table; The upper end of described press table and discharge opeing dividing plate interfixes.
Further improvement as to combination No leakage discharge opeing dividing plate of the present invention: described top board is provided with upper locating slot, corresponds to locating slot, press table is provided with lower locating slot.
Further improvement as to combination No leakage discharge opeing dividing plate of the present invention: be provided with apocenosis passage in described discharge opeing dividing plate.
Further improvement as to combination No leakage discharge opeing dividing plate of the present invention: the lower end of described discharge opeing dividing plate is provided with cylindrical channel.
Further improvement as to combination No leakage discharge opeing dividing plate of the present invention: the lower end of described apocenosis passage is provided with liquid port.
Further improvement as to combination No leakage discharge opeing dividing plate of the present invention: be provided with stiffening ring in described rectangle barrier film.
Further improvement as to combination No leakage discharge opeing dividing plate of the present invention: described roller comprises metal layer, and described metal layer is outside equipped with non-sticking lining.
Further improvement as to combination No leakage discharge opeing dividing plate of the present invention: described non-sticking lining is modified Teflon.
Apocenosis passage is built in the discharge opeing dividing plate of vertically layout by combination No leakage discharge opeing dividing plate of the present invention, and dividing plate is longer, and potted line lengthens, and import increases, and improves suction performance, eliminates instantaneous backflow; Simultaneously, rectangle barrier film is adopted above dividing plate, moving up and down of rectangle membrane engagement dividing plate, discharge the stage at medium, dividing plate moves upward, and diaphragm cavity volume increases, in barrier film, pressure medium reduces, liquid medium enters diaphragm cavity under the effect of pressure reduction, realizes roller and discharge opeing dividing plate and the leaf envelope effect between roller and the pump housing, hinders the backflow of gas; At the sucting stage of medium, dividing plate moves downward, and correspondingly barrier film internal pressure increases, and forces in gas discharge side; So the suction of medium and discharge stage all achieve the only export but no import of gas, there is not gas backstreaming to low pressure, fully achieve the No leakage of gas.
Swing up and down operating mode for what coordinate discharge opeing dividing plate, and full swing amplitude is 3.2 degree, all puts stiffening ring, adds working life, reduce radial dimension inside and outside rectangle barrier film, convenient for installation and maintenance.
Better swing up and down to make discharge opeing dividing plate, improve the sealability of dividing plate and roller, in roller, material is metal, the modification PTEF of outsourcing layer, plastic material, wear-resisting, the line performance that rises is good, and partition movement heating makes PTEF expand, gap between seal diaphragm and pump chamber, therefore sealing and greasy property good, the life-span is long, strong shock resistance.
Comprehensive above-described characteristic, beneficial effect of the present invention is as follows: adopt combination No leakage discharge opeing dividing plate, liquid port direction is vertical, reduce radial dimension, the dividing plate of discharge opeing is simultaneously larger, increase apocenosis passage, improve suction performance, eliminate instantaneous backflow, further, dividing plate media of both sides adopts rectangle barrier film to separate, the pressure balance of medium is realized while dividing plate can be coordinated to swing up and down operating mode, achieve the No leakage of gas, all put stiffening ring inside and outside rectangle barrier film simultaneously, convenient for installation and maintenance, with metal outsourcing modification PTEF in roller, the line performance that rises is good, sealing and greasy property good, life-span is long, impact resistance is strengthened.
