Abstract
A novel pipe arrangement structure for furnace water circulating pump entry. Subcritical and above parameter boilers are generally equipped with boiler water circulating pump equipment, and boiler water circulating pumps are started and stopped more frequently along with the participation of power grid peak shaving in wider depth of a power plant, so that boiler water impurities enter a pump body along with an inlet pipeline of the circulating pump. At present, most of circulating pump inlet pipelines are directly communicated to a circulating pump body from a descending pipe or a water storage tank, and a sewage discharge pipe is not designed in the middle of the circulating pump inlet pipeline, so that impurities can easily enter the pump body from the pipelines. The utility model discloses a constitution includes: t type elbow (2), T type elbow one end and stove water circulating pump inlet pipeline (1) be connected, the other end is connected with collector (4), horizontal pipeline (3) is connected to the mid portion, the collector bottom be connected with hydrophobic pipeline (5), the horizontal pipeline other end and circulating pump body (6) be connected. The utility model particularly relates to a novel pipeline arrangement structure for stove water circulating pump entry.
Description
The technical field is as follows:
the utility model particularly relates to a novel pipeline arrangement structure for stove water circulating pump entry.
Background art:
subcritical and above parameter boilers are generally equipped with boiler water circulating pump equipment, with the participation of power grid peak shaving of wider depth of a power plant, the boiler water circulating pump is started and stopped more frequently, so that boiler water impurities enter a pump body along with an inlet pipeline of the circulating pump, and impurities enter a boiler water pump chamber along gaps due to the fact that certain gaps exist among a pump impeller, a main shaft and a shell. One section of impurity enters into stove water pump cavity, circulates along with cooling water system, no matter is thrust tile or direction bearing all can receive certain damage, and the bearing receives damage back stove water pump operation rotor and produces and rock the volume increase, and the probability that impurity got into the cavity is just big more, finally damages the stove water pump, and the maintenance cycle of circulating pump is not more than two years, and the high maintenance cycle of maintenance cost is long, influences the benefit of power plant. At present, most of circulating pump inlet pipelines are directly communicated to a circulating pump body from a descending pipe or a water storage tank, and a sewage discharge pipe is not designed in the middle of the circulating pump inlet pipeline, so that impurities can easily enter the pump body from the pipelines.
The utility model has the following contents:
the utility model aims at providing a novel pipeline arrangement structure for stove water circulating pump entry avoids impurity to get into the circulating pump body through optimizing this entry pipeline structure.
The above purpose is realized by the following technical scheme:
a novel pipe arrangement structure for a furnace water circulating pump inlet, the composition of which comprises: one end of the T-shaped elbow is connected with an inlet pipeline of the furnace water circulating pump, the other end of the T-shaped elbow is connected with the collector, the middle part of the T-shaped elbow is connected with the horizontal pipeline, the bottom of the collector is connected with the drain pipeline, and the other end of the horizontal pipeline is connected with the circulating pump body.
The novel pipeline arrangement structure for the furnace water circulating pump inlet is characterized in that a furnace water circulating pump inlet pipeline gate valve is installed on the horizontal pipeline, and a drain pipeline primary sewage discharge door and a drain pipeline secondary sewage discharge door are sequentially installed on the drain pipeline.
Has the advantages that:
the utility model discloses an increase T type elbow, collector and horizontal pipeline to set up sewage pipes at the collector cecum, impurity deposit is in collector department, and with entry horizontal pipeline formation horizontal drop, impurity can not flow into the circulating pump body along with medium in the pipeline, and the sewage pipes valve is opened to sedimentary impurity accessible and is discharged. Thereby reduce the probability that the pump body damaged through reducing the probability that impurity got into the circulating pump body, extension circulating pump life cycle reduces the maintenance cost when improving the utilization ratio, can effectively reduce impurity and get into the circulating pump and do not influence normal use, the maintenance of circulating pump.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
in the figure: 1. furnace water circulating pump inlet pipeline, 2, T type elbow, 3, horizontal pipeline, 4, collector, 5, hydrophobic pipeline, 6, circulating pump body, 7, furnace water circulating pump inlet pipeline gate valve, 8, hydrophobic pipeline blowdown primary door, 9, hydrophobic pipeline blowdown secondary door.
The specific implementation mode is as follows:
example 1:
a novel pipe arrangement structure for a furnace water circulating pump inlet, the composition of which comprises: t type elbow 2, T type elbow one end and stove water circulating pump inlet pipeline 1 be connected, the other end and collector 4 are connected, horizontal pipeline 3 is connected to the mid portion, the collector bottom be connected with hydrophobic pipeline 5, the horizontal pipeline other end and circulating pump body 6 be connected.
Example 2:
according to embodiment 1 a novel pipe arrangement structure for furnace water circulating pump entry, horizontal pipeline on install furnace water circulating pump entry pipeline gate valve 7, hydrophobic pipeline on install hydrophobic pipeline blowdown primary door 8 and hydrophobic pipeline blowdown secondary door 9 in proper order.
