The nut 23 that bolt 24 is engaged；The bolt 24 through it is described enter water cover, the left chamber wall 2, the rotor chamber 3 and described
Right chamber wall 4, is arranged plain cushion 21 and elastic washer 22, then is fixed by the nut 23, to ensure nut 23 and bolt
The stability of 24 connections, reduces the stress concentration to right chamber wall 4, prevents from damaging the surface of right chamber wall 4.The quantity of the bolt arrangement
It is 6~10.
Alignment pin 25 is provided with the left chamber wall 2 with the right chamber wall 4, for aiding in installing.
It is provided with left chamber wall 2 with head piece, the current for configuring water inlet inflow.Water sucking mouth is provided with rotor chamber 3
With delivery port 11, it is described to be mutually adapted with the water sucking mouth with head piece.Delivery port 11 is arranged on the side of the rotor chamber 3, quantity
It is two, and symmetrically.Check valve 9 is installed at delivery port 11, check valve 9 includes valve and is connected with the valve
Spring 10, spring 10 be used for cause valve return so as to close delivery port 11 prevent discharge aqueous reflux, in valve and water outlet
Water outlet mouth sealing ring 26 is provided with 11 closures of mouth, for ensureing the sealing after valve closing.
It is provided with rotor in the rotor chamber 3, rotor dangles formula rotor for triangle, the dangle section of formula rotor of the triangle is curl
Triangle；Ring gear 8 is connected in rotor inner wall, ring gear and rotor coaxial；；Fixed gear 7 mutually intermeshes with ring gear 8, fixed
The diameter of gear 7 is less than the diameter of the inwall of ring gear 8 and more than the radius of the inwall of ring gear 8；Eccentric shaft 5 is arranged on by bearing part
In rotor, the one end of the eccentric shaft 5 connection put-put, the other end is connected with the fixed gear 7；Fixed gear 7
It is set on the eccentric shaft 5, fixed gear is fixedly connected with left chamber wall, fixed gear is coaxial with eccentric shaft.The eccentric shaft drives
Rotor eccentricity rotates, while ring gear produces inside engaged gear transmission with respect to fixed gear, whole rotor makees have rule in rotor chamber
The plane motion of rule, the volume Development pattern change between rotor and rotor chamber.
Further, the rotor has sealant with the contact portion of rotor chamber 3, specifically, the end face of rotor uses gap
Sealing；Rotor radial top is provided with diaphragm seal.Specifically, the premise that three-apexed rotor pumping function is realized is that pump housing volume is protected all the time
The enough sealings of card, the inside of three-apexed rotor pump is divided into three spaces of closing by three-apexed rotor, three during rotor motion
Individual closing space is being continually changing, and vacuum dehydration, compression draining is produced, in three tops of rotor and both sides end face needs and the pump housing
By contacting sealing between cavity wall, so the condition for considering to carry out contact seal is needed when rotor pump structure is designed, specifically
Including radial tip, reliably sealing and both sides end face are reliably sealed.Different, the sealing taken according to three-apexed rotor pump work pressure
Would also vary from, when pressure requirements are not high, can radially be sealed using diaphragm seal, end face can use clearance seal；Work as pressure
When power requirement is higher, in addition to radial direction is using diaphragm seal, end face need to encrypt strip of paper used for sealing；When such as requiring higher pressure, in order to seal more
It is reliability, in addition to using diaphragm seal, sealing strip, also offset need to be encrypted at apex seal two ends, to prevent liquid from sealing
Slot leakage between piece and link block.
Further, connected by sleeve 17 between the eccentric shaft 5 and left chamber wall 2, and by bearing 13 and screw
16 fix.It is connected with right chamber wall 4 and close by eccentric Simmer ring 12 by bearing part between the eccentric shaft 5 and left chamber wall 2
Envelope；The bearing part includes the bearing 13, bearing (ball) cover 15 and the screw 16 that cooperate.
Further, the eccentric shaft 5 is provided with bearing 18 and axle sleeve 14 with the rotor contact part, and is provided with sleeve
19。
The course of work of whole water pump is as follows：Power is input into by eccentric shaft, by fixed gear and the ring gear of rotor inner edge
Engagement, drives rotor to be rotated in the pump housing, and the rotating speed of axle is 3 times of rotor speed.Between rotor periphery cambered surface and pump housing type face
The volume cycle alternately changes, to realize the cyclic process of water suction, draining.Water is sucked from water inlet center, by the water suction of rotor
Mouth enters the water sucting cavity of pump；Rotor opens water sucking mouth in rotation with its arcuate perimeter, as swept volume is become larger water
In suction chamber.After water is full of whole chamber, and water sucking mouth is closed with its arcuate perimeter, is tapered into then as swept volume,
By water from outside discharge outlet excavationg pump.Rotor has three working faces, and each working face secondary drainage that absorbed water in a week is secondary, so
Rotor six drainings of water suction six times altogether weekly.Three-apexed rotor all the time with pump case keep combine closely, formed to export pressure and
The negative pressure of vacuum of water inlet.
In the present embodiment, eccentric shaft provides the power of eccentric motion for rotor as the input shaft of power, and as rotor is public
Turn to provide power.The eccentric distance e of eccentric shaft is designed as 7mm, and eccentric shaft is rotary shaft, and three-apexed rotor is deposited with eccentric shaft part
Needed between relative motion, therefore eccentric shaft and the pump housing and between three-apexed rotor and eccentric shaft part consider supporting with
Meet relative motion requirement, design to use and install deep groove ball bearing at eccentric shaft two ends and carry out the positioning of bearing, turns in triangle
Needle bearing is installed between son and eccentric shaft part and is positioned, grease lubrication is imposed to bearing.Rotor is doing eccentric motion
While, the ring gear connected firmly with rotor can be engaged with fixed external gear, promote rotor to carry out rotation, rotor
Rotation constitutes the special exercise of three-apexed rotor with revolution, and motion process of the three-apexed rotor in rotor chamber completes water suction, row
The process of water, similar to the acting process of rotary engine.According to rotor chamber contour line create into principle be a dynamic circle diametrically
For that secondly basic circle circumference again is without slippingly rolling, can learn that ring gear is 3 with the gear ratio of fixed gear:2, in Preliminary design
The number of teeth of gear ring is 42, and modulus is 1, and the number of teeth of external gear is 28, and modulus is 1.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
