Abstract

The utility model discloses an open type fluid boosting device, which comprises an enlarging pipe, a reducing pipe, a casing pipe, a Laval boosting spray pipe, an incremental pipe, a regulating valve and a one-way valve. The Laval boosting spray pipe is mounted inside the casing pipe, the enlarging pipe mounted at the front end of the casing pipe is radially communicated with the Laval boosting spray pipe, and the reducing pipe mounted at the tail end of the casing pipe is radially communicated with the tail end of the Laval boosting spray pipe. The enlarging pipe is communicated with the reducing pipe via the incremental pipe, the regulating valve and the one-way valve are arranged on the incremental pipe, and the open type fluid boosting device is mounted at a water outlet position of a circulating pump. The open type fluid boosting device with simple structure can form instant high pressure after being mounted at an outlet of the circulating pump and boost fluid, and boosted pressure can replace partial delivery lift of the circulating pump, thereby the boosting device lowers power of the circulating pump and achieves the purposes of electricity saving and consumption reduction.

Description

A kind of open fluid pressurized device

Technical field

The utility model relates to fluid pressurized device technique field, is meant a kind of open fluid pressurized device that is applied to the industrial colling circulating pump system especially.

Background technique

At present, national power consumption sharply increases sharply, and causes the imbalance between supply and demand of commercial power and household electricity, and is required for satisfying life, generally takes the power cuts to limit consumption to industrial enterprise, and this brings about great losses undoubtedly to industrial enterprise.And in industrial enterprise the circulation extraction system of the industrial colling nothing but of general power consumption maximum, particularly have 4.5 meters recycle pumps with interior suction journey.The configuration parameter of tradition circulating pump system is to dispose by system's institute's cooling or long-pending calculating of hot side, the flow of motor is directly proportional with the area of cooling or heat in the recycle pump parameter, lift mainly overcomes resistance of pipe system, pump capacity is constant keeping, lift is high more, the power of motor that is equipped with is also just high more, and the electric energy of electrical consumption is also just high more.The appearance of fluid pressurized device has reduced closed circulation system such as the central air-conditioning system power consumption, but for the open circulating pump system of industrial enterprise's cooling water, does not have corresponding with it pressure structure.Along with expanding economy, power supply is more and more nervous, and the high energy consumption of powerful motor has not only increased operation cost, does not also meet energy-saving and cost-reducing themes of the times.

Summary of the invention

The purpose of this utility model is to provide a kind of fluid pressurized device that is applied to the industrial colling circulating pump system, keeping under the constant situation of pump capacity, improve lift, reduce the open fluid pressurized device that power of motor and then realization cut down the consumption of energy simultaneously again.

For realizing the purpose of this utility model, intend by the following technical solutions:

A kind of open fluid pressurized device, dwindling pipe, a sleeve pipe, a Laval supercharging jet pipe, an incremental pipe, a modulating valve and an one-way valve by an amplifying tube, forms, it is characterized in that: described Laval supercharging jet pipe is installed in the inside of sleeve pipe, amplifying tube is installed in the front end of sleeve pipe, and be connected with Laval supercharging jet pipe diametrically, dwindle the end that pipe is installed in sleeve pipe, and with the terminal radial communication of Laval supercharging jet pipe.Amplifying tube and dwindle pipe and communicate by incremental pipe, and incremental pipe is provided with modulating valve and one-way valve.

Described open fluid pressurized device is installed in the water outlet place of recycle pump, after fluid enters amplifying tube, enlarges the cross section of fluid in amplifying tube, carries out supercharging by Laval supercharging jet pipe convection cell again under the situation of negative pressure, realizes the purpose of supercharging.When overpressure or flow are too low, after modulating valve by incremental pipe and one-way valve valve are regulated pressure and flow, enter again and dwindle in the pipe, and enter in the outside ductwork after converging with main fluid.The setting of one-way valve is for preventing the effect of backwater.

Compared with prior art, the utility model is simple in structure, reduce production costs, and, after the utility model is installed in outlet of circulating pump, can form the high pressure of a moment, and convection cell carries out supercharging, institute's pressurized energy can substitute the part lift of recycle pump, thereby has reduced the power of recycle pump, reaches the purpose of economize on electricity consumption reduction.

Description of drawings

Fig. 1 is the utility model embodiment's a structural drawing.

Label among the figure is: 1, amplifying tube; 2, dwindle pipe; 3, sleeve pipe; 4, Laval supercharging jet pipe; 5, incremental pipe; 6, modulating valve; 7, one-way valve.

Embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

Fig. 1 has illustrated the utility model embodiment's structure, the open fluid pressurized device of the utility model, be installed in the water outlet place of recycle pump, dwindling pipe 2, one sleeve pipe 3, a Laval supercharging jet pipe 4, one incremental pipe 5, a modulating valve 6 and an one-way valve 7 by an amplifying tube 1, forms, described Laval supercharging jet pipe 4 is installed in the inside of sleeve pipe 3, amplifying tube 1 is installed in the front end of sleeve pipe 3, and be connected with Laval supercharging jet pipe 4 diametrically, dwindle the end that pipe 2 is installed in sleeve pipe 3, and with the terminal radial communication of Laval supercharging jet pipe 4.Amplifying tube 1 and dwindle pipe 2 and communicate by incremental pipe 5, and incremental pipe 5 is provided with modulating valve 6 and one-way valve 7.When overpressure or flow are too low, after modulating valve 6 by incremental pipe 5 and one-way valve 7 are regulated pressure and flow, enter again and dwindle in the pipe 2, and enter in the outside ductwork after converging with main fluid.The setting of one-way valve 7 is for preventing the effect of backwater.By the effect of this supercharging device, can substitute the part lift of recycle pump, when reducing circulation pump power greatly, also reached same required lift.Reduce the power of recycle pump, also just reduced power consumption, realized energy saving purposes.

At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above examples of implementation, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
