Burma hydraulic cylinder,lift cylinder manufacturer,lift cylinder

(Burma lift cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to lift cylinder:

lift cylinder buffer valve inspection and maintenance: For the valve buffer lift cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

When the lift cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the lift cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

Factors that should be considered when selecting the oil seal in the lift cylinder: some specific factors should be taken into account when selecting the oil seal in the lift cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: lift cylinder diameter, piston rod diameter, piston rod and piston groove size, lift cylinder working pressure, lift cylinder movement speed, hydraulic system oil temperature and lift cylinder working environment.

Answers to some questions about lift cylinder:

What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.

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.
