Q:Hydraulic cylinder application
Hello, hydraulic cylinder products are widely used in metallurgy, lifting, mining, transportation, ships, forging, machine tools, coal, oil, chemical, scientific research, military, and other industries. It is a hydraulic actuator that converts hydraulic energy into linear motion and mechanical work.The cylinder converts the pressure energy of the compressed air into mechanical energy, and the drive mechanism acts as a linear reciprocating motion, swinging and rotating motion. Mainly used in printing (tension control), semiconductor (spot welder, chip grinding), automatic control, robot and so on.
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:Pneumatic cylinder stem can replace pneumatic hydraulic jacking rod. Who is big?
First of all, to understand your question is..:Can the top rod of the pneumatic cylinder piston rod instead of the piston rod of the hydraulic cylinder? That lever has a lot of thrust?" How is that right?Answer as followsThe top rod of a pneumatic cylinder piston rod can not replace the top rod of a hydraulic cylinder piston rod.
Q:What is the pivot shaft in the cylinder?
The hinge shaft is a kind of hydraulic installation method. After installation, the hydraulic cylinder can swing. This cylinder is a hydraulic cylinder with a hinged shaft.
Q:The difference between cylinder and hydraulic cylinder
At the same weight, the cylinder is heavier than the cylinder,In the form of output, the output load of the cylinder is relatively light, and the load of the hydraulic cylinder is heavy load,
Q:This is the model of a hydraulic buffer tank used on an oil rig. Who can explain the meaning of this model to me, especially the meaning of 550*905, and also provide the best drawings
HSG--- double acting single piston hydraulic cylinder, piston type K--- card key, 01--- for the Y type sealing ring, 160/110E--- bore diameter is 110, 160, a pressure of 16MPa, 5221---5 said the cylinder head or cylinder middle flange connection, 2 piston rod end thread, 2 (second 2) the cylinder head end buffer 1 oil port internal thread; 550 stroke, 905 for the minimum installation distance.
Q:The 80 hydraulic cylinder is equivalent to the pressure of the larger cylinder
It depends on how much you supply the hydraulic system hydraulic cylinder pressure, there is a gas path set pressure output size of the cylinder,
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: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 is pneumatic oil? Is it the same as hydraulic oil?
Pneumatic and hydraulic oils are not oils. Pneumatic lubricants require high oxidation resistance and lubricity, while hydraulic oils require good abrasion resistance, oxidation resistance, lubricity and foam resistance as well as anti emulsification effects. Pneumatic lubricants are generally thinner than hydraulic oils.
