Summary of the invention
For overcoming the defect problem existed in above-mentioned prior art, the utility model provides a kind of condensing pressure and the constant water-cooled cooling water machine of evaporating pressure, and the machine performance of this cooling-water machine is good, longer service life.
For achieving the above object, the technical scheme that the utility model adopts is:
Constant evaporation and condensing pressure water-cooled cooling water machine, mainly by refrigeration system and freezing water circuit system two large divisions, formed, wherein refrigeration system forms a closed circuit by compressor, condenser, electric expansion valve and evaporimeter successively, freezing water circuit system successively by water tank, water pump and mould successively by forming a closed circuit, the closed circuit of freezing water circuit system is through evaporimeter, the cooling water inlet place of condenser is provided with supplying temperature-adjusting water valve, and the exit of evaporimeter is provided with evaporator pressure regulator.
As a kind of preferred structure of the present utility model, evaporator pressure regulator is arranged on the muffler of evaporimeter and compressor.
Evaporator pressure regulator is for adjusting according to the variation of load the adjuster of its open degree size.Supplying temperature-adjusting water valve is to adjust according to the variation of cooling water leaving water temperature the control valve of the size of valve opening degree.
Compare with conventional art, the utility model has the advantage of:
The supplying temperature-adjusting water valve that is arranged at the condenser cooling water porch can be adjusted according to the variation of cooling water leaving water temperature the size of valve open degree, thereby control the heat exchange amount of condenser, make condensing pressure constant, equally, the evaporator pressure regulator that is arranged on the evaporator outlet place can be adjusted according to the variation of load the size of its open degree, flow-control and the load of cold-producing medium are complementary, thereby make the evaporating pressure of machine constant, be that condenser and evaporimeter can move reposefully, and not changed by cooling water temperature and the impact of load variations, thereby machine performance improves, extended the service life of machine, saved resource.
The accompanying drawing explanation:
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, constant evaporation and condensing pressure water-cooled cooling water machine mainly are comprised of refrigeration system 2 and freezing water circuit system 3 two large divisions, refrigeration system 2 is successively by evaporimeter 26, compressor 21, condenser 22, device for drying and filtering 24 and electric expansion valve 25 form closed circuit, the place, cooling water inlet of condenser 22 is provided with a supplying temperature-adjusting water valve 23, be provided with muffler between evaporimeter 26 and compressor 21, muffler is provided with evaporator pressure regulator 27, evaporator pressure regulator 27 is for adjusting according to the variation of load the adjuster of its open degree size, supplying temperature-adjusting water valve 23 is to adjust according to the variation of cooling water leaving water temperature the control valve of the size of valve opening degree, freezing water circuit system 3 mainly is comprised of water tank 31, water pump 32 and tube connector, one end of water tank 31 is connected with water pump 32, water pump 32 is connected with die entrance, and the tube connector that the outlet of mould and water tank are 31 passes through evaporimeter 26, thereby forms the closed circuit of freezing water circuit system.
The course of work of refrigeration system 2 is: the gas that becomes HTHP after compressed machine 21 compressions of the refrigerant gas of low-temp low-pressure enters condenser 22, form the high pressure liquid refrigerant of normal temperature after the water cooling that is cooled in condenser 22, after device for drying and filtering 24 dry filters deacidification, again by becoming the gas-liquid two-phase mix refrigerant of low-temp low-pressure after electric expansion valve 25 reducing pressure by regulating flows, become the low-temp low-pressure gas refrigerant the chilled water generation heat exchange that enters again afterwards evaporimeter 26 and return from freezing water circuit system 3, the low-temp low-pressure gas refrigerant is got back to compressor 21 and is so circulated after evaporator pressure regulator 27.In this process, when condenser 22 cooling water outlet temperatures change, the supplying temperature-adjusting water valve 23 at the place, cooling water inlet of condenser 22 can be adjusted according to the variation of cooling water leaving water temperature the size of valve opening degree, thereby control the heat exchange amount of condenser 22 so that condensing pressure is constant, thereby condenser 22 is able to even running; And when the load of machine changes, evaporator pressure regulator 27 on muffler can be adjusted according to the variation of load the size of open degree, the flow of cold-producing medium is controlled, with load, be complementary, thereby by the evaporating pressure constant control of machine in a setting range, thereby make machine be able to even running, machine performance improves, extend the service life of machine, saved resource.
The course of work of chilled water system 3 is: the chilled water that mould is returned enters water tank 31 after evaporimeter 26 and cold-producing medium generation heat exchange are cooled, from water tank 31, chilled water out enters mould after water pump 32 pressurizations, enter evaporimeter 26 after being heated with load generation heat exchange in mould, so circulation.
