Abstract
The utility model discloses a kind of antifreeze control circuits of welding equipment water-cooling system, comprising: the first branch, the first branch include pulsating pump, the start stop switch which circulate cooling water, the control pulsating pump that concatenates with pulsating pump opens, stops；The antifreeze control circuit further includes being attempted by the second branch at start stop switch both ends, and 1. by selection switch, 2. contact, time relay contact concatenate the second branch；The time relay contact is controlled by third branch, and 3., 4. contact, time relay coil concatenate for the third branch routing air-break circuit-breaker, selection switch.The time relay is the DH48S-S time relay.It is described that switch is selected to select to switch for XB2BD21C.The utility model circuit structure is simple, is not necessarily to staff on duty, can effectively prevent the bursting by freezing of cooling water pipe, save human resources, ensure safety production, improve production efficiency.
Description
Technical field
The utility model belongs to automatic control technology field, more particularly to a kind of antifreeze control electricity of welding equipment water-cooling system
Road.
Background technique
My company's processing workshop one large-scale pressure drag welding machine, the cooling water that its rectifier diode needs to recycle at work into
Row cooling, its cooling water is not recycled but still is maintained in cooling water pipe when halt production, this quiet in cooling water pipe to winter
Cooling water only easily freezes to freeze, and cooling water pipe is caused to burst, so as to cause rectifier diode damage, in order to avoid the feelings
The generation of condition, usually send special messenger 24 hours it is on duty, interruption, which opens pulsating pump, makes the circulation of cooling water discontinuity, to realize cooling
The non-icing purpose of water.But not only the time interval of waste of manpower resource but also cooling water circulation is uneven for this method, still
Freeze the hidden danger to freeze there are cooling water.
Utility model content
To solve the above problems, the utility model proposes a kind of antifreeze control electricity of welding equipment water-cooling system
Road, the circuit structure is simple, is not necessarily to staff on duty, can effectively prevent the bursting by freezing of cooling water pipe, save human resources, ensures
Safety in production, improves production efficiency.
To achieve the goals above, the utility model uses following scheme, comprising:
The first branch, the first branch include pulsating pump, which circulate cooling water；It is concatenated with pulsating pump
The start stop switch that control pulsating pump opens, stops；
The antifreeze control circuit further includes being attempted by the second branch at start stop switch both ends, and the second branch is by selecting out
It closes 1., 2. contact, time relay contact concatenate；
The time relay contact is controlled by third branch, and the third branch routing air-break circuit-breaker, selection switch
3. 4. contact, time relay coil concatenate.
The time relay is the DH48S-S time relay.
It is described that switch is selected to select to switch for XB2BD21C.
The utility model circuit structure is simple, is not necessarily to staff on duty, can effectively prevent the bursting by freezing of cooling water pipe, save people
Power resource ensures safety production, improves production efficiency.
Detailed description of the invention
Fig. 1 is the utility model electrical block diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, so that those skilled in the art can be more
Add and be apparent from, as shown in Figure 1, the utility model includes:
The first branch, the first branch include pulsating pump 1, which circulate cooling water；It is concatenated with pulsating pump
The control pulsating pump start stop switch K1 that opens, stop；
The antifreeze control circuit further includes being attempted by the second branch at start stop switch both ends, and the second branch is by selecting out
Close SA 1., 2. contact, time relay contact SJ1 are concatenated；
The time relay contact is controlled by third branch, the third branch routing air-break circuit-breaker ZK, selection switch
3., 4. contact, time relay coil SJ are concatenated SA.
The time relay is the DH48S-S time relay.
It is described that switch is selected to select to switch for XB2BD21C.
During normal production, start stop switch K1 is in closed state, selects switch SA 1., 2. contact, 3., 4. contact difference
It disconnects, the continual operation of pulsating pump makes cooling water be in continual recurrent state；When stopping production, in winter in order to prevent
The bursting by freezing of cooling water pipe disconnects start stop switch K1, makes to select switch SA 1., 2. contact, 3., and 4. contact is respectively closed, by when
Between relay be adjusted to suitable time interval, close air-break circuit-breaker ZK, at this moment pulsating pump can be according to the scheduled time
Interval carries out the work of discontinuity, to make the circulation of cooling water discontinuity, realizes the non-icing purpose of cooling water.
The utility model circuit structure is simple, is not necessarily to staff on duty, can effectively prevent the bursting by freezing of cooling water pipe, save people
Power resource ensures safety production, improves production efficiency.
