Description
Technical field
The present invention relates to fluid conveyings, more particularly to the working method of pump.
Background technique
For the chemical reaction of liquid and liquid, usually two kinds or more of materials carry out according to a certain percentage
Mixing, reacts under the conditions ofs certain pressure and temperature etc..The ratio of material is generally controlled by pumping or flowmeter
It controls, pump generally uses peristaltic pump, plunger pump, gear pump or other quantifiable pumps；Flowmeter generally comprises orifice plate
Flowmeter, laminar flow mass flowmenter, turbine flowmeter, vortex-shedding meter, electromagnetic flowmeter, spinner flowmeter, ultrasonic flow
Meter and oval gear flowmeter etc., when flow is bigger, these flowmeters can satisfy the demand for control of flow, but when stream
Amount is then difficult meet demand down to certain degree；In recent years, high-accuracy stable is conveyed, especially small flow conveying, birth
Some new modes have been given birth to, the precision including improving pump, small volume flow meter etc., but consider from cost performance, the precision of pump is got over
Height, then cost is higher；Small volume flow has been calculated as acquisition small volume flow, and one side price is high, on the other hand, is easy by object
Therefore the influence, such as particulate matter, crystallization, corrosivity etc. for expecting property are not the ideal styles for solving the problems, such as this.
It aiming at the problem that pump line aging, the blocking of pump use process cause, is realized by adjusting the parameter of pump, to wriggle
For pump, when the pump line aging of pump, due to squeezing shrinkage decline, cause pump head is every to pump line to squeeze once, reality flows
Amount can be less than normal than the flow of new pump line, can be realized by accelerating the revolving speed of pump, but in order to realize that improving pump Soviet Union reaches setting
Speed, need multiple conditions: a. present speed；B. the revolving speed needed；The revolving speed needed is generally related to material properties, including
Viscosity, density etc..When pump or pipeline block, since sectional area becomes smaller, pressure may increase, flow velocity decline；In order to
Corresponding flow is obtained, it is so identical by the way of, unlike, since chocking-up degree is bigger, pressure can be bigger, and pipeline
Equal proof pressures are limited, therefore when blocking not serious, and flow velocity can be realized by accelerating the revolving speed of pump, but when blocking is arrived
To a certain degree, if continue increase revolving speed, may cause the dangerous situations such as booster, especially material be corrosive and reactivity
Material, it is even more so, therefore do not only need to know revolving speed, it is also necessary to know the acceptable range of speeds.
Due to blocking, influence of the aging for flow velocity, with certain randomness, traditional solution for the problem, one
As be to be solved by pressure detecting, traffic alignment, but there are problems that two: 1) flow is real-time change, traditional side
Method has hysteresis quality；Even if 2) know it is stifled, in addition to maintenance, without better method；3) there are security risks.This method is directed to
Problem above provides solution.
In addition, in chemical reaction, pump generally requires a process from starting to obtain stable flow, at this stage,
Since the ratio of material is not the flow according to design, the by-product of reaction is more, and the abundance of synthetic is inconsistent, causes
Product quality is abnormal, it is therefore desirable to remove the part, referred to as " pinch head "；For Research-oriented Lab or pilot plant, due to
There are it is a large amount of the fact that, therefore " pinch head " will cause a large amount of waste, even more so when Material Cost is very high.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention provides a kind of delivery precision height, response time are short
The working method of pump.

Revolving speed；
Adjustment pump, so that revolving speed reaches revolving speed corresponding with the traffic requirement；
(A4) adjustment pump, so that the flow of conveying reaches the traffic requirement of material to be conveyed.
Compared with prior art, the invention has the following advantages:
1. can adaptively don't pipe aging, pipeline or pump blocking the problems such as, the high-accuracy stable for obtaining pump is continuously conveyed,
Velocity deviation is less than 0.1%；
2. not influenced by material properties, mass flow is provided；
3. the response time is short, the time for reaching stability of flow is only in the prior art 15%；
