Q: The difference between cylinder and hydraulic cylinder: At the same weight, the cylinder is heavier than the cylinder,In the form of output, the output load of the cylinder is relatively light, and the load of the hydraulic cylinder is heavy load,

Q: 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.: No, you want the workpiece to be the force, and the pressure gauge shows the pressure. F=PXS. If ventilation occurs, the cylinder bore and air pressure need to be recalculated.

Q: How do I calculate the flow rate of the hydraulic cylinder?: Hydraulic cylinder flow = hydraulic cylinder piston cross section * speedFor example: the cylinder speed of D10cm requires 10cm per secondThe hydraulic cylinder piston cross-section =pi * D * D, 4=3.14 * 10 * 10 4=78.5 / cm2Flow per second =78.5 * 10=785 ml =0.785 litersThe flow rate is =0.785 * 60=47.1 liters per minute

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,

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 hydraulic cylinder from the structure can be divided into the piston cylinder, piston cylinder and oscillating cylinder. The cylinder from the structure can be divided into the piston cylinder, pneumatic cylinder, telescopic cylinder hydraulic cylinder. The working principle is: as its principle I must first say 5 basic components, 1- and cylinder 2- cylinder piston and piston rod sealing device of 3- 4- buffer 5- exhaust device to work each cylinder is almost similar to the original, I took a manual jack is its original work, Jack is a simple cylinder. By manually pressurized straw (hydraulic manual pump) of the hydraulic the oil through a single valve into the cylinder, the hydraulic oil into the cylinder because the reasons for individual valve can not be returned back, forcing the cylinder rod upward, then work to continue to keep the hydraulic oil into the hydraulic cylinder continuously, thus increasing, hit when to drop Hydraulic valve, hydraulic oil back to tank. This is the most simple of the original work, others have improved on this basis, because of the time I would say the most simple principle. The advantages and disadvantages of the cylinder cylinder cylinder and the cylinder with almost I said the following 3 bit 1-- as the pneumatic system pressure is generally in the range of 0.2-1.0Mpa, so the cylinder is not bigger.

Q: press the stroke 3CM, and then use the shearing machine as nitrogen cylinder return stroke, and then press down again 3CM.Consult you, 300 tons of hydraulic cylinder pressure, 28 MPa downward pressure stroke 3CM, and then use a shear plate as nitrogen cylinder return, and then press down again 3CM. 40 times per minute, OK? Is it feasible to do so?I would like to refer to the principle of shearing machine, to do a 3CM stroke 300 tons hydraulic press. Is that feasible? Since I need a very short stroke, I would like to use an ordinary larger cylinder instead of a fast cylinder. The return trip would also like to use nitrogen, which would make the hydraulic part the simplest, not knowing whether I was right or not: Both pendulum shearing machine and gate shearing machine adopt single acting hydraulic cylinder! Jianhu Huabo hydraulic guillotine shears is accumulator return

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.: 3, if not the special equipment, hydraulic system piston will not have high speed movement, it is by slow extrusion oil, and obtain greater impetus. But internal combustion engines are exceptional.4, the hydraulic system and the force is proportional to the size of the bore, the good solution. However, long stroke (such as ten meters) to consider the rod out of such a long deflection problem, is a key consideration.

Q: What is the cold drawn cylinder of a hydraulic cylinder? How about his quality? Master, help! Thank you: Is the map in 4, the main advantages of the cold drawn pipe is the inner and outer dimension precision (tolerance) strictly, and surface roughness, roundness, straightness, uniform wall thickness, our company specializing in the production of hydraulic cylinder, the cylinder and the cylinder, the piston rod and its accessories, high quality and low price, welcome to buy

Q: We have to design a manual plunger water hydraulic pump, but the wall thickness of the cylinder will not be designed and checked. I follow the sigma delta is not less than PD/2[design is out of 10mm thick, but the teacher said 5mm can withstand the pressure of 150MPa, the material with corrosion resistant stainless steel can. Some of my parameters are the maximum cylinder pressure 140MPa, cylinder size d=18mm (can also be smaller), length 60 ~ 80mm, how can I design wall thickness? thank you very much indeed: The maximum permissible bearing pressure in the thin-walled tube [P] formula: [P]] =2[sigma phi S (D / S) in the formula: [Sigma - material allowable stress; coefficient of weld - diameter, seamless tube, pipe wall thickness with =1; S-- d--; the inner diameter of the pipe.

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......
