Abstract
The utility model relates to a pressure testing platform of a heat exchanger. The pressure testing working platform comprises a water tank, a filter, a pressure testing pump and an overflow valve, wherein a water absorption pipe of the pressure testing pump is connected into the water tank, a water outlet of the pressure testing pump is connected with an inlet pipe, an inlet pipe valve is arranged on the inlet pipe and divided into a loop pipe and a plurality of branch pipes after being connected with the inlet pipe valve, and an outlet of the loop pipe is connected into the water tank; a loop pipe valve and a branch pipe valve are respectively arranged on the loop pipe and each branch pipe, and the pressure testing pump is a stepless adjustable pressure pump; and the tail end of the water absorption pipe of the pressure testing pump or the tail end of the outlet of the loop pipe are both connected with the filter. The pressure testing platform of the heat exchanger has the advantages that pressure testing is performed on a plurality of heat exchangers simultaneously by dividing the inlet pipe into the plurality of branch pipes; cyclic utilization of water resources during pressure testing is achieved by additionally adding the loop pipe in the platform; and cost is saved.
Description
Technical field
The utility model relates to a kind of work pressure test platform of heat interchanger, is applicable to treat that to many heat interchanger of factory inspection carries out the workplace of pressure testing test simultaneously.
Background technology
Heat interchanger will carry out pressure testing before using, the pressure testing system of heat interchanger is comprised of heat interchanger, test pump, metal hose, tensimeter, blind plate and pressure testing ring etc.Pressure testing is looked for Lou, and workflow is divided into following operation steps: isolation-connecting line-water-filling boosts-voltage stabilizing-search leak source-release discharge water-leak stopping-water-filling boosts-voltage stabilizing-draining-restoring scene.According to site specific, the maximum design pressure and the official hour that provide according to production unit carry out voltage stabilizing, after occurring leaking without any tube bank again within the voltage stabilizing time, will be judged to be and finish pressure testing leak stopping work success.
Release each time discharge water and last drainage technology in, how to improve the recycling efficient of test water, be a technical matters that merits attention.In addition, the making of pressure testing process, design will have certain versatility, only be not confined in the pressure testing test to Heat Exchanger, can realize the pressure testing test to many heat interchanger simultaneously for satisfying heat interchanger manufacturer, improve the pressure testing detection efficiency, invent a kind of energy and realize that the heat interchanger of simultaneously many assemblings being finished carries out the workbench that pressure testing detects, and can save the test water, reduce water resources consumption, the production cost that reduces enterprise is had great meaning.
The utility model content
The purpose of this utility model provides a kind of work pressure test platform of heat interchanger, can realize many heat interchanger are carried out the pressure testing test by this platform, and can realize testing the recycling of water.
The technical scheme that realizes the utility model purpose is: a kind of heat interchanger work pressure test platform comprises water tank, test pump and surplus valve; It is characterized in that: in the suction hose access water tank of described test pump, the water delivering orifice of described test pump is connected to the route pipe; Described route pipe is provided with the route tube valve, and described route pipe bifurcated after connecting described route tube valve is a loop pipe and some take-off pipes; The outlet of described loop pipe accesses in the described water tank; Described loop pipe and described take-off pipe are provided with loop pipe valve and take-off pipe valve.
Described test pump is stepless adjustable pressure pump.
The terminal filtrator that connects of the suction hose of described test pump outlet terminal or described loop pipe.
The utlity model has positive effect: by induction pipe being divided into some take-off pipes, pressure testing test when having realized many heat interchanger; By in platform, setting up a loop pipe, realized recycling to water resource in the pressure testing process, saved cost.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings.
Fig. 1 is hydraulic schematic diagram of the present utility model.
Fig. 2 implements structural representation of the present utility model.
Among the figure, 1 water tank, 2 filtrators, 3 test pumps, 4 loop pipe valves, 5 route tube valves, 6 loop pipe, 7 route pipes, 8 surplus valves, 9 take-off pipes, 10 branching valves, 11 heat interchanger imports, 12 heat exchanger exits.
Embodiment
See Fig. 1, the utlity model has water tank 1, filtrator 2, test pump 3 and surplus valve 8, test pump 3 preferred stepless adjustable pressure pumps, surplus valve 8 and test pump 3 safety that are used for guaranteeing whole system pressure in parallel; The suction hose of test pump 3 is provided with filtrator 2, test pump 3 water delivering orifices are connected to the route pipe, 7, route pipe 7 is provided with route tube valve 5, route pipe 7 is a loop pipe 6 and some take-off pipes 9 connecting route tube valve 5 rear bifurcateds, in the outlet access water tank 1 of loop pipe 6, its exit is connected with filtrator 2; Loop pipe 6 and every take-off pipe 9 are provided with loop pipe valve 4 and take-off pipe valve 10.
As shown in Figure 2, a heat interchanger is accessed this work pressure test platform, the pressure testing operating process is as follows, and a heat interchanger import 11 is linked to each other with the outlet of a take-off pipe 9, and the outlet 12 of heat interchanger keeps closing; Open route tube valve 5 and take-off pipe valve 10, close loop pipe valve 4; Open test pump 3, the water in the water tank 1 finally enters heat interchanger inside by heat interchanger import 11 by test pump 3 from route pipe 7 take-off pipe 9 of flowing through, because heat exchanger exit 12 closes, so form certain hydraulic pressure in that heat interchanger is inner, the hydraulic testing begins.
In the time the water in the heat interchanger need to being discharged, only need close test pump 3 and route tube valve 5, open loop pipe valve 4 and take-off pipe valve 10; Gases at high pressure are passed into heat exchanger exit 12, and the water in the heat interchanger will be under the effect of gases at high pressure 9 flow in the loop pipe 6 from heat interchanger import 11 along take-off pipe, because therefore the outlet of loop pipe 6 access water tank 1 has realized the recycling of water resource.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
