What should be paid attention to when installing the electric butterfly valve on the pump?
Electric butterfly valve is a common and important valve element. It is widely used in cars, planes and other transportation vehicles. So as long as the local people need to go to the electric butterfly valve, they will choose the electric butterfly valve. What aspects of its application in pumps should be paid attention to? When it comes to shock absorbers, we have to say that they have the effect of shock absorption and sound insulation.
But this time I will not talk about these things. What I want to talk about is how to install the shock absorber on the pump and what are the choices. Selection of shock absorber: the raw materials are generally neoprene and natural rubber; Generally, compact shock absorbers are used. For pumps with light weight, shear shock absorbers can be used; Compared with the spring damper, the vibration isolation function of the damper is relatively poor. Adding a lazy base: In order to satisfy the stricter oscillation system standard, when adding a lazy base, it is undoubtedly the best choice to use a tension spring damper. To the end.
In fact, the shock absorber is not the best choice for the water pump, but the tension spring shock absorber. Although the former is better in sound insulation, the high amplitude oscillation of the water pump is really not suitable, and the tension spring shock absorber can just make up for this. The shock absorption function of the shock absorber shall be judged by the shock absorption test.
Damping test is generally only carried out when the shock absorber is newly designed and manufactured, and it is not necessary to test the shock absorber one by one after mass production; It only needs to carry out the type test. However, for particularly important shock absorbers, or shock absorbers that must be conditioned in the shock absorption test to meet the technical requirements, they should be tested one by one. The vibration reduction experiment should be carried out on the whole machine, so the experimental condition is the practical working condition; The vibration reduction experiment can also be carried out on a special vibration reduction test bench, that is, to simulate the practical working conditions, artificially make the vibration source, and compare the difference between the shock absorber without the shock absorber and the shock absorber installed in the future, so as to identify the advantages and disadvantages of the shock absorber.
Features of Dongfeng shock absorber
There are two types of shock absorbers: fixed shock absorber and rotary shock absorber. Fixed vibration damping refers to taking vibration damping measures for fixed parts, such as base shock absorber; Rotating vibration damping refers to taking vibration damping measures on rotating bodies, such as rotor vibration damper, bearing vibration damper, etc. Fixed vibration damping mainly refers to base vibration damping, which is widely used.
