Abstract
The utility model discloses an energy-saving slurry pump, which includes a bearing pedestal, a pump body fixed on one side of the bearing pedestal, and a pump casing fixed in the pump body. A pump shaft is mounted on the bearing pedestal, and the front end of the pump shaft is inserted into the pump casing; an impeller connected with the pump shaft is arranged in the pump casing; and a seal device is arranged between the pump body and the pump casing on the pump shaft. The energy-saving slurry pump is characterized in that the seal device comprises a stuffing box body arranged between the pump body and the pump casing and mounted on the pump shaft in a sleeving manner, a stuffing seal arranged between the stuffing box body and the pump shaft, and a stuffing gland fixed at the outer end of the stuffing box body. The energy-saving slurry pump has the advantages as follows: the seal device comprises the stuffing box body, the stuffing seal and the stuffing gland, and replaces static seal and motive seal of the traditional slurry pump, so that the structure is simple and the installation is convenient; and motive seal, namely an auxiliary impeller, is eliminated, and the added load caused by the auxiliary impeller is eliminated, so that the work efficiency is high, the energy-saving effect is good, and practices prove that energy can be saved about 7-10%.
Description
Technical field
The utility model is particularly related to a kind of energy-saving slag stock pump.
Background technique
Ore dressing plant or some other need the enterprise of deslagging, need a large amount of circulating water aborning, need to use the slag stock pump that mine tailings are emitted.Therefore slag stock pump power consumption quantity is very huge.The slag stock pump that uses is the product of the 60 to 70's of last century research and development at present, complex structure, inefficiency, and because this pump will discharge mine tailing, therefore wearing and tearing are very serious, non-leakage in order to ensure proper functioning, on pump shaft, be positioned at the pump housing and be provided with static seal and motive sealing near motor one side ports, its static seal is to be made of the oil immersion asbestos packing that is enclosed within Stuffing box, the Gland on the pump shaft and be located in the Stuffing box, and its motive sealing is to be fixed on the sub-propeller between Stuffing box and pump housing inner casing on the pump shaft.Though sub-propeller can prevent the medium of carrying and leak, and has increased load, has consumed very big energy.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, high working efficiency, the energy-saving slag stock pump of good energy-conserving effect.
The energy-saving slag stock pump that the utility model relates to comprises bearing support, is fixed on the pump housing of bearing support one side and is fixed on the interior pump case of the pump housing, pump shaft is installed on bearing support and the pump shaft front end is inserted in the pump case, in pump case, be provided with the impeller that is connected with pump shaft, between the pump housing and pump case, be provided with seal arrangement on the pump shaft, its special way is: described seal arrangement is by being fixed between the pump housing and the pump case and being sleeved on stuffing box body on the pump shaft, and the Gland that is located at the packing seal between stuffing box body and the pump shaft and is fixed on the external end of stuffing box constitutes.
Above-mentioned energy-saving slag stock pump is positioned at stuffing box body inner port place and is installed with slag blocking ring, to stop bigger clinker on pump shaft.
Above-mentioned energy-saving slag stock pump, corresponding seal arrangement place is installed with axle sleeve on pump shaft, and described seal arrangement is installed on the axle sleeve, to improve the working life of pump shaft.
Above-mentioned energy-saving slag stock pump is provided with the water injection hole that tilts to its inner port on the stuffing box body, so that use high pressure water washing slag slurry.
The utility model has the advantages that: because seal arrangement is by the stuffing box body, the packing seal and the Gland that are located between stuffing box body and the pump shaft constitute, and have replaced the static seal and the motive sealing of traditional slag stock pump, and be therefore simple in structure, easy for installation; Owing to cancelled motive sealing-sub-propeller, eliminated the load that increases because of sub-propeller, so high working efficiency, good energy-conserving effect facts have proved to can save energy about 7-10%.
