Description

A kind of heavy type slurry pump of fast demountable overcurrent assembly
Technical field
The utility model relates to a kind of heavy type slurry pump of fast demountable overcurrent assembly, belongs to slag stock pump field.
Background technique
Slag stock pump is mainly used in the industries such as mine, electric power, metallurgy, coal, environmental protection and carries the slurry that contains abrasion solid particle.As technics of metallurgy mineral dressing factory pulp conveying, thermal power plant's hydraulic(-ash) sluicing, coal washery coal slurry and dense media are carried, river training, river desilting etc.At chemical industry, the corrosivity slurry that also can carry some to contain crystallization.Because the applied environment of slag stock pump is comparatively harsh, therefore for slag stock pump after continuous operation a period of time, need to change in time the component after loss, to guarantee the reliability of its work.
Conventional method is that the problem that solves replacing loss component mainly adopts following two schemes: scheme one, design stand by pump and another parallel connection of pumps, form one and open a standby working state.Break down or when component loss, can start rapidly stand by pump at working pump.This scheme can guarantee that whole system moves continuously, the reliability of raising system, but this scheme need to increase a pump and relevant equipment, as motor, speed reducer, control panel etc., under the condition not using, also need to make regular check on maintenance, use and maintenance cost is higher.
Scheme two, keep the spare part of certain easy wearing detail, after component loss, change in time easy wearing detail.This scheme has reduced user cost compared with stand by pump structure, and has reduced the regular maintenance operation to double pump, is the choosing with the expectation of pump enterprise.But the linkage structure of the easy wearing detail of existing slag stock pump and whole pump is as shown in Figure 1, comprise transmitting assemblies and overcurrent assembly, wherein easily wearing detail is overcurrent assembly.Flow passage part assembly process is as follows: first rear pump shell be installed to the transmission part having installed and be fixed on bracket by elongate bracket bolt and short bracket bolt, stripping ring and axle sleeve install on axle successively, then the Stuffing box that packs filler and seal cage into is installed to rear pump shell, sub-propeller is fixed on axle by key, rear backplate is secured by bolts on rear pump shell and compresses Stuffing box simultaneously, impeller can be installed afterwards to axle, spiral case, apron plate, the component such as front pump shell; Contrary with said process when dismounting.While changing overcurrent assembly; must be first by system-down; carrying out above-mentioned dismantlement work consuming time; almost the part of each overcurrent assembly is disassembled; change the part of wearing and tearing; again each part is installed on transmission part, ability restarting systems, the pump that cannot meet some needs non-stop run uses field.
Model utility content
The purpose of this utility model is need to dismantle whole overcurrent assembly in order to solve when traditional slag stock pump structure is changed overcurrent assembly; cause system downtime long or for to guarantee that non-stop run is forced to use the technological difficulties of the stand by pump system that cost is higher, and a kind of heavy type slurry pump of fast demountable overcurrent assembly is provided.
The purpose of this utility model is achieved through the following technical solutions:
The heavy type slurry pump of a kind of fast demountable overcurrent assembly of the present utility model, is characterized in that: comprise transmitting assemblies and overcurrent assembly;
Transmission part comprises bracket, axle sleeve, front dust pan, fore bearing gland, gland, bearing housing, rear bearing gland, rear dust pan, pump shaft;
Wherein, the front end thread section of pump shaft is with tapering trapezoidal thread;
Overcurrent assembly comprises rear pump shell, rear backplate, spiral case, apron plate, front pump shell, impeller, sub-propeller;
The internal thread of impeller hub is the tapering trapezoidal thread matching with pump shaft front end thread section; The hole front end that passes through of sub-propeller is processed with the circular orientation platform matching with impeller hub end cylindrical profile;
Backplate after socket on the wheel hub of impeller, sub-propeller is enclosed within impeller hub end by it by hole front end annular positioning table, makes three's radial location, and three outside is packaged into whole by rear pump shell, spiral case, apron plate and front pump shell again;
Sub-propeller one end of overcurrent assembly is enclosed within on pump shaft, fixes, and on the pump shaft of rear pump shell rear end, packing seal is installed by bolt with by rear pump shell and bracket.
Working procedure:
While changing overcurrent assembly, only need untie and connect the bolt that rear pump shell connects with bracket, use frock to prevent vane rotary in the ingress of pump, lifting overcurrent assembly, by rotation pump shaft, overcurrent assembly integral demounting is got off, then intact overcurrent assembly integral installation for subsequent use is got on, recover the operation of pump.The overall overcurrent assembly disassembling, through strip inspection, re-assemblies after the part of replacing loss, can be used as the spare part while maintenance next time.
Beneficial effect:
The structure of a kind of heavy type slurry pump overcurrent of the utility model assembly fast assembling-disassembling, the overcurrent component design of slag stock pump is become to independently whole, make to change overcurrent part more convenient, shorten slag stock pump and change overcurrent component hour, reduce stand by pump quantity, reduce relevant cost.
