Abstract
The invention relates to a liquid amount checking method for a gun re-entering machine, which utilizes the initial air pressure and the air pressure after a gun body sits for a certain distance to calculate the liquid amount through a formula. The invention can measure the liquid quantity by using the fact that the gun body moves a certain distance at will, and the liquid quantity can be measured only by changing the volume of the gas in the re-feeding machine without being limited to the traditional 250mm, so that the method is simpler and more convenient in the actual operation process. The invention makes the service operation more convenient and can be used for artillery support of troops.
Description
Technical field
The invention belongs to weaponrys to ensure field, and in particular to a kind of cannon recuperator means liquid measure inspection 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.
The duties often to be carried out using the cannon of liquid vapour-pressure type recuperator means work is to check its liquid measure, works as liquid measure
Cannon cannot work normally when abnormal.Currently, the common method of liquid vapour-pressure type recuperator means liquid measure inspection is as follows: pacifying first
It fills air gauge and reads initial gas pressure value, then manually sitting back method reads air gauge numerical value after making barrel recoil 250mm again,
Recuperator means liquid measure can be determined with the liquid measure inspection table on the two atmospheric pressure values control cannon, or the two atmospheric pressure values are inputted
Special calculator can also determine recuperator means liquid measure.
The most difficult operation of recuperator means liquid measure inspection is artificial recoil, is turned with double-purpose pump electrolyte filling method or ratchet spanner
Screw means not only need to expend very big physical strength, and the time used also wants dozens of minutes.In order to improve the efficiency in artificial recoil,
Hydraulic pump or pulsometer are generallyd use at present, makes barrel recoil with the mode of manual manipulation.Advantage is that barrel recoil velocity adds
Fastly, the disadvantage is that being difficult accurately to control the recoil length of barrel, when recoil length is close to 250mm, it is necessary to which small heart manipulation, one is small
Heart recoil length just has exceeded 250mm.
It can be seen that recoil length 250mm specified in current recuperator means liquid measure inspection method is brought very very much not to actual use
Just.Screw means are turned to double-purpose pump electrolyte filling method or ratchet spanner, this length seems too long；To manual manipulation hydraulic pump
Or the method for pulsometer, and be difficult to control length accuracy.If recoil length is changed to can arbitrarily to change in a certain range
Numerical value can select a shorter recoil when then turning screw means recoil using double-purpose pump electrolyte filling method or ratchet spanner
Distance saves manpower and time；When using the method recoil of manual manipulation hydraulic pump or pulsometer, without deliberately controlling recoil
Precision, any one recoil.Here it is core of the invention thoughts.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of recoil length is random, the simpler cannon of mode of operation
Recuperator means liquid measure inspection method.
The technical scheme adopted by the invention is that: a kind of cannon recuperator means liquid measure inspection method comprising following steps:
Step 1: installing air gauge on liquid vapour-pressure type recuperator means, and measure initial gas pressure p0；
Step 2: manually making the random recoil a distance l of barrel, air gauge numerical value p at this time is read1；
Step 3: calculating liquid measure using formula (1)
In formula, Vy--- liquid volume, i.e. liquid measure；
V --- recuperator means total volume；
Af--- piston area；
Step 4: barrel resets, air gauge is removed.
In the present invention, the range of distance l is 20mm or more.
The positive effect of the present invention are as follows: the present invention arbitrarily moves a distance using barrel, as long as being able to achieve in recuperator means
Gas volume changes, and can measure liquid measure, it is not necessary to be confined to traditional 250mm, simpler, side in actual mechanical process
Just.The invention enables duties operation it is more easy, can be used for the cannon guarantee of army.
Specific embodiment
The present invention includes the following steps:
Step 1: installing air gauge on liquid vapour-pressure type recuperator means, and measure initial gas pressure p0。
Step 2: manually making the random recoil a distance l of barrel, air gauge numerical value p at this time is read1, the range of l is
20mm or more.
Step 3: calculating liquid measure using formula (1)
In formula, Vy--- liquid volume, i.e. liquid measure；
V --- recuperator means total volume；
Af--- piston area.
Step 4: barrel resets, air gauge is removed, completes measurement.
In step 2, artificial recoil can turn screw means with double-purpose pump electrolyte filling method or ratchet spanner, can also
Using the method for manual manipulation hydraulic pump or pulsometer.
In step 2, the moving distance of barrel be not required for it is fixed, as long as in recuperator means gas volume relatively after
It changes before seat, the equation of gas state can be established, acquire the volume of gas, and then acquire liquid measure.The V and A in formulafRoot
It can be immediately arrived at according to recuperator means model.
For example, the liquid vapour-pressure type recuperator means of certain type cannon, measures p0=6.3MPa, barrel recoil 50mm, measures p1
=6.5Mpa, so that the liquid measure for calculating recuperator means is 13.7 liters.
The present invention provides a kind of new method for cannon recuperator means liquid measure inspection, and duties operation is more easy, can be used for
The cannon guarantee of army.
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.
