The main difference between hydraulic circuit and pneumatic circuit
The hydraulic movement position is accurate, the barometric pressure because the compression movement is inaccurate, the hydraulic pressure general movement is slower, the barometric pressure is quicker. Hydraulic power source is generally hydraulic pump, pressure source is generally compressor. Hydraulic force is greater, the pressure is relatively small.
What is the pivot shaft in the cylinder?
1. Welding with high strength WE600 welding rod.2, WE600 is a low heat output, suitable for special nickel chromium alloy steel electrode welded all-round, universal design is extremely wide, the general strength of parent materials with high strength, excellent welding performance, stable arc, beautiful shape of seam, in oil, water and rust conditions can welding effect is excellent, can the welding of different steel.
What are the conditions in the hydraulic system with the imported throttle valve? What is the difference between the throttle valve and the outlet valve?
2., import throttle speed control, easy to use pressure relay to achieve pressure control;
What are the components of the cylinder and the hydraulic cylinder?
Hello, are you asking about the cylinders and cylinders? Cylinder barrel, upper and lower end cover, pull rod, sealing ring and so on. I am a professional, do this, what problems can continue to ask me?
What's the name of this hydraulic device? Where can I buy it?!
The black one doesn't tell whether it's a cylinder or a hydraulic cylinder.
For example, I press a workpiece with a hydraulic press, and the pressure gauge shows 0.3MPa. Then I change the cylinder pressure. When I type, I choose the 0.3MPa cylinder instead of the inner diameter of the cylinder.
To see the pressure gauge is arranged in what position, the general pressure gauge installed in the hydraulic station exit, that is the pressure of the hydraulic system;
What is the four link mechanism of hydraulic support?
Four link mechanism is an important part of hydraulic support, including: connecting rod, rear connecting rod, shield beam and base.1. The connecting rod group consists of the connecting rod body, the connecting rod big head cover, the connecting rod small head bushing, the connecting rod big head bearing bush and the connecting rod bolt (or screw). The connecting rod group bears the force acting on the piston pin and its swing and the reciprocating inertia force of the piston group, and the magnitude and direction of these forces are periodically changed. Therefore, the connecting rod is subjected to alternating load such as compression and tension.
What are the characteristics of a piston hydraulic cylinder? How many kinds are there? What are they used for?If anyone knows, just say something
The power of dynamic components of hydraulic cylinder can be relatively large power components, the use of hydraulic system, the 2-- from the medium air is inexhaustible, no cost and supply difficulties, the gas used directly into the atmosphere, convenient. The hydraulic oil in the air, 3-- small viscosity, resistance is less than 4-- but the compression rate of air hydraulic oil is far greater than the hydraulic oil so it work smoothly and in order to better response sent greater output Torque, it is necessary to use the volume. Compared to swing vane motor. Many gear rack swing hydraulic cylinder. The torque is generated and transmitted by a driving gear is provided with a rack piston shaft lateral position achieved. According to the design, roller bearings, hydraulic balance or prop up the shear counterproductive gear tooth and the piston. The principle of swinging cylinder reciprocating movement of the hydraulic cylinder is driven by gear rack, the gear shaft is converted into reverse swing rotation, while the reciprocating cylinder thrust into the output torque of the gear shaft. The gear shaft is proportional to the swing angle and the length of the rack, so the gear shaft swing the angle can be arbitrarily selected, and greater than 360 degrees.
