I. Overview

?Product Name

Water Hammer Test Bench

?Product Model

DMS-12

?Scope of Application

Widely applicable to whole water purifiers, reverse osmosis water purifiers, filter bottles, and pressure tanks. Generally used for testing the overall pressure resistance performance of water purifier structures.

Detects the maximum pressure that a water purifier can withstand under certain conditions and determines whether the quality of the test piece meets requirements according to relevant standards.

III. Functions and Features

?Main Functions

a)High efficiency, the test device can start frequently under full load;

b)Test pressure, pressure holding time, and other parameters can be set according to test requirements. Equipped with overpressure, overtime, overtemperature, and leakage alarm functions;

c)Automatic collection and processing of test data, automatic establishment of a test database for querying at any time, data can be stored long-term. Real-time display of test curves and parameters, while storing and recording test results such as peak values and test pressure; stored data can be exported in Office document formats. Capable of printing test reports and test pressure curves after completion, with test reports being freely editable.

?Main Features

d)The structural design of the comprehensive water purifier tester adopts a split-type structure, with the overall appearance being coordinated, aesthetically pleasing, and grand.

e)Easy maintenance: output connectors are easy to replace; sensors, pressure gauges, and other components are easy to disassemble and install, facilitating calibration and maintenance; all major components are treated for rust prevention. The working medium is recycled, and the liquid used during testing automatically flows back into the liquid tank.

f)Reliable safety measures:

1)Equipped with emergency pressure relief and safe shutdown functions;

2)Rapid pressure drop after test piece rupture, automatic stop of pressurization, meaning the device has an automatic shutdown protection function after test piece damage, ensuring maximum safety for personnel and equipment, suitable for unattended testing;
