The utility model discloses simple structure can improve the stability of whole equipment operation.
Description
Technical field
The utility model relates to a kind of intermediate membrane pump with pneumatic drive from upper end air inlet.
Background technique
Membrane pump with pneumatic drive is a kind of novel liquid material transfer equipment, the use of the equipment such as alternative submersible pump, pollution discharge pump, centrifugal pump.Little for volume, lightweight, the easy to install feature such as flexibly of this pump.Because it can carry solids-laden fluid, there is not the advantages such as the problem of explosion-proof aspect, generally use in the increasing industry such as petrochemical industry, coating, boats and ships, water treatment, food, papermaking, mine.
Originally the middleware of membrane pump with pneumatic drive itself is provided with gas source air inlet, as shown in Figure 1, this intermediate not only processes trouble, because gas source air inlet passage is directly facing to the middle and lower part of reverser (as shown in Figure 2), reverser is had to the active force of a side, and the working state of diaphragm pump is both sides alternations, have vibration in the course of the work, and reverser pts wt is very light, have the situation of beating in the process to occur, when reverser takeoff leave air guide block time, gas turnover direction and air inflow can be affected, thus the working efficiency of diaphragm pump is affected, in the occasion that some is extreme, cause piston is come off from its bayonet socket because reverser leaves air guide block (as shown in Figure 3) at the volley, and there is the fault of equipment downtime, unnecessary loss can be caused to user, and employing aluminum alloy material, in use run into and have acid, during the occasions such as alkali, intermediate subjects to the erosion of harmful matter in environment.
Model utility content
In order to solve the problems referred to above that prior art exists, the purpose of this utility model is the intermediate membrane pump with pneumatic drive proposing the air inlet of a kind of upper end, and structure is simple, can improve the stability that whole equipment runs.
For achieving the above object, the utility model is solved by following technological scheme:
A kind of intermediate membrane pump with pneumatic drive from upper end air inlet, comprise intermediate, be fixed on the air guide block bottom intermediate air chamber, be placed on the reverser in described air guide block, the two ends that one left piston and a right piston are separately fixed at described reverser drive described reverser to horizontally slip, also comprise the air valve cap that is fixed on described intermediate top, this air valve cap is provided with gas source inlet.
As preferred technological scheme:
Membrane pump with pneumatic drive described in the utility model, described air valve cap comprises valve gap body, one end of described valve gap body transverse direction is provided with gas source inlet, in described valve gap body, a filter member coupling is fixed on described gas source inlet, and the described vertical bottom of valve gap body is evenly provided with the gas-entered passageway that some and described filter member communicates.
Membrane pump with pneumatic drive described in the utility model, the airintake direction of described gas-entered passageway and the airintake direction of described gas source inlet orthogonal.
Membrane pump with pneumatic drive described in the utility model, described gas source inlet is pipe thread G1/2 ".
Membrane pump with pneumatic drive described in the utility model, described gas-entered passageway is 3 or 4 roads.
Membrane pump with pneumatic drive described in the utility model, the bayonet socket at the draw-in groove that described left piston, right piston are respectively equipped with and described reverser two ends is connected and fixed.
Membrane pump with pneumatic drive described in the utility model, described air guide block is steel plate, is provided with exhaust port and is positioned at the left through hole on described exhaust port both sides and right through hole.
Membrane pump with pneumatic drive described in the utility model, described air guide block is screwed in bottom described intermediate air chamber.
Owing to adopting above technological scheme, compared with prior art, the intermediate membrane pump with pneumatic drive of a kind of upper end air inlet of the present utility model, structure is simple, can reduce costs, pressurized air is that even (having 3,4 gas-entered passageways) enters air chamber from upper end, and has one to the active force pressed down to reverser, ensure that reverser can not leave air guide block, the stability that whole equipment runs can be improved.

Embodiment
Below with reference to the accompanying drawings and embodiment, the utility model is described in further detail:
As shown in Figure 4, a kind of intermediate membrane pump with pneumatic drive from upper end air inlet, comprise intermediate 1 (as shown in Figure 6), be screwed in the air guide block 2 bottom intermediate 1 air chamber, be placed on the reverser 3 in air guide block 2, left, the fluting that right piston 4 is provided with is separately fixed at the bayonet socket at reverser 3 two ends thus drives reverser 3 to horizontally slip, also comprise one and be fixed on intermediate top and the air valve cap 6 sealed with gasket seal 5, this air valve cap is provided with gas source inlet D, intermediate 1 of the present utility model does not have suction port, source of the gas enters from the gas source inlet D of air valve cap.This air guide block 2 is steel plate, is provided with exhaust port and is positioned at the left through hole on exhaust port both sides and right through hole.The utility model intermediate adopts built-in structure, by air guide block 2, reverser 3, be placed in intermediate air chamber, and connect distributing valve piston respectively by ventilation switch 3 left and right sides, by the motion of piston, drive reverser 3 to swing, switch the passage of turnover air chamber, enable pressurized air alternately enter rubber membrane room, left and right, make pneumatic diaphragm pump work.
As shown in Figure 5, air valve cap comprises valve gap body 7, one end of valve gap body 7 transverse direction is provided with gas source inlet, and in valve gap body 7, filter member 8 coupling is fixed on gas source inlet D, and the vertical bottom of valve gap body 7 is evenly provided with some gas-entered passageway A, B, C of communicating with filter member 8.
