Problems solved by technology

[0003] At present, there are many types of electric heating tubes, but there is no comprehensive testing device that can effectively test the safety performance of electric heating tubes.
The current safety performance testing methods of electric heating pipes and corresponding disadvantages are as follows: 1. When measuring water pressure, install the electric heating pipe products on the electric water heater, conduct daily tap water pressure test, and accept it without leaking water, without testing its safety indicators ;2. When mea

Abstract

The invention aims at providing an electric heating tube testing device and method. The electric heating tube testing device and method are used for comprehensively and reliably testing the safety performance of electric heating tubes. The electric heating tube testing device comprises a metal testing barrel with a movable barrel cover. The upper portion of the testing barrel is connected with a liquid inlet pipe and an air exhaust pipe. The liquid inlet pipe is provided with a liquid inlet valve. The air exhaust pipe is provided with an air exhaust valve. The lower portion of the testing barrel is provided with a liquid outlet pipe and an air inlet pipe. The liquid outlet pipe is provided with a liquid outlet valve. The air inlet pipe is provided with an air inlet valve. The testing barrel is connected with an air pressure gauge, a hydraulic pressure gauge and a temperature gauge through pipelines. The barrel body of the testing barrel is connected with an earth terminal through a wire. The testing barrel is provided with a testing terminal communicated with the interior and the exterior of the testing barrel. The electric heating tube testing device is applicable to testing of various electric heating tubes, the electric heating tube testing method is convenient to implement, reliable and reliable, and factory testing of the electric heating tubes can be achieved.

Description

technical field [0001] The invention belongs to the technical field of electric heating tube testing, and in particular relates to an electric heating tube testing device and a testing method thereof. Background technique [0002] The electric heating tube (tubular electric heating element) is made of a metal tube (including stainless steel and copper tube), and the spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is uniformly distributed along the central axis of the tube, and the gap is filled and compacted with good insulation Magnesia sand with thermal conductivity, and the two ends of the nozzle are sealed with silica gel. This electric heating tube can heat air, metal molds and various liquids. [0003] At present, there are many kinds of electric heating tubes, but there is no comprehensive testing device that can effectively test the safety performance of electric heating tubes. The current safety performance testing methods of electric heat...
