Water system for cooling and lubricating pump body

Abstract

The invention discloses a pump body cooling and lubricating water system which comprises a seawater booster pump (1), a closed water inlet door, an industrial water inlet door, a first cooling water door, a second cooling water door, a third cooling water door, a water delivery valve, a water distribution branch, a branch valve and a sealing packing, and relates to the technical field of pump body operation cooling. According to the scheme, after a conventional closed water inlet door pipeline breaks down, the industrial water inlet door can be used for conveying cooling water to the sealing packing, and when the closed water inlet door and the industrial water inlet door both break down and water cannot be conveyed, the industrial water inlet door can be used for conveying cooling water to the sealing packing. Seawater can be guided to the sealing packing through the water distribution branch by the power of the outlet of the seawater booster pump so as to supplement the cooling water gap, so that the phenomena that the packing is burnt and the guide bearing is abraded due to sudden water break of the cooling water can be effectively prevented, and the equipment can operate well and stably.

Description

Technical Field

[0001] The invention relates to the technical field of pump body operation cooling, in particular to a pump body cooling and lubrication water system. Background Art

[0002] Pumps are widely used as medium conveying equipment in factories, mines, urban construction and other industries. In order to maintain the temperature of bearings and shaft seals of pumps, especially large pumps, a circulating cooling water system must be installed. In particular, cooling water is supplied continuously when the pump is in standby state, which makes the system complicated and wastes electricity and water resources.

[0003] Taking the 48LKXD-21X pump as an example, when in operation or standby mode, it needs to continuously supply 4T / H of cooling and lubricating water to the pump body, which is non-recyclable. The annual fresh water consumption is 35,040T, which is equivalent to a cost of 175,200 yuan. In addition, the cooling water supply booster system consumes nearly 200,000 yuan of electricity per year. In addition, the packing seal and rubber guide bearing lubrication cooling water need to maintain a stable water output. Once the cooling water is suddenly cut off, the packing will burn and the guide bearing will wear. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a pump body cooling and lubrication water system, including a seawater booster pump, a closed water inlet gate, an industrial water inlet gate, a first cooling water gate, a second cooling water gate, a third cooling water gate, a water delivery valve, a water distribution branch, a branch valve and a sealing packing: The seawater booster pump is used to provide power for cooling water, the water branch is connected between the seawater booster pump outlet pipeline and the sealing packing, the branch valve is installed on the water branch, the first cooling water gate, the second cooling water gate, the third cooling water gate, the sealing packing and the seawater booster pump are connected through the pipeline, and the water delivery valve is respectively connected to the pipelines of the closed water inlet gate and the industrial water inlet gate.

[0005] Preferably, a pressure gauge is connected to the outlet pipeline of the seawater booster pump.

[0006] Preferably, the closed water inlet gate and the industrial water inlet gate are connected in parallel in the pipeline.

[0007] Preferably, the second cooling water gate and the third cooling water gate are simultaneously connected to the sealing packing.

[0008] Beneficial Effects The present invention provides a pump body cooling and lubrication water system, which has the following beneficial effects: In this case, a multi-branch water supply method is used. When the conventional closed water inlet gate pipeline fails, the industrial water inlet gate can be used to deliver cooling water to the sealing packing. When both the closed water inlet gate and the industrial water inlet gate fail and cannot deliver water, the power of the seawater booster pump's own outlet can guide seawater to the sealing packing through the water branch to supplement the cooling water gap, thereby effectively preventing the packing from burning and the guide bearing from wearing due to sudden cooling water outage, so that the equipment can operate well and stably.

[0010] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0011] See also Figure 1 The present invention provides a technical solution, a pump body cooling and lubrication water system.

[0012] Example: Please see attached Figure 1 In the specific implementation process, a pump body cooling and lubrication water system includes a seawater booster pump 1, a closed water inlet gate 2, an industrial water inlet gate 3, a first cooling water gate 4, a second cooling water gate 5, a third cooling water gate 6, a water delivery valve 7, a water branch 8, a branch valve 9 and a sealing packing 10; The seawater booster pump 1 is used to provide power for cooling water, the water branch 8 is connected between the outlet pipeline of the seawater booster pump 1 and the sealing packing 10, and the branch valve 9 is installed on the water branch 8; In the specific implementation process, a pressure gauge is connected to the outlet pipeline of the seawater booster pump 1 .

[0013] In the specific implementation process, the closed water inlet gate 2 and the industrial water inlet gate 3 are connected in parallel in the pipeline.

[0014] In a specific implementation process, the second cooling water gate 5 and the third cooling water gate 6 are simultaneously connected to the sealing packing 10 .

[0015] The system optimization principle is: During the cooling process of the pump body, the closed cooling water is introduced from the closed water inlet gate 2. During the water supply process, the first cooling water gate 4 is opened, and then the water flows through the second cooling water gate 5 and enters the sealing packing 10 through the cooperation of various water delivery valves 7. The closed cooling water can also be diverted into the pipeline of the industrial water inlet gate 3 through the water delivery valve 7 by control, and then the third cooling water gate 6 is used to provide cooling water for the sealing packing 10 of the seawater booster pump 1. Once the water supply of the industrial water gate and the closed water inlet gate 2 fails and stops supplying water, the branch valve 9 is opened, and the hydraulic pressure at the outlet of the seawater booster pump 1 can transport the seawater back to the sealing packing 10 through the water diversion branch 8 for cooling circulation, thereby compensating for the untimely supply of cooling water at the packing.

[0016] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
