(Algeria lift cargo elevator hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

lift cargo elevator hydraulic cylinder are widely used in Algeria，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed lift cargo elevator hydraulic cylinder for customers from Algeria.

Introduction to lift cargo elevator hydraulic cylinder:

If it is found that the lift cargo elevator hydraulic cylinder lubrication is poor or the lift cargo elevator hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the lift cargo elevator hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the lift cargo elevator hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the lift cargo elevator hydraulic cylinder center line. In this way, when the piston works in the lift cargo elevator hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the lift cargo elevator hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

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 lift cargo elevator hydraulic 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 producing oil lift cargo elevator hydraulic cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

The quality of the lift cargo elevator hydraulic cylinder can not be ignored in the purchase of the lift cargo elevator hydraulic cylinder. The lift cargo elevator hydraulic cylinder is the main component of the lift cargo elevator hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. lift cargo elevator hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of lift cargo elevator hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

Answers to some questions about lift cargo elevator hydraulic cylinder:

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.

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.
