Description
Technical Field
The utility model relates to a pumping installations technical field, concretely relates to lubricated transmission of submerged pump rotor.
Background
A pump is a machine that delivers or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, causing the liquid energy to increase. The pump is mainly used for conveying liquid such as water, oil, acid-base liquid, emulsion, suspension emulsion and liquid metal, and can also be used for conveying liquid, gas mixture and liquid containing suspended solid. Pumps can be generally classified by their operating principle into three types, positive displacement pumps, dynamic pumps and other types of pumps.
The submerged pump is a common pump body, is an important pump product of industrial pumps, and along with the scale and refined production of national production, the submerged pump is not only used in the weak corrosion industries such as clear water and waste liquid pumping, but also plays an important role in the pumping process of underground acid, alkali, salt and wastewater ponds in various industries such as medicine, chemical engineering, nonferrous metallurgy, environmental protection wastewater treatment and the like.
A guide bearing sleeve inlet of the conventional submerged pump is lack of a diversion and homogeneous structural part, so that liquid inlet is uneven, impact damage is easily caused to parts such as an internal impeller, the service life is shortened, and the working efficiency is low.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing a lubricated transmission of submerged pump rotor.
In order to realize the technical purpose, the utility model discloses a scheme is:
as preferred, a lubricated transmission of submerged pump rotor, including the pump body and pump shaft, pump body upper end have the pump cover through the screw connection, the pump shaft bottom be fixed with impeller, its characterized in that through the impeller nut: a positioning sleeve is fixed at the upper end of the pump cover through a screw, a guide bearing sleeve is arranged in a groove in the inner wall of the positioning sleeve, and an alloy sleeve is arranged on the inner ring of the guide bearing sleeve and on the outer ring of the pump shaft; a plurality of flushing cooling ports are transversely and annularly arranged between the pump cover and the positioning sleeve; the inner ring of the guide bearing sleeve is annularly provided with a plurality of grooves.
Preferably, the inlet of the flushing cooling port is arranged at the outer end of the pump cover, and the tail end of the flushing cooling port extends to the alloy sleeve.
Preferably, the guide bearing sleeve inner ring is annularly provided with 4 groups of grooves, and the grooves are matched with the alloy sleeve to form 4 groups of through passages.
Preferably, the guide bearing sleeve and the alloy sleeve are both made of hard alloy materials.
The beneficial effects of the utility model, lead bearing housing and alloy axle sleeve and all adopt the carbide material, be suitable for and carry sediment thick liquid or a small amount of granule impurity medium, lead the bearing housing inner circle and set up four or a plurality of recesses, the medium of being convenient for leads bearing housing and alloy axle sleeve through the lubrication, sets up the flushing cooling mouth on pump cover and locating sleeve for the alloy cover rotates that the friction is overheated, and the bearing housing is led in the flushing cooling.
