Today, the spread and spread of falling sensation plays an important role in the operation of plant equipment and mechanical equipment, and the planning of industrial valve plan is the top priority
。 In recent years, in the field of forming and processing, the continuous improvement and enhancement of mechanical properties are always accompanied by the addition of equipment speed, cutting rate and impact force. This means that it is necessary to convey a sensational addition to the surrounding environment. This sensation needs to be effectively controlled, and it is necessary to plan a suitable industrial valve plan.
In the industrial valve plan, the purpose of using vibration isolation equipment for machinery and equipment is to decline and shake. Its mission is to control the machine movement of flexible equipment within the allowable range of machine operation. The selected isolation equipment must have sufficient damping ability.
The isolation power in the industrial valve plan largely depends on the connection (matching ratio) between the speed/impact rate of the machine and the natural vibration frequency of the isolation equipment. Generally speaking, the lower the natural vibration frequency of the isolation equipment, the greater the ratio between the forced vibration frequency and the natural frequency, that is, the higher the power of the isolation equipment. When the variable n is greater than √ 2, isolation is useful. The isolation effect cannot be obtained when the frequency coefficient is lower than. On the contrary: its sensation will certainly increase. Generally speaking, the ratio should be adjusted between 3 and 4. From the perspective of skills, 3 is the lowest share, and 4 is the highest share from the perspective of economy. The frequency ratio greater than 4 cannot be adjusted economically, because the cost of data will exceed the share of the isolation effect.
In the industrial valve plan, attention should also be paid to the physical characteristics of the impact, that is, the durability, directness and magnitude of the impact. The purpose of shock isolation is to change the forced frequency. The forced frequency is to give a sharp impulse to the longer lasting pulse, along with its small residual force. Different from the regular sensationalism, the equipment with tension spring is sensationalized according to the inherent excitation frequency of the isolation equipment, rather than the number of impacts. The residual force transmitted by the isolation equipment will gradually become smaller and smaller. The longer the natural sensational period is, the smaller the natural frequency of the equipment with tension spring will be.
