Belarus vehicle hydraulic cylinder,vehicle hydraulic cylinder manufacturer
(Belarus vehicle hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
vehicle hydraulic cylinder are widely used in Belarus，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed vehicle hydraulic cylinder for customers from Belarus.
At the rated pressure, the thrust of the vehicle hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the vehicle hydraulic cylinder is related to the diameter of the vehicle hydraulic cylinder, but not to the stroke of the vehicle hydraulic cylinder. Moreover, the larger the vehicle hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the vehicle hydraulic cylinder.
The "O" ring can be used as an auxiliary seal inside the vehicle hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the vehicle hydraulic cylinder, and can be completely sealed.
The definition of the minimum stable speed refers to the minimum movement speed of the vehicle hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the vehicle hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.
What kind of process is used in the vehicle hydraulic cylinder to make high-quality vehicle hydraulic cylinder products: the body is the main component of the vehicle 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 vehicle 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 vehicle 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 vehicle hydraulic cylinder increases by 25%. If the service life of the vehicle 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. vehicle 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 vehicle 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 vehicle hydraulic cylinder are stuck or the vehicle hydraulic cylinder is blocked. At this time, no matter how to manipulate, the vehicle 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 vehicle hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.
What is a differential cylinder?
The differential cylinder is by connecting the return oil of the rod cavity through the pipeline, allowing them to flow into the rodless cavity, thereby speeding up the extension speed of the piston rod. In fact, the cylinder is still the cylinder, but the oil circuit is related to the connection. The oil connection mode in which both chambers of a single rod hydraulic cylinder are fed hydraulic oil is called differential connection.
