El Salvador hydraulic cylinder,lifting platform cylinder manufacturer,lifting platform cylinder(El Salvador lifting platform cylinder,produced by Hengyu Hydraulic Co., Ltd)
lifting platform cylinder are widely used in El Salvador,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed lifting platform cylinder for customers from El Salvador.
The lifting platform cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure lifting platform cylinder can use 20 steel pipe, and the high pressure lifting platform cylinder can use 45 steel pipe.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the lifting platform 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%.
The lifting platform cylinder should be used correctly and maintained regularly. The lifting platform cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the lifting platform cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
The viscosity of the working oil used in the lifting platform cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
What is a two-way hydraulic cylinder?
Bidirectional hydraulic cylinder definition: The bidirectional hydraulic cylinder uses the oil as the working medium, transmits the movement through the change of the sealing volume, and transmits the power through the pressure inside the oil. The two-way cylinder has at least two oil ports, which are used to connect the hydraulic tubing, and control the extension and retraction of the cylinder by pressing.
Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
