Description

Technical Field

[0001] The utility model relates to the technical field of boiler feed water pumps, in particular to a boiler feed water pump warming pump structure. Background Art

[0002] After the feed pump stops running, the residual water inside the feed pump will gradually cool down and sink to the bottom of the feed pump, while the hotter water will rise to the top of the pump. In this way, there will be a temperature difference between the upper and lower parts of the pump body of the feed pump, which will cause different degrees of thermal expansion in the upper and lower parts of the pump body, causing the internal operating clearance of the boiler feed pump to change, which is not conducive to the safe starting of the feed pump. If the feed pump is started under this circumstance, the moving parts of the feed pump will be seriously damaged, and the dynamic balancing accuracy of the rotor inside the pump body will be destroyed, which will inevitably lead to pump vibration and shorten the service life of the shaft seal.

[0003] For example, the patent document with the announcement number CN 217898286 U discloses a boiler feed water pump forward warm pump system, including: a deaerator water tank, a front pump, a feed water pump, a chemical sampling primary valve, a first warm pump valve, a second warm pump valve, a third warm pump valve, a warm pump connecting mother pipe, etc. The front pump inlet is connected to the deaerator water tank, the front pump outlet is connected to the feed water pump inlet, and the outlet pipe of the feed water pump is provided with a recirculation pipe connected to the deaerator water tank; the deaerator water tank is also provided with a chemical sampling pipe, and the chemical sampling pipe is provided with a chemical sampling primary valve; the recirculation pipe is also connected to the chemical sampling pipe after the chemical sampling primary valve, and the connecting pipe is provided with a first warm pump valve; the recirculation pipe of the standby feed water pump is also connected to the front pump inlet pipe corresponding to other parallel feed water pumps through the warm pump connecting mother pipe, and the connecting pipe is provided with a second warm pump valve and a third warm pump valve in sequence before and after the warm pump connecting mother pipe. The utility model warm pump system is simple, has a small risk of leakage, is easy to operate, and saves energy and reduces consumption.

[0004] However, in actual use, this structure can often only perform simple operations of pumping and mixing cold and hot water from top to bottom inside the boiler. However, the actual mixing range is limited, which will lead to uneven mixing of cold and hot water as a whole. Ultimately, there are still areas of cold and hot stratification inside the boiler. At the same time, the equipment cannot perform more efficient water transfer operations from top to bottom and cannot meet daily use needs. Therefore, it is urgent to design a boiler feed water pump warming pump structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a boiler feed water pump warming pump structure to solve the problem that the existing structure proposed in the above background technology can only perform simple upper and lower cold and hot water pumping and mixing operations inside the boiler during actual use, but the actual mixing range is limited, which will lead to uneven mixing of cold and hot water as a whole. Finally, there are still areas of cold and hot stratification inside the boiler. At the same time, the equipment cannot perform more efficient upper and lower through-water delivery operations and cannot meet daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solutions: a boiler feed water pump warming pump structure, comprising a boiler body, the top end of the boiler body is fixedly connected to a first ring seat, the bottom end of the boiler body is fixedly connected to a second ring seat, and the four sides of the side of the boiler body are fixedly connected to side flow seats;

[0008] Preferably, a filter ring seat is fixedly connected to the surface of the lower pump, and an annular filter element is arranged inside the filter ring seat.

[0009] Preferably, a flow groove is provided inside the lower liquid homogenizing seat, and a liquid homogenizing annular grid is provided on the surface of the lower liquid homogenizing seat.

[0010] Preferably, a lower row of grilles is provided at the bottom end of the inner wall of the first ring seat, and an upper row of grilles is provided at the top end of the inner wall of the second ring seat.

[0011] Preferably, upward one-way valves are arranged on both sides of the first ring seat surface, and downward one-way valves are arranged at both ends of the first ring seat surface.

[0012] Preferably, liquid collecting covers are provided at the upper and lower ends of the interior of the boiler body, and a heat preservation pipe is provided inside the side flow seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The boiler feed water pump warming pump structure can make the equipment perform a more efficient and uniform mixing operation of the cold and hot water inside the boiler through the boiler body, the first ring seat, the second ring seat, the side flow seat, the lower pump machine, the lower row grid, the upper row grid, the liquid collecting hood and the insulation pipe. In actual use, the staff can simultaneously start the lower pump machine and the upper pump machine at the lowest end and the top end of the boiler body, so that they can respectively perform a rapid pumping operation from the two ends inside the boiler body. After that, the water flows along the side flow seats on the four sides of the side of the boiler body and enters the interior of each layer of the first ring seat and the second ring seat respectively, and then passes through the lower row grid and the upper row grid designed on the upper and lower inner walls of the first ring seat and the second ring seat to perform a uniform spraying operation to the central area inside the boiler body. At the same time, the interior of the boiler body can perform a uniform gathering and pressurizing mixing operation of cold water from top to bottom through the design of the liquid collecting hood, thereby improving the overall mixing efficiency of the equipment for the cold and hot water inside the boiler, which reflects the practicality of the equipment design.

[0015] The boiler feed water pump warm pump structure further improves the overall use effect of the equipment through the boiler body, side flow seat, lower liquid uniforming seat, upper liquid uniforming seat, lower pump machine, upper pump machine, annular filter element, flow groove, liquid uniforming annular grid, upward one-way valve and downward one-way valve. In daily use, when cold water is sucked by the lower pump machine and the upper pump machine from the two end positions inside the boiler body respectively, the cold and hot water can first enter the interior of the filter ring seat, and then be filtered by the annular filter element inside the filter ring seat, and then quickly and evenly discharged from the liquid uniforming annular grid of the lower liquid uniforming seat. At this time, the cold and hot water will flow up and down along the insulation pipe inside the side flow seat on the side of the boiler body. At the same time, the upward one-way valve and the downward one-way valve designed on both sides and both ends of the first ring seat can make the cold and hot water move in opposite directions inside the side flow seat, so that they can be more smoothly discharged up and down from the lower grid and the upper grid of the first ring seat, respectively, to improve the flow rate of cold and hot water, which reflects the comprehensiveness of the equipment design.
