Dominica trailer hydraulic cylinder,trailer hydraulic cylinder manufacturer
(Dominica trailer hydraulic cylinder,produced by Hengyu Group）
trailer hydraulic cylinder are widely used in Dominica，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed trailer hydraulic cylinder for customers from Dominica.
The trailer hydraulic cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
After the trailer hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
Under normal circumstances, the trailer 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 trailer hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the trailer hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the trailer 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 trailer hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
The trailer hydraulic cylinder should be vented: when the trailer hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the trailer hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the trailer hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the trailer hydraulic cylinder, the oil is best entered and discharged from the highest point of the trailer hydraulic cylinder. trailer hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.
Why is the hydraulic cylinder of the larger excavator arm upside down?
The weight of the excavating arm of a large excavator will be very heavy, and an oil cylinder has two cavities, one is a rod cavity, and the other is a rodless cavity. The lifting force of the excavator is the product of the ortho-projection area of the piston rod cavity by the oil pressure, so the strength of the rodless cavity is much greater than that of the rod cavity. And the parallel bars with the piston rod facing down are also conducive to assembly and future maintenance. So a large excavator has to keep the cylinder facing down.
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.
