Abstract
The utility model relates to a membrane life-test rack which comprises a water tank, a water pump, a programmable logic controller (PLC) circuit, an electromagnetic valve I, an electromagnetic valve II, a cable conductor and a pipeline. The working principle of the membrane life-test rack is as follows: the water pump pumps water in the water tank to a to-be-tested water pump pressure controller with a membrane; after passing through the to-be-tested water pump pressure controller with the membrane, the water flow runs back to the water tank via the pipeline; the PLC circuit is connected with the electromagnetic valve I and the electromagnetic valve II respectively through the cable conductor; when the electromagnetic valve I is powered on, the water flow enters the to-be-tested water pump pressure controller with the membrane via the pipeline; when the electromagnetic valve I is powered off, the water flow can not enter the to-be-tested water pump pressure controller with the membrane via the pipeline; and when the electromagnetic valve II is powered on, the water flow runs back to the water tank via the pipeline after passing through the to-be-tested water pump pressure controller with the membrane. The scheme disclosed by the utility model is high in automaticity and efficiency.
Description
Technical field
The utility model relates to the diaphragm life-test rack in the life-span of the diaphragm that a kind of automaticity height, test water pump pressure on-off controller that efficient is high use.
Background technology
The water-aspirator pressure on-off controller be a kind of very important components and parts in the water source automation field, and the diaphragm in the water-aspirator pressure on-off controller is critical component, must carry out life test to it.The life test of diaphragm makes diaphragm deformation and restoring action for to carry out break-make hydraulic pressure to diaphragm; Check after test is good diaphragm whether be out of shape excessive, ftracture and penetrate.By testing 100,000 times, do not note abnormalities, then judge test passes.In the past, the water-aspirator pressure on-off controller was directly placed a water pump and a panel box at large water tank doing when test in life-span, then the water-aspirator pressure on-off controller was installed on the water pump, and feed pump is poured water again, starts at last, begins test.This method of testing, efficient is low, and the labor strength height.
The utility model content
The utility model purpose is the diaphragm life-test rack that the life-span of the diaphragm that a kind of automaticity height, test water pump pressure on-off controller that efficient is high use is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of diaphragm life-test rack comprises water tank, water pump, PLC control circuit, solenoid valve 1, solenoid valve 2, cable, pipeline; Described water pump by pipeline from drawing water in the water tank to tested band diaphragm water-aspirator pressure controller; Current by tested band diaphragm water-aspirator pressure controller after reflow tank by the road again; Described PLC control circuit links to each other with solenoid valve 1, solenoid valve 2 respectively by cable; When solenoid valve 1 when electric, current can enter tested band diaphragm water-aspirator pressure controller through pipeline; When solenoid valve 1 dead electricity, current can not enter tested band diaphragm water-aspirator pressure controller through pipeline; When solenoid valve 2 when electric, current by tested band diaphragm water-aspirator pressure controller after reflow tank by the road again.
Preferably, described pipeline is provided with a plurality of stations, so that the one-shot water pump can be tested a plurality of tested band diaphragm water-aspirator pressure controllers.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The described diaphragm life-test rack of the utility model scheme, realize water pump control by PLC control circuit control solenoid valve 1, solenoid valve 2, to reach diaphragm is carried out the break-make hydraulic pressure test, the utility model is incorporated into all devices on the test board, and a plurality of stations are installed can be tested simultaneously, only need during test the product station of screwing on just can be tested by beginning; The utility model scheme automaticity height, efficient height.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the fundamental diagram of diaphragm life-test rack described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is diaphragm life-test rack described in the utility model, comprises water tank, water pump, PLC control circuit, solenoid valve 1, solenoid valve 2, cable, pipeline; Described water pump by pipeline from drawing water in the water tank to tested band diaphragm water-aspirator pressure controller; Current by tested band diaphragm water-aspirator pressure controller after reflow tank by the road again; Described PLC control circuit links to each other with solenoid valve 1, solenoid valve 2 respectively by cable; When solenoid valve 1 when electric, current can enter tested band diaphragm water-aspirator pressure controller through pipeline; When solenoid valve 1 dead electricity, current can not enter tested band diaphragm water-aspirator pressure controller through pipeline; When solenoid valve 2 when electric, current by tested band diaphragm water-aspirator pressure controller after reflow tank by the road again; Described pipeline is provided with 9 stations, so that the one-shot water pump can be tested 9 tested band diaphragm water-aspirator pressure controllers.
The described diaphragm life-test rack of the utility model scheme, realize water pump control by PLC control circuit control solenoid valve 1, solenoid valve 2, to reach diaphragm is carried out the break-make hydraulic pressure test, the utility model is incorporated into all devices on the test board, and a plurality of stations are installed can be tested simultaneously, only need during test the product station of screwing on just can be tested by beginning; The utility model scheme automaticity height, efficient height.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
