Abstract

The utility model relates to a turbine-type variable flow infusing unit for corrosion resisting flow determination for measuring various acid, alkali, oxidant and organic solvent in the high temperature of 150 DEG, which can work at a long time. Consisting of a fluorine plastic casing, a fluorine plastic vane wheel, a fluorine plastic rotating shaft, a magnetic steel, a fluorine plastic front bearing seat, a fluorine plastic back bearing seat, an induction coil with an iron core and a fluorine plastic bearing. The utility model of the structure has the advantages of simple structure, corrosion resistance and long service life.

Description

Turbine-type variable flow infusing unit for corrosion resisting flow determination

The utility model belongs to the device that a kind of measurement has the corrosive fluid flow, and the conventional turbine transducer of usefulness is not corrosion-resistant at present, particularly detects the flow of strong acid, highly basic, strong oxidizer and organic solvent.

The purpose of this utility model provides a kind of corrosion-resistant flow measurement turbine transducer, and it is characterized in that can be 150 ℃ of following long-term works, anti-various acid, alkali, oxygenant and various organic solvent.

The purpose of this utility model realizes by following approach, two bearing seats made from fluoroplastic are installed in a shell made from fluoroplastic, place one on the bearing seat inner face string therein and have inductive coil unshakable in one's determination, the centre of diaxon bearing is equipped with an impeller made from fluoroplastic, be evenly equipped with several glasss of magnet steel on the end face of impeller, thereby formed a corrosion resistant flow measurement turbine transducer.

This corrosion resistant flow measurement with turbine transducer have simple in structure, good corrosion resistance, the life-span is long, precision is high (being generally the 0.1-0.3 level), characteristics such as easy to use.It is the best instrument of measuring at present with corrosive fluid.

Described in detail below in conjunction with the structure and the operating position of accompanying drawing utility model:

Figure one is a structural representation of the present utility model

Figure two is a rear bearing block end view drawing of the present utility model

Figure three is an impeller end view drawing of the present utility model

By figure one as can be seen, the utility model is by fluoroplastic housing 1, fluoroplastic impeller 2, and fluoroplastic rotating shaft 3, magnet steel 4, fluoroplastic front-end bearing pedestal 5, fluoroplastic rear bearing block 6 has inductive coil 7 unshakable in one's determination, and fluoroplastic bearing 8 is formed.Front-end bearing pedestal 5 and rear bearing block 6 are contained in respectively in the inner chamber of housing 1, see figure one, on front-end bearing pedestal 5 and rear bearing block 6 bearing 8 are housed respectively, and the impeller 2 that end face is equipped with several glasss of sealing magnet steel 4 is installed in the rotating shaft 3, together erects rotating shaft 3 by two bearings 8.Impeller 2 is rotated flexibly, see figure one and figure three, an inductive coil 7 with iron core that is sealing is installed on the end face muscle of rear bearing block, see figure one and figure two, have the information that the inductive coil that mills the heart is used for detecting wheel speed, its principle is a magneto-electric induction.Owing to several magnet steel of sealing are installed on the impeller 2, just have several electric pulses to input to secondary instrument whenever one week of wheel rotation.

Because fluoroplastic have good corrosion resistance, high temperature resistant, characteristics such as friction factor is minimum, so the utility model just can be 150 ℃ of following long-term works, can anti-various acid, alkali, oxygenant and various organic solvent.

Can be found out that by above situation the utility model result is simply novel, have good corrosion resistance, long, precision high of life-span, so be requisite flow survey tool on the present Chemical Manufacture. A kind of anti-rotten flow measurement is promoted the use of with turbine transducer, will bring many convenience for producers, and produce good social benefit.
