Non-clogging pump design requirements

With the development of science and technology, the application area of ​​pumping solid substances is expanding, such as sewage sludge, mud pulp, ash residue, grain starch, beet fruit, shellfish and so on. There are two main requirements for pumps that deliver these substances: First, there is no blockage and second, wear resistance. The main wear-resistant and material-related, non-clogging depends mainly on the structure of the impeller. Currently as the main structure of non-clogging pump impeller are: 1. Open or semi-open impeller; 2. Swirl impeller; 3. Single (dual) flow impeller; 4. Spiral centrifugal impeller.

Led Waterproof Flood Light

The material of the led waterproof flood light body is the surface treatment of aluminum alloy die-casting and electrostatic spraying. The coating is resistant to high temperature, acid and alkali, and anti-aging. The waterproof outdoor flood lights body adopts the integrated design of light source and electrical appliances, with a compact structure and small volume. The reflective surface is designed to form light distribution for various needs, with high luminous efficiency and small glare light source.

According to customer needs, single-ended or double-ended metal halide lamps or high-pressure sodium lamps can be used. The led flood outdoor lighting head adopts tempered glass, which is safe, resistant to high temperature and high Good strength and light transmission The sealing strip is an anti-corrosion silicone rubber seal, which has good sealing performance, waterproof and dustproof applications. High performance magnetic ballasts, triggers and capacitors are suitable for signs, stadiums, squares, trees, billboards, parking lots Fields, building exterior walls, etc.
