UAE hydraulic cylinder,pressure plate hydraulic cylinder manufacturer,pressure plate hydraulic cylinder

(UAE pressure plate hydraulic cylinder,produced by Hebei Hengyu company）

pressure plate hydraulic cylinder are widely used in UAE，because of smooth movement，no need for deceleration device，long service life.So our company has designed pressure plate hydraulic cylinder for customers from UAE.

Introduction to pressure plate hydraulic cylinder:

The difference between the plunger pressure plate hydraulic cylinder and the piston pressure plate hydraulic cylinder is that the piston in the pressure plate hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type pressure plate hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

What kind of process is used in the pressure plate hydraulic cylinder to make high-quality pressure plate hydraulic cylinder products: the body is the main component of the pressure plate hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The pressure plate hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the pressure plate hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the pressure plate hydraulic cylinder increases by 25%. If the service life of the pressure plate hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. pressure plate hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the pressure plate hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and pressure plate hydraulic cylinder are stuck or the pressure plate hydraulic cylinder is blocked. At this time, no matter how to manipulate, the pressure plate hydraulic cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the pressure plate hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

pressure plate hydraulic cylinder and hydraulic station selection: Select the type and structure of the pressure plate hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the pressure plate hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the pressure plate hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the pressure plate hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the pressure plate hydraulic cylinder, the diameter of the piston and the piston rod.

The main role of the pressure plate hydraulic cylinder: the pressure plate hydraulic cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the pressure plate hydraulic cylinder realizes reciprocating motion. The structure of the pressure plate hydraulic cylinder has three categories: piston pressure plate hydraulic cylinder, plunger pressure plate hydraulic cylinder, swing pressure plate hydraulic cylinder, piston pressure plate hydraulic cylinder and plunger pressure plate hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing pressure plate hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the pressure plate hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The pressure plate hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Answers to some questions about pressure plate hydraulic cylinder:

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.

When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.
