Q:What are the characteristics of the cylinder compared with the hydraulic cylinder?

Low pressure cylinder bore the same, but the working environment is clean, the hydraulic cylinder oil leakage problem

Q:How is the hydraulic jack refitted into a high pressure inflator?

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:What is the bad effect of the engine oil pressure on the engine when the oil pressure is too high or too low?

The pressure is too high, the hydraulic tappet internal rigidity is too large, it is easy to cause its door closed tight and so on, the pressure is too low, the hydraulic tappet internal rigidity is too small, will cause the valve clearance is too big. And aggravate wear. Note that this is only a one-sided phenomenon. In fact, when the oil pressure is unstable, the hydraulic tappet itself can compensate for the lack of pressure. I hope the above answer will help you.

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:Is the cylinder usually faster than the hydraulic cylinder?

When the compressed air flow is the same as that of the hydraulic source, the speed of the cylinder and the hydraulic cylinder are the sameIn actual use, the general air compressor low pressure air compressor driven by the same motor power output than hydraulic machine, so the result of the action of hydraulic cylinder cylinder than subconsciously think fast.

Q:This is the model of a hydraulic buffer tank used on an oil rig. Who can explain the meaning of this model to me, especially the meaning of 550*905, and also provide the best drawings

HSG--- double acting single piston hydraulic cylinder, piston type K--- card key, 01--- for the Y type sealing ring, 160/110E--- bore diameter is 110, 160, a pressure of 16MPa, 5221---5 said the cylinder head or cylinder middle flange connection, 2 piston rod end thread, 2 (second 2) the cylinder head end buffer 1 oil port internal thread; 550 stroke, 905 for the minimum installation distance.

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

The difference is that the pendulum shear is the return cylinder of the nitrogen return cylinder!

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.

if you want to change into the cylinder pressure, enough on the line, in addition to consider increasing the oil return pipe of the cylinder, pneumatic actuator only because the system did not return with an air inlet pipe. The trachea.

Q:Why is the digital hydraulic cylinder not widely used?

4, servo control system.Several of these are for reference only.A hydraulic cylinder is a hydraulic actuator that transforms hydraulic energy into mechanical energy and makes linear reciprocating motion (or swinging motion).The utility model has the advantages of simple structure and reliable work.

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

High pressure and high speed will result in high temperature at the sealing place. The sealing wear and aging will be very quick, even if the trial production effect is ideal, the actual use will be a problem.Increase the surface finish and hardness of piston rodImprove the wear resistance of sealing material at high temperatureIncrease seal quantity, multi stage seal
