Angola hydraulic cylinder,lift cylinder manufacturer,lift cylinder
(Angola lift cylinder,produced by Hengyu Hydraulic Cylinder Factory）
lift cylinder are widely used in Angola，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed lift cylinder for customers from Angola.
The repair method of the lift cylinder: the repair of the lift cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.
When the lift cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the lift cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the lift cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the lift cylinder can meet the requirements by grinding. However, the life and reliability of this repair lift cylinder are not high.
lift cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the lift cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.
When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the lift cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
What is the difference between hollow and solid oil cylinders?
Hollow solid cylinder, according to conventional understanding, refers to whether the piston rod is solid or hollow. General ordinary hydraulic cylinder, the piston rod is solid structure. Hollow hydraulic cylinder refers to a hollow piston rod structure of the hydraulic cylinder, see the attached figure. Piston rod hollow function: 1, the piston rod hollow, the middle can be threaded rod. For example, the clamping cylinder with a sawing machine, the piston rod center threading rod, part of the stroke through manual, part of the stroke hydraulic automatic walk. 2, the hollow hole of the piston rod can be used to direct the oil circuit to achieve special oil circuit. 3, the cylinder is relatively large, the piston rod is relatively large, and the stroke is longer, in this case, the piston rod is hollow to reduce the movement friction and lateral force.
What are the functions of hydraulic cylinders?
Hydraulic cylinder is a hydraulic actuator, the specific role depends on the installation occasion and the type of hydraulic cylinder. Hydraulic cylinder is mainly used in machinery, and it is the most important component of construction machinery. It is important core component which mainly provide power for machinery.
