Rotary damper is mainly aimed at damping control of the motion of some parts in the direction of rotation, ensure that the rotary motion is achieved in soft, silent and safe environment. Rotary damper according to the rotation angle, rotary damper can be divided into more than 360 degrees circular rotation angle and limit rotation angle. Different types according to the installation type of the product, rotary damper can be divided into Barrel Damper, Vane Damper, stop damper, Gear Damper , Disk Damper and Shaft Damper etc. ABD rotary dampers are used to dampen drives, control speed, and many other applications.
Our rotary dampers are widely used in automobile interior decoration, household electric appliances, furniture, invisible screens, theater seats and bathroom products, etc. ABD damper is conducive to performing structural movement in soft, silent and safe environment, mitigating impact load, avoiding strike damage, prolonging mechanical life, reducing noise disturbance, improving product quality and improve customer satisfaction.

Centrifugal pumps are widely used in various fields of industry. Centrifugal pumps use the impeller rotation to make the centrifugal force generated by the water work. However, there are many kinds of centrifugal pumps on the market, and the standards vary. This article will teach you how to choose the most suitable product from a professional perspective.
(1) determining the flow and pressure head <br> <br> transport amount of liquid delivery system is generally defined as the production task, if the flow fluctuations within a certain range, the maximum flow rate should be selected considering the centrifugal pump. According to the arrangement of the delivery system piping, the Bernoulli's equation () is used to calculate the required head pressure at the maximum flow rate.
(2) select the type and model of pump <br> <br> first determine the type of pump delivery depending on the nature of the liquid and operating conditions, and then press the determined flow rate and pressure head He Qe selected directory from the sample pump or product The appropriate model. Obviously, the flow rate and pressure head provided by the selected pump are not necessarily completely in line with the required flow Qe and pressure head He, and taking into account changes in operating conditions and with a certain margin, the flow rate of the selected pump and The indenter can be slightly larger, but the efficiency of the corresponding pump under this condition should be relatively high, ie the coordinate position of the point (Qe, He) should lie under the HQ curve corresponding to the high efficiency range of the pump. After the model is selected, various performance parameters of the pump should be listed.
(3) Measurement of the pump when the delivery <br> <br> shaft power density of the liquid is greater than the density of water, may be () of the pump shaft power calculation.
Of course, there are many products to meet the above technical requirements. When purchasing, we should also consider the price of the centrifugal pump and the reliability of the use; the geographical location, strength, and service word of service of the supplier.
