Description
Technical field
Handpiece Water Chilling Units field is the utility model is related to, more particularly, to a kind of cooling water temperature control system.
Background technology
The compressor of water cooled chiller supplies, oil return system, is to utilize train condenser and evaporator or compressor air suction
Mouthful pressure differential, realize fuel feeding and oil return.And in spring and autumn transition season or night summer, cause machine because environment temperature is relatively low
Group high pressure it is relatively low so that unit height pressure difference is relatively low, thereby result in compressor supply, oil return it is not smooth, unit start after frequently occur
Losing oily alarm failure causes to shut down.Add that compressor is stuck, burning fault probability, and had a strong impact on compressor uses the longevity
Life, while the cooling safety of air-conditioning system is influenceed, a large amount of manpowers and material resources are consumed, cause the waste of the energy and resource.
Transition season start at present is typically that operating personnel adjust cooling water valve and the cold tower of switch to adjust cooling manually
Coolant-temperature gage, company's related personnel's workload is not only increased, and it is not in time or inaccurate so as to be caused to machine adjustment to be present
Unnecessary harm, it also result in the waste of the energy and resource.
Utility model content：
To overcome above mentioned problem, the utility model provides a kind of cooling water temperature control system, including train condenser, cold
But water pump, YE, controller, electric proportional-regulation valve and temperature sensor；The electric proportional-regulation valve is arranged on
Electronic proportion adjustment two-way or triple valve are provided with cooling water outlet pipe or on cooling water inlet pipe and bypass pipe；
The temperature sensor is located on cooling water outlet pipe；
The electric proportional-regulation valve is provided with YE；
The YE is connected with controller.
The controller is DDC controllers.
The cooling water pump is arranged on cooling water inlet or outlet pipe.
The advantages of the utility model：
The purpose of above-mentioned transformation is：Improve related operations staff's operating efficiency, avoid because adjust not in time or it is inaccurate and
Unnecessary harm is caused to machine, reduces the consumption of the energy and resource.
Brief description of the drawings：
Fig. 1 is the schematic diagram one of cooling water temperature control system provided by the utility model；
Fig. 2 is the schematic diagram two of cooling water temperature control system provided by the utility model；
Wherein 1 train condenser, 2 cooling water pumps, 3 YEs, 4 controllers, 5 electronic proportion adjustment (two-way or three
It is logical) valve, 6 temperature sensors, 7 cooling water inlet pipes, 8 cooling water outlet pipes.
Embodiment
Embodiment 1
For this item purpose concrete condition, we install electric control valve additional in cooling water pipeline, or cooling water water inlet with
A bypass regulator valve is added between water outlet to solve：Principle is water-carrying capacity of the regulation into train condenser, is produced using unit
Heat quickly improve cooling water temperature, and the water temperature substantially constant is kept, so that handpiece Water Chilling Units cooling water temperature is maintained at
Declared working condition value.
Specific embodiment is as follows：
Cooling water temperature control system includes train condenser, cooling water pump, YE, controller, electronic ratio
Regulating valve and temperature sensor；
Scheme one：Electric proportional-regulation valve is installed on cooling water outlet pipeline, passes through the TEMP of U.S.'s Johnson controls
The collaborative work of the series of products such as device, controller, YE, electric proportional-regulation valve, PID scale operations are carried out, automatically
The aperture of electric control valve is adjusted, ensures the cooling water temperature (i.e. the condensation temperature and pressure of condenser) needed for unit operation,
So as to ensure the confession of compressor in unit running process, oil return.
1st, when condenser water temperature is less than 35-37 DEG C, the electric control valve on cooling water outlet pipeline gradually turns down, and according to
PID proportion adjustment valve apertures, make condenser temperature be maintained between 35-37 DEG C；
2nd, when condenser temperature is higher than 37 DEG C, valve is opened completely.
The advantages of this programme is that rebuilding construction is simple, positive effect；Shortcoming is to need to set minimum discharge, to avoid unit
Generation water shortage alarm machine halt trouble.
Scheme two：Increase bypass pipe between cooling water inlet tube and outlet tube, electronic proportion adjustment two-way is installed on bypass pipe
(or threeway) valve, it is by the temperature sensor of U.S.'s Johnson controls, controller, YE, electric proportional-regulation valve etc.
The collaborative work of row product, PID scale operations are carried out, automatically adjust the aperture of electric control valve, ensured needed for unit operation
Cooling water temperature (i.e. the condensation temperature and pressure of condenser), so as to ensure the confession of compressor in unit running process, oil return.
1st, when condenser temperature is less than 35-37 DEG C, the motor-driven valve on bypass pipe is opened, and according to PID ratio adjusting valves
Door aperture, makes water temperature be maintained between 35-37 DEG C；
2nd, when water temperature is higher than 37 DEG C, valve is closed on bypass pipe.
The advantages of this programme is that control is accurate, and water shortage alarm machine halt trouble will not occur for unit；Shortcoming is that pipeline need to be entered
Row retrofit work amount is relatively more, it is possible to can be limited and can not construct by the existing layout of beam line in scene.
Capital equipment needed for transformation：
