ã€Network News】 Any machinery and equipment, the use of the installation before installation is a very important step, the installation of a direct impact on the normal operation of machinery and equipment and service life. Xiaobian now to say that the rotor pump installation steps and pay attention to points. As the pump does not come with motor, adjusting device and base plate and other accessories, so install the pump, according to the installation diagram and the previous technical parameters of the table in the motor power and maximum speed, select the appropriate motor (the best choice of tune Speed ​​motor) model and a flexible coupling, and in accordance with the pump and the center of the selected motor high, preparation of a stainless steel base plate. In the installation of rotor pump, should also pay attention to several issues: 1, the pump and the motor shaft connection, should first correct the level and ensure that both coaxial rear coupling can be installed, otherwise, will cause the parts damage. 2, because the pump is a fixed capacity pump, displacement per revolution, once the process for some reason to stop working and the pump is still working, then the pump pressure will rise indefinitely, leading to seal leaks, mechanical damage The accident occurred, therefore, must take effective preventive measures. Example 1: With the upper and lower processes should be chain, when the next process downtime, stop the pump at the same time. Example 2, the output of the pipeline can be installed safety valve and overpressure circuit system, once over-pressure will be automatically unloaded. 3, if the pump control valve, it can only be installed in the pump inlet pipe, the outlet pipe should not be installed control valve, easily lead to over-pressure error. 4, after all the installation is completed, should conduct a comprehensive inspection, including mechanical parts, electrical wiring, etc., and then hand pump the rotation of 3 to 5 turns to observe whether there is any stuck or loose phenomenon until normal, and then through Is the electric test run, if found abnormal, due to stop overhaul, paternity everything after the normal delivery.
