Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a sealing protective cover for chemical centrifugal pumps. Background Technology

[0002] Sealing guards are suitable for rotating equipment with seals, such as those used in chemical pumps.

[0003] The pressure-bearing capacity of the currently used sealing protective covers is insufficient, and they are easily damaged during actual use, posing a great safety hazard to on-site operations. In addition, most of the currently used sealing protective covers are closed, which makes it impossible for operators to directly observe the internal environment. Furthermore, the sealed pipelines passing through the sealing protective covers make installation, disassembly, and maintenance difficult.

[0004] In view of the problems existing in the above-mentioned existing technologies, it is necessary to research and design a new type of sealing and protective cover for chemical centrifugal pumps, so as to overcome the problems existing in the existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a sealing protective cover for a chemical centrifugal pump, so as to solve the problems existing in the prior art, improve the pressure bearing capacity of the sealing protective cover, facilitate the observation of the internal environment of the protective cover, avoid interference between the sealing pipeline and the sealing protective cover, and facilitate disassembly.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a sealing protective cover for a chemical centrifugal pump, comprising:

[0007] The sealing and protective plate is integrally stamped and formed. The sealing and protective plate has mounting holes, sealing pipe through holes and observation holes. The sealing and protective plate is installed on both sides of the bearing housing. The sealing and protective plate and the bearing housing are detachably connected by screws. The sealing and protective plate has a bending angle.

[0008] The present invention discloses the following technical effects:

[0009] 1. In this device, the sealing and protective plate is fixed to both sides of the bearing housing with screws through the mounting holes, which facilitates installation and disassembly. Through one-piece stamping, the sealing and protective cover fits the bearing housing, which improves the stability of the installation. The stamped steel plate has a certain pressure bearing capacity, which protects the seal and prevents on-site personnel from contacting rotating parts and causing danger.

[0010] 2. In this device, the sealed protective plate is equipped with an observation hole to facilitate operators to observe its internal environment and facilitate maintenance.

[0011] 3. In this device, the sealing protection plate is provided with a through hole for the sealing pipeline, so that the sealing pipeline can be installed on the seal through the sealing protection plate, and the sealing pipeline can be inspected and replaced without disassembly.

[0012] In summary, the technical solution of this utility model solves the problems of exposed rotating parts at the sealing point, insufficient rigidity, poor pressure bearing capacity, difficult disassembly, and inconvenient equipment maintenance in the prior art. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figure 1-3 This utility model provides a sealing protective cover for a chemical centrifugal pump, comprising:

[0021] The sealing protection plate 1 is integrally stamped and formed. The sealing protection plate 1 has mounting holes 3, sealing pipe through holes 2 and observation holes 4. The sealing protection plate 1 is installed on both sides of the bearing housing 6. The sealing protection plate 1 and the bearing housing 6 are detachably connected by screws. The sealing protection plate 1 has a bending angle.

[0022] The sealing protection plate 1 is made by one-piece stamping process. The size of the sealing protection plate 1 is determined by the sealing box where it is placed. The size and position of the sealing pipe through hole 2 are determined by the orientation and size of the sealing interface. The size of the observation hole 3 meets the engineering technical specifications for the safety protection device of rotating equipment. Under the premise of ensuring the safety of on-site personnel, the internal sealing condition can be observed. The sealing protection plate 1 is installed on both sides of the bearing housing 6 with screws. After installation, it does not affect the installation and disassembly of the sealing pipe 5.

[0023] refer to Figure 2 As shown, the sealing and protective plate 1 is integrally stamped and formed into a bent shape with a certain angle, which can play a role in bearing pressure, protecting the seal, and preventing on-site personnel from contacting rotating parts and causing danger.
