(Finland stern plate hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
stern plate hydraulic cylinder are widely used in Finland，because of long service life，smooth movement，high work efficiency.So our company has designed stern plate hydraulic cylinder for customers from Finland.
stern plate hydraulic cylinder and hydraulic station selection: Select the type and structure of the stern plate hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the stern plate hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the stern plate hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the stern plate hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the stern plate hydraulic cylinder, the diameter of the piston and the piston rod.
The meaning of the stern plate hydraulic cylinder model marked by the stern plate hydraulic cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the stern plate hydraulic cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the stern plate hydraulic cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
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.
When purchasing the stern plate hydraulic cylinder, try to clarify the following parameters of the stern plate hydraulic cylinder: A. stern plate hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or stern plate hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right stern plate hydraulic cylinder type can be found accurately and quickly.
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.
In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.
