Description
Technical field
The present invention relates to a kind of high-pressure water gun power, belonged to electronic technology field.
Background technology
The water of giant is provided by high-pressure hydraulic pump, the quality of motor directly affects the pressure of hydraulic giant, and the frequency of utilization of giant is very high, switches frequently between standby and work two states, workload is very large, thereby causes giant often to break down.
When giant of the prior art has operating state to switch to holding state; electronic electric current and rotating speed all can reduce to rapidly zero; then the hydraulic pressure of water pump not only can not descend; have on the contrary rising to a certain degree; thereby when causing giant to switch to operating state from holding state; the motor of giant needs high capacity to start; and starting current is large; cause the regular damage of thermal protector and pressure switch; and the life-span of the motor of giant also can shorten greatly; so not only cause the significantly increase of production cost, and can have a strong impact on the production efficiency of enterprise.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high-pressure water gun power, realizes that the low load of giant motor starts, and greatly prolongs the useful life of giant, improves the fail safe when using giant.
The technical solution adopted in the present invention is: a kind of high-pressure water gun power, comprise three-terminal polarized plus plug J1 and giant, it is characterized in that: also comprise mains switch J2, starting switch S1, A.C. contactor, solid-state relay J3, the solenoid of described three-terminal polarized plus plug J1 and mains switch J2, starting switch S1, A.C. contactor forms series loop; The auxiliary contact of described A.C. contactor are connected with the output contact of solid-state relay J3, the motor in series of giant; The input of described solid-state relay J3 and 5V DC power supply, giant sensitive switch S2 form series loop.
Aforesaid high-pressure water gun power is characterized in that: also be in series with a hot protective relay between described starting switch S1 and the A.C. contactor.
Aforesaid high-pressure water gun power is characterized in that: also be in series with pressure switch P between described starting switch S1 and the A.C. contactor.
Aforesaid high-pressure water gun power is characterized in that: also comprise a motor power indicator light in parallel with the giant motor.
Aforesaid high-pressure water gun power is characterized in that: aluminium seat type radiating fin is installed on the described solid-state relay.
Aforesaid high-pressure water gun power is characterized in that: described aluminium seat type radiating fin is provided with a plurality of perforates.
Aforesaid high-pressure water gun power is characterized in that: on the described aluminium seat type radiating fin radiator fan is installed.
The invention has the beneficial effects as follows: the power control circuit by improving giant and the starting switch of giant; once a plurality of circuit protection modules had been added; the low load that has realized the giant motor starts; prolonged the useful life of equipment, the fail safe of its power circuit has also obtained the raising of arriving very much.
Description of drawings
The circuit connection diagram of Fig. 1 giant power control part;
The analysis chart of motor pressure, rotating speed and electric current during the work of Fig. 2 giant.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of high-pressure water gun power, comprise three-phase socket J1 and giant, also comprise mains switch J2, starting switch S1, A.C. contactor, solid-state relay J3, the solenoid of described three-terminal polarized plus plug J1 and Switching Power Supply J2, starting switch S1, A.C. contactor forms series loop; The auxiliary contact of described A.C. contactor are connected with the output contact of solid-state relay J3, the motor in series of giant; The input of described solid-state relay J3 and 5V DC power supply, giant sensitive switch S2 form series loop; Stuck for preventing the hydraulic giant sensitive switch, water pump is always in running order, also is in series with hot protective relay and pressure switch P between starting switch S1 and A.C. contactor; Whether the LED light in parallel with the giant motor can be in normal operating conditions by the alert giant.
With three-terminal polarized plus plug J1 plugged, after high-pressure hydraulic pump connects the water source, mains switch J2 and starting switch S1, the solenoid conducting of A.C. contactor, auxiliary contact closure, thus make the motor of giant be in holding state.
Press the sensitive switch S2 of giant, thereby make the input conducting of solid-state relay J3, output contact is closed, makes the motor of giant in running order.Because the sensitive switch of giant need to could conducting by on earth the time with the hydraulic giant trigger, like this, just open fully in the water route of hydraulic giant, when the hydraulic giant trigger disconnects, only needs trigger is returned a bit slightly, the sensitive switch of hydraulic giant just disconnects, motor is just out of service, and at this moment hydraulic pressure almost can be discharged to minimum point, therefore, be not have pressure in the pump chamber of motor and water pump, can realize low voltage starting thereby motor was started in next time.
The motor speed of giant, electric current and the hydraulic pressure Dynamic Variation Analysis figure under standby and work two states as shown in Figure 2.
When equipment is short-circuited or electric wire when catching fire, electric leakage protection relay J2 can trip reliably, and the protection person fully.
Solid-state relay J3 can generate heat during work, will damage if temperature continues rising, therefore at solid-state relay aluminium seat type radiating fin is installed, and is provided with a plurality of perforates at aluminium seat type radiating fin, and radiator fan is installed.
In sum; high-pressure water gun power provided by the invention by improving giant power control circuit and the starting switch of giant; once a plurality of circuit protection modules had been added; the low load that has realized the giant motor starts; prolonged the useful life of equipment, the fail safe of its power circuit has also obtained the raising of arriving very much.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
