Abstract

The utility model relates to a hydraulic extrusion capsule conveying pump, wherein, the hydraulic power of which is provided by a hydraulic pump station. The used medium is water or oil. A capsule which is sealed in a steel cylinder is extruded by the pressure of liquid, so the liquid is filled between the steel cylinder and the outer wall of the capsule, and a capsule cavity is used for sucking and discharging the conveyed fluid. When the pump station provides positive pressure, the capsule is extruded to be flat. Under the control of a valve, materials in the capsule are extruded and are discharged from a discharge pipe of the pump. When the pump station provides negative pressure, the liquid is pumped through a pressure water pipe. Under the control of the valve, liquid materials are sucked from a pump suction pipe, and the capsule is expanded. In this way, a working cycle is completed, and such alternate working completes the task of fluid conveying. In addition, the sealing performance of the pump and the pump cavity is good.

Description

Hydraulic pressure extruding capsule transfer pump

Technical field is a conveying equipment for fluid substances under the utility model---the pump class.Present domestic mechanical engineering manual, the big congruent books of pump class, and the pump of the various uses that domestic each producer produced all do not adopt hydraulic pressure to push the structural type of capsule.The purpose of this utility model is: utilize the structural type of hydraulic pressure (or air pressure) extruding capsule, and working principle.Produce small-sized closely concrete pump, because this small-sized closely concrete pump in building engineering construction equipment, still belongs to blank at present.According to this structural principle, can produce mortar pump again in addition, ore pulp pump, slurry pump and carry the transfer pump of sour alkali solution.

Of the present utility model the contents are as follows described:

The utility model is in the container of sealing---steel cylinder, (Figure of description---3) rubber bag tank of device (accompanying drawing---4).Rubber bag tank is made the both ends open type, and is contained on discharge tube and the suction pipe that (accompanying drawing-2-6), pipe becomes one with end flange, and flange connects by the screw thread steel cylinder, and uses sealer to be sealed.Discharge tube and suction pipe and pump outlet valve door (accompanying drawing---1), the pump inlet valve door (accompanying drawing---7) link together, when expulsion valve is opened, suction valve closure, press water is pressed into pump chamber from penstock (accompanying drawing---8), capsule is subjected to the pressure effect of water by crowded flat, and the fluid foods of capsule (accompanying drawing---5), be discharged to the pump chamber outside by discharge tube.When discharge valve is closed condition, suction valve allows when being opening state, and press water is extracted out from penstock by hydraulic power unit, forms vacuum in the pump chamber, and capsule is under the external atmospheric pressure effect, and a work cycle has so just been finished in expansion, and suck fluid foods.The working method of just utilizing the pressure of liquid to push capsule is finished the work cycle of pump and the task of conveyance fluid.Press water of this pump or pressure oil are to be supplied with by hydraulic power unit.The standardization of liquid pump station, seriation can be purchased as required.

The utility model compared with prior art has following advantage:

1, this pump, the pump chamber good seal performance, fricton-tight sealing improves seal durability, makes degree of vacuum raising in the pump chamber, sucks effective.

2, this pump structure makes the runner of fluid more unobstructed, sucks runner and discharges linearly type of runner, and suitable conveying contains particle, the fluid that abrasiveness is strong, or carry the fluid of the mobile difference of thickness.

3, can carry acid, alkali, salt etc. to have corrosive fluid.

4, this pump adopts hydraulic pressure extruding capsule mode to come conveyance fluid, is worked under isobaric condition in each working position of capsule, and the stress distribution that acts on the capsule is even, has avoided the local generation of capsule heavy wear, and this has just prolonged the working life of pump.

What 5, this pump can be as vacuum pump is a kind of, and can omit carbonated drink, oily steum separating device.The utility model Figure of description literal note (figure one)

What accompanying drawing was represented is this pump work principle schematic, and the pump chamber sectional drawing drawn of chi in proportion.

1----discharge valve

2---pump discharge line

3---steel cylinder

4---capsule

5---the material that is transferred
