Cryogenic liquid pump on sales Do you know what to pay attention to when designing the structure? Let's take a look at it briefly below!
1. In order to ensure uniform cold shrinkage of parts at low temperatures, their structure should be symmetrical;
2. The inlet and outlet pipelines of the pump need to be equipped with cold shrinkage compensation, such as metal bellows compensation, etc.;
3. The connecting parts between the normal temperature zone and the low temperature zone should be made of materials with low thermal conductivity to reduce heat conduction losses;
4. As much as possible to reduce the heat capacity of the parts working in the low temperature zone to reduce the loss of liquid vaporization and shorten the starting time;


5. Cryogenic liquid pump on sales works in the low temperature zone and has relatively moving parts, and choose materials with similar linear expansion coefficients as much as possible; the linear expansion coefficient of the enveloped part must be less than or equal to the line of the enveloped part Expansion coefficient to prevent jamming during cold contraction;
6. For the important parts that work at low temperatures, especially those moving parts with very strict coupling requirements (such as the moving and static rings of the shaft seal, the plunger and the cylinder liner of the plunger pump, etc.), the remaining precision Before processing, it needs to be cold treated. The cold treatment temperature should generally be lower than or equal to the working temperature, and the treatment time is 1 to 4 hours;
7. In order to prevent the vaporization of cryogenic liquids, special attention should be paid to the heat insulation of the pump body and inlet pipes. Generally, pearl sand or foaming materials are used, and vacuum insulation is often used for liquid hydrogen pumps and liquid helium pumps with very low temperature;
The above is a brief introduction to some knowledge that needs to be paid attention to in the structural design of Cryogenic liquid pump on sales.
