In a note it is told about a solution of the problem of the intraeconomic accounting of diesel fuel by means of the domestic 1UA-MM device.
So far the question of the accounting of the spent fuel in agricultural production wasn’t so actual because of its relative low cost of the "Soviet" way of managing on the village with its principle A crop – at any cost
So far the question of the accounting of izraskhodoyovanny fuel in an agricultural proizvodyostvo wasn’t so actual because of its otnositelyyony low cost of the "Soviet" way of managing on the village with its principle A crop – at any cost. But all changes … Our relation to a selyyosky economy changed also, today – it is the same business, as well as any other production, and there is enough kapiyotaloyemkiya.
According to an assessment of leading Ukrainian economists today in the budget agricultural a predpriyayotiya the share of expenses for fuels and lubricants makes from 30 to 60 % in a zayovisimost from account level at the enterprise and primeyonyaemy technologies of cultivation of agricultural products.
Many are engaged in a problem of the accounting of fuel firmy and the scientific organizations, including UKRNIIPIT of. L.Pogorelogo and KP MTS "Agricultural machinery". On KP MTS "Agricultural machinery" it was created engineering gruppa by which production tests of the device of the vnutrikhozyaystyovenny accounting of IVA-MM fuel (fig. 1) are developed, approved and carried out. During nayouchny searches more than twenty schetyochik of fuel Russian and foreign proizvoditeyoly were tested, four patents for the invention and five priorities for useful model, and only creation of the device of own design are received allowed dobitsya an acceptable ratio the price – quality.
It is necessary to note that IVA-MM flowmeter osnashhen the mechanical counter. At a flowmeter ustayonovka under a tractor cowl uslozhnyaetsya information reading, and at installation in a cabin – connection to fuel system of the engine.
Therefore experts of UKRNIIPIT of. L.Pogoyorelogo was developed the electronic RMT controler. In this case the sensor of a stream of fuel is mounted under a cowl, and in a tractor cabin ustanavlivaetsya the electronic block (controler), svyazanyony with the sensor by means of a cable.
There are two main options fuel sisyoty diesel engines: double-circuit (or deadlock) (fig. 2, and) and one-planimetric systems (fig. 2,).
Flowmeters of "IVA-MM" are intended for use with the engines having double-circuit fuel system. The foreign Minimat-DK device closest on a naznayocheniye firmy HansenhofElektronik (Germany) is intended for use with the engines having odnoyokonturny fuel system. The flowmeter with kontrolyolery "RMT" can work in any fuel sisteme, and at work in one-planimetric system two sensors of a stream are connected to the controler: one sensor – to the canal of supply of fuel, other sensor – to the canal fuel plum.
Value of fuel consumption (in liters) collects in non-volatile memory of the odnokriyostalny microcontroller and is deduced on an indikayotor. On the indicator the whole part (4 decimal categories) measured value) is constantly displayed, for viewing of a fractional part (3 signs posle a comma) are necessary to press the button on the device case.
The controler of a flowmeter of fuel in the structure has the converter of tension of an onboard network in constant tension 5 In with a wide range of entrance tension (from 7 to 16 In) and efficiency to 95 %. There is also a scheme of protection against "perepolyusovka" of a nayopryazheniye of a food and short-term emissions of a nayopryazheniye of an onboard network to 30 V.Pri a long vozyodeystviye of the increased tension the controler otklyuchaetsya. After tension removal the controler can be included again.
The general view of a set with the electronic controler is given on fig. 3. Into structure of a set enter: RMT controler; the sensor of a stream of fuel with the jack of hydroblows of "IVA"; a cable for connection to an onboard network and sensors; hoses and others komplektuyuyoshchy for sensor installation potoka.
Main technical characteristics of a set:
– range, l 0-9999,995;
– step-type behavior of counting, l 0,005;
– error of measurements, %, no more than 1;
– a supply voltage range, In 7,5… 15;
– result storage in non-volatile memory;
– protection against "perepolyusovka";
– protection against short-term increase of supply voltage till 30 Century.
In summary it is necessary to note that replacement of the mekhayonichesky counter with the electronic controler rasshiryaet scope of a flowmeter and prakticheski doesn’t influence the device price as a whole (for odnokonyoturny system).
