Abstract
The utility model relates to a kind of cooling-water machine water inletting monitoring device, and comprise the condenser, compressor, evaporimeter and the water pump that connect successively, also comprise the flow controller being arranged on condenser input port place, described flow controller is connected with the controller of cooling-water machine.The utility model plays a role in cooling-water machine use procedure, prevents the possibility of condenser lack of water, fundamentally solves a series of faults caused thus, saves production cost, improve the operating efficiency of machine.
Description
Technical field
The utility model relates to a kind of supervising device of water-cooled cooling water machine, particularly relates to a kind of condenser water inletting monitoring device.
Background technology
Water-cooled cooling water machine is made up of three relevant systems: coolant circulating system, water circulation system, electric-control system.Utilize evaporimeter to make refrigerant and recirculated water carry out heat exchange, refrigerant absorbs thermic load in water, rapid cooling temperature of circulating water for the production of, by compressor by carry heat to cooler, carry out heat exchange by refrigerant and cooling water, complete a circulation.
Fig. 1 and Fig. 3 is respectively operating diagram and the electric-control system schematic diagram of common cooling-water machine, and cooling-water machine has multiple protection measure at work, but appoints in actual production and so frequently occur that compressor fault comprises overtemperature, superpressure, secondary refrigerant leakage, compressor burn.NULL finds; mainly because cooling water disappearance in condenser causes refrigerant overtemperature; pressure durations increases; the trigger protection measure until overstep the extreme limit; in the process, condenser relief valve just may be caused to drain refrigerant decompression, compressor overtemperature, superpressure; increase compressor load, even burn.When above-mentioned fault occurs, cooling-water machine all has the safeguard measure such as warning, emergency shutdown, but not for the monitoring and protection measure of condenser, does not have this series products on the market.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of and improves cooling-water machine service life, security performance is high, production efficiency is high condenser monitoring and protecting device.
In order to solve above technical problem, the utility model provides a kind of cooling-water machine water inletting monitoring device, comprise the condenser, compressor, evaporimeter and the water pump that connect successively, it is characterized in that: also comprise the flow controller being arranged on condenser input port place, described flow controller is connected with the controller of cooling-water machine.
The technical scheme that the utility model limits further is:
Further, described flow controller comprises the auxiliary reclay of flow switch and series connection with it, and described flow switch and auxiliary reclay are connected to the controller of cooling-water machine.
Further, described flow switch is mechanical flow switch.
Further, the input voltage of described flow switch is 12V.
Further, the microcomputer controller of the controller of described cooling-water machine to be model be KL118.
The beneficial effects of the utility model are: the utility model plays a role in cooling-water machine production process, prevent the possibility of condenser lack of water, fundamentally solve a series of faults caused thus, save production cost, improve the operating efficiency of machine.

Detailed description of the invention
embodiment 1
A kind of cooling-water machine water inletting monitoring device that the present embodiment provides, as shown in Figure 2 and Figure 4: comprise the condenser 1, compressor 2, evaporimeter 3 and the water pump 4 that connect successively, also be provided with the auxiliary reclay of flow switch 5 and series connection with it in condenser 1 water inlet, flow switch and model are that the microcomputer controller of KL118 is connected.
Implementation step is as follows:
(1) at condenser 1 water inlet, a flow switch 5 is installed, this flow switch is mechanical flow switch, when cooling water flow is less than setting flow, trigger alarm signals GP2 also passes to microcomputer controller, for detecting the cooling water flow entering condenser.
(2) 6. flow switch signal GP2 is switching signal, get 12V voltage signal at microcomputer controller, connect with GP2 signal and auxiliary reclay KA3 coil 7 successively, when the microcomputer controller that model is KL118 receives GP2 signal, KA3 coil obtains electric work, and KA3 normally opened contact closes.
(3) as shown in Figure 4, KA3 normally opened contact 10 is in parallel with GP1 signal, when contact 10 closes; signal input microcomputer controller input port 5, cooling-water machine water-level alarm is shut down, and normally opened contact 8 is connected with alarm lamp L simultaneously; 8 closed time, 9. alarm lamp works, and is shown as lack of water fault.
(4) when condenser flow of inlet water recovers normal, 7810 automatically reset, ann reset, and cooling-water machine works on.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
