How to silence a silencer and what is the principle of silencer?

How does a silencer do it? The foreigner violently cut it, only to find that the internal structure is so precise!

Muffler principle:For air flow pipes with noise propagation at the same time, noise reduction devices such as pipes and elbows with sound-absorbing linings or pipes with sudden changes in cross-sectional area and other sound impedance discontinuities can be used to attenuate or reflect back the noise in the pipes.

There are many types of mufflers, but the muffler mechanism can be divided into six main types, namely resistive mufflers, resistant mufflers, impedance composite mufflers, micro-perforated plate mufflers, small hole mufflers and active mufflers.

Structure:

Depending on the space under the car, the muffler cover can be machined into a tile shape or rolled into a pot. The outer cover of the pot muffler is to shape the outer cover material with a round mandrel and snap it together or install it as a whole with a welded connection, and the welded parts are loaded into the interface. The pot muffler consists of an inner tube, a steering elbow and an intermediate base plate, after which the outer base plate is connected to the outer cover by slotting or welding.

When the space under the car is complex and it is difficult to install a pot muffler, a deep-drawn tile muffler can be used. It can be made in almost any form. The total volume of the muffler for the car is 8 times 12 times the engine displacement.

Silenced is the elimination of sound by some means of audio processing.

Now silencing is also used on flat surfaces. For example, the leading "Most **", if there are some discordant things in the content of individual columns, they will be replaced by silence.

The word silence is also a sign of respect for people and avoids unnecessary trouble.

Silencing is a unique phenomenon that usually appears in the background sound of radio or television programs.

The muffler principle is that the exhaust pipe is made up of two pipes of different lengths, which separate and then meet. Because the length difference between the two pipes is equal to half of the wavelength of the sound waves emitted by the car, the two columns of sound waves cancel each other and weaken the sound intensity when they interfere when superimposed, so that the sound is reduced and the sound is suppressed.

Resistive mufflers are mainly used to reduce noise by using porous sound-absorbing materials. A resistive muffler is formed by fixing the sound-absorbing material on the inner wall of the airflow channel or arranging it in the pipe in a certain way. When the sound wave enters the resistive muffler, a part of the sound energy is rubbed in the pores of the porous material and converted into heat energy to dissipate, so that the sound wave passing through the muffler is weakened.

Resistive mufflers are like pure resistive circuits in electricity, and the sound-absorbing materials are similar to resistors. Therefore, this muffler is called a resistive muffler. The resistive muffler has a good silencing effect on medium and high frequencies, and a poor attenuation effect on low frequencies.

The resistant muffler is composed of a combination of a tube and a chamber at a mutation interface, like an acoustic filter, similar to an electrical filter, each chamber with a tube is a mesh of the filter, and the air quality in the tube is equivalent to the electrical inductance and resistance, which is called sound mass and acoustic resistance. The volume of air in the chamber is equivalent to the electrical capacitance, which is called sonic.

Similar to electrical filters, each tubed chamber has its own natural frequency. When sound waves containing various frequency components enter the first spool, only certain frequencies near the natural frequency of the first mesh can pass through the mesh to reach the second spool mouth, while sound waves of other frequencies cannot pass through the mesh.

It can only be reflected back and forth in the chamber, so this structure that has a filtering function for sound waves is an acoustic filter. Select the appropriate tubes and chambers for combination. It can filter out the noise of some frequency components of the ear to achieve the purpose of silencing. Resistant mufflers are suitable for eliminating mid- and low-frequency noise.

Hello, Lianyungang Huabo Machinery Equipment **** muffler (muffler) is a device that prevents sound transmission and allows air flow to pass through, and is an important measure to eliminate aerodynamic noise. The silencer is a noise reduction device installed on the airflow channel of aerodynamic equipment (such as blowers, air compressors, boiler exhaust ports, generators, water pumps and other equipment with high noise from exhaust ports) or in the intake and exhaust systems. There are many types of silencers, but when it comes to the silencer mechanism, they can be divided into six main types, namely resistive silencers, resistant silencers, impedance complex field voltive silencers, micro-perforated plate silencers, small hole silencers and active silencers.

The method of making a silencer is as follows:

1. Measure the muzzle diameter of the paintball gun. Simply place one end of the tape measure on the muzzle and measure a portion of the muzzle width directly, which will give you a very accurate measurement. Measure the distance of the gun body. Use a tape measure or ruler to measure the entire barrel of the gun, not just the muzzle.

2. Buy a 1 inch (cm) PVC pipe and a 2 inch (cm) PVC pipe. Inches refers to the width of the diameter length of the pipes that will serve as the frame for the silencer. Cut 10 inch PVC pipe with a length of 2 inches.

You can use a hand saw, hacksaw or other plastic pipe cutter, or a miter saw. Make a simple 10-inch measurement and mark it with a pencil. Perform the cut.

Reduce 1 inch (centi) from a 12 inch (cm) length PVC pipe and mark it with a marker.

3. Draw a strip with a pen on the tube with equal spacing of 1?4 inches (cm) of drilling line. Use a tape measure to measure the hole to ensure uniformity and ensure the continuity of the line.

4. Now put the pipe at 1 4, or 90 degrees, and draw a drilling line. Use the same technique as before.

5. Make a borehole for 3?16 inch (cm) drill bits. Drill from the first surface to the other so you can see the straight throughout.

By the time you're done, you should have four rows of parallel drilling. You can use a hand drill, but a drilling press is preferable. With a drill bit of the appropriate size for the shell, the hole should be smaller than the shell.

Please use a regular manufacturer to make sure your drill bit is the correct size for the cover loss.

6. Make the inner and outer ports of the sandy silencer, and the inside is a 2-inch (cm) PVC pipe. Use a rotary tool or sandpaper to remove any blemishes. Make a lid.

You can use a piece of wood for the lid. If not, you can use thick cardboard or other sturdy materials. Round wood or cardboard 2 inch (cm) PVC pipe will do.

7. The pipe can be put into a larger pipe. It should be possible to pass directly through the 2 inch (cm) PVC pipe to the other side. Safely place the back cover on the pipe mouth, it should also be on the PVC pipe, they should fit tightly in place.

8. Fill the back cover with glue. Make sure the glue dries before touching the back cover again. The tubing should be two inches longer than the 2-inch (cm) PVC pipe local, and the lid should be on the other side.

9. In the space in the middle of the pipe and 2 inches (cm) PVC pipe, put steel wool, cotton ball fixation, heating and insulation, or foam mattress. This will ensure that the two main parts of both tubes are strong.

10. Add the other end cap. Hold it in place with glue.

11. Place the silencer on the muzzle of the paintball gun. It's clever enough to fit and neatly contain your paintball gun.
