Q: What does hydraulic cylinder type "HSG 80/60-1100" mean?: The complete specifications are as follows:HSG* cylinder head linkage mode -D/d* pressure level - mounting mode * piston rod mounting mode * with buffer * oil port connection type * stroke * mounting distance

Q: What are the characteristics of a piston hydraulic cylinder? How many kinds are there? What are they used for?If anyone knows, just say something: The hydraulic cylinder from the structure can be divided into the piston cylinder, piston cylinder and oscillating cylinder. The cylinder from the structure can be divided into the piston cylinder, pneumatic cylinder, telescopic cylinder hydraulic cylinder. The working principle is: as its principle I must first say 5 basic components, 1- and cylinder 2- cylinder piston and piston rod sealing device of 3- 4- buffer 5- exhaust device to work each cylinder is almost similar to the original, I took a manual jack is its original work, Jack is a simple cylinder. By manually pressurized straw (hydraulic manual pump) of the hydraulic the oil through a single valve into the cylinder, the hydraulic oil into the cylinder because the reasons for individual valve can not be returned back, forcing the cylinder rod upward, then work to continue to keep the hydraulic oil into the hydraulic cylinder continuously, thus increasing, hit when to drop Hydraulic valve, hydraulic oil back to tank. This is the most simple of the original work, others have improved on this basis, because of the time I would say the most simple principle. The advantages and disadvantages of the cylinder cylinder cylinder and the cylinder with almost I said the following 3 bit 1-- as the pneumatic system pressure is generally in the range of 0.2-1.0Mpa, so the cylinder is not bigger.

Q: What is the working pressure of the hydraulic cylinder with a diameter of 80?: I think you should ask about how much work you can do at work. Formula: theoretical output = work pressure x piston area. The piston area 80 cylinder diameter is 3.14*40*40=5026mm^2; if the work pressure is 10MPa; then the theoretical output is 5026x10=50260N, equivalent to 5 tons of force.

Q: What are the conditions in the hydraulic system with the imported throttle valve? What is the difference between the throttle valve and the outlet valve?: 2., import throttle speed control, easy to use pressure relay to achieve pressure control;

Q: What should be considered when the hydraulic pressure is changed and the pressure is changed? Is the cost of air pressure high relative to hydraulic pressure?: This change has to be premise, there are many functions can not be replaced. Hydraulic is characterized by "incompressible" and can be "precise control."". The compressibility of the air is unstable, and the end of the movement is the full stroke of the cylinder, while the hydraulic pressure is random. This is in "accurate, safe" on the big difference, depending on your working conditions are there such requirements?

Q: Does the car have no cylinder pressure? Is it related to the hydraulic bottom support?: There is no cylinder pressure for more reasons, the general cylinder internal cylinder sleeve, piston, piston ring and valve wear and timing, hydraulic systems, pressure relief, etc., need to be checked in order to confirm the cause of the failure

Q: Is the hydraulic cylinder or pneumatic cylinder good, their respective advantages?: Each has its advantages!Hydraulic relatively speaking, the production is more stringent!The air is relatively clean, because the medium is filtered air!

Q: Why is the digital hydraulic cylinder not widely used?: 2, hydraulic system plus flow flow valve; 3, do synchronous cylinder.

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: 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
