Description
The utility model relates to a kind of spacing repairing formula diaphragm metering pump of quantitative conveying chemical industry slurries.
The hydraulic type diaphragm metering pump of domestic present production, wherein as Chinese Patent Gazette for Utility Models disclosed " plastics nesting type diaphragm metering pump hydraulic cylinder part (CN2053257U), its barrier film is planar, is clamped in both sides and is between the limiting board of cambered surface.When plunger is reciprocating, make the volume in oil pressure chamber and pressure produce pulsatile change, and be delivered on the barrier film by hydraulic oil, make its front and back agitate the purpose that reaches the suction medium.Said structure exists following deficiency: one. and will contact with pump fluid cylinder runner when medium is pumped, if adopt corrosion resistant metal, the cost of material height if adopt plastics, then can only be used for the lower occasion of working pressure.Two. must have some apertures (≤3 millimeters) to communicate between barrier film and the limiting board, it is big to make it flow resistance, and it is low to inhale journey.Three. there is the dead band between plate diaphragm and the limiting board, is unsuitable for carrying the two-phase fluid of particle.In sum, aspect conveying High Voltage corrosivity, high viscosity and easy precipitability medium, be difficult to satisfy its usage requirement, in addition, when the oil mass of protocnemes grease chamber causes deficiency because of packing leaking, generally recompensed by automatic Fill valve device, this device causes excessive repairing easily, thereby causes the early damage of barrier film.
The purpose of this utility model provides a kind of just in order to overcome above-mentioned the deficiencies in the prior art part can carry high pressure (can reach about 7.0MPa) deep-etching and high-viscous media and the easy two-phase fluid of precipitation effectively, and the spacing repairing tubular type diaphragm metering pump of the advantage of with low cost, reliable performance is arranged again.
The purpose of this utility model is to realize like this.That is: one. replace the planar barrier film by the straight tube barrier film, make fed sheet of a media be limit no resistive flowing in pipe, so both avoided medium to cylinder shape barrier film, make fed sheet of a media be limit no resistive flowing in pipe, so both avoided corrosion and the wearing and tearing of medium, also reduced flow resistance and the suction journey that has improved pump the cylinder body part.The straight tube barrier film can select for use the elastic material of different acid-alkali-corrosive-resistings to make, as acidproof glue ribbon, teflon, ABS plastic, to satisfy the anti-corrosion and wear-resisting requirement of fed sheet of a media.And,, do not have pressure difference therebetween, thereby have the advantage of discharge pressure height because the straight tube barrier film only plays a part to isolate fed sheet of a media and hydraulic oil in cylinder body.Two, adopt the technical measures of spacing repairing, thereby avoid generation, to guarantee straight tube barrier film normal working life because of automatic type recharging oil device excessive repairing causing barrier film early damage phenomenon.
Accompanying drawing is the structural representation of the spacing repairing tubular type of the utility model diaphragm metering pump.
Below with reference to accompanying drawing concrete structure of the present utility model and working condition are further described.
Referring to accompanying drawing, the spacing repairing tubular type of the utility model diaphragm metering pump, comprise valve seat, valve ball, valve gap, before, rear-bank rotor housing, bolt, Gland, stuffing nut and plunger, it is characterized in that: a stop collar 20 is housed in front-bank rotor housing 14, in stop collar 20, be embedded with a straight tube barrier film 16, on straight tube barrier film 16, following two ends, valve seat 13 is housed successively, valve ball 12, valve gap 11, pad 22, pipe 8, and link by pressing plate 9 and bolt 10 and front-bank rotor housing 14, at front-bank rotor housing 14 sidepieces guiding valve 18 and spring 17 are housed, before, rear- bank rotor housing 14,5 link by bolt 15, safety valve 7 and unidirectional Fill valve 6 pass through the screw thread direct connection on rear-bank rotor housing 5, following two ends, and plunger 1, filler 4, Gland 3 is contained in rear-bank rotor housing 5 center holes, stuffing nut 2 and rear-bank rotor housing 5 scyewed joint.The outer surface of positioning cylinder 17 is cylindrical, and internal surface is a sphere, and there is a hole that supplies guiding valve 18 to pass through at the middle part, and is evenly distributed with 5-30 aperture along circumference.
In the present embodiment, straight tube barrier film 16 usefulness acid-resisting rubbers folder fabric is made, 50 millimeters in pipe waist footpath, 132 millimeters of pipe ranges, 3 millimeters of wall thickness.Valve seat 13, valve gap 11 usefulness stainless steels are made, and valve ball 12 usefulness potteries are made, front and rear cylinder 14,5, and guiding valve 18 is all made with the QT600-02 material.
The utility model can fit on the transmission case 23 of common standard diaphragm metering pump and the controlling mechanism and use.Its working condition such as following.
It is reciprocating to order about plunger 1 by the power of transmission case 23 output, when plunger 1 is shifted to the dead point, back, forms a stroke in the oil pressure chamber 19 and holds the journey vacuum, under the atmospheric pressure effect, following unidirectional opening of valves, last closed check valve, straight tube barrier film 16 " expansion " medium is sucked in the pipe; When plunger 1 was shifted to preceding dead point, straight tube barrier film 16 was ' compressed ', and medium is extruded outside the pump, reached the purpose of suction medium.In addition, when the oil mass in the grease chamber 19 caused deficiency because of packing leaking, guiding valve 18 was pushed to the rear end by the straight tube barrier film of " expansion ", and grease chamber 19 is communicated with unidirectional Fill valve 6, under the atmospheric pressure effect, supplies oil mass.Along with plunger advancement, 16 compressions of straight tube barrier film, under the effect of spring 17, guiding valve 18 cuts out.When oil mass was sufficient, guiding valve 18 was in normally off, plays a part spacing repairing.
The utility model limit oil compensating tube diaphragm metric pump is compared with the ordinary flat diaphragm metering pump, and its major advantage is: one. and can carry two-phase fluid at interior various Korrosionsmediums clog-freely, enlarge the scope of application of pump; Two, be transferred medium and only in the straight tube barrier film, flow through, so other part material can adopt low-grade material to make, greatly reduce the manufacturing cost of pump; Three, the straight pipe type barrier film has the self-priming performance higher than dull and stereotyped barrier film; Four, adopt the technical measures of spacing repairing, the excessive deformation of control valve barrier film effectively is to guarantee its normal service life. So, the utlity model has the measuring accuracy height, inhale the journey height, the corrosion-proof wear performance is strong, and cost is low, and purposes is characteristics widely.
