Description
Technical field
The utility model relates to cement viscosity detection device technical fields, measure more particularly to a kind of cement consistency
Use potentiometer.
Background technique
Pointer is contacted with the bridging type that resistor disc belongs to traditional approach in current potentiometer, stability shortcoming, pointer
Generate the inaccuracy for loosening and will lead to measurement numerical value.The limit of not position is arbitrarily slided in the place that pointer and resistor disc contact
Fixed, pointer may mark the range effects calibration of resistor disc.Also have one to potentiometric tune " 0 " in the case where no limit
Fixed influence.The potentiometric spring of tradition is mounted in potentiometric top, such structure after finishing experiment cleaning just at
Problem, and the poor linearity of spring can be made if once covering cement slurry in an experiment to influence the data knot of experiment
Fruit.
Utility model content
The main purpose of the utility model is to provide a kind of cement consistency measurement potentiometer, cement consistency measurement
There is easy to adjust, the high feature of accuracy of measurement with potentiometer.
The technical solution adopted in the utility model is:
A kind of cement consistency measurement potentiometer, axis (2) are held by deep-groove ball axis (16) and are mounted on table on main body (1)
Aforementioned body (1) is disc structure in the centre bore in face, the lower end of axis (2) is provided with rotary table, transmission ring (5) is mounted on
It states on rotary table, conductive sheet (12) is mounted on potentiometer main body (1) by conductive pillar (7), and one end of scroll spring (15) connects
Connect scroll spring positioning column (8), the other end of scroll spring (15) is mounted on axis (2), torsional spring (13) first with potentiometer
Conductive pointer (3) is installed, and then conductive pointer (3) is fixed on potentiometer axis (2), the tail portion of conductive pointer (3)
It is fastened with screw, limit hook (14), power spring locking post (9) and probe contact spring (11) are mounted on main body (1)
On.
Further, above-mentioned deep-groove ball axis (16) is made of ceramic materials.
Further, above-mentioned conductive pillar (7) and conductive sheet (12) are three.
The utility model has the advantage that and good effect are as follows:
1. the design applies clipping pointer, it is not necessarily to remove in calibration process that tune " 0 " can be facilitated.
2. pointer and resistor disc contact position use torsional spring, torsional spring has automatic compensation function, and pressing force is adjustable, and contact is stablized
Property it is more preferable, guarantee in the bad situation of resistor disc flatness, pointer and resistor disc are in contact condition always, and the data made are more
It is accurate to add.
3. scroll spring is located at potentiometer bottom surface, avoid since cement slurry accumulates the influence to spring.
4. three extraction pillars, cooperation engineer can be used for introducing electric current when calibrating, also other generally applicable calibrators, usually
It is supported used as potentiometer.
5. calibrated using calibrator, for potentiometer without rotation, cooperation Special turntable measurement stability is higher.
6. potentiometer has pointer limit design, pointer is protected.Preventing pointer is more than resistor stripe range, leads to no data
Display.

Specific embodiment
As shown in Figures 1 to 4, the utility model is a kind of cement consistency measurement potentiometer, comprising: main body 1, axis
2, conductive pointer 3, pointer gasket 4, transmission ring 5, hook blocks 6, conductive pillar 7, scroll spring positioning column 8, power spring locking
Column 9, resistor disc 10, probe contact spring 11, conductive sheet 12, torsional spring 13, limit hook 14, scroll spring 15, deep groove ball bearing
16。
Axis 2 is mounted on inside main body 1 by deep groove ball bearing 16, and transmission ring 5 is mounted on the lower part rotary table of axis 2,
Conductive sheet 12 is installed on the body 1 by conductive pillar 7, and 15 one end of scroll spring connects the installation of 8 one end of scroll spring positioning column
On axis 2, resistor disc 10 is installed in main body annular groove, and torsional spring 13 is installed with conductive pointer 3 first, then will be referred to
Pincushion piece 4, conductive pointer 3, pointer gasket 4 are fixed on tail portion on potentiometer axis 2 in order and are fastened with screw, adjust " 0 "
Then this screw of Shi Songdong is installed limit hook 14, hook blocks 6, power spring locking post 9 and probe contact spring 11
In potentiometer main body 1.
In use, blade positioning ring and blade drive block are fixed on blade axis first, then put slurry cup into autoclave body
Motor is opened later, is connected in place with and the determination coaxially connected with slurry cup axis by potentiometer is hooking means, while ensuring current potential
Probe contact spring 11 in meter contacts well with each probe, and whether observation consistometric value is normal.
As preferred: above-mentioned deep-groove ball axis 16 is made of ceramic materials.
Above-mentioned conductive pillar 7 and conductive sheet 12 are three.
In above preferred embodiment:
1, pointer is by using clamp-type, so that adjusting more convenient.2, scroll spring is mounted on bottom, effectively prevents bullet
Spring is influenced by cement slurry.3, spring is used in pointer and resistor disc contact position, effective solution contact is incomplete
Problem.4, corrosion-resistant using ceramic bearing, frictional force is small, long service life.
The utility model can allow potentiometer more stable during the experiment using ceramic bearing, and experimental data is more acurrate.
The utility model replaces common pointer using torsional spring, allows pointer and resistor disc to contact more preferable, experimental data is more acurrate.This is practical
It is novel that scroll spring is placed on potentiometer in the following, reducing influence of the cement to it in experiment, increase service life.
The above is the specific example of the utility model, and is not construed as limitations of the present invention, all uses
The technical solution that equivalent or equivalent transformation is formed, still falls within the protection scope of the present utility model.
