The invention has the advantages of continuous liquid supply and the like.
Description
Technical Field
The invention relates to liquid quantification, in particular to a continuous liquid supply method.
Background
At present, the liquid is quantified generally by using a flowmeter, which generally comprises a pore plate flowmeter, a laminar flow mass flowmeter, a turbine flowmeter, a vortex shedding flowmeter, an electromagnetic flowmeter, a rotor flowmeter, an ultrasonic flowmeter, an elliptic gear flowmeter and the like, when the flow is relatively large, the flowmeters can meet the control requirement of the flow, but when the flow is low to a certain degree, the requirement is difficult to meet; in recent years, new ways for high-precision stable transportation, especially small-flow transportation, have been created, including improving the precision of pumps, small-volume flow meters, and the like, and the defects mainly lie in:
1. in consideration of cost performance, the higher the precision of the pump is, the higher the cost is; in order to obtain small volume flow, the small volume flow meter has high price on one hand;
2. the flowmeter is easily influenced by material properties such as particles, crystallization, corrosivity and the like, and the service life of the flowmeter is shortened;
3. in view of the limited volume of the container, the fluid cannot be continuously supplied to the outside, for example, when the liquid in the container is about to be discharged, the supply of the liquid is stopped, and the liquid is supplied after being replenished.
Disclosure of Invention
In order to solve the defects in the prior art, the invention provides a continuous liquid supply method.
The invention aims to be realized by the following technical scheme:
a continuous liquid supply method, comprising:
a first container is placed on a first electronic scale, and the mass m of the liquid in the first container is displayed1；
A second electronic scale on which a second container is placed, for displaying the mass m of the liquid in the second container2(ii) a The liquid in the second container is intermittently fed into the first container, so that the liquid in the first container is continuously supplied, and the mass flow rate of the supplied liquid is (-Delta m)2-Δm1)，Δm2Δ m being the reading change of said second electronic scale1And the indication change of the first electronic scale is obtained.
Compared with the prior art, the invention has the following beneficial effects:
1. by intermittently supplying the liquid, it is possible to continuously supply the liquid at a certain flow rate to the outside, and it is possible to accurately supply the liquid to the outside even when the liquid is supplied;
2. a flowmeter is not needed, the cost is reduced, and the problems of corrosion and the like are not needed to be worried;
Detailed Description
The following description describes alternative embodiments of the invention to teach those skilled in the art how to make and reproduce the invention. Some conventional aspects have been simplified or omitted for the purpose of teaching the present invention. Those skilled in the art will appreciate that variations or substitutions from these embodiments will be within the scope of the invention. Those skilled in the art will appreciate that the features described below can be combined in various ways to form multiple variations of the invention. Thus, the present invention is not limited to the following alternative embodiments, but is only limited by the claims and their equivalents.
Example 1:
a continuous liquid supply method, comprising:
a first container is placed on a first electronic scale, and the mass m of the liquid in the first container is displayed1；
A second electronic scale on which a second container is placed, for displaying the mass m of the liquid in the second container2(ii) a The liquid in the second container is intermittently fed into the first container, so that the liquid in the first container is continuously supplied, and the mass flow rate of the supplied liquid is (-Delta m)2-Δm1)，Δm2Δ m being the reading change of said second electronic scale1And the indication change of the first electronic scale is obtained.
To replenish the liquid, the liquid in the second container is either self-flowed or by pumping the first container.
In order to keep the pressure consistent, the first container and the second container are closed, one end of the gas pipeline is communicated with the upper part of the liquid level in the first container, and the other end of the gas pipeline is communicated with the upper part of the liquid level in the second container.
If Δ m is necessary to continuously supply the liquid1If the liquid in the second container is less than 0, the liquid in the second container needs to be supplemented into the first container;
if Δ m1If the rate is more than 0, the completion is informed or the completion rate is reduced.
Example 2:
an application example of the continuous liquid supply method according to embodiment 1 of the present invention.
In this application example, the continuous liquid supply method is:
the first container is placed on the first electronic scale, and the displayIndicating the mass m of the liquid in said first container1；
A second electronic scale on which a second container is placed, for displaying the mass m of the liquid in the second container2(ii) a The liquid in the second container is intermittently fed into the first container, so that the liquid in the first container is continuously supplied, and the mass flow rate of the supplied liquid is (-Delta m)2-Δm1)，Δm2Δ m being the reading change of said second electronic scale1The indication change of the first electronic scale is obtained;
if Δ m1If the pressure is less than 0, the liquid in the second container needs to be supplemented into the first container, and the liquid in the second container flows automatically or is pumped into the first container;
if Δ m1If the pressure is more than 0, stopping the feeding or reducing the feeding speed to prevent the liquid in the first container from overflowing
In order to keep the pressure consistent, the first container and the second container are closed, one end of the gas pipeline is communicated with the upper part of the liquid level in the first container, and the other end of the gas pipeline is communicated with the upper part of the liquid level in the second container, so that the pressure balance between the first container and the second container is ensured.
