Description

Technical Field

[0001] This invention relates to a performance verification device for a liquid ring vacuum pump, belonging to the field of performance verification equipment for the research and development of liquid ring vacuum pumps. Background Technology

[0002] In the product development process of liquid ring vacuum pumps, prototype manufacturing and performance verification are crucial steps that cannot be avoided. Further refining the obtained test data is an important basis for computer simulation.

[0003] The research and development process requires repeated trial production and verification. This stage mainly aims to correct key geometric dimensions such as impeller profile, eccentricity ratio, and suction / discharge angles. As a key component of the liquid ring vacuum pump, the end cap has multiple functions, including bearing dynamic and static loads and constructing gas-liquid inlet and outlet channels. These diverse functions determine the complex structure of the end cap, making its manufacturing difficult and time-consuming, resulting in significant costs during the trial production phase. However, the end cap is not directly related to the aforementioned key dimensions that need correction. Therefore, repeatedly investing resources and time in the end cap, which does not require verification, actually increases the prototype production cost and slows down the product iteration rate. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a liquid ring vacuum pump performance verification device that can reduce the cost of prototype trial production and improve the product iteration rate.

[0006] The aforementioned drive assembly includes a drive motor, and a coupling is connected to the shaft of the drive motor. The coupling facilitates the connection of the rotor, and the drive motor can drive the rotor with good drive stability.

[0007] The aforementioned linear guide positioning component includes at least two convex slide grooves. The bottom of the moving end cover is fixed with a slider that corresponds one-to-one with the convex slide groove. A positioning component is connected between the slider and the convex slide groove. The directional movement of the moving end cover can be achieved by sliding the slider in the convex slide groove. The positioning component locks the slider and the convex slide groove to achieve the positioning of the moving end cover.

[0008] The aforementioned positioning component is a bolt, which has a simple structure and a good locking and positioning effect.

[0009] The aforementioned locking assembly includes a stationary rib plate on the stationary end cover and a moving rib plate on the moving end cover. A tension rod passes through the stationary rib plate and the moving rib plate, and both ends of the tension rod are threaded with locking nuts. After the rotor is installed between the stationary end cover and the moving end cover, and the pump casing is installed between the two planar distribution plates, the tension rod can lock the stationary end cover and the moving end cover by rotating the locking nuts, thereby ensuring the tightness and sealing of the pump casing. The structure is simple and the operation is convenient.

[0010] The aforementioned stationary end cover and moving end cover are connected to their corresponding flat distribution plates by bolts, which facilitates the disassembly and replacement of the flat distribution plates.

[0011] Working principle and process:

[0012] In use, according to the specifications of the pump developed and verified, the position of the moving end cover is pre-adjusted by the linear guide positioning component. Then, matching planar distribution plates are installed on the stationary end cover and the moving end cover. The corresponding rotor is then installed between the stationary end cover and the moving end cover, and the corresponding pump casing is installed between the two planar distribution plates. The drive end of the rotor is then connected to the drive component to form a simulated pump, and then performance verification can be performed.

[0013] The beneficial effects of this invention compared to the prior art are:

[0014] The liquid ring vacuum pump performance verification device of the present invention is equipped with a stationary end cover and a moving end cover with adjustable spacing. By simply replacing the planar distribution plate of different specifications, it can be used to verify the performance of pumps of different specifications. After all the verification and testing work is completed, the design and manufacturing of the matching end cover can be carried out, which effectively reduces the trial production cost of the prototype and improves the product iteration rate.
