Things to learn about High-pressure oil pump

There are two ways of having the necessary power output in most hydraulic applications: high flow at (relatively) low pressure and low flow at high pressure.

Higher pressures mean higher strength and torque from smaller parts is available. And since these elements of displacement are smaller, higher velocities from smaller flows are likely. Smaller flows mean that pipework, pumps, and even the tank can be made smaller-note; 3 to 5 times pump flow/min is the old rule of thumb for tank size (mostly forgotten these days). This is because power is a flow and pressure product; raises pressure, and you can proportionately decrease flow but still have the same power output. One hundred liters/min at 200 bar, for example, equates to the same production of electricity as 50 liters/min at 400 bar.

Your High-pressure oil pump repair service is at the heart of the manufacturing activities, but they are typically the most overlooked machinery in the system once they break down. This is partly because only workers with adequate experience, who are not always available as permanent employees, can conduct some pump repair or maintenance job. Next, the absence of simple servicing, such as operating with a low amount of oil or water in the oil, no or delayed oil adjustments, low pressure due to weakened o-ring of the valve seat, or operating with bent plungers or worn packaging. Your pump can be affected by all these issues.

Second, inlet dire conditions may result in insufficient filtration, dry running, cavitation, premature damage to the packaging and plunger, and valve. Proper servicing of the high-pressure pumps requires adjusting the oil and testing the fluid content discharge devices and consistency. Indeed, daily inspection and servicing of the pump and other components in the system are required to maintain your HP pump.

For the whole system, assemble a regular checklist. Your machine manufacturer and professional installer and service staff will help you build a standard list that involves a detailed visual inspection of all the system's critical parts, such as the compressor, motor or generator, fluid design, filtres, pipe operation, etc. To include the smaller details, any segment should be subdivided.

With the assistance of your technical service staff, build a preventative maintenance plan. Oil changes, valve and packaging changes, belt inspection, and so on can be included. As instructed by the manufacturer, ensure timely pump servicing, usually depending on the hours of service. For example, pump manufacturers prescribe that after 50 hours of use, the first oil change should occur, with additional oil changes happening every 500 hours or three months, or even earlier if the machinery is running in severe conditions.
