Q:Does the car have no cylinder pressure? Is it related to the hydraulic bottom support?

It has something to do with the tight seal of the cylinder, where the valve is hung or burned

Q:Pneumatic cylinder stem can replace pneumatic hydraulic jacking rod. Who is big?

As a result, the thrust of the hydraulic rod is about 10 times greater than the thrust of the pneumatic rod. The difference between the two is too large, so they are on the use of strength, pressure performance, manufacturing materials, especially thrust, are very different. Therefore, the top rod of the pneumatic cylinder piston rod can not replace the top rod of the piston rod of the hydraulic 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?.

Yes, but this requirement is very high, and the input power is also greater. I don't know what you do

Q:Hydraulic oil? Refrigerant? Brake night? What are they? What's the function of it?

Cooling liquid is used for automobile engine cooling, winter antifreeze, corrosion protection, waterproof scaleLubricating fluid is oil and gear oil, such as ease the friction between the piston and the cylinder wall in the engine

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: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: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!

May not！ The structure is about the same, but there are many differences, such as: internal combustion cylinder rings, and cylinder Oring.

Q:I would like to ask if the speed of the hydraulic cylinder is related to the load on the piston rod?Proportional flow valve how to type, I currently only know the maximum pressure 2.5Mpa, according to Q=VA count as 0.4L/min, 1L/min can be chosen according to the ratio of flow valve? Is there another way to choose?

In the normal working pressure range, the speed of the hydraulic cylinder is independent of the load. The speed decreases only when the load is abnormal or near the variable pump setting pressure, forcing the system pressure up to the system overflow valve, overflow, or variable pump variables.

Q:What is the working pressure of the hydraulic cylinder with a diameter of 80?

See how you use it.. Let's do this

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.
