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:Difference between cylinders of hydraulic cylinders

The two principle is the same, but the working medium is not the same, one is hydraulic oil, and the other is gasThe hydraulic cylinder is the use of pump oil into the cylinder, on the way to a series of valves such as benefits flow valve valve valve sequence valve check valve control, the main work is the process of the machine is simple and not, some do not need to.

Q:What are the differences and characteristics between punching machine and hydraulic press?

The hydraulic press is that the oil pump transfers the hydraulic oil to the integrated cartridge block, and the hydraulic oil is distributed to the upper cavity or the lower chamber of the oil cylinder through each one-way valve and an overflow valve, and the oil cylinder is moved under the action of the high pressure oil.Use: the machine is suitable for hydraulic load center parts forming, bending, flanging and other processes, with a blanking buffer device, can also be used for punching, blanking and processing, is the product of choice for the shipbuilding industry, pressure vessel industry and chemical industry. Stamping machine is mainly used for sheet metal parts processing.classification

Q:In hydraulic knowledge, the working principle of pneumatic triple parts

Pneumatic tool with: 1, can be used in explosive, corrosive, high temperature and damp environment; 2, overload operation without causing motor burned; 3, simple structure, durable, relatively easy to maintain; 4, large output torque, light weight and high efficiency; 5. Stepless speed regulation, and can produce a rotating, reciprocating movement and impact; and other advantages, and is widely used in the modern machinery manufacturing, shipbuilding, automobile manufacturing and other fields, especially in automobile manufacturing, grinding, polishing, spraying, assembly and other conditions are widely used in the production process, is a modern the automobile industry is an indispensable important batch of large-scale production equipment, but because in the automobile manufacturing industry, nearly 90% of the vehicle assembly connection through a screw thread, so pneumatic tightening tools in the whole It is widely used in vehicle assembly. Broadly speaking, pneumatic tool is the use of compressed air motor to output kinetic energy work on a tool with the general pneumatic tool mainly comprises a power output part, operation part, transformed into the exhaust path, open and stop operation control part, the main part of a tool, of course, pneumatic operation tools must also have the energy supply part, air filter and pressure regulating part and tool accessories etc..

Q:UG4.0 parts library, what cylinders, motors, cylinders are standard parts for the equipment?

I give you an online version of it, can go to the site to download the linkable.partcommunity, I have been using CAD material, can download, support UG format and some other CAD format, no requirement for computer system.

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: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 relays, solenoid valves, push buttons, switches, switches, and so on. It depends on what you need

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:always have hydraulic oil leakage, please expert advice, with what seal can avoid, the best zero leakage.

200 / min work frequency, high viscosity, slow flow, affect operation sensitivity.It is precisely the year that is too low to cause disclosure. Try to increase viscosity properly.This is a contradiction.

Q:What is pneumatic oil? Is it the same as hydraulic oil?

The main function of pneumatic lubricating oil is to lubricate, and the main function of hydraulic oil is to transmit pressure, and the two can not be mixed
