Technical field
The invention belongs to water pump applied technical field, and in particular to a kind of jet pump.
Background technology
Jet pump is a kind of fluid driven pump, and fluid driven pump does not have machine driving and machine work component, and it is by another
A kind of energy of working fluid does power source to convey low energy quantity of fluid, has good peace during for aspirating inflammable and explosive material
Quan Xing.Liquid-jet vacuum pump is to extract the gas in container using the high-speed jet by nozzle to obtain the equipment of vacuum,
Also known as jet vacuum pump, in Chemical Manufacture, often for the purpose of producing vacuum.
Industrial jet pump, also known as jet pump and injector.Using the jet-action of pressurized working fluid come transport Stream
The pump of body.It is made up of nozzle, mixing chamber and enlarged tube etc..For the sake of making smooth operation, a vacuum chamber is set at trunnion（Also referred to as
Suck room）；In order that two kinds of fluids can be sufficiently mixed, there is a mixing chamber behind vacuum chamber, during operation, working fluid is with very
High speed is sprayed by nozzle, and low pressure is formed in vacuum chamber, makes to be conveyed liquid suction vacuum chamber, subsequently into mixing chamber.
The working fluid of high-energy and low energy are sufficiently mixed by conveying liquid in mixing chamber, are exchanged with each other energy, speed also by
It is gradually consistent, enter diffuser casing from trunnion, speed slows down, and static pressure is gone up, and reaches the purpose of conveying liquid.The workflow of jet pump
Body can be gas（Air or steam）And liquid, steam ejector pump, air ejector and water stream injection pump are common are, is also had
It is a kind of to do the jet pump of medium, i.e. oil diffusion pump and oily booster pump with oil, it is for obtaining the main of high vacuum or ultrahigh vacuum
Equipment.
Currently, the jet pump of traditional structure, its service life is short, operating efficiency is low and lift end, easily heating etc., can not
Meet the high standard assembling use demand of existing manufacturing enterprise.
Therefore, a kind of jet pump is provided based on above mentioned problem, the present invention.
The content of the invention
Goal of the invention：It is an object of the invention to provide a kind of jet pump, its design structure rationally and with service life it is long,
The characteristics of conveniently moving, while solve the problems such as existing injection pump lift is short, radiating is big, it is easy to just install and safeguard, is applicable
Scope is wide.
Technical scheme：The present invention provides a kind of jet pump, including casing, and pump head, the fan blade being used in combination with casing
Cover, and the first dust cap, water filling screw, the second dust cap, the first sealing, conducting element, the leaf being used in combination with casing, pump head
Wheel, the second sealing, mechanical seal, bracket, thrower, protecgulum, clutch shaft bearing, the first screw, rotor, second bearing, pad and
Stator, and bonnet, the second screw, fan blade, the jump ring that casing, blade cover are used in combination, and it is arranged on casing side and matching
Close the 3rd sealing used, capacitor box back box, the 3rd screw, electric capacity, the 4th sealing, capacitor box lid, the 4th screw, the 5th spiral shell
Silk, sheath and briquetting.
The technical program, the jet pump, in addition to for being arranged on pump head and being used in combination with rotor, stator
Six screws, power line and plug, pressure gauge, pressure switch and electric wire.
Compared with prior art, a kind of beneficial effect of jet pump of the invention is：Its design structure is reasonable and has
The characteristics of service life is long, conveniently moving, while solve the problems such as existing injection lift is short, radiating is big, be easy to just install and
Safeguard, it is applied widely.
