Description

Technical Field

[0001] The utility model relates to the technical field of water delivery systems, in particular to a shock-absorbing water delivery system with a high-pressure pump. Background Art

[0002] In the water delivery system of a concentrator, a high-pressure pump is mostly used for transportation, and the high-pressure pump is connected to an inlet water pump sump. Due to poor assembly, bearing lubrication, motor failure, impeller eccentricity, cavitation, etc. of the high-pressure pump, the high-pressure pump will vibrate during operation, causing damage to the motor, pipeline, inlet valve and pump sump foundation. In order to eliminate the influence caused by the vibration of the high-pressure pump during operation, a corrugated pipe is often installed on the inlet pipeline for vibration reduction. In actual use, the corrugated pipe will affect the flow rate and resistance of the fluid to a certain extent, thereby affecting the performance of the pump. At the same time, the corrugated pipe generally cannot meet the requirements of large flow rate and high pressure working conditions, and the failure rate is relatively high. In addition, when replacing equipment in a large pipeline, the pipe-to-pipe distance is fixed, and the flange can only be restored by cutting and welding, which brings a great deal of workload. Therefore, it is necessary to improve and eliminate the influence caused by the vibration of the high-pressure pump during operation and the problem of large workload in replacing equipment in a large pipeline.

[0003] Therefore, there is a need for improvement in the shock-absorbing water delivery system with a high-pressure pump in the prior art. Summary of the Utility Model

[0004] In view of this, the purpose of the embodiment of the present utility model is to provide a shock-absorbing water delivery system with a high-pressure pump, which eliminates equipment damage caused by vibration during the operation of the high-pressure pump by optimizing the connection structure, and solves the faults caused by the vibration of the high-pressure water pump.

[0025] In addition, the mention of "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this utility model. The occurrence of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0026] The water conveyance system of a beneficiation plant is a complex and important system, and its structure and function need to be designed and optimized according to the actual needs of the beneficiation plant. Based on the problems existing in the prior art, for the connection method between a high-pressure water pump and a pump sump described in this utility model, a steel-rubber expansion joint is used to connect the inlet pump sump and the high-pressure water pump. Since the steel-rubber expansion joint has strong shock absorption in both the longitudinal and transverse directions, it can effectively isolate the vibration source equipment, prevent vibration transmission, avoid resonance, and effectively eliminate equipment damage caused by vibration during the operation of the high-pressure pump, thus solving the faults caused by the vibration of the high-pressure water pump. In addition, the number of expansion joints can be increased or decreased according to the on-site needs, which provides great convenience for on-site operations.

[0027] As Figure 1Shown is a shock-absorbing water delivery system with a high-pressure pump provided by the present utility model, including: a high-pressure pump 1, an expansion joint 3, and a pump sump 5 that are sequentially connected through pipelines. The expansion joint 3 is telescopable in the horizontal direction, and adapters are provided at both ends of the expansion joint 3 to fasten the pipelines. Since the expansion joint has strong shock-absorbing effects both longitudinally and laterally, it can effectively isolate the vibration source equipment, prevent vibration transmission, avoid resonance, and effectively eliminate equipment damage caused by the vibration during the operation of the high-pressure pump, solving the faults caused by the vibration of the high-pressure water pump. In addition, the number of expansion joints can be increased or decreased according to the on-site needs to effectively reduce and increase the pipe distance, providing great convenience for on-site operations.

[0028] The design of the expansion joint allows the pipeline to undergo certain telescopic deformations when affected by factors such as temperature and pressure. Such deformations can be axial, lateral, or angular. The expansion joint can compensate for these deformations, preventing the pipeline from rupturing due to excessive stress or the loosening of connections. Therefore, introducing an expansion joint in the water delivery system exhibits strong shock-absorbing effects both longitudinally and laterally. For longitudinal shock absorption, the expansion joint can effectively absorb and disperse the longitudinal vibrations generated by the high-pressure pump. Such vibrations may be caused by the operation of the pump, the impact of the fluid, or pressure fluctuations within the system. The longitudinal shock-absorbing effect of the expansion joint can significantly reduce the damage of these vibrations to the pipeline and connected equipment, thereby extending the service life of the equipment. In addition, for lateral shock absorption, similarly, the expansion joint can effectively handle lateral vibrations. Such vibrations may come from the bending of the pipeline, installation errors, or external environmental interference. The lateral shock-absorbing effect of the expansion joint can reduce the lateral displacement and distortion of the pipeline, maintaining the stability and reliability of the pipeline.

