Abstract
The utility model discloses an anti-pollution liquid ammonia pump which solves the problem that a small amount of sealing oil is brought to a liquid ammonia system in the current liquid ammonia pump to pollute liquid ammonia. The anti-pollution liquid ammonia pump comprises a crankcase (5). The input end of a reducer (3) is connected with the output shaft of a drive motor (1) through a high speed coupler (2), and the output shaft of the crankcase (5) is connected with the bottom end of a plunger (6). A stuffing box (7) is arranged between the top end of the plunger (6) and the inner wall of a plunger sleeve (14). The stuffing box (7) is internally provided with a sealing water circular chamber (8). The plunger sleeve (14) is respectively provided with a desalted water inlet (9) and a desalted water outlet (10) communicated with the sealing water circular chamber (8). A liquid ammonia cylinder (11) is provided with a liquid ammonia inlet (12), and a liquid ammonia outlet (13) compressed is arranged on the upper part of the plunger sleeve (14). The stability of quality in the production process of the liquid ammonia is improved.
Description
Technical field
The utility model relates to a kind of ammonia pump.
Background technique
Ammonia pump is the visual plant in the nitrogen fertilizer production process, and the mutual motion between the plunger of ammonia pump and plunger packing are former is for ammonia pump provides compressing force.Sealing in the existing plunger packing is generally oil seal, in the actual production running, a small amount of sealing oil usually can occur be brought in the liquefied ammonia system, causes the pollution of liquefied ammonia, has had influence on the steady quality of subsequent product.
Summary of the invention
The utility model provides a kind of anti-pollution ammonia pump, has solved a small amount of sealing oil of the easy generation of existing ammonia pump and has been brought in the liquefied ammonia system, causes the technical problem of the pollution of liquefied ammonia.
The utility model is by the above problem of following solution:
A kind of anti-pollution ammonia pump, comprise crankcase, the input shaft of crankcase is by the output shaft mechanical connection of low-speed shaft coupler and retarder, the input shaft of retarder is connected with the output shaft of drive motor by high-speed coupling, the output shaft of crankcase is connected with the bottom of plunger, the top of plunger is arranged in the plunger guide bush, between the inwall of the top of plunger and plunger guide bush, be provided with stuffing box, in stuffing box, be provided with sealing water doughnut, be respectively arranged with and seal demineralized water entrance and the demineralized water outlet that the water doughnut is communicated with at plunger guide bush, be provided with liquefied ammonia on the top of plunger guide bush and enter one-way valve, plunger guide bush enters one-way valve by liquefied ammonia and is communicated with the liquefied ammonia cylinder body, be provided with the liquefied ammonia entrance at the liquefied ammonia cylinder body, be provided with compressed liquefied ammonia outlet on the top of plunger guide bush.
The demineralized water entrance is communicated with system desalination water tank, and the demineralized water outlet is communicated with ammonia vessel.
The utility model has solved the problem of the lubricant pollution of liquefied ammonia production link, has improved liquefied ammonia mass stability in process of production.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of anti-pollution ammonia pump, comprise crankcase 5, the input shaft of crankcase 5 is by the output shaft mechanical connection of low-speed shaft coupler 4 with retarder 3, the input shaft of retarder 3 is connected with the output shaft of drive motor 1 by high-speed coupling 2, the output shaft of crankcase 5 is connected with the bottom of plunger 6, the top of plunger 6 is arranged in the plunger guide bush 14, between the inwall of the top of plunger 6 and plunger guide bush 14, be provided with stuffing box 7, in stuffing box 7, be provided with sealing water doughnut 8, be respectively arranged with and seal demineralized water entrance 9 and the demineralized water outlet 10 that water doughnut 8 is communicated with at plunger guide bush 14, be provided with liquefied ammonia on the top of plunger guide bush 14 and enter one-way valve 15, plunger guide bush 14 enters one-way valve 15 by liquefied ammonia and is communicated with liquefied ammonia cylinder body 11, be provided with liquefied ammonia entrance 12 at liquefied ammonia cylinder body 11, be provided with compressed liquefied ammonia outlet 13 on the top of plunger guide bush 14.
