The working principle of solid vacuum pump is mainly powered by compressed air, using vacuum suction loading and pneumatic positive pressure to convey materials. Crown's solid vacuum pumps are powered entirely by compressed air and are capable of conveying solid particles, powdered materials, slurries, highly concentrated sludge, oil-containing sludge, mineral slurries, and other bulk materials, etc.

The working principle of solid vacuum pump can be divided into the following steps:

Suction process: In the suction process, the volume inside the pump chamber increases, forming a low-pressure area, making the external solid material is sucked into the pump chamber.
Compression process: as the pump chamber volume decreases, the material is compressed, the pressure gradually increases.
Exhaust process: when the pressure in the pump chamber reaches a certain level, the material is discharged out of the pump through the exhaust port, completing a working cycle.

The main application areas of solid vacuum pumps include:

Conveying solid particles and powder materials: it is suitable for conveying all kinds of solid particles and powder materials, such as mineral slurry and high concentration sludge.
Environmental protection field: in sewage treatment and sludge treatment, solid vacuum pumps can effectively transport oily sludge and other bulk materials.
Industrial production: in the production process of chemical, food, pharmaceutical and other industries, solid vacuum pumps are used for material conveying and loading to improve production efficiency

Food grade centrifuge GNLW364GT-FHD is an advanced equipment designed for food and pharmaceutical industries with high standards of hygiene requirements. Its design features and configuration fully reflect the modern industrial manufacturing concepts of safety, hygiene, high efficiency and automation.

1. Polishing of the inner surface of the drum and the drum: this treatment process greatly reduces the residue of the material during the centrifugation process, helps to avoid cross-contamination and ensures the purity and safety of the product. The polished surfaces are smoother and easier to clean, meeting the stringent requirements of food-grade equipment.

2. Temperature and vibration sensors: The equipment's built-in temperature and vibration sensors enable real-time monitoring of key parameters during the centrifugation process. Temperature monitoring helps prevent overheating from damaging the material or the machine itself, while vibration monitoring can detect and prevent potential operational failures, ensuring stable equipment operation and improving productivity and product quality.

3. Automatic Lubrication System: This system automatically provides the right amount of lubricant to key components, reducing wear and prolonging equipment life. At the same time, the automated operation also reduces manual intervention and improves production safety and efficiency.

4. Stainless steel control cabinet: The control cabinet made of stainless steel has good corrosion resistance and easy cleaning, which is able to resist the erosion of chemicals commonly found in food processing environments, and ensure the long-term stable operation of the control system.

5. VFD (Variable Frequency Drive) and PLC (Programmable Logic Controller) overload protection: The VFD enables precise control of the motor speed, improving energy efficiency and reducing energy consumption, while the PLC is responsible for the logical control of the entire centrifugal process, including safety functions such as overload protection. This combination not only improves the intelligent level of the equipment, but also enhances the safety and reliability of the equipment.

6. Hydraulic system is selected from the internationally renowned Swiss brand Viscotherm: Viscotherm, as a famous brand of hydraulic system, is famous for its high quality, high stability and long life. The selection of this brand of hydraulic system ensures the stability and reliability of the centrifuge under high-pressure, high-speed operation, and further improves the overall performance of the equipment.
