Help needed regarding the reciprocating oil pressure
Thread Content
This reciprocating machine is a combined unit of a booster and a circulator. Due to a leak in the oil cooler tube bundle earlier, the oil cooler core was replaced, and water was drained after pressurization. After refilling with oil, the oil pump is started; the pressure at the pump outlet can reach 8 to 10 kilograms. After cooling and filtering, the pressure at the lubrication points can be as high as 4.1 kilograms when it’s high, and just over 1 kilogram when it’s low. The outlet pressure can reach 8 to 10 kilograms, regardless of whether it is a high-pressure or low-pressure pump. Besides the filter element, what other factors should be considered as causes of high pressure at the oil pump outlet?
Was the last question from the OP wrong? Or did I misunderstand?
Let’s create a flowchart; saying it this way is too abstract
The pressure at the oil pump outlet is perfectly normal. To address any fluctuations in pressure at the lubrication points, it’s best to check whether there are excessive gaps in the components at those locations
Check the outlet relief valve or safety valve.
