Description
Technical field
The present invention relates to a kind of plunger pump, be particularly related to a kind of plunger pump of oil-free lubrication.
Background technique
Plunger pump is compared centrifugal pump and is had reliable operation, flow is big, pressure is high characteristics, and its potable water that is widely used in tall building is carried.At this plunger pump structure, be example with the single plunger system of plunger pump, it comprises that a plunger cavity and can reciprocating type axially movable plunger; Be provided with water intake and water intake in the plunger cavity; And water intake is provided with into water one-way valve, and water outlet is provided with out water one-way valve, when plunger negative pressure occurs in the chamber when a direction is moved; At this moment the one-way valve opens of intaking and water outlet closed check valve; Liquid is inhaled in the chamber, and malleation occurs in the chamber during to the motion of another direction when plunger, water inlet closed check valve and go out water one-way valve and open; Plunger is discharged intracavity liquid compression back from the water one-way valve of opening that goes out, just formed continuous liquid supply after this working method continuous motion.
With regard to present structure, the plunger of plunger pump only in plunger cavity the position contact with carrying liquid, all the other positions of plunger then are positioned at valve body and conveying liquid completely cuts off; At this, because of the reciprocating frequency of plunger is very high, the friction of itself and valve body not only can cause the wearing and tearing of plunger; Also can produce great amount of heat simultaneously; In the middle of practical set,, generally the plunger in the valve body is partly added butter and be lubricated for reducing friction between the two.Though this structural design has reached the purpose of reducing friction; But also brought some other problem simultaneously; Butter like lubricated usefulness can penetrate into plunger cavity at work and pollute conveying liquid, and this can be to people's the healthy adverse influence of bringing particularly for the conveying of potable water; In addition, the replacing of the butter of lubricated usefulness after long-time the use added also cumbersome.In addition, be lubricated, but how many frictions still can exist even added butter; This also can accumulate great amount of heat after plunger works long hours, but in the middle of present structure, special sink is not set; Only through the spontaneous radiation heat radiation of valve body itself, radiating effect is very bad, and this can bring certain burden to plunger to a certain extent; Aggravation is worn and torn, and has had a strong impact on the working life of plunger.
Summary of the invention
To the problems referred to above, the invention provides a kind of plunger pump of oil-free lubrication, its plunger is directly through carrying liquid to be lubricated and lowering the temperature, and has the characteristics of easy to use, good heat dissipation effect, cleanliness without any pollution.
For realizing above-mentioned purpose, the present invention adopts following technological scheme:
A kind of plunger pump of oil-free lubrication comprises valve body and plunger, is provided with plunger cavity in the valve body, and plunger cavity is provided with water intake and water outlet, and water one-way valve is installed out on the water outlet, it is characterized in that: be provided with a water chamber and intake chamber in the said valve body; Wherein water chamber is provided with water inlet at the top, and water chamber is provided with intercommunicating pore and is communicated with intake chamber in the bottom, and water chamber is provided with plunger hole between madial wall and plunger cavity, and water chamber is provided with and the extraneous plunger mounting hole that is communicated with of valve body at outer side wall; Said intake chamber is positioned at said plunger cavity bottom, and it is communicated with plunger cavity through described water intake, is provided with into water one-way valve in the intake chamber simultaneously, the intercommunicating pore unilaterally connected of water inlet one-way valve and water chamber; Said plunger head is arranged in plunger cavity, and plunger middle part is passed plunger hole and is arranged in water chamber, and plunger tail is passed the plunger mounting hole and stretched out valve body and be connected with power system.
Above-mentioned plunger cavity is near being provided with the seal washer that plunger cavity and water chamber are separated fully between plunger hole position and the plunger.
Be provided with between above-mentioned plunger mounting hole and the plunger and make water chamber and the extraneous gasket seal that seals.
Above-mentioned water chamber bottom one side also is provided with a sewage draining exit, and sewage draining exit is provided with a blocking cap.
The present invention in use; Outer water is at first got into by the water inlet at water chamber top through water pipe, realizes that at current plunger that centering portion is arranged in water chamber lowers the temperature and lubricate in the process of water chamber bottom, subsequently when in the plunger cavity during generation negative pressure; Water inlet one-way valve opens and water outlet closed check valve; The water of water chamber is connected, and the hole sucks and get into intake chamber and plunger cavity, and when producing malleation in the plunger cavity, water inlet closed check valve and go out the water one-way valve unlatching; Water in plunger cavity is discharged by water outlet, and continuous motion has just formed the continuous liquid supply of plunger pump according to this.
In the present invention, the lubricated and cooling at plunger head and middle part is directly realized by the water of carrying, and has reached the purpose of oil-free lubrication, has the characteristics of cleanliness without any pollution.In addition, the water in the work in water chamber and the plunger cavity constantly flows, and can take away the heat of plunger rapidly, has played good cooling-down effect, can effectively avoid frictional heat in the plunger to-and-fro motion and accumulates the problem that heat raises its temperature.
In addition, for ease of the cleaning of dirt in the water chamber, the present invention is provided with the sewage draining exit that is in communication with the outside in water chamber bottom, and seals with blocking cap.The blocking cap of when cleaning, outwarding winding, by the water inlet water inlet, by the sewage draining exit water outlet, the dirt in the water chamber will be gone out very soon, clears up very convenient.
