Q: I would like to ask if the speed of the hydraulic cylinder is related to the load on the piston rod?Proportional flow valve how to type, I currently only know the maximum pressure 2.5Mpa, according to Q=VA count as 0.4L/min, 1L/min can be chosen according to the ratio of flow valve? Is there another way to choose?: How to choose the proportion of flow valve, mainly based on the flow to control the size and accuracy, pressure levels, as well as some of the owners of the special requirements of the brand.As you say 0.4L/min this small flow proportional flow valve, can choose the brand is not much, Rexroth 2FRE6 series should be able to meet your requirements. As you said, the choice of 1L/min proportional flow valve is very appropriate, in the recommended electric signal 25%~75%.

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: How much is the 1000 ton hydraulic cylinder: The rated working pressure of general press is 25MpaUsually made of 700mm large diameter (the actual calculated is about 715)

Q: What can be used in hydraulic equipment factory: Hydraulic press application:Sheet metal stretching, blanking, bending, flanging, cold extrusion, metal forming, and transverse pressing, bending, turning, correcting and other stamping processesThe utility model is also suitable for pressing, molding, pressing and molding of powder products and abrasive articles, as well as pressing and forming of plastic products and insulating products.Pressing process of plastic material. Such as powder molding, plastic molding.Hydraulic machinery is the mechanical transmission of pressure through hydraulic oil. (understood) (I am a mechanical student)Providing stable heavy load force. Used in cranes, cranes, machine tools, and many other aspects.

Q: What is the four link mechanism of hydraulic support?: 2. The connecting rod must have sufficient fatigue strength and structural rigidity. The lack of fatigue strength often results in fracture of the connecting rod or connecting rod bolt, thus causing a serious accident of the whole machine. If the stiffness is not enough, it will cause the bending deformation of the rod and the deformation of the big part of the connecting rod, resulting in partial wear of the piston, cylinder, bearing and crank pin.

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: What is the essential difference between hydraulic oil and lubricating oil?: The lubricating oil includes hydraulic oil is a kind of lubricating oil is a general hydraulic oil lubricating oil for a strong oil

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: Does the hydraulic cylinder change the inner ring of the cylinder?: if you do not want to buy a set of hydraulic system, and the power to the cylinder is not large, you can use compressed air to promote the hydraulic oil, hydraulic oil cylinder to drive, such as power and compressed air, but very smooth.

Q: Difference between cylinders of hydraulic cylinders: The working principle is very simple by using the Pascal principle (F1/A1=F2/A2), the advantages do not need lubricating oil, because his work is medium, and he can realize remote control, can realize stepless speed, no noise etc......
