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: 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: 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: Are hydraulic cylinders, oil cylinders, hydraulic cylinders all the same? What's the difference?: It's all about one thingI am the repair cylinderThe cylinder is all hydraulic, so it is called a hydraulic cylinder and a hydraulic cylinder, both of which mean one

Q: used as the form of a connecting rod or piston in an automobile crankshaft. What is the minimum allowable value for such a hydraulic cylinder?. This way, the supply of oil cylinder in the rear, I ask the output cylinder allowed the maximum number of transfer, such as cooling good, the highest output can be transferred. How many manufacturers are there in the market?.: Yes, but this requirement is very high, and the input power is also greater. I don't know what you do

Q: How to distinguish hydraulic cylinders and cylinders?: The material of the cylinder is that the alloy is very light, and the hydraulic cylinder is very heavy;

Q: After running in, the upper cylinder head, the hydraulic jacking rod and the rocker arm are also arranged in the original position, and the cylinder head is not provided with a valve body without gaps: I. valve clearance: when the valve is completely closed, the gap between the end of the valve stem and the component of the valve train is called the valve clearance. Two, the valve clearance is necessary: when the engine works, the valve will be due to temperature expansion, if the valve and its transmission parts, in the cold when no gap or clearance is too small, in the hot state, and the transmission of the thermal expansion valve will cause the valve is not tightly closed, causing the engine leakage in the power stroke in compression and the power down, don't even start easily when serious. In order to eliminate this phenomenon, the valve clearance is usually used in the cold assembly of the engine to compensate for the expansion after the valve is heated. Some engines use hydraulic tappet, the length of tappet can change automatically, and the thermal expansion of the valve is compensated at any time, so there is no need to reserve the valve clearance. Three, the valve clearance is too large and too small damage, the size of the valve clearance by the engine manufacturer, according to the test to determine. Generally in cold state, the clearance of intake valve is 0.25mm~0.35mm, and the clearance of exhaust valve is 0.30mm~0.35mm. 1, too small: if the valve clearance is too small, the engine in hot state may be due to valve closed lax and leak, leading to power down, or even valve burned.

Q: What are the components of the cylinder and the hydraulic cylinder?: Hello, are you asking about the cylinders and cylinders? Cylinder barrel, upper and lower end cover, pull rod, sealing ring and so on. I am a professional, do this, what problems can continue to ask me?

Q: About the problem that hydraulic cylinders can take the place of cylinders: The output power of the cylinder is limited, within a small range, can be more than a certain pressure, it must be hydraulic, and good stability

Q: Application of pneumatic hydraulic pump: Static pressure and explosion tests for hoses, valves, pressure vessels, etc.Automobile brake system and nozzle testPerformance test and pressure calibration of instrument and meter (such as pressure gauge)Water pressure test of building material testing machineHigh pressure cleaning and water cutting equipment water jetDeliver a chemical medium to a pipe or reactorTransport fluids in hazardous areasRefrigerant cansLubrication of lubrication system of mechanical equipmentHydraulic clamping, forming, drilling, cutting, stamping and other hydraulic equipment power sourceOverload protection of large pressClamping power source for valve testSleeve and cylinder liner press in and press out powerReinforcement crimping powerHydraulic tools power 1, engineering technology industry;1) for hydraulic clamps, valves, cylinders, etc.;2) used for routine pressure test of mobile hydraulic pump station;3) hydraulic pumping station is used for hydraulic overload device;4) bolt tension and torque wrench;5) for the gear and couplings, such as interference fit disassembly and assembly;6) hydraulic accumulator nitrogen charging.
