Description

Four novel cylinder energy-saving water pumps

Technical field

The utility model belongs to and has high-lift, big flow, the plunger water pump equipment of multi-cylinder, particularly a kind of four novel cylinder energy-saving water pumps.

Background technique

At present, make the confession that hoists of the water of lower, row's engineering, as: the lifting of the tunnel water in mine, the discharge of phreatic water, the irrigation of agricultural terraced fields, the engineering of drawing water up a hill, the fire fighting supply of urban skyscraper thing,------is extensive use of plunger water pump in the high pressure water injection in oil field, be generally a piston cylinder, it comprises the pump housing, pump cover, bent axle, connecting rod, piston, plunger, advance, the water outlet valve port, the pump housing lower end pump cover that is tightly connected, in pump housing inner chamber, adorn bent axle from top to bottom in regular turn by driven by motor, the piston that on bent axle, connects with connecting rod, be connected can be in the pump housing reciprocating plunger with piston rod, plunger is cylindrical, the tube end is solid, nozzle is towards pump cover, pump housing top sets out the water valve mouth, and the bottom is provided with into water valve port; When plunger water pump insert be in the low-lying drain after, the motion of motor drives bent axle, pass through connecting rod, piston makes plunger reciprocating in the pump housing, when plunger when the pump head opposite direction moves, the hole in water promptly from the water inlet valve port enter be full of in the pump housing after, the water inlet valve port is closed, when plunger moves towards the pump cover direction, water pressurized in the pump housing forces water to flow out from the water outlet valve port, by the connecting rod on the bent axle, piston drives the iterative motion of plunger at pump housing intercycle, when underground water being continued to flow hoist draining through voltage stabilizer, because plunger is the solid end, when moving in the pump housing, will produce very big resistance and consume the power of motor, this only have its flow of water pump of a piston cylinder very little; This external enwergy causes water outlet to be obstructed, and causes flow backwards piston place, and operation is inconvenient and owing to bent axle, connecting rod, piston are installed in the pump housing of one, also bring difficulty to installation, maintenance.

Summary of the invention

The purpose of this utility model is to avoid the shortcoming and defect part that exists in the above-mentioned prior art and provides and both reduce resistance, improves power and energy-conservation and lift is high, drain discharge greatly can installation, maintenance, four a kind of novel cylinder energy-saving water pumps easy to use.

The purpose of this utility model realizes with following technological scheme: four novel cylinder energy-saving water pumps, comprise the pump housing, pump cover, connecting rod, piston, plunger, advance, water outlet, it is characterized in that: by the piston case lid, the piston casing, suction chamber, the plunger casing, the pump housing of sealing assembling in regular turn, pump cover is tightly connected on the plunger casing of the pump housing, one side of suction chamber, the both sides of pump cover have respectively into, effluent pipe mouth, in the piston casing of the pump housing, adorn the piston of four band piston rods, corresponding with four pistons, the bent axle of four connecting levers is housed in the piston casing, piston body is flexibly connected with the corresponding connecting lever on connecting rod and the bent axle respectively, piston rod on the piston passes the black box in the pump housing respectively, suction chamber, enter in the plunger casing, be on the piston rod segment in the plunger case and be set with plunger, four plungers are respectively cylindrical shape, and separately can be at corresponding connecting sleeve, reciprocating in the black box, the tube end of plunger, is respectively towards pump cover, be covered with open-work on each bottom surface respectively, corresponding with open-work position at the bottom of the tube, put into the water valve on the tailpiece of the piston rod outside at the bottom of the tube respectively, the water inlet valve communicates with water inlet pipe mouth respectively, consistent with the plunger vertical center line, corresponding with the inner diameter location of plunger case, take on the water valve in pump cover respectively, the water outlet valve is connected with effluent pipe mouth respectively.Described black box in the pump housing amounts to four, each black box is made up of two seal rings and a spacer ring, in the pump housing, adorn two seal rings, the spacer ring that has osculum in two interannulars dress, its osculum is connected with weep hole on the pump housing, this black box can improve the sealing in the piston case, after first seal wears, the weep hole that the water that infiltrates can flow on the pump housing from the osculum of spacer ring is discharged: described four open-works that the cylindrical plunger bottom surface is covered with, do not influencing under the integrally-built prerequisite of tubular, it is maximum that the area of open-work makes every effort to reach, its open-work or make circular hole or do raceway groove in the arc-shaped hole, corresponding with these open-works, dress is by valve block on the tailpiece of the piston rod outside at the bottom of the tube, and gland leads, Returnning spring, the water inlet valve that tightening nut is formed, and water inlet valve, open-work is connected with the intake pipe of suction chamber; Corresponding with the inner diameter location of plunger body, in pump cover, adorn by gland, the water outlet valve that the sealing gasket that valve seat cover, valve seat put, valve disc, Returnning spring, limited post are formed, the water outlet valve is connected with the effluent pipe mouth of pump cover both sides respectively.Starting electrical machinery drives bent axle, bent axle is by four connecting rods, drive four pistons, thereby it is reciprocating in the plunger casing to drive four plungers, when plunger moves to the pump cover opposite direction in the plunger case, form vacuum in the plunger case, the water outlet valve that is in the pump cover is closed, the water inlet valve at place, plunger bottom surface is influenced by negative pressure of vacuum and opens, come the outer draining of self-pumping to pass through intake pipe, intake chamber and entering in the plunger case, when plunger when the pump cover direction is moved, the water inlet valve is closed under the resistance of the effect of Returnning spring and water naturally, and the water outlet valve is opened under hydraulic pressure and air pressure, make the interior water of plunger case by the water outlet valve, effluent pipe mouth is made periodic iterative motion through voltage stabilizer and discharging by four plungers in the plunger case, make the utlity model has high-lift, the drainage performance of big flow, thus realize of the present utility model efficient, energy-conservation, the purpose of big flow draining.

Compared with prior art, because the utility model adopts four piston cylinders, the entery and delivery port position arrangement is reasonable, makes advancing, drain to smoothness of water, reduce resistance, can not only increase discharge capacity, and significantly improve effect, realize energy-conservation and installation, maintenance, easy to use
