A kind of compressor of air conditioner bearing temperature protective device
Technical field
The utility model is a kind of compressor of air conditioner bearing temperature protective device, belongs to the innovative technology of operation of air conditioner protective device.
Background technology
Compressor of air conditioner is in the process of running up, because main shaft and bearing matching problem or bearing quality problem, usually occur owing to damage of bearings causes spindle deformation, the fracture of compressor of air conditioner, even the motor that compressor of air conditioner occurs phenomenon such as burns, lose very big.Therefore, if when the bearing of compressor of air conditioner has just begun to go wrong, just can remind the user to change bearing, accident potential is eliminated in bud, just the long-life is used air conditioner compressed machine equipment well.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of reasonable in design, and is easy to use, the compressor of air conditioner bearing temperature protective device that maintenance cost is low.The utility model can just stop the compressor of air conditioner operation when air conditioner compressed machine bearing has just begun to show fault, remind the user to change bearing, thereby avoids phenomenons such as compressor of air conditioner spindle deformation, fracture even motor burn to take place.The utility model control is convenient, easily operation.
The technical solution of the utility model is: compressor of air conditioner bearing temperature protective device of the present utility model; include temp probe, central controller, control device; wherein temp probe is installed on the position that can respond to the compressor of air conditioner bearing temperature; the signal output part of temp probe is connected with the signal input part of central controller; the signal output part of central controller is connected with the signal input part of control device, and the signal output part of control device is electrically connected with the control end of compressor of air conditioner input prime mover.
The signal output part of said temperature probe is connected with the signal input part of central controller by signal converter.
The said temperature probe is fixed on the bearing pedestal of compressor of air conditioner.
Above-mentioned central controller, signal converter and control device are installed together.
The utility model is owing to adopt temp probe to detect the bearing pedestal temperature with the structure that starts or stops of control compressor of air conditioner, avoid occurring air conditioner compressed machine bearing and damaged the phenomenon that also continuation start causes compressor damage, reach in advance the purpose of safeguarding, avoid bigger loss.The utility model is simple in structure, and is safe and reliable.The utility model is that a kind of design is ingenious, function admirable, convenient and practical compressor of air conditioner bearing temperature control device.

Fig. 1 is structural representation of the present utility model.
Embodiment
Structural representation of the present utility model as shown in Figure 1; compressor of air conditioner bearing temperature protective device of the present utility model; include temp probe 2, central controller 5, control device 6; wherein temp probe 2 is installed on the position that can respond to the compressor of air conditioner bearing temperature; the signal output part of temp probe 2 is connected with the signal input part of central controller 5; the signal output part of central controller 5 is connected with the signal input part of control device 6, and the signal output part of control device 6 is electrically connected with the control end of compressor of air conditioner input prime mover 7.
The signal output part of said temperature probe 2 is connected with the signal input part of central controller 5 by signal converter 4.The signal that temp probe 2 sends is passed to central controller 5 by signal converter 4, and central controller 5 provides and controls signal to control device 6, and control device 6 can be controlled the start and stop of compressor of air conditioner input prime mover 7.
In the present embodiment, said temperature probe 2 is fixed on the bearing pedestal 3 of compressor of air conditioner 1.
In the present embodiment, above-mentioned central controller 5, signal converter 4 and control device 6 are installed together.
The guard method of the utility model compressor of air conditioner bearing temperature protective device comprises the steps:
1) compressor of air conditioner input prime mover 7 starts, 1 operation of drive compression machine, under the bearing normal operating condition, bearing temperature rise is less, the temperature rise of corresponding axis bearing 3 is also less, and temp probe 2 sends normal signal and outputs to signal converter 4, is transferred to central controller 5 again, central controller 5 output normal signal are to control device 6, and control device 6 control compressor of air conditioner input prime mover 7 continue operation.
2) when bearing appearance distortion waits the irregular operating phenomenon, bearing temperature rise is higher, the temperature rise of corresponding axis bearing 3 is also higher, temp probe 2 sends fault-signal and outputs to signal converter 4, be transferred to central controller 5 again, central controller 5 is according to setting program, the output fault-signal is to control device 6, control device 6 control compressor of air conditioner input prime mover 7 are out of service, can change bearing of compressor by devices such as external touch, man-machine dialog interface, warning light, electric bell notice use and management person simultaneously.
In the present embodiment, above-mentioned control device 6 can the time of adjusting notice and stopping, avoiding occurring compressor of air conditioner long problem 1 maintenance time according to the actual conditions of user's request and protected compressor of air conditioner 1.
