Abstract

The utility model relates to a triple discharge pump, which comprises a solid hard type combination of diaphragm elements, a swinging element and a lower cover frame. The combination is combined by piston elements and diaphragms, the inner part of the diaphragms comprises a convolute, a fixed sealing element and an assembling mechanism, and the elements are combined into a single element. The assembling mechanism and the swing element can be fixed together directly, and thereby, the assembling is easy, and the utility model has better reliability and operational performance. When a reverse osmosis principle is used, maintenance times can be reduced, the utility model has higher reliability, the structure of the single element is not provided with holes, continuity is better, and thereby, material tired phenomenon can be prevented from generation.

Description

Triple emptying pumps

The utility model relates to a kind of triple emptying pump, refers to a kind of triple emptying pumps with the motivational drive part that is combined into one especially.

See also shown in Figure 1, existing triple emptying pumps include a complete pump head 1, switch combination 2, piston 3, safety check 3a, non-control strip 3b, on cover frame 4, bypass valve combination 5a, non-bypass valve combination 5b, diaphragm 6, swing part 7 and motor 8.As seen, the assembly element of existing triple emptying pumps is various, particularly piston 3 must utilize the screw that is passed by diaphragm 6 and following cover frame 4 to combine with this swing part 7 and constitute a built-up section, therefore maintain time-consuming effort, motivational drive part wherein, as shown in Figure 2, promptly piston, diaphragm, to cover frame, swing part etc. down be the cardiac component of these triple emptying pumps, it is the main determining factor of operating efficiency and power consumption.

The purpose of this utility model is to provide a kind of triple emptying pump, and its motivational drive partly adopts integrated mode to constitute, and simplified structure is convenient to maintaining.

The purpose of this utility model is to realize like this, a kind of triple emptying pump promptly is provided, it comprise complete pump head, switch combination, safety check combination, non-control strip, on cover frame, bypass valve combination, non-bypass valve combination, piston piece, diaphragm, cover frame, swing part and motor down; Described piston piece and diaphragm are with solid rigid one-body molded making, be provided with mounting mechanism in the described diaphragm in addition, described cover frame down and described diaphragm and piston piece are bonded into single element with means of fixation, described swing part combines with integrated piston piece and diaphragm in the engaging mode, and the described frame of cover down is fixed between the two; Described diaphragm is provided with convolute and fixing seal element.

The advantage of the utility model device is that simple in structure, maintaining is convenient.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is the three-dimensional exploded view of existing triple emptying pumps;

Fig. 2 is the motivational drive cross-sectional view taken of existing triple emptying pumps;

Fig. 3 is a three-dimensional exploded view of the present utility model;

Fig. 4 is a motivational drive cross-sectional view taken of the present utility model;

Fig. 5 is the constitutional diagram of motivational drive part of the present utility model;

Fig. 6 is the sectional drawing of motivational drive part of the present utility model.

See also Fig. 3,4, the motivational drive of the triple emptying pumps of the utility model partly comprises by piston piece 16a and the integrated solid rigid diaphragm part combination 16 of diaphragm, covers frame 15 and swing part 17 down, and said elements is bonded into single overall structure.This motivational drive part with after motor 18 combines again with a non-bypath valve group 15b, a bypass valve sets 15a, on cover frame 14, safety check 13a, non-control strip 13b, switch combination 12, pump head 11 etc. and further be combined into the triple emptying pumps of the utility model.

This piston 16a and diaphragm are one solid and with one-body molded mode be combined into, and this time cover frame 15 and this diaphragm part combination 16 fixing single structures that form wherein are provided with the mounting mechanism 16b that installs and fixes usefulness.This swing part 17 snaps into one with this mounting mechanism 16b, and therefore, motivational drive part of the present utility model can combine or separate with motor 18 easily, and this is an improvement greatly for the manufacturing of triple emptying pumps and installation, maintenance service.So exempted the inconvenience of dismounting screw and piston, and needn't add the top edge sealed groove behind at diaphragm.

The solid rigid diaphragm part combination 16 of this one comprises piston piece 16a, convolute, fixing Sealing and mounting mechanism 16b, its with the sealing effect that can keep pumping chamber after swing part 17 combines.

In order to cooperate above-mentioned diaphragm structure, mask part was revised under the swing part of these triple emptying pumps reached, and this modification can make this mounting mechanism directly insert in this swing part.In addition, this time cover frame is modified to and can adapts to the variation that becomes the spiral fashion so diaphragm from the ramp type diaphragm, this mainly be because down the face that connects that engages with the diaphragm convolute of cover frame with and and the cause that connects the relation change between the face of swing part.

The utility model makes swing part and diaphragm with the most important meaning of manner combination into, make the mounting type and the overall structure external form thereof of two elements that significant variation arranged, just convenient when making the mounting mechanism operation like this as adopting a screw to make up, only need to use suitable strength to get final product, operating characteristics and manufacture cost can be lowered widely.

Certainly to reach above-mentioned these purposes, at first will develop suitable material and understand which combination and can reach predetermined target.This time cover frame 15 and swing part 17 must be made with long fibre type nylon material or identical materials.The material of this diaphragm must adopt the Santoprene of suitable Shore hardness, or acceptable alternative.The necessary processing stress that can be suitable of selected material makes and gets off can not reduce operating characteristics for a long time or its consumed energy is increased.
