Uganda hydraulic cylinder,tailplate hydraulic cylinder manufacturer,tailplate hydraulic cylinder(Uganda tailplate hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
tailplate hydraulic cylinder are widely used in Uganda,because of long service life,smooth movement,high work efficiency.So our company has designed tailplate hydraulic cylinder for customers from Uganda.
What kind of process is used in the tailplate hydraulic cylinder to make high-quality tailplate hydraulic cylinder products: the body is the main component of the tailplate 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 tailplate 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 tailplate 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 tailplate hydraulic cylinder increases by 25%. If the service life of the tailplate 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. tailplate 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 tailplate 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 tailplate hydraulic cylinder are stuck or the tailplate hydraulic cylinder is blocked. At this time, no matter how to manipulate, the tailplate 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 tailplate hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
The "O" ring can be used as an auxiliary seal inside the tailplate 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 tailplate hydraulic cylinder, and can be completely sealed.
The main role of the tailplate hydraulic cylinder: the tailplate 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 tailplate hydraulic cylinder realizes reciprocating motion. The structure of the tailplate hydraulic cylinder has three categories: piston tailplate hydraulic cylinder, plunger tailplate hydraulic cylinder, swing tailplate hydraulic cylinder, piston tailplate hydraulic cylinder and plunger tailplate hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing tailplate hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the tailplate hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The tailplate hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
When the tailplate hydraulic cylinder is in use, ensure that the tailplate hydraulic cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.
Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.
Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
