Abstract
A cooling water circulation mechanism of a high pressure seal packing of a slurry pump comprises an water inlet header pipe, a water inlet valve, an water outlet valve, a water tank and a water pipe. The utility model is characterized in that a loop of the water inlet header pipe is connected with the header pipe through a by-pass valve, the other loop of the water inlet header pipe is connected with the water tank through a water inlet valve and a water inlet pipe, the exit of the water tank is connected in series with a water inlet valve, an inline pump and a water outlet valve, the water outlet valve is connected with the header pipe, the header pipe is connected in parallel with shaft sealing of each of slurry pump and the bearing cooling water pipe, the bearing cooling water pipe is connected with a backwater header pipe, the other end of the backwater header pipe is connected with the water tank, the water in the shaft sealing enters into the pump body, after has worked in the bearing cooling water pipe, the water enters into the backwater header pipe and is recovered to the water tank and then reused after cooled and filtered. The cooling water circulation mechanism of a high pressure seal packing of a slurry pump of the utility model changes the cooling water circulation mechanism of a high pressure seal packing of a slurry pump to significantly reduce labor intensity, save energy while recycle the cooling water.
Description
Technical field
The utility model relates to a kind of ash pump, especially a kind of ash pump high pressure shaft seal cooling water cycling mechanism.
Background technique
Ash pump is the important component part of boiler slag removal system, belong to the horizontal single swing arm type centrifugal pump of PH type series, specified outlet pressure is 0.6MPa, the most scabrous problem is the ash pump undercapacity in the use, it has seriously restricted the normal operation of main explained hereafter, below the concrete manifestation: 1, have a strong impact on the ability of gathering dust of boiler, cause most flue dust to be discharged in the atmosphere, cause environmental pollution; 2, serious to boiler induced-draft fan infringement, because the ability of gathering dust reduces, a large amount of moisture content enter in the induced draught fan, cause the induced draught fan Oscillation Amplitude big, and sudden strong, and are serious to the infringement of induced draught fan body, and recondition expense height, difficulty are big; 3, reduce the deslagging ability of boiler, the slag of boiler is to enter slag runner after handling, and with flushing cinder water it is entered slag bath again, if flushing cinder water pressure deficiency will cause slag runner to stop up, influences environmental hygiene, and boiler is forced to stop production.
Summary of the invention
The purpose of this utility model just provides and a kind ofly can satisfy the production needs, can increase work efficiency again, the ash pump high pressure shaft seal cooling water cycling mechanism of energy saving.
Ash pump high pressure shaft seal cooling water cycling mechanism of the present utility model comprises water inlet manifold, inlet valve, outlet valve, water tank and water pipe, house steward is inserted through bypass valve in a loop that is characterized in water inlet manifold, inlet valve is passed through in another of water inlet manifold loop, intake pipe links to each other with water tank, be connected in series inlet valve in the outlet of water tank, pipeline mounted pump and outlet valve, outlet valve inserts house steward, house steward's axle envelope and bearing cooling water pipe that inserts each ash pump in parallel, the bearing cooling water pipe links to each other with the return main, return main's the other end inserts in the water tank, water in the axle envelope enters in the pump housing, and the water in the bearing cooling water pipe is finished and entered the return main after the merit and be recycled to water tank through utilizing again behind the cold filtration.
Ash pump high pressure shaft seal cooling water circulator of the present utility model can reduce labor intensity greatly by changing pulp pump high pressure shaft seal cooling water cycling mechanism, and energy saving has realized the recycling of cooling water simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of ash pump high pressure shaft seal cooling water cycling mechanism comprises water inlet manifold 1, inlet valve, outlet valve, water tank 4 and water pipe, house steward 11 is inserted through bypass valve 8 in a loop that is characterized in water inlet manifold 1, another loop of water inlet manifold 1 is by inlet valve 2, intake pipe 3 links to each other with water tank 4, serial connection inlet valve 5 in the outlet of water tank 4, pipeline mounted pump 6 and outlet valve 7, outlet valve 7 inserts house steward 11, house steward's 11 axle envelope 9 and bearing cooling water pipes 10 that insert each ash pump in parallel, bearing cooling water pipe 10 links to each other with return main 12, return main 12 the other end inserts in the water tank 4, and the water in the axle envelope 6 enters in the pump housing.
Ash pump high pressure shaft seal cooling water cycling mechanism working procedure is: bypass valve 8 cuts out, allow the water of water inlet manifold 1 enter water tank 4 by intake pipe 3 by inlet valve 2, when treating water tank 4 water levels to 2/3, opening conduits pump water inlet valve 5 and pipeline mounted pump outlet valve 7, start pipeline mounted pump 6, the pressure of pump shaft seal water is brought up to 0.7MPa, high pressure water enters the axle envelope 9 and the bearing cooling water pipe 10 of every ash pump respectively through house steward 11, the axle water shutoff enters in the pump housing, and bearing cooling water is finished and entered return main 12 after the merit and be recycled to water tank 4 through utilizing again behind the cold filtrations.