[0029] Further, the expansion joint is a steel corrugated expansion joint. The steel corrugated expansion joint has excellent telescopic properties and can expand and contract accordingly according to the thermal expansion and contraction of the pipeline, avoiding excessive stress on the pipeline and thus effectively preventing the pipeline from rupturing.

[0030] In some embodiments, the expansion joint includes an outer pipe and an inner pipe. The outer pipe and the inner pipe are slidably connected, and the telescopic deformation is resisted through the slidable sleeve connection. Specifically, one or more slidable sleeves are usually installed between the outer pipe and the inner pipe of the expansion joint. These sleeves are designed with precise sliding mechanisms, allowing the inner pipe to smoothly move axially within the outer pipe. When the pipeline system is affected by temperature changes, pressure fluctuations, or other external forces, the inner pipe will expand and contract within the outer pipe according to the actual situation, thereby absorbing or releasing the stress and deformation in the pipeline system. This slidable connection method of the expansion joint brings significant beneficial effects. First, it can effectively prevent the stress and deformation generated by the pipeline system due to temperature changes or pressure fluctuations, protecting the pipeline and its connection components from damage. This is crucial for ensuring the long-term stable operation of the pipeline system. Those skilled in the art can select a steel corrugated expansion joint or an expansion joint with a sliding sleeve according to actual needs.

[0031] Further, a sealing ring is provided inside the adapter. The sealing washer can not only ensure the sealing performance, but also provide a certain shock-absorbing and buffering effect. When the pipeline or equipment is vibrated or impacted, the washer can absorb part of the impact force, reduce the damage to the connecting parts or the system, and protect the equipment from damage.

[0032] Further, an electric gate valve 2 is provided between the high-pressure pump 1 and the expansion joint 3. A water level gauge is provided in the pump sump 5, and the water level gauge is electrically connected to the electric gate valve 2 to alarm the designed threshold of the water level gauge. When the preset water level is exceeded, the electric gate valve 2 automatically closes.

[0033] Further, a manual gate valve 4 is provided between the expansion joint 3 and the pump sump 5.

[0034] Further, the adapter is a flange, which is connected to the pipeline through the flange. As a key component for connecting pipelines, the flange is exquisitely designed and practical. The flange usually has two parallel flange faces with bolt holes, and these two flange faces can be connected to each other through fasteners such as bolts, nuts and gaskets. Since the diameter of the flange can be adjusted as needed, they can easily match pipelines with different diameters. In some embodiments, different flanges can be replaced according to the pipeline size to adapt to pipelines with different diameters.

[0035] Further, the high-pressure water pump mainly consists of a pump body, a pump shaft, an impeller, a sealing device, inlet and outlet pipelines, etc. The pump body is the main part of the high-pressure water pump, usually made of metal or engineering plastics, with good corrosion resistance and pressure-bearing capacity. The pump shaft is a component connecting the motor and the rotor, and bears the functions of transmitting torque and axial force. The impeller is the rotor component of the high-pressure water pump, usually composed of multiple blades, and is used to generate high-speed flowing liquid. The sealing device is used to ensure the sealing performance inside the pump body and prevent liquid leakage. However, during the operation of the high-pressure water pump, due to poor assembly, bearing lubrication, motor failure, impeller eccentricity, cavitation, etc., the high-pressure pump will vibrate during operation, causing damage to the motor, pipeline, inlet valve and the pump sump foundation.

[0036] Further, the shock-absorbing water delivery system with a high-pressure pump may further include a controller that can be connected to the electric gate valve 2 to control the opening and closing of the electric gate valve 2.

[0037] The usage method of the shock-absorbing water conveyance system with a high-pressure pump of the present utility model is as follows: Turn on the high-pressure pump 1, the electric gate valve 2 and the manual gate valve 4, and convey water into the pump sump 5 through the pipeline. During the water conveyance process, the expansion joint 3 can expand and contract in the pipeline direction to absorb and disperse the vibration generated by the high-pressure pump 1. When the water volume in the pump sump 5 is too large, the manual gate valve 4 can be manually adjusted to control the water speed. In addition, the water level gauge in the pump sump 5 can also be linked with the electric gate valve 2 through the controller to set a water level threshold, and when the threshold is reached, the electric gate valve 2 will be automatically shut down.

[0038] The present utility model provides a shock-absorbing water conveyance system, which uses expansion joints to connect the inlet pump sump and the high-pressure water pump, eliminates equipment damage caused by vibration during the operation of the high-pressure pump, and solves the faults caused by the vibration of the high-pressure water pump. In addition, the number of expansion joints can be increased or decreased according to the on-site needs to effectively reduce and increase the pipe distance, which provides great convenience for on-site operations.
