Abstract
A plunger water pump with light dead weight and high water flow due to two water inlet-outlet channels is composed of a main cylinder, two sub-cylinders symmetrically arranged on the top of main cylinder in V-letter mode, a crankshaft in said main cylinder and with 2-6 crank arms, and several connecting rods (two for each crank arm).
Description
Technical field the present invention relates to a kind of plunger pump.
Background technique is present, plunger pump has a variety of, wherein the plunger pump that performance is better be on June 8th, 2005 utility model patent communique disclosed a kind of＜four novel cylinder energy-saving water pumps (patent No. 2004200513095) its structure mainly is: have and establish a part in the piston casing of case lid and be positioned at bent axle outside the case, its each connecting lever is provided with the connecting rod with its flexible connection, the piston of the other end of each connecting rod and guide piston bar flexibly connects, and this guide piston bar passes the black box in the piston cylinder respectively, the suction chamber housing, top is arranged in the circular groove shape plunger of the pump housing.The diameter shrinkage part of this guide piston bar passes at the bottom of the central through bore of plunger slot and the shaft shoulder and the plunger slot adjacent, except that central through bore, also is provided with drainage hole at the bottom of the plunger slot.Reach the outer guide piston bar of plunger and be provided with into water assembly, a side and suction chamber are with the pump housing that is fixed on the piston casing, and its opposite side links to each other with pump cover.The side is provided with in the pump cover of drain opening and is provided with out water assembly.Although this pump has many advantages, also have some deficiency: 1 if augmented flow just needs to increase the quantity of piston cylinder.And the water pump of this structure can only be that a plurality of cylinders are in one line side by side.Doing so not only that floor space is big, self heavy, more mainly is that resistance of water drainage is big, and the motor energy dissipation is serious.2, it has only an intake tunnel and a drainage channel, if fault will directly cause entire pump to advance impeded drainage, gently then influences normal operation, and is heavy then need shut down repairing, brings loss to the user.
Summary of the invention the object of the present invention is to provide that a kind of flow is big, resistance of water drainage is little, power consumption less and have two advance, the plunger water pump of drainage channel.
Piston casing of the present invention is made up of a main box body and two branch casings.Wherein be similar on the main box body that is box-shaped and establish opening, which is provided with the piston case lid.Be provided with two coupled logical branch casings on main box body top, these two is between the branch casing of symmetry certain angle to be arranged with the center line, preferably less than 90 °.Be provided with bent axle in main box body, the one end passes the supporting member of main box body one side, and this is positioned at the outer part of case and can links to each other with motor.This horizontally disposed bent axle can be established 2-6 connecting lever, establishes two connecting rods that flexibly connect with bent axle on each connecting lever, and the other end of this two connecting rod lays respectively in the piston cylinder of two branch casings.And be positioned at all connecting rods of two branch casing piston cylinders, the piston flexible connection of all the same and each self-corresponding guide piston bar lower end, its upper end with prior art.Be preferably in and be provided with in the piston cylinder that outer circumferential face is attached on its inwall, the corresponding lining in interior cross section and the outer cross section of piston, it can increase the working life of pump.Above-mentioned guide piston bar passes black box that is located in the piston cylinder and the suction chamber housing that divides the casing upper end, and top is positioned at the pump housing.The bottom is provided with black box corresponding with plunger and the gland that is connected that links to each other with suction chamber in this pump housing.Above-mentioned guide piston bar top places the downward circular groove shape plunger of pump housing inner opening, and guide piston bar diameter shrinkage part passes the central through bore of plunger head, and the shaft shoulder is adjacent with the plunger top.This plunger top also is provided with drainage hole except that establishing central through bore.Reach the outer guide piston bar of plunger and be provided with the water inlet assembly of forming by guiding gland, water inlet valve block, locking plate, round nut, spring, the water inlet path that this water inlet assembly control is made of intake pipe, suction chamber, the pump housing and plunger.With its lower end and the same cylindrical shape pump housing that is fixed on the branch casing of suction chamber, the upper end links to each other with the circular groove shape pump cover that Open Side Down by the bolt that passes the suction chamber housing, and drain opening is established in this pump cover side.In pump cover, be provided with by what gland, water outlet valve seat, water outlet spool, limited post, spring and Sealing were formed and go out water assembly.
Working procedure of the present invention is: when bent axle rotated, the plunger that drives all guide piston bars in two branch casings and be located at its upper end by connecting rod was in the to-and-fro motion of pump housing endosome.Two connecting rods on each crank throw are synchronized with the movement guide piston bar that is positioned at two branch casing piston cylinders and the plunger that is attached thereto.Usually under the state, the spool of pump cover internal drainage assembly with the sealing of valve seat osculum, makes valve closing under spring action.When plunger moves downward, form vacuum in the pump housing, make the valve block of the water inlet assembly of plunger upper part leave the through hole that plunger pushes up, meanwhile, the outer water of pump enters in the pump housing by intake pipe, suction chamber, plunger under suction function.When plunger moves upward, the valve block of water inlet assembly under the resistance combined effect of Returnning spring and water with through hole sealing on the plunger top, and the spool that goes out water assembly is upwards pushed away under the pressure of water, the osculum of lifting off a seat, valve is opened, water in the pump is advanced in the pump cover, again by outside the drain opening excavationg pump on the pump cover.Because plunger is ceaselessly done periodic to-and-fro motion in the pump housing, just water (or other liquid) can be transported to eminence by lower.
The present invention has following advantage compared to existing technology.
1, the present invention adopts the V-arrangement split to arrange, symmetry increases the working room increases flow, it than traditional plunger pump adopt coaxial line mode in one line save floor occupying area, from heavy and light, two the drainage channel water displacement is big, resistance of water drainage is little, energy consumption of electrical machinery is few.
2, two advance, drainage channel, if a passage breaks down, another passage can work on, and does not influence normal draining, can not bring direct loss to the user.
3, the power consumption correlation data of plunger pump of the present invention and other pump is as follows:
Condition: 40 tons of flows, 400 meters of lifts
| Project | Centrifugal pump | Six cylinders, one line plunger pump | Six cylinder V-arrangement plunger pumps |
| Two step water lifts | One step water lift | One step water lift | |
| Motor institute wasted work rate | 74 kilowatts/hour | 55 kilowatts/hour | 37 kilowatts/hour |
The present invention is more energy-conservation 50% than the centrifugal pump of prior art as can be seen from the above table, than six cylinders, the one line plunger pump energy-conservation 32% of prior art.
4, long product lifecycle of the present invention.
5, product noise of the present invention is little.
