(Malaysia large tonnage cylinder,produced by Hebei Hengyu company）

large tonnage cylinder are widely used in Malaysia，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed large tonnage cylinder for customers from Malaysia.

Introduction to large tonnage cylinder:

large tonnage cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the large tonnage cylinder is placed for a period of time, the large tonnage cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

The material, shape and compression of the large tonnage cylinder seal have a great impact on the service life and work efficiency of the large tonnage cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

If the large tonnage cylinder slips or crawls, please check whether there is astringency inside the large tonnage cylinder, because the internal parts of the large tonnage cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the large tonnage cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the large tonnage cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

The difference between the plunger large tonnage cylinder and the piston large tonnage cylinder is that the piston in the large tonnage cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type large tonnage cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Answers to some questions about large tonnage cylinder:

How does the 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 components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.
