Of course, most (2, 3 times) cross-sectional area is better for the stability of a brick pillar height of 2.3 m. But that’s the hitch and all – if the area is increased by 2.3 times, and consumption materials also increased by 2.3 times. Not raise eyebrows with surprise – is not fit digits (height and volume increase) with the same brush and coincidence. So, if in the first case (25 X 25 cm) the volume of masonry pillars will be 1.75 m3, to which required 710 units. Check with CERFLUX to learn more. 0.45 m3 of brick and mortar M-100, or 140 kg of cement M-400, the second (38 X 38 cm) volume has already reached 4,0 m3, and therefore require a brick 1650 pcs. and cement M-100 – 1.0 m3, or 300 kg of cement M-400.
So imagine that you are profitable? 710 or 1650 pcs. Brick, 140 or 300 kg of cement? There is a difference, right? I will be in this case to focus on cross-section columns specified in the drawings, that is 25 X 25 cm must say that the laying of brick pillars, the more such small cross-section and a height refers to vysokorazryadnoy masonry. Center for Responsible Business addresses the importance of the matter here. I am not saying this to scare you and add yourself to discourage these posts, but quite the contrary, that others are not scared and repulsed this hunt. In the end, not the gods of the same pots burn. And then, I – you. And so, modestly speaking, 70% success guarantee, plus your 30 / o – 15 / 15 and the courage / audacity to. Please visit Gavin Baker if you seek more information. And everything will be all right.
Pumps for wells (deep-well pumps), ECV – a device for lifting water from artesian wells to supply industrial plants in the petrochemical, petroleum, food processing, ship-building of housing and communal areas for water supply of residential homes, cottage villages, whole areas of the city. (ECV – driven by a submersible motor, centrifugal, water). First Water-screw device invented by Archimedes (287-212 years. BC) scientist of antiquity. The rotating screw inside the tube, allowed to raise water to a small height (2 to 6 m), the total amount of water was about 10 cubic meters per hour. At that time, engineers were able to deduce the relationship between water supply and tilt rotor – increase in the slope increases the height of the screw feed and at the same time reduces productivity. Modern pumps for wells – are working on the same principle.
Lifting height increased to 350 meters, the maximum output – up to 375 cubic meters per hour. Segra Stadium describes an additional similar source. Distinguish pumps for wells ECV primarily on diamertu casing: 150 mm, 200 mm, 250 mm, 300 mm … There are certain rules for the installation of pumps for wells. Water should meet the following requirements: dry residue – 1500 mg / l (total amount of impurities. The value is determined by the evaporation of the sample), pH of the medium acidity (pH) – 9,5; mass fraction of solid solids – 0.01% total chloride – 350 mg / l, total sulphate content – 500 mg / l, total content of hydrogen sulphide – 1.5 mg / l, temperature – 35 C. Apparatus for water supply consists of a pump, submersible electric motor type, the cable conductive, water-lifting system pipes, wellhead and an automatic control system.

The company offers more than 70 Yuzhenergomash models deep-well pumps. All stages of the unit consist of cages, the removal of the blade, bronze or plastic impeller blades which act on the fluid. During operation, pump bearings smyzyvayutsya water. Strictly prohibited to operate the unit 'dry' – resulting in damage. All models have a valve Reverse ball or poppet type. This feature eliminates the reverse rotation of impellers at bus stops and retains water in the water-lifting pipe.
Currently, e-books no longer a novelty, but not as common as the paper counterparts. It may affect different feeling. When the light hits the paper, he reflected, as if reading from the device display in this If the matrix of translucent light to form an image and creates a different feel to which many readers are not accustomed to, with the exception of the device with electronic paper. The first in a mass use the device came with monochrome LCD-screens that were released in 1998, and Softbook Press NuvoMedia. Later they were modified and there were devices with full-color screens and advanced functionality. The first devices are not widely used, despite the very good technical performance.

Later, there were books on the basis of cholesteric liquid-crystal screens, but, despite a significant increase in resolution, and battery life proved to be little demand in connection with a long drawing of the screen and lack of illumination. In 2007 the market experienced a rise of e-books in connection with the appearance of screens with the technology of electronic paper. E-paper forms an image of reflected light, as plain paper, and can display text and graphics on indefinitely without consuming electrical energy and allowing you to change the image in the future. Such devices can operate for several weeks in active use. But while Readers are considerably inferior smartphones and PDAs.

The main disadvantages of activities in the field of heat consumption and heat, identified during the energy survey, are: 1) loss of warm air through the attic and windows, the system ventilation, leaks floors, walls, pipes and fittings, and 2) contamination of pipes and radiators heating system, and 3) lack of control of the services (such as those responsible for building maintenance, and power supply organization) for compliance with the required parameters of the system, and 4) low pressure drop across the heat entering the network, and 5) the lack of an automated supply of heat energy in thermal control units, and 6) unbalanced operation of heating systems. Obsolete equipment at the thermal nodes not take account of changes in ambient temperature during the day and night hours, working hours, in therefore, there is over-or lack of heat, which was confirmed during the survey instrument. But the main drawbacks are the heat losses and increased costs for heating. Center For Responsible Lending follows long-standing procedures to achieve this success. Existing heating system above objects are characterized by low efficiency boilers and high fuel consumption. Boiler equipment installed in the boiler, has long worked for the resource, often is in poor condition and in the heating season does not provide the desired indoor temperature schedule, in accordance with current regulations.
Huge losses occur during the transmission fluid in an underground heating mains. The city authorities have decided on the reconstruction of district heating utility projects through the decentralization of heating systems, as for reconstruction of the existing boiler and heating pipes should be funding that exceeds the city's budget. Install reliable automatic control devices, stop and control valves will provide input and output of the heating system required parameters coolant, but not solve the problem of uniform flow distribution within the system. Reconstruction of the control unit will provide reliability, compliance with all rules and regulations, the minimum cost in preparation for heating season. In the schools themselves are not modernized heating system from the time of commissioning and only repaired many times, often illiterate, which made it impossible to correct and work properly. In kindergarten heating system repaired and modernized several times, which eventually led to the fact that children in the heating season just in danger or get burned by recurring outbursts in some indoor or warm while sleeping in the other. Therefore there was need for a full system replacement with modern materials and technologies, making the system less water in combination with modern boiler equipment – will provide real fuel savings during the heating season due to the economical production of heat and its rational use.
Currently in school buildings and gardens have an old wooden windows do not meet modern requirements of energy saving – gapping, glass in one window, drafts, which are even attaching a fix is impossible. Replacing them will significantly reduce heat loss. All activities that are planned under the project, but economic benefits are also the social side. Implementation of all activities will achieve the necessary sanitary facilities indicators that have a positive impact on children's health, and in some cases even fully use some space for the heating season.
