DN300 explosion-proof (based on actual reports) star shaped unloader

The company adheres to the service concept of integrity and focuses on the production of DN300 explosion-proof (based on actual reports) star shaped unloaders

Working principle: It is mainly used to install the discharge port of the unloader that works under negative pressure. The upper part receives the material discharged by the unloader and relies on the rotating impeller to transport the material. At the same time, it plays a sealing role to prevent air from being sucked in from the discharge port during pneumatic conveying, protecting the normal discharge of the unloader. If the material in the feeding bin falls by its own weight and fills the gaps between the blades, and is unloaded at the lower part as the blades rotate, it can be discharged continuously in a quantitative manner.

Good sales, structural composition

Rotor impeller: It has several blades and is a key component for material conveying and unloading. The impeller size of 300 * 300 is suitable for the corresponding inlet and outlet sizes, ensuring smooth material conveying.

Shell: Generally, corrosion-resistant (based on actual reports) metal materials such as 304 stainless steel are used to provide support and sealed space for the equipment, protecting internal components from external environmental influences.

3. Seals: prevent dust leakage and material contamination, protect material safety, and maintain a clean working environment. Most materials used are wear-resistant (based on actual reports) and aging resistant rubber.

4. Reducer: Cycloid pinwheel reducer is generally used, which has the advantages of large transmission ratio, good efficiency, and stable operation. It can reduce the high-speed rotation of the motor to an appropriate speed to meet the working requirements of the unloader.

Motor: Choose a one-to-one explosion-proof (based on actual reports) (based on actual reports) motor, strictly design and manufacture according to national explosion-proof (based on actual reports) (based on actual reports) standards, such as YA. and YB series explosion-proof (based on actual reports) (based on actual reports) motors, with optional voltage of 380V and safety protection for use in flammable and explosive environments at 415V.

2、 Characteristics

1. Excellent explosion-proof (based on actual reports) performance: equipped with explosion-proof (based on actual reports) motors, using special design structures such as pure aluminum rotors and aluminum impellers that are not prone to spark discharge, to avoid dust accumulation inside the equipment and reduce risks.

2. Good sealing performance: Multiple sealing measures enhance the overall sealing performance of the box, which can prevent dust leakage and material pollution, protect the safety of materials and the cleanliness of the working environment.

Stable and excellent operation: compact structure, beautiful appearance, bearings and gearboxes are located at a certain distance from the shell, with significant changes in high temperature and lubrication, stable operation, low noise, long service life, and low failure rate.

4. High conveying efficiency: The excellent star shaped blade design ensures smooth material flow and suitable unloading, greatly improving work efficiency. The large diameter design protects a large amount of materials and is suitable for production lines.

Wide applicability: Suitable for powder and granular materials, widely used in industries such as dust removal, metallurgy, chemical, steel, power, grain, food, etc., and can work in positive and negative pressure conveying systems.

Thirdly, use and maintenance

1. Pre use inspection: Check the quantity and type of lubricating oil in the reducer, update the oil after one month of operation, and then replace it once a year; Open the chain shell and check the tension of the chain; Confirm that the rotation direction of the rotor is clockwise (when viewed from the shaft end extending from the reducer, it is consistent with the arrow on the chain housing); Check if the air source interface is blocked by foreign objects and confirm that the interface is clean.

2. Attention during use: Adjust the pressure reducing valve to make the pressure at the sealing part 0.05MPa higher than the pressure of the material inside the valve body, and use oil-free dry compressed air as the gas; During operation, avoid overloading the equipment due to large material particles and strong adhesion, or damage to the equipment or motor caused by legacy and trade foreign objects in the dust collector.

3. Regular maintenance: The transmission and bearing components should be replenished or replaced with grease within 6-10 months after being put into use. If the ambient temperature is high, humidity is high, or there is too much dust in the air, the oil change time should be appropriately shortened; If the equipment leaks air or dust along the axial direction, the pressure cover can be firmly secured.

Our company has always adhered to the service concept of "win-win+efficiency+sincerity", and attaches great importance to customer procurement and various issues in the use of DN300 explosion-proof (based on actual reports) star shaped unloader products in the later stage. We hope to cooperate with you for the sake of service.
