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 is a constant velocity cylinder? What's the difference between a hydraulic cylinder and a hydraulic cylinder?: Upstairs said is the pressure cylinder, and a relationship between the landlord said nothing.

Q: Master, I want to make a set of hydraulic equipment for hydraulic piston and cylinder head with us how to adjust the tolerances. (H refers to the tolerance zone of the hole, f refers to the tolerance zone of the shaft, right? What does H7F8 mean?) I do not understand these written knowledge, it is best to say that the size of the piston head and cylinder bore how to fit, and can take specific figures for example, the best, the more detailed the better. To install the piston ring high speed heating will do, how to solve it, large caliber and long trip for us.: 2, the piston head and cylinder matching, in operation is to rely on oil sealing ring to seal the cylinder cavity.

Q: Is the hydraulic cylinder or pneumatic cylinder good, their respective advantages?: Cylinder: once in place, hydraulic cylinder: according to the needs of the lift, cylinder speed, hydraulic cylinder relative to the cylinder slower, gas compression ratio, liquid compression ratio is small.

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?: As hydraulic technology has many advantages, from civil to national defense, from general transmission to precision control, it has been widely used. In the mechanical industry, currently has 85% machine tool drive system adopts hydraulic transmission and control, such as grinding, milling, planing, pulling, and combined lathe; in engineering machinery, is widely used in hydraulic transmission, such as excavator, wheel loader, auto starter, bulldozer, scraper, grader, roller machine; in agricultural machinery, which has been used to combine harvester, tractor, tool suspension system; in the automotive industry, hydraulic brake, hydraulic dump, fire etc. are widely used; in the metallurgical industry, such as electric control system, rolling mill control system, charging, ing converter control, control of blast furnace;

Q: How to remove the hydraulic cylinder oil seal?: Is the O ring squeezed out? The front cover should be threaded, carefully to see if there are holes installed, there should be 2 or 4, is not to be painted over, if not, must use the flat shovel.

Q: Know how to clamp the hydraulic cylinder clamping force, clamping cylinder stroke, how to determine the type of clamping cylinder?: in the travel and travel, already know, so is the calculation of cylinder diameter: first by the clamping force and resistance, all losses on the cylinder at work and increase the safety coefficient, calculate the maximum thrust cylinder F; and then determine the pressure to choose the value P, calculate the piston area of A=F/P cylinder, finally converted a bore.

Q: Can the hydraulic jack be changed?: Yes, as long as the pressure of the air pump is large enough, of course, the pressure resistance of the hose should be good enough, and the speed problem can be solved by the reducing joint.Test method:1. remove the hydraulic jack refueling refueling Pusey, down on the square on the tin.2. release the hydraulic jack release valve and release the oil.3. remove the lift lever and use the +0 wrench. 8 meters of pipe clockwise unscrew the small pump, using a pointed nose pliers to pry open the gasket, remove the 6# ball.4. hydraulic jacks clamped in a vise, use pipe wrench will cap loosens counterclockwise, remove.5. beat the coat with a leather hammer and take it off.6. pull out piston rod, such as pulling out, put out the base with pointed nose pliers rectangular rubber ring valve hole, pour 8# ball, with a long stretch in the end mouth gun oil discharge valve seat hole inside the air, need to control the volume, the piston rod will pop up, aim at the wall, avoid injuries caused by pop-up.7. remove the nylon seal of the hydraulic jack piston and then put the piston rod back into the cylinder. Use the tubing to clamp the cylinder against the counter clockwise. Thus, when the pipe clamp is pulled on, the deformation of the oil cylinder can be avoided and the clamping flat can be avoided.8., with self tapping screws into the steel ball block, with pliers pull out the block, take out 6# steel ball.9. all parts of the hydraulic jack are cleaned with diesel oil and dried with an air gun. The holes in the base are blown with an air gun, and the inside of the cylinder is observed with a flashlight. Is the inner part of the pump smooth?. Replace it if it is not smooth or damaged. Observe whether the three steel balls are round and smooth.

Q: Hello, which units use hydraulic pneumatic cylinders and more cylinders?. Thank you: In short, the use of large cylinder, the use of re pressing machine, casting machine and other factories and mines, casting, steel, pipe, punch. These enterprises use more
