Abstract
The invention discloses a cleaning method of a shock tunnel gun barrel. The cleaning method comprises the following steps of: 1) putting a polyurethane foam with an appropriate length into the section of the gun barrel to be washed, wherein the diameter of the polyurethane foam is slightly greater than that of the gun barrel; 2) highly pressurizing to fracture membranes so that the polyurethane foam moves at a high speed in the barrel driven by high pressure gas, thus cleaning the wall of the barrel. By adopting the cleaning method disclosed by the invention, high pressure gas with sufficient pressure is supplied by highly pressurizing to facture the membranes, so as to drive the polyurethane foam to move at a high speed in the gun barrel, and realize mutual friction between the foam and the wall of the barrel rub, thus achieving the effect of cleaning the wall of the barrel.
Description
Technical field
The present invention relates to a kind of cleaning method of shock tunnel gun barrel.
Background technology
Shock tube is after repeatedly Detonation Experiments, and gun tube inwall has a lot of carbon distribution and dirt, thus affects experiment effect.And how effectively to clean the difficult problem that big gun wall is puzzlement shock tunnel laboratory staff all the time.
Conventional cleaning gun tube method has two kinds: one to be utilize cloth to take turns two ends rope, and people or mechanical device pull at gun tube two ends to reach cleaning big gun wall object repeatedly.This method working strength is large, and cleaning performance is unsatisfactory.Two is the metallic brush polishing gun tube inwalls utilizing the dredging machine head transformed.This method has damage to tube wall, and the time of polishing cleaning is longer, and effect is also undesirable.
Summary of the invention
For prior art Problems existing, the object of the present invention is to provide a kind of cleaning method of shock tunnel gun barrel, can clean gun tube inwall rapidly, and cleaning performance is fine.
The method of a kind of shock tunnel gun barrel cleaning of the present invention comprises the steps:
1) in the section to be cleaned of gun tube, the polyurethane foam that one has suitable length is put into, suitable water is infiltrated on the surface of described polyurethane foam, the diameter of described polyurethane foam is slightly larger than the internal diameter of described gun tube, and the length of described polyurethane foam is 0.3 ~ 0.6 meter;
2) by high pressure rupture of membranes, make described polyurethane foam under gases at high pressure promote in pipe high-speed motion, thus tube wall to be cleaned, to remove gun tube inwall carbon distribution and dirt; The Stress control of described gases at high pressure is at 1 ~ 3 atmospheric pressure, and described speeds control is at 50 ~ 100m/s.
Preferably, be provided with a polyurethane foam receiver in the exit of described gun tube, this receiver offer the perforate in predetermined quantity and aperture.
The present invention utilizes high pressure rupture of membranes to provide the gases at high pressure of enough pressure, thus promotes polyurethane foam high-speed mobile in gun tube, and foams are with the mutual friction of tube wall phase thus reach the effect of cleaning tube wall.
Accompanying drawing explanation
Fig. 1 is the invention process view;
Fig. 2 is the effect photo of the gun tube inwall after cleaning.
Detailed description of the invention
As shown in Figure 1, the present invention adopts in the section to be cleaned of gun tube 1, put into the polyurethane foam 2 that has suitable length, and infiltrate suitable water on the surface of polyurethane foam 2, the diameter of polyurethane foam 2 is slightly larger than the internal diameter of gun tube 1.By high pressure rupture of membranes, make polyurethane foam 2 along arrow A high-speed motion in pipe under gases at high pressure promote, thus tube wall is cleaned.In embodiments of the present invention, the length of polyurethane foam 2 is 0.3 ~ 0.6 meter.Owing to having frictional force between polyurethane foam 2 and tube wall, be subject to omiting deformed dilation when gases at high pressure promote, therefore adopt diameter slightly larger than gun tube 1 internal diameter and length just can reach good fltting speed at the polyurethane foam 2 of 0.3 ~ 0.6 meter under lower gases at high pressure, thus carry out the cleaning of tube wall.
Like this, the pressure of gases at high pressure can control at 1 ~ 3 atmospheric pressure.In addition, the speed of polyurethane foam 2 preferably controls at 50 ~ 100m/s, due under this speed, polyurethane foam 2 can produce higher temperature with pipe friction on the one hand, so that the carbon deposit in the tube wall of gun tube 1 and Fouling Cleaning is clean, also can not produce high temperature because speed is too fast on the other hand and polyurethane foam 2 is burnt out.
In addition, as shown in Figure 1, be provided with a polyurethane foam receiver 3 in the exit of gun tube 1, this receiver 3 is cylinders 3 that an one end communicates with gun tube 1, and the barrel of cylinder 3 offers the perforate 4 in predetermined quantity and aperture.Like this, by quantity and the aperture of perforate 4, the fltting speed of polyurethane foam 2 in gun tube 1 can be controlled.
Finally blow residue off with pressure-air, with air blast and heater, gun tube is dried up.Fig. 2 is the effect photo of gun tube 1 inwall after cleaning.As shown in Figure 2, after pressure-air promotion foams cleaning gun tube 2 ~ 3 times, gun tube inwall carbon distribution and the dirt overwhelming majority are eliminated, and it is obviously better that the method wipes gun tube method cleaning performance than above-mentioned tradition; Owing to having a small amount of polyurethane particles to remain in above tube wall after the high-speed friction of foams and tube wall, then can be washed out by pressure-air.
The present invention's pressure-air (2 atmospheric pressure of in fact only having an appointment) promotes foams, and energy is large, speed is fast, air cleaning and safety.In addition, if receiver 3 just can realize the control of speed and recycle polyurethane foam 2, foams with after can repeatedly use through cleaning, therefore it is lower to wipe big gun cost.
