The present invention provides a pump, which comprises a pump body, a transmission part and a part for conveying fluid media and is characterized in that the pump body is composed of a high pressure water storage tank, a low pressure water storage tank, two main boards and two side boards. A plurality of double arranged double cavity connecting bags forming the part for conveying fluid media are arranged at both sides of the high pressure water storage tank and the low pressure water storage tank, and are communicated with the high pressure water storage tank and the low pressure water storage tank through a high pressure valve and a low pressure valve positioned in a high pressure valve chamber and a low pressure valve chamber. A bearing, a main shaft, a cam and a pressure support forming the transmission part are arranged on the two side boards.

Description

A plurality of double-cavity conjoined capsule type high flow leakproof pumps

Technical field

The present invention relates to a kind of high flow leakproof pump that utilizes a plurality of double-cavity conjoined capsule volume-variation suctions or extrude fluid.

Background technique

It is 4 fixed that the current all kinds of pumps that use both at home and abroad, most gears, blades etc. of adopting, each pump all have, and A, decide revolution, and B, flow setting type, decide lift at C, and D, constant volume all are immutable in production and use.

In the use of conventional pump, most is that transport portion and drive part are one, and service time one is long, and tightness descends rapidly, fluid begins to external leakage, make gear, blade, serious being corroded of bearing, it is more serious to damage very big, particularly sour, alkaline flowing medium corrosion, function extremely descends, and even scrap fully, not only influence is produced, also befouling environment.

Current corrosion protection pump majority is selected stainless steel material for use, shortcomings such as difficulty of processing is big, power consumption is big, cost is high, anticorrosion poor, easy leakage, life-span weak point.

Summary of the invention

In order to overcome and root out the shortcoming and defect of above-mentioned all kinds of pumps completely, the present invention proposes a kind of high flow leakproof pump, it comprises the pump housing, drive part and conveyance fluid medium part, it is characterized in that the pump housing is by the high pressure water storage box, the low pressure water storage box, two mainboards, two blocks of side plates are formed, the a plurality of double-cavity conjoined capsules that constitute the double row of conveyance fluid medium part are installed in high pressure water storage box and low pressure water storage box both sides and are communicated with the bearing of formation drive part with high pressure water storage box and low pressure water storage box fluid by being positioned at indoor and indoor high pressure valve and the low pressure valve of low pressure valve of high pressure valve, main shaft, cam and pressure arm are installed on two blocks of side plates.

The invention has the advantages that, one, transport portion and drive part is well-separated, like this main shaft of drive part and bearing can not be etched again, can not be impaired, thereby improved working life.

They are two years old, gear, the blade of tradition part are replaced with double-cavity conjoined capsule, the interface at double-cavity conjoined capsule two ends is connected with the high pressure valve chamber with the low pressure valve chamber, between them, form the passage of a sealing, loosen the formation vacuum by double-cavity conjoined capsule, low pressure water storage box fluid is sucked in the capsule, when double-cavity conjoined capsule shrinks, again the fluid in the capsule is discharged from liquid outlet through the high pressure water storage box.

They are three years old, in order to satisfy requirement to flow and lift, design and applying high voltage water storage box and low pressure water storage box achieve the goal cleverly, load onto a plurality of double-cavity conjoined capsules of two rows by the both sides of high pressure water storage box and low pressure water storage box and reach big flow, high-lift purpose, according to the user require can assemble the requirement that double-cavity conjoined capsules such as 2,4,6,8,10,12 satisfy the each side user in the pump housing.

Its four, can be by adjusting the number of times that motor speed changes extruding double-cavity conjoined capsule in the unit time, thus adjust lift of pump and flow.

Description of drawings

Fig. 1 is the plan view of pump,

Fig. 2 is the side view of pump.

The mark implication is as follows among the figure: the 1-liquid outlet, 2-high pressure retaining case lid, 3-high pressure valve chamber cap, 4-high pressure valve chamber, the 5-high pressure valve, the 6-clip, 7-high pressure water storage box, the 8-mainboard, the 9-bearing, the 10-guide wheel, the 11-guide wheel shaft, the 12-double-cavity conjoined capsule, the 13-pressure arm, the 14-cam, the 15-main shaft, the 16-bearing cap, 17-low pressure water storage box, 18-low pressure valve chamber, the 19-low pressure valve, the 20-liquid entering hole, 21-low pressure valve chamber cap, 22-low pressure retaining case lid, the 23-base, the 24-bearing, the 25-side plate.

Embodiment

Referring to Fig. 1, this pump housing is by high pressure water storage box 7, low pressure water storage box 17, two mainboards 8, two blocks of side plates 25 are formed, main shaft 15 is arranged on the biside plate 25 by bearing 9 and 24, five cams 14 are installed on the main shaft 15, main shaft 15 link to each other with-3.2KW motor (not shown) and under the driving of motor round the center rotation of

bearing

9 and 24, thereby driving each cam 14 rotates, make each cam 14 drive corresponding pressure arm 13 respectively and do straight reciprocating motion, thereby make each pressure arm 13 push opposite two rows ten double-cavity conjoined capsules 12 in parallel repeatedly, the two-port of each double-cavity conjoined capsule 12 connects high pressure valve chamber 4 and low pressure valve chamber 18 respectively, make high pressure valve 5 and low pressure valve 19 alternately open and shut, when high pressure valve 5 is opened, low pressure valve 19 is shut, block fluid enters in the capsule, force the fluid in the capsule to pass through high pressure valve chamber 4, high pressure water storage box 7 is discharged through liquid outlet 1, otherwise, high pressure valve 5 is shut, block fluid flows out, under the effect of pull of vacuum, open simultaneously low pressure valve 19, low pressure valve chamber 18, the fluid of low pressure water storage box 17 sucks in the capsule, push away extruding and pressure release repeatedly, suction repeatedly and discharge fluid once more.

The working procedure of concrete said structure pump is as follows:

Under the driving of motor, the main shaft 15 that is connected as a single entity, cam 14 one common peripheral are around the center rotation of the bearing on the side plate 25 9 and 24, when cam 14 turns to maximum radius, push double-cavity conjoined capsule 12 simultaneously by pressure arm 13, the volume of double-cavity conjoined capsule 12 is dwindled, pressure by the fluid transmission makes low pressure valve 19 that low pressure valve chamber 4 is shut, the blocking-up feed pathway, the pressure that transmits by fluid simultaneously, high pressure valve is opened, pump pressure goes out the fluid of double-cavity conjoined capsule 12, otherwise, when double-cavity conjoined capsule 12 is in the pressure release diastole state, the volume of double-cavity conjoined capsule 12 increases, in capsule under the effect of pull of vacuum, shut high pressure valve 5, blocking-up capsule inner fluid flows out, and under the effect of pull of vacuum, opens low pressure valve 19, will be from low pressure valve chamber 18, the flowing medium of low pressure water storage box 17, suction also is full of 12 li of double-cavity conjoined capsules, main shaft 15, the arrival of Next cam 14 maximum radius is waited in the rotation that cam 14 continues, realize next extruding and pressure release, the dwindling and increase of capsule volume, the suction of flowing medium and the process of discharge are finished the purpose of conveyance fluid medium.

This pump can change the size of flow, the height of lift arbitrarily under the situation that does not change main body, reach the development of a machine one multifunction.
