German chiller flat replacement, improve the laser cutting process

Pain point

Laser equipment in the long-term operation process, the laser generator will continue to generate heat resulting in rising temperature, the temperature is too high will affect the normal operation of the laser generator, so the need for water circulation cooling and temperature control, the reason why it is difficult to find the right refrigeration equipment, because the project has the following difficulties:

(1) It is necessary to increase the resin tank in the circulation system to reduce the conductivity; Increase the conductivity detector;

② The water flow rate is 2.5m³/h, the water pressure needs to reach 12-15 kg, and the small flow rate and high pressure frequency conversion pump need to be used;

③ Separate design, the cooling part of the fan is placed outdoors (the ambient temperature is at a minimum of about -30 ° C), and the other parts are placed indoors.

Solution (Select equipment)

Resin tank, small flow, high pressure, split design, three requirements are not common requirements of chiller, AODE through continuous communication with customers, confirm the details of the parameters, understand the problems encountered in the use of customers to issue solutions - [split air cooled chiller], and continue to communicate and confirm the details according to the plan, improve, confirm, and finally reach a consensus.

Enlarge the water tank of the chiller and use internal and external circulation:

A resin tank is added to the inner circulation system to reduce the conductivity, and a conductivity meter is added to monitor the conductivity in water in real time.

High pressure frequency conversion pump is used in the external circulation to achieve the output water flow of 2.5m³/h, and the outlet pressure needs to meet the small flow and high pressure outlet requirements of 12-15kg;

Using PLC control system, using TCP to Internet/ip gateway

At the same time, it is equipped with power supply phase sequence, high and low voltage, motor overload, low liquid level, anti-freeze protection and other safety protection functions

Effect

After the installation and commissioning of the split air cooled chiller at the customer's site, the operation was good, and subsequently A company ordered more equipment. In addition to recognizing AODE's professional design and development capabilities, AODE chiller meets the functions of German chiller, but also can be customized, cost-effective relative to German equipment, while responding quickly and timely rate.
