Abstract
The utility model discloses a novel high-pressure cleaning pump head structure. A plunger is placed in a high-pressure steel sleeve, a guide copper sleeve, a supporting ring plunger sealing ring and a gasket are sequentially placed between the high-pressure steel sleeve and the plunger, a valve seat is mounted between the high-pressure steel sleeve and a large plug, a liquid inlet valve plate and a spool are disposed in a cavity of the valve seat, the liquid inlet valve plate is arranged at the front end of the plunger and connected with the high-pressure steel sleeve through a liquid inlet spring, a liquid cavity is formed between the liquid inlet valve plate and the spool, a liquid outlet cavity is formed between the large plug and the valve seat, and the liquid cavity is communicated with the liquid outlet cavity through the spool. The novel high-pressure cleaning pump head structure is a split pump head structure, replaces a traditional integral overall pump head, fundamentally resolves problems that the pump head is easy to be cracked because a seal at a connection position of an original structural pump head and the high-pressure steel sleeve is easy to be damaged, has the advantages of reasonable structural design, convenient maintenance, assembling and disassembling, reliable and safe usage and the like, and has extremely high use value in the field of high-pressure cleaning machines.
Description
Technical field:
The utility model patent relates to a kind of high-pressure wash pump parts, particularly relates to a kind of easy accessibility, reduces labor intensity, reduces the split type pump head of product operating cost.
Background technique:
The high-pressure wash pump is to utilize high pressure water jet that inner and outer surface rust, the dirt of cleaning object are cut, wash, and reaches the purpose that de-sludging is cleaned.Existing high-pressure wash pump all has motor, distribution box, water tank, the high-pressure wash pump head, several big systems such as fuel tank form, wherein motor passes through coupling, gear reduction, the rotation of drive three-throw crankshaft, act on connecting rod, slide-block mechanism makes slide block reciprocating in the casing skidway hole, and the drive plunger is done piston type to-and-fro motion generation pressure in high-pressure wash pump head hydraulic pressure cavity, and then water is outwards exported by high pressure, existing pump head is integral structure, long-play, pump head and high pressure steel bushing joint seal fragile and cause pump head to ftracture easily, labor intensity is big during the dismounting maintenance, need integral replacing when changing component, increase the enterprise operation cost.
The model utility content:
The utility model is at the deficiencies in the prior art, a kind of easy accessibility is provided, reduces labor intensity, reduce the split type pump head structure of product operating cost.
For realizing above purpose, the technical solution adopted in the utility model is as follows:
A kind of novel high-pressure washery pump pump head structure, it is characterized in that: described pump head assembly is split type pump head structure, can be provided with three groups of pump heads.
Described pump head assembly by preceding bearing shell, the back bearing shell, bent axle, link assembly, gland nut, O RunddichtringO, plunger, guiding copper sheathing, support ring plunger seal circle, packing ring, piston spring, high pressure steel bushing, feed liquor spring, feed liquor valve block, valve seat, seal ring, big plug, discharge opeing spring, spool, go out sap cavity, hydraulic pressure cavity is formed; Wherein link assembly connects as one by preceding bearing shell and back bearing shell and bent axle, and link assembly is connected with plunger, and plunger is positioned over high pressure steel bushing inside; Guiding copper sheathing, support ring plunger seal circle and packing ring are placed between high pressure steel bushing and the plunger successively, and plunger is played the role of positioning; Support ring plunger seal circle front end is provided with piston spring, and gland nut works the effect of being fixed to the guiding copper sheathing after installing, support ring plunger seal circle and packing ring; Be provided with the O RunddichtringO between gland nut and the plunger, lubricant oil seals in the motion of plunger process; Between high pressure steel bushing and the big plug valve seat is installed, the valve seat inside cavity is provided with feed liquor valve block and spool, and the feed liquor valve block places the plunger front end, and the feed liquor valve block is connected with the high pressure steel bushing by the feed liquor spring, and the feed liquor valve block has been opened reset response; Form hydraulic pressure cavity between feed liquor valve block and the spool; Cavity between big plug and the valve seat forms sap cavity; Hydraulic pressure cavity by spool with go out sap cavity and be communicated with; Spool is connected with big plug by the discharge opeing spring, and the unlatching of spool is played reset response.
The utility model patent pump head assembly is split type pump head structure, replaced the whole pump head of traditional integral type, it is fragile and cause the easy cracking phenomena of pump head fundamentally to have solved the sealing of original structure pump head and high pressure steel bushing joint, the single pump head of dismounting gets final product during maintenance, alleviate labor intensity, reduced the operating cost of product.
Description of drawings:
Fig. 1 is the utility model overall schematic;
Fig. 2 is Fig. 1 part A-A sectional view;
Embodiment:
As shown in Figure 1, a kind of novel high-pressure washery pump is made up of motor 1, coupling 2, crankcase 3, lubricating oil tank 4, pump head assembly 5, feed liquor interface 6, high-pressure outlet 7.
As shown in Figure 2, pump head assembly 5 by preceding bearing shell 51, back bearing shell 52, bent axle 53, link assembly 54, gland nut 55, O RunddichtringO 56, plunger 57, guiding copper sheathing 58, support ring plunger seal circle 59, packing ring 60, piston spring 61, high pressure steel bushing 62, feed liquor spring 63, feed liquor valve block 64, valve seat 65, seal ring 66, big plug 67, discharge opeing spring 68, spool 69, go out sap cavity 70, hydraulic pressure cavity 71 is formed.
During concrete enforcement, motor 1 drives the rotation of crankcase 3 middle gears by coupling 2, crankcase 3 is communicated with lubricating oil tank 4, for crankcase 3 provides mechanical motion required lubricant oil, in the crankcase 3 in bent axle 53 and the pump head assembly 5 link assembly 54 by front and back tile 51,52 connect as one, link assembly 54 is connected with plunger 57, motor 1 drives the rotation of bent axle 53 by coupling 2, be converted into and drive the piston type to-and-fro motion of plunger 57 in high pressure steel bushing 62, plunger 57 forms vacuum in left movement hydraulic pressure cavity 71, liquid backs down feed liquor valve block 64 from feed liquor interface 6 and enters hydraulic pressure cavity 71 inside at this moment; When plunger 57 moved right, feed liquor valve block 64 was closed, and liquid is pressurized, and spool 69 moves right, and liquid is thrown into out in the sap cavity 70 by high pressure, discharged through high-pressure outlet 7, and cleaning object is formed high-pressure wash.
The utlity model has reasonable in design, maintenance easy accessibility, use the advantages such as reliable safely, have very big use value at the high-pressure wash mechanical field.
