flange type cylinder are widely used in Spain，because of long service life，smooth movement，high work efficiency.So our company has designed flange type cylinder for customers from Spain.

Introduction to flange type cylinder:

The internal leakage of the flange type cylinder is an important indicator to measure the quality of the flange type cylinder: the internal leakage of the flange type cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the flange type cylinder, so that the flange type cylinder can not accurately and stably stop in a certain position of the flange type cylinder, so it is one of the main indicators of the flange type cylinder.

When the flange type cylinder is customized, if there are high requirements for the quality of the flange type cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the flange type cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the flange type cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

If air enters the hydraulic system, the flange type cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

When purchasing the flange type cylinder, try to clarify the following parameters of the flange type cylinder: A. flange type cylinder diameter, rod diameter, stroke; B. Working pressure or flange type cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right flange type cylinder type can be found accurately and quickly.

Answers to some questions about flange type cylinder:

What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.

Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).
