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 electric butterfly valves, we have to say that they have the effect of vibration reduction and sound insulation.
But this time, we will not talk about these, but about the installation of electric butterfly valve on the pump, and what to choose. Selection of electric butterfly valve: the raw materials are generally neoprene rubber and natural rubber; Generally, the compact electric butterfly valve is selected. For the lighter pump, the shear electric butterfly valve can be selected; Compared with the tension spring electric butterfly valve, the vibration isolation function of the electric butterfly valve is relatively poor. Add lazy base: In order to satisfy the stricter oscillation system standard, when adding lazy base, it is undoubtedly the best choice to use the tension spring electric butterfly valve. To the end.
In fact, the electric butterfly valve is not the best choice for the water pump, but the tension spring electric butterfly valve. Although the former is better in sound insulation, the high amplitude oscillation of the water pump is really not suitable, and the tension spring electric butterfly valve can just make up for this. The shock absorption function of the electric butterfly valve shall be judged by the shock absorption test.
The vibration reduction test is generally conducted only when the electric butterfly valve is newly designed and trial produced, and it is not necessary to test the electric butterfly valve one by one after mass production; It only needs to carry out the type test. However, for the electric butterfly valves that are particularly important or must be conditioned in the vibration reduction 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, compare the future differences between the electric butterfly valve and the electric butterfly valve, so as to identify the advantages and disadvantages of the electric butterfly valve.
Features of Dongfeng electric butterfly valve
The position where the electric butterfly valve is located can be divided into two types: fixed vibration damping and rotary vibration damping. Fixed vibration reduction refers to taking vibration reduction measures for fixed parts, such as electric butterfly valve of engine base; Rotating vibration reduction means that vibration reduction measures are taken for rotating bodies, such as rotor electric butterfly valve, bearing electric butterfly valve, etc. Fixed vibration damping mainly refers to base vibration damping, which is widely used.
