Description
Technical field
The utility model relates to a kind of acid value of petroleum neutralizer metering method and device, be specifically related to steam turbine oil, acid value of transformer oil determination method (BTB method) is measured with neutralizer, the milligram number of neutralizer is gone out, to obtain the acid number of sample in order to accurate measurement.
Background technology
At present, in steam turbine oil, acid value of transformer oil determination method (BTB method), the metering method of neutralizer has two kinds, one is the metering of pure peristaltic pump, after peristaltic pump liquid feeding, by simple time measurement, namely pass through syringe needle with the neutralizer of fixed flow rate, after Dose times, be multiplied by the flow of unit interval, be converted into the milligram number of neutralizer, the method is easy to realize, and cost is minimum, and thus usable range is the widest, but stable, the timing start-stop of its measuring accuracy liquid body flow velocity is accurate, and the factors such as pipeline bubble are larger;
Another kind method is still uses peristaltic pump liquid feeding, but adopt photoelectric technology ripe at present to detect syringe needle and drip number, the milligram number of neutralizer is obtained by counting and syringe needle bore, the method is improved simple time measurement, the data obtained are more accurate, but owing to being milligram metering, neutralizer syringe needle bore is less, dropping liquid must be on the perpendicular line of transmitting and receiving straight line of photoelectricity, otherwise photoelectricity cannot detect, thus producer usually when dispatching from the factory, syringe needle to be mixed up blend compounds fixing dead, client cannot be adjusted, but because mounting and adjusting is bad, the problems such as transport loosens, when often causing client to use Photoelectric Detection less than or can't detect once in a while, measurement result is caused to be forbidden, thus the method is not still widely adopted in the exploratory stage.
In addition, the upper liquid method of peristaltic pump, upper liquid constant airspeed non-adjustable (otherwise measuring inaccurate by first method), but cross slow drip speed also can make Photoelectric Detection less than, the chemical reaction that excessive velocities then participates in due to neutralizer not exclusively causes measurement result bigger than normal, and peristaltic pump tube is owing to extruding the problem long-term existence being easy to damage simultaneously.
Utility model content
In order to solve existing neutralizer measuring apparatus Problems existing, the utility model uses new metering method and brand-new structural design, adopt the mode of liquid atmospherically of filtering moisture, neutralizer is sent into syringe needle, by in adjustable and the structure of drop speed and needle position, make optoelectronic switch be easy to detect that dripping of neutralizer counts, go out the milligram number of neutralizer according to the number detected and syringe needle calculation of diameter, thus obtain the acid number of sample.
Particularly, the utility model provides a kind of acid value of petroleum neutralizer measuring apparatus, described device comprises following structure: air pump filters gas cylinder and neutralizer bottle by quick connector and draft tube series connection, neutralizer bottle connects neutralizer syringe needle by feed tube, filtering the centre of gas cylinder and neutralizer bottle, by three-way connection parallel connection access normally open valve and flow speed control valve, syringe needle is installed on holder by adjusting seat, and the optoelectronic switch below syringe needle is installed in the bottom stage of holder.
When air pump and normally open valve energising, the pressure of air pump enters the alkaline solution in filter gas cylinder, filter the air pressure after moisture and enter neutralizer bottle, neutralizer is made to be pressed into syringe needle, now optoelectronic switch detects that dripping of syringe needle counts, and when acid number has been tested, closes air pump and normally open valve, now neutralizer bottle is emptying by normally open valve with the pressure in filter gas cylinder, can not make liquid backflow.
Also should do following adjustment before first use, the first, rotate the knob of flow speed control valve, the size of neutralizer bottle air pressure is entered by adjustment, regulate the speed of syringe needle dropping liquid per second at 2 ~ 3, the second, by regulating the position of adjusting seat, syringe needle dropping liquid is detected by optoelectronic switch.
Described filter gas cylinder and neutralizer bottle have the hermetically-sealed construction of gas-liquid, and normally open valve and flow speed control valve is parallel with between the two, in filter gas cylinder, air pressure directly enters the alkaline solution of bottom, overflow gas enters neutralizer bottle top from top, force bottom neutralizer to be input to syringe needle, flow speed control valve regulates the size entering neutralizer bottle air pressure, and normally open valve is when stopping pressurization, make the pressure of filter gas cylinder and neutralizer bottle emptying, prevent liquid backflow.
Described holder has T-slot, movable adjusting seat is housed in T-slot, be milled with the elongated hole for syringe needle movement bottom T-slot, the step below elongated hole is for installing optoelectronic switch, and T-slot top is opened threaded hole and fixed tight adjusting seat.
Described adjusting seat, syringe needle is installed at top, and both sides double-deck protruding being used for slides in the T-slot of holder; Upper strata is longer than by protruding lower floor, fixes with a upper screwed hole that is fixed.
The utility model adopts new upper liquid mode, solve the problem that peristaltic pump tube is easy to damage and constant flow rate, by the time regulating the speed dripping number to adapt to chemical reaction, thus the concentration of neutralizer need not be changed, measurement result is made more to meet standard, and make photoelectric detection component be easy to measure syringe needle by brand-new structure to drip number, reduce the probability broken down, operation and maintenance is convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model acid value of petroleum neutralizer measuring apparatus.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, " neutralizer measuring apparatus " air pump 1 in the utility model is connected by quick connector 12 and draft tube 14 and is filtered gas cylinder 2 and neutralizer bottle 3, neutralizer bottle 3 connects neutralizer syringe needle 6 by feed tube 9, filtering the centre of gas cylinder 2 and neutralizer bottle 3, by three-way connection 13 parallel connection access normally open valve 10 and flow speed control valve 11, syringe needle 6 is installed on holder 4 by adjusting seat 8, and the optoelectronic switch 5 below syringe needle 6 is installed in the bottom stage of holder 4.
