Automatic steel pipe underwater airtight testing machine

Abstract

The invention relates to steel pipe quality detection equipment and specifically relates to an automatic steel pipe underwater airtight testing machine. For the automatic steel pipe underwater airtight testing machine, a steel pipe holding rack is arranged at the outside of a first side plate for a water storage tank; one or more liftable pipe taking supports are arranged on the first side plate; the back end of each liftable pipe taking support extends to a steel pipe at the forefront end on the steel pipe holding rack; when each liftable pipe taking support rises, the steel pipe at the forefront end on the steel pipe holding rack is ejected upward to enable the steel pipe to prevent from restriction of a baffle plate; and then the steel pipe falls off along the inclined plane on each pipe taking support and falls on each steel pipe support to accept airtight detection. The automatic steel pipe underwater airtight testing machine is provided with a steel pipe holding rack; steep pipes are arranged on the steel pipe holding rack; and the steel pipes can be taken through the lifting movement of the pipe taking supports so that automatic taking and putting operation of the steel pipes can be realized. When the automatic steel pipe underwater airtight testing machine is used, manual work is only required for putting a plurality of steel pipes on the steel pipe holding rack, so that the efficiency for batch test is improved.

Description

technical field [0001] The invention relates to a steel pipe quality testing device, in particular to a fully automatic steel pipe underwater airtight testing machine. Background technique [0002] In the existing steel pipe production process, since the steel pipe is generally used for liquid transportation, after the steel pipe is produced, the air tightness test is generally required. For example, when the steel pipe is applied to various types of heat exchangers, evaporators, and condensers, If the airtightness of the steel pipe is not good, there will be leakage of liquid, which will affect the normal operation of the equipment. The existing air-tightness test is generally an underwater test. The two ends of the steel pipe are closed in water, and pressurized air is injected into the steel pipe. At this time, observe whether there are bubbles on the side wall of the steel pipe. If there are bubbles, it indicates There are gaps on the steel pipe, which is a substandard ...
