What are the solutions for smoking and oil spraying in vacuum pumps?


Information Summary:

1. Smoking: If smoking occurs right after the pump is first started up, this is normal. However, if smoking persists for an extended period, it’s abnormal. The solution: Smoking indicates that there’s a repair or leak somewhere outside the pump’s intake port—such as in the pipelines, valves, or containers. Once the leaks are located and repaired, the smoking will stop. 2. Oil喷射: This indicates numerous leaks outside the intake port, possibly even with the intake port directly exposed to the atmosphere. The solution: Seal the pump’s intake port and run the pump. If no oil is sprayed, it means there’s a leak. Alternatively, the exhaust valve flap may be damaged; check whether the exhaust valve flap is broken and replace any damaged flaps.

  1. If smoke is observed shortly after the pump starts up, this is normal. However, if smoke persists for an extended period, it’s abnormal. The solution: Smoke indicates that there’s a repair or leak somewhere outside the pump’s intake—specifically in the pipes, valves, or containers. Once the leaks are identified and repaired, the smoking will stop.

  2. If oil is not being injected, it indicates that there are significant leaks around the intake port—or even that the intake port is exposed directly to the atmosphere. The solution: Seal the pump’s intake port and run the pump. If no oil is injected, this confirms the presence of leaks. Alternatively, the exhaust valve flap may be damaged; check whether the exhaust valve flap is damaged and replace any defective flaps.

Liquid Ring Vacuum Pump: Principle, Applications, and Analysis of Advantages and Disadvantages As an important industrial equipment, the liquid ring vacuum pump plays a pivotal role in industrial production thanks to its unique working principle and wide range of applications. This article provides a detailed analysis and discussion of the working principle, application fields, as well as the advantages and disadvantages of the liquid ring vacuum pump. I. Working Principle of the Liquid Ring Vacuum Pump The working principle of the liquid ring vacuum pump is based on its distinctive structural design. The pump housing contains an eccentric rotor equipped with fixed blades. As the rotor rotates within the pump housing, water (or other liquid) is thrown outward toward the stator wall, forming a liquid ring that is concentric with the stator. Together with the rotor blades, this liquid ring creates a variable-volume rotary positive-displacement vacuum pump. As the rotor spins, the volume of the pump chamber undergoes periodic changes, enabling the processes of suction, compression, and exhaust. II. Application Fields of the Liquid Ring Vacuum Pump The liquid ring vacuum pump is widely used in various industrial production processes, particularly in applications that require dust-free and sterile environments. For example, in the power industry, it is employed in processes such as condenser vacuum generation, vacuum-assisted water extraction, and flue gas desulfurization. In the petrochemical industry, it is utilized for gas recovery, gas emission control, and reduced-pressure distillation of crude oil. In the paper-making industry, the liquid ring vacuum pump is used for processes including coarse pulp washing, lime slurry filtration, and vacuum dewatering.

Liquid-ring vacuum pump: Principle, applications, and characteristics. In industrial production, vacuum pumps are common equipment with wide-ranging applications across multiple fields. Among them, the liquid-ring vacuum pump, with its unique structure and operating principle, plays an important role in various process operations. This article will provide a detailed introduction to the principle, applications, and characteristics of the liquid-ring vacuum pump. I. Working Principle of the Liquid-Ring Vacuum Pump As the name suggests, the liquid-ring vacuum pump uses water as the working medium and achieves the processes of suction and exhaust by continuously changing the volume within the liquid ring. Inside the pump body, there is an eccentric rotor. As the rotor rotates, it flings water (or other liquid) toward the stator wall, forming a liquid ring that is concentric with the stator. Together with the rotor blades, this liquid ring creates a rotary variable-volume vacuum pump. As the rotor spins, the volume of the liquid ring changes continuously, thereby enabling the processes of suction, compression, and exhaust. Specifically, when the rotor blades rotate to the suction port, the gas inside the pump body is drawn in and mixed with water, forming a gas-liquid mixture. As the rotor continues to rotate, the gas-liquid mixture is pushed toward the exhaust port and compressed in the process. When the mixture reaches the exhaust port, the gas is discharged from the pump, while the water returns to the interior of the pump, thus completing a continuous working cycle. II. Liquid-Ring Vacuum…
