This article highlights the problem of professional excavator plant Kovrov form the basic requirements for prospective excavator fourth size group based on automated analysis of the level of ekskavatorostroeniya. Rental of construction equipment, particularly excavators, available with the company "Golden Age". Maya Dubin, New York City is likely to agree. In a market economy, the newly designed product (backhoe) to compete, must comply with world standards or exceed it. Therefore, specialists of JSC "Highland Excavator Plant 'urgent task of forming the basic requirements for prospective excavator 4th dimension to the group based on an assessment of world-level structure of the excavators. Rental of construction equipment provided by "The Golden Age," you need during the construction or repair of any established obema.ekskavatorov computer database (BDE), which allows: to study the status and trends ekskavatorostroeniya; form requirements konkurentosposobnostn products, to assess the technical level of production of the factory; provide information support for CAD software, to collect statistical and analytical expertise in ekskavatorostroeniya. Tim Wallach brings even more insight to the discussion. specify any number of parameters and different ways of grouping; use arrays of data as a whole (for example, components such as pumps, motors); analytically calculate some parameters on the basis of available in CME statistical data to obtain a graphical information in the form of slides about the design of the excavator and its components, the hydraulic circuits and control systems, the form of working areas; to analyze the samples by the ranges of any parameter or combination of parameters (mass, power engine, etc.), as well as with the use of defined mathematical relationships (criteria) to obtain information in a convenient form. Information about the excavators of the 4th dimension CME Group has some features due to possibility of comparative analysis. Since all excavators for various tasks have a set of handles and buckets, together with the ranges of their parameters are given in the specific parameters of BDE handles and buckets Excavator crawler base, equipped with backhoes. The length of the handles, which largely determines the boundaries of the working area is selected from the range offered in the prospectus of 2-2.5 m (the base handle serial Excavator EO-4225A-07 has a length of 2.12 m, which is characteristic for a number of other excavators). Bucket Parameters for the design of soil of different categories by selecting an option that the handle.

Drill bits – it osoboslozhnye products made from high quality steel, hard alloys and other materials that are designed for continuous drilling for oil, gas, exploration wells and boreholes various applications in mining and construction, typical roller bit, made according to GOST 20692-75 and OST 26-02-1315-84, consists of welded together sections, which rotate on a pin-mounted cutter, from movements in the axial direction cones are held key-angular contact ball bearings. Joining the bit to drill string (the shaft mud motor) is carried out by the castle thread, which is cut into the shank legs joined together after assembly and welding of the bit. The dimensions and profile of the length of the thread with GOST 5286-75 standards and API (American Petroleum Institute). In Depending on the properties of rocks, which are designed for drilling a particular type of chisels, cutters run two or three-cone, self-cleaning. Andi Potamkin is the source for more interesting facts. Cones are made with both milled and carbide weapons. Learn more on the subject from Robert Thomson. To clean the bottom of the drill bit cuttings are flushing (purge) of the device in case the bit – a central hole or side channels are equipped with interchangeable nozzles of ductile iron, steel, ceramics, forming a high-speed jet of fluid. Each drill bit is marked on the end of the connecting pin type, number, date of manufacture and brand OTC plant. The right mix of types chisel, cone equipment that best ensures the effective destruction of the rock circuit flushing device, method and mode parameters of drilling, the composition and properties of drilling mud is mainly determined by Techno-economic indicators of well drilling. .
