Abstract
The utility model provides a kind of high-pressure hydraulic pump pump head, belongs to fluid machinery technical field.It solves existing high-pressure hydraulic pump because the hydraulic pressure born is larger, therefore easily causing screw stripped thread phenomenon loosens pump head, the problem of have impact on its pressurized effect.This high-pressure hydraulic pump pump head, drive end bearing bracket, reservoir chamber and rear end cap including the setting that cooperates successively, water inlet is axially offered on drive end bearing bracket, delivery port is radially offered on rear end cap, the outer ring of drive end bearing bracket and rear end cap is uniformly provided with some integrative-structures and symmetrical coupling block respectively, the center of coupling block offers cylindrical empty cavity configuration, coupling block internal clearance is fitted through provided with screw rod, and the both ends of screw rod have screw thread and coupled drive end bearing bracket, reservoir chamber and rear end cap by nut integral.The utility model makes it have the advantages of operation is more stable by being improved to pump head attachment structure.
Description
Technical field
The utility model belongs to fluid machinery technical field, is related to a kind of water pump, more particularly to a kind of high-pressure hydraulic pump pump head.
Background technology
Water pump is a kind of fluid machinery for being used to convey liquid or be pressurized liquid, mainly by the mechanical energy of prime mover or
Other external energies transmit liquid, increase liquid energy, high-pressure hydraulic pump because there is pressure height delivery port is pressurized for it,
Be usually used in spraying, be pressurized, draw water etc..Because high-pressure hydraulic pump has increasing action, therefore the hydraulic pressure born inside its pump head
More common water pump is much higher, and the assembling of traditional pump head be typically all by screw means connection, due to cost limitation not
Pump head can be made to very big, therefore the diameter of the finite volume of pump head its connecting screw is smaller, and high-pressure hydraulic pump is due to bearing
Hydraulic pressure is larger, therefore easily causing screw stripped thread phenomenon loosens pump head, have impact on its pressurized effect.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided one kind is firm in structure to make it
The more stable high-pressure hydraulic pump pump head of operation.
The purpose of this utility model can be realized by following technical proposal：A kind of high-pressure hydraulic pump pump head, including phase successively
Drive end bearing bracket, reservoir chamber and the rear end cap being mutually equipped with, water inlet, described rear end cap are axially offered on described drive end bearing bracket
Upper radial direction offers delivery port, it is characterised in that the outer ring of the drive end bearing bracket and rear end cap is uniformly provided with some one respectively
Body structure and symmetrical coupling block, the center of the coupling block offer cylindrical empty cavity configuration, in described coupling block
Gap is fitted through provided with screw rod, and the both ends of the screw rod have screw thread and by nut by drive end bearing bracket, reservoir chamber and rear end
Lid connection is integral.
The technique effect of this high-pressure hydraulic pump pump head is：Directly screw is opened up on end cap relative to traditional pump head again to pass through
Fastened by screw, the utility model fasten by setting coupling block on front and rear cover respectively, then with screw rod and nut, thus not by
Pump head volumetric constraint, can be according to actual conditions using the bigger screw rod of diameter, and screw thread is not easy stripped thread installation effect and more fastened,
Equivalent to the stability for adding water pump operation.
In a kind of above-mentioned high-pressure hydraulic pump pump head, the bottom of the drive end bearing bracket and rear end cap is respectively welded connect base
And mounting hole is offered in connect base.The easier for installation of pump head can be made by connect base.
In a kind of above-mentioned high-pressure hydraulic pump pump head, described water inlet is provided with block.The setting of block can have
Effect prevents large-sized solid impurity from entering pump head internal damage impeller with liquid.
Compared with prior art, this high-pressure hydraulic pump pump head by the improvement to its attachment structure make it have operation it is more steady
The advantages of determining.

Tightly drive end bearing bracket 1, reservoir chamber 2 and rear end cap 3 are coupled integral.
Further describe in detail, in order that pump head is easier for installation, the bottom of drive end bearing bracket 1 and rear end cap 3 is respectively welded
Mounting hole 10 is offered in connect base 9 and connect base 9.
In order to prevent large-sized solid impurity from entering pump head internal damage impeller with liquid, gear is provided with water inlet 4
Block 11.
Wherein, the quantity of coupling block 6 is per 4, side.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although more used herein drive end bearing bracket 1, reservoir chamber 2, rear end cap 3, water inlet 4, delivery port 5, coupling block 6,
