Explosion-proof vibration motors should generally be cleaned and refueled after 2,000 hours of use. There are two ways to clean bearings:
1. Hot oil cleaning method
Due to long-term use, bearings hardened by soft dry oil or anti-rust paste should be immersed in thermal engine oil at 100-200°C, clamp the bearing with pliers, and use a brush to clean the oil stains on the bearing. Soft dry oil or anti-rust paste melts when heated to 100-200°C and is easily washed out from the gaps in the bearing. Sometimes it is just a matter of shaking the bearing in oil several times. Oil dirt will also flow away from the gaps.
When cleaning the radial spherical bearings of old motors or imported motors, the balls, ball frames, and inner rings should be turned laterally out of the outer ring and then immersed in hot oil. When cleaning short cylindrical roller bearings, the rollers should also be cleaned. , the bead frame, inner ring and outer ring are detached. During hot oil cleaning, the oil temperature should not exceed 20°C.
2. General cleaning method
Soak the bearing in kerosene for 5-10 minutes, hold the inner ring with one hand, and rotate the outer ring with the other hand. The dry oil or anti-rust paste on the bearing will fall off. Then put the bearing into cleaner kerosene, scrub with a soft brush to clean the oil in the balls and gaps, then put it into gasoline to clean it once, take it out and put it on clean paper. When cleaning radial spherical ball bearings and short cylindrical roller bearings, the balls, ball frames, inner rings and outer rings should be separated and cleaned.
The bearings installed on the shaft are mainly cleaned by spraying oil or spraying with an oil gun. The oil stains that are easy to be cleaned are first washed with kerosene and then gasoline; the oil stains that are difficult to be cleaned are first rinsed with 100-200°C hot engine oil. Or spray with an oil gun, and then clean with gasoline. Be careful not to use sharp tools to scrape hardened grease or rust on the bearings to avoid damaging the smoothness of the bearing rolling elements and groove rings. Clean the explosion-proof vibration motor bearings and wipe them dry with a clean cloth.

Compared to ordinary suction machines, the suction efficiency is high and efficient.
The pneumatic grain suction machine has a complete fan and frequency conversion control system, and adopts advanced multi-channel air source control system and automatic adjustment device. The fan air volume can be adjusted arbitrarily; The use of negative pressure fans converts excess air pressure into power, greatly improving the suction rate. Imported fans and dedicated reducers are selected for the fan. It can meet the needs of industrial production, enterprise operation, and the civilian market for wind power generation.
2. It has the characteristics of large capacity, low power consumption, high energy consumption, and convenient maintenance.
This machine has a compact structure, smooth operation, convenient maintenance, and can be equipped with a dust recovery device. At the same time, the compressed air flow rate used in this machine is much larger than that of traditional grain suction devices. Its power consumption is only half that of traditional grain suction devices, and under the same material conditions, this machine consumes much less electricity and energy compared to ordinary grain suction machines.
3. High degree of automation, capable of remote operation and continuous automated operation, safe and reliable.
Pneumatic grain suction machines are widely used in our daily lives, especially as small suction equipment in the grain industry. So how should pneumatic grain suction machines be used? I believe many friends don't know much about this, but actually using such a device can also save a lot of costs. Due to its excellent environmental performance, it has minimal impact on the environment during use. For production enterprises, it can save energy costs, while for consumers, it can also save financial expenses. Of course, this requires the equipment user to have a good understanding and understanding ability.

The hose grain suction machine is a device used to absorb granular materials. It sucks the material into the machine through the hose, and then separates the material through the separation process inside the machine. Compared with traditional feeding methods, hose grain suction machines have many advantages and disadvantages, which we will introduce in detail below.
advantage:

1. Efficient: The hose grain suction machine can efficiently complete the suction work of granular materials, and its working efficiency is much higher than the traditional feeding method.
2. High flexibility: The length of the hose of the hose grain suction machine can be adjusted freely according to needs, and it can work in various complex sites and is more flexible than the traditional mechanical feeding method.
3. Transportable: The hose grain suction machine is small in size and light in weight, and can be easily moved to the required location for work.
4. No rust: The hose grain suction machine is mainly made of stainless steel, and there will be no problems such as rust when handling corrosive substances.

5. Simple operation: Hose grain suction machines are generally equipped with automatic control systems, which are simple and convenient to operate and can be used without special training.

1. The processed material should not be too large or too hard;
2. The material is dried and roasted before crushing, the effect is better;
3. It is necessary to select the appropriate screen according to the needs and the oil content of the material;
4. After crushing, the crushing chamber needs to be cleaned;
5. The machine should be placed stably in a ventilated and dry place;
6. A thermal relay is installed inside the machine to protect the motor. When the machine is overloaded during operation, it will automatically stop. If the red light is not on after shutdown, the fuse FUSEE has been blown out and must be replaced. After cutting off the power supply, clean up the crushing chamber, and when the thermal relay returns to normal (it takes about 5 minutes), the power supply can be turned on again to start working.

How to use:
1. The Grease grinder is randomly equipped with 3 kinds of screens with different fineness. According to the crushing requirements of customers and the properties of materials, it is necessary to select a suitable screen and put it into the crushing chamber. After installing the screen, close the cover tightly, and then turn on the power to After the machine runs for about 1 minute, the material will slowly flow into the crushing chamber for crushing.
2. The hopper should be placed under the machine. If it is not placed properly, the powder will float out and cause waste. The receiving hopper is made of 304 steel plate. If the receiving hopper is deformed during use, it can be corrected by hand or tools.
3. The green button of the machine is the start button, and the red button is the stop button. If you need to stop midway, you need to close the feeding hopper first, and try to make the materials in the crushing chamber crushed before shutting down. If there is an abnormality in the machine, it needs to be shut down immediately, and the machine can be restarted after checking that there is no problem.
4. After the grinding is finished, it is necessary to turn off the machine first, and it is best to unplug the power socket before opening the machine cover to clean the grinding chamber and replace the screen.

Grease grinder use 750W high-speed motor, easier to operate, evenly crushed, very quiet, stable and powerful.
Special cutter design, faster feeding speed, more suitable for materials with high oil content.
Equipped with a pure copper wire motor, the machine works more powerfully and efficiently, and has a longer service life. The copper wire motor has lower noise, less heat generation, and is more energy-saving.
