According to relevant reports from the Asian Fluid Network, China has completed the solicitation of opinions on the drainage pump, inlet valve, and wash pump industry standards.
"Washing Machine Drainage Pump Technical Requirements" is mainly used to specify the performance of the drainage pump for washing machines and dishwashers. It specifies the standards for drainage pump flow, lift, efficiency, durability, noise and vibration resistance. Flow refers to the amount of water drained by the drainage pump per minute; head refers to the distance and height of the water flow when the drainage pump drains water. The head of the dishwasher is generally between 1.2 meters and 1.5 meters; efficiency means that the drainage pump consumes electricity once to remove the consumption and friction. The power generated by the loss; the noise requirement is no more than 40 decibels.
"Technical Requirements for Washing Machine Inlet Valves" regulates the flow rate, water pressure resistance, high and low temperature, vibration resistance, durability, and noise of the inlet valves for washing machines and dishwashers. The standard of the inlet valve is mainly reflected in the flow of influent water, such as the wide hydraulic washing machine sold in home appliances to rural areas, in order to ensure that the water inflow is smooth even when the water pressure is unstable, especially when the water pressure is low.
"Diesel Washing Pump Technical Requirements" is similar to the washing machine drainage pump, mainly assess the flow, head, efficiency, durability, high and low temperature, noise and other properties. The technical requirements for the dishwasher wash pump are particularly focused on the numerical requirements for the safety load, and the general requirements for durability are up to 5000 hours.
The regulations will be completed in mid-December this year to complete the review of the approval of the Ministry of Industry and Information Technology, is expected to be implemented by the end of next year. After the discussion, the assessment of the performance of the three standard technologies was more complete. The industry standards stipulated the performance of the drainage pump, inlet valve and washing pump flow, high and low pressure, high and low temperature, and durability. Among them, "Technical Requirements for Washing Machine Drainage Pumps" and "Technical Requirements for Washing Machine Inlet Valves" also include dishwasher drainage pumps and inlet valves in the scope of technical requirements.
