Abstract
A feeding pipe for a diaphragm pump relates to the improvement of the structure of a feeding pipe of a three-cylinder single-action diaphragm pump. The utility model provides the feeding pipe for the diaphragm pump, which is simple in structure and stable in pressure, and slurry deposition and valve clamping phenomena are unlikely to happen. The feeding pipe comprises three tees which are connected in series through straight pipes, two ends of each straight pipe are sealed, and the feeding pipe is characterized in that two separation parts of the three tees are respectively provided with a feeding port. The two feeding ports are respectively provided with an elbow; the two elbows are arranged oppositely and are connected with a feeding end compensator.
Description
Technical field
The utility model relates to a kind of improvement of three cylinder single-acting membrane pump feeding tubular constructions.
Background technique
Supply pipe is positioned at the fluid end of three cylinder single-acting diaphragm pumps, and its structure is mainly comprised of parts such as straight tube, threeway, adpting flange and end caps (blind flange).In membrane pump fluid end, supply pipe is connected with charging clack box, plays the effect of input slip in diaphragm pump running.In addition,, according to the different requirements of carrying the characteristic of slip and flow, pressure, the latus rectum of supply pipe also changes thereupon.Due to the structure of supply pipe, to input slip, the flowing state in pipe plays conclusive effect, and there is interface in supply pipe and charging clack box, therefore, reasonably feed pipe structure is the key factor that affects diaphragm pump safety, stable operation and user's field failure rate.
Conventional diaphragm pump feed pipe structure as shown in Figure 3, adopts the input slip mode of one-sided charging, cecum compensator 7 and feed end compensator 8 is installed respectively with the flow pulsation in balance tube in supply pipe both sides.But the conveying for high viscosity, large particle degree slurry still easily produces slip deposition in pipe, and then cause charging clack box easily to produce card valve phenomenon, not only make diaphragm pump continuous operation rate reduce, and have shortcomings such as causing in charging clack box the reduction of easily damaged parts life-span because slurry fluidised form in supply pipe is uneven.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of simple in structure, and pressure stability is difficult for occurring slip deposition and blocks the membrane pump feeding pipe of valve phenomenon.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises three threeways that are chained together by straight tube, and the closed at both ends setting of straight tube, is characterized in that: two intervals of three threeways are provided with material feeding mouth.
As a kind of preferred version of the present utility model, on described two material feeding mouths, be provided with elbow; Two elbows are oppositely arranged and are connected with a feed end compensator.
The beneficial effects of the utility model: 1, the utility model adopts the bilateral charging of middle part branch, flow and the pressure of each charging clack box of active balance, reduce the possibility that card valve phenomenon occurs, and improved the continuous operation rate of diaphragm pump at user scene.
2, the utility model can effectively reduce the generation of the inner slip depositional phenomenon of supply pipe, thereby has improved the working life of the inner easily damaged parts of charging clack box.
3, the utility model will be provided with elbow on two material feeding mouths, and the same feed end compensator of two elbows is connected, and its fluid end only needs to adopt a feeding compensator to get final product flow pulsation in balance tube, has reduced manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the structural representation of existing membrane pump feeding pipe.
In accompanying drawing, 1 is that blind flange, 2 is that straight tube, 3 is that threeway, 4 is that material feeding mouth, 5 is that elbow, 6 is that interval, 7 is that cecum compensator of the prior art, 8 is feed end compensator of the prior art.
Embodiment
The utility model comprises three threeways 3 that are chained together by straight tube 2, and the closed at both ends setting of straight tube 2, is characterized in that: 6 places, two intervals of three threeways 3 are provided with material feeding mouth 4.
As a kind of preferred version of the present utility model, on described two material feeding mouths 4, be provided with elbow 5; Two elbows 5 are oppositely arranged and are connected with a feed end compensator (not shown).
The two ends of described straight tube 2 are sealed by blind flange 1.
When the utility model is used, slip is from the feed end compensator input of two elbows 5, thus the charging of formation bilateral, and supply pipe two ends adopt blind flange 1 to connect.The utility model not only can effectively improve the flowing state of input slip in pipe, effectively prevents slip deposition, and can reduce the number of feed rate compensation device, has reduced the manufacturing cost of diaphragm pump.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
Claims (3)
1. a membrane pump feeding pipe, comprises three threeways (3) that are chained together by straight tube (2), and the closed at both ends setting of straight tube (2), is characterized in that: material feeding mouth (4) is located to be provided with in two intervals (6) of three threeways (3).
2. a kind of membrane pump feeding pipe according to claim 1, is characterized in that: on described two material feeding mouths (4), be provided with elbow (5); Two elbows (5) are oppositely arranged and are connected with a feed end compensator.
