Description
Technical field
The utility model belongs to the air pressure technical field of measurement and test, is specifically related to a kind of portable filter core detecting device.
Background technology
The filter core of filtered fluid need carry out the air pressure test to filter core when dispatching from the factory; Whether the test filter core is qualified; Employable filter core does not go to use; With the waste that causes filter core, obsolete filter core goes to use the particle that will make system to increase, and the stability of the filtering system of destruction, causes the damage of various Hydraulic Elements.The mode of doing experiment with the filter core tradition is to utilize about the low-pressure air 0.5MPa of factory, and not only insufficient pressure is enough big but also the test data out of true for this, and each test all need be reinstalled testing tool, and the test step trouble is used quite inconvenience.
The utility model content
The utility model provides a kind of easy to use, simple to operate, accurate portable filter core detecting device of test data in order to solve weak point of the prior art.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: portable filter core detecting device; Comprise detection receptacle and the rapid-acting coupling, tensimeter test suite, flowmeter test suite, vent valve, pressure regulator valve, first reduction valve and the retaining valve that connect through high-pressure air pipe successively; The air intake opening of said retaining valve is parallel with gas cylinder feeder and air pump feeder, and the air intake opening place of retaining valve is connected with tensimeter, and rapid-acting coupling is connected with the filter core draft tube; The gas outlet of filter core draft tube extend in the detection receptacle, is loaded with kerosene in the detection receptacle.
Said gas cylinder feeder is second reduction valve, air filter assembly, air inlet switch and the gas cylinder joint that is connected with check valve inlet successively.
Said air pump feeder is pneumatic triple piece and the micro air pump that is connected with check valve inlet successively, and micro air pump is connected with plug and accumulator through lead respectively.
Adopt technique scheme, filter core is connected with the gas outlet of rapid-acting coupling, be placed under the kerosene liquid level in the detection receptacle; Use the gas cylinder feeder to do source of the gas, can directly carry out the air feed test through gas cylinder joint connection nitrogen or welding bottle, like this can be without the low-pressure air of 0.5Mpa in the factory; Under the situation that does not have source of the gas; Can plug be inserted on the charged socket, perhaps not have under the situation of power supply, use accumulator power supply to be provided as the air pump feeder; The air pump feeder provides low-pressure air, satisfies the detection requirement of filter core.In testing process, the numeric ratio that utilizes tensimeter test suite, flowmeter test suite data presented and filter core regulation, and range estimation filter core whether bubbling in kerosene, whether measure filter core qualified.The utility model principle science, simple in structure, easy to use, simple operation, it is wide to be suitable for the aspect, and test data is accurate, and whether qualified, guaranteed the ex factory pass rate of filter core effectively if accurately detecting the number filter core.
Description of drawings
Fig. 1 is the principle schematic of the utility model.
Embodiment
As shown in Figure 1; The portable filter core detecting device of the utility model; Comprise detection receptacle 17 and the rapid-acting coupling 2, tensimeter test suite 3, flowmeter test suite 4, vent valve 5, pressure regulator valve 6, first reduction valve 7 and the retaining valve 8 that connect through high-pressure air pipe 1 successively; The air intake opening of retaining valve 8 is parallel with gas cylinder feeder and air pump feeder, and the air intake opening place of retaining valve 8 is connected with tensimeter 9, and rapid-acting coupling 2 is connected with filter core draft tube 16; The gas outlet of filter core draft tube 16 extend in the detection receptacle 17, is loaded with kerosene 18 in the detection receptacle 17.
The gas cylinder feeder is second reduction valve 10, air filter assembly 11, air inlet switch 12 and the gas cylinder joint 13 that is connected with retaining valve 8 air intake openings successively.The air pump feeder is the pneumatic triple piece 14 and micro air pump 15 that is connected with retaining valve 8 air intake openings successively, and micro air pump 15 is connected with plug 21 and accumulator 22 through lead 19 and lead 20 respectively.
When work is used, the gas outlet of filter core 23 with rapid-acting coupling 2 is connected, is placed under kerosene 18 liquid levels in the detection receptacle 17.
Use the gas cylinder feeder to detect; Directly gas cylinder joint 13 is connected nitrogen or welding bottle; Rapid-acting coupling 2 is connected with filter core draft tube 16, checks then whether pipeline leaks gas, and regulates first reduction valve 7 and second reduction valve 10 to suitable numerical value; Open air inlet switch 2; Then regulate pressure regulator valve 6 and observe filter core 23 reading of tensimeter test suite when coming out bubble 3 and flowmeter test suite 4, whether the numeric ratio of stipulating actual detected to value and filter core 23 decides filter core 23 qualified.
Under the situation that does not have source of the gas, use plug 21 to be inserted on the charged socket, be micro air pump 15 power supplies; Steps in sequence does; Rapid-acting coupling 2 is connected with filter core draft tube 16, checks then whether pipeline leaks gas, regulate first reduction valve 7 and second reduction valve 10 to suitable numerical value; Open micro air pump 15 air feed; Then regulate pressure regulator valve 6 and observe filter core 23 reading of tensimeter test suite when coming out bubble 3 and flowmeter test suite 4, whether the numeric ratio of stipulating actual detected to value and filter core 23 decides filter core 23 qualified.
When the place of detecting had not both had source of the gas not have under the situation of power supply yet, just use accumulator 22 to be micro air pump 15 power supplies.Filter core is detected step and uses plug 21 the same.
