Abstract
The utility model relates to a process pump, in particular to an automatic flushing filtering device for a process pump. According to the technical scheme, the device comprises a flushing pipe joint and a pump joint, wherein the flushing pipe joint is in threaded connection with the pump joint; and a filtering screen is arranged in the flushing pipe joint and the pump joint. The filtering device has the advantages that the device is convenient to install and maintain, low in manufacturing cost and easy to process, has a simple structure and can meet the requirement of a filtering medium, the life cycle of a mechanical seal can be effectively prolonged, and the material cost and manual maintenance cost of the mechanical seal are saved.
Description
Technical field
The utility model relates to a kind of process pump, the automatic washing and filtering device of particularly a kind of process pump.
Background technique
Process pump is the pipeline conveying device of using always; Use to such an extent that process pump is fit to the medium that conveying does not contain solid particle at present; Find during use that the mechanical seal replacement cycle is very fast, analyzes the mechanical seal failure cause: eliminating machine envelope itself is made reason, thinks because flushing medium contains granule foreign; Granule foreign gets into Seal cage can scratch sealing surface, and the cellulosic material gets into Seal cage also can make the sealing surface liquid film destroyed.Solid impurity is deposited in dynamic and static ring auxiliary seal place, can influence the floatability of seal ring, is deposited on the bellows place and can causes " mistake bullet " phenomenon, and the medium that contains granule foreign directly impacts the destruction that seal face can cause seal face.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to existing technology, provides a kind of process pump automatic washing and filtering device, has simple in structurely, cheaply is easy to processing, can reach the purpose of filter medium.
Its technological scheme is: comprise cleaning hose joint, pump joint, described cleaning hose joint and pump joint are through being threaded described cleaning hose joint and pump joint set inside filter screen.
The above-mentioned cleaning hose joint and the joint of pump joint are provided with groove.
The beneficial effect of the utility model is: installation and maintenance are convenient, the effective life cycle that seals of prolonged mechanical, this filtrating equipment; Have simple in structure; Cheap being easy to processed, and can reach the requirement of filter medium, practiced thrift the Master Cost and the artificial maintenance expenses of mechanical seal.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is structural representations of filter screen 4.
Embodiment
In conjunction with accompanying drawing 1-2, the utility model is done further to describe:
The utility model comprises cleaning hose joint 1, pump joint 2, and described cleaning hose joint 1 and pump joint 2 are through being threaded described cleaning hose joint 1 and pump joint 2 set inside filter screens 4; Described cleaning hose joint 1 is provided with groove 3 with the joint of pump joint 2.
Installation and maintenance are convenient, the effective life cycle of prolonged mechanical sealing, and this filtrating equipment has simple in structurely, and cheap being easy to processed, and can reach the requirement of filter medium, practiced thrift the Master Cost and the artificial maintenance expenses of mechanical seal.
