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 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.

Q: What is a constant velocity cylinder? What's the difference between a hydraulic cylinder and a hydraulic cylinder?: The cylinder piston rod extends out should be constant and consistent back speed cylinder called isokinetic cylinder. The difference between it and ordinary hydraulic cylinder hydraulic cylinder is common only a head with a piston rod extends out of the general slow recovery fast, because the relationship between the effective area of the piston cavity.

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.: 2, the piston head and cylinder matching, in operation is to rely on oil sealing ring to seal the cylinder cavity.

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: Hydraulic principle: A typical hydraulic system comprises a hydraulic pump, hydraulic oil tank, directional control valve, flow control valve, the working cylinder, plunger valve and pressure relief valve. Three kinds of typical hydraulic pump hydraulic system used in gear pump, vane pump and axial reciprocating pump. Pump is the power component liquid system is the heart of the hydraulic pump control element. (including the flow valve, relief valve, directional valve and proportional valve etc.) for controlling and regulating the fluid pressure. The flow and direction, to meet the performance requirements of equipments, and the realization of various work cycle, the implementation of components to the pressure of the liquid can be converted to mechanical energy, so as to drive the movement of the mechanism.

Q: After running in, the upper cylinder head, the hydraulic jacking rod and the rocker arm are also arranged in the original position, and the cylinder head is not provided with a valve body without gaps: I. valve clearance: when the valve is completely closed, the gap between the end of the valve stem and the component of the valve train is called the valve clearance. Two, the valve clearance is necessary: when the engine works, the valve will be due to temperature expansion, if the valve and its transmission parts, in the cold when no gap or clearance is too small, in the hot state, and the transmission of the thermal expansion valve will cause the valve is not tightly closed, causing the engine leakage in the power stroke in compression and the power down, don't even start easily when serious. In order to eliminate this phenomenon, the valve clearance is usually used in the cold assembly of the engine to compensate for the expansion after the valve is heated. Some engines use hydraulic tappet, the length of tappet can change automatically, and the thermal expansion of the valve is compensated at any time, so there is no need to reserve the valve clearance. Three, the valve clearance is too large and too small damage, the size of the valve clearance by the engine manufacturer, according to the test to determine. Generally in cold state, the clearance of intake valve is 0.25mm~0.35mm, and the clearance of exhaust valve is 0.30mm~0.35mm. 1, too small: if the valve clearance is too small, the engine in hot state may be due to valve closed lax and leak, leading to power down, or even valve burned.

Q: What's the difference between an electric hydraulic and a pneumatic jack?: The two are the same: the executing agencies are hydraulic piston rod. The difference between the two is: electric hydraulic motor drives the oil pump, so that oil into the hydraulic cylinder, push the piston rod to work. Pneumatic hydraulic jack is two cylinder: the smaller cross-sectional area of the cylinder and the area of the cylinder when the cylinder gas of large capacity into small capacity, will produce several times, even ten times of pressure on the small cylinder, the output of small cylinder piston rod increases greatly, this method is called "liquid booster". Also called the cylinder pressure cylinder.

Q: Apart from the way they are installed, are their sensors universal? That is, can the induction switches used on the A model cylinder be used on the B model cylinders?!Some cylinders use large ones, but others are very small. Are they interchangeable? That is, if the big induction switch is broken, can it be replaced with a small one?: Are you talking about the magnetic induction switch, only the cylinder with magnetic band can be used?
