High-pressure liquid nitrogen plunger pump

It is recommended to state the relevant questions more clearly, for example: Which components were repaired each time? In the case of severe wear of the copper bushing between the cam and the rod, it is advisable to provide diagrams or photos; otherwise, it will be impossible to understand whether the \"copper bushing between the cam and the rod\" refers to the large-end bushing of the rod or the small-end bushing. ““The fever is very high, but the transmission box doesn’t show an increase in temperature” – Where is it overheating? What’s the specific situation? What does it mean that the transmission case doesn’t heat up?

This situation may be caused by poor fit between the cam and the connecting rod, or insufficient lubrication. 1. Poor fit: If the dimensional fit between the cam and the connecting rod’s copper sleeve is poor, that is, if the sleeve is too large or too small, it will lead to excessive friction and accelerated wear. It is possible to check whether the dimensions of the copper sleeve meet the requirements; if necessary, replace it with a copper sleeve of the appropriate size. 2. Insufficient lubrication: Good lubrication between the cam and the connecting rod is necessary to reduce friction and wear. It is possible to check whether the lubrication system is working properly, including whether there is sufficient lubricant and whether there are any issues such as blockages or leaks. After the maintenance is completed, it is recommended to add an appropriate amount of lubricant between the cam and the connecting rod, and to ensure that the lubrication system is functioning properly. In addition, the following points should also be noted: 3. Increase in the temperature of the transmission box: If the temperature of the transmission box does not rise, it may be due to problems with the transmission mechanism itself, such as friction or poor fit between the components inside the transmission box; it is recommended to conduct inspections and repairs. 4. Motor overload and jamming: Motor overload may be caused by abnormal operation of the infusion valve or blockage in the transmission mechanism. It is possible to check the operation of the infusion valve to ensure it is working properly ； At the same time, check whether there are any blockages or other issues with the transmission mechanism. After the repair is completed, it is recommended to conduct regular inspections and maintenance of this high-pressure liquid nitrogen plunger pump to ensure proper functioning in terms of lubrication and other aspects, thereby preventing similar problems from occurring again. If necessary, you can seek the help of professional repair personnel. .
