Abstract
The invention discloses a ceramic plunger high-pressure water pump. The ceramic plunger high-pressure water pump comprises a pump body and a pump head; a crank shaft is mounted in the pump body; a connecting rod is mounted on the crank shaft; the other end of the connecting rod is connected with the tail of a crosshead by use of a cross pin head; the head of the crosshead is fixed with the plunger by use of a fastening bolt; the plunger is sealed in the pump head by use of a sealing ring; the plunger is an all-ceramic material sintered plunger; a water outlet valve seat and a water inlet valve seat are mounted on one side of the pump head; a water outlet valve core is mounted on the water valve seat; a return spring sleeves the water valve core; a water inlet valve core is mounted on the water inlet valve seat; a return spring sleeves the water inlet valve core. The high-pressure water pump is simple in structure and steady in running; the friction coefficient of the movable part is small, the abrasion is reduced, the airtightness is enhanced and the service life of the water pump is prolonged.
Description
Technical field:
The present invention relates to a kind of high-pressure water pump, more specifically relate to a kind of positive displacement high-pressure water pump.
Background technique:
Plunger high-pressure water pump needs the indispensable power plant of high voltage power source device.At present, domestic high pressure plunger water pump mainly contains steel column plug, has steel plunger surface to carry out thermal spraying ceramic, surfacing pottery, electro-plated pottery layer, but these plungers are large to antithesis Sealing friction factor, sealing part abrasion can be caused short for fast working life, thus there is water leakage phenomenon, and it is large to run vibrating noise, volumetric efficiency is low, therefore cannot meet the equipment needs of some high requirement.
Summary of the invention:
For above-mentioned deficiency, the object of the invention is to provide that a kind of friction factor is little, good endurance, the ceramic plunger high-pressure water pump that operates steadily
The present invention is achieved by the following technical solutions.
A kind of ceramic plunger high-pressure water pump, comprise the pump housing and pump head, in the described pump housing, bent axle is installed, bent axle is provided with connecting rod, the corresponding the other end of connecting rod is connected with crosshead by cross pin head, head and the plunger of described crosshead are fixed by clamping bolt, and plunger seals with seal ring in pump head; The pump housing supports bent axle and is rotated, thus drivening rod, plunger do straight reciprocating motion.
Described plunger is full stupalith sintering plunger, between full stupalith sintering plunger and Sealing friction factor very little, in addition, ceramic plunger is after polishing and have self-lubricating function, minimum and can carry out long-life use to the wearing and tearing of Sealing.
Described pump head side is provided with water outlet valve seat, water outlet valve seat is provided with water outlet spool, and water outlet valve core upper sleeve has return spring, composition water outlet assembly; Described pump head opposite side is provided with inlet valve seat, described inlet valve seat is provided with into water spool, described water inlet valve core upper sleeve has return spring, composition water inlet assembly.Water outlet valve seat, water outlet spool, inlet valve seat and water inlet spool are full stupalith sintering and form, and fretting wear is little, can extend its working life.
Beneficial effect: high-pressure water pump structure of the present invention is simple, operates steadily, runs vibrating noise little; Plunger of the present invention uses material to be full stupalith sintering, stupalith has that splendid abrasion resistance properties, friction factor are little, perfect heat-dissipating, acid resistant alkali, high temperature resistant feature, overcoming traditional plunger causes greatly sealing part abrasion fast working life short and the defect of easily leaking to antithesis Sealing friction factor, decrease the wearing and tearing to Sealing, enhance sealing, extend its working life; In addition, water outlet valve seat, water outlet spool, inlet valve seat and water inlet spool are full stupalith sintering and form, farthest reduce the friction and wear that valve seat and spool are constantly being opened closing course and produced, greatly increase the life-span of water inlet and outlet valve seat and spool, also avoid to a certain extent leaking.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present embodiment.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the invention will be further described, but the protection domain of invention not limit by embodiment.
See Fig. 1, a kind of ceramic plunger high-pressure water pump, comprise the metal pump housing 1 and copper pump head 9, metal cabinet 1 and copper pump head 9 are bolted together; The bottom of the pump housing is provided with bent axle 2, connecting rod 3 bent axle 2 is equipped with, the corresponding the other end of connecting rod 3 is linked together by the afterbody of cross pin head 4 with crosshead 5, the head of crosshead 5 is fixed together by plunger clamping bolt 8 and ceramic plunger 6, form double-action mechanism, namely the pump housing 1 supports bent axle 2 and is rotated, thus drivening rod 3, ceramic plunger 6 do straight reciprocating motion; The material that ceramic plunger 6 uses is the full stupalith sintering after polishing; Ceramic plunger 6 part is positioned at the pump housing 1, and another part is positioned at copper pump head 9, and wherein, the part Sealing 7 in copper pump head 9 seals with copper pump head 9.
Copper pump head 9 side is provided with water outlet valve seat 10, water outlet valve seat 10 is provided with water outlet spool 11, and on water outlet spool 11, cover has return spring 12, composition water outlet assembly; Copper pump head 9 opposite side is provided with inlet valve seat 13, described inlet valve seat 13 is provided with into water spool 14, and on described water inlet spool 14, cover has return spring 15, composition water inlet assembly.Water outlet valve seat 10, water outlet spool 11, inlet valve seat 13 and water inlet spool 14 are full stupalith sintering and form, farthest reduce the friction and wear that valve seat and spool are constantly being opened closing course and produced, greatly increase the life-span of water inlet and outlet valve seat and spool, also avoid to a certain extent leaking.
