External Cylindrical grinding, cylindrical grinding is mainly carried out on an external cylindrical grinding machine, which is used to grind the outer cylinder, outer cone and shoulder end surface of shaft-type workpieces. During grinding, the workpiece rotates at a low speed. If the workpiece reciprocates in the longitudinal direction at the same time and the single-stroke or double-stroke movement in the longitudinal direction moves the grinding wheel relative to the workpiece, it is called longitudinal grinding.

During grinding, the workpiece rotates at a low speed. If the workpiece reciprocates in the longitudinal direction at the same time and the single-stroke or double-stroke movement in the longitudinal direction moves the grinding wheel relative to the workpiece, it is called longitudinal grinding. If the width of the grinding wheel is greater than the length of the surface to be ground, the workpiece does not move longitudinally during the grinding process, but the grinding wheel continuously feeds the workpiece continuously, called the plunge grinding method. The efficiency of the plunge-cut grinding method is generally higher than that of the longitudinal grinding method. If the grinding wheel is trimmed into a forming surface, the plunge grinding method can be used to process the formed outer surface.

This pump is designed to enhance the water pressure in residential settings. It uses a PC chip to control the electric pressure switch, which helps prevent frequent switching and extends the life of the pump.
To avoid the pump getting stuck when not used for long periods, it will automatically start every 72 hours for 10 seconds.
If the inlet lacks water, the pump will continuously detect for 8 minutes and activate the water shortage protection system automatically to prevent damage from dry running.
The pump also features a start-up delay function, ensuring it starts after 3 seconds when power is turned on, reducing electrical sparks and enhancing safety.
Equipped with a flow sensor, the pump ensures stable pressure without affecting the water flow.
