siphon tank
Thread Content
On the low-temperature methanol washing units, there are siphon tanks mounted on top of the pumps; these tanks contain systems for methanol circulation and water circulation. Want to know the function of a siphon tank? And I heard from the experienced workers that methanol in the siphon tank can be used to clean the mechanical seal; if the mechanical seal is cleaned, does the waste methanol resulting from that cleaning process still circulate within the siphon tank? Will it have no impact?
The flushing scheme for your pump is generally 11+52+62; the 52 refers to the two pipelines connected to the siphon tank (liquid storage tank). There is a pumping ring inside the mechanical seal, and the methanol in the secondary sealing chamber circulates due to thermal siphoning and pumping effects. This liquid is used solely for lubricating and cooling the seal. It will not affect usage
Is a flushing scheme like this established by experience and convention, or is it determined by consulting some references?
Based on practical experience, it’s generally the case that the flushing plan is determined by the effectiveness of its use. No matter how good a flushing plan may be, if it isn’t suitable for my specific working conditions, then it’s not an appropriate choice
So, for example, you’re talking about a desalination water pump with a flow rate of 100 and a head of 120. Should we choose plan01 1CW-FX?
PLAN01 is a custom-sealed chamber that requires a slanted hole to be drilled in the pump cover. PLAN11 is the default single-sided rinsing scheme.
The siphon tank is used in Plan52, primarily serving as a second seal after PL1N11; it can be used to flush, cool, and lubricate the mechanical seal. Secondly, the use of PLAN52 allows it to be determined whether there is a leak in PLAN11; harmful substances such as methanol must not enter the working environment, and therefore the presence of a siphon tank enables it to check for leaks in PLAN11 by monitoring the liquid level
