Abstract
The utility model discloses a sealed gear ammonia pump used in an ammonia cooling circular system. The utility model is characterized in that a sealing device for corrugated pipes and expansion pipes are connected and additionally arranged between the ammonia pump and a motor; gland seal subassemblies for graphite, a rubber loop, a blocking ring and a spring are arranged in a corrugated pipe on one side of the motor; the corrugated pipe and a motor end cover are provided with asbestos cushions which are connected together by threads; the other end of the corrugated pipe is connected with a gland seal flange of the ammonia pump by the asbestos cushions and threaded bolts. A flange of the corrugated pipe connected with the motor is provided with an ammonia pressure gauge valve and a purge valve. A flange of the corrugated pipe connected with the gland seal flange of the ammonia pump is provided with an oil feeding valve. The utility model solves the problem of the leakage of ammonia of the existing gear ammonia pumps and reaches to the requirement of environmental protection.
Description
The utility model relates to a kind of gear ammonia pump, particularly closed-end gear ammonia pump, is used for the ammonia refrigeration circulatory system.
The gear pump of refrigeration industry use at present has only the axle envelope at the axle envelope place that connects with motor, owing to seal bad, often leak ammonia aborning, cause the waste of refrigeration agent, also cause environmental pollution, during the running negative pressure, cause air to enter in the system, refrigeration is descended.
In view of the deficiency of above-mentioned technology, the purpose of this utility model provides a kind of ammoniacal liquor that can prevent and leaks, and guarantees the closed-end gear ammonia pump of environmental requirement.
The purpose of this utility model can realize by following technological scheme: the closed-end gear ammonia pump, comprise base, motor, shaft joint, the corrugated expansion pipe seal arrangement, in motor one side bellows, be provided with a cover and comprise graphite, cushion rubber, baffle ring, the gland seal assembly of spring, bellows end and electric motor end cap are equipped with the asbestos packing Bolt Connection, the bellows the other end and ammonia pump axle envelope flange asbestos packing, Bolt Connection, the bellows the other end and ammonia pump axle envelope flange asbestos packing, bolt seal connects, be provided with the pressure meter valve of surveying ammonia pressure in the bellows at the bellows flange place that is connected with motor, and be provided with bleed valve, with bellows flange that ammonia pump axle envelope flange connects on be provided with priming valve.
The utility model compared with prior art because the joint between motor and pump is provided with bellow seal, effects a radical cure gear ammonia pump leakage ammoniacal liquor and also avoids air to enter in the circulatory system, guarantees environmental requirement.
Accompanying drawing is the utility model structural representation.
Specifically describe the utility model embodiment below in conjunction with accompanying drawing.Shown in accompanying drawing, motor 2 can be 10 utmost points-3.0KW, motor shaft can extend and export end cap and match with the flange of corrugated expansion pipe (7) through processing, on corrugated expansion pipe (7) and the joining bellows flange of motor, pressure meter valve (3) is housed, whether can in time react this ammonia pump reveals, be provided with the bleed valve (4) that communicates with bellows simultaneously on this flange top, the air-breathing mouth of pipe of bleed valve (4) outlet termination refrigerating machine, when treating that ammonia pump is revealed, so that can put the pressure of clean bellows fully, maintenance is also convenient, and bellows (7) adopts the 1Cr18Ni9Ti material, and two ends connect with the bolt seal of electric motor end cap gear pump shaft envelope flange with asbestos packing and 8 cover M16 respectively, on the extension shaft of motor output, be provided with QT40 magnesium iron baffle ring, oil resistant rubber seal ring two roads, the graphite workpiece, axle envelope spring assembly gland seal assembly (5) together, coupling is equipped with at the spindle nose place, there is the oil resistant blob of viscose centre, with the shaft joint of gear pump input spindle nose, cast iron HT20 joins, the normal operation of driven gear pump LP.
