Bangladesh trunnion cylinder

(Bangladesh trunnion cylinder,produced by Hebei Hengyu company)

trunnion cylinder are widely used in Bangladesh,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed trunnion cylinder for customers from Bangladesh.

Introduction to trunnion cylinder:

How the cavitation of the trunnion cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the trunnion cylinder, resulting in corrosive damage to the parts.

trunnion cylinder hydraulic oil selection: The recommended working oil viscosity of the trunnion cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

Improve the service life of the trunnion cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the trunnion cylinder (such as the trunnion cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the trunnion cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the trunnion cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single trunnion cylinder exhaust.

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

Answers to some questions about trunnion cylinder:

How does the clamping cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, The executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, The control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, The auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.
