Abstract
The utility model discloses a steam jetting pump with an adjustable nozzle. The steam jetting pump comprises a jetting pump shell, a nozzle and a steam chamber, wherein the nozzle is connected with the jetting pump shell in a sealing way; the steam chamber is fixedly connected with the nozzle; the jetting pump shell is fixedly connected with an adjusting screw rod which is parallel to the jetting pump shell and passes through a flange arranged on the steam chamber; and the adjusting screw rod is connected with a nut which is locked at both sides of the flange. The nozzle can be adjusted as needed along the axis direction of the jetting pump by controlling the position of the steam chamber on a locating screw; when operating conditions such as the pressure, temperature, flow and the like of working steam changes, the nozzle can be adjusted to ensure the jetting pump to work at the optimum point and cause a system to stably operate under variable working conditions, thus effectively ensuring the stable running capability of the jetting pump under the variable working conditions, improving the utilization efficiency of the working steam and increasing the operational capability of a low-temperature multi-effect seawater desalination plant under variable working conditions.
Description
Technical field
The utility model relates to a kind of vapor pump, the adjustable vapor pump of particularly a kind of nozzle location.
Background technique
Low-temperature multi-effect seawater desalination device is imported with a certain amount of steam, by repeatedly part evaporation and condensation, realizes higher steam utilization efficient.Vapor pump can compress the Low Temperature Steam that certain 1st effective evaporator evaporation in the low-temperature multi-effect seawater desalination device obtains, after improving its temperature, re-enter system, realize the recycling of low-grade steam, the water generation ratio of elevator system, supporting have the water generation ratio of the low-temperature multi-effect seawater desalination device of jet pump (TVC) will be apparently higher than the device that does not have supporting TVC pump.Jet pump has become one of critical component of low-temperature multi-effect seawater desalination device.
Jet pump mainly is made up of injection pump housing and nozzle two-part.At present, the nozzle of the vapor pump of using in the low-temperature multiple-effect seawater desalination system (TVC) device is fixed on the injection pump housing, and the fixed-site of nozzle in jet pump is unadjustable.The fixing jet pump of this nozzle location can only move under design conditions, and the variable working condition conformability is poor, and when there was variation in actual conditions with design load, very big deterioration will appear in its service behaviour, can cause the whole system can not stable operation.
Summary of the invention
The utility model provides a kind of nozzle location adjustable vapor pump for solving the technical problem that exists in the known technology, when being used for realizing that the operation operating mode changes, by regulating nozzle location, improves the jet pump service behaviour, guarantees the stable operation of system.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the vapor pump that a kind of nozzle location is adjustable, comprise injection pump housing, be connected nozzle on the described injection pump housing and the vaporium affixed with described nozzle, described nozzle and described injection pump housing are tightly connected, be connected with adjusting screw rod in parallel on the described injection pump housing, described adjusting screw rod passes the flange that is provided with on the described vaporium, is connected with the nut that is locked at described flange both sides on the described adjusting screw rod.
Be connected by packing seal between described nozzle and the described injection pump housing.
Described adjusting screw rod is by being threaded on the described injection pump housing.
Described adjusting screw rod is welded on the described injection pump housing.
Described adjusting screw rod is at least two, and all adjusting screw rods are circumferentially evenly arranged along described flange.
Advantage and the good effect that the utlity model has are: adopt nozzle to be fixed on the vaporium, rather than be fixed on structure on the injection pump housing, by the position of control vaporium on positioning screw, realize the purpose that nozzle location can be regulated along the jet pump axial direction as required, when the operation operating mode, the pressure of working steam for example, temperature, when flows etc. change, can be by regulating nozzle location, guarantee that jet pump is in optimum work, the stable operation of realization system under variable working condition, guaranteed the stable operation ability of jet pump under the variable working condition situation effectively, improve the utilization ratio of working steam, promoted the Off-design operation ability of low-temperature multi-effect seawater desalination device.And the utility model is simple in structure, is convenient to operation.The utility model is not only applicable to low-temperature multi-effect seawater desalination device, also can be used for fields such as chemical industry, iron and steel, refrigeration, food.

Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, vaporium, 2, screw rod, 3, back nut, 4, preceding nut, 5, the nozzle gland, 6, nozzle, 7, Gland, 8, filler, 9, Stuffing box, 10, injection pump housing, 11, pad.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the vapor pump that a kind of nozzle location of the utility model is adjustable is made up of injection pump housing 10, nozzle 6, vaporium 1, adjusting screw rod 2 and seal arrangement five parts.Nozzle gland 5 is fixed on nozzle 6 on the vaporium 1, uses Bolt Connection between nozzle gland 5 and the vaporium, between vaporium 1 and the nozzle 6 pad 11 is housed, and seals.Nozzle 6 front ends stretch in the injection pump housing 10, closely cooperate between Stuffing box 9 bottoms on the housing 10 and the nozzle 6, play the guiding role.Leave enough spaces between Stuffing box 9 middle parts and the nozzle 6, the filler 8 usefulness Glands 7 of packing into compress, and avoid producing between Stuffing box 9 and the nozzle 6 and reveal.Be connected with bolt between Gland 7 and the Stuffing box 9.Fixing between screw rod 2 and the Stuffing box 9 by screw thread or welding, screw rod 2 passes the through hole on vaporium 1 front end flange, and back nut 3 and preceding nut 4 be housed before and after vaporium 1 front end flange, the controlling mechanism that screw rod 2, back nut 3 and preceding nut 4 constitute can be that two groups of symmetries or many groups evenly distribute.
With nozzle location timing to the right, earlier the preceding nut 4 on each screw rod is screwed to specified position to housing 10 directions, then the back nut on each screw rod 3 is screwed to same direction, promote vaporium and move towards same direction, compress until vaporium front end flange face and preceding nut 4, finish adjusting.
With nozzle location timing left, earlier back nut 3 to be screwed to specified position to vaporium 1 direction, nut 4 before screwing in the same direction then compresses vaporium front end flange and back nut 3, finishes adjusting.
The vapor pump of said structure, nozzle and injection pump housing are separate, and nozzle is fixed on the vaporium, can change with the change of vaporium position.Be connected by screw rod between vaporium and the injection pump housing, its characteristics are, by the position of vaporium on screw rod, location, realize the adjusting of nozzle location.Be provided with seal arrangement between nozzle and the injection pump housing, the sealability in the adjusting of assurance jet pump, the running between jet pump and the injection pump housing.
