1.ROB circular cylinder, the structure is simple. Manufacture and installation are

convenient.

2.Working medium as the standard of hydraulic oil. Can use a variety of installation

(front flange, flange, earrings, after the middle pendulum shaft, etc.)

3.Applicable scope pressure is 0.3 mpa - 14 mpa, suitable temperature range for

- 10-70 degrees.

4.For the selection of hydraulic oil cylinder, we generally in the process of hydraulic

cylinder will be in accordance with the inner diameter, stroke, working pressure,

installation type to choose hydraulic oil cylinder, in fact, in addition to these outside,

still have the following points are worthy of our to notice after the first hydraulic

cylinder load moving speed reaches more than a certain standard, must need

have a buffer device of the hydraulic cylinder. Or outside on the hydraulic cylinder

to achieve higher speed must be equipped with reduction valve. Followed by the

choice of hydraulic oil and oil seal. Different hydraulic oil droplets with different

material of oil seal, to ensure the service life of hydraulic cylinder.

5.Because the hydraulic oil cylinder to bear a lot of pressure, the heavier load, the

pressure will be greater, therefore, do a good job in the maintenance of hydraulic

oil cylinder is the maintenance of the hydraulic system is the most important one

annulus.

6.Hydraulic oil cylinder is equivalent to the hydraulic system of the heart, heart

problem is very difficult to repair, so the maintenance of the hydraulic oil cylinder

is careful and detailed.

7.First of all, it will rust. Because the hydraulic oil cylinder piston parts in a state

of work is to stretch out oil cylinder, will naturally be oxide, the erosion of acid

gases, this needs us to coating the right amount of grease to protect it, lest as

load-bearing parts in work by the piston erosion may be broken.

8.Next, want to out of the oil change. Because of long time use, hard to avoid

can have foreign body into the hydraulic oil cylinder, so in use will increase friction

phenomenon, in addition, the service life of hydraulic oil is also a certain, not an

oil change for a long time can damage or erosion of the hydraulic oil cylinder inside.

9.Is better than cure, so in the work of hydraulic oil cylinder to control the speed

properly, not more than 2 m/s, it can prolong the service life of hydraulic oil cylinder,

the other in order to protect the institutions and be on the safe side, the internal

installation buffer device is very effective for the protection of the hydraulic oil cylinder.
