Abstract
The utility model relates to a flow switch detection device, its characterized in that includes hydraulic pump (1), first pilot lamp (3), second pilot lamp (4), liquid reserve tank (6) and shaking table (7), flow switch (2) are fixed on shaking table (7), hydraulic pump (1), flow switch (2) and liquid reserve tank (6) constitute the liquid circulation return circuit through connecting tube (5), first pilot lamp (3) are connected through wire and flow switch's normally closed output terminal (21) and public output terminal (23) electricity, second pilot lamp (4) are connected through wire and flow switch's normally open output terminal (22) and public output terminal (23) electricity, external power source is connected in flow switch input terminal (24). The utility model discloses owing to utilize flow switch's double key switch function, can judge flow switch's life through pilot lamp state change time, utilize the vibration of shaking table to more press close to flow switch's operational environment, make the life who detects more accord with the environmental requirement.
Description
Technical field
The utility model is a kind of flow switch pick-up unit, particularly a kind of flow switch pick-up unit that can detect serviceable life the flow switch in the vibration environment that jolts.
Background technology
On engineering machinery and special operation vehicle, often use the electronic component flow switch, effective work of flow switch plays significant effects to the lean on property and the stability of its equipment, therefore the detection to the flow switch Acceptable life becomes important all the more, but the detection in flow switch serviceable life in the vibration environment that jolts is also lacked corresponding means and method at present.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming and the flow switch pick-up unit that can detect serviceable life the flow switch in the vibration environment that jolts is provided.This utility structure is simple, and is convenient and practical.
Structural representation of the present utility model as shown in drawings, comprise hydraulic pump, first pilot lamp, second pilot lamp, liquid reserve tank and shaking table, flow switch is fixed on the shaking table, hydraulic pump, flow switch and liquid reserve tank are formed liquid circulation loop by connecting tube, first pilot lamp is electrically connected with the normally closed lead-out terminal and public output of flow switch by lead, second pilot lamp by lead and flow switch often open lead-out terminal and public output is electrically connected, flow switch input terminal connection external power source.
The utility model is owing to utilize the double-button switch function of flow switch, can judge the serviceable life of flow switch by the led status transformation period, utilize the vibration of shaking table more to press close to the working environment of flow switch, make more to meet environmental requirement the serviceable life that detects.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1, comprise hydraulic pump 1, first pilot lamp 3, second pilot lamp 4, liquid reserve tank 6 and shaking table 7, flow switch 2 is fixed on the shaking table 7, hydraulic pump 1, flow switch 2 and liquid reserve tank 6 are formed liquid circulation loop by connecting tube 5, first pilot lamp 3 is electrically connected with the normally closed lead-out terminal 21 and public output 23 of flow switch by lead, second pilot lamp 4 by lead and flow switch often open lead-out terminal 22 and public output 23 is electrically connected, flow switch input terminal 24 connects external power source, and the circuit theory road as shown in Figure 2.
Detection method of the present utility model is as follows: when connecting flow switch connection external power source, the double-button switch in the flow switch is in normally off, first pilot lamp " bright ", and second pilot lamp " goes out "; Open the hydraulic pump power supply, hydraulic pump is started working, and from liquid reserve tank suction flow switch, liquid is got to Chang Kaijian to double-button switch on one side during by flow switch liquid, and first pilot lamp " is gone out " by " bright " change, and second pilot lamp is by " going out " change " bright "; When the hydraulic pump operate as normal, and first pilot lamp is in " bright " state, and when second pilot lamp was in " going out " state, the expression flow switch may damage, by the transformation period of first and second led status, just can detect the serviceable life of flow switch like this; In addition, because of flow switch is fixed on the shaking table, Vibration on Start-up platform under the normal situation of flow switch is observed time of first and second pilot lamp " bright " and " going out " in the continuous shaking process, just can the analogue flow rate switch serviceable life in the vibration environment that jolts.
