Description
Technical Field
The invention relates to the water treatment industry, in particular to the aspects of deep filtration and purification of drinking water.
Background
In the water purifier, a booster pump is required for a water purification machine equipped with a nanofiltration membrane or a reverse osmosis membrane. Although the booster pumps produced by most booster pump manufacturers have the same structural mode, if the damping mounting plate is arranged at the bottom of the pump body, the inlet and the outlet with the internal thread connecting structure are respectively arranged at the left side and the right side of the pump body. The water inlet and the water outlet of the booster pump configured by the existing water purifier are connected with the hose through the water inlet connecting piece with the external thread and are connected in series in the filtering channel of the water purifier. The pump end of the water gap connecting piece is connected with the water inlet and the water outlet of the booster pump through a thread structure, and the pipe end of the water gap connecting piece is hermetically connected with the hose through an expansion pipe and a locking nut or is hermetically connected with the hose through a quick-plug connector. The three size factors of the position size of the mounting hole of the booster pump and the end face of the pump body, the distance between the mounting hole and the plane size of the side inlet and the plane size of the water outlet of the pump body and the height position size of the water inlet and the water outlet do not have any problem for the water purifier adopting a hose connection mode, and the hose is fixed on the water inlet and the water outlet of the booster pump through a water inlet connecting piece. At the moment, the water gap connecting piece is of a cantilever beam structure, and the extending pipe end is free from radial external force, so that the water gap connecting piece is simple in structure and convenient to use. However, the pump end external thread structure of the nozzle connecting piece only bears axial force and cannot generate bending deformation. When water purifier manufacturers consider adopting the rigid pipeline obtained by injection molding for improving the production and assembly efficiency and the assembly quality, overcoming the defects that the hose is easy to age and damage and the like, and adopt the rigid pipeline to be in sealing connection with the water inlet and the water outlet of the booster pump, the booster pumps of various manufacturers have different sizes in the three sizes, so that the three types of the rigid pipeline cannot be interchanged due to different geometric size parameters although the ranges of electrical parameters are consistent, the convention that the same outside protocol part of a whole machine manufacturer with huge yield can not meet the requirement of keeping three stock-in units by the same outside protocol part (controlling the cost of the outside protocol part, avoiding influencing the yield of the whole machine production due to the change of the outside protocol part and facilitating the maintenance of users) cannot be met, and when two ends of a water gap connecting part connected between the water inlet end and the water outlet end of the pump and the rigid pipeline in series are in rigid pipeline, the, The water outlet end adopts a common ninety-degree bent pipe mode or a straight pipe mode, and the stress state is poor: the tightness of the two ends is not easy to grasp, the sealing performance of the sealing contact surface is easy to reduce due to over tightness and over looseness, and particularly, the water outlet end of the pump has higher water pressure. Therefore, even if two of the three dimensions are the same and the other dimension is slightly different, it is difficult to ensure stable and perfect sealing connection between the booster pump and the rigid water inlet and outlet pipelines. In addition, for the user without the support of the after-sale service in the remote place, when the booster pump is damaged, the technical difficulty of replacing the pump and the pipeline connection is great, the self-operation is difficult, and because only one pump produced by one enterprise can be adopted, the booster pump with heavier quality needs to be mailed by a manufacturer or a distributor, the cost is high, and the problem of transportation damage is easy to occur. The defects and shortcomings seriously affect the improvement and promotion of the quality of the water purifier product and the popularization of the product.

Typically, the fastening assembly employs a screw and nut combination, and the nut is secured to the rigid conduit structure 3. A screw (not marked) passes through the position moving ring 2a on the position transition piece 2 and is fixedly connected with a nut on the rigid pipeline structure 3 to be connected in a threaded manner, so that rigid pipeline connection between the vertical cavity 1d of the water gap transition piece, the water passing pipeline 2d of the position transition piece and the water passing pipeline 3d of the rigid pipeline structure is realized. The position shifting ring 2a can only be moved around the screw within the range of its inner diameter, correspondingly shifting the horizontal position of the position transition piece 2 or of the movable transition piece.
When the booster pump is installed, an additionally arranged fastening component penetrates through an installation hole of the booster pump to fix the pump body on the base (or can be regarded as being fixed on the rigid pipeline structure 3) for coarse positioning so as to meet the requirements of the position size of the movable transition component and the end face of the pump body in the fixed horizontal direction. The screws are then screwed through the position-shifting ring 2a on the position transition piece 2 to the nuts on the rigid line structure 3 fixed to the machine base. Because the horizontal dimension between the water inlet and the water outlet of each booster pump and the pump body mounting hole is fixed, the concentric or eccentric state formed by the position moving ring 2a around the screw can meet the requirement of the contraposition connection and fixation of the water inlet and the water outlet of different booster pumps and the rigid pipeline structure 3 on the base. On this basis, the pump body and the position transition piece 2 are fastened respectively to be completely in place. Because the shock pad (not marked) that sets up around the booster pump body mounting hole and the sealing member 3b between position transition piece 2 and the rigid pipeline structure 3 of treating to connect all have elasticity, fasten pump body and the corresponding flexible of two sections pipeline length of the 2 in-process through the vertical direction of activity transition subassembly of position transition piece respectively, still be in sealed grafting state, consequently the booster pump advances, each junction between delivery port and the corresponding rigid pipeline structure all is in intact encapsulated situation, and only bear the water pressure effect in the pipeline of water passing, do not bear the radial external force effect of perpendicular to pipeline axis of water passing.
