1. The use of six-face top hydraulic press:
Hexagonal hydraulic press is an ultra-high pressure equipment for synthesizing superhard materials. It is the main equipment widely used in China's superhard materials industry. The six-faceted hydraulic press developed and designed by Hanfa Group has safety and stability, simple operation, convenient maintenance, and significant economic benefits. Features. This equipment is mainly used for the production and research of superhard materials such as synthetic diamond, cubic boron nitride single crystal and polycrystalline, synthetic composite sheet (PCD.PCBN).
2. Six-side top cylinderless press:
Features: high precision, high stability, high economic efficiency. Disadvantages: The production technology of hinge beams is high, the design pressure is 110MP, and the working pressure is less than 85MP.
3. Types and characteristics of ultra-high pressure:
1. Supercharger overpressure The traditional overpressure form has advantages: low noise, low failure rate and super stability; disadvantages: large volume, high investment cost, and limited overpressure volume.
2. Ultra high pressure pump overpressure Advantages: simple structure, suitable for various technological forms. Disadvantages: high noise, high power, limited by the production quality of the pump. Configuration: 2-3 motors, motor power 5-20KW. (Appropriate adjustments will be made according to the cavity and process).
3. Overpressure of double-acting reciprocating supercharger Advantages: low noise, small size, convenient installation, suitable for various process forms. Disadvantages: unstable service life.
4. Advantages of flushing supercharger: small size, low noise, low failure rate, good stability, suitable for various process forms. Disadvantages: need a second pressure relief.
5. There are two commonly used overpressure methods:
a) Supercharger overpressure.
b) The ultra-high pressure pump is overpressured.
4.hydraulic system:
1. The composition of the hydraulic system
a. According to its oil circuit, it can be divided into main oil circuit and control oil circuit. The main oil circuit is bounded by an ultra-high pressure controllable one-way valve, which can be divided into two parts, high-pressure and ultra-high-pressure oil circuits. The high-pressure oil circuit is 10-28 (MPa), which is composed of an axial piston pump and general high-pressure hydraulic components. The ultra-high pressure oil circuit is composed of two-position seven-way valve, ultra-high pressure controllable one-way valve and ultra-high pressure one-way valve. The pressure of the ultra-high pressure oil circuit is below 120MPa.
b. According to its appearance, it is divided into the following 2 parts The ultra-high pressure part of the main engine: It is composed of an ultra-high pressure controllable one-way valve, an ultra-high pressure one-way valve and a two-position seven-way valve, and is connected to the six-side top host by an ultra-high pressure pipeline. High-pressure control part: consists of hydraulic station and power part. Developed according to changes in the ultra-high pressure part. Connect to the ultra-high pressure part by hose or steel pipe.
2. Features of hydraulic part Scientifically divide the hydraulic system to complete the off-site production of ultra-high pressure pipes. The whole machine can be installed with dual oil filtering systems to keep the oil circuit clean. The overall layout is neat. Normal production equipment management.
3. Hydraulic configuration Working pressure: ultra high pressure max 120MPa. System pressure max: The ultra-high pressure pump is configured to 12Mpa, and the supercharger is 15Mpa. Return pressure max: 5MPa (adjustable range 1.5-8MPa). Mainly equipped with power: (the plunger pump will be adjusted appropriately according to the size of the cylinder diameter). Plunger pump: 63/80 SCY14-1B supporting motor: 10-20KW; 10SCY14-1B supporting motor: 4Kw. Pressure relief method:
a. Proportional type: realizes three-stage unloading and meets the existing mainstream synthetic pressure relief requirements.
b. Curved type: also known as servo pressure relief, which can achieve arbitrary curve pressure relief and meet mainstream pressure relief requirements and special pressure relief requirements.
c. Compound type: comprehensive proportional and curved pressure relief, which basically meets all requirements of industrial synthetic pressure relief.
d. Gem-grade type: high-precision pressure relief, more in line with the synthetic process curve, and small pressure fluctuations.
Main valve diameter: 16 diameter of electro-hydraulic reversing valve, 10 diameter of electromagnetic reversing valve.
5. Electronic control system The main technical parameters
