5. Comprehensive performance of the equipment

5.1 Test Environment:

5.1.1 Power supply: a single station can meet the power demand of 4KW;

5.1.2 Equipment power supply: 1 10A and 16A sockets and reserved terminals for each station, connected to adjustable transformers;

5.1.3 Drain outlet: directly discharged to the floor drain;

5.2 Control: The switch that uses the contactor for power supply, the voltage is set by the adjustable transformer, and the operator manually installs the product

After the product is on the equipment, click the test, automatically open the air control valve, and start the relay to pass the tap water into the instant heat pipe

Electrical, the outlet is equipped with a flow sensor and a temperature sensor to detect whether there is a water flow and the temperature of the water outlet, if not

If there is a water flow, the test will be stopped and alarmed, and the water will be discharged directly, and the test will be automatically stopped when the test time is up, and the alarm will be given.

5.4 Console: Using PLC control, the number of tests and power range are set on the computer, and the interface displays the cumulative number of tests and the current one

information such as operating status;

5.5 Safety protection: The equipment has the functions of leakage and overload protection.

5.6 The equipment is equipped with pure water outlets, and the pure water is supplied by the water supply laboratory, and Party B is responsible for the total pure water point of each laboratory

secondary distribution access to pure water; The high-temperature water after the test is discharged directly to the wastewater pipe and is not recycled.

6. Other Requirements:

6.1 The material of the equipment pipe is made of stainless steel 304 material
