These different types of pneumatic butterfly valves have different applications in different industries. What should we pay attention to when rubber pneumatic butterfly valve devices are used in pumps?
Rubber pneumatic butterfly valve is a common and important shock absorption element. It is widely used in vehicles such as automobiles and airplanes. So rubber pneumatic butterfly valve will be selected from the center of the pneumatic butterfly valve. What aspects of its application in pumps need attention?
When it comes to rubber shock absorbers, we have to talk about their shock absorption and sound insulation effects. But this time I won't talk about it. What I want to talk about is how to install a rubber damper on the pump and what options are available. Selection of rubber shock absorber:
1. The material is generally neoprene, natural rubber;
2. Generally, compact rubber shock absorbers are used. For pumps with lighter weight, shear rubber shock absorbers can be used; 3. Compared with spring shock absorber, the isolation performance of rubber shock absorber is relatively poor.
Installing an inert base: In order to meet the stricter vibration system specification, it is undoubtedly the best choice to use a spring damper when installing an inert base.
In the final analysis, the rubber shock absorber is not the best choice for the water pump, but the spring shock absorber. Although the former is better at sound insulation, the high amplitude vibration of the water pump is really not suitable for the rubber, and the spring shock absorber can exactly complement this.
The shock absorption performance of the shock absorber shall be verified by the shock absorption test. The vibration reduction experiment usually stops only when the shock absorber is newly designed and manufactured, and it is not necessary to stop the experiment on the shock absorber one by one after mass consumption; Just stop the typing experiment. However, for particularly important shock absorbers, or shock absorbers that need to stop conditioning in the shock absorption test before reaching the technical request, they should be tested one by one. It is better to stop the vibration reduction experiment on the whole machine, so the experimental condition is the practical working condition; The vibration reduction experiment can also be stopped on a special vibration reduction test bench, that is, to imitate the practical working conditions, artificially manufacture the vibration source, and compare the difference between the shock absorber without it and the shock absorber installed, so as to evaluate the advantages and disadvantages of the shock absorber.
According to different conditions, vibration sources can be manufactured by various excitation offices, such as the reciprocating displacement excitation generated by the eccentric rotating to drive the slider, the centripetal force excitation generated by the unbalanced rotor, the compressed air blower, the loudspeaker, the electromagnetic induction, or the special vibration table, etc. The parameters to be measured during vibration test include frequency, amplitude, velocity, acceleration, etc., and sometimes the stress or strain of some parts of the machine. Different industrial departments and different machine products have different requirements for vibration.
Rubber pneumatic butterfly valve has a great application in our consumption. It has made remarkable contributions to our shock absorption. So the rubber pneumatic butterfly valve installed on the pump is also very sophisticated. I hope the above content can help you. Our information today is over, thank you!

What are the steps for welding pneumatic butterfly valves
Pneumatic butterfly valves are used as compensation elements, sealing elements, connecting elements, shock absorption elements and other important components in engineering technology, and are widely used in aerospace, petrochemical, mining electronics, machinery and shipbuilding, medical and health, textile electronics, energy construction, metallurgy and other fields.
When the pneumatic butterfly valve is used as a highly flexible pipeline connecting metal equipment, when connecting with other equipment, welding method is mostly used. In the process of welding, we often use the five step welding method. Today, I will lead you to understand the detailed implementation of the five step welding method.
1. Nozzle size. During welding, the pipe length shall be measured first, and then the pipe knife shall be used to cut the pipe size.
2. Clean the pipeline. Due to the metal nature of the pipe, some waste slag will be generated due to oxidation in the pipe, and some waste slag will affect the welding effect. Therefore, before welding, we should use emery cloth or paper to grind away the waste slag in the pipe.
3. Clean the fittings with a pipe brush. Cleaning the fittings ensures that the welding hose is bonded to the tin plating.
4. Control the welding time. Generally speaking, the length of the weld bead you need depends on the length of the solder.
5. Use flare heat pipe. The torch heat pipe is mainly used to ensure the average heating at the welding point of the pipe. Note that when using the torch, ensure that the flame is close enough to cover the diameter of the whole pipe.
The control of welding steps of pneumatic butterfly valve is helpful for users to stop welding of pneumatic butterfly valve more safely. Although the welding of pneumatic butterfly valve is not easy, the work will be better and better as long as the relevant knowledge is carefully studied and the operation is carefully stopped.
