Description

Revolve floating single rotor flowmeter

(1) technical field

The utility model relates to a kind of measuring instrument, specifically belongs to the liquid meter instrument.

(2) background technology

At present, the piston volumeter is though overcome that the complex structure, difficulty of processing of Roots type flowmeter isometric(al) formula liquid flowmeter are big, maintenance difficult, shortcoming such as the life-span is low and the accuracy guarantee cycle is short.But itself with regard to the piston volumeter, yet conceal and depositing a fatal weakness: because its import and export are located at the top or the bottom of measuring room, when causing liquid flow, must be from the porch from top to bottom or from bottom to top through the rotor central dividing plate, again from bottom to top or the top-down exit that flow into, like this under the effect of pressure reduction, will inevitably cause the banking motion of rotor, the pitch angle of rotor will be subjected to heavy wear at the volley, cause wastage to increase, thereby the precise decreasing that causes instrument, reduce serviceable life.

(3) summary of the invention

The purpose of this utility model provides a kind of novel volumeter, it is when liquid flow, rotor can keep relative equilibrium, can be in during rotation and be bordering on suspended state, almost reaching does not have the wearing and tearing even running, and its serviceable life and the existing volumeter of accuracy guarantee period ratio increase substantially.

The utility model mainly is made up of body shell, time current divider box, cutoff board, rotor, distributing damper, the baffle plate that confluxes, suction flange, discharge flange, last current divider box, upper end cover and gear train.Body shell left side is provided with two laterally zygomorphic rectangles and divides inflow entrance, and the body shell right side is provided with the outlet of confluxing of two laterally zygomorphic rectangles; The lower end is fixed with down current divider box in the body shell, casing have into, the outlet, and with following minute inflow entrance, down conflux the outlet the position match, be provided with divided flow box in following current divider box porch, with flow liquid direction importing in accordance with regulations, central authorities are provided with measuring room in the body shell chamber, and cutoff board and rotor are contained in the measuring room; Distributing damper is contained in the left end of body shell, divides the inflow entrance sealing up and down with the body shell left end, and suction flange is equipped with at the middle part of distributing damper; The baffle plate that confluxes is contained in the right-hand member of body shell, and the body shell right-hand member is confluxed up and down exports sealing, and discharge flange is equipped with at the middle part of the baffle plate that confluxes; Last current divider box is equipped with the parts of coupled rotor gear train, last current divider box is installed in the upper end of body shell, casing have into, the outlet, its inlet, outlet respectively with last minute inflow entrance, on the conflux position of outlet match, be provided with divided flow box in the porch of last current divider box, with flow liquid direction importing in accordance with regulations; Upper end cover is equipped with the gear train of output, direct coupled rotor drive disk assembly, and their integral installations seal body shell at the top of last current divider box.The both ends of the surface of rotor process oil-guiding rail and are drilled with oil storage hole, and the rotor dividing plate is an atresia blind plate, and the center of rotor dividing plate is provided with axis hole, and outward flange one side of rotor has one and spins the mallet v notch v.

Because key character of the present utility model is to have adopted the branch inflow entrance that is respectively equipped with upper and lower two symmetries in the body shell both sides and the outlet of confluxing, and with on divide inflow entrance and on the corresponding position of outlet of confluxing current divider box is installed, with following minute inflow entrance and the following corresponding position of outlet of confluxing current divider box down is being installed, both ends of the surface at rotor process oil-guiding rail and are drilled with oil storage hole, under the effect of fluid pressure, two ends of rotor is impartial stressed simultaneously, form oil film, naturally be in oily suspended state, avoided the rotor tilt motion.So the utlity model has the beneficial effect that basic structure is reasonable, the stable accuracy cycle is long, its processing is simple, volume is little, discharge capacity is big, can be widely used in the liquid flow mearuement of various viscosity.Through facts have proved that serviceable life of the present utility model and the existing volumeter of stable accuracy period ratio have improved 2～3 times.
