What are the market advantages of domestic diaphragm couplings?

Coupling is an important accessory in industrial production, and its service life is also very long. So, what is the market advantage of domestic diaphragm coupling? The following is the content about it brought by the editor, I hope we can have The harvest!

Selection and professional standards for domestic diaphragm couplings

There are many options for domestic diaphragm couplings. Generally, there are claw couplings, diaphragm couplings, elastic sleeve pin couplings, permanent magnet couplings, plum-shaped elastic couplings, and claw couplings. Coupling, nylon internal gear coupling.Each has its own benefits, and the following information is available for reference in terms of selection.

The center sliding block of the claw coupling is made of cloth bakelite or polyurethane. It is light in weight, simple in structure, convenient in equipment, and low in price. It is often used in small power occasions. It is suitable for small torque, high speed, and no The two shafts are connected with a sharp impact.The transmission torque of nylon slide block is small, but it is more suitable for high-speed operation and does not need to be smooth. The code name of the water pump profession is Bl104.

The diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two shafts connected. It is a high-function flexible coupling with metal elastic elements. It does not need to be smooth, has a compact structure, high strength, and long service life. There is no rotating gap, not affected by temperature and oil pollution, and has the characteristics of acid resistance, alkali resistance, and corrosion resistance. It is suitable for shafting transmission in high temperature, high speed, and corrosive medium working conditions. It is widely used in shafting of various mechanical equipment.

This coupling is suitable for flexible transmission between shafts, allowing large axial radial displacement and angular displacement, and has simple structure, convenient repair, simple disassembly and assembly, low noise, small loss of transmission effectiveness, and long service life Equivalent, the semi-coupling is made of fine casting, the shaft hole and the keyway are drawn and molded, and the inner gear coupling elastomer jacket can be selected from various hardness synthetic rubber grease rubber according to the user's application requirements; reinforced cast nylon elastomer And other information.

The pin of the elastic sleeve pin coupling is covered with a rubber ring, which has elasticity and ability to compensate axis displacement, but when the relative angular displacement is large, it is easy to wear, simple structure, convenient equipment, simple replacement, small size, light weight , The transmission torque is large, and it is widely used in various rotary pumps. The professional standard for water pumps is Bll01

Structural features and strengths: Compressible elastomer design, convenient assembly, reliable function, no special equipment is required; because the shearing elastic body design is selected, the coupling has the common anti-vibration and impact resistance capabilities, and the change function is superior ;Three kinds of elastomers with different materials are available for selection to meet the needs of different application occasions, and there are two ways of one-body and two-body

The permanent magnet coupling is a new type of coupling that connects the prime mover and the working machine through the magnetic force of the permanent magnet. It does not require a direct mechanical connection, but uses the interaction between the rare earth permanent magnets and can be penetrated by the magnetic field. The transmission of mechanical energy is carried out through a certain space interval and the characteristics of the material data.The appearance of the magnetic coupling completely solves the leakage problem of the dynamic seal in some mechanical equipment.

The plum-shaped elastic coupling is mainly suitable for frequent starting, forward rotation, medium and high speed, medium torque and high reliability operation occasions, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump , Fan, etc.The plum-shaped elastic coupling has the following characteristics: stable and reliable operation, excellent vibration reduction, buffering and electrical insulation functions, simple structure, small radial dimension, light weight, and small moment of inertia, suitable for medium and high speed applications.

The center sliding block of the claw coupling is made of cloth-filled bakelite or polyurethane, which is light in weight, simple in structure, convenient in equipment, and low in price. It is often used in low-power applications: the raw material of the L rubber coupling is powder metallurgy product model: L-035 050 070 075 090 095 099 100 110 150 CL rubber coupling raw material is cast iron Product model: CL-090 095 099 100 110 150 190 225

Market advantages of domestic diaphragm couplings

The planning and manufacturing of domestic diaphragm couplings has reached the appropriate level with foreign countries, and has accumulated a lot of application achievements in the field of high speed and high power.Domestic OEMs and end users have already gained widespread recognition.Judging from the previous application experience, the choice of domestic diaphragm coupling has at least the following advantages:

(1) The technical support is timely and abundant, and the coupling selection can be matched with the unit to achieve the best application effect.Selecting domestic manufacturers' products, the two sides can communicate directly during the unit planning process, and have sufficient negotiations on functional parameters and structural dimensions.And this kind of communication is more direct and useful, which can save time and improve planning power. (2) The product price advantage is significant, especially the price of spare parts is very low.Under normal circumstances, the price of domestic diaphragm couplings is only a fraction of the imported price.For host manufacturers, it is possible to reduce package costs, and for end users, they can quickly obtain technical support and spare parts supply at very low prices in subsequent operations. (3) After-sales service has a quick response, especially the supply cycle of spare parts has been greatly shortened.Domestic suppliers have a short manufacturing supply cycle, and can respond sensitively to changes in demand, and can respond quickly to emergency needs.In recent years, the service awareness of professional manufacturers has been significantly strengthened, and service capabilities and service quality have continued to improve.
