Solenoid valve installation instructions: 1 before installation should carefully read the product manual, check the product is fully consistent with the requirements of use, familiar with the installation points, be prepared. 2. Check whether the parameters marked on the nameplate are the parameters of the selected product and whether it matches the instruction manual. 3. Before taking over the pipeline with 0.3Mpa pressure flushing, the metal powder in the pipeline, residual seal material, rust and so completely removed. 4. Note the cleanliness of the media, if the media mixed with dust and other impurities impede the normal operation of the solenoid valve, the pipe should be installed filters. 5. Solenoid valve should not be installed in the pipeline depression, as installed in the container discharge pipe, be careful not from the bottom of the container leads, but should be installed in the container slightly above the bottom of the position. 6. If the media will start the phenomenon of water hammer, then you should use multi-function solenoid valve or take appropriate precautions. 7. Steam solenoid valve inlet side should be equipped with a trap, where the takeover should be tilted, traps installed in the low, it is best to install multi-pass recoil filter. 8. Solenoid valve flow direction is generally oriented, can not be installed anti, usually in the body with "arrow" to indicate the flow direction of the medium, when installed in accordance with the "arrow" direction of installation. 9. Solenoid solenoid valve solenoid valve components should be upright, perpendicular to the pipeline, some products have special provisions, please install according to the instructions. . 10. Take care when the seal material can not be used in excess. For threaded connections, the take-over thread should be held within the effective length and chamfered with a file at the half-pitch at the end, beginning at 2 teeth from the end to wind the seal tape, or an excessive amount of seal tape or adhesive will enter the solenoid Valve, and the occurrence of an accident that hinder normal operation. 11. Solenoid valve installation should have some space reserved for its routine maintenance and regular maintenance. 12. Installation with a wrench or pipe clamp to fix the valve body, and then screw on the take over, must not force the coil assembly caused by deformation, the solenoid valve is difficult to work properly. 13. In the pipeline rigidity is not enough, or the phenomenon of water hammer, please valve before and after the takeover with a solid fixed bracket. 14. When using in a freezing place, protect the pipe with insulating material or install a heater on the pipe. 15. Check to see if the solenoid valve itself and its connection to the receiver leak. 16. Connection of the coil leads to check the correct, especially the three leads the occasion. 17. The electrical components connected to the solenoid valve, such as relays, switches and contactors. When opening the valve, the contact should not vibrate, otherwise the work will be unreliable and affect the life of the solenoid valve. 18. Electrical circuit to access the appropriate insurance line, as the electrical circuit protection. 19. In order to facilitate the maintenance and repair operations, or without interruption of continuous production, for the general solenoid valve, it is recommended to use bypass isolation installation method.
Grinding Glass Beads, Resistance thermolastic Glass Beads for Grinding Glass Beads for Grinding,Road Marking,Blasting, Glass Beads ,with the advantages of smooth surface, even size, high hardness, wearable and stable, widely used as disperser, grinding media and filler materials in day, paint, ink and chemical industry etc.
Grinding and Polishing Glass Beads :
Size:0.8-1mm;1.0-1.5mm;1.5-2mm;2.0-2.5mm; 2-3mm;2.5-3mm; 3-4mm; 4-5mm; 5-6mm etc.
The ability to operate a mill with smaller-diameter grinding media greatly increases the mill's efficiency and can overall further increase the quality of product through finer grinding. However, smaller Glass beads are more prone to hydraulic packing due to their decrease in mass per bead. Hydraulic packing occurs when the drag flow from the product pulls the media with the product and ultimately causes media packing around the discharge screen.
Glass beads have replaced the conventional grinding media : Ottawa sand, Steel balls, Pebbles, Ceramic balls etc. in Sand mills, Ball mills, Attrition mills for the following simple reasons :
They do not react or get reacted with the materials that are ground.
Being spheres, every bead in charge takes important part in the grinding operation.
They have smooth glassy surfaces and hence slide without much friction there by reducing the load on the stirring mechanism.
Glass beads are of interest to the following industries:
a) Paints. b) Pigments. c) Ink & Printing Inks. d) Dyes. e) Chemicals. f) Cosmetics.
g) Gums & Waxes.
