Q: For example, I press a workpiece with a hydraulic press, and the pressure gauge shows 0.3MPa. Then I change the cylinder pressure. When I type, I choose the 0.3MPa cylinder instead of the inner diameter of the cylinder.: No, you want the workpiece to be the force, and the pressure gauge shows the pressure. F=PXS. If ventilation occurs, the cylinder bore and air pressure need to be recalculated.

Q: What are the differences and characteristics between punching machine and hydraulic press?: Punching machine classification:Press the driving force of the slider, mechanical punching machine, hydraulic pressAccording to the movement of the slider, single movement, re movement, hyperactivityAccording to the structure of the crankshaft drive slider type punch crankless press, toggle press, friction type punching machine, screw press, pinion press, connecting rod type punch cam punchClassification of hydraulic pressHydraulic press can be divided into hot forging hydraulic press, four column hydraulic press, single arm hydraulic press, Longmen hydraulic press, double column hydraulic press

Q: What do three hydraulic cylinders need? Is it okay to use PLC? Specific point, I do not understand electricity 10Two cylinder and clamp the workpiece, a feeding cylinder, a hydraulic cylinder to the specified length after the 1 clamping, then another hydraulic cylinder 2 to the workpiece chamfering quickly return hydraulic cylinder 3, cutting, cutting material after rapid return, the hydraulic cylinder 1 and a clamping cylinder and cylinder return return evacuation then, the next clip material feeding cycle. ----...: Yes, you need a relay, solenoid valve, depending on how you apply, and what action you need.

Q: Does the car have no cylinder pressure? Is it related to the hydraulic bottom support?: There is no cylinder pressure for more reasons, the general cylinder internal cylinder sleeve, piston, piston ring and valve wear and timing, hydraulic systems, pressure relief, etc., need to be checked in order to confirm the cause of the failure

Q: Multi axis drilling hydraulic system design of a horizontal cylinder in the machining production line (conditions: positioning, clamping hydraulic control, machine tool positioning clamping action sequence: - - - - - feeding slide fast forward rewind - stop - release - pull pin fixture, machine work axial cutting force 25000N, acceleration deceleration inertia force 500N 1500N, static friction resistance, friction resistance 850N, fast forward, rewind speed is 100mm/S and the feeding speed of 833mm/min, fast travel 0.1M of 0.04m. Worktable adopts flat guide rail)Tasks and requirements:Determine component specifications and complete hydraulic system loop diagram 1;2. Design the assembly drawing of the hydraulic cylinder 1;3, according to the prescribed format to complete the design, calculation manual 1.: The design has to be replaced by moneyChange the design with a reward, dream!In addition, the use of hydraulic pressure to feed the power, can not guarantee a stable speed bar, careful processing tool was cracked

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: How to remove the hydraulic cylinder oil seal?: 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: The main difference between hydraulic circuit and pneumatic circuit: I. pneumatic basic circuit is the basic component of pneumatic circuit, and complex pneumatic operation system is composed of one or more basic circuits. Compared with hydraulic, pneumatic circuit has its own characteristics:1, an air compressor can simultaneously supply gas to multiple circuits, while hydraulic pumps generally provide only one loop.2. The compressed air will be discharged into the atmosphere directly after the end of the cycle. No hydraulic drive will be necessary to recover the oil into the tank.3, air senior lubrication performance is poor, need additional oil supply device.Two, through the introduction of the previous articles, we generally understand the hydraulic circuit and the use of pneumatic circuit, as well as related presentations, and then we will explore how the cylinder should be chosen.Standard cylinder selection process is generally based on the needs of the job to determine the type of cylinder, installation forms, working pressure, cylinder and stroke, cylinder standard series and product samples for selection, gymnastics as;1, the cylinder output size of the load by 1.15~2 times to select, and accordingly determine the cylinder bore.2, according to the implementation of the agency's travel requirements to determine the cylinder piston stroke length, usually need to leave the margin of 5-20mm.3, according to the speed of the piston movement, select the appropriate inlet diameter, the greater the value, the faster the speed. In order to make the speed steady, a cylinder with a buffer device can be used.

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: Hydraulic shock absorbers and hydraulic buffers are the same thing?: Through the application of a new design, this feature is the use of Iglidur RN56 as the core component, can meet the technical requirements and significantly reduce costs. In this solution, the piston and the sliding bearing at the bottom of the damper are combined in an injection molding assembly.
