Technical field
The present invention relates to a kind of slag stock pump bearing lubrication system, particularly the dual-purpose slag stock pump bearing lubrication system of a kind of lubricating grease and thin oil.
Background technique
The slag stock pump, as a kind of two-phase solid-liquid fluid conveying equipment, is widely used in multiple industry.During use, the slag stock pump generally need to be used in conjunction with bearing unit, and bearing unit is as transferring power and drive the vitals of the vane rotary of slag stock pump, for the smooth running of slag stock pump, plays critical effect.For guaranteeing the smooth running of slag stock pump, need to the bearing that bearing unit inside arranges be lubricated, difference according to the equipment operating conditions, the bearing lubrication mode that often adopts comprises two kinds, be respectively thin oil lubricant and grease lubrication, thin oil lubricant generally be applicable to underloading, at a high speed, the running environment of high temperature, and grease lubrication generally is applicable to the running environment of heavy duty, low speed, low temperature.
The grease lubricating bearing assembly becomes the first-selected structure of slag stock pump because of simple in structure, working service convenience, lubricant oil without advantages such as leakages at present, but the slag stock pump will adopt the bearing unit of thin oil lubricant when carrying high temperature fluid, and lubricant oil is carried out to water cooling, to reach bearing lubrication preferably and cooling effect.So sometimes, the slag stock pump of same model need to meet different operating modes, and for meeting different users' usage requirement, the slag stock pump that need to develop a kind of same model possesses the bearing unit of 2 kinds of lubricating systems simultaneously.
Summary of the invention
In order to address the above problem, the invention provides the dual-purpose slag stock pump bearing lubrication system of a kind of lubricating grease and thin oil, this invention can be selected different lubricating systems according to different operating modes, has versatility, has greatly improved the application area of slag stock pump.
The present invention is achieved by the following technical solution: the slag stock pump bearing lubrication system that a kind of lubricating grease and thin oil are dual-purpose, comprise carriage and be arranged on the bearing unit in carriage, it is characterized in that, described carriage comprises pallet body and bay cover, described bay cover is covered on pallet body, and the inside of described pallet body is provided with oil pocket; Left bearing and right bearing that described bearing unit comprises pump shaft and is arranged on two ends, pump shaft left and right, the left side of described left bearing and the right side of right bearing are respectively by labyrinth axle sleeve and bearing gland sealing; The oil pocket that arranges corresponding to pallet body inside on described bay cover is provided with the thin oil oil hole, the left bearing that arranges corresponding to the pump shaft two ends on described bay cover and right bearing place correspondence respectively are provided with the lubricating grease forced filling oil cup, the interior edge face of described left bearing and right bearing correspondence respectively is provided with left bearing back-up ring and right bearing back-up ring, between described left bearing back-up ring and right bearing back-up ring and pallet body and bay cover, all leaves gap.
The gap that arranges between described left bearing back-up ring and right bearing back-up ring and pallet body and bay cover is 2-3mm.
Described left bearing and right bearing are double-row conical bearing.
The two ends of described bay cover are provided with cooling water chamber near the position that is provided with left side and right bearing, and the top of described cooling water chamber is provided with the cooling water chamber gland.
The invention has the beneficial effects as follows:
1, the invention solves two kinds of bearing lubrication modes of slag stock pump is the problem that grease lubrication and thin oil lubricant are changed mutually, and the present invention both can adopt grease lubrication also can adopt thin oil lubricant, had versatility.
The characteristics such as 2, this invention has simple in structurely, reasonable in design, and manufacturing is easy, and working service is convenient.
The accompanying drawing explanation
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention;
In figure: 1-carriage, 11-pallet body, 111-oil pocket, 12-bay cover, 2-bearing unit, 21-pump shaft, 22-left bearing, 221-left bearing back-up ring, 23-right bearing, 231-right bearing back-up ring, 3-labyrinth axle sleeve, 4-bearing gland, 5-thin oil oil hole, 6-lubricating grease forced filling oil cup, 7-cooling water chamber, 71-cooling water chamber gland.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1, the slag stock pump bearing lubrication system that a kind of lubricating grease of the present invention and thin oil are dual-purpose, it comprises carriage 1 and is arranged on the bearing unit 2 in carriage, described carriage 1 comprises pallet body 11 and bay cover 12, described bay cover 12 is covered on pallet body 11, and the inside of described pallet body 11 is provided with oil pocket 111; Left bearing 22 and right bearing 23 that described bearing unit 2 comprises pump shaft 21 and is arranged on pump shaft 21 two ends, left and right, the right side of the left side of described left bearing 22 and right bearing 23 are respectively by labyrinth axle sleeve 3 and bearing gland 4 sealings; On described bay cover 12, corresponding to the inner oil pocket that arranges of pallet body 11, be provided with thin oil oil hole 5, the left bearing 21 that arranges corresponding to pump shaft 21 two ends on described bay cover 11 and right bearing 22 places correspondence respectively are provided with lubricating grease forced filling oil cup 6, the interior edge face of described left bearing 22 and right bearing 23 correspondence respectively is provided with left bearing back-up ring 221 and right bearing back-up ring 231, between described left bearing back-up ring 221 and right bearing back-up ring 231 and pallet body 11 and bay cover 12, all leaves gap.
The gap that arranges between described left bearing back-up ring 221 and right bearing back-up ring 231 and pallet body 11 and bay cover 12 is 2-3mm.
Described left bearing 22 and right bearing 23 are double-row conical bearing.
The two ends of described bay cover 12 are provided with cooling water chamber 7 near the position that is provided with left bearing 22 and right bearing 23, and the top of described cooling water chamber 7 is provided with cooling water chamber gland 71.
When needs adopt grease lubrication, only lubricating grease need be entered in left bearing 22 and right bearing 23 and can realize the grease lubrication to bearing by lubricating grease forced filling oil cup 6.In addition, left bearing back-up ring 221 and right bearing back-up ring 231 are 2～3mm with the inwall of pallet body 11 and the gap of bay cover 12, can stop like this lubricating grease to enter in a large number in oil pocket 111, thereby guarantee the lubricating grease amount of bearing abundance.
When adopting the thin oil lubricant mode, the thin oil oil hole 5 that can pass through to arrange on bay cover 12 is to the interior injection lubricant oil of oil pocket 111, lubricant oil in oil pocket 111 easily arrives in left bearing 22, right bearing 23 by inwall and the gap between bay cover of left bearing back-up ring 221, right bearing back-up ring 231 and pallet body 11, can realize the oil lubrication of bearing.
In addition, during use, to cooling water chamber 7 pass into recirculated cooling water bearing is carried out cooling, to reduce the operating temperature of bearing, the working life of improving bearing.
The present invention, in the situation that conversion lubrication system has more not been realized the conversion of these two kinds of lubricating systems of grease lubrication and thin oil lubricant, has saved cost of production, has improved the application area of slag stock pump.
Except the described technical characteristics of above-mentioned specification, be the known technology of those skilled in the art.
