Description
Technical field
The invention belongs to the fluid machinery field of engineering technology, relate to gas-liquid delivering pump, relate in particular to gas-liquid delivering pump for high-pressure dynamic phase balance experiment.
Background technique
Phase balance experiment is the important means that obtains reflection pure substance and mixture phase behavior parameter.Phase balance experiment has static method and dynamic approach two big classes.Though static method is simple, reaching the time of balancing each other need be very long, and experimentation cost is higher.Dynamic approach can shorten the required time of balancing each other that reaches effectively, but need allow test(ing) medium circulate.That is to say that it is the key of dynamic phase balance experiment that test(ing) medium is circulated.For test(ing) medium is the situation of liquid, adopts existing liquid delivery pump just can solve.But when test(ing) medium is gas or gas-liquid two-phase, be difficult to find a kind of suitable mode of movement.Existing mode of movement, or applicable liquid only, or only adapt to gas, otherwise structure is too complicated.Especially can be used for the test(ing) medium mode of movement of high-pressure dynamic phase balance experiment, lack good solution at present.
Summary of the invention
The objective of the invention is, a kind of gas-liquid delivering pump for high-pressure dynamic phase balance experiment is provided, and it can not only be suitable for the conveying to gas, liquid and gas-liquid two-phase test(ing) medium, and simple in structure, cost is low, simultaneously can be used for high-potting, also can be used for low pressure test (LPT).
Technological scheme of the present invention is as follows:
Gas-liquid delivering pump for high-pressure dynamic phase balance experiment of the present invention.It is characterized in that: it mainly forms (all the other are conventional accessory, and as pressure measuring instruments, pipeline, valve, safety protection etc., these accessories can be provided with as required) by piston, cylinder, internal magnet, external magnet and two check valves.Piston is arranged on cylinder interior, and can be in cylinder vertically, lower slider.The piston lower end is provided with internal magnet, and the piston upper end is provided with the piston conical seal (contact) face.By this conical seal (contact) face be arranged on this piston seal steel ball above conical seal (contact) face, constituted a check valve.Piston is divided into upper chamber of air cylinder and lower chamber of air cylinder two-part with cylinder, and the upper end of piston conical seal (contact) face is communicated with upper chamber of air cylinder, and the lower end of piston conical seal (contact) face is communicated with lower chamber of air cylinder by piston channel.Between cylinder inner wall face and piston outer wall face, slipper seal is set.The cylinder lower end is provided with the medium inlet passage, and the cylinder upper end is provided with cylinder head.The cylinder head conical seal (contact) face is set in the cylinder head, and the cylinder head conical seal (contact) face has enough become another check valve with cylinder head sealed steel ball on being arranged on this conical seal (contact) face.The lower end of cylinder head conical seal (contact) face is provided with cylinder head channel, and the upper end of cylinder head conical seal (contact) face is provided with cylinder head conical seal (contact) face epicoele.The cylinder head upper end is provided with cylinder head joint, and the media outlet passage is set on the cylinder head joint, and this media outlet passage is communicated with cylinder head conical seal (contact) face epicoele.At the outer installment external magnet of cylinder, the top and bottom of external magnet are provided with upper frame and underframe respectively, by bolt external magnet, upper frame and underframe are linked into an integrated entity.External magnet, upper frame and underframe together can the cylinder outer surface vertically, lower slider.In cylinder and cylinder head, and static seal is set respectively between cylinder head and the cylinder head joint.
When above-mentioned gas-liquid delivering pump for high-pressure dynamic phase balance experiment is worked, by electronic or manual mode commonly used external magnet is moved upward vertically at the cylinder outer surface, internal magnet is under the suction of external magnet, driving piston moves upward in cylinder together vertically, be arranged on piston seal steel ball above the piston conical seal (contact) face this moment under the gravity and pressure medium effect of himself, sealing is set up in contacting point at piston conical seal (contact) face and piston seal steel ball, thereby the test(ing) medium in upper chamber of air cylinder and the lower chamber of air cylinder is isolated.When piston when cylinder surfaces axially moves upward, the volume of lower chamber of air cylinder increases, test(ing) medium just is inhaled in the lower chamber of air cylinder by the medium inlet passage; Simultaneously, the volume of upper chamber of air cylinder reduces, test(ing) medium in upper chamber of air cylinder raises its pressure because of being compressed, act on pressure medium on the cylinder head sealed steel ball poor (promptly the suffered pressure medium of upper chamber of air cylinder side and cylinder head conical seal (contact) face epicoele side poor) and overcome the gravity of cylinder head sealed steel ball self, make the cylinder head sealed steel ball break away from the cylinder head conical seal (contact) face, the test(ing) medium of upper chamber of air cylinder just enters cylinder head conical seal (contact) face epicoele by cylinder head channel, discharges by the media outlet passage that is communicated with therewith again.When external magnet drives piston along the cylinder surfaces axial downward movement by internal magnet, the volume of upper chamber of air cylinder increases, pressure medium in the upper chamber of air cylinder descends, under the effect that being arranged on cylinder head sealed steel ball on the cylinder head conical seal (contact) face can be poor at the suffered pressure medium of self gravitation and cylinder head sealed steel ball (promptly cylinder head conical seal (contact) face epicoele side and the suffered pressure medium of upper chamber of air cylinder side poor), fall back on the cylinder head conical seal (contact) face, and set up sealing in the contacting point of cylinder head sealed steel ball and cylinder head conical seal (contact) face, stoped the test(ing) medium in the cylinder head conical seal (contact) face epicoele to enter upper chamber of air cylinder; Simultaneously, because the pressure medium in the upper chamber of air cylinder descends, act on pressure medium on the piston seal steel ball poor (promptly lower chamber of air cylinder side and the suffered pressure medium of upper chamber of air cylinder side poor) and overcome the gravity of piston seal steel ball self, make the piston seal steel ball break away from the piston conical seal (contact) face, the test(ing) medium in the lower chamber of air cylinder just is inhaled in the upper chamber of air cylinder.Repeat above-mentioned piston under external magnet drives along axial the moving up and down of cylinder surfaces, test(ing) medium will constantly be inhaled into lower chamber of air cylinder and discharge upper chamber of air cylinder via medium inlet passage and media outlet passage, thereby finishes the conveying to test(ing) medium.
Should be noted that in order to give full play to the action effect of sealed steel ball own wt in two above-mentioned check valves piston and cylinder are preferably along its axial vertical setting to sealing.Should be noted that also no matter test(ing) medium is gas, liquid gas, or gas-liquid two-phase, above-mentioned course of conveying can both be finished smoothly.
Advantage of the present invention and effect are: gas-liquid delivering pump for high-pressure dynamic phase balance experiment provided by the invention is simple in structure, is applicable to that simultaneously test(ing) medium is the occasion of gas, liquid and gas-liquid two-phase, also is applicable to the conveying of high pressure and low pressure simultaneously.
