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?

Compared with welding repair technology, the problems of local high temperature will not occur. Electroplating repair technology is the use of electrolysis principle, the bath metal ions reduced to metal atoms, and deposited on the metal surface, forming a high binding force and a certain thickness of the repair layer.

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:How much is the 1000 ton hydraulic cylinder

Here the hydraulic diameter is 700mm. Hydraulic machine rated working pressure is 25Mpa, usually made of 700mm large diameter (the actual calculated is about 715).Bore: bore is the diameter of the cylinder, stroke (stroke) is the movement of the piston stroke BDC and TDC distance.Example: a car reciprocating engine, diameter 80 mm, 90 mm stroke, 4 cylinder. Single cylinder displacement calculationBore 80 mm / 2= radius of 40 mm and 40 mm * 3.14x90=452160 cubic square.

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:What is the difference between the cylinder seal and the cylinder seal?

The medium of bees is different. One is gas sealed, and the other is liquid sealed.

Q:Because I want to get a method to start the internal combustion cylinder (but not the cylinder cylinder, hydraulic cylinder like that, what I need is moving forward rather than rotating), but I have been unable to find this kind of cylinder, so would like to ask you that there is no real cylinder if there is? And can you tell me? If not, can the general cylinder and hydraulic cylinder internal combustion use? But I'm afraid of the inside of the rubber objects such as heat...Thank you!

Sorry, I don't know much about it! I can't help you!!

Q:machinery and components, such as cylinders, cylinders and so on, whether the pressure vessel ah? Does the relevant manufacturer need relevant qualifications? FiveThere are two entirely different answers to the question. Which one is right? Hope that professionals pointing. Thank you

In hydraulic and pneumatic equipment, only the gas tank and accumulator belong to the pressure vessel and require qualification. The remaining electromagnetic valves, cylinders and cylinders do not belong to the pressure vessel

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:What is pneumatic oil? Is it the same as hydraulic oil?

The main function of pneumatic lubricating oil is to lubricate, and the main function of hydraulic oil is to transmit pressure, and the two can not be mixed

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?
