Use and maintenance of diaphragm coupling accessories

Author: 11 Published: 2020-10-21

Diaphragm couplingThe composition is composed of several sets of stainless steel diaphragms or thin plates, and then use bolts to stagger the two halvesCouplingMake the connection.Each group of diaphragms is made up of several pieces. The diaphragms are divided into connecting rod type or different shapes of the whole piece type. The diaphragm is fastened to the shaft sleeve with a pin, which generally does not cause looseness or the diaphragm and the shaft sleeve. The recoil between.

Diaphragm couplingAccessories

Diaphragm couplingThe structure is relatively streamlined, two and a halfCoupling, A set of diaphragms, several sets of bolts.Among them, the diaphragm is one of the main structures of the diaphragm coupling, but many people regard the diaphragm as an accessory because the diaphragm is a consumable product.

The bolts, nuts and elastic pads in the diaphragm coupling can be called the accessories of the diaphragm coupling. They are the same as the diaphragm and need to be regularly inspected and replaced.

1. First talk about the diaphragm, because it is made of stainless steel and has good toughness. When it is applied to machinery and equipment, it will be damaged after a long period of use. Many diaphragm couplings can be used for more than 2 years, but Some companies have suffered damage to varying degrees after applying the diaphragm coupling a week later.

The service life of the diaphragm also depends on the working conditions of the specific application, whether the installation is in place, whether the torque is overloaded, etc. These are important factors that affect the service life of the diaphragm.

2. Bolts, nuts and elastic pads will show different conditions of wear, breakage and fall during work and operation, especially the bolts, which will cause the bolts to bend and break due to excessive torque. Common.Like diaphragms, their service life does not have a fixed value, but the general product quality has a promise of quality assurance, which can save you a lot of worries.

Application and maintenance

1. Before machinery and equipment, clean the end faces of the two shafts of the diaphragm coupling and check the overall coordination conditions such as the key grooves on the end faces.

2,Diaphragm couplingAfter the equipment is installed, work normally for a shift, and then start to check all the screws. If you notice that the screws are loose, you must tighten them. Repeat this for multiple shifts to ensure that they will not loosen.

3. In order to prevent the fretting wear of the diaphragm during high-speed operation, and further cause the diaphragm bolt hole to show microcracks and damage, the diaphragm can be coated with a solid lubricant such as molybdenum disulfide or the diaphragm A method of anti-friction coating treatment on the surface of the sheet.

4. Long-term overload applications and actual operation risks should be prevented;

5. During the operation, check whether the diaphragm coupling has abnormal phenomena regularly, and repair it in time if any abnormal phenomena occur.
