Abstract
The utility model relates to a special small -size oil pump of PVT relation experiment, include pump pole, the pump body, oil pressure gauge interface, cock seal valve, send oily interface. Be equipped with oil through, precession spiral and sealing washer clamp plate in the cock of cock seal valve. When concerning the assembly of laboratory glassware totality with the supporting PVT of this special small -size oil pump, with the oil inlet butt joint of the mercury box on oily interface of sending of this special small -size oil pump and the supporting instrument. Be full of experiment gas, mercury solution, pump oil expenses to supporting instrument in proper order. Before the experiment, stable back is settled to the instrument of will forming a complete set, just opens cock seal valve and the gas cylinder valve of instrument body on this oil pump pump body. During the experiment, the pressurization is realized to clockwise rotation pump pole, the release is realized to counter -clockwise turning pump pole. The utility model discloses compact structure, the scale of construction is small and exquisite, easy preparation, easy and simple to handle, the reliability is high, and the suitability is strong, agrees with the miniaturized demand of laboratory glassware, the suitable popularization.
Description
Technical field
This utility model relates to experimental apparatus design field.
Background technology
Carbon dioxide PVT relationship experiments instrument is that the environment of universities and colleges, the energy, chemical industry, machinery etc. are about one of professional Engineering Thermodynamics Course experiment common instrument.Its cardinal principle is to push mercury solution by oil pump force feed, the experimental gas in mercury solution recompression gas cylinder, and the process of change and gas-liquid phase transition to observe each index in gas PVT relation, checking is relevant theoretical.
The oil pump of existing PVT relationship experiments instrument adapted, the pressure gauge tester of many employing finished products is as sending oil and pressure to show.Its scale of construction is big, and active connection place is many.Its pressurized operation flow process is: closes and send fuel tap, opens pressure gauge valve and lubricating cup valve, rotate pump rod counterclockwise, and once oil inhaled by oil pump；Closing lubricating cup valve, open and send fuel tap, turn clockwise pump rod, and pumping is oil once, so many takes turns operation.Unload the similar reverse of press operation.The easy maloperation of student new hand, causes that instrument breaks down and lost efficacy.
Summary of the invention
In order to solve, the existing PVT relationship experiments oil pump scale of construction is big, operating process is complicated, instrument failure easily occur and the problems such as inefficacy, and this utility model provides a kind of PVT relationship experiments special small oil pump.
Concrete structural design scheme is as follows:
This PVT relationship experiments special small oil pump, is directly provided with cock on its pump housing and seals valve, send oil interface and oil gauge interface.Cock seals and sets oil through, precession spiral and sealing ring pressing plate in the cock of valve.Accompanying drawing is this utility model structural representation.
Advantageous Effects of the present utility model is embodied in the following aspects:
1, the pump housing is directly provided with cock sealing valve, send oil interface and oil gauge interface, compact conformation, simple to operate；
2, once fill high-purity Oleum Ricini in pump chamber, under 5 DEG C to 40 DEG C room temperature conditions, adapt to experiment needs；
3, cock seal valve can opening and closing fluid passage more easily, its additional seal construction, adapt to high pressure requirement；
4, sending oil interface can directly dock pressue device, oil gauge interface can directly dock Pressure gauge, and reliability is higher；
5, this PVT relationship experiments special small oil pump, agrees with experimental apparatus miniature requirement, has good suitability.
Accompanying drawing illustrates:
Fig. 1 is the internal structure cross-sectional schematic of a kind of PVT relationship experiments special small oil pump.
Number in the figure illustrates: the pump housing--1, pump chamber--2, pump rod--3, end socket volution--4, cock--5, high-pressure seal ring--6, send oil interface--7, oil gauge interface--8 that seal valve.
Detailed description of the invention:
When the PVT relationship experiments instrument supporting with this special small oil pump totally assembles, the oil interface that send of this special small oil pump is docked with the oil-in of the hydrargyrum box on instrument.Necessary instrument is full of experimental gas by the oil gauge interface utilizing this oil pump, is then shut off the bottle valve on necessary instrument body；Hydrargyrum box is full of mercury solution by the oil gauge interface again through this oil pump, then opens bottle valve, is then filled by mercury solution to oil pump oil gauge interface along horizontal level, then installs oil gauge, closes the cock on the pump housing and seals valve；Fill up pump high-purity Oleum Ricini from pump chamber is suitable for reading again, finally install pump rod and end socket volution.Before experiment, after stable for supporting equipment placement, just open the cock on this pump body and seal the bottle valve on valve and necessary instrument body.During experiment, turn clockwise pump rod, it is achieved pressurization；Rotate pump rod counterclockwise, it is achieved release.When supporting experimental apparatus is as moved, it is necessary to the cock on Temporarily Closed bottle valve and this pump body seals valve, it is prevented that gas, hydrargyrum, oil conjugate because of vibration.
