The advantages of this type of attachment the following: plates can be replaced or removed for inspection and there is no restriction on building height, high level of reliability because Each plate is fastened with anchor 4 screw anchors with screws. Using a hidden mechanical fastening plates, note the following: This method gives you less flexibility in planning pair of plates in comparison with other types of fasteners (recommended to lay perforated plates in advance) should carefully plan the run time of installation in connection with the special preparation of plates (holes) and the accuracy required for their installation and adjustment. For concealed rigid connection (mechanical / adhesive) each plate is attached to the horizontal profiles, special glue and additional mechanical fasteners in two points (the same type as in a mechanical system). Plates are normally supplied drilled. The advantages of this type of attachment: plates can be replaced or removed for inspection, reduce costs by reducing the number of holes, there are no restrictions on building height, high level of reliability, the preparation of plates is much smaller than in a mechanical fastening system. Must also consider the following points: costs increase as decrease the size of plates, less flexibility in the layout of interface board compared to other types of fasteners (recommended holes in the plates in advance), a more careful adjustment of plates performed somewhat more complicated. For concealed mounting in with gluing a plate attached to the profiles of vertical load-bearing profile with special glue. The horizontal profiles are not required.

The advantages of this type of attachment: plates can be replaced or removed for inspection and a significant cost reduction as the substructure (which does not contain horizontal sections) and on mounting plates and a significant reduction of time for preparation and installation – boards can be cut and finally processed on site, there are no restrictions on building height, relatively low-cost solution, even when the size of plates less than 600×600 mm. Must also consider the following points: plates can not be to check, you can not fit after the adhesive, and to replace them, boards need to be broken. For concealed mounting on studs (for plates of thickness 20-30 mm), drilled 4 holes (without trimming) in the horizontal edges. Plates are fixed vertical studs or pins, pre-attached to the wall. Plates are normally supplied pre-drilled, although they can be drilled directly on the site. Vertical and horizontal profiles are not required. Studs (upper / lower) are placed on adjustable brackets attached directly to the wall with screw fixings.

The advantages of this type of attachment: extremely easy to install, requires no fastening profiles, reducing the cost of installation and mounting plates, there are no restrictions on building height. Must also consider the following points: the system a little heavier than the other cases, you can use the insulating layer of 100 mm, less able to adjust the system. In order to replace or remove the plates, must be broken, at least one of them.

How do I invite guests to the wedding? (Wedding Invitations) As is known, the guests at the wedding celebrations are an integral part. Typically, the average wedding has about 30-35 people, so it's easy to forget someone inviting in the heat of the wedding preparations. You understand that then resentment will be for years to come … Aetna follows long-standing procedures to achieve this success. Moreover the guests themselves may simply confuse the wedding date or come to the wrong address. It is to avoid such cases and devised a special invitation to the wedding. It should be noted that it is important to take time to dispatch these 'napominalok'. The more family members and guests you invite, the more time you need to training. Indeed, some may live far away from your city or even abroad.

They need time to ponder a decision and get ready. Learn more at this site: W. James McNerney. First you have to make a list of prospective visitors and determine Who exactly do you want to write an invitation. You understand that if you are living with their parents, they probably should not send an envelope, although some may be willing to do so little surprise. Then you have to beat your list into 2 parts. First you send invitations by mail, so for this you need to buy an additional and envelopes, and the second you are going to visit the official invitation. Where can you find a special invitation, you ask? I think this is not the most difficult question that arises before us. Any office or department store sells a variety of wedding invitations.

Also, for example, I have seen stands in bookshops and supermarkets. There are even special shops selling all sorts of gifts, including wedding invitations. However, pay attention to the fact that not everywhere you can buy just the right amount of invitations. Usually they happen no more than 10-25 pieces of the same species. Prepare to be that you have to visit a couple of stores and buy a similar card if the number of your guests is more than 30 people. This is of course risky, but do not you want to All the guests were armed with the same invitation? If you want to come up with something special, you can order wedding invitations made by the original sketch. This, of course, will cost more, but your creative approach will appreciate your guests. Moreover, in this case, you can book an invitation to be printed. You just type in the names of relatives and guests. Also, you can even print their own on printer invitation text. Now modern printers include printing on postcards and envelopes of different formats. I want to give you good advice: try to buy the cards in special stores, as There you to invitation to everyone else and will make a free envelope. You remember that a good half of the guests will need to send an invitation in the mail? You will only buy brands and the trick is done. Order the production of wedding invitations with printed text.

The most effective is the compression-batch assembly; 5.Minimalnaya length of the pump should be achieved by increasing the number of revolutions. However, the dependence of wear on the frequency of rotation is a cubic, which requires the use of substandard materials that increase durability; 6.KPD pump also be increased by reducing the surface roughness of its working bodies. In the energy direction of the technical modifications can be summarized as follows: an increase in efficiency and pressure from reduced power and cost of operation and maintenance. In the energy used pumps to pump the central nervous system of cold water to 450S, to pump hot water pumps are used to operating temperature CNSG range of 45 to 1050S. Currently, there is a huge choice of CNS pump with different parameters for different needs. Modification of the central nervous system pumps will take place in several directions. Increase efficiency.

One of the characteristic methods of increasing efficiency for centrifugal pumps is turning the impeller. The specific selection of the impeller at the desired mode (supply and pressure) allows, especially for large pumps, to receive significant savings energy. Increased reliability. Reliability of the pump during operation is important. To increase the reliability of using different construction materials: lightweight aluminum for heavy construction work and Mines, durable cast iron to corrosive environment or work with sea water, stainless steel – to provide additional corrosion resistance and aluminum bronze – for the very corrosive. One of the areas of technical modifications may include the following improvements Application of a new liquid end (new impellers, guide vanes); installation of mechanical seals with flushing system in the process operation or gland seals, graphite, allowing the pump to work without leaks from seals lift once a year; installation on the shaft of the protective rubber rings to prevent erosion of the seats of the shaft and impellers; use of interstage seals carbide rings errozionnostoykih; installation site optimized discharge device; use as a connecting node (Pump motor) a flexible plate clutch; installation of the gauge axial shift with an automatic alarm permissible wear hydraulic balancing device. As a result of these modifications: increased service life of 2 – 2.5 times; expanded the permissible area of optimal; increased efficiency in the work zone operation; reduced vibration; reduced to a minimum external leakage; easy access to all sites; is simplified circuit assembly; improved design. Manufacture of pumps in special workshops, equipped with the most modern technological equipment. At all stages of production from the smelting metal to manufacture parts, assembly and testing of components and finished product provides complete control over all design and technological parameters. From the analysis of the Russian market of central nervous system of pumps can meet in the report of the Academy of IKAR industrial markets "Market pumps CNS in Russia."
