Description
Affiliated technical field
The present invention relates to a kind of high-effect three cylinder fine ceramics plunger pumps
Background technique
Plunger pump is an important device of hydraulic system.Its relies on plunger to-and-fro motion in cylinder body, the volume of seal operation cavity volume is changed realize oil suction, presses oil.Plunger pump has advantages such as rated pressure height, compact structure, efficient height and Flow-rate adjustment convenience, is widely used in the occasion that high pressure, big flow and flow need be regulated, in hydraulic press, engineering machinery and boats and ships.
Plunger pump is divided into axial piston pump and two kinds of representational structural types of radial plunger pump; Because radial plunger pump belongs to a kind of novel technology content than higher high effective pump, along with the continuous quickening of production domesticization, radial plunger pump will inevitably become the important component part of plunger pump application.
Plunger pump is a kind of of reciprocating pump, belongs to volume pump, and its plunger leans on the eccentric rotary of pump shaft to drive, to-and-fro motion, and it sucks and expulsion valve all is an one-way valve.When drawing outside the plunger, working room's internal pressure reduces, and outlet valve cuts out, and when being lower than inlet pressure, inlet valve is opened, and liquid gets into; When pushing away in the plunger, working room's pressure raises, and inlet valve cuts out, and when being higher than outlet pressure, outlet valve is opened, and liquid is discharged.
In use; Normal the following topic that is occurs: the oil hydraulic pump output flow is not enough or do not export that fluid, corrosion resistance are poor, output flow fluctuation, delivery pressure are unusual, vibration and noise, leakage of oil, life-span are short, the short insoluble problem of plunger pump that then becomes of particularly leakage of oil, corrosion resistance difference and life-span.
Summary of the invention
To above-mentioned deficiency, the invention provides a kind of high-effect three cylinder fine ceramics plunger pumps, this pump is a high speed fine ceramics plunger pump; Plunger adopts fine ceramics material, makes precision, and hardness is high; Good corrosion resistance, any surface finish gets Sealing and improves working life; This pump structure is compact, and volume is little, and is in light weight, reliable operation.
The present invention solves the technological scheme that its technical problem takes: this pump by inlet valve silently, water inlet cushion block, inlet valve assembling, pump head, outlet valve assembling, outlet valve silently, water seal, secondary water seal, crankcase, bent axle, bonnet, oil ga(u)ge, oil-draining locknut, ceramic plunger link assembly, oil sealing form; It is characterized in that mechanical energy is converted into water flow pressure can; Power passes through connecting rod; Rotatablely moving of bent axle changed into the to-and-fro motion of plunger; When plunger is retreated; Because of pull of vacuum; Inlet valve is opened and outlet valve is closed, and water is inhaled in the cylinder; During plunger advancement, because of hydraulic pressure in the pump raises, inlet valve is closed, outlet valve is opened, and high pressure water is discharged through high-voltage tube from outlet valve.To rotatablely move through high-pressure service pump and to be converted into the straight reciprocating motion of plunger; And the one-way cock through one group of positive and negative placement; The water that reaches nature is forced into high pressure water; Through external pressure regulator valve control system backwater amount; Thereby reach the effect of adjustable in pressure joint, reach the switch water jet, drive and press energy-conservation and the effect in working life of prolongation facility through spray gun.When closing spray gun, through closing check valve, drive to drive and press the valve motion in the normal running, back down valve ball, the system that reaches drives and presses motion, thereby reaches energy-conserving action; When opening spray gun, the pipe internal pressure reduces, and check valve is opened under the pressure difference effect; Make to drive and press the valve reversing motion, valve ball and valve seat driving fit, control backwater amount; Thereby reach system's normal operating pressure state, finally realize a kind of high-effect three cylinder fine ceramics plunger pumps.
It is characterized in that said water seal, secondary water seal adopt two sealing structure for water to guarantee that pump seals lastingly, unique major-minor water seal combination guarantees that pump is watertight, and the water lubrication technology is adopted in the major-minor water seal, prolongs the working life of water seal;
Said ceramic plunger adopts advanced full spray pottery technology, and surface roughness reaches 0.2, prolongs the working life of oil sealing water seal.Advanced processing technology guarantees element precision, solves the too high problem of pump oil temperature;
Said ceramic plunger connecting rod, correct grinding and OPO are handled bent axle and the low AL-SI-CU alloy connecting rod of moulding of high tenacity, guarantee the lasting reliably working of pump;
The invention has the beneficial effects as follows: this pump is a high speed fine ceramics plunger pump, and plunger adopts fine ceramics material, makes precision, and hardness is high, good corrosion resistance, and any surface finish gets Sealing and improves working life; This pump structure is compact, and volume is little, and is in light weight, reliable operation.
Description of drawings
In claims of present patent application, point out theme of the present invention particularly, and clearly it has been proposed patent protection.Yet with reference to following detailed description and accompanying drawing, can better understand of the present invention about structure and implementation method with and purpose, characteristic and advantage.
