Description

Technical Field

[0001] The utility model relates to the technical field of machine pump fault monitoring, in particular to a slurry pump vibration fault monitoring device. Background Art

[0002] Slurry pumps are important equipment in mining production, and their operating status directly affects the production efficiency and safety of the mine. However, since slurry pumps work under high load and harsh environment for a long time, various faults are prone to occur, such as bearing wear, imbalance, looseness, etc. These faults often cause abnormal vibration of the slurry pump, which in turn affects the normal operation of the equipment.

[0003] In the prior art, a vibration analyzer is usually used to monitor and analyze the vibration failure of a slurry pump in order to diagnose the cause of the failure of the slurry pump. During monitoring, the vibration sensor on the vibration analyzer is magnetically fixed to the slurry pump, and the vibration data is transmitted to the vibration analyzer through the vibration sensor, and the vibration analyzer analyzes the vibration data. However, the vibration analyzer usually uses a single vibration sensor for monitoring, and can only monitor the vibration at a certain point in the slurry pump. The monitoring range is small, the vibration monitoring is not comprehensive enough, the accuracy is not high enough, and it is impossible to fully reflect the vibration state of the slurry pump. Therefore, it is particularly important to develop a monitoring device that can monitor the vibration failure of a slurry pump at multiple points and is easy to install and connect.

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] like Figures 1 to 4As shown, a slurry pump vibration fault monitoring device includes multiple groups of fixed plates 3 and multiple groups of vibration sensors 5. The multiple groups of fixed plates 3 are arranged in a horizontal interval structure. The adjacent fixed plates 3 are fixedly connected by two groups of corrugated connecting pipes 4 made of stainless steel. Each of the multiple groups of fixed plates 3 is equipped with a group of vibration sensors 5. A bottom plate 11 is arranged at intervals on the upper side of the middle group of fixed plates 3. The bottom plate 11 is fixedly connected to the fixed plate 3 through multiple groups of supporting uprights 10. A cable transfer box 12 is fixedly installed on the bottom plate 11. The multiple groups of vibration sensors 5 are connected to the cable transfer box 12 through a data transmission line 2. The data transmission line 2 is connected to the vibration analyzer 1 from the output end of the cable transfer box 12. This design solves the problem that the existing vibration analyzer 1 usually uses a single vibration sensor 5 for monitoring, can only monitor the vibration at a certain point in the slurry pump, has a small monitoring range, is not comprehensive enough in vibration monitoring, is not accurate enough, and cannot fully reflect the vibration state of the slurry pump.

[0026] A placement rack 13 with a flat S-shaped structure is fixedly arranged on the upper side of the bottom plate 11, and the vibration analyzer 1 is placed on the placement rack 13. The placement rack 13 can support the vibration analyzer 1, and is convenient for placing the vibration analyzer 1. At the same time, the S-shaped structure can firmly clamp the vibration analyzer 1, and ensure the stability of the vibration analyzer 1.

[0027] A rubber sheath 9 is sleeved on the annular surface of the corrugated connecting pipe 4 . The rubber sheath 9 provides protection for the corrugated connecting pipe 4 , plays an anti-corrosion and wear-resistant role, and can reduce the wear of the corrugated connecting pipe 4 .

[0028] The vibration sensor 5 passes through the fixing plate 3, and its lower end extends out from the fixing plate 3. The vibration sensor 5 is fixed to the fixing plate 3 by two sets of nuts. This design can ensure the installation stability of the vibration sensor 5 through the two sets of nuts, and prevent the vibration sensor 5 from loosening due to the vibration of the slurry pump during monitoring. The use of nuts to fix the vibration sensor 5 is also convenient for fine-tuning or replacement.

[0029] A support platform 7 is fixedly provided at the bottom of the left and right fixed plates 3 near the outer edges. The support platform 7 can support the entire device from both sides, making the device more stable when placed. A layer of magnet 8 is fixedly connected to the bottom of the support platform 7, and the lower surface of the magnet 8 is flush with the lower end surface of the vibration sensor 5. The set magnet 8 further enhances the stability of the device. The magnet 8 tightly adsorbs the device on the slurry pump through magnetic force, effectively preventing the device from moving or slipping during operation, and at the same time facilitates the installation and disassembly of the device, thereby improving the convenience of operation.

[0030] A set of C-shaped handles 6 are fixed on the upper side of the left and right fixing plates 3, and the surface of the handles 6 is covered with rubber pads. The handles 6 provide convenient force points for the installation of the device, making it easy to install the device on the slurry pump. The rubber pads on the surface of the handles 6 greatly increase the comfort of holding. The rubber material is soft and has a certain anti-slip performance. Even in a wet or oily working environment, it can provide a stable grip and reduce hand discomfort.

[0031] The working principle of the vibration fault monitoring device for a slurry pump is as follows: in actual use, firstly, multiple groups of vibration sensors 5 are fixedly installed on the fixed plates 3 at different positions through nuts, and the vibration sensors 5 are connected to the cable adapter box 12 through the data transmission line 2. Then, the two groups of handles 6 are held by both hands, and the device is placed on the upper side of the monitoring part of the slurry pump, so that the vibration sensor 5 on the middle fixed plate 3 is adsorbed to the slurry pump through its own magnetism. Then, force is applied to the handle 6 to press the fixed plates 3 on both sides downward. The corrugated connecting pipe 4 between different fixed plates 3 is bent downward by force, so that the device is in an arc shape as a whole. When the fixed plates 3 on both sides are close to the slurry pump, the magnets 8 thereon are fixed on the surface of the slurry pump through magnetic adsorption, and then the device is fixedly connected to the slurry pump as a whole. Then, the cable adapter box 12 is connected to the vibration analyzer 1 through the data transmission line 2, and the vibration of the slurry pump is analyzed by the vibration analyzer 1. The operator can hold the vibration analyzer to observe the vibration situation, or place the vibration analyzer 1 on the placement rack 13 to free his hands. The multiple groups of vibration sensors 5 can be used to monitor different positions of the slurry pump, thereby improving the comprehensiveness of the monitoring.

[0032] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
