Description
Technical field
The utility model relates to hydraulic diaphragm metering pump, particularly a kind of tubular type diaphragm metering pump fluid end structure of designs simplification.
Background technique
But hydraulic diaphragm metering pump is because of the flow step-less adjustment, and measuring accuracy is high, and good airproof performance is used widely without characteristics such as leakages.Conventional hydraulic diaphragm pump diaphragm shapes is circular tabular barrier film, is called for short board-like film, and its working principle is that hydraulic oil promotes the diaphragm flex motion, changes the media cavity volume size, constantly promotes medium and does directed output.But it is bent assorted that the weakness of board-like film metering pump is flow channel for liquids, and circulating resistance is large, is not suitable for transfer of highly viscous and with the underflow liquid of a certain amount of particle.
At present, high viscosity liquid is carried mainly take gear pump, screw pump as main, but it has drawback clearly: measuring accuracy is low, and rate of fault is high.
For adapting to this working condition, the tubular type diaphragm pump arises at the historic moment.But according to investigation, tubular type diaphragm pump utilization rate is extremely low, and main cause has 2 points: 1, manufacturer is few.2, complex structure, cost is high.Reach product as example take U.S.'s Paasche phenanthrene, its structure is on the board-like barrier film fluid end of hydraulic pressure basis, stack tubular type barrier film pump head and forming, and this just causes complex structure, and cost is high, is difficult to popularize.

A kind of tubular type diaphragm metering pump fluid end structure of designs simplification is provided, comprise cylinder body, pump head, barrier film, import one-way valve and outlet one-way valve, the side of pump head is provided with the hole for the hydraulic oil circulation, described pump head has the hydraulic pressure cavity of the little spindle hollow broad in the middle in two, described barrier film is the tubular type barrier film, turning up in its two ends, and realizes fixing by end cap flange and pump head clamping.
As further improvement, the two ends of the pump head at described end cap flange place are provided with the ladder counterbore, and the position of turning up in described tubular type barrier film two ends is positioned at the ladder counterbore.
As further improvement, described pump head links to each other with the cylinder body at plunger place.
As further improvement, described import one-way valve and outlet one-way valve are divided on two end cap flanges.
As further improvement, described import one-way valve and outlet one-way valve are connected to two end cap flanges by pipeline respectively.
As further improvement, described end cap flange links to each other with pump head by bolt.
As further improvement, described pump head has columniform external shape.
As further improvement, the described pump head up and down side at position is respectively equipped with a radially screw that is communicated with hydraulic pressure cavity, and top radially screw and two valve group seats are spirally connected, and following radially screw and Fill valve are spirally connected; Two valve group seats and Fill valve all are connected to oil sump by pipeline.
Compared with prior art, the beneficial effects of the utility model are:
1, simple in structure, good manufacturability, convenient for installation and maintenance.
2, production, operating cost are low.

Reference character among the figure is: 1 oil sump; 2 Fill valves; 3 plungers; 4 gland nuts; 5 cylinder bodies; 6 connected bodies; 7 two valve group seats; 8 two valve groups; 9 outlet one-way valves; 10 bolts; 11 end cap flanges; 12 hydraulic pressure cavity; 13 media cavity; 14 tubular type barrier films; 15 pump heads; 16 import one-way valves.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Among Fig. 1, the tubular type diaphragm metering pump fluid end structure of designs simplification comprises cylinder body 5, pump head 15, barrier film 14, import one-way valve 16 and outlet one-way valve 9, and described barrier film is tubular type barrier film 14; Described pump head 15 is outside cylindrical, and pump head 15 inner chambers have through hole, and through hole is spindle, and the through hole two ends are provided with the ladder counterbore, the tubular type barrier film 14 of packing into movingly successively, end cap flange 11, and is connected and fixed with bolt 10.Import one-way valve 16 and outlet one-way valve 9 are spirally connected respectively on the end cap flange 11 at described pump head 15 two ends.Tubular type barrier film 14 is divided into hydraulic pressure cavity 12 and media cavity 13 with through hole, and media cavity 13 is used for fed sheet of a media, and tubular type barrier film 14 can be avoided leakage and the pollution of medium with fed sheet of a media and hydraulic oil isolation.Tubular diaphragm 14 bores are large, inner wall smooth, and with import one-way valve 16, the outlet one-way valve 9 at same axis, flow channel for liquids is unimpeded, without the dead angle, suitable transport viscosity is higher, or contains the liquid of a certain amount of particle.
Described pump head 15 external upper have a radially screw, and screw is communicated with pump head 15 hydraulic pressure cavity 12, and the two valve group seats 7 that are spirally connected.Two valve group seats, 7 connections, two valve groups 8 when hydraulic pressure cavity 12 hydraulic oil superpressure, can be discharged pressure releases immediately by two valve groups 8, by the air in two valve groups, the 8 all right in time eliminating hydraulic pressure cavity 12, guarantee the pump measuring accuracy in addition.
Described pump head 15 outer lower side have a radially screw, and screw is communicated with pump head 15 hydraulic pressure cavity 12, and the Fill valve 2 that is spirally connected and is communicated with oil sump 1.Fill valve 2 can replenish hydraulic pressure cavity 12 interior damaged hydraulic oil.
