Fig. 2 is the flow chart of the oil pump control method of water cooler according to an embodiment of the present invention.As shown in Fig. 2, this hair The oil pump control method of the water cooler of bright embodiment can comprise the following steps that
S1, judges whether water cooler is in shutdown status.
S2 obtains the oil temperature in the exit of the oil temperature and oil pump in fuel tank if water cooler is in shutdown status, and Obtain the oil temperature difference between the oil temperature in the exit of the oil temperature and oil pump in fuel tank.
Specifically, temperature collecting device (e.g., oil temperature sensor) can be set with the exit of oil pump in fuel tank respectively, with Obtain the temperature of the lubricating oil in fuel tank and the temperature (that is, oil temperature supplying of fuel pump outlet) of the lubricating oil at fuel pump outlet.
According to one embodiment of present invention, the oil pump control method of water cooler further include: judge the oil temperature in fuel tank Whether less than the second preset temperature threshold;If the oil temperature in fuel tank controls heating device less than the second preset temperature threshold It opens to be heated to the oil in fuel tank, until the oil temperature in fuel tank is more than or equal to the second preset temperature threshold.Wherein, second Preset temperature threshold can be demarcated according to the actual situation, for example, the value range of the second preset temperature threshold can be 30~40 ℃。
Specifically, the lubricating oil stored in fuel tank, in some cases, for example, lower or shut down in environment temperature In time longer situation, temperature may be reduced, and there are certain passes with lubricating oil viscosity for the temperature of lubricating oil System, i.e. the temperature of lubricating oil is lower, and lubricating oil viscosity is bigger, and load when oil pump is run is bigger.Therefore, when in fuel tank When the temperature of the lubricating oil of storage is less than a certain setting value, controls the heating device built in fuel tank and open, to the profit in fuel tank Lubricating oil is heated, until the temperature of the lubricating oil in fuel tank is greater than the setting value.
That is, the lubricating oil in fuel tank can be made by heating device during water cooler is shut down Temperature is maintained at certain height, to avoid because lubricating oil viscosity is larger increase oil pump operating when load, to improve The stability and reliability of water cooler operation.
Certainly, in other embodiments of the invention, insulating layer etc. can also be added by the outside in fuel tank to make oil Lubricating oil in case is maintained at certain height, but it is uncontrollable, and environment temperature is lower or downtime In longer situation, insulating layer can also fail, and will increase certain cost, while will increase the volume of water cooler. Therefore, in an embodiment of the present invention, it is preferred that the temperature of the lubricating oil in fuel tank is made to be maintained at certain by heating device Height, and water cooler operation during, which is also effective, that is to say, that no matter water cooler is in Shutdown status is in operating status, can all be controlled the temperature of the lubricating oil in fuel tank in setting value by heating device On.
Further, when water cooler is in shutdown status, due to the effect of heating device, the lubrication in fuel tank can be made The temperature of oil still maintains a higher temperature value after water cooler is shut down for a long time and (is higher than heating device setting and opens temperature Degree), and since oil pump shuts down when water cooler is shut down, oil temperature supplying can with natural cooling and refrigerant be mixed by Gradually reduce.Therefore, the oil temperature in the exit of the oil temperature and oil pump in fuel tank when water cooler is shut down, can be obtained in real time, and is obtained The oil temperature difference (that is, fuel feeding temperature difference) between the oil temperature in the exit of the oil temperature and oil pump in fuel tank is taken, and poor according to oil temperature Value and duration, judge the standing situation of lubricating oil in pipeline and lubricating component.
S3 judges whether oil temperature difference is greater than the first preset temperature threshold and the duration is greater than the first preset time.
S4 is controlled if oil temperature difference is greater than the first preset temperature threshold and the duration is greater than the first preset time Oil pump opens the second preset time.
According to one embodiment of present invention, if oil temperature difference be less than or equal to the first preset temperature threshold or it is lasting when Between be less than or equal to the first preset time, then control oil pump is in close state.
Wherein, the first preset temperature threshold, the first preset time and the second preset time can be marked according to the actual situation It is fixed, for example, the range of the first preset temperature threshold can be 5~15 DEG C, the value range of the first preset time can for 50~ 500min, the value range of the second preset time can be 1~5min.
Specifically, when oil temperature difference is larger and duration longer (the case where preventing oil temperature fluctuation), explanation The lubricating oil in pipeline and lubricating component has been mixed into more refrigerant this moment, and is adhered because temperature is lower, is unfavorable for Water cooler is again started up, therefore, at this time can control oil pump open, with using the high temperature grease in fuel tank wash away pipeline and Lubricating component, and the lubricating oil band oil return box in pipeline and lubricating component is protected to be conducive to being again started up for water cooler Card water cooler can normally start again, not only increase water cooler reliability of operation and stability, and can keep away Exempt from occur running oily phenomenon.And when oil temperature difference is smaller or oil temperature difference is larger but the duration shorter (fuel feeding of fuel pump outlet Temperature fluctuates in a short time) when, illustrate that mixed refrigerant is less in pipeline and lubricating oil, and fuel pump outlet for oil temperature The phenomenon that degree is higher, and lubricating oil is not adhered is opened without control oil pump at this time, i.e., control oil pump is in close state.
Specifically, as shown in figure 3, the oil pump control method of the water cooler of the embodiment of the present invention can comprise the following steps that
S301, water cooler are initially located in shutdown status.
S302, judges whether the oil temperature difference DELTA T0 between the oil temperature in the exit of the oil temperature and oil pump in fuel tank is greater than One preset temperature threshold A.If so, thening follow the steps S303;If not, thening follow the steps S305.
S303, judges whether the duration is greater than the first preset time t 1.If so, thening follow the steps S304;If not, Then follow the steps S305.
S304, control oil pump open the second preset time t 2.
S305, control oil pump are in close state.
In conclusion the oil pump control method of water cooler according to an embodiment of the present invention, is in water cooler and shuts down When state, the oil temperature in the exit of the oil temperature and oil pump in fuel tank is obtained, and obtains the exit of the oil temperature in fuel tank and oil pump Oil temperature between oil temperature difference, and judge whether oil temperature difference is greater than the first preset temperature threshold and duration and is greater than the One preset time, and when oil temperature difference is greater than the first preset temperature threshold and the duration is greater than the first preset time, control Oil pump opens the second preset time.Thus, it is possible to after effectivelying prevent water cooler to shut down for a long time, pipeline and compression in oil system The lubricating oil of lubricating component is adhered because of low temperature in machine, while reducing being mixed into for refrigerant in lubricating oil, is conducive to unit next time Normal starting, effectively raise unit reliability of operation and stability, and the oily phenomenon of race can be avoided the occurrence of.
