Q: Can the hydraulic cylinder change the nitrogen cylinder?: This estimate is not, first consider the seal hydraulic oil cylinder and the air cylinder design according to different media, sealing is certainly not the same, if the hydraulic oil cylinder into the cylinder may be sealed and lax circumstance.

Q: The 80 hydraulic cylinder is equivalent to the pressure of the larger cylinder: It depends on how much you supply the hydraulic system hydraulic cylinder pressure, there is a gas path set pressure output size of the cylinder, when the hydraulic system pressure is 100kg/cm2 80mm oil output is 5 tons, the pressure when the system pressure is 5kg/cm2 then the cylinder bore 360mm can output 5 tons

Q: Is it possible to change the hydraulic cylinder of the hydraulic lifting platform to the cylinder?: Certainly not, unit pressure varies greatly, not applicable

Q: 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.

Q: What are the acceptance criteria for hydraulic cylinders?: China has published the hydraulic cylinder of the ISO standard (excluding seal standard 6), there are more than 20, as follows: ISO3320-75 hydraulic and pneumatic systems and components of a cylinder diameter and piston rod diameter of a ISO3321-75 metric series of hydraulic and pneumatic systems and components of a cylinder bore and piston rod diameter ISO3322-75 Inch series of hydraulic and pneumatic systems and components of a cylinder of a nominal pressure ISO4393-78 of hydraulic and pneumatic systems and components with a cylinder and a piston stroke basic pressure ISO4394-78 hydraulic and pneumatic systems and components of a cylinder diameter steel pipe processing conditions of ISO4395-78 hydraulic and pneumatic systems and components of a cylinder and a piston rod thread size ISO5597/1-80 type of hydraulic cylinder piston rod and a piston reciprocating sealing groove: Nominal dimensions and tolerances of 1 series ISO6020/1-81 -160bar series hydraulic single rod hydraulic cylinder - Mounting dimensions

Q: Is the hydraulic cylinder or pneumatic cylinder good, their respective advantages?: Operating pressure: the maximum working pressure of the hydraulic cylinder can be up to more than 20 MPa and the cylinder is 1 MPa High, usually at 0.5-0.6 mpa. In other words, the same size cylinder hydraulic output to 20 times the cylinder.Power source: the hydraulic cylinder needs pumping station to provide high pressure oil; the cylinder needs the air source; if not, use the air compressor.Speed: the hydraulic cylinder is slower than the cylinder, and is more stable than the cylinder. Cylinder speed can not be too low (such as a few millimeters per second), otherwise it will crawl.Environment: the hydraulic system will inevitably leak, relatively dirty; pneumatic system is very clean; hydraulic pump noise; pneumatic; air source, the noise is very small; with air compressor, the noise is greater than the hydraulic pump.Cost: pneumatic much cheaperIn addition, if the pressure is high (12 tons), the process is not large (about 100mm), there is a compressed air source, it needs clean environment, low noise, low cost, you can use the gas-liquid booster cylinder.

Q: The surface of the hydraulic rod is chromium, and it often causes strain, scratch, electric shock and so on. The routine method is slow to repair and the effect is not satisfactory. Don't want to play with copper, also do not want to use cold, patch method, because of poor adhesion, never long broken. Is there a better way to fix it?: Brush plating method to repair hydraulic rod, cylinder pull, the best effect. Because the 1. can be repaired on the spot, the trouble of loading and transporting is avoided. 2., coating adhesion is good, no obvious boundaries, repair surface hardness, good wear resistance. 3. low temperature operation will not change the properties of the substrate. Electroplating repair technology is a kind of traditional repair technology to restore the size of parts at low temperature.

Q: What is it used for? What kind of factory is likely to be used in general?: Hydraulic equipment, cylinders, cylinders are used in the principle of hydraulic transmission power, in particular, low aerodynamic pressure, hydraulic high. At the same time, the environment

Q: In hydraulic knowledge, the working principle of pneumatic triple parts: Pneumatic tool with: 1, can be used in explosive, corrosive, high temperature and damp environment; 2, overload operation without causing motor burned; 3, simple structure, durable, relatively easy to maintain; 4, large output torque, light weight and high efficiency; 5. Stepless speed regulation, and can produce a rotating, reciprocating movement and impact; and other advantages, and is widely used in the modern machinery manufacturing, shipbuilding, automobile manufacturing and other fields, especially in automobile manufacturing, grinding, polishing, spraying, assembly and other conditions are widely used in the production process, is a modern the automobile industry is an indispensable important batch of large-scale production equipment, but because in the automobile manufacturing industry, nearly 90% of the vehicle assembly connection through a screw thread, so pneumatic tightening tools in the whole It is widely used in vehicle assembly. Broadly speaking, pneumatic tool is the use of compressed air motor to output kinetic energy work on a tool with the general pneumatic tool mainly comprises a power output part, operation part, transformed into the exhaust path, open and stop operation control part, the main part of a tool, of course, pneumatic operation tools must also have the energy supply part, air filter and pressure regulating part and tool accessories etc..

Q: Difference between cylinders of hydraulic cylinders: The working principle is very simple by using the Pascal principle (F1/A1=F2/A2), the advantages do not need lubricating oil, because his work is medium, and he can realize remote control, can realize stepless speed, no noise etc......
