Utility model content
The utility model provides a kind of fuel tank platform of comprehensively hunting leak, and can guarantee that fuel tank sealing after welding (or socket), fastness meet industry standard requirement.
In order to realize the purpose of this utility model, intend adopting following technology:
The fuel tank platform of comprehensively hunting leak, mainly comprises base (1), main water box (3) and control module (8), and main water box (3) is placed on base (1).
Described base (1) is also provided with vacuum pump (2), and vacuum pump (2) is connected with control module (8), and when the vacuum values in fuel tank reaches the setting value of control module (8), control module (8) cuts off power automatically, closes vacuum pump (2);
On described base (1), be also provided with secondary water tank (7), between main water box (3) and secondary water tank (7), be provided with suction pump (9) and communicating pipe (10), in secondary water tank (7), be provided with liquid level sensor (70), liquid level sensor (70) is connected with control module (8);
Described main water box (3) is also provided with fastening frame (4), and fastening frame (4) is controlled by cylinder.
Further, control module (8) is comprised of vacuum pump control module and suction pump control module, vacuum pump control module is controlled the switching of vacuum pump (2), the switching of suction pump unit controls suction pump (9), and liquid level sensor (70) is connected with suction pump control module.
Further, communicating pipe (10) is also provided with one-way on-off valve (11).
The advantage of technique scheme is:
1, on base, be provided with secondary water tank, before fuel tank being put into main water box leak detection, water in main water box can be by the secondary water tank of suction pump suction, so just be easy to fuel tank to put in main water box, while having avoided water tank of traditional leak detection platform to put into fuel tank, because buoyancy of water causes fuel tank, put into difficult problem.
2, on base, be provided with vacuum pump, vacuum pump can vacuumize fuel tank, can carry out fastness test to fuel tank.
3, the utility model is simple in structure, and cost is low, easy to implement, can carry out effectively leak detection and fastness test to fuel tank.
Accompanying drawing explanation
Fig. 1 shows the utility model structural representation.
Embodiment
The fuel tank platform fuel tank platform of comprehensively hunting leak of comprehensively hunting leak, mainly comprises base (1), main water box (3) and control module (8) as shown in Figure 1, and main water box (3) is placed on base (1).
Base (1) is also provided with vacuum pump (2), vacuum pump (2) is connected with control module (8), particularly, be connected with the vacuum pump control module in control module (8), during leak detection, when the vacuum values in fuel tank reaches the setting value of control module (8), control module (8) cuts off power automatically, closes vacuum pump (2);
On base (1), be also provided with secondary water tank (7), between main water box (3) and secondary water tank (7), be provided with suction pump (9) and communicating pipe (10), in secondary water tank (7), be provided with liquid level sensor (70), liquid level sensor (70) is connected with control module (8);
Main water box (3) is also provided with fastening frame (4), and fastening frame (4) is controlled by cylinder.
During leak detection, first suction pump (2) is opened, suction pump (2) is pumped into the water in main water box (3) in secondary water tank (7), in secondary water tank (7), be provided with liquid level sensor (70), when the water level in secondary water tank reaches liquid level sensor (70) position, now liquid level sensor (70) sends and feeds back signal to control module (8), and control module (8) cuts off the power of suction pump (2) automatically, and suction pump (2) quits work.Now main water box (3) is in low-water level state as shown in the figure.
After this start to put into fuel tank, because the water level of main water box (3) is now in low-water level, fuel tank is easy to put into, put into after fuel tank, cylinder is controlled fastening frame (4) running, fastening frame (4) clamps fuel tank, clamp after fuel tank, open communicating pipe the one-way on-off valve (11) on (10), water in secondary water tank (7) starts to return main water box (3), simultaneously, high-voltage tube (5) is accessed to fuel tank by high pressure sealing joint (6), be filled with gases at high pressure, water level in main water box (3) rises to while checking water level, close one-way on-off valve (11), standing 30s, see whether fuel tank commissure has bubble to emerge, as do not have, prove that fuel tank leak detection is qualified.
Hunt leak qualified after, carry out fastness test, now open again suction pump (9), when main water box (3) middle water level drops to low-water level, take off high-voltage tube (5), vacuum pump is connected with fuel tank, open vacuum pump (2), when the vacuum values in fuel tank reaches the setting value of control module (8), control module (8) cuts off power automatically, closes vacuum pump (2), now observes under extraneous atmospheric pressure, whether fuel tank has distortion, with this, judges the fastness of fuel tank.
Above embodiment only explains to a kind of preferred version of the utility model, the essence of utility model is not made to restriction, and above test process also can first carry out vacuum test, then the test of hunting leak.
The utility model is simple in structure, and cost is low, easy to implement, can carry out effectively leak detection and fastness test to fuel tank.
