Of machinery and equipment, the quality of course important safety precautions in the use of the process, and maintenance, maintenance knowledge is also very important. The following are a few notes mold temperature machine maintenance:
A mold temperature machine external piping requirements
1. Please refer to the following use of temperature piping select the external piping:
Piping quality maximum use temperature of maximum use time
The cotton yarns tube 60 ° C for about six months
Medium pressure hose 120 ° C about a year
Teflon tube 200 ° C about a year
Stainless steel bellows above 200 ℃ about
Note 1. Piping may be due to the use of environmental impact and shorten the service life.
Note 2 oil temperature cooling water pipes do not use a cotton tube, because of the water temperature may exceed 60 ° C, such as the use of cotton yarn tube, pipe rupture easily.
Note 3. Pipe joints can be used at 120 ℃ quick connector, be sure to use a hydraulic connector above this temperature, line pressure, do not use the plug heart and bundle
, Mold temperature heat transfer media selection and replacement
Maximum use temperature recommended replacement time thermal oil Model
The 200 ℃ ESSO500, Mobil 603 and Mobil 605, Japan Sagawa TH320 up to six months to replace
Mobil 605 above 250 ℃ up to six months to replace
Note 1: Thermal oil alternative use, semi-synthetic oil and silicone oil characteristics Do mixed use, mixed use is easy to produce sludge, causing blockage, severe cases will not be able to clear.
Note 2: year replacement clean loop oil from time to time, if the long-term use of more than 150 ℃, as the oil every three to six months, replaced once.
Note 3: Replace the loop oil, careful not to get water or objects have fallen into the tank.
