Description
Technical field
The present invention relates to fluid viscosity proving installation in mechanical engineering, being specially can test fluid viscosity the one list cylinder rotary viscosimeter instrument of realtime curve fast.
Background technology
Viscosity is one of the important physical character and technical indicator of fluid, along with the development of commercial production and scientific research, measure viscosity or the mobility of flowing material, become a requisite substances test, it has consequence in the quality control of production link and the assessment of performance of final products, and to appraising the quality of a product, seeking, best production technology and the development of new products all play a part very important.Therefore, in commercial production and basic science, utilize viscosity apparatus to be very important to measure the performance rule of viscosity and grasp viscous state.
The method measuring viscosity at present both at home and abroad mainly contains blood capillary tube method, rotary process, Constructional Elements Using Falling Methods, viscosity agar diffusion method and vibratory drilling method etc., the viscosity meter of corresponding principle is had to be applied to reality for often kind of method, as capillary viscosimeter, rotational viscosimeter, Engler (Engler) viscosity meter, Redwood (Redowood) viscosity meter, Saybolt (Saybolt) viscosity meter, twisting vibration viscosity take into account vibrating-plate viscosimeter etc.
In long-term practical application dissimilar viscosity meter all more or less expose respective shortcoming, easily adhere on the capillary as capillary viscosimeter use procedure medium thus affect it and normally measure, therefore need to safeguard continually, not only disturb production scene but also increase operating cost, the more important thing is, capillary viscosimeter is only applicable to Newtonian fluid in the uniform measurement justified in straight tube when doing laminar flow; Rotational viscosimeter is the most frequently used commercial measurement viscosity meter, is applicable to Newton and non-Newton fluid, but required hardware device is more, and complex structure is expensive; Although it is simple and easy to do that Constructional Elements Using Falling Methods measures viscosity, be only limitted to simply measure the higher liquid of viscosity, and measuring accuracy is relatively low; Viscosity agar diffusion method is measured viscosity and is faced the problems such as measuring accuracy is low equally, is mainly used in factory or laboratory etc. at present and makes rough Viscosity Analysis.
Summary of the invention
The problem that in order to solve existing viscosity meter, the present invention exists that measurement range is limited, measuring accuracy is low, expensive and complex structure needs periodic maintenance, provides a kind of single cylinder rotary viscosimeter instrument.
The present invention adopts following technical scheme to realize: a kind of single cylinder rotary viscosimeter instrument, comprise opening U-shaped frame to the right, the wall surfaces of U-shaped frame is provided with data handling system, horizontal adjustment instrument, guidance panel and panel control system, the upper wall of U-shaped frame is fixed with guide pole, guide pole is provided with the orienting lug slided up and down thereon, and the upper end of guide pole is fixed with connection bracket, decelerating step motor is provided with above connection bracket, the output shaft of decelerating step motor is connected with the leading screw through connection bracket and orienting lug, leading screw lower end and top are provided with the bearing be connected with U-shaped frame and connection bracket, leading screw bottom cover has the screw pair be connected with orienting lug, connection bracket and U-shaped frame upper wall right-hand member are provided with travel switch, the rear end of orienting lug is fixed with sealed cylinder, sealed cylinder upper end is provided with stepper motor, elastic hollow axle is provided with in sealed cylinder, the two ends up and down of elastic hollow axle are all fixed with the multidiameter that adjacent side diameter is greater than opposing side diameter, the output shaft of stepper motor is connected with the multidiameter being positioned at upside, multidiameter on the downside of being positioned at is connected with replaceable rotor, and the cascaded surface of two multidiameters is all fixed with code-disc, and sealed cylinder inwall is provided with the photoelectric sensor be plugged on each code-disc.
Before the work of single cylinder rotary viscosimeter instrument, first the container filling appropriate viscous liquid to be measured is placed on the upper surface of U-shaped frame lower wall, eye-level adjustment instrument and suitably adjusting gear to being in horizontality, operation control panel, driving decelerating step motor works, drive screw turns, orienting lug is driven to move up and down along guide pole, and then drive replaceable rotor slowly to go deep in liquid to be detected, on observation liquid level arrival rotor till assigned scale line place, different rotating speeds can be in make accurate adjustment in the process by controlling decelerating step motor, if this process occurs that maloperation causes measurement mechanism position to exceed measurement range, touching travel switch can cause system alarm to be pointed out, dangerous situation is avoided to occur, when after replaceable rotor movement to assigned address, stepper motor is started by guidance panel, replaceable rotor produces moment of torsion in the opposite direction rotated, torque signal is passed to the outer corner difference of code-disc, and the umber of pulse difference that collect two photoelectric sensors send processes by data handling system by the outer corner difference of code-disc, calculate the viscosity of measured matter, shown by guidance panel.Overcome existing viscosity meter and have that measurement range is limited, measuring accuracy is low, problem that expensive and complex structure needs periodic maintenance.
Reasonable in design of the present invention is reliable, the detection of torque signal is carried out by making digital torque sensor by oneself, use stepper motor to be directly connected with torque sensor as power source thus on a large scale, adjust arbitrarily the rotating speed of viscosity meter, rotating speed gear is not had to limit, and realize freely being elevated of measurement mechanism by panel operation Driving Stepping Motor, realize accurately controlling the degree of depth that rotor enters liquid, enormously simplify the measurement of physical quantity, have that to measure accurate, easy and simple to handle, test specification extensive, the advantage of data storing, display in real time.
