What Is a Pneumatic Hammer?

The pneumatic hammer is an impact structure and an advanced powder falling device. The product is new and unique. It is used to prevent the powder from sticking, blocking and bridging in the pipeline, hopper and silo transportation. It uses the aerodynamic principle to adjust the striking force by adjusting the air supply pressure. The outer wall of the device is tapped without deformation. And has explosion-proof function, widely used in chemical, chemical fertilizer, food, ceramics, glass, cement, pharmaceutical, plastic, fuel and other powder processing industries.

When the pneumatic hammer is not in the state of compressed air (more than 3Kg / cm), the magnetic piston is firmly fixed on the substrate by means of strong magnetic force. Tee

Pneumatic hammers in the prior art have a structure in which a hammer head equipped with a magnet is used to attract the substrate, and the hammer head is forced to be opened by a fixed pressure air source, so that the hammer head is knocked out, and then the gas is cut off by a three-way solenoid valve Then, a spring installed under the hammer head is used to reset the hammer head to complete an impact.

The pneumatic hammer of this structure has several defects;

1. Due to repeated impacts of the hammer head, the magnet on the hammer head is easily broken, resulting in weakened pull-in strength.

2. Because the magnet on the hammer head and the substrate are attracted, it is necessary to push the hammer head by a fixed pressure air source, so that the impact force is single and cannot be adjusted, which will cause greater damage to the hit bin. When installing and using, the channel steel must be welded on the silo. Installing the air hammer above the channel steel can eliminate the hidden danger of the silo being damaged.

3. The pneumatic hammer of this structure has a heavy weight because the hammer head is made of steel and is easy to cause fatigue and even fracture of the spring installed under the hammer head. Causes difficulty in resetting.

4. The noise is too loud and there is no dust protection.

The advantage of the pneumatic hammer (2nd generation) is that its striking force is adjusted by adjusting the air supply pressure. If the knocking force is too small to prevent the blockage, the air pressure can be increased. On the contrary, if the knocking force is too large, the pressure will be reduced. If the customer chooses the wrong model, the impact force is too strong or insufficient, and the pressure can also be adjusted to solve the impact of the hammer. This structure that can change the impact force ensures the convenience of air hammer selection. If connected through a relay port, several impact pneumatic hammers can be operated in series and strike simultaneously. It is a clean, pollution-free and low energy consumption ideal cleaning equipment. ^[2]

Pneumatic hammers can be controlled by multiple units at the same time. This function can be achieved by using relay pipes.

1. Relay piping is a piping method that directly connects multiple air hammers.

After the pneumatic hammer is installed, be sure to install a cable to prevent it from falling off, otherwise it may fall and cause injury due to the impact of the impact.

1. When installing the pneumatic hammer, please wear safety helmets, safety shoes, safety belts, and safety equipment.

2. When the board at the installation part is thin, please weld the reinforcement board, otherwise the installation part may be damaged due to impact.

3. If welding the reinforcing plate, please make sure that there is no gap between the reinforcing plate and the hopper, and leave an exhaust port of about 10mm to facilitate the exhaustion of air so that the impact force can be fully transmitted. To avoid damage to the hopper, be sure to weld more layers.

4. In order to prevent falling off, please use a cable to hoist and fix the body, otherwise the bolt may loosen due to the impact and fall off.

5. When fixing the body and flange with bolts, please install spring washers on the top and bottom, and tighten strictly according to the tightening torque and check regularly.

6. Please install an air filter before piping. If garbage or dust is mixed in, it may cause malfunction.

7. Do not exceed the required impact force during use, otherwise it may cause damage to the silo or installation site.

8. For continuous continuous blows, please keep the time setting for more than 1 second. If it is less than 1 second, it may cause malfunction.

9. Please confirm that the striking surface of the mounting flange must be a solid plane. If necessary, weld reinforcement.

10, the installation of the pneumatic hammer in the appropriate position can play its maximum performance.

This pneumatic hammer also has explosion-proof function, and it is also suitable for hazardous places such as chemical industry and mine, etc.
