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: The 80 hydraulic cylinder is equivalent to the pressure of the larger cylinder: when the hydraulic system pressure is 100kg/cm2 80mm oil output is 5 tons, the pressure when the system pressure is 5kg/cm2 then the cylinder bore 360mm can output 5 tons

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 surface of the hydraulic rod is chromium, and it often causes strain, scratch, electric shock and so on. The routine method is slow to repair and the effect is not satisfactory. Don't want to play with copper, also do not want to use cold, patch method, because of poor adhesion, never long broken. Is there a better way to fix it?: Compared with welding repair technology, the problems of local high temperature will not occur. Electroplating repair technology is the use of electrolysis principle, the bath metal ions reduced to metal atoms, and deposited on the metal surface, forming a high binding force and a certain thickness of the repair layer.

Q: How to use hydraulic system to control the feeding of machine tool table and the positioning and clamping device of workpiece: I. Basic Structure of machine tools:1 supporting parts for mounting and supporting other parts and workpieces, bearing their weight and cutting forces, such as bed and column;2, change mechanism, used to change the speed of the main movement;3. Feeding mechanism is used to change the feed; spindle box is used to install the spindle of machine tool;

Q: What is the basic working principle of the cushion device in the hydraulic cylinder?: For the high-pressure system, also need auxiliary measures to cushion cylinder movement impact, close at each end of the cylinder stroke position, set the stroke the switch is controlled by the stroke switch of the hydraulic cylinder flow;

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: machinery and components, such as cylinders, cylinders and so on, whether the pressure vessel ah? Does the relevant manufacturer need relevant qualifications? FiveThere are two entirely different answers to the question. Which one is right? Hope that professionals pointing. Thank you: In hydraulic and pneumatic equipment, only the gas tank and accumulator belong to the pressure vessel and require qualification. The remaining electromagnetic valves, cylinders and cylinders do not belong to the pressure vessel

Q: Structure principle of return nitrogen cylinder of hydraulic shearing machine: It is a well sealed plunger cylinder with nitrogen enclosed inside. Its function is spring, when pressed, it is compressed. Return the blade back when returning.Ball head lubrication should be done well, otherwise it will be bad.

Q: Hydraulic shock absorbers and hydraulic buffers are the same thing?: This is achieved by Iglidur, RN56 material, good friction coefficient, low wear characteristics and high toughness of the material. In addition, this design allows the pistons to be removed from the cylinder, which is of great benefit to folding bicycles.
