Document Type and Number:
WIPO Patent Application WO/2020/010843
Kind Code:
A1
Abstract:
An electrical pressure test pump, comprising: a main passage (11), a first passage (12) and a switch valve (15), the main passage (11) being used for connecting to a pipe system, and the main passage (11) being connected to the first passage (12) by means of the switch valve (15), the switch valve (15) being used for controlling the connection/disconnection of the main passage (11) and the first passage (12); and further comprising a second passage (13) that is in communication with the first passage (12) and a third passage (14) that is in communication with the main passage (11), the second passage (13) and the third passage (14) being connected by means of a power pump (16). And an electrical pressure tester, comprising an electrical pressure test pump and a liquid storage container (10). The electrical pressure test pump can complete automatic pressurization, improving the pressurization efficiency and speed. By controlling the connection/disconnection of the main passage (11) and the first passage (12) by means of the switch valve (15), the water intake, pressurization and depressurization steps of the pressure test become easy to operate.
