How to select festo cylinder
During the use of the FESTO cylinder block, deformation is often caused, thereby destroying the geometry of the part, and the Festo cylinder increases the relative positional deviation of the mating surface. When the deformation exceeds the allowable limit, the Festo cylinder will cause water leakage, air leakage, and damage to the air cushion. The warping of the top plane of the cylinder block is mostly caused by the uneven torque of the cylinder head bolt and the convexity of the screw hole caused by the bolt pulling force. When the Festo cylinder is installed, it should be tightened according to the specified torque, and the bolt cannot be tightened too tightly. After the Festo cylinder is disassembled, the cylinder block should be cleaned with a soft brush and solvent.
The upper and lower parts of the FESTO cylinder are connected by fasteners. The most common ones are bolts and nuts, which are tightly coupled to the upper and lower cylinders along the flanges of the outer and outer diameters of the upper and lower cylinders. In order to ensure the tightness of the flange joint surface, the FESTO cylinder split surface must be smooth and flat during the manufacturing process. The connection of the flange bolts is generally in the form of a heat tightness, that is, a certain pre-tightening force is applied to the bolts when the bolts are installed, and the tightness of the flanges can be ensured after a period of stress relaxation. In addition, the inlet portion of the mal micro-cylinder is arranged as dispersed as possible to avoid excessive local thermal stress and cause cylinder deformation.
1. For example, when the sensor switch is connected to the input end of the TPC8-8TD type timing program controller, it can be used as position-related motion control such as stop, in-position start, in-position alarm, and in-position alarm.
2. The magnetic switch or other switch sensor can be installed on the FESTO cylinder. Its function is to sense the working state of the qgbz cylinder, so that the control circuit can receive the signal of the induction switch to make the next action.
3. The control function of the qga cylinder is realized by the sensor switch and the controller. The specific function can set the required control function through the function setting table. This combination can realize the functions of various control devices.
For the precise selection of FESTO cylinders, I think many people are not very understanding, so what is the precise selection method of FESTO cylinders? Let's take a look at it together:
Step 1: Credentials use the situation to select FESTO cylinder
FESTO cylinders have three essentials: double action, single rotary spring press and single rotary spring extrusion.
Step 2: Select other parameters:
1. The selected magnetic sensor switch is used for position detection. It requires a built-in magnetic ring for the rodless cylinder.
2, selected FESTO cylinder accessories, qgbII cylinder
3. Select the FESTO cylinder bore diameter and the relevant load, use the atmospheric pressure and the direction of action.
4. Selected FESTO cylinder metallurgical cylinder series
5, selected FESTO cylinder installation type difference series has different installation essentials, emergency basic type, foot type, flange type, U type hook, shaft type
6, selected buffer unbuffered, rubber buffer, air buffer, hydraulic shock absorber
7, selected FESTO cylinder stroke workpiece movement repression
It is required to have high braking precision. The FESTO cylinder should be selected for locking; the piston rod is not allowed to rotate, and the FESTO cylinder with the rod not rotating result can be selected; the heat-resistant cylinder should be selected at high temperature; in the case of corrosion, the anti-corrosion FESTO cylinder should be selected. . In the case of dust or other severe conditions, the piston rod must be attached to the end of the piston rod to install a dust cover. When no pollution is required, it is necessary to use a non-oiled or oil-free lubricating rodless cylinder.
Nowadays, there are some methods for selecting the type. When the user selects the model, he can choose according to his own needs, which is very convenient for himself to choose.
