Abstract
The utility model discloses a power testing device of a PTC heating pipe. The power testing device includes a plurality of testing assembly groups, a water tank, a power testing instrument, and a circuit control system. The testing assembly includes a return line, a solenoid valve, and a water pump. The two ends of the return line are connected with the water tank respectively. The solenoid valve and the water pump are arranged on the return line. A to-be-tested PTC heating pipe is arranged between the solenoid valve and the water pump. The solenoid valve is connected with the circuit control system. The to-be-tested PTC heating pipe is connected with the power testing instrument. The power testing instrument is connected with the circuit control system. The water pump is connected with the circuit control system. The advantages of the power testing device of the PTC heating pipe are that the mass simultaneous testing of the PCT heating pipe can be carried out, the efficiency is high, and the testing data is accurate.
Description
Technical field
The utility model relates to a kind of power test equipment, especially relates to a kind of PTC heating tube power test equipment.
Background technology
Along with the application rapid growth of PTC heating tube on Pediluvium apparatus, production firm presses for the production efficiency that improves heat-generating pipe.Because the singularity of PTC, marked change can take place with the variation of radiating condition in its power.Therefore accurately measure its power and become a critical technological point.At present the PTC heating tube is adopted the installation test mostly, be about to the PTC heat-generating pipe and be contained in its power of test on the Pediluvium apparatus.The testing efficiency of this kind power test is very low, and accuracy is not high yet, the incompatible production in enormous quantities in enormous quantities.
Summary of the invention
The utility model technical matters to be solved provides a kind of testing efficiency than high PTC heating tube power test equipment.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of PTC heating tube power test equipment; It is characterized in that comprising many group test suites, water tank, power measuring and circuit control system; Described test suite comprises return line, solenoid valve and water pump; The two ends of described return line are communicated with described water tank respectively, and described solenoid valve and water pump are arranged on the described return line, and PTC heating tube to be tested is arranged between described solenoid valve and the water pump; Described solenoid valve is connected with described circuit control system; PTC heating tube to be tested is connected with described power measuring, and described power measuring is connected with described circuit control system, and described water pump is connected with described circuit control system.
The water inlet end of described return line is arranged under the liquid level of water tank, and the water side of described return line is provided with on the liquid level of water tank.
Test suite quantity is 20 groups.
Described water tank is provided with the water surface elevation control system.
Described water tank is provided with temperature control system.
Compared with prior art, the utility model has the advantages that PTC heating tube to be measured is installed between solenoid valve and the water pump, press start button.Solenoid valve is opened, and the water in the water tank gets in the return line, and water pump starts voluntarily draws back water tank with water, forms a complete water cycle.The circuit control circuit begins to the power supply of PTC heat-generating pipe, and power instrument begins detection power.Work as power stability, power instrument automatically locks the numerical value that current detection arrives.PTC heat-generating pipe outage then.Water pump, closed electromagnetic valve, test is accomplished.After the operator presses start button, can directly carry out next group and detect, need not to wait for the test result of current testing group.Can be to the test simultaneously in enormous quantities of PTC heating tube, efficiency ratio is higher, and test data is more accurate simultaneously.
