Abstract
The invention relates to a method for checking the liquid quantity of a gun recoil machine in consideration of temperature change. The invention introduces the temperature into an ideal gas state equation to measure the liquid quantity, removes the polytropic index which is difficult to determine and has more accurate measurement; meanwhile, a temperature sensor and a pressure sensor are arranged on the outer cylinder of the compound feeder to monitor the air pressure and the temperature in the compound feeder in real time, so that repeated installation and disassembly of a barometer are avoided; the length of the manual recoil seat is not limited to be 250mm, the manual recoil seat can be quickly and manually recoiled at any length, and the convenience of operation is improved.
Description
Technical field
The invention belongs to weaponrys to ensure field, and in particular to a kind of cannon recuperator means liquid measure inspection for considering temperature change
Checking method.
Background technique
Cannon recuperator means is the important component of Gun Anti-Recoil Mechanism, and function is to store energy at barrel recoil
Amount, barrel recoil releases energy afterwards in place by barrel pushed home.Medium-large caliber cannon generallys use liquid vapour-pressure type recuperator means,
Energy-accumulating medium is used as using gas (usually nitrogen), using liquid (recoil fluid) come sealing gas.Using liquid vapour-pressure type
The duties work that the cannon of recuperator means often to be carried out is to check recuperator means liquid measure, and when liquid measure is abnormal, cannon cannot
It works normally.
Currently, liquid vapour-pressure type recuperator means liquid measure checks that common method is as follows: installation air gauge first measures initial gas pressure
Numerical value, then manually sitting back method measures air gauge numerical value after making barrel recoil 250mm again, compares fire with the two atmospheric pressure values
Liquid measure inspection table on big gun can determine recuperator means liquid measure, or the two atmospheric pressure values are inputted special calculator, can also be true
Determine recuperator means liquid measure.Then barrel resets and removes air gauge.It can be seen that it is more troublesome to install and remove barometric operation.
In order to improve the efficiency in artificial recoil, hydraulic pump or pulsometer are generallyd use at present, with the mode of manual manipulation
Make barrel recoil.Advantage is that barrel recoil velocity is accelerated, the disadvantage is that being difficult accurately to control the recoil length of barrel, works as recoil length
When close to 250mm, it is necessary to which small heart manipulation, accidentally recoil length just has exceeded 250mm.Additionally, due to barrel recoil velocity
Fastly, gas compression speed is fast in recuperator means, and gas temperature may change before and after barrel recoil.For this temperature change,
At present by introducing polytropic exponent come approximate processing in cannon industry, but a index really correction factor, with it is many because
It is known as pass, is difficult accurate determination.
In short, artillery liquid vapour-pressure type recuperator means liquid measure inspection method has problems in that at present: needing to pacify installation and dismantling
Unload air gauge；Rapid artificial recoil is difficult to control accurately recoil length；It is more coarse to the processing of gas temperature variation.
Summary of the invention
It is multiple that technical problem to be solved by the invention is to provide a kind of cannons for measuring more accurate consideration temperature change
Into machine liquid measure inspection method.
The technical scheme adopted by the invention is that: a kind of cannon recuperator means liquid measure inspection method considering temperature change,
Include the following steps:
Step 1: in the outer cylinder mounting temperature sensor and pressure sensor of recuperator means, and measure initial gas pressure and initial
Temperature is denoted as p respectively0And T0；
Step 2: barrel recoil a distance l is recorded air pressure p at this time1With temperature T1；
Step 3: calculating the liquid measure of recuperator means using following formula
In formula, Vy--- liquid volume, i.e. liquid measure；
V --- recuperator means total volume；
Af--- recuperator means piston area.
The positive effect of the present invention are as follows: temperature is introduced The Ideal-Gas Equation to measure liquid measure by the present invention, is eliminated
Very doubt polytropic exponent, it is more accurate to measure；It is supervised in real time in recuperator means outer cylinder installation temperature and pressure sensor simultaneously
Air pressure and temperature in recuperator means are controlled, avoids installing and disassembling air gauge repeatedly；The present invention do not limit artificial recoil length as
250mm, rapid artificial recoil random length, improves the convenience of operation.
Specific embodiment
The present invention includes the following steps:
Step 1: in the outer cylinder mounting temperature sensor and pressure sensor of recuperator means, and measure initial gas pressure and initial
Temperature is denoted as p respectively0And T0(unit is Kelvin).Preferably, temperature, pressure integrated transducer is selected, and passes through data
Line, display pressure and temperature value, display screen are powered with battery in due course on a display screen.
Step 2: barrel recoil a distance l is recorded air pressure p at this time1With temperature T1(unit is Kelvin).Recoil
Mode of operation can be using hydraulic pump, pulsometer, screw rod, ratchet spanner, double-purpose pump etc..
Step 3: calculating the liquid measure of recuperator means using following formula
In formula, Vy--- liquid volume, i.e. liquid measure；
V --- recuperator means total volume；
Af--- recuperator means piston area.
Wherein, recuperator means total volume V and recuperator means piston area AfIt can be directly obtained according to the model of recuperator means.
As subsequent improvement, formula can be made into special calculator, input p0、T0、p1、T1Liquid outlet quantity can be calculated,
It is more convenient to use.
If recuperator means liquid measure is normal, barrel is resetted, standard value is arrived in adjustment recuperator means air pressure (i.e. first pressing)；If multiple
It is abnormal into machine liquid measure, then barrel is resetted, first adjusts recuperator means liquid measure to standard value, then adjust recuperator means air pressure to standard
Value.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to previous embodiment
Documented technical solution is modified or equivalent replacement of some of the technical features；And these are modified or replace
It changes, the spirit and scope for technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution.
