Maintenance, measurement and adjustment methods of pump and motor coupling

　　The rotation centers of the two shafts of the coupling connected to the pump and the motor should be strictly concentric.During the installation process, the coupling should be aligned and centered, otherwise great stress will be generated on the coupling, which will seriously affect the normal operation of the shaft, bearings and other parts on the shaft, and even cause vibration or damage to the entire machine tool and foundation.When installing a new pump, the verticality between the end face of the coupling and the shaft can be uncontrolled, but when installing an old pump, please check carefully. When you find that the vertical direction is not vertical, look for the equipment being installed, and install the driver first. The machine (pump) keeps its shaft in a horizontal position, and then installs the active machine (motor), so you only need to adjust the active machine when looking for a suitable machine. Yes, add an adjustment surface adjustment method under the feet of the movable machine (motor).

　　Two commonly used measurement and adjustment methods in the process of overhaul are introduced.

　　1) Use a knife ruler and an intubation ruler to measure the different cores of the coupling, and use a wedge-shaped gap rail or an intubation ruler to measure the non-parallelism of the coupling end surface.This method is suitable for low-speed, low-precision flexible connection equipment.

　　2) Measure the concentric and non-parallel states of the two couplings with dial indicators, bezels or special alignment tools.This method is suitable for high-speed, rigid connection, and high-precision rotating equipment.

　　The coupling does not seem to be much, but it is an important part of industrial equipment.The coupling industry in my country is basically composed of three parts: couplings, vehicle couplings and couplings.Among them, the market share of automotive couplings reaches 60%, and the couplings are composed of industrial general-purpose, special-purpose, and special-purpose couplings, with market shares of 18%, 12%, and 8% respectively; coupling devices account for 2% of the market share .

　　The coupling has good balance performance and is suitable for high-speed occasions (speed up to 30000 rpm), but it cannot handle large deviations, especially axial deviations.Compared with other servo couplings, large eccentricity and deflection angle will produce greater bearing load.Another concern is the failure of plum coupling.Once the quincunx elastic gasket is damaged or fails, the torque transmission will not be interrupted, and the metal claws of the two shafts mesh together to continue to transmit the torque, which is likely to cause problems in the system.It is one of the main advantages of this coupling to choose the appropriate plum elastic baffle material according to the actual application.

　　The company can provide various elastic materials for plum partitions, with different hardness and temperature resistance.Let customers choose the right material to meet the performance standards of the actual application.Strictly ensure the coaxiality of the two shafts, so that no unilateral load is generated during operation, so as to maintain balance and reduce vibration. The requirements for concentricity of different types of installation are 0.2.Generally speaking, it is good to loosen and tighten the screws, you can also choose the coupling with keyway! Use the key to connect to the shaft end of the motor, screw or other shaft, even if the screw is not tightened.The coupling has a variety of structural forms, a wide range of applications and a variety of material options.It is one of the most commonly used models in elastic couplers.Commonly used coupling materials are gray cast iron, cast steel and aluminum alloy.The coupling has the advantages of simple structure, no lubrication, convenient maintenance, convenient maintenance, maintenance-free, and long-term continuous operation.High-strength polyurethane elastic elements are wear-resistant and oil-resistant, have large carrying capacity, long service life, and are safe and reliable.The utility model is stable and reliable in operation, and has good damping, buffering and electrical insulation properties.It has strong axial, radial and angular compensation capabilities.The utility model has simple structure, small radial size, light weight and small moment of inertia, and is suitable for medium and high speed occasions.Couplings are widely used in large-scale machinery and equipment and are indispensable.Today’s editor will briefly introduce it here.With the continuous development of the economy and the rapid progress of society, people have been fully prepared for the era of science and technology.Perhaps we vaguely remember the inefficiency of the original labor force. Later, with the gradual development of society, people saved more time to do their own things.Land is a source of livelihood for the farmers. Spring and autumn are harvest seasons each year. But before that, the land needs to be irrigated and water pumps are often used.Today, let us talk with you about the coupling on the top of the pump.Let us see how to choose a plum blossom coupling! The main products produced by the company are: star elastic coupling, tire coupling, drum coupling, plum blossom coupling, shell coupling, slider coupling Shafts, roller couplings, diaphragm couplings, elastic pin couplings, etc.
