Part five of  LSS— Series Pure water cooling device

8、 Washing  and  trial  running:  Close  the  inlet  and  the  outlet  valves  V21and  V22of  the  ion-exchangers and open all other valves of the pure water loop.Remove the gland of the expansion valve on the top of the water vessel. Open the hose V22 to let the clean tap water flow into the device. When the water has reached the upper part of the level cabinet of the water vessel, close the hose . Alternatively the water may be added through the mouth of the elevated water vessel, close the hose. Alternatively the water may be added through the mouth of the elevated water vessel. Open a little the pressure regulating valve V16    or V17. Switch on the power start the device.Check the direction of rotation of the two pumps. Adjust V16   or V17 gradually to attain the required pressure. Open the vent valves on the external pipe lines and the main equipment pipe lines .Replace the gland into the expansion valve. Inspect the uptightness of the loop. Adjust the electrical and control items . Set the upper and lower alarm limits of the electrical contact temperature and pressure gauges tothe required positions. Allow the device to run for several minutes more. Store is .Then drain water. If the drained water is dirty , Start the device and carry on the washing system several times. Fill again the water vessel with pure water to nearly the ion exchangers with converted and thoroughly mixed anion and action resins in the ratio of 2:1 start the device. Open V22 . Open V21 slowly. When the resistively of the pure water in the loop has risen  gradually  to  the  required  value,  stop  the  device.  Now  the  device  is  ready  for use .Once the valves have been set properly, no adjustment is necessary usually

9、 Operation: Start the device. When all the parts are running normally, put the primary

 equipment into operation. The temperature of pure water will rise gradually. Open the inlet and outlet valves for the secondary water and adjust the flow to keep the temperature of the pure water within the required range. The state of the two pumps (working or spare) is to be exchanged when the working pump has run for about 10 shifts. For this purpose, press the button for the pump to be put into operation and no change of valves is needed.

Ⅴ、Maintenance

 An overall maintenance of all parts is needed after the device has been running for one year.

1、 Heat exchangers: After 1 year’s running, secondary side of heat exchangers will scale in different degree which affects heat-exchange. If pure water temperature increases obviously,dismantling and cleaning of heat exchangers should be carried out. It’s suggested that first dismantling and cleaning should be under the guide of technical attendants of manufacture.

2、 Pumps: CF. the operation instruction for stainless steel water pumps.

3、 Pipelines: Inspect mainly the sealing rubber washers in the flanges for leakage.

4、 Ion exchanger: If the resistivity of the water from the ion exchanger decreases obviously during running, the resin must have become aged. In this case, close the inlet and outlet valves and draw out the resins by means of siphon into 10% NaCl solution. The resins are subjected to type conversion treatment. Then the resins are mixed up and packed into the column. Length of service life of the resins depends on the condition of application and is usually 1 year.

5、 Electric circuit: maintain according to “routine maintenance of control circuit of machine

 tools”. Inspect mainly the sores for looseness, the contact for positioning and burning out and the insulation to the ground. 

6、 If the device is not to be used during freezing seasons, drain off water from the device so

as to avoid pipeline cracking due to freezing.
