Q: 2. To make the piston move at 5m/min, what is the flow rate of the input cylinder L/min?: The flow is equal to the cross sectional area multiplied by the flow velocity,The flow rate in the problem is the piston movement speed, 5m/minThe area is 0.5 square decimeter decimeter, the flow rate was 50 per minute,So the flow is 25L/min

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: Solenoid valve, cylinder should use VG32 turbine oil, I use 46# hydraulic oil instead?: No, VG32 turbo oil works well. 46# hydraulic oil causes viscosity in use and affects the operation of pneumatic components.

Q: How do you adjust the timing of the car's cylinder?: If there is a distributor. You can rotate around to make time earlier or later. If not, start with the timing belt, one earlier or later! To adjust the time!

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: The main difference between hydraulic circuit and pneumatic circuit: I. pneumatic basic circuit is the basic component of pneumatic circuit, and complex pneumatic operation system is composed of one or more basic circuits. Compared with hydraulic, pneumatic circuit has its own characteristics:1, an air compressor can simultaneously supply gas to multiple circuits, while hydraulic pumps generally provide only one loop.2. The compressed air will be discharged into the atmosphere directly after the end of the cycle. No hydraulic drive will be necessary to recover the oil into the tank.3, air senior lubrication performance is poor, need additional oil supply device.Two, through the introduction of the previous articles, we generally understand the hydraulic circuit and the use of pneumatic circuit, as well as related presentations, and then we will explore how the cylinder should be chosen.Standard cylinder selection process is generally based on the needs of the job to determine the type of cylinder, installation forms, working pressure, cylinder and stroke, cylinder standard series and product samples for selection, gymnastics as;1, the cylinder output size of the load by 1.15~2 times to select, and accordingly determine the cylinder bore.2, according to the implementation of the agency's travel requirements to determine the cylinder piston stroke length, usually need to leave the margin of 5-20mm.3, according to the speed of the piston movement, select the appropriate inlet diameter, the greater the value, the faster the speed. In order to make the speed steady, a cylinder with a buffer device can be used.

Q: There is oil in the tank. Is it the cylinder gasket? Some people say that the serious thing is the cylinder block cracking, I would like to know the excavator cylinder block under what conditions will crack the body? It's not cold, not frozen!!: What you say is possible, the steel mat will be, the steel body will also be frozen,

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 allowable internal pressure [P] formula for a thick walled tube: [P] = [sigma] (K^2-1) / (K^0.5, K^2): K=D/dAccording to the latter company, you can count it back.

Q: What's the difference between the cylinder and the hydraulic?: The cylinder is compressed air as the power source, installation, use and maintenance are very simple and convenient, hydraulic cylinder is hydraulic oil as the power source of great output.

Q: What's the difference between an electric hydraulic and a pneumatic jack?: The two are the same: the executing agencies are hydraulic piston rod. The difference between the two is: electric hydraulic motor drives the oil pump, so that oil into the hydraulic cylinder, push the piston rod to work. Pneumatic hydraulic jack is two cylinder: the smaller cross-sectional area of the cylinder and the area of the cylinder when the cylinder gas of large capacity into small capacity, will produce several times, even ten times of pressure on the small cylinder, the output of small cylinder piston rod increases greatly, this method is called "liquid booster". Also called the cylinder pressure cylinder.Here is a very simple introduction, the actual structure is more complex, the principle will not be repeated, please refer to the relevant information.
