(Bahrain stern plate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

stern plate hydraulic cylinder are widely used in Bahrain，because of no need for deceleration device，long service life，smooth movement.So our company has designed stern plate hydraulic cylinder for customers from Bahrain.

Introduction to stern plate hydraulic cylinder:

stern plate hydraulic cylinder body inspection: The inner surface of the stern plate hydraulic cylinder and the piston seal are the main factors causing the leakage in the stern plate hydraulic cylinder, if the stern plate hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the stern plate hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Under normal circumstances, the stern plate hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the stern plate hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the stern plate hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the stern plate hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the stern plate hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

The piston seal of the stern plate hydraulic cylinder is the main element to prevent leakage in the stern plate hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

In the process of using the stern plate hydraulic cylinder, sometimes such a problem will occur, the stern plate hydraulic cylinder can not act immediately after the instruction of the stern plate hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil stern plate hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Answers to some questions about stern plate hydraulic cylinder:

How does the cylinder of the shearing machine work?
Plate shear is a machine that cuts a sheet with a reciprocating straight motion from one blade to another. Through the moving upper blade and the fixed lower blade, the shear force is applied to the metal sheet of various thicknesses with a reasonable blade gap, so that the sheet is broken and separated according to the required size. Shearing machine belongs to one of the forging machinery, the main role is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment. Working principle: The hydraulic system is used to drive the hydraulic cylinder to output a strong shear force to complete the shearing work.

PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.
