The draft specifies minimum energy efficiency levels and maximum energy consumption levels and qualified inspection methods for household water pumps and electric pumps (using single-phase squirrel-cage induction motors). Public information labeling requirements are also specified. This official draft standard applies to domestic water pumps sold in Mexico with a rated power of 0.187 kW to 0.746 kW and electric pumps using single-phase squirrel cage induction motors. The following types of pumps and pumps are excluded from the scope of this standard: (a) Decorative fountain pumps; (b) Fire pumps; (c) Water massage pumps; (d) Jet (injection) pumps; (e) Multistage pumps (f) Solids treatment pumps (surface or diving); (g) Spray pumps; (h) Bilge pumps; (i) Swimming pool pumps.
The Cnc Cutting Machine has the characteristics of fast cutting speed and small slit in the cutting process, which may lead to limited actual cutting speed, excessive kerf and uneven cutting surface, and eliminate the mechanical failure of the plasma CNC Cutting Machine. Failure to properly set the plasma CNC cutter related parameters during operation will also affect the actual cutting effect.
The hub processing parts of large ships are concentrated in the base of high-power diesel engine, frame, cylinder block, cylinder head, piston rod, crosshead, connecting rod, crankshaft, and gearbox drive shaft, rudder shaft and propeller, etc. The material is special alloy steel, which is generally processed in small batches and requires a processing yield of 100%. The hinged parts have the characteristics of large weight, complicated shape, high precision and large processing difficulty. Large-scale ship pivot processing requires high-power, high-reliability and multi-axis heavy-duty, ultra-heavy CNC cutting machines.
