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 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:What are the uses of hydraulic equipment, cylinders and cylinders?
Hydraulic equipment, cylinders, cylinders are used in the principle of hydraulic transmission power, in particular, low aerodynamic pressure, hydraulic high. At the same time, the environment
Q:What type of cylinder do you have?
1. straight line type: the advantage lies in the simple structure, the cost is low, therefore the small displacement mostly uses the straight line, the inferiority lies in the vibration is bigger.2.V: the advantage is that the structure is compact, the stability is good, the disadvantage lies in the straight line type expensive, suitable for large displacement.3. flat (arrangement can be regarded as V type 180 degree angle): the advantage of ultra low center of gravity, high speed, good stability, the disadvantage is that there are only two car plants in this way: Porsche and Subaru.
Q:What can be used in hydraulic equipment factory
Hydraulic press application:Sheet metal stretching, blanking, bending, flanging, cold extrusion, metal forming, and transverse pressing, bending, turning, correcting and other stamping processesThe utility model is also suitable for pressing, molding, pressing and molding of powder products and abrasive articles, as well as pressing and forming of plastic products and insulating products.Pressing process of plastic material. Such as powder molding, plastic molding.Hydraulic machinery is the mechanical transmission of pressure through hydraulic oil. (understood) (I am a mechanical student)Providing stable heavy load force. Used in cranes, cranes, machine tools, and many other aspects.
Q:Hydraulic cylinder application
About expansionWorking principle of hydraulic cylinderHydraulic transmission principle - the oil as the working medium, through the change in the volume of sealing to transport movement, through the oil pressure to transfer the power.1, the power part - the mechanical energy of the prime mover is converted to the pressure energy of the oil (hydraulic energy). For example: hydraulic pump.2, the implementation part of the hydraulic pump input oil pressure can be converted to drive the mechanical energy of the work mechanism. For example: hydraulic cylinder, hydraulic motor.3 、 control part used to control and adjust the pressure, flow and direction of oil flow. For example: pressure control valve, flow control valve and direction control valve.4. The auxiliary part connects the three parts together to form a system, which functions as oil storage, filtration, measurement and sealing. Examples include piping and fittings, tanks, filters, accumulators, seals, and control instruments.A little pressure applied in any certain volume of liquid, can equal transmission in all directions. This means that when using a plurality of hydraulic cylinders, and each hydraulic cylinder according to the speed of each pull or push, and the moving load speed depends on the required pressure.In the same range of bearing capacity of the hydraulic cylinder, the hydraulic cylinder carrying the minimum load will move first, and the hydraulic cylinder carrying the maximum load will eventually moveIn order for the hydraulic cylinder to move synchronously, to achieve the load being lifted at the same speed at any point, it is essential to use a control valve or a synchronous jacking system element in the system
Q:How do I calculate the flow rate of the hydraulic cylinder?
Hydraulic cylinder flow = hydraulic cylinder piston cross section * speedFor example: the cylinder speed of D10cm requires 10cm per secondThe hydraulic cylinder piston cross-section =pi * D * D, 4=3.14 * 10 * 10 4=78.5 / cm2Flow per second =78.5 * 10=785 ml =0.785 litersThe flow rate is =0.785 * 60=47.1 liters per minute
Q:About the problem that hydraulic cylinders can take the place of cylinders
1, the hydraulic pressure station is larger;2. hydraulic oil is easy to pollute the surrounding environment;3, the speed and pressure characteristics are different and need to be redesigned and adjusted
Q:Can cylinder be used as cylinder, cylinder and hydraulic cylinder, Yantai hydraulic cylinder?
Cylinder instead of hydraulic cylinder, because the cylinder and hydraulic cylinder applicable to different systems, the form of seal, structure and so on are different.
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.
