Q:What is the basic working principle of the cushion device in the hydraulic cylinder?: such as cylinder movement to the stroke switch, switch signal, cut or limit the flow of hydraulic oil into the cylinder, the cylinder movement slowed down, and ultimately by the buffer cylinder buffer. I hope to help you!

Q:2. To make the piston move at 5m/min, what is the flow rate of the input cylinder L/min?: What's the program for a cylinder? It won't be 5MQ=AV/SQ flow, A area, V speed, S travel timeSet the time to 1 minutesO=1962.5*10^-6 (M^2) * 5 (m/min) *I=9812.5*10^-6 (m^3/min) =9.825*L/min

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?: 1. pairs of single rod hydraulic cylinder, import throttle speed into the non rod cavity, you can get more speed than the oil back throttling speed

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:What is pneumatic oil? Is it the same as hydraulic oil?: Pneumatic and hydraulic oils are not oils. Pneumatic lubricants require high oxidation resistance and lubricity, while hydraulic oils require good abrasion resistance, oxidation resistance, lubricity and foam resistance as well as anti emulsification effects. Pneumatic lubricants are generally thinner than hydraulic oils.

Q:Application of pneumatic hydraulic pump: 2 aerospace industry;1) hydraulic pumping station is used for hydraulic lifting device;2) perform pressure tests (fittings, valves, fittings);3) gas drive power station is used in hydraulic emergency system;4) high pressure air source device;

Q:Can you tell me if the cylinder can be changed into an oil cylinder (low pressure)?: Impossible, otherwise, the volume is not the same.

Q:Computer automatic packing machine, cylinder voice suddenly become larger, how to solve?: 3 there is no hydraulic oil in the hydraulic cylinder;4, there is no residual air in the hydraulic cylinder, which makes the hydraulic cylinder unstable and crawlingAlso is the likely cause of scuffing, don't move, check it apart

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?: Consider 1, after the replacement function can meet the use requirements,2, after the replacement of equipment, there is still room for change.3, cost and replacement engineering difficulty4, the use and maintenance after replacement.5, environmental protection, mainly noise,

Q:We have to design a manual plunger water hydraulic pump, but the wall thickness of the cylinder will not be designed and checked. I follow the sigma delta is not less than PD/2[design is out of 10mm thick, but the teacher said 5mm can withstand the pressure of 150MPa, the material with corrosion resistant stainless steel can. Some of my parameters are the maximum cylinder pressure 140MPa, cylinder size d=18mm (can also be smaller), length 60 ~ 80mm, how can I design wall thickness? thank you very much indeed: The maximum permissible bearing pressure in the thin-walled tube [P] formula: [P]] =2[sigma phi S (D / S) in the formula: [Sigma - material allowable stress; coefficient of weld - diameter, seamless tube, pipe wall thickness with =1; S-- d--; the inner diameter of the pipe.
