Vacuum pumps may occasionally produce alarming detonation sounds, a situation that can leave many vacuum pump users, particularly those with limited experience, feeling overwhelmed and unsure of how to proceed. The sources of these sounds are diverse, making it challenging for even experienced operators to comprehend without proper knowledge. However, with diligent daily maintenance, such special circumstances can be prevented. BTLAS, a manufacturer of vacuum pump accessories, shares the reasons behind the occurrence of these sounds.
- The absence of an intake air filter, a crucial component among vacuum pump accessories, at the vacuum pump’s inlet allows dust in the air to enter the pump and adhere to internal parts, such as valve plates, along with oil mist. Over time, these substances undergo carbonization, forming carbon buildup on surfaces. Under certain conditions, when exposed to flammable gases, this buildup can result in detonation sounds that are released through the exhaust pipe. Both intake and exhaust filters play a significant role in the functioning of vacuum pumps, and vacuum pump users should prioritize their use to prevent numerous potential malfunctions.
- Failure to initiate cooling water circulation before starting the pump can lead to increased temperatures, further promoting carbonization and resultant detonation sounds. Therefore, it is essential to turn on the cooling water supply and ensure the unobstructed flow through the water inlet and outlet before commencing operation.
- Inadequate exhaust can occur when the exhaust port or the vacuum pump accessory, the oil mist separator, becomes blocked. This obstruction can cause gas accumulation, leading to an explosion if the gas cannot be discharged adequately. The oil mist separator is a vital vacuum pump accessory, and its ability to facilitate smooth exhaust and strong pressure release is crucial for pump protection. Thus, the quality of the filter is of utmost importance.
The causes of detonation sounds in vacuum equipment involve factors such as the lack of intake air filters, inadequate cooling before startup, and obstructed exhaust. Regardless of the equipment type, unforeseen situations may arise, some familiar and others unexpected. Operators must adhere strictly to operational procedures, avoiding complacency, and enhance their knowledge base to deepen their understanding of the equipment. Gaining insights into the principles and structures of the devices, as well as familiarity with vacuum pump accessories, enables users to select the most suitable components for their pumps.
