The structure of effect.14 bottom of fuel tank is equipped with silk noil stifled 20.
Designing technique principle：
1. thermosyphon effect：So that liquid portion is vaporized using heating, forms liquid-vapor mixture, the fluid density being vaporized becomes smaller,
The process of liquid circulation, exchange is completed as motive force using density contrast.In the present invention, make pump using thermosyphon effect
Deep fat in the oil groove of lid machine sealing chamber room tail portion rises to fuel tank top, the cold oil of fuel tank lower part sinks, supplement oil groove oil mass.
2. gravity principle：When pump machine starts, transmission shaft high-speed rotation, the oil in oil groove can be stirred by the axis of high-speed rotation
It is dynamic, and centrifugal rotary motion is presented, when the deep fat in oil groove is pushed to tedge because of a rotary motion part, lower immersed tube
Cold oil due to gravity, can be automatically replenished, to realize deep fat rise, cold oil sink enclosed in recycle.Oil exists
Constantly cooling, cooling during rising and sink by oil pipe connector.
3. the dry rotation protection device of anhydrous mechanical seal makes full use of thermosyphon effect and gravity principle, pass through closed circuit system
Medium in system（Cold oil）, petroleum pipeline（Or finned tube）, metallic oil tank, the amount of heat that mechanical seal is generated by dry friction
Sufficient heat exchange is carried out, the friction pair of machine envelope is fully cooled, it is ensured that pump machine can anhydrous for a long time, lossless formula operating.
Mentality of designing：
1. utilizing thermosyphon effect and gravity principle, an oil groove is added behind pump machine machine sealing chamber room tail portion, machine envelope stationary ring
And by machine envelope and skeleton oil seal, the side vertical direction of oil groove bores holes up and down, a fuel tank, fuel tank position is filled above pump
Holes is bored in the homonymy vertical direction of oil groove drilling, oil pipe connector connects fuel tank and oil groove by " upper to above and below under " principle.
The heat that the secondary friction of machine envelope friction generates can pass to the lubricating oil in oil groove, and the lubrication oil density of heating reduces and in oil groove
Toward float, simultaneously because the oil in oil groove does centrifugal rotation movement, deep fat is pushed into tedge, cold oil due to gravity and
Sink, the deep fat of floating is raised to by oil pipe connector in the fuel tank on pump, and the deep fat floated in fuel tank can float on fuel tank
Top, the low-temperature oil being now placed in fuel tank can sink to and supplement oil mass in oil groove, and deep fat reaches fuel tank in floating by oil pipe
During renewed with recycling constantly radiating, drop back to low temperature and be gradually reduced oil-recovery tank.
2. fuel tank configures petroleum pipeline（Finned tube heat dissipation can be used）, oil level, oil thermometer, fuel tank cap, filter screen and silk of draining the oil
It is stifled, can timely monitor fuel tank oil level and oil temperature, refuel or change oil when necessary；
Operation principle：
A. the suspension 6, link 5, pump cover 4 and the pump housing 3 of pump machine are assemblied in pump cover 4 by being bolted fastening, machine envelope stationary ring 10
In stationary ring hole, these accessories are static.Impeller 2 is fastened on by impeller bolt 1 on axis 7, and machine envelope rotating ring 8 is wrapped in by rubber parts
On axis 7 and by the wheel hub end face of impeller 2 and machine envelope 10 axially position of stationary ring and pump chamber is sealed, machine seals rotating ring 8 with main shaft 7 and leaf
Take turns 2 rotary motions together.Machine envelope, which ensures that the medium of pump chamber will not leak, will not allow the lubricating oil in oil groove to enter pump chamber pollution
Medium；Machine seals the oil groove for being sealed jointly in pump cover end with outside framework oil seal 9 and forming sealing.
B. fuel tank 14 is fixed on 5 top of link by the pump housing-pump cover bolt 11, installs oil filler right over fuel tank 14, contains
Filter screen 15 and fuel tank cap 16, filter screen are to ensure the clean free from admixture of lubricating oil, and impurity enters the mill that lubricating oil can accelerate machine to seal
Damage；Oil level and the meter 8 of oil temperature can be monitored by bolt 18, the installation of gasket 19 in 14 side of fuel tank, pacified in the bottom of fuel tank 14
Silk noil stifled 20 is put, lubricating oil is conveniently replaceable；
C. it is located at the side of 4 finishing bathtray of offside and pump cover of meter 17 on fuel tank 14（With the holes homonymy bored on fuel tank）Vertical side
Make oil groove top company by the principle of " upper to above and below under " the upper and lower oil pipe connector 12 and 13 that is linked and packed to upper and lower holes of boring
Logical fuel tank top, oil groove lower part connection fuel tank lower part；
The anhydrous dry rotation protection device of mechanical seal can be directly installed on pump or other universal machines, pump or other universal machines
Before operating, fuel tank is contained into suitable lubricating oil, lubricating oil is transported to the oil groove after mechanical sealing static ring by oil pipe connector
Interior, oil groove is sealed by machine and skeleton oil seal.Machine envelope stationary ring is fully immersed in the lubricating oil in oil groove, and fully and lubricating oil
Contact.The oil groove of fuel tank and pump cover is respectively equipped with into and out of oil pipe line and uses oil pipe connector by " on to above and below under " principle
Connection.Utilize thermosyphon effect：Lubricating oil absorbs the heat that dynamic and static ring friction generates when mechanical seal operates, after absorbing heat
Lubrication oil density reduces toward floating, and by upper oil pipe connector until in fuel tank, the low-temperature oil in fuel tank is connected by lower oil pipe
Part sinks, supplements oil mass in oil groove, and heat is constantly discharged into sky by oil during floating and sinking through tube wall and oil tank wall
In gas, and gradually it is cooled to low-temperature oil.This cycle in cycles, realizes the consecutive low temperature operating of machine envelope.In the pump of dry type installation
It is upper to use this device, it can be done with auxiliary pump in the case where not pouring water completely and turn to realize self-priming；Either dry type installation pump, from
Sucking pump or immersible pump, it is anhydrous dry to turn mechanical seal guarantor in the case where failing to shut down in time when working media is drained completely
Protection unit can close the machine of pump machine prolonged protection, and pump machine can be made to be in the dry work shape turned anhydrous for a long time
State is lost caused by be effectively reduced due to machine envelope is burnt
Embodiment of the present invention is only the description carried out to the preferred embodiment of the present invention, not to present inventive concept
It is defined with range, under the premise of not departing from design philosophy of the present invention, engineers and technicians are to the present invention's in this field
