The material of the dust-free negative pressure specific gravity machine has many important influences on its performance, as follows:

1. The influence of body frame material:

In terms of strength: If the fuselage frame is made of high-strength steel, such as high-quality metal materials like manganese steel, it can ensure the stability of the entire structure. During the operation of the equipment, it can withstand the impact, vibration, and various external forces of materials, and is not easily deformed or damaged, ensuring long-term stable operation of the equipment. For example, when dealing with large quantities and volumes of materials, a high-strength body frame can ensure the normal operation of the equipment, avoiding the impact of frame deformation on sorting accuracy and efficiency.

In terms of corrosion resistance: For some harsh working environments that may come into contact with moisture, corrosive gases, or liquids, if the frame material of the machine has good corrosion resistance, such as using stainless steel material, it can effectively resist corrosion and extend the service life of the equipment. Otherwise, the body frame is prone to rust and corrosion, which not only affects the appearance of the equipment, but may also lead to a decrease in structural strength, affecting the normal use of the equipment.

2. The influence of screen material:

In terms of screening accuracy: The screen mesh is a key component of the dust-free negative pressure specific gravity machine, and its material is crucial to the screening accuracy. For example, using high hardness and high-precision metal wire mesh, such as stainless steel wire mesh, with uniform mesh size and high precision, can accurately separate materials of different densities and improve sorting accuracy. If the precision of the screen material is not high and the mesh size is uneven, it may cause some materials that should have been separated to be unable to be effectively separated, affecting the sorting effect.

In terms of wear resistance: Due to the continuous movement and friction of materials on the sieve, the sieve needs to have good wear resistance. High quality wear-resistant materials, such as special alloy steel or specially treated metal materials, can withstand long-term friction without being easily worn or deformed, ensuring the service life and screening effect of the screen mesh. Otherwise, the screen mesh is prone to wear and tear, causing material leakage and affecting the accuracy of sorting. At the same time, frequent replacement of the screen mesh is also required, increasing the maintenance cost of the equipment.

In terms of electrostatic characteristics: For some materials that are prone to static electricity, the electrostatic characteristics of the mesh material can also affect equipment performance. If the screen material has good anti-static performance, it can reduce the static adsorption of materials on the screen, allowing materials to pass through the screen smoothly and improve screening efficiency. On the contrary, materials are prone to adsorb onto the sieve, causing blockage and affecting the normal operation of the equipment.

3. The influence of fan material:

In terms of wind power output, the material of the wind turbine directly affects the stability and strength of its wind power output. The fan impeller made of high-quality alloy materials or engineering plastics has good mechanical and aerodynamic properties, and can generate stable and strong wind force during high-speed rotation, ensuring good fluidization of materials inside the equipment and achieving specific gravity separation. If the material of the fan is poor, the impeller is prone to deformation and wear, resulting in unstable wind output and affecting the sorting effect.

In terms of noise: good fan materials can also reduce the noise during equipment operation. For example, some fans that use special noise reducing materials or structural designs can effectively reduce vibration and noise during fan operation, providing a relatively quiet working environment for operators.

4. The influence of sealing material:

In terms of sealing performance, the material of the seal determines the sealing performance of the equipment. High quality elastic sealing materials such as rubber and silicone have good elasticity and sealing properties, which can effectively prevent air leakage inside the equipment and ensure that the equipment works normally under negative pressure. If the sealing material is not good, it is easy to age, harden or deform, resulting in poor sealing and affecting the negative pressure effect of the equipment, which in turn affects the specific gravity separation effect of the material.

In terms of temperature resistance: For dust-free negative pressure specific gravity machines working in some high-temperature environments, the sealing material needs to have good temperature resistance. Otherwise, the sealing components are prone to softening and failure at high temperatures, leading to equipment leakage and affecting the normal operation of the equipment.
