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:What kind of material is the hydraulic cylinder of loader?
There are two kinds of damage to the cylinder liner: the abrasion of the cylinder mirror and the corrosion on the outer wall of the cylinder liner. First, the cylinder mirror wear in the following situations: normal wear, abrasive wear, melting wear and corrosion, wear and so on. 1, normal wear, piston ring and cylinder mirror friction caused by, also known as friction and wear. The maximum wear position of the cylinder mirror surface is the position of the piston near the first ring at the top dead point, which often forms an obvious step. Because of this position, the maximum pressure of the cylinder piston ring on the mirror, the upper end of the cylinder with high temperature, abrasion resistance of metals decreased, at the same time, the piston at TDC speed is zero, the oil film is not easy to form, so the lower part of the cylinder wear mirror also larger. Abrasive wear is caused by heavy dust or carbon deposits in the air. Dust is sucked from the upper part, and the carbon deposits are formed in the upper part, so the upper part of the cylinder mirror is relatively worn. When the engine oil is thrown from bottom to top, the hard particles are affected by gravity, so the lower part of the cylinder is more worn. Abrasive wear is characterized by parallel, rectilinear strains of pulling from the cylinder mirror along the direction of the piston.
Q:The cylinder is the same as the cylinder, crane
2. the thrust of the cylinder is greater than that of the cylinder. Not only the high oil pressure, but also the diameter of the cylinder to avoid too big design;The 3. cylinder piston moves much faster than the cylinder piston. The gas tank shall be supplied with a large amount of rated pressure in a short time, while the high pressure oil shall be supplied by the high pressure oil pump in the course of operation, with limited flow.
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 power of dynamic components of hydraulic cylinder can be relatively large power components, the use of hydraulic system, the 2-- from the medium air is inexhaustible, no cost and supply difficulties, the gas used directly into the atmosphere, convenient. The hydraulic oil in the air, 3-- small viscosity, resistance is less than 4-- but the compression rate of air hydraulic oil is far greater than the hydraulic oil so it work smoothly and in order to better response sent greater output Torque, it is necessary to use the volume. Compared to swing vane motor. Many gear rack swing hydraulic cylinder. The torque is generated and transmitted by a driving gear is provided with a rack piston shaft lateral position achieved. According to the design, roller bearings, hydraulic balance or prop up the shear counterproductive gear tooth and the piston. The principle of swinging cylinder reciprocating movement of the hydraulic cylinder is driven by gear rack, the gear shaft is converted into reverse swing rotation, while the reciprocating cylinder thrust into the output torque of the gear shaft. The gear shaft is proportional to the swing angle and the length of the rack, so the gear shaft swing the angle can be arbitrarily selected, and greater than 360 degrees.
Q:What is the bad effect of the engine oil pressure on the engine when the oil pressure is too high or too low?
The engine is suitable for both the power generating device and the whole machine including the power unit (such as a gasoline engine, an aircraft engine). 2, the engine displacement is the sum of the engine cylinder volume, generally expressed as L. While the cylinder working volume refers to the volume of gas piston from TDC to BDC swept, also known as single cylinder displacement, it depends on the bore and piston stroke. Engine displacement engine is a very important parameter, it can represent more than the number of engine and the cylinder bore size, the engine of many of the indicators are closely related with the displacement. Generally speaking, the larger the displacement, the greater the output power of the engine.
Q:Does the hydraulic cylinder change the inner ring of the cylinder?
And the seals need to use fluorine rubber, so as not to corrode. But as to the cylinder cylinder with practice is not whimsical, there is such a usage, the pneumatic system has a natural defect, speed instability, especially in low speed, hydraulic pressure is very stable,
Q:Can hydraulic oil be used instead of turbine oil?
No, VG32 turbine oil has the best effect, and several others will cause viscosity in use, which will affect the overall efficiency of pneumatic components
Q:Using hydraulic devices to control the cylinder,
At the same speed, under the same thrust conditions, the hydraulic system is much more expensive than the pneumatic system. You can use the hydraulic station to control the cylinder. You might as well buy an air compressor alone.If you have a hydraulic station or a large central hydraulic source, you must use the hydraulic system, you can reduce the work pressure, down to 0.8 MPa, and then send the hydraulic oil to the cylinder, you can also work.
Q:Can the cylinder be used as an internal combustion cylinder? 5
I don't want to say anything about it, but I'm sure you can tell that the cylinder doesn't make the cylinder burn
Q:Can you tell me if the cylinder can be changed into an oil cylinder (low pressure)?
Yes, as long as your oil pressure is below 8KG on the line, but it is difficult to get such oil pressure, the general pressure of the pump above 70KG, if filled into the cylinder, it will burst.
