As vacuum pumps become increasingly widespread, their quality has also improved significantly. Owing to their distinctive advantages, they are now widely used. To help you make the best use of them, let us now explore some methods for extending the service life of vacuum pumps.

Water-ring vacuum pumps offer good performance and are used across many industries. To extend the service life of a vacuum pump, it is essential to regularly check the oil level; if it does not meet the required level, adjust it promptly to ensure compliance. When a water-ring vacuum pump is in operation, the oil level should reach the centre of the oil gauge. The oil change interval should be determined at the user’s discretion, taking into account actual operating conditions and whether performance requirements are being met. Generally, for new vacuum pumps extracting clean, dry gases, it is recommended to change the oil once after approximately 100 hours of operation. Once no black metallic powder is visible in the oil, the oil change interval may be extended appropriately thereafter. Operate the motor in short bursts to check that the rotation direction is correct. Where possible, clear any obstructions from the pipework to ensure the lines remain unobstructed.

Unscrew the priming plug on the vacuum pump housing and fill with priming water. Check the oil condition regularly; if the oil has deteriorated, replace it promptly to ensure the vacuum pump operates normally. Generally, water-ring vacuum pumps should undergo maintenance after 2,000 hours of operation. Check the degree of ageing of the rubber seals, inspect the exhaust valve vanes for cracks, and remove any debris accumulated on the vanes and exhaust valve seats. Clean all components within the vacuum pump chamber, such as the rotor, vanes and springs. Generally, clean with petrol and dry thoroughly. For rubber components, simply wipe dry with a clean cloth after cleaning. Handle all parts with care during disassembly and cleaning to avoid damage. After reassembly, carry out a test run; typically, this involves running the pump dry for 2 hours and changing the oil twice, as volatile substances may remain in the vacuum pump following cleaning. Only resume normal operation once the pump is functioning correctly.

The above outlines methods for extending the service life of vacuum pumps. We encourage you to familiarise yourself with these guidelines.
