Abstract
The utility model discloses a pneumatic testing platform for a single/double-U joint of a ground source heat pump. The pneumatic testing platform comprises a first cylinder, a second cylinder, a testing mechanism and a water channel, wherein the first cylinder is connected with the top of the testing mechanism; the second cylinder is connected with a main body of the testing mechanism; and the water channel is formed below the testing mechanism. The pneumatic testing platform can fully detect a product, and is easy and quick to operate and high in test efficiency.
Description
Technical field
The utility model relates to the earth source heat pump field, relates in particular to the pneumatic test platform of a kind of earth source heat pump list double-H groove weld joint.
Background technology
At present, the product of earth source heat pump is most of to adopt injection machine production, and the product that injection moulding is produced presents big in batches characteristics.When last hydraulic test bench is tested, can not examine entirely one by one, can only inspect by random samples.Cause problematic product to come into the market easily like this, produce hidden danger of quality.Whether present earth source heat pump list double-H groove weld joint test sweat soldering place both domestic and external exists defectives such as rosin joint or pore all to adopt sampling observation, is difficult to find defective product.But present stage is not found the machine of market test products rosin joint on sale.
The utility model content
The purpose of the utility model is to provide a kind of earth source heat pump list double-H groove weld joint pneumatic test platform, realizes the complete detection to the earth source heat pump product.
In order to realize above-mentioned purpose; Adopt following technical scheme: the pneumatic test platform of a kind of earth source heat pump list double-H groove weld joint; Comprise first cylinder, second cylinder, mechanism for testing and tank; Said first cylinder is connected with the mechanism for testing top, and second cylinder is connected with the mechanism for testing main body, and tank places the mechanism for testing below.Product is placed in the mechanism for testing, and first cylinder is used for product compressed makes it sealing, second cylinder control mechanism for testing above tank with tank in back and forth movement.
Said mechanism for testing is provided with moving plate, and moving plate is provided with air admission hole, and air admission hole is used for test products is carried out gas pressurized.
Compared with prior art, the utility model can be examined product entirely, and simple and efficient to handle, and testing efficiency is high.
Description of drawings
Fig. 1 is the principle assumption diagram of the utility model;
Fig. 2 is the enforcement structural drawing of the utility model;
Fig. 3 is the double structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
The principle of the utility model is as shown in Figure 1; Comprise first cylinder 1, second cylinder 2, mechanism for testing 3 and tank 4; Said first cylinder 1 is connected with mechanism for testing 3 tops; Second cylinder 2 is connected with mechanism for testing 3 main bodys, and tank 4 places mechanism for testing 3 belows, and test product 5 is placed in the mechanism for testing 3.
The enforcement structure of the utility model is as shown in Figure 2.The test products process may further comprise the steps:
S1 is placed into test product in the mechanism for testing 3, through the air admission hole on the moving plate 31 of mechanism for testing 3 test product is carried out pressurising 6-8 kilogram gas.
Test product compresses in 1 pair of mechanism for testing of S2 first cylinder 3, makes it to seal pressurize.Observe and whether have leakage point: if exist the leak point on sealing surface, scalable first cylinder 1 increases the pressure to mechanism for testing 3; If there is not the leak point, can reduce the admission pressure of first cylinder 1.
S3 is delivered to mechanism for testing in the tank 4 by second cylinder 2 after the pressurize of survey product, and the water level of tank 4 will be higher than product sweat soldering place.Observing in the tank has or not bubble to emerge: if there is bubble to emerge, explain that then there is weld defects in sweat soldering place; If no bubble is explained and is not had the welding defective.
If adopt the double test structure, can further improve testing efficiency, as shown in Figure 3.One second cylinder 2 cooperates two first cylinders 1, two mechanism for testing 3 and two tanks 4, but double is tested simultaneously.
Claims (3)
1. pneumatic test platform of earth source heat pump list double-H groove weld joint; It is characterized in that comprise first cylinder, second cylinder, mechanism for testing and tank, said first cylinder is connected with the mechanism for testing top; Second cylinder is connected with the mechanism for testing main body, and tank places the mechanism for testing below.
2. test platform according to claim 1 is characterized in that said mechanism for testing is provided with moving plate.
3. test platform according to claim 2 is characterized in that, said moving plate is provided with air admission hole.
