Abstract
The utility model relates to a novel vertical type multistage pipeline pump bearing body structure comprising a pump body, a water inlet-outlet segment, an upper bearing body, a lower bearing body, an impeller, a jacket shaft coupling, a pump shaft, a mechanical seal gland, and a mechanical seal. The utility model is characterized in that a rubber bearing is respectively disposed on the upper part and on the lower part of the pump shaft; the upper rubber bearing is disposed in the upper bearing body, and the lower rubber bearing is disposed in the lower bearing body; the upper bearing body is connected with the pump body and the mechanical seal gland by spigots in a cooperated manner; the lower bearing body is connected with the water inlet-outlet segment by a spigot in a cooperated manner. The utility model is advantageous in that when the bearing is required to be replaced, the inside rubber bearings can be replaced by disassembling the upper and the lower bearing bodies, and only a few of parts related to the bearings are required to be disassembled, besides, the reassembly can be very convenient after the replacement.
Description
Technical field
The utility model relates to a kind of novel vertical multi-stage pipeline mounted pump bearing support structure.
Background technique
Existing vertical multi-stage pipeline mounted pump adopts the rubber bush bearing structure, and rubber bush bearing has characteristics such as cheap, easy for installation, but service life is shorter, needs often to change.Just bother very much by original structure dismounting and change rubber bush bearing, or even remove complete machine.Therefore demand developing novel vertical multi-stage pipeline mounted pump bearing support structure urgently to address the above problem.
Summary of the invention
The purpose of the utility model is that vertical multiple valve road pump structure is often changed the problem of rubber bush bearing because of adopting the existing needs of rubber bush bearing in the solution existing technology; The utility model designs a kind of vertical multi-stage pipeline mounted pump of novel easy replacing bearing; Comprise the pump housing, water inlet-outlet segment, upper bearing (metal) body, lower bearing body, impeller, jacket coupling, pump shaft, machine sealed cover, machine envelope; It is characterized in that: a rubber bush bearing respectively is installed up and down at pump shaft; Two rubber bush bearings respectively are installed in upper bearing (metal) body and the lower bearing body up and down, and the upper bearing (metal) body and the pump housing and machine sealed cover are connected by seam, and lower bearing body and water inlet-outlet segment are connected by seam.The utility model has the advantages that when needs are changed bearing, pull down upper and lower bearing support, the rubber bush bearing in promptly replaceable being installed in only needs the several parts relevant with bearing of dismounting, reinstalls also very convenient after the replacing.
Description of drawings
Below in conjunction with the accompanying drawing instance the utility model is elaborated.Fig. 1 is the structural representation of the utility model.
Embodiment
Comprise the pump housing 1, water inlet-outlet segment 2, upper bearing (metal) body 3, lower bearing body 4, impeller 5, jacket coupling 6, pump shaft 7, machine sealed cover 8, machine envelope 9 among the figure; It is characterized in that: a rubber bush bearing 10 respectively is installed up and down at pump shaft; Two rubber bush bearings respectively are installed in upper bearing (metal) body and the lower bearing body up and down; The upper bearing (metal) body and the pump housing and machine sealed cover are connected by seam, and lower bearing body and water inlet-outlet segment are connected by seam.
When working as following rubber bush bearing damage in the practical process; Panasonic's connecting bolt breaks away from the pump housing with the lower bearing body and pulls out the rubber bush bearing replacing that just can take damage out of; The lower bearing body cooperates through seam with water inlet-outlet segment, and sealing is reliable and this structure water inlet-outlet segment is made mould and the casting difficulty all reduces.When upper bearing (metal) bad time, to remove jacket coupling, machine sealed cover, machine and be honored as a queen the upper bearing (metal) body pulled out to take top rubber bush bearing out of and change, the back that finishes is loaded onto by reverse procedure and is got final product.The method has avoided removing the possibility of whole pump, and is simple and very reliable.
