Description
Technical field
The invention belongs to pumping unit, relate to a kind of hydraulic ram that energy-saving and noise-reducing improves structure that possesses.
Background technique
Hydraulic ram be a kind of be power with flowing water, by mechanism, produce water hammer effect with low water head can be converted to high head can senior picotan.It does not need the traction with any prime mover (motor, internal-combustion engine or steamer), so do not consume electric power and fuel, does not use lubricant oil yet.It simple in structure, easily manufactured, Operation and Maintenance is easy, and is sturdy and durable.It is the good water lift that the drought-relief and protection of the harvest farmland is built in mountain area, rolling country with getting twice the result with half the effort, also is the good water lift that area solution pastoral farming, forestry, industry and the domestic water of waterpower resourses are arranged.Yet current hydraulic ram but exists defectives such as water displacement is big, noise is big, efficient is low, high-lift job insecurity, thereby has limited promoting the use of of hydraulic ram.
The spool of dash valve mostly is the disc or the structural type of clapper, high-velocity flow produces huge pressure when dash valve, produce bigger water impact resistance, thereby cause the water flow dynamic energy loss bigger, big water gaging directly flows out from dash valve, the water yield that is raised seldom, traditional hydraulic ram maximum amount of water utilization ratio only 20%.Hydraulic ram in the course of the work, dash valve under the effect of water hammer effect, spool part vertical tremor, the noise that valve bump produces can reach more than 100 decibels, has very that the person can reach 130 decibels, this is a kind of more serious noise pollution in the mountain area.
Inlet valve also exists same problem, the switch performance of tradition water hammer pump water inlet valve is relatively poor, the design of inlet valve is too complicated, mechanism by spool or deadweight realize the effect of the unidirectional conducting of inlet valve often, there is bigger time-delay in the switch of valve, thereby cause big water gaging from the air chamber pump housing that refluxes, reduced the water lift efficient of hydraulic ram.Someone considers that the hollow core valve with spherical valve and interior inflation body improves the performance of inlet valve, and still, they are difficult to satisfy high-frequency work requirements.
What tradition water hammer air bottle of pump was used is common iron flask or cylinder of steel, water contacts with the inwall of air chamber, more easily produce dissolved oxygen corrosion and electrochemical corrosion, in addition, because pressure change is rapid in the air chamber, brings the small bubble that come into the motion of dash valve and can on inwall, produce cavitation erosion, these destructions are accumulated over a long period and can be made the air chamber excessive fatigue and damage, the detonation phenomenon easily takes place, thereby the work of traditional hydraulic ram is unsettled and is insecure.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes deficiency of the prior art, and a kind of hydraulic ram that energy-saving and noise-reducing improves structure that possesses is provided.
Be the technical solution problem, the scheme that the present invention takes is:
A kind of hydraulic ram that energy-saving and noise-reducing improves structure that possesses is provided, comprises the dash valve and the inlet valve that are connected in the pump housing, inlet valve and air chamber join; Described dash valve comprises vertical valve body, and its middle part is the drum shape, and its upper and lower end is respectively the tubular junction that joins with flange; Wherein descend the size of end flange and the pump housing flange of hydraulic ram to be complementary, the central hole size of upper flanges and the diameter of valve rod adapt; The spool of dash valve has upper half part of frustoconic shape and lower half portion of spindle shape, rounding off between two-part up and down; The center and the valve rod on spool top join, and valve rod is upward through upper flanges; Valve rod is provided with a fixing limiting stopper, establishes resilient pad between limiting stopper and the upper flanges.
As improvement, the surface of described spool has one deck foamed aluminium hole vibrationproof coating.
As improvement, described resilient pad is a rubber pad, is fixed in the surface of upper flanges.
As improvement, also comprise several balancing weights, through hole is established in its central position, and its internal diameter size and valve rod are complementary; Through hole inside and valve rod upper end face are provided with the screw thread of mutual coupling.
As improvement, the described pump housing is a three-port structure, and the one side is a water inlet, and opposite side connects dash valve, and the vertical connection inlet valve in the middle part of valve body assembles air chamber above the inlet valve, and inlet valve also joins with water outlet.
As improvement, described inlet valve is the diaphragm type safety check, and its spool is a porous slab, and each plate hole is embedded with the single-pass barrier film.
As improvement, described single-pass barrier film is the rubber-like film body, has cross fancy opening, supports with four-bladed vane under the single-pass barrier film.
As improvement, described air chamber has double layer construction: outer is the rigidity outer wall, and its inside is the air chamber inner bag that a diaphragm of rubber constitutes.
As improvement, the air chamber inner bag that described air chamber inner bag is a filling nitrogen.
As improvement, the top of described air chamber rigidity outer wall is provided with the inflation inlet that joins with the air chamber inner bag, and the lower end of air chamber rigidity outer wall is a water outlet, is connected to inlet valve with flanged surface.
Beneficial effect of the present invention is:
1, spool is the combination of frustoconic shape and spindle, and its cross section is streamline, has effectively reduced the resistance that water streams, thereby reduces the loss of flow energy, for follow-up generation water hammer effect provides bigger energy source; The efficient of tradition about 70% can be brought up to more than 80%.
2, spool face is provided with foamed aluminium hole vibrationproof coating.The foamed aluminium light weight, sound-absorbing, sound insulation, damping property are good, damping, energy absorption performance excellence, good weatherability, corrosion-resistant, anti-aging, do not fire, heat insulation, resistance to heat is good, nontoxic, harmless, recyclable utilization and be easy to installation and processing, be the ideal green environment-friendly materials, every field has a wide range of applications.The impact noise that this coating produces in the time of can effectively reducing spool and valve body bump can be controlled at noise below 80 decibels through assessment; And traditional hydraulic ram noise is big, up to 105～130 decibels.
3, improved the structure of valve rod, section surface is established screw thread on valve rod, can adopt the form that screws balancing weight to change the counterweight of spool, this method is convenient and simple and sturdy and durable, overcome tradition with spring change the counterweight mode easily get rusty, fragile, change defective such as part trouble.
4, the structure of improvement air chamber diaphragm of rubber is introduced air chamber, and to change normally used air is the blanketing gas of the good nitrogen of compressibility as air chamber, has improved the efficient of complete machine and the utilization ratio of flow energy, simultaneously, has avoided dissolved oxygen corrosion.Also avoided causing the risk of shutdown or detonation owing to the molten water loss of long-term work pressurized air.
5, improved the structure of one-way valve, selected single-pass barrier film with elastic film bulk main function components for use as the one-way valve spool.Can reduce the valve body stress damage, and improve the switch performance of valve body, reduce the backflow of water.The design of inlet valve is broken the normal procedure, and the membrane technology of uses advanced is in spool, and it has in light weight, advantages such as inertia is little, manufacturing is simple, cost is low, nothing is leaked, easy replacing, can adapt to high-frequency job requirement, improves lift and working efficiency.
