Water；Control circuit 23 is AND logic circuit, according to the progress of the needs of tester and logic judgment, is assigned by console 10
Agree to plus water order is to control circuit 23, control supply-water pump 3 starts to carry out adding water to the water tank 18 of high-low temperature test chamber 16.Work as height
During the water level of water tank 18 rise of low-temperature test chamber 16, float 15 puts on corkline with the rising of water level under buoyancy
26 pulling force disappears, and float transmission mechanism 14 produces downward thrust and to contact 20 movable control with fixed control panel originally
The contact of plate 21 moves down, and the movable contact of control panel 21 departs from fixed control panel 20, passes through feedback loop to control circuit 23
Feedback signal disappear, because control circuit 23 be "AND" logic, i.e., when fixed control panel 20 and the separation of movable control panel 21,
The output order of control circuit 23 stops supply-water pump 3 plus water.The limited block 17 defines corkline 26 in high-low temperature test chamber 16
Position and length in housing, the length by adjusting corkline can control the water level limit value that water shortage alerts.
The automatic watering apparatus for high-low temperature test chamber has water tank high voltage alarm and trouble handling function, specifically
For：When the water supply gate valve 19 of feed pipe 22 is closed and supply-water pump 3 is in 18 service position of water tank, enter along supply-water pump 3
Water in feed pipe 22 starts to increase pressure, and pressure gauge 9 monitors the change of hydraulic pressure in feed pipe 22, when the pressure value monitored
During higher than setting value, the high limit control signal of pressure produces in pressure gauge 9, by direct feedback loop to console 10, control
Platform 10 processed produces high voltage alarm, and the high voltage alarm on console 10 indicates that 36 lamps are bright, and buzzer 37 sends alarm call, and by straight
Connect backfeed loop control supply-water pump 3 to stop supplying water so that the water in cistern 4 stops entering feed pipe 3, effectively prevent water supply
When water supply gate valve 19 mistake close or feed pipe 22 blocks and causes inner pipe water pressure abruptly increase to cause pipe burst.When the pipe of feed pipe 22
When wall pressure power reduces, pressure gauge 9 monitors the change of water supply inner pipe water pressure, when the pressure value detected is recovered less than regulation high pressure
Pressure high limit control is produced during value, in pressure gauge 9 and recovers signal, feeds back to console 10, it is extensive that console 10 produces high limit control
Complex signal, high voltage alarm indicator lamp 36 extinguish, and buzzer 37 stops making sound.
As shown in figure 3, AC220V power supplys are via earth leakage protective device 31, and A.C. contactor 30（Linear quadratic control）Control is logical
It is disconnected, and set emergency stop switch 43 and cross flow fuse 29, in the case of the normal water supply of supply-water pump 3,30,31 contact closure, and
The second relay contact 39 and the 3rd relay contact 41 in console close, and supply-water pump 3 is obtained electric water supply.Meanwhile water pump
Relay indicating light 42 is lighted.When water level decreasing in the water tank 18 of high-low temperature test chamber 16, float 15 is made by transmission mechanism 14
The contact for obtaining movable control panel 21 moves up, and fixed control panel 20 contacts, and connects backfeed loop so that the 3rd relay coil 32
It is powered, the 3rd collector contact 33 corresponding to the 3rd relay coil 32 in console 10 closes, water shortage alarm indicator 34
Bright, buzzer 37 sends alarm call；23 control circuits are AND logic circuit, when tester agrees to add water, pass through conversion
When switch 44 connects loop, 23 control circuits are connected so that the 3rd relay coil 38 is powered, the correspondence of the 3rd relay coil 38
The 3rd relay contact 41 close so that ac contactor coil 40 is powered, and A.C. contactor 30 is connected, control supply-water pump 3
Start and the water tank 18 of high-low temperature test chamber 16 is carried out to add water.When the water supply gate valve 19 of feed pipe 22 is closed and supply-water pump 3 is in
During to 18 service position of water tank, the water entered along supply-water pump 3 in feed pipe 22 starts to increase pressure, and pressure gauge 9 monitors to supply
The change of hydraulic pressure in water pipe 22, when the pressure value monitored is higher than setting value, the high limit loop of pressure is connected in pressure gauge 9, is made
The second relay coil 35 obtained in console 10 is powered, and the second relay contact 39 corresponding to the second relay coil 35 is disconnected
Open, the generation high voltage alarm of console 10, the high voltage alarm indicator lamp 36 on console 10 is bright, and the second relay contact 39 disconnects
Afterwards, the dead electricity of ac contactor coil 40, A.C. contactor 30 disconnects corresponding to ac contactor coil 40, and supply-water pump 3 controls electricity
Machine dead electricity, supply-water pump 3 stop supplying water so that the water in cistern 4 stops entering feed pipe 3.When the tube wall pressure of feed pipe 22
During reduction, pressure gauge 9 monitors the change of water supply inner pipe water pressure, when the pressure value detected is less than regulation high pressure recovery value,
The high limit loop of pressure disconnects in pressure gauge 9 so that the dead electricity of the second relay coil 35 in console 10, high voltage alarm indicator lamp
Extinguish, buzzer stops making sound, and second relay contact 39 is closed corresponding to the second relay coil 35, and last supply-water pump 3 is controlled
Electric motor loop processed works on power.
Above disclosed is only specific embodiment of the present utility model, but the scope of protection of the utility model not office
