«Υπερβολικό υγρό επιστροφής:

Όταν ο συμπιεστής λειτουργεί, υπερβολικό ψυκτικό υγρό μεταφέρεται πίσω στον συμπιεστή, το οποίο αραιώνει το λιπαντικό λάδι μέσα στον συμπιεστή, με αποτέλεσμα τη μείωση της συγκέντρωσης του λιπαντικού λαδιού και την αδυναμία εξασφάλισης της κανονικής λίπανσης της επιφάνειας του ρουλεμάν, με αποτέλεσμα τη φθορά.

Η επίστρωση χαλκού βρίσκεται στον κινούμενο κύλινδρο κύλισης και στον κάτω άξονα

Η κάτω επιφάνεια του ρουλεμάν είναι επιχαλκωμένη και το λάδι έχει φθαρεί πολύ

Ανάλυση πιθανής αιτίας:

Η αποσυναρμολόγηση και η δοκιμή βρήκε εμφανή επιμετάλλωση χαλκού στην επιφάνεια των περισσότερων τμημάτων του συμπιεστή.

Υποδεικνύει ότι η περιεκτικότητα σε υγρασία στον συμπιεστή είναι πολύ υψηλή και το νερό θα οξινιστεί με λιπαντικό, ψυκτικό και μέταλλο υπό την επίδραση υψηλής θερμοκρασίας.Η μορφή σχηματισμού οξέος είναι επιμετάλλωση χαλκού, το οξύ θα προκαλέσει ζημιά στα μηχανικά μέρη, οδηγώντας σε φθορά των ρουλεμάν, σοβαρή ζημιά στον κινητήρα θα προκαλέσει ζημιά στην περιέλιξη και καύση

Προτάσεις για προληπτικά μέτρα:

Συνιστάται να επιβεβαιώνεται ο βαθμός κενού του συστήματος και να διασφαλίζεται η ποιότητα και η καθαρότητα του ψυκτικού μέσου, αποφεύγοντας παράλληλα τη μακροχρόνια έκθεση στον αέρα κατά τη συναρμολόγηση και την αντικατάσταση του συμπιεστή.
