The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

As shown in fig. 1 and 2, the oil control system of the oil injection screw compression main engine of the present embodiment includes: the system comprises an air inlet device 105, a compressor host 106, an oil cylinder 107, a pipeline 110, a cooling device 103, a main controller 101, a thermosensitive control device 104 and a collecting device 102; the duct 110 includes: oil line 1102, gas line 1103, and mixing line 1101; the acquisition device 102 includes: a first temperature sensor 1021, a humidity sensor 1022, a pressure sensor 1023, and a second temperature sensor 1024. The first temperature sensor 1021, the humidity sensor 1022, the pressure sensor 1023, the second temperature sensor 1024, the cooling device 103 and the heat-sensitive control device 104 are all connected with the master controller 101; the air inlet device 105 is connected with the compressor main body 106; an exhaust port of the compressor main unit 106 is connected with the oil cylinder 107 through a mixing pipeline 1101; the oil cylinder 107 is connected with the cooling device 103 through an oil pipe 1102; the oil gas cylinder 107 outputs compressed gas through a gas pipe 1103; the cooling device 103 is connected with the compressor main machine 106 through an oil pipe 1102; the thermal control device 104 is arranged on an oil pipe 1102 between the cooling device 103 and the compressor main body 106.

The main controller 101 determines the exhaust pressure dew point temperature according to the current environment temperature, the current environment humidity and the current exhaust pressure, and the specific determination process of the main controller 101 on the exhaust pressure dew point temperature belongs to the prior art. For example, the determination process may be that the master controller 101 stores a data address table, where the data address table is a pressure dew point temperature corresponding to each of different exhaust pressure, ambient temperature, and ambient humidity. After the main controller 101 obtains the current ambient temperature, the current ambient humidity and the current exhaust pressure, the current ambient temperature, the current ambient humidity and the current exhaust pressure are compared with the stored data address table, and therefore the exhaust pressure dew point temperature matched with the current ambient temperature, the current ambient humidity and the current exhaust pressure is obtained. The discharge temperature of the compressor main unit 106 needs to be equal to or higher than the discharge pressure dew point temperature.
The main controller 101 sends the determined exhaust pressure dew point temperature and the obtained current exhaust temperature of the compressor host 106 to the cooling device 103, and the cooling device 103 cools the lubricating oil according to the exhaust pressure dew point temperature and the current exhaust temperature, for example, if the current exhaust temperature is too high compared with the exhaust pressure dew point temperature, the cooling degree needs to be increased; if the current exhaust temperature is too low compared to the exhaust pressure dew point temperature, the degree of cooling needs to be reduced.
The main controller 101 sends the exhaust pressure dew point temperature to the thermal sensitive control device 104, and the thermal sensitive control device 104 can sense the exhaust temperature at the exhaust port of the compressor main machine 106 to obtain the current sensed temperature. The thermal control device 104 adjusts the current oil passing area of the oil pipe 1102 for conveying the cooled lubricating oil to the compressor main machine 106 by the cooling device 103 according to the exhaust pressure dew point temperature and the current sensing temperature. For example, if the current sensing temperature is higher than the exhaust pressure dew point temperature, the current oil passing area of the oil pipe 1102 is increased, so that the oil injection amount to the compressor main engine 106 is increased, and the exhaust temperature of the exhaust port of the compressor main engine 106 is reduced; if the current sensing temperature is lower than the exhaust pressure dew point temperature, the current oil passing area of the oil pipe 1102 is reduced, so that the oil injection amount to the compressor main unit 106 is reduced, and the exhaust temperature of the exhaust port of the compressor main unit 106 is increased.
The air inlet device 105 conveys air to the compressor main machine 106, the oil cylinder 107 conveys the stored lubricating oil to the cooling device 104 through the oil pipe 1102, the cooling device 104 cools the lubricating oil according to the exhaust pressure dew-point temperature and the current exhaust temperature, the cooled lubricating oil is conveyed to the compressor main machine 106 through the oil pipe 1102 according to the current oil through area adjusted by the thermosensitive control device 104, the compressor main machine 106 compresses the air conveyed by the air inlet device 105 and the lubricating oil conveyed by the oil pipe 1102 to obtain an oil-gas mixture, and the oil-gas mixture is conveyed to the oil cylinder 107 through the mixing pipeline 1101. In the embodiment, the oil injection quantity and the oil injection temperature of the main compressor 106 are adjusted in real time according to the exhaust pressure dew point temperature determined by the main controller 101, when the exhaust temperature of the exhaust port of the main compressor 106 is higher than the exhaust pressure dew point temperature, the oil injection quantity is increased to reduce the exhaust temperature, and when the exhaust temperature is lower than the exhaust pressure dew point temperature, the oil injection quantity is reduced to raise the exhaust temperature, so that the exhaust temperature floats up and down at the exhaust pressure dew point temperature, the condition that the exhaust temperature is too high or too low is avoided, the effect of lubricating oil during auxiliary air compression can be ensured, and the abrasion of parts is reduced; and the generation of carbon deposition can be reduced, and the channel resistance is reduced, so that the power consumption is reduced.
