Customers who have a certain grasp of hydraulic cylinders and other related products know that the gap between them is relatively sealed. What should we pay attention to in daily use? The following editor will introduce the use of hydraulic cylinders to you. Precautions and maintenance methods, I hope to help you.
1. Precautions for the use of hydraulic cylinders
Hydraulic cylinder is an implementation component in hydraulic control system, which is an energy conversion device that converts hydraulic function into mechanical kinetic energy. The oil motor maintains the continuous rotational fitness movement, while the hydraulic cylinder maintains the reciprocating movement. The structural forms of hydraulic cylinders include piston rod cylinders, plunger pump cylinders and swing cylinders. The piston cylinders and plunger pump cylinders maintain reciprocating uniform linear motion, output rate and thrust, and the swing cylinder maintains reciprocating swing, and the output angular velocity (speed ratio) and torque. In addition to being used alone, hydraulic cylinders can be used in two or more combinations or in combination with other organizations. for unique functions. The hydraulic cylinder is simple in structure and reliable in work, and has been widely used in the hydraulic transmission system of CNC lathes.
Hydraulic cylinder is a hydraulic machine implementing component that converts hydraulic function into mechanical kinetic energy and performs parallel line reciprocating motion (or swing fitness exercise). It is simple in construction and reliable in operation. When it is used to maintain the reciprocating motion, the deceleration device can be omitted, and there is no gap in the transmission system, and the fitness movement is stable, so it is used in the hydraulic transmission system of various mechanical equipment. The output force of the hydraulic cylinder is proportional to the reasonable total area of the piston rod and the pressure difference on both sides; the hydraulic cylinder is mostly composed of the cylinder liner and the cylinder head, the piston rod and the piston rod, the sealing device, the buffer device and the exhaust pipe device. The buffer device and the exhaust pipe device depend on the actual application site, and other devices are indispensable.
There is a dynamic seal between the cylinder head and the piston rod. Due to the poor production, processing and assembly lines of the engine block, cylinder head, piston rod and piston rod, or the bending and deformation of the piston rod, when the hydraulic cylinder is working, the centerline of the piston rod and the engine block is skewed, which makes the cylinder head sealing ring One-sided deformation results in oil seepage where the piston rod and cylinder head cooperate with each other.
2. Maintenance of hydraulic cylinders
1. When using the cylinder, the gear oil should be replaced on time to clean the system software filter device to ensure cleaning and increase the service life.
2. Control the temperature of the hydraulic cylinder. If the water temperature is too high, the service life of the hydraulic seal will be reduced. Long-term water temperature can cause the seal to deform and become completely ineffective.
3. Every time a hydraulic cylinder is used, be sure to perform a complete telescopic inspection of the four-stroke for 5 times and then load it. According to this type of method, the gas in the system software can be depleted, the various system software can be heated, and the existence of gas or water in the system software can be reasonably prevented, causing the gas explosion (or scorching), which can damage the hydraulic seal parts and cause common faults such as leakage inside the cylinder.
4. Maintain the outer surface of the piston rod to avoid seal damage caused by impact and scratches, and often clean the cylinder seal and the anti-fouling seal on the exposed piston rod to avoid light clay on the surface. piston rod. Objects get inside the cylinder to damage the piston rod, cylinder or hydraulic seals.
5. Always lubricate the connector to avoid corrosion or abnormal damage in the absence of oil.
6. Try to check the connection between the external thread of the hydraulic cylinder and the anchor bolt, and if it is found that it falls off, it is immediately tightened.
In short, we should always pay attention to the problems found in the use of hydraulic cylinders, and eliminate them in time. It is to check and correct the hydraulic cylinders regularly to ensure normal use. The above are the precautions for the use of hydraulic cylinders and the relevant introduction of maintenance methods. I believe everyone After reading it, I have a certain understanding, I hope it can help you.
