Analysis of the Advantages of Rotary Paddle Level Switches in Sand Making Machines

In sand production, accurate level monitoring is critical to ensuring the smooth operation of equipment. However, due to the harsh working environment and high dust content in sand-making machines, many domestic rotary paddle level switches often experience malfunctions. Sand and dust can penetrate the internal components, leading to accelerated wear of the bearings and mechanisms, resulting in instrument failure or shortened lifespan. This article provides a professional analysis of the unique design and technical advantages of the Jiwei Spin-11 Rotary Paddle Level Switch in addressing these challenges.

Challenges in the Sand-Making Environment

The working environment of sand-making machines is extremely harsh, with frequent impacts from sand and dust particles, which can cause the following issues for level switches:

Dust Infiltration:
Due to the small particle size and large quantity of dust, it easily enters the internal components, damaging critical parts such as bearings and mechanisms, which in turn affects the reliability and stability of the rotary paddle level switch.

High Wear:
In the sand-making process, the coarse and hard particles of the material expose the equipment to a high-wear environment. Over time, this wear can lead to switch failure, reducing production efficiency.

Frequent Malfunctions:
In practice, many domestic rotary paddle level switches lack specialized protective designs, leading to frequent failures when exposed to high-dust environments. This results in frequent shutdowns and increased maintenance costs.

Technical Advantages of the Spin-11 Rotary Paddle Level Switch

To address these issues, the Jiwei Spin-11 Rotary Paddle Level Switch features several design optimizations and technical enhancements that significantly improve its reliability and lifespan:

1. Efficient Sealing Design： The Spin-11 adopts an advanced sealing design that effectively prevents sand, dust, and other fine particles from entering the device. This sealing protection not only prevents dust infiltration but also ensures the device operates normally in high-dust environments. The sealing structure provides dual protection for key components such as the bearings and mechanism, enabling the device to maintain stable performance even when exposed to dust over long periods. This optimized design significantly reduces internal wear caused by foreign particles, extending the maintenance intervals and service life of the device.

2. Application of Wear-Resistant Materials： To cope with the high-wear environment in sand-making machines, the Spin-11 uses highly wear-resistant materials for key components. These materials offer excellent resistance to wear, ensuring stable operation even when frequently exposed to hard, abrasive sand and stone materials. The use of wear-resistant materials not only enhances the device’s impact resistance but also effectively reduces mechanical wear caused by prolonged friction. In continuous operation scenarios, such as in sand-making applications, this design lowers the frequency of maintenance and reduces the total cost of ownership (TCO) of the equipment.

3. Dual Explosion-Proof Certification：The Spin-11 rotary paddle level switch has obtained dual explosion-proof certification for both gas and dust, ensuring its safe and reliable operation in complex and hazardous working environments. This certification not only enhances the safety of the device but also expands its application range, making it effective in high-risk locations such as sand-making machines, chemical plants, and mines. The dual explosion-proof design effectively prevents accidents caused by potentially explosive gases and dust, safeguarding both personnel and equipment. Additionally, this design enhances the durability and stability of the device, ensuring efficient material monitoring even under extreme conditions, thereby reducing the risk of downtime and maintenance costs. As a result, the Spin-11 is an ideal choice that balances safety and reliability.

Conclusion

When faced with the harsh conditions of sand-making machines, the Jiwei Spin-11 Rotary Paddle Level Switch excels with its advanced sealing structure, wear-resistant materials, and non-contact bearing design. These features significantly improve its performance in dusty and high-wear environments. Compared to traditional domestic rotary paddle level switches, the Spin-11 offers greater resistance to malfunctions and a longer lifespan, thereby reducing maintenance costs and improving equipment reliability and production efficiency.

With targeted design improvements, the Spin-11 not only solves issues related to dust infiltration and wear but also provides a stable and efficient solution for material level monitoring in sand production, making it an indispensable piece of equipment for level monitoring in sand-making machines.
