Rod lenses are precision optical components designed for a variety of applications, including fiber coupling and laser diode beam shaping. These lenses are cylindrical in shape and are made from high-quality optical glass, ensuring minimal light loss and distortion. Applications of Optical Glass Lenses Fiber Coupling: Zero Working Distance: Rod lenses with a 0 mm working distance are ideal for collimating single and multi-mode optical fibers. The ability to position and glue the lens directly to the emission source ensures optimal alignment and efficient light transmission. Collimation: These lenses are particularly effective for collimating light emitted from optical fibers, ensuring that the light travels in a straight path with minimal divergence.

An optical bandpass filter is used to isolate a band of wavelengths from the total spectrum by providing a band of high transmission and bands of high rejection of spectral energy on both the long and short wavelength sides of the transmission band. Features High selectivity: The 940nm bandpass filter can accurately select and transmit light with a wavelength of 940 nanometers, while effectively blocking light of other wavelengths to ensure the purity of the optical signal. Low insertion loss: Advanced coating technology and material selection make the filter extremely transmittance in the target band, reducing the loss of optical signals during transmission. Excellent environmental stability: The use of high-quality substrates and stable coating processes ensures the stable performance of the product under extreme temperature and humidity conditions and extends its service life.

Corrosion resistant chemical pump for alkali liquid IJ type single stage single suction cantilever chemical centrifugal pump is a new product optimized and designed based on the IH series chemical pump, referring to the latest foreign technology and combining with the actual use of users. Its rated performance and installation size comply with the ISO2858 standard, and its manufacturing technical conditions comply with the ISO5199 standard. It is mainly suitable for the transportation of slurry with a solid content less than 50% and crystal impurities in chemical processes. Compared with IH pumps, the structure of IJ chemical pumps has the following characteristics: 1 - Shortened the cantilever of the impeller and thickened the diameter of the shaft; 2 - Asymmetric cross-section volutes and pump casings without mouth rings; 3 - Three imported bearings are used; 4 - Equipped with a new type of seal similar to foreign advanced double face mechanical seals or packing seals. Due to the above structure, the pump has the following advantages: 1 - It can transport high viscosity or solid containing media, and the efficiency of the pump is higher than that of the IH chemical pump; 2 - The asymmetric cross-section volute reduces the impact loss of fluid and shortens the size of the pump casing; 3 - Increasing the strength of the shaft reduces the deflection of the rotor, resulting in stable operation and long sealing life; 4 - The impeller nut is integrated with the impeller, improving the inlet conditions of the pump and enhancing the anti cavitation performance of the pump; 5 - Advanced shaft seal form ensures better sealing effect and reduces pump leakage; 6 - The clearance of the pump can be adjusted without disassembling the pump casing and impeller, reducing maintenance time and saving maintenance costs. Applicable fields: alkali production, salt chemical industry, petrochemical industry, paper mills, pulp industry, refineries, coal chemical industry, power plants, pharmaceutical industry, sugar industry, steelmaking plant, water treatment coating industry (degreasing, phosphating, electrophoresis and other processes)

X-rings, also known as star rings due to their distinctive X-shaped cross- section, represent a thoughtful upgrade from the traditional O-ring. While both serve the purpose of sealing, the X-ring stands out for its refined design— specifically the four sealing lips and a small lubrication cavity in the center. This unique structure helps reduce both friction and starting resistance, making it ideal for dynamic applications. One of the often-overlooked advantages of X-rings is the positioning of the flash line—it sits in the recessed area of the cross-section, which not only improves the seal but also reduces the chances of leakage. In other words, the X-ring takes everything good about the O-ring and pushes it one step further. A Smarter Choice for Demanding Applications X-rings can be used in a wide variety of environments. To ensure optimal performance, the material must be chosen based on factors like temperature, pressure, and the type of medium involved. It’s not just about choosing a rubber ring—it’s about matching the right material to the job. When setting up a system, engineers should factor in peak and continuous operating temperatures, the frequency of use, and in rotating applications, the heat generated from friction. These considerations will determine the service life and effectiveness of the seal. What Makes X-Rings a Better Performer? Unlike an O-ring, which only has one contact point, the X-ring offers four contact surfaces. This means pressure is distributed more evenly, reducing friction by up to 40% and significantly slowing wear over time. It’s a clear performance boost, especially in systems that cycle frequently. Where Do X-Rings Shine? You’ll find X-rings in some of the most demanding applications: Heavy-duty machinery: hydraulic cylinders in excavators and presses Industrial robotics and turbines: rotating shafts and spindles Aerospace systems: actuators in aircraft landing gear that face sudden pressure changes Automotive transmissions: dual clutch systems that require precise sealing Oil and gas: critical components like blowout preventers in offshore rigs Material Options for Different Needs Different environments demand different materials, and X-rings are available in several: NBR (nitrile rubber): cost-effective, reliable across a wide range of industrial uses (-40°C to +125°C) FKM (fluoroelastomer): excellent resistance to high temperatures and aggressive fluids (-20°C to +250°C) PTFE: ideal for low-friction, high-precision sealing in sensitive equipment Why DEDE’s X-Rings Stand Out As a certified high-tech enterprise recognized for “specialization, refinement, and innovation,” DEDE brings over 30 years of experience in sealing technology.
