Can I ask for help? What is the function of this hole in the canned pump?
Thread Content
What is the place marked in blue in the picture used for? Is it the venting of the canned pump? If it is venting, do I need to connect a venting line to the gas system? (The operating medium is liquefied gas and naphtha) The following is the pump model
This should be called a maintenance vent, which means that the medium may leak to the coil layer during the clouding process of the equipment. If you dismantle the equipment without venting, it will spurt out (there have been two such accidents with HF acid in our factory).
That is to say, if the pump is running normally, there is no problem if this hole is left open.
If it is a pressure relief hole, during the process of equipment maintenance and pressure relief, isn't the medium leaking into the shielding layer drained out from the leakage point of the shielding layer? What more pressure do you need to relieve?
Can't be eliminated. What you are talking about is that all leaking media with large pores have been cleared. What I am talking about is only small pores like trachoma. At that time, you need to read the instructions to determine whether the hole was a pressure relief hole.
What kind of family does it use a Hermetik pump? . . . I heard that equipment is not expensive and preparation is not expensive, is this true?
Equipment is not expensive, but spare parts are. . . That's what the seniors said
