The bar flow meter is composed of a detection rod and a pressure taking port. It crosses the pipeline to the vertical of the pipe and the central tube axis, and a detection hole is arranged on the detection surface of the detection rod and the back flow surface of the detection rod, respectively. Pressure tube and static pressure pressure tube lead out, according to the total pressure and static pressure differential pressure value, calculate the flow through the pipe.
1, before the installation of Pakistani flowmeter, the pipeline should be cleaned. When the measured media is unclean, add a filter. Otherwise, the turbine and bearing are easily stuck and no flow can be measured.
2. When disassembling the flowmeter, the magnetic induction part cannot collide.
3. Set the meter factor before putting it into operation. Carefully check to make sure that the instrument wiring is correct and the grounding is good before sending power.
4. When installing the bar flow meter , the front and rear pipe flanges should be horizontal, otherwise the pipe stress has a great influence on the flow meter.
5, the flow meter body selection area with 316 stainless steel materials to prevent corrosion, if the explosion-proof zone must also be explosion-proof results.
6, the bearing is generally carbonized tungsten, PTFE, carbon graphite three specifications: tungsten carbide, high precision, it as a standard industrial control; PTFE, carbon graphite can be anti-corrosion, generally in chemical industry places priority. The square of the bearing life flow rate is positive and negative, so the good flow rate is good at 1/3 of the large flow rate.
7. The sensing probe detects the movement of the rotating body and converts it into a pulsed digital electrical signal. Its output voltage of the electromagnetic coil is close to the sinusoidal curve. The frequency range of the pulse signal changes linearly with the measured flow rate. The typical range is 10: 1,25:1 and 100:1 three specifications. The resistance of the solenoid coil is generally less than 2000Ω, which may be damaged if larger than this value.
Polyurethane System For Safety Shoe Sole
High weatherability,excellent hydrolysis resistance,good flexibility at low temperatures,good cold and flexing resistance,high strength and good hand feel,low density and excellent dimensional stability.
Xuchuan Chemical also provides PU system for other various applications such as solid tires, marine fender, shock absorber...Customized products are also available .
A Pu system for shoe soles refers to the use of polyurethane (PU) material in the manufacturing of shoe soles. PU is a versatile and durable material that offers several advantages for shoe soles.
Here are some key features and benefits of using a PU system for shoe soles:
1. Cushioning: PU provides excellent cushioning and shock absorption properties, making it ideal for footwear that requires high levels of comfort and impact protection.
2. Lightweight: PU is a lightweight material, which helps reduce the overall weight of the shoe, making it more comfortable to wear and reducing fatigue during extended use.
3. Flexibility: PU offers good flexibility, allowing the shoe sole to bend and flex with the natural movement of the foot. This enhances comfort and prevents stiffness or discomfort during walking or running.
4. Durability: PU is highly durable and resistant to wear and tear, making it suitable for long-lasting shoe soles. It can withstand repeated use and exposure to various environmental conditions without losing its structural integrity.
5. Slip resistance: PU can be formulated with specific additives to enhance its slip resistance properties, providing better traction and grip on different surfaces. This is especially important for safety footwear or shoes used in slippery conditions.
6. Design versatility: PU can be molded into various shapes and designs, allowing for greater design flexibility and customization options for shoe soles. This enables manufacturers to create unique and visually appealing footwear.
7. Water resistance: PU can be made water-resistant or waterproof, which helps protect the shoe sole and the foot from moisture, rain, or other wet conditions.
Overall, a PU system for shoe soles offers a combination of comfort, durability, flexibility, and design versatility, making it a popular choice for footwear manufacturers and consumers alike.