Further, the oil control system of the oil injection screw compression main engine of the embodiment further includes an oil filter 108, and the oil filter 108 is disposed on the oil pipe 1102 between the cooling device 104 and the temperature-sensitive control device 104 and is used for filtering lubricating oil in the oil pipe 1102. If the lubricating system leaks and is not tightly sealed, the oil is in thermal load for a long time, and the oil is stored in an open mode, moisture and gas in the air can permeate into the oil, so that the lubricating oil contains water and gas, particle dust in the air enters or system abrasion dust falls off, and part of the oil is cracked, deteriorated and separated out into colloidal substances when the lubricating oil works at high temperature and under water for a long time. Therefore, the lubricating oil needs to be filtered to prevent the lubricating oil from containing water, gas and impurities, and corroding equipment such as the oil pipe 1102 and the compressor main unit 106.
Further, in the oil control system of the oil injection screw compression main engine according to the embodiment, the thermal control device 104 includes a thermistor 1041 and a blocking device 1042, a resistance value of the thermistor 1041 changes according to a change of a current sensing temperature, and can sense the current sensing temperature, and transmit a corresponding current sensing temperature signal to the main controller 101, so that the main controller 101 controls an opening degree of the blocking device 1042 according to the current sensing temperature, thereby controlling a current oil passing area of the oil pipe 1102. Fig. 3 is a schematic diagram of the thermal sensitive control device in fig. 1 controlling the current oil passing area of the oil pipe, as shown in fig. 3, the hatched portion indicates the current oil passing area of the oil pipe 1102, the opening degree of the isolator 1042 can be preferably divided into 5, and the current oil passing areas of the 5 oil pipes 1102 corresponding to the 5 opening degrees are respectively shown in fig. 3 as (i), (ii), (iv), for example, when the current sensing temperature sensed by the thermistor 1041 is 30 ℃, the current oil passing area of the oil pipe 1102 corresponding to the opening degree of the isolator 1042 is i, (ii) when the current sensing temperature sensed by the thermistor 1041 is 40 ℃, the current oil passing area of the oil pipe 1102 corresponding to the opening degree of the isolator 1042 is (iii), when the current sensing temperature sensed by the thermistor 1041 is 50 ℃, the current oil passing area of the oil pipe 1102 corresponding to the opening degree of the isolator 1042 is (iii), the current oil passing area of the oil pipe 1102 corresponding to the opening degree of the blocking device 1042 is a fourth value, and when the current sensing temperature sensed by the thermistor 1041 is 70 ℃, the current oil passing area of the oil pipe 1102 corresponding to the opening degree of the blocking device 1042 is a fifth value. Like this, current induction temperature is higher, the opening degree of separation ware 1042 is bigger, the current oil passing area of corresponding oil pipe 1102 is bigger, the fuel injection quantity is also bigger, after the fuel injection quantity increases, exhaust temperature can reduce, then current induction temperature that thermistor 1041 sensed also can reduce, the opening degree of separation ware 1042 diminishes, the current oil passing area of corresponding oil pipe 1102 diminishes, the fuel injection quantity also diminishes, after the fuel injection quantity diminishes, exhaust temperature risees, then current induction temperature that thermistor 1041 sensed also can risees, thereby realize dynamic cycle. In this embodiment, the opening degree of the blocking device 1042 may be set according to the exhaust pressure dew point temperature, for example, the opening degree of the blocking device 1042 corresponding to the exhaust pressure dew point temperature is a medium opening degree, so that when the current sensing temperature is lower than the exhaust pressure dew point temperature, the opening degree of the blocking device 1042 may be adjusted to a small opening degree, and when the current sensing temperature is higher than the exhaust pressure dew point temperature, the opening degree of the blocking device 1042 may be adjusted to a large opening degree, so as to ensure that the exhaust temperature of the compressor host 106 is kept at the exhaust pressure dew point temperature, and is neither too high nor too low. The blocking device 1042 may be a solenoid valve. In this embodiment, the number of the opening degrees of the blocking devices 1042 is not limited, and those skilled in the art can set the opening degrees according to specific situations. In this embodiment, a person skilled in the art can connect the master controller 101, the thermistor 1041 and the blocker 1042 according to the prior art, and details are not described here.
