R type fiber fabric compensators
Applications of R type fiber fabric compensators:
1. Bellows, welded or convoluted (formed) are used in a large number of industrial applications. Below you will find a few;
2. Load cells; A load cell deforms if a certain load in the form of a pressure or a strain is imposed on it. This deformation is then detected by a strain gauge through which a low voltage direct current is flowing. The change in voltage is detected and made visible on a control panel. To protect this strain gauge from outside damages or weather influences a bellows is mounted over the gauge to protect it from outside influences.
3. Vacuum interrupters; For the switching of very high voltages in transformer stations sparks should be avoided. To prevent any danger that the surrounding atmosphere will explode, oxygen has to be removed in the area where the sparks occur. This can be done by sealing the spark area completely. Bellows are used to seal such confined volumes and the inside of the bellows is evacuated or filled with an inert gas.
4. Mechanical Seals; These are mostly used to close the inside of a pump from the outside world to prevent leakage. For that purpose, a mechanical seal is mounted on the pump shaft. As the pump shaft is turning, there has to a rotating sealing element consisting of a stationary and a rotating ring. To enforce sufficient pressure on the two rings one is fitted with a spring. This spring can also have the form of a diaphragm (welded) bellow.
5. Pressure gauges: If the pressure of aggressive fluids or gases has to be measured, the gauge has to be isolated from the flow. For critical applications a diaphragm sealing is used instead of a bourdon tube in the gauge. This gives more security that the aggressive media will not leak. The diaphragm is a self contained sensor, transmitting the displacement to the measuring device.
6. Sensors: In this application diaphragm or convoluted bellows are completely sealed and filled with a certain gas. Two electrical poles are penetrating the inside of the bellows. By varying the current of those two poles the temperature inside the bellows can be regulated. The expansion or contraction of the bellows is used as an actuator to control a certain movement.
7. Valve Sealing: A bellows is used between the housing and the rising stem to seal the inside completely from the outside world. In Europe this is of particular importance as regulations such as TA Luft prohibit any leakage.
In order to make fiber fabric compensators achieve available effect in pipe and all mechanical performance play their right role and extend its use life, please make installation according to the requirements as follows:
1. Fiber fabric compensators should be installed in pipe in natural conditions and the product distorton by contrived factors should be made in installation, so the products will avoid from early damage and weaker application effect.
2. When fiber fabric compensators is installed to connect with flange, screw of bolt should stretch to the outside of flange to prevent the rubber (fabric) ball from being scraped by whorl tip. The bolt on the face of each flange should be screwed down equably by thread and it is required that all the degree of tightness should be as consistent as possible. In bad conditions, spring gasker can be added except flat gasket to avoid nuts from loosing.
3. The tolerance of installation sizes in various should accord to the following list.
4. The support in the joint should be kept before the installation and will be entirely taken off after tightening bolts to guarantee the reasonable installation and make various physical mechanical performance play right role.
