概要： The manufacturer of liquid-ring vacuum pumps says that these pumps have a wide range of applications, so it’s essential to understand the operational precautions before using them. Only by doing so can you make better use of them. If you’re interested in this topic, let’s take a closer look together—it might be helpful for those who are involved. The manufacturer of liquid-ring vacuum pumps points out that these pumps are widely used across various industries, making their broad application all the more important. In fact, the specific type of liquid-ring vacuum pump is primarily determined by the medium being pumped, the required gas flow rate, the desired vacuum level, or the exhaust pressure. When using a liquid-ring vacuum pump, it’s crucial to ensure that the selected pump’s vacuum level is as high as possible—that is, the pump should operate within its critical zone, where the required vacuum level or critical exhaust pressure is achieved. Only under these conditions can the vacuum pump function properly and meet the intended requirements. Avoid operating the vacuum pump near its maximum vacuum or exhaust pressure range. Operating in this region not only results in extremely low efficiency but also makes the pump highly unstable; sometimes, it can easily cause vibrations and noise. When a liquid-ring vacuum pump with a high vacuum level operates in this region, cavitation often occurs. An obvious sign of cavitation is the noise and vibration generated inside the pump. Excessive cavitation can damage components such as the pump body and impeller, eventually rendering the vacuum pump unusable.

The manufacturer of liquid-ring vacuum pumps states that these pumps are widely used across various industries, making their extensive application essential. In fact, the specific type of liquid-ring vacuum pump is primarily determined by the medium being pumped, the required gas flow rate for operation, the desired degree of vacuum, or the exhaust pressure. When using a liquid-ring vacuum pump, it’s crucial to ensure that the selected pump achieves the highest possible vacuum level—that is, to operate within the critical zone defined by the required vacuum or critical exhaust pressure. Only under such conditions can the vacuum pump function properly and meet the intended operational requirements. Avoid operating the vacuum pump near its maximum vacuum or exhaust pressure limits. Operating in this range not only results in extremely low efficiency but also leads to significant instability, sometimes causing vibrations and noise in the pump. Moreover, when high-vacuum liquid-ring vacuum pumps operate in this region, cavitation frequently occurs. An obvious sign of cavitation is the noise and vibration generated within the pump. Excessive cavitation can damage components such as the pump casing and impeller, ultimately rendering the vacuum pump incapable of performing its intended function.
The manufacturer of liquid-ring vacuum pumps points out that, of course, insufficient vacuum performance can occur during operation. The causes of this issue include: first, checking whether the supply voltage is within the motor’s rated voltage range; second, increasing the water supply (but keeping it within the proper range—otherwise, the motor may become overloaded and overheat); third, adjusting the clearance between the impeller and the distribution plate (typically 0.15–0.20 mm); fourth, replacing the mechanical seal; fifth, replacing the impeller; and sixth, inspecting the piping at the outlet. In addition, we recommend that you carefully select the appropriate vacuum pump based on the system’s required pumping capacity. When choosing the type of vacuum pump or vacuum unit, be sure to select the correct model according to the system’s required pumping rate. (For details on selecting the pumping capacity of vacuum equipment and calculating the vacuum time, please refer to our company’s product specifications.) It is essential to connect a cold trap upstream of the liquid-ring vacuum pump. The water in the circulating pump should be changed regularly to prevent residual solvents from being ignited by sparks from the motor. Before use, the distillate should be cooled, then slowly vented until equilibrium is reached before shutting down. Alternatively, pay attention to frequently changing the oil in the pump. A rubber hose should be connected to the exhaust port and routed to a fume hood.
