(Greece pusher hydraulic cylinder,produced by Hengyu Group）

pusher hydraulic cylinder are widely used in Greece，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed pusher hydraulic cylinder for customers from Greece.

Introduction to pusher hydraulic cylinder:

Protection of the pusher hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the pusher hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the pusher hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the pusher hydraulic cylinder should be cleaned up in time.

When the pusher hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The pusher hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the pusher hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil pusher hydraulic cylinder should not be in direct contact with water vapor for a long time. The pusher hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the pusher hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the pusher hydraulic cylinder Before working, the pusher hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the pusher hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

The main role of the pusher hydraulic cylinder: the pusher 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 pusher hydraulic cylinder realizes reciprocating motion. The structure of the pusher hydraulic cylinder has three categories: piston pusher hydraulic cylinder, plunger pusher hydraulic cylinder, swing pusher hydraulic cylinder, piston pusher hydraulic cylinder and plunger pusher hydraulic cylinder to achieve reciprocating linear motion, output speed and thrust, swing pusher hydraulic cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the pusher hydraulic cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The pusher hydraulic cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Because of the slightly complex structure of the buffer pusher hydraulic cylinder, sometimes there will be problems, such as when the pusher hydraulic cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Answers to some questions about pusher hydraulic cylinder:

How to set the stroke of the cylinder?
Self-design should be based on product demand and practical application. The stroke of standard cylinder depends on the parameters the customer requires. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the speed and force of the linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.

How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.
