ã€Asia Pump Network News】 Fluorine plastic magnetic pump in recent years, an important breakthrough in magnetic pump research and development. Fluorine plastic magnetic pump using magnetic coupling transmission power, completely sealed without leakage, when the motor drives the magnetic coupling of the outer magnet rotation, the magnetic field lines through the gap and the isolation sleeve, acting on the magnet, the pump rotor and motor synchronization Rotation, no mechanical contact to transmit torque. Because the liquid is enclosed in the isolation sleeve, the leakage of the material is completely solved, the pollution is reduced, the energy is saved, the environment is purified, and the physical and mental health of the staff in the production line is protected. Combined with many domestic units of the media and the domestic production of fluorine-lined magnetic pump process conditions. The following small to introduce the characteristics of fluorine plastic magnetic pump. Fluoroplastic magnetic pump features Product Features 1. Pump lining, impeller rotor, isolation sets are made of pure F46 material from a one-time molded, no impurity precipitation, very suitable for conveying high purity, highly corrosive chemical liquids ; 2. Pump body shell with ductile iron, the pump body designed according to the national standard flange, mechanical strength is very good, and can withstand heavy pipe load; 3. Flow components lined with F46 material, with six smooth, superior hydraulic performance, Hydraulic friction loss is small, high efficiency features; 4. Shaft, bearing sleeve, static and dynamic ring are made of non-pressure sintered silicon carbide, with high hardness, high wear resistance, high corrosion resistance and
Other characteristics; Spiral groove design, make the sliding bearing auxiliary lubrication more convenient and easier to remove the heat generated by the friction generated by the pump running; 6. Isolation sleeve outside the addition of imported materials made of PPS special reinforcement cover, so that the pump can withstand higher Of the system pressure, and can eliminate the use of metal sleeve due to magnetic vortex generated heat; 7. Inner and outer magnetic selection of NdFeB material, the magnet surface up to 3600 Gauss, the successful move Of the torque transmitted to the impeller, and in the case of large flow will not slippery, but also to prevent the impeller impeller contact with the back of the ring, so as to prevent friction and heat to melt fluoroplastic parts to ensure that the magnetic pump in the highly corrosive Occasions to normal operation; 8. The entire pump group with a pull-type structure, a person can carry out internal maintenance and parts replacement, and do not need to disassemble the pipe.

Cross Recessed Screws
Application scope: mostly used for the connection of smaller parts.
It has pan head Screws, countersunk head screws, half countersunk head screws and large flat head screws. Pan head screws and large flat head screws are used in the occasion where the nail head is allowed to be exposed;
Half countersunk head screws have an arc-shaped head, and its top is slightly exposed after installation, and beautiful and smooth, generally used in instruments or precision machinery; countersunk head screws are used in places where the nail head is not allowed to be exposed.
