Abnormal startup sound of the Bizer compressors
Thread Content
Dear friends: The factory has a set of Bezier screw compression refrigeration units； Host model: HSN7451-60-40P. There is a problem; I would appreciate some guidance from those who are more experienced. Many times, when starting up, there is a loud noise, which returns to normal after about 20–30 seconds. The gasket on one of the end caps of the Bizerba screw compression refrigeration unit (model: HSN7451-60-40P) can sometimes be pushed apart by pressure. (As shown in the photo) When replacing the pad, take a photo of the end cover of the compressed refrigeration unit (upload the photo) ； The gasket of the end cover is always pushed open in the same direction (at the location indicated by the red arrow in the photo). Inside the hole pointed to by the red arrow, there is also a component that can be removed (as shown in the photo) ； I don’t know what component this is either; there are adjustable parts inside. It seems that the pressure of the spring can be adjusted? ? Dear friends, please help analyze and give some advice.
When such things happen, it is the manufacturer who needs to resolve them; it’s not simply a matter of self-repair. Is it a design issue or an installation issue? It’s better to be cautious.
Yes! On the one hand, it is necessary to contact the manufacturer to inquire about the cause of the fault and possible solutions. On the other hand, it is necessary to actively consult various netizens.
It is recommended that the issue cannot be resolved through routine maintenance; this task should be left to the manufacturer for determination. Often, on-site technical issues are not really a problem; what’s more important are the channels for handling things and effective communication.
Performing repairs without understanding the cause is definitely not acceptable; acting rashly without knowing the reasons will surely not work. This machine has had its damaged gaskets replaced and is now back in operation. On the other hand, it’s still necessary to figure out the reason; we can consider countermeasures once the cushion is pushed aside again.
