The Matter

In general, what option to choose – it's up to vami.Tak vot.Esli do screed on different levels, then you can make the zero mark and the usual level of the form of hefty thick line, or the level of (excuse the tautology), built-in pravIlo.Ot this point and will be spoken as "dance" that is put beacons. Get more background information with materials from Dr. John Mcdougall. Lighthouses screed floor, you can make almost anything, such as of the guide profile 27 x 28. And you can of the special T-shaped guides provided for just such types of work as the alignment of the walls, floor or screed. Wooden beacons do not advise it, because even (indeed smooth) lumber – a rare phenomenon, and even if there is such, it is better to put it on something else than to spoil the solution. T-beacon set your feet up, in the sense of – foot, because it is one, at a level to the minimum thickness of floor screed to be not less than 15 mm, otherwise it will crumble later.

It is clear that the minimum thickness – it is just there, where was the highest point. Secure beacons best batches of the same solution, which will make the very floor screed, it is not necessary to use a different mix, especially in any case can not be mixed with gypsum cement mortars. I think you're out of school chemistry course should remember that lye with acid is not very friendly. In fairness, we must of course be noted that there are mixes cement with gypsum, moreover, in the production of the cement is also used plaster – it is one of the binding components, but one is a serious production, where the matter is not limited to the simple mixing of components, and another – an attempt to repeat at home, not knowing all the details and not having proper equipment.

High Pressure Hoses

The list of factors to consider when choosing a high-pressure hoses hoses. Mechanical loads. External forces can significantly reduce the service life of high-pressure hoses. Mechanical loads, which should be considered include excessive flexibility, twisting, looping, stretching or lateral loads, bending radius, and vibration. In order to avoid twisting, you may want to use on the sleeve fittings articulated or adapters. When choosing a sleeve for an unusual use, may require special tests.

Abrasion. Although the RMA is designed to arm a certain level of abrasion resistance, to protect it from excessive friction, which can lead to collapse, holes and cuts the outer layer. Robert Greene gathered all the information. Damage to the reinforcement will accelerate the wear sleeve. Proper end connection. Necessary to provide an accurate connection between the sleeve and the crimp sleeve is selected in accordance with manufacturer’s recommendations, backed by industry-standard tests.

Length. In determining the appropriate length sleeves should consider moving it, change in length under pressure, as well as the gaps between the high-pressure hose and machine. Specifications and standards. When choosing a high-pressure hose and fittings should be familiar with applicable government, industry standards and manufacturers’ recommendations. Fracking colorado does not necessarily agree. Clean the sleeve. Components of the sleeves may vary in the level of purity. One must be careful to hose connections have the same degree purity for a particular application. Welding and soldering. Heating galvanized parts, including fittings and adapters, above 232 C, for example, during welding or soldering may cause a selection of deadly gases. Specific conductivity. In some cases, in order to avoid an electric current requires that the sleeve was not conductive. In other cases, it is necessary that the sleeve has sufficient electrical conductivity to running down the static electricity. In cases where it is necessary that the sleeve was not electrically conductive, including work near power lines, you can only use a special non-conducting sleeve. Conductivity or no electrical hoses and fittings will depend on many factors and may be sensitive to change. These factors include, without limitation, the various materials used for manufacturing hoses and fittings, and how manufacturing (including moisture control), the contact with the sleeve fitting, age and degree of wear or damage, or other changes in the moisture content in the hole at a particular time and other factors. It was a list of bases factors that must be considered when selecting hoses and if you do not neglect the them, the high-pressure hose pprosluzhit you a long time.

Low Oil

DP jack 10 is comprised of base on which a plate 2 mounted hydraulic pump 3 and hydraulic cylinder telescopic working 4. Pump housing 5 is closed from the top cover 6, in which there are 7 to handle the transfer and installation of jacks and 8 control handle with a safety valve. Side of the pump housing 5 is the handle 9, is designed for installation in its operating handle 10. Handle 9 can be installed in two positions: upright and horizontal. For installation in a horizontal position to unscrew a nut 11 is mounted and rearranged the handle 9 to 1 … 2 hex shaft, and then fasten the handle to the new position of nut 11. Inside the housing 5 pump is equipped with two pumps dvuplunzhernyh: 12 Low pressure and high pressure outlet 13 14 and 15 reverse valves. Pump control shall handle 9 through a shaft 16 and yoke 17.

Handle 8 is associated with stem pressure relief valve 18. On the cover cap 6 has 19 to top up the oil pump inside the case. On the side of the housing 5 is installed plug 20, instead of which can be installed (via an adapter) to gauge pressure not less than 70 MPa for the control of operating pressure and adjust the safety valve 18. DP jack 10 operates as follows. Its installed between the sleepers on ballast aligned so that the telescopic 4 cylinder was under the sole of the rail. In the handle knob 9 is inserted working 10 and pumped oil to the desired height of the lift cylinder.

In the course of 12 plunger pump up the low-pressure oil that is in its working cavity has an upper volume and a plunger pulls over 13 high blood pressure. At the same time opens the inlet valve 14 and into the working cavity of the piston high-pressure oil supplied from the tank. When moving the plunger 12 down oil in its working chamber with low pressure pushes the piston plunger 13, forcing it to move down. Due to the change section of the plunger 13 of high pressure moving down, hands in return valve 15 oil (with a pressure of 2 times greater) in the cavity of the telescoping cylinder 4. In this case the inlet valve closes 14, cutting off the oil tank of the working cavity of the pump. During the return of the working pressure of the handle 10 the operator's hands through the shaft 16 and rocker 17 transferred to a second pump, and the process repeated. At the end of recovery you must click on the hilt of eight control and safety valve, pressing his foot on the cylinder, put it down. At excess pressure over Desktop offers a safety valve 18 and flows into the oil tank. What is fracking may find this interesting as well. Thus, the safety valve protects the hydraulic system of high pressure (above normal) and bypassed oil at the end of the work of cylinder to the tank. To adjust the valve 18 screwed his body. Ram DP 1.10 is a modification of the jack 10 without PD of the second stage (high pressure) pump. The work of this modification of the jack with low pressure carried out similar work the jack 10 with PD, except that it has no high-pressure plunger.
