Select the appropriate submersible pump must be selected from four aspects: 1, liquid delivery; 2, the device head; 3, the nature of the liquid; 4, the pipeline layout and operating conditions and so on. So what happens when we can not choose submersible pump? 1, Metering requirement 2, High head lift 3, Low lift and large flow rate 4, Medium viscosity (more than 650 ~ 1000mm2 / s) 5, Medium gas content 75%, Flow rate smaller and viscosity less than 37.4mm2 / s 6, on the occasion of frequent or inconvenient to pump If there is more than the above conditions we do not choose submersible pump!
These beads are coated with a special coating materials, during the manufacture of the glass beads, which will improve the characteristics of moisture-proof and adhesion of glass bead. In the way, the life cycle of the glass beads can be prolonged and this enhances the beads reflectivity in a rainy night. These beads are usually used in white or yellow line-construction of highway.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
