S.Africa lifting column cylinder

(S.Africa lifting column cylinder,produced by Hengyu Hydraulic Cylinder Factory)

lifting column cylinder are widely used in S.Africa,because of clever hydraulic energy conversion,no transmission clearance,long service life.So our company has designed lifting column cylinder for customers from S.Africa.

Introduction to lifting column cylinder:

The lifting column cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

lifting column cylinders in series, parallel and series parallel. Series: In the lifting column cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the lifting column cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the lifting column cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the lifting column cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the lifting column cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

When installing the lifting column cylinder, the axial ends of the lifting column cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the lifting column cylinder, there is axial expansion. If the two ends of the lifting column cylinder are fixed, all parts of the lifting column cylinder will be deformed. When disassembling the lifting column cylinder, it is strictly forbidden to hammer the lifting column cylinder and the piston surface, such as the lifting column cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about lifting column cylinder:

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.

What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.
