Diaphragm pump flow adjustment is based on the rotation adjustment mechanism to adjust the piston stroke to adjust. The principle is: rotation adjustment mechanism handwheel (you can see the position of the dial on the change), through the adjustable shaft and slide shaft axial transformation, the movement through the slide shaft on the chute into the eccentric radial Displacement, through the connecting rod to promote the piston, due to changes in piston stroke, so as to achieve the purpose of flow control.
Diaphragm pump maintenance and other types of pumps are different, the main points are as follows:
1, check the valve should pay attention to aging deformation of the seal ring, the spring is to reduce the seriousness of the spring, the valve port and the valve there is no wear, corrosion and other defects, the valve should be installed with the pump body flange surface level, can not be recessed;
2, the diaphragm replacement, disassembly pump head should be lifted in advance to prevent the fall damage;
3, the adjustment mechanism disassembly to calibrate the length of the stroke position (stroke length of 5mm), remove the scale seat, slide the scale ring into the calibration position, the measured stroke length should be exactly the same scale;
4, when the piston is disassembled, use a special pointed tool to remove the packing ring from its slot, taking care not to damage the ring slot;
5, Worm wheel to be checked, the teeth should be intact, there should be no cracks or broken teeth, the installation to check the engagement conditions.
Corrosion resistant Soluble PTFE
Corrosion resistant soluble PTFE, also known as polytetrafluoroethylene, is a type of polymer that possesses excellent resistance to corrosion and chemical attack. It is a hydrophobic material, meaning it repels water and other liquids, making it highly suitable for applications where corrosion protection is crucial.
Soluble PTFE is a unique form of PTFE that can be dissolved in certain solvents, such as hydrocarbons, to form a liquid solution. This characteristic allows for easier application and coating on various surfaces, including metals, plastics, and ceramics.
The corrosion resistance of soluble PTFE is attributed to its strong chemical bond structure, which prevents the penetration of corrosive agents. It can withstand a wide range of harsh chemicals, including acids, alkalis, solvents, and oxidizing agents, making it ideal for use in industries such as chemical processing, oil and gas, automotive, and electronics.
In addition to its corrosion resistance, soluble PTFE also offers other beneficial properties. It has a low coefficient of friction, which reduces wear and tear on surfaces, and it has excellent electrical insulation properties, making it suitable for electrical components and wiring.
The application of soluble PTFE can be done through various methods, such as spraying, dipping, brushing, or roll-coating. Once applied, it can be cured at elevated temperatures to form a durable and protective coating. The thickness of the coating can be adjusted to meet specific requirements, providing flexibility in application.
Overall, corrosion resistant soluble PTFE is a versatile material that offers exceptional protection against corrosion and chemical attack. Its unique solubility feature allows for easy application on different surfaces, making it a valuable solution in various industries where corrosion protection is vital.
