Abstract
An adjustable water ejector vacuum pump comprises a pump casing and is characterized by further comprising a nozzle casing, a cam gear, a nozzle sliding block and a subsidiary nozzle. The basic principle of the adjustable water ejector vacuum pump is that the nozzle sliding block is driven by the cam gear to move to enable nozzle size formed on the nozzle casing and the cam gear to change to achieve the purpose of adjusting the nozzle size. The adjustable water ejector vacuum pump is applied in an intelligent water ejector vacuum condensation system to adjust flow velocity and flow quantity of the nozzle in the water ejector vacuum pump timely and automatically, produced vacuum degree can avoid waste of energy while meeting production requirements, the weakness that a traditional water ejector vacuum pump is unadjustable in vacuum degree is overcome, and purposes of energy conservation and consumption reduction are achieved.
Description
Technical field
The present invention relates to the water injection vacuum pump that a kind of high velocity jet effect by water obtains vacuum, relate in particular to the water injection vacuum pump of a kind of adjustable spray flow and flow velocity.
Background technique
The working principle of water injection vacuum pump is: the water being provided by circulating water pump is by nozzle ejection at a high speed in jet pump, and injection water forms absorption negative pressure and produces vacuum.Water injection vacuum pump is widely used in the industrial fields such as metallurgy, chemical industry, light industry, medicine, food.The water flow that traditional water injection vacuum pump sprays and flow velocity are constant, and it produces fixing degree of vacuum.Degree of vacuum required in actual industrial production changes often, for meeting the operating mode of complex conditions, design need to configure water injection vacuum pump by maximum vacuum and certain margin of safety, in normal production, the degree of vacuum of redundancy need to discharge by the atmospheric valve being arranged on equipment or pipeline, causes the waste of energy.
Summary of the invention
The object of the present invention is to provide a kind of adjusting water ejector vacuum pump, be applied in intelligent water and spray flow velocity and the flow that in vacuum condensation system, can automatically adjust nozzle in water injection vacuum pump in good time, the degree of vacuum that makes it to produce can be avoided the waste of the energy in meeting need of production, overcome the shortcoming that traditional water injection vacuum pump can not regulate aqueous jet amount and flow velocity, avoided the waste of energy.
A kind of adjusting water ejector vacuum pump, comprises pump case, it is characterized in that: also comprise nozzle body, cam mechanism, nozzle slide block, sub-nozzle.The basic principle of adjusting water ejector vacuum pump work is: drive nozzle slide block to move by cam mechanism, the jet size forming on nozzle slide block and nozzle body is changed, reach the object that regulates jet size.
A kind of adjusting water ejector vacuum pump, is characterized in that: sub-nozzle is that annular is equally distributed, and the size of sub-nozzle opening size, by the nozzle slide block synchronization regulation that can move radially, realizes the controllability of nozzle flow and flow velocity.
The innovative point of this invention is: in water injection vacuum pump, adopt the adjustable nozzle of adjustable flow velocity and flow, by regulating flow and the flow velocity of nozzle, the degree of vacuum of its generation and flow and actual production are adapted, avoid the waste of redundant energy; Degree of vacuum that can be according to actual needs sprays at intelligent water speed and the flow of in vacuum condensation system, adjusting water injection vacuum pump nozzle in good time, makes it only produce required degree of vacuum, avoids producing redundant energy, reaches significantly energy-conservation object.

Embodiment
Describe embodiments of the present invention in detail below in conjunction with accompanying drawing:
Adjusting water ejector vacuum pump of the present invention, comprises pump case 1, nozzle body 2, cam mechanism 3, nozzle slide block 4, sub-nozzle 5, and the sub-nozzle 5 of adjusting water ejector vacuum pump is that annular is equally distributed.The Principles of Regulation of adjusting water ejector vacuum pump are: by cam mechanism 3, synchronously drive nozzle slide block 4 to move, the size of the sub-nozzle 5 forming on nozzle slide block and nozzle body 2 is changed, realize the controllability of nozzle flow and flow velocity.The present invention is applied in intelligent water and sprays in vacuum condensation system, and the circulating water in system enters adjusting water ejector vacuum pump along the water inlet direction of adjusting water ejector vacuum pump, and water is along the outlet end ejection of sub-nozzle 5.In the time that the quantity of circulating water in system changes according to actual production, cam mechanism 3 can be according to rotating clockwise or counterclockwise, the cam profile of cam mechanism 3 moves along the non-concentric circle guide groove of nozzle slide block 4, promoting nozzle slide block 4 radially moves, change sub-nozzle 5 sizes, reach the object that regulates flow velocity and flow.
The present invention also can use at traditional non intelligent type water and spray in vacuum vaporation system, obtains required degree of vacuum by the regulating action of water jet pump, changes the mode that regulates degree of vacuum by direct-connected atmosphere.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention; make without departing from the inventive concept of the premise some alternative or obvious modification that are equal to; and performance or purposes identical, should be considered as belonging to the definite protection domain of claims that the present invention submits to.
