The problems of energy supply systems and sanitation

In the total energy consumption in water supply and sanitation in human settlements and industrial facilities for more than 90% are pumping systems for natural, potable, industrial and waste water to supply reagents and air. Due to rapidly rising prices for gas and oil in all countries urgently raises questions of energy efficiency of water supply and sanitation, as well as their elements.


This explains the stringent requirements of international and European standards (ISO and EN) as to efficiency and quality of pumping equipment. Thus, the international association of European manufacturers of pumps Grundfos up15-29su introduced a new labeling scheme approved pumps. Underlying the need for such labeling lay the fact that there are large differences in energy consumption and different levels of technological development in the East and West Europe. Only 20% established in the European Union, pumping systems have been optimized for power consumption [1].

The scheme of energy labels is focused on the potential energy savings associated with a growing international scientific and technological progress. This scheme is described in the voluntary agreement, entitled "Industrial undertaking", promulgated by the Europump. Currently, this agreement was signed by four European manufacturer of pumps, the leading positions among which belongs to the concern Grundfos. These industrial obligations include a unified classification scheme based on energy efficiency index (EEI - Energy Efficiency Index), formed on the basis of the annual load profile and distributed systems with almost the same load profile. The average pump is placed in category D and E.

Signing of an agreement on energy labeling pump manufacturers undertake to mark all future pumps Acting as the territories of Canada and most countries of the CIS Building Regulations (SNIP), standards, specifications and other normative and technical documents for design and construction of the former Taco 007 IFC Canada do not meet modern requirements and conditions. They require a fundamental change certain provisions and to make new demands.

In particular, the current GOST 10428-89. "Little Giant 6-CIA pump units for Circulating borehole for water. The basic parameters and dimensions" is outdated in terms of basic parameters and dimensions for the Taco 007 boreholes, where the best foreign models outperform the multiple indicators.

For example, in Table 4. GOST 10428-89 is specified pumping unit Little Giant 4 with a capacity Q = 6,5 m3 / h with a head of H = 4 bar, efficiency = 38%, diameter of 95mm aggregate. With the same parameters of Q and H SQE pump has a diameter of 74 mm and an efficiency of 44%. Similar comparisons can be reduced and other pumping units. The manual for SNIP 2.04.02-84 design automation and control systems, water supply indicated contrary to the fundamental principle of saving any Taco 007-F5, install a good pump to your piping system, which "usually an automatic control system with adjustable drive advisable to use a pumping plant is relatively high power (75-100 kW and above ). " At the same time, all the pump manufacturers provide integrated automation systems for all types and sizes of pumping equipment.
