Abstract

The utility model relates to a high-pressure forming and retaining mechanism of a press, which belongs to the technical field of diamond synthesis equipment. The utility model comprises an oil tank, an oil pump, an oil circuit control valve plate and a high pressure cylinder, which are orderly communicated through a pipe, wherein the oil pump is a high-pressure pump which is composed of mass flow excess pressure pump and a small flow pressure compensating pump, which are coordinate. The flow capacity of the mass flow excess pressure pump is 6-30 litre / minute, and the flow capacity of the small flow pressure compensating pump is 1-10 litre / minute. The stable high voltage state of a piston cylinder of the press can be rapidly realized and kept by the utility model.

Description

Press high-pressure forms and maintaining body
Technical field
The utility model belongs to diamond synthesis device technical field, and the super-pressure working cylinder high pressure in particularly a kind of cubic hinge press synthesis device forms and maintaining body.
Background technology
The high pressure of the super-pressure working cylinder in the cubic hinge press synthesis device is set up most important, and the stability of its pressure is also very crucial.The production process time of high grade diamond is long, requires pressure stability.But in the diamond film process, because changes in environmental conditions, and adamantine transformation, the seal leakage of super-pressure synthetic cavity, the actual pressure and the temperature of synthetic cavity constantly reduce, so its ftercompction and heating must be constantly given in requirement.Press high-pressure forms mechanism's (see figure 1) and is made up of fuel tank 1, oil pump 2, oil passage control valve plate 3, oil circuit booster 4 and the high pressure cylinder 5 by pipeline connection successively in the old-fashioned press system, wherein oil pump 2 is the common oil pump of driven by motor, reaches the high pressure conditions of piston cylinder 5 by the proportional increase of the pressure of booster 4.Yet the piston stroke of booster is limited, and piston is behind the top, and the supercharging activity just stops, owing to do not reach the high pressure conditions that needs, diamond production can't be carried out, and can't satisfy the synthesis technique requirement.
The utility model content
The utility model purpose is to provide a kind of and is convenient to realize that the press high-pressure of press piston cylinder stable high voltage state forms and maintaining body.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: press high-pressure forms and maintaining body, comprise that successively by fuel tank, oil pump, oil passage control valve plate, the high pressure cylinder of pipeline connection, oil pump is a high-pressure pump, is made up of big flow excess pressure pump arranged side by side and low discharge ftercompction pump.
Big flow excess pressure pump flow be the 6-30 liter/minute, low discharge ftercompction pump discharge be the 1-10 liter/minute.
The utility model forms mechanism to existing press high-pressure and improves, removed existing press high-pressure and formed oil circuit booster in the mechanism, cashing has press high-pressure to form that common oil pump is two high-pressure oil pumps parallel with one another (big flow excess pressure pump arranged side by side and low discharge ftercompction pumps) in the mechanism.Superpressure adopts large-flow high-pressure pump (flow 6-30 liter/per minute is decided on the press size) first, can reach high pressure conditions fast, increases work efficiency; Ftercompction work in the pressure maintaining period is selected for use than low discharge ftercompction pump (flow 1-10 liter/per minute is decided on the press size), and supplementary pressure can not cause the system pressure fluctuation fast, and it is stable to keep-up pressure.The utility model great advantage is a superpressure indefinitely, and the superpressure that does not resemble old-fashioned press is subjected to the travel limits of booster.
Description of drawings
Fig. 1 forms the mechanism structure schematic diagram for existing press high-pressure;
Fig. 2 is the utility model structural representation.
The specific embodiment
As shown in Figure 2, press high-pressure forms and maintaining body comprises fuel tank 1, oil pump, oil passage control valve plate 3, the high pressure cylinder 5 that passes through pipeline connection successively, and oil pump is a high-pressure pump, is made up of big flow excess pressure pump 2-1 arranged side by side and low discharge ftercompction pump 2-2.Big flow excess pressure pump 2-1 flow be the 6-30 liter/minute, low discharge ftercompction pump 2-2 flow be the 1-10 liter/minute.6 is motor.

Claims (2)

1, press high-pressure forms and maintaining body, comprises successively it is characterized in that by fuel tank, oil pump, oil passage control valve plate, the high pressure cylinder of pipeline connection oil pump is a high-pressure pump, is made up of big flow excess pressure pump arranged side by side and low discharge ftercompction pump.
2, press high-pressure as claimed in claim 1 forms and maintaining body, it is characterized in that, big flow excess pressure pump flow be the 6-30 liter/minute, low discharge ftercompction pump discharge be the 1-10 liter/minute.
