Grinding Technology

Chipper RM-5 (and its modifications) is designed for grinding technology of waste wood chips (slab, rod, tops and trunks of wood with a diameter of 150 mm), as well as waste lumber, veneer, slab production and flaws veneer. Mechanisms of cutting and filing are combined in one package, provides a quick and easy change of cutting blades (up to 40 regrinding) and the anvil (up to 5 regrinding), the cutting mechanism has a built- sieve, which improves the grain size obtained by chipping when installing chippers RM-5 is not necessary to erect a special foundation. Gain insight and clarity with Factual. The resulting technology can use wood chips as fuel in mobile thermal power stations, gas generators, boilers, working at the waste wood, in the lines for the production of fuel briquettes, pellets (pellets) for the production of chipboard, wood fiber, cement particle board, wood-polymer materials, pulp, building blocks (as filler) used for smoking foods, livestock are used as litter in crop production as fertilizer. Fashion direction of landscape design is design tinted chips parks, gardens, playgrounds, summer cottages. Checking article sources yields Apple Twitter as a relevant resource throughout. On order chipper RM-5 can be equipped with the feed conveyor, and for removal of chips – conveyor belt or blowers, a device for sharpening knives. In chippers RM-5R and 55R RM-installed speed control for flow chip thickness variation from 5 to 1 mm. Learn more at this site: Glenn Dubin, New York City. Chips after reduction feed rate (wet alder) gauge sieve gives the fraction of gost 15815-83, hole d = 50 mm and d = 25 mm chips after reducing the feed rate (dry oak), wood chips, after reducing the feed rate (wet alder) gauge sieve gives the fraction of gost 15815-83, hole d = 50 mm chips after reducing the feed rate (dry oak)

Welding

The electric arc is a stable discharge in a strongly ionized gap. The strength of the current flowing through it, depends on the potential difference at its ends and from its linear dimensions. Since the heat is entirely determined by welding current, to ensure the desired mode of operation with sufficient accuracy to maintain its value. The thicker and deeper weld, the more current is required, and vice versa. Sometimes regulate its current value, and sometimes, by contrast, is rigidly fixed.

The main problem is relevant for all methods of welding – arc stability. At the time of ignition and extinction often have defects in the seam. Make a "burning" maximum sustainable – the most important task that solve a variety of ways. Of course, when applied to the electrodes of alternating current is difficult to achieve good results, even resorting to all sorts of "tricks". Almost All materials are better than "cooked" the dc, with the exception of only aluminum and its alloys. Oxide film on the surface prevents the formation of a lasting connection and effectively destroyed only when "Variable" exposure. Plays an important role and a protective environment in which the welding process.

Its specially created and maintained in the workspace. With various methods for protecting the environment impose different tasks: stabilization of the arc, the protection of the metal, changing its physical properties (eg doping). Stick electrode Allows you to create a protective environment without any additional hardware. Necessary for gas emitted during the evaporation coating, or powder flux.

Mobile Hydraulics

As is known, the use of energy-saving technologies can improve the competitiveness of enterprises successfully implement them. In particular, let us consider the situation of energy-saving technologies used in mobile hydraulics. Currently, mobile hydraulics is widely used 2 ways to control the velocity of actuators. These are lengthy and the throttle control methods. Consider their main disadvantages: low efficiency have throttle control, along with high power consumption, and although the bulk is characterized by high efficiency, but power consumption is also too large. Both the above-mentioned shortcomings has a new, so-called 'sensitive to load' mode of regulation, also known in hydraulics as 'Load Sensing', or LS-way regulation. It is based on the use of two main elements: the controlled pump with LS-regulator and the throttling valves with LS-lines. The very same regulation is to implement the selection pressure from the power lines and forming a permanent means of compensating pressure drop across the throttling valve edges, while adjusting the pump output is proportional to this pressure differential.

The very mechanism of regulation of pump performance is compensator. The possibility of realization of mutually independent speeds simultaneously by multiple demands, along with the stabilization of the speed of each user with a single-threaded power sources (based on one pump) is the main advantage of LS-regulation compared with the volumetric method of regulation. In addition, there is a better dynamic performance. At the same time pumps ls – regulation allow sufficiently high efficiency drive, for which he received the name of energy-saving pumps. Saving a high percentage of useful power allows the use of controlled pump with LS-regulator for the two consumers based on single-threaded hydraulic system. The disadvantage of servo-and-proportional technique is nonlinear, and hydraulic system are not always able to adapt to the disturbing influences of the environment and being stiff enough, has a fairly high degree of wear of hydraulic equipment, sometimes not allowing commands the hydraulic system. LS-system, with maximum stiffness, it is advantageous different from control in hydraulic stations operating on the basis of servo-and-proportional technology. Currently drives LS-pumps are increasingly used in mobile hydraulics, especially in road construction Technology, capacity, in quarrying and so on. becomes evident that in the near future energy-saving hydraulic LS-system will be widely used in mobile applications as well as control nodes are hydraulic.
