Hydraulic Cylinder Description
Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating movement (or swinging movement). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The hydraulic cylinder is basically composed of cylinder and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
Pressure Dependent Control
Classification and graphic symbols of commonly used hydraulic cylinders, structure and characteristics of typical hydraulic cylinders, piston hydraulic cylinders, plunger hydraulic cylinders, retractable hydraulic cylinders, rotary hydraulic cylinders, oscillating hydraulic cylinders, combined hydraulic cylinders, electro-hydraulic stepping hydraulic cylinders, hydraulic oil, hydraulic cylinder oil pollution control synthesis cavity expansion, The pressure difference between the shell and the core of the composite rod, that is, the pressure gradient of the pressure field, will be increased because of the pressure transfer loss. At the same time, the growth process of diamond also causes the change of pressure field.
As we all know, at high temperature and high pressure, the process of converting graphite to diamond with pyrophyllite as the pressure transfer medium includes a series of phase transformation processes: pyrophyllite mineral phase transformation produces cyanite, corzine and graphite phase transformation produces diamond. Due to the significant ratio of these phase transitions, the volume contraction before and after the phase transformation results in the pressure drop inside the synthetic cavity; Moreover, pyrophyllite is rigid due to the increase of friction coefficient and strength after the phase transition, which affects the effect of pressure transfer and pressure reinforcement, which results in a greater pressure gradient in the cavity, and the growth of high-quality diamond single crystals requires relatively stable pressure conditions, so how to better reduce the pressure gradient is the challenge facing the large-cavity process.
1) The pressure boost curve is controllable, which can effectively control the pressure gradient with the heating curve
2) The pressure curve increases in the holding stage, reducing the increase in pressure transfer gradient caused by the synthetic phase transition
3) The pressure relief speed is controllable, taking into account the different requirements of the pressure relief speed when high and low pressure, the principle of the proportional valve is to control the current or voltage according to the set curve, so as to control the thrust and displacement of the proportional solenoid continuously in proportion to achieve the purpose of controlling the pressure and flow of the system. The proportional pressure valve or proportional pump in the system can not only realize the continuous increase of system pressure in the pressure holding stage, but also realize the continuous control of the pressure boost speed in the pressure boost stage, that is, the full curve control of pressure is realized. Arguably, this is the most likely approach to the ideal control mode.
