(Greece heat press hydraulic cylinder,produced by Hebei Hengyu company）

heat press hydraulic cylinder are widely used in Greece，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed heat press hydraulic cylinder for customers from Greece.

Introduction to heat press hydraulic cylinder:

At the rated pressure, the thrust of the heat press hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the heat press hydraulic cylinder is related to the diameter of the heat press hydraulic cylinder, but not to the stroke of the heat press hydraulic cylinder. Moreover, the larger the heat press 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 heat press hydraulic cylinder.

The heat press hydraulic cylinder is mainly composed of body, piston, piston rod, heat press hydraulic cylinder head, heat press hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the heat press hydraulic cylinder into two chambers, and moves reciprocally in the heat press hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the heat press hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the heat press hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the heat press hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the heat press hydraulic cylinder bottom and the heat press hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the heat press hydraulic cylinder The working medium of the heat press hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; heat press hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the heat press hydraulic cylinder: The buffer structure of the heat press hydraulic cylinder is to prevent the piston from colliding with the heat press hydraulic cylinder head at the end of the stroke.

After chrome plating of the piston rod of the heat press hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

The scar on the sliding surface of the heat press hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the heat press hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

Answers to some questions about heat press hydraulic cylinder:

How to select the propulsion cylinder according to the shield attitude, cylinder stroke, shield tail clearance and other factors?
Generally, the shield machine will be equipped with the corresponding cylinder. Soil pressure balancing machine, mud water balancing machine have the corresponding cylinder, there will be no insufficient cylinder force. In the jacking process of the pipe jacking machine, there are certain requirements for the jacking force of the cylinder.

What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.
