Abstract
The utility model discloses a kind of single-stage double-suction that improves sealing and open energy-saving pump in axially, the pump shaft of this pump is by the bearing body part supporting on the pump housing, impeller is fixedly equipped with at the middle part of pump shaft, and on the upper-end surface of the pump housing, pump cover is equipped with in sealing, and water sealing (sealing water) pipe parts are equipped with at the two ends of pump cover; Labyrinth collar is equipped with in the contacting point of the two ends outer rim of impeller and pump cover, the pump housing; The mechanical seal parts that prevent that liquid from revealing are equipped with at the two ends of pump shaft, the pump housing and place, pump cover side, and the adjustment ring of adjusting its parts sealing effect is housed on the inner side pump shaft of mechanical seal parts.Due to the employing of labyrinth collar, can effectively prevent that the liquid of hyperbaric chamber from revealing to low-pressure cavity, increased cooperation place lubricity; By regulating adjustment ring can make mechanical seal parts be adapted to the mechanical seal of different occasions, different medium, thereby improve the working efficiency of pump, saved the energy, extended the working life of water pump.
Description
One, technical field
The utility model relates to a kind of single-stage double-suction and opens in axially energy-conservationly, and especially a kind of single-stage double-suction that improves sealing is opened energy-saving pump in axially.
Two, background technique
Current, people open energy-saving pump for delivery of water and the single-stage double-suction with slight corrosion liquid in axially in occasions such as steel mill, power plant, chemical industry, oil field, heating, and its structure is comprised of the pump housing, pump shaft, impeller and pump cover.In order to prevent that the liquid of hyperbaric chamber from revealing to low-pressure cavity, in the contacting point of the two ends of impeller outer rim and pump cover, the pump housing, seal ring is housed; The packing_seal circle that prevents that liquid from revealing is equipped with at the two ends of pump shaft., in pump using process, due to the wearing and tearing of Sealing, easily cause liquid to reveal, affect working efficiency and the working life of pump.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of single-stage double-suction that improves sealing and opens energy-saving pump in axially.
The technological scheme that realizes the purpose of this utility model employing is: during this single-stage double-suction is axial, open energy-saving pump and mainly the pump housing, bearing body part, pump cover, water sealing (sealing water) pipe parts, seal ring, impeller, mechanical seal parts and adjustment ring, consist of; Pump shaft is by the bearing body part supporting on the pump housing, and impeller is fixedly equipped with at the middle part of pump shaft, and on the upper-end surface of the pump housing, pump cover is equipped with in sealing, and water sealing (sealing water) pipe parts are equipped with at the two ends of pump cover; The contacting point of the two ends outer rim of impeller and pump cover, the pump housing is equipped with and is prevented that the liquid of hyperbaric chamber is to the labyrinth collar of low-pressure cavity leakage; The mechanical seal parts that prevent that liquid from revealing are equipped with at the two ends of pump shaft, the pump housing and place, pump cover side, and the adjustment ring of adjusting its parts sealing effect is housed on the inner side pump shaft of mechanical seal parts.
The beneficial effects of the utility model are: because labyrinth collar is equipped with in the contacting point of the two ends outer rim of impeller and pump cover, the pump housing, can effectively prevent that the liquid of hyperbaric chamber from revealing to low-pressure cavity, increase cooperation place lubricity; By regulating adjustment ring can make mechanical seal parts be adapted to the mechanical seal of different occasions, different medium.Thereby improved the working efficiency of pump, saved the energy, extended the working life of water pump.
Four, accompanying drawing explanation
Fig. 1 is the main sectional view that a kind of single-stage double-suction that improves sealing of the utility model is opened energy-saving pump in axially.
Fig. 2 is the enlarged view that a kind of single-stage double-suction that improves sealing of the utility model is opened Fig. 1-A place of energy-saving pump in axially.
Fig. 3 is the enlarged view that a kind of single-stage double-suction that improves sealing of the utility model is opened Fig. 1-B place of energy-saving pump in axially.
Five, embodiment
In the accompanying drawings, a kind of single-stage double-suction that improves sealing of the utility model is opened energy-saving pump in axially and mainly the pump housing, bearing body part, pump cover, water sealing (sealing water) pipe parts, seal ring, impeller, mechanical seal parts and adjustment ring, is consisted of; Pump shaft 9 is by bearing body part 2 supportings on the pump housing 1, and impeller 6 is fixedly equipped with at the middle part of pump shaft 9, and on the upper-end surface of the pump housing 1, pump cover 3 is equipped with in sealing, and water sealing (sealing water) pipe parts 4 are equipped with at the two ends of pump cover 3; Labyrinth collar 5 is equipped with in the contacting point of the two ends outer rim of impeller 6 and pump cover, the pump housing; The employing of labyrinth collar 5, is not only conducive to the lubricity that coordinates, improves its working life, improves sealing simultaneously, reduces medium back flow, improves the working efficiency of pump.The mechanical seal parts 8 that prevent that liquid from revealing are equipped with at the two ends of pump shaft, the pump housing and place, pump cover side, and the adjustment ring 7 of adjusting its parts 8 sealing effects is housed on the inner side pump shaft of mechanical seal parts 8.Turn and adjust screw 10 (seeing Fig. 3), adjustment ring 7 can be fixed on the diverse location of axle sleeve, makes mechanical seal parts 8 be adapted to the mechanical seal of different occasions, different medium; Also can in the situation that not dismantling pump cover, change, servicing machine sealed member, save time, convenient.Owing to having adopted new sealing configuration, improved the working efficiency of pump, saved the energy, extended the working life of water pump.
