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.
Mini Fiber Laser Cutting Machine
The Fiber Laser Cutting Machine is a full-enclosed small fiber laser cutting machine with high precision, suitable for cutting small precision parts. The whole fiber laser cutting machine adopts the new three-dimensional protective cover and the pull-out table to protect the user's body and make the work more efficient and safe. The fiber laser cutting machine can be used in the home, it is the preferred choice for home workers and high-precision device processing.
1. The fiber laser cutting machine adopts all-inclusive design to prevent laser radiation from causing harm to human body. It is safe and environmentally friendly, in line with international safety protection standards. Using large visible laser protection safety window, can better observe the operation of the machine.
2. Machine bed of fiber laser cutting machine is welded with 12-16mm thick carbon structural steel dislocation honeycomb structure, machined after stress relief and annealing, then vibration-aging and natural aging treatment, so that the welding and machining stress can be completely eliminated, to ensure excellent rigidity and high precision of the bed, reducing the machining error caused by the vibration of the bed.
3. Laser protection devices of fiber laser cutting machine are installed on both sides of the door, so that the door in the process of falling, if the human body strayed will immediately stop falling, while the alarm light on, thus solving the safety problem of the user.
4. The working platform combined with pull-out slide and roller is easy to operate, safe and reliable, ergonomic, convenient for feeding, and the cylinder locks the back bed to ensure safe operation and cutting precision of the fiber laser cutting machine.
