Description
Technical field
The present invention relates to a kind of pump, particularly, relate to a kind of pulp pump.
Background technique
In process of production sewage, slurries of papermaking enterprise, spraying water with high pressure etc. all needs to use water pump.Wherein the conveying of slurry is an important step in the papermaking enterprise, and this step must be finished by stock pump.
Pulp pump is a kind of special universal machine, because rotatablely moving of its distinctive runner form and impeller, make pump housing inside particularly exist whirlpool, the separation of flow, secondary back etc. all the time in the interior smoothness of impeller, make that the non-permanent turbulent flow in the pump is moved the complexity more that becomes.The waterpower of performance of over current component of water pump design for a long time, the velocity flow profile in flow field, pressure distribution etc. can only rely on reliable and detailed flow measurement progressively to improve, progressively solve in the centrifugal pump impeller, in paper industry, the pulp pump of carrying slurry is the key equipment in the paper production, pulp pump must cannot block stifledly, the pulp smoothness, balance movement.
But, existing pulp pump is because Component Design structural reason (example is the structure of the preceding wear-resisting lining of pulp pump as shown in Figure 5 and Figure 6), cause the conveying of pulp pump at thick slurry, when particularly being used in pulping and slagging-off step, have part chip solid thing and the long fibre thing can not pass through impeller, and be wrapped on the impeller, cause impeller to stop up, or even impeller is stuck, causes inefficiency, do not reach designing requirement, frequent cleaning, maintenance can not normally move whole production line, therefore, the pulp pump of prior art, the problem that can not effectively solve folder slurry in service and twine.
In view of this, need a kind of novel pulp pump of design.
Summary of the invention
The purpose of this invention is to provide a kind of novel pulp pump, to overcome the above-mentioned defective of prior art, this pulp pump can prevent from folder slurry and winding problem take place in the pulp pump running effectively, thereby avoids obstruction, stuck phenomenon.
Above-mentioned purpose is achieved through the following technical solutions: pulp pump, comprise the pump housing that has import and outlet, the impeller that is provided with preceding wear-resisting lining, back wear-resisting lining in this pump housing and is installed in pump shaft one end, the other end of described pump shaft reaches described pump housing outside, wear-resisting lining and wear-resisting lining space, back are also respectively around described impeller setting before described, wear-resisting lining, back wear-resisting lining and impeller surround the pulp passage between described import and outlet jointly before being somebody's turn to do, and radially are formed with a plurality of cutting grooves on the described preceding wear-resisting lining.
Preferably, be formed with four cutting grooves on the described preceding wear-resisting lining, the angle between the wherein adjacent described cutting groove is 90 °.
Particularly, the rear portion of the described pump housing is provided with opening, and this opening seals by bonnet.
Particularly, the other end of described pump shaft passes the through hole at described bonnet center and reaches the outside of the described pump housing, and seals by mechanical sealing element.
Selectively, in support housing, the other end of described pump shaft stretches out described support housing and coupling is installed the part that this pump shaft stretches out described pump housing outside by bearings.
Selectively, described support housing is provided with tank filler sleeve, drain oil and oily window, and described tank filler sleeve is by the plug cock jam-pack.
Selectively, on the described support housing support is installed.
By technique scheme, the present invention has set up cutting groove on present preceding wear-resisting lining, and it can promptly will effectively cut through here long fibre and thick the slurry, the assurance slurry is discharged smoothly, greatly reduce maintenance rate, saved maintenance cost, improved working efficiency.The present invention is when carrying out technological improvement, guaranteed again and existing product interchangeability, it has preserved the installation dimension and the profile of existing product substantially, therefore wear-resisting lining can drop into ordinary production before any same category of device only need be changed, for the user provides great convenience, have good technical adaptability and using value.
