Abstract
The utility model relates to a water inlet pipeline system for a water feeding pump of a boiler. The water inlet pipeline system comprises a water inlet pipe communicated with a deaerator, wherein the water inlet pipe is communicated with the water feeding pump, and the diameter of the water inlet pipe is 200mm. After the adoption of the technical scheme, the water inlet pipeline system has the following advantages that the deaerator and the water feeding pump are directly communicated through the water inlet pipe, so the pressure of a water inlet is enhanced, simultaneously, the pipe diameter of the water inlet pipe is enlarged, the water inlet quantity is also favorably increased, the inlet pressure of the water feeding pump is increased, the occurrence of cavitation phenomena is reduced, and the maintenance cost is reduced. The water inlet pipeline system has the advantages that a water feeding mother pipe is omitted on the original basis, the one-to-one connection mode that one deaerator corresponds to one water feeding pump is adopted, the pipe diameter of the water inlet pipe is increased, the reformation cost is low, the maintenance times after the reformation are greatly reduced, and the effect is obvious.
Description
Technical field
The utility model relates to a kind of corollary system of boiler feed pump, relates in particular to a kind of water inlet system of boiler feed pump.
Background technology
As shown in Figure 1, the used boiler feed pump water inlet system of coal chemical enterprise is generally all attend UNICOM's one feed main 2 at oxygen-eliminating device 1 at present; On feed main, connect branch's water inlet pipe 3 again, branch's water inlet pipe 3 and feed pump 4 UNICOMs, branch's water inlet pipe diameter is 125mm, feed main diameter 300mm; Cause inlet pressure on the low side, cavitation phenomenons is comparatively serious, and balancing frame and gimbal wearing and tearing are more serious; Maintenance capacity is big, and expense is high.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of boiler feed pump inlet channel system is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of boiler feed pump inlet channel system comprises the water inlet pipe with oxygen-eliminating device UNICOM, water inlet pipe and feed pump UNICOM.
Above-mentioned boiler feed pump inlet channel system, the diameter of said water inlet pipe is 200mm.
Adopt technique scheme; The utility model has following advantage: oxygen-eliminating device and feed pump are directly used water inlet pipe UNICOM, have strengthened the pressure of water inlet like this, and the caliber of water inlet pipe strengthens simultaneously; Also have to utilize and increase inflow; Derrick the feed pump inlet pressure, reduced the generation of cavitation phenomenons, reduced maintenance cost.The utility model only needs to remove feed main on the original base, and changing an oxygen-eliminating device into is man-to-man connected mode to a feed pump, increases the water inlet pipe caliber, and improvement expenses is low, significantly reduces maintenance frequency after the transformation, and effect is obvious.
Description of drawings
Fig. 1 is traditional feed pump inlet channel system diagram.
The structural representation of Fig. 2 the utility model.
The specific embodiment
As shown in Figure 2 a kind of boiler feed pump inlet channel system comprises the water inlet pipe 5 with oxygen-eliminating device 1 UNICOM, water inlet pipe 5 and feed pump UNICOM, and the diameter of said water inlet pipe 5 is 200mm.Compare with traditional inlet channel system, increased the feed pump inlet pressure, reduced generation and the manpower of cavitation phenomenons, the waste of consumptive material, unwarranted charge has reduced maintenance cost.
Claims (2)
1. boiler feed pump inlet channel system is characterized in that: comprise the water inlet pipe (5) with oxygen-eliminating device (1) UNICOM, water inlet pipe (5) and feed pump UNICOM.
2. boiler feed pump inlet channel according to claim 1 system, it is characterized in that: the diameter of said water inlet pipe (5) is 200mm.
