Abstract
The zero load starting protection device of a kind of magic hand for spraying concrete oil hydraulic pump, it comprises oil hydraulic pump enable switch, time delay relay and load equipment, and this oil hydraulic pump enable switch is connected with this time delay relay, and this time delay relay is connected with this load equipment.So, installing additional by time delay relay, make magic hand for spraying concrete oil hydraulic pump (motor) start complete before (time delay relay setting starting time in), other any operation is all invalid, and can effectively guarantee the person and device security.
Description
Technical field
The utility model relates to magic hand for spraying concrete oil hydraulic pump (motor) starting protection device, is specifically related to carry out the device of safety protection to the person, equipment when a kind of oil hydraulic pump is zero load to be started.
Background technique
At present; when magic hand for spraying concrete oil hydraulic pump (motor) starts; there is no protective measure; if on control cabinet some switch not " closedown " position or oil hydraulic pump (motor) start complete before; operate the words of some action; the overpressure in accumulator can be caused, make oil hydraulic pump (motor) starting under load, thus easily jeopardize the person and equipment (load) safety.
Model utility content
Technical problem to be solved in the utility model is; for unprotect measure when magic hand for spraying concrete oil hydraulic pump (motor) starts in above-mentioned prior art; easily jeopardize the person and the deficiency of device security, a kind of safety and the reliable zero load starting protection device of magic hand for spraying concrete oil hydraulic pump are provided.
For solving the problems of the technologies described above; the technological scheme that the utility model adopts is: a kind of magic hand for spraying concrete oil hydraulic pump is zero load starting protection device; it comprises oil hydraulic pump enable switch and load equipment; it is characterized in that; also comprise time delay relay; this oil hydraulic pump enable switch is connected with this time delay relay, and this time delay relay is connected with this load equipment.
Compared with prior art, the beneficial effect that the utility model has is: installing additional by time delay relay, make magic hand for spraying concrete oil hydraulic pump (motor) start complete before (time delay relay setting starting time in), other any operation is all invalid, and can effectively guarantee the person and device security.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Embodiment
See Fig. 1; the utility model is the zero load starting protection device of a kind of magic hand for spraying concrete oil hydraulic pump; it comprises oil hydraulic pump enable switch 1, time delay relay 2 and load equipment 3; this oil hydraulic pump enable switch 1 is connected with this time delay relay 2, and this time delay relay 2 is connected with this load equipment 3.
So, utilize oil hydraulic pump (motor) enable switch 1 as signal source, when primer fluid press pump (motor), time delay relay 2 energized action starts timing, does not reach set time, and load equipment 3 can not normal running, when after the time reaching setting, just allow load equipment 3 normal running, otherwise any operation is all invalid, thus guarantees the person and device security.
