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:used as the form of a connecting rod or piston in an automobile crankshaft. What is the minimum allowable value for such a hydraulic cylinder?. This way, the supply of oil cylinder in the rear, I ask the output cylinder allowed the maximum number of transfer, such as cooling good, the highest output can be transferred. How many manufacturers are there in the market?.

Spinning speed, no speed. Why do you have to do this? Why don't you just use a hydraulic motor directly?

Q:How much is the 1000 ton hydraulic cylinder

The rated working pressure of general press is 25MpaUsually made of 700mm large diameter (the actual calculated is about 715)

Q:Solenoid valve, cylinder should use VG32 turbine oil, I use 46# hydraulic oil instead?

No, VG32 turbo oil works well. 46# hydraulic oil causes viscosity in use and affects the operation of pneumatic components.

Q: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?

Q:Can you tell me if the cylinder can be changed into an oil cylinder (low pressure)?

Yes, as long as your oil pressure is below 8KG on the line, but it is difficult to get such oil pressure, the general pressure of the pump above 70KG, if filled into the cylinder, it will burst.

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: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:Is the hydraulic cylinder at rated pressure the greater the stroke and the greater the pressure, is there a formula?

The greater the diameter of the cylinder and the larger the area, the greater the pressure it can get.Thrust calculation formula of hydraulic cylinderThrust: 3.14 x 2 x (- / 2 / 1000) of hydraulic pressure

Q:always have hydraulic oil leakage, please expert advice, with what seal can avoid, the best zero leakage.

200 / min work frequency, high viscosity, slow flow, affect operation sensitivity.It is precisely the year that is too low to cause disclosure. Try to increase viscosity properly.This is a contradiction.
