Q: What is the difference between the cylinder seal and the cylinder seal?: The medium of bees is different. One is gas sealed, and the other is liquid sealed.

Q: The surface of the hydraulic rod is chromium, and it often causes strain, scratch, electric shock and so on. The routine method is slow to repair and the effect is not satisfactory. Don't want to play with copper, also do not want to use cold, patch method, because of poor adhesion, never long broken. Is there a better way to fix it?: Brush plating method to repair hydraulic rod, cylinder pull, the best effect. Because the 1. can be repaired on the spot, the trouble of loading and transporting is avoided. 2., coating adhesion is good, no obvious boundaries, repair surface hardness, good wear resistance. 3. low temperature operation will not change the properties of the substrate. Electroplating repair technology is a kind of traditional repair technology to restore the size of parts at low temperature.

Q: Hydraulic principle: A typical hydraulic system comprises a hydraulic pump, hydraulic oil tank, directional control valve, flow control valve, the working cylinder, plunger valve and pressure relief valve. Three kinds of typical hydraulic pump hydraulic system used in gear pump, vane pump and axial reciprocating pump. Pump is the power component liquid system is the heart of the hydraulic pump control element. (including the flow valve, relief valve, directional valve and proportional valve etc.) for controlling and regulating the fluid pressure. The flow and direction, to meet the performance requirements of equipments, and the realization of various work cycle, the implementation of components to the pressure of the liquid can be converted to mechanical energy, so as to drive the movement of the mechanism.

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 type of cylinder do you have?: 1) from the cylinder piston to withstand the pressure of gas is one-way or two-way classification (1) single acting cylinder: the piston of the cylinder can only be one-way pressure driven, reverse need to use external force. (2) double acting cylinder: the piston of the cylinder is driven by the air pressure in the two directions of both positive and negative directions. 2) classify the installation form of cylinder (1) fixed cylinder: cylinder block fixed. (2) axle pin type cylinder: the cylinder block can swing around the fixed axis pin at a certain angle. (3) rotary cylinder: the cylinder block is usually fixed on the main shaft of the machine tool, and can rotate with the main shaft of the machine. This kind of cylinder is usually used in the pneumatic chuck of the machine tool.

Q: What's the difference between an electric hydraulic and a pneumatic jack?: The two are the same: the executing agencies are hydraulic piston rod. The difference between the two is: electric hydraulic motor drives the oil pump, so that oil into the hydraulic cylinder, push the piston rod to work. Pneumatic hydraulic jack is two cylinder: the smaller cross-sectional area of the cylinder and the area of the cylinder when the cylinder gas of large capacity into small capacity, will produce several times, even ten times of pressure on the small cylinder, the output of small cylinder piston rod increases greatly, this method is called "liquid booster". Also called the cylinder pressure cylinder.

Q: Computer automatic packing machine, cylinder voice suddenly become larger, how to solve?: 3 there is no hydraulic oil in the hydraulic cylinder;4, there is no residual air in the hydraulic cylinder, which makes the hydraulic cylinder unstable and crawlingAlso is the likely cause of scuffing, don't move, check it apart

Q: Why do not the industrial furnace door use the hydraulic cylinder and the cylinder?: Hydraulic cylinder seal ring for industrial furnace door is easy to leak oil

Q: Hydraulic shock absorbers and hydraulic buffers are the same thing?: A shock absorber is used between the swing arm rear suspension and the frame to cushion the impact of the bicycle. Traditionally, this is a cylinder in which the piston moves in a reciprocating motion in a straight line. The problem here is that, for such a design, if you want to be lightweight and robust, the cost will be very expensive to adopt the previous solution.

Q: Hello, which units use hydraulic pneumatic cylinders and more cylinders?. Thank you: The meter on the unit of the cylinder is big, but there is more.And the hydraulic cylinder bore is greater.
