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 pressure is too high, the hydraulic tappet internal rigidity is too large, it is easy to cause its door closed tight and so on, the pressure is too low, the hydraulic tappet internal rigidity is too small, will cause the valve clearance is too big. And aggravate wear. Note that this is only a one-sided phenomenon. In fact, when the oil pressure is unstable, the hydraulic tappet itself can compensate for the lack of pressure. I hope the above answer will help you.

Q: What kind of material is the hydraulic cylinder of loader?: 2, the cause of the wear and tear is mainly caused by insufficient lubrication. The piston and piston ring move at high speed in the cylinder mirror. Under lubrication. Between the working face can not form the oil film, both friction surface has extremely small part, the metal direct contact, because the friction formation partial high heat dissipation does not walk, but when accumulates to a certain extent, will cause two people to melt the adhesion. At this time, if the oil film can be timely recovery, cleaning and cooling, so that these tiny weld parts fall off without expansion; if the oil film recovery slow, weld expansion, resulting in abnormal melting wear occurred in a large area, which is usually called cylinder. Melting wear generally occurs on the upper part of the cylinder mirror, near the first ring at the top dead point, where localized metal melting is stuck and uneven uneven edges of groove marks and folds. Cylinderscoring phenomenon is easy to happen in production without running internal combustion engine immediately load working conditions. Because the internal combustion engine cylinder is not thicker, the oil film is not easy to form, and the cylinder mirror surface and the piston surface convex place often have tiny metal contact, thus causing melting wear and even killing phenomenon.

Q: What are the differences and characteristics between punching machine and hydraulic press?: First, understand the definition of the two:Stamping machine: punching machine, also known as punch, mainly used for sheet metal parts processing.Hydraulic press: hydraulic press is a kind of machine which uses liquid as working medium and uses liquid to transfer pressure to realize various process.There are still many differences between the two, as followsIn principle: the stamping machine drives the flywheel through the motor, and through the clutch, the transmission gear drives the crank connecting rod mechanism, causes the slide block to move up and down, and drives the drawing mold to form the steel plate.

Q: Which pressure is the cylinder or hydraulic cylinder?: I used 80 hydraulic cylinders, and now I want to change the cylinder. I don't know how many cylinders I need to buyChasing the answerThis is not clear, sorry

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: What is the cold drawn cylinder of a hydraulic cylinder? How about his quality? Master, help! Thank you: What do you do with it, if it is hydraulic cylinder, then we usually use cold drawn seamless tube here

Q: How to distinguish hydraulic cylinders and cylinders?: Hydraulic cylinders, without external bolts, have most of the cylinders;The inlet and outlet are screwed and the cylinder is straight in;

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: Why is the digital hydraulic cylinder not widely used?: 2, hydraulic system plus flow flow valve; 3, do synchronous cylinder.

Q: We have to design a manual plunger water hydraulic pump, but the wall thickness of the cylinder will not be designed and checked. I follow the sigma delta is not less than PD/2[design is out of 10mm thick, but the teacher said 5mm can withstand the pressure of 150MPa, the material with corrosion resistant stainless steel can. Some of my parameters are the maximum cylinder pressure 140MPa, cylinder size d=18mm (can also be smaller), length 60 ~ 80mm, how can I design wall thickness? thank you very much indeed: The maximum allowable internal pressure [P] formula for a thick walled tube: [P] = [sigma] (K^2-1) / (K^0.5, K^2): K=D/dAccording to the latter company, you can count it back.
