Description
Technical field
The utility model relates to motor test pump device, especially a kind of motor test pump device checked for complicated pipe welding seam.
Background technology
Pipe welding seam Weld Quality Inspection generally adopts pressure test method, pressure test for medium transmits pressure by pressuring pump in pipeline, has ne-leakage to reach the object of inspection weld seam with pipe laying weld seam under test pressure (design pressure) condition with liquid (usually using water).Common way is: water source input motor test pump, test pump is heightened hydraulic pressure and inputted pipeline to be detected, and in pipeline, hydraulic pressure carries out weld inspection after reaching design pressure.
Because face, storehouse constantly raises in Hydraulic and Hydro-Power Engineering, carry for convenience and detect, usually selecting portable motor test pump as pressure device, for the detection of pipe welding seam quality.Portable motor test pump has the advantages such as lightweight, volume is little, has the shortcomings such as power is little, uninterrupted working time ability simultaneously.And the dynamo-electric pipe laying buried underground in hydroelectric project, along with the rising of position in storehouse and the complicated of structure, pipeline is also in continuous rising, and pipeline and arm thereof also become changeable complexity; After adopting the press water after the pressure regulation of portable motor test pump of usual way to enter pipeline, the discrepancy in elevation due to pipeline is large and arm is many and complicated, need to overcome a lot of pressure influence factors and just can set up manifold pressure system, often need the voltage supply of lasting more than two days could meet the pressure of testing inspection, long continuous firing easily causes motor test pump burn-down of electric motor, and waste ample resources drops into, and affects construction speed.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of motor test pump device checked for complicated pipe welding seam, the problem directly easily causing device damage from motor test pump for press water duration length can be solved, ensure that pressure of supply water, ensure that pipe welding seam quality inspection; Structure is simple, be easy to operation, can reduce resource input, shorten the construction period, guarantee construction quality.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of motor test pump device checked for complicated pipe welding seam, comprises motor test pump,
Four-way connection left end is communicated with motor test pump by the first pipeline of band first valve;
Four-way connection right-hand member is communicated with pipe laying to be detected by the 3rd pipeline;
Four-way connection upper end is provided with tensimeter;
Four-way connection lower end is communicated with pressure water source by the second pipe of band second valve.
First valve is preferably ball valve.
Second valve is preferably ball valve.
The motor test pump device checked for complicated pipe welding seam that the utility model provides, taking, the pipeline be communicated with motor test pump is set press water is provided, the short time is continued for press water by the pressure water source be connected with second pipe, set up manifold pressure system to be detected fast, the motor test pump be communicated with second pipe can regulate, control hydraulic pressure in pipeline reaches design pressure, solve the problem directly easily causing device damage from motor test pump for press water duration length, ensure that pressure of supply water, ensure that pipe welding seam quality inspection; Principle is simple, and easy operation, while ensuring the quality of products, decreases resource input, reduces work on the spot difficulty.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of motor test pump device checked for complicated pipe welding seam, comprises motor test pump 3, it is characterized in that:
Four-way connection 1 left end is communicated with motor test pump 3 by the first pipeline 2 of band first valve 4;
Four-way connection 1 right-hand member is communicated with pipe laying 6 to be detected by the 3rd pipeline 5;
Four-way connection 1 upper end is provided with tensimeter 7;
Four-way connection 1 lower end is communicated with pressure water source 9 by the second pipe 8 of band second valve 10.
First valve 4 is ball valve.
Second valve 10 is ball valve.
Job step of the present utility model is as follows:
Step 1: install each parts of this utility unit, closes the first valve 4 on the first pipeline 2, opens the second valve 10;
Step 2: 9(such as storehouse, cut-in pressure water source look unfamiliar produce press water, rush hair machine press water etc.), then water supply start builds pressure;
Step 3: observe the data that four-way connection 1 upper end tensimeter 7 shows, after pressure is set up (a little less than design pressure), closes the second valve 10 on second pipe 8, withdraws pressure water source 9;
Step 4: open the first valve 4 on the first pipeline 2, supply water to motor test pump 3, according to the pressure that tensimeter 7 shows, fine setting motor test pump 3 exports hydraulic pressure, until meet the design pressure of pressure test pipeline, then pressurize;
Step 5: carefully check that the weld seam of pipe laying 6 to be detected is with or without percolating water, judges weld seam welding quality according to leakage scenarios.
Taking, the pipeline be communicated with motor test pump is set press water is provided, the short time is continued for press water by the pressure water source 9 be connected with second pipe 8, set up manifold pressure system to be detected fast, the motor test pump 3 be communicated with second pipe can regulate, control hydraulic pressure in pipeline reaches design pressure, solve the problem directly easily causing device damage from motor test pump 3 for press water duration length, ensure that pressure of supply water, ensure that pipe welding seam quality inspection; Principle is simple, and easy operation, while ensuring the quality of products, decreases resource input, reduces work on the spot difficulty.
