Application range of rubber pneumatic butterfly valve for fan
Application range of rubber pneumatic butterfly valve:
1、 The vibration source belongs to the vibration isolation and noise control of high frequency rotating mechanical equipment. For example: for fans, water pumps, generator sets, air conditioning hosts, etc., rubber pneumatic butterfly valves should be used when the rotation frequency of mechanical equipment should be greater than 1000 revolutions;
2、 The impact frequency of stamping equipment should avoid the natural frequency of rubber pneumatic butterfly valve. For example, punch, die-cutting machine, press, etc; 3、 Since rubber shock absorption has the function of vibration reduction in all directions, pneumatic butterfly valves are widely used in automobiles, aerospace and navigation; 4、 Other mechanical equipment.
At the same time, due to the characteristics of the product itself, there are many places where the rubber products industry is very inappropriate. First of all, rubber will become brittle at minus 30 degrees, and lose its own elastic deformation. At this time, it will basically not play a role in vibration reduction. Therefore, in an excessively cold environment, do not use rubber vibration reduction products to avoid the expected effect. Rubber also cannot withstand high temperatures. Just go beyond 75 degrees Celsius, its internal structure will change, and its elasticity will disappear completely. Of course, it will no longer have any vibration damping function. If the temperature continues to rise, it may be extinguished. Therefore, if you are in a very high temperature environment, you should never use a rubber shock absorber, otherwise, it will not only fail to play the expected role in reducing vibration, and may cause accidents.
According to the above explanation, we can conclude that we should use different rubber shock absorbers in different places, and different rubber shock absorbers will produce different effects. However, no matter what products we use, we should fully understand the characteristics of the products in the early stage. As long as we choose the right products and use the right places, the products can really serve us.

4. Investigate item 4 in the flow chart of liquid physical property checking. When the conductivity of liquid changes or is uneven, the zero point will change when it is stationary, and the output will shake when it flows. Therefore, the flowmeter should be located far away from the injection point or downstream of the chemical reaction section of the pipeline, and the flow sensor should preferably be installed upstream of these places. If the liquid contains solid phase, or impurities deposit on the inner wall of the measuring tube, or scale on the inner wall of the measuring tube, or the electrode is polluted by grease, etc., zero point change may occur. Because the scaling on the inner wall surface and the degree of electrode pollution cannot be completely similar and symmetrical, the balance set by the plant's initial withering will be destroyed. Active measures should be taken to remove dirt and scale deposits; If the zero partner changes little, you can also try to reset it.
