Q:Pneumatic cylinder stem can replace pneumatic hydraulic jacking rod. Who is big?
The former is different from the latter in structure, material and service performance. In the same size of the cylinder and piston rod diameter under the condition of using hydraulic working oil pressure cylinder is generally above 50~110kg/cm2; the use of pneumatic pressure in the cylinder is generally only 5~7kg/cm2 (permissible pressure of not more than 10kg/cm2).
Q:What does hydraulic cylinder type "HSG 80/60-1100" mean?
For more information, you can see the mechanical design manual, Cheng Daxian editor, volume fifth, twenty-first pages of -305 hydraulic transmission.
Q:What is a constant velocity cylinder? What's the difference between a hydraulic cylinder and a hydraulic cylinder?
The cylinder piston rod extends out should be constant and consistent back speed cylinder called isokinetic cylinder. The difference between it and ordinary hydraulic cylinder hydraulic cylinder is common only a head with a piston rod extends out of the general slow recovery fast, because the relationship between the effective area of the piston cavity.
Q:Hydraulic shock absorbers and hydraulic buffers are the same thing?
A shock absorber is used between the swing arm rear suspension and the frame to cushion the impact of the bicycle. Traditionally, this is a cylinder in which the piston moves in a reciprocating motion in a straight line. The problem here is that, for such a design, if you want to be lightweight and robust, the cost will be very expensive to adopt the previous solution.
Q:The cylinder is the same as the cylinder, crane
The basic principle is the same, because of the different working medium, the difference is that:1. the working pressure of the cylinder is much higher than that of the cylinder. High pressure gases are much more dangerous than high pressure liquids;
Q:How to distinguish hydraulic cylinders and cylinders?
Can be from the weight, oil port connector, respectively. The cylinder is usually made of Q235 or cast iron, the quality is heavier; the cylinder is usually made of alloy steel, and the quality is lighter. The joint of the cylinder is usually flanged connection or pipe thread connection; the joint of the cylinder is usually expanded or inserted or directly sheathed by the hose.
Q:Computer automatic packing machine, cylinder voice suddenly become larger, how to solve?
2 the hydraulic pump leaking into the hydraulic cylinder causes the hydraulic oil in the cylinder not sufficiently large to be injected, resulting in no action of the hydraulic cylinder;
Q:Does the hydraulic cylinder change the inner ring of the cylinder?
The cylinder can only be used under 1MPA pressure, and the use of the cylinder can only be a little bit pressure. It may not meet the strength requirements.
Q:Does the hydraulic cylinder speed change with the load? Ten
How to choose the proportion of flow valve, mainly based on the flow to control the size and accuracy, pressure levels, as well as some of the owners of the special requirements of the brand.As you say 0.4L/min this small flow proportional flow valve, can choose the brand is not much, Rexroth 2FRE6 series should be able to meet your requirements. As you said, the choice of 1L/min proportional flow valve is very appropriate, in the recommended electric signal 25%~75%.
Q:Hydraulic cylinder application
Hello, hydraulic cylinder products are widely used in metallurgy, lifting, mining, transportation, ships, forging, machine tools, coal, oil, chemical, scientific research, military, and other industries. It is a hydraulic actuator that converts hydraulic energy into linear motion and mechanical work.The cylinder converts the pressure energy of the compressed air into mechanical energy, and the drive mechanism acts as a linear reciprocating motion, swinging and rotating motion. Mainly used in printing (tension control), semiconductor (spot welder, chip grinding), automatic control, robot and so on.
