2. Then put the smaller tube inside the larger tube, the thickness is just right. If it is idle and unstable, you can wrap a circle of electrical tape before inserting it. Pay attention to at most one circle, otherwise it will not be inserted.
3. Then there is this magical muzzle in front of the silencer. It's actually quite simple. It's the cover behind the TD original laser aiming, and it can be inserted into the thin tube just by wrapping several circles of electrical tape.
4. finally, paint, and add the effect diagram to the finished product.

Question 4: How to make simple muffler Many industrial and mining enterprises use a large number of low-pressure boilers below .13Mpa, and there are also a large number of low-pressure thermal devices in the thermal system of power stations, such as back-pressure steam turbines, deaerators and auxiliary air extractors. The exhaust pipe of the above equipment requires a muffler with convenient structure and more convenient installation. Our factory has designed special deaerator series, back pressure steam turbine series and other series products for different noise elimination objects, which can meet the requirements of users. Both enterprises you mentioned can produce.
question 5: how to make silencers? I'm glad to answer your question. There are many kinds of silencers, but according to their silencing mechanism, they can be divided into six main types, namely, resistive silencers, reactive silencers, impedance compound silencers, micro-perforated plate silencers, small-hole silencers and active silencers.
the resistive muffler mainly uses porous sound-absorbing materials to reduce noise. The sound-absorbing material is fixed on the inner wall of the airflow channel or arranged in the pipeline in a certain way, which constitutes a resistive muffler. When the sound wave enters the resistive muffler, part of the sound energy rubs in the pores of the porous material and is converted into heat energy to be dissipated, so that the sound wave passing through the muffler is weakened. A resistive muffler is like a pure electrical resistance circuit, and the sound-absorbing material is similar to a resistor. Therefore, people call this muffler a resistive muffler. Resistive muffler has a good effect on middle and high frequency noise elimination, but a poor effect on low frequency noise elimination.
the reactive muffler is composed of tubes and chambers with abrupt interfaces, which seems to be an acoustic filter. Similar to an electrical filter, each chamber with tubes is a mesh of the filter, and the air quality in the tubes is equivalent to electrical inductance and resistance, which is called acoustic quality and acoustic resistance. The volume of air in the chamber is equivalent to the electrical capacitance, which is called acoustic compliance. Similar to an electrical filter, each cell with a tube has its own natural frequency. When sound waves with various frequency components enter the first short pipe, only some frequencies near the natural frequency of the first mesh can reach the second short pipe mouth through the mesh, while other frequencies can't pass through the mesh and can only be reflected back and forth in the small room. Therefore, we call this structure with filtering function for sound waves an acoustic filter. The noise of some frequency components can be filtered by selecting appropriate tubes and chambers to achieve the purpose of noise elimination. Reactive muffler is suitable for eliminating middle and low frequency noise.
the resistive structure and the reactive structure are combined in a certain way to form an impedance compound muffler.
Microperforated plate silencers are generally made of pure metal sheet with a thickness less than 1mm, and the sheet is perforated with a drill with a hole diameter less than 1mm, and the perforation rate is 1%-3%. By choosing different perforation rate and different cavity depth, the spectrum performance of muffler can be controlled, so that it can obtain good noise elimination effect in the required frequency range.
the structure of the small hole muffler is a straight pipe with a closed end, and many small holes are drilled in the pipe wall. The principle of orifice muffler is based on the frequency spectrum of jet noise. If the total area of the nozzle is kept unchanged and many small nozzles are used instead, when the airflow passes through the orifice, the frequency spectrum of jet noise will move to high frequency or ultra-high frequency, which will obviously reduce the audible sound components in the frequency spectrum, thus reducing the interference and harm to people.
the basic principle of the active muffler is that in the original sound field, electronic equipment is used to generate another sound wave which is equal in magnitude and opposite in phase to the original sound pressure, so that it can cancel out the original sound field in a certain range. This muffler is an instrument device, which is mainly composed of microphone, amplifier, phase shifter, power amplifier and speaker.
