1Automatic intelligent control cooling circulating water tankProduct Introduction

The automatic temperature control cooling water circulation device is specifically designed for instruments that require water circulation cooling protection. For example:ICPEmission spectrometer,ICPMass spectrometers, graphite furnace atomic absorption spectrometers, and other instruments that require circulating cooling water for heat dissipation. This device has the characteristics of low noise, cooling capacity, and wide temperature control range, and is equipped with wheels for easy transportation. It is composed of automatic temperature control intelligent instruments, high-efficiency plate heat exchangers, Italian imported adjustable pressure high-pressure pumps, and environmentally friendly energy-saving refrigeration and cooling systems. The main parameters of the circulating cooling water device are shown in the following table:

1. Installation method

After unpacking, place it in a horizontal position and check if the relevant components are damaged. Correctly connecting the outlet and return water means connecting the outlet of the circulating cooling water device to the inlet of the refrigeration equipment, and connecting the outlet of the refrigeration equipment to the return water of the circulating cooling water device. Open the top cover of the water injection hole, inject deionized water, fill up with water, about20Raise. Plug in the power and turn on the power of the cooling water circulation device. The temperature display instrument light will turn on, showing the current water temperature. The water pump will start, and the pressure gauge on the panel will display the current water pressure. The water flow will begin to circulate. Observe whether there is any water leakage at the valve and pipe joints.

4matters needing attention

1 The cooling water circulation device must have a reliable grounding, and the ground wire should be connected to the grounding device of the building.

2 Ensure that this device does not tilt during transportation and handling, and tilting is not allowed to exceed45The degree cannot be reversed.

3 After adding water to the water tank, open the outlet valve to ensure smooth water flow before connecting the instrument. Turn on the power of the water pump to operate it.

4 When the temperature sensing probe is short circuited or disconnected (including not properly connected to the host), the thermostat enters an alarm state and the buzzer sounds,LEDDisplay“Er”And flicker. Pressing any key at this time will eliminate the alarm sound. If the button is not pressed, the alarm will continue until the fault is resolved.

5 When the temperature limit alarm value is exceeded, the thermostat will sound an alarm and the buzzer will beep,LEDFlashing, press any key to eliminate the alarm. If not pressed, the alarm will continue until the temperature returns to the range.

6 After this device is powered on, there is a delay3The compressor will start in minutes before entering the production process|Cold state; MachineWhen powered on, the interval between the two suction actions of the refrigeration relay is ≥3minute.
