An embodiment of the present invention provides a method for controlling a rotational speed of a device, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a method for controlling a rotational speed of a device according to the present invention.
In this embodiment, the device rotation speed control method is applied to a lubrication device, where the lubrication device may include a mechanically connected oil tank and an oil pump, and the method includes:
step S10, acquiring oil temperature data of lubricating oil in the oil tank;
the lubrication device is a device with a lubrication function, and the lubrication device can lubricate in a manner of conveying lubricating oil to the device to be lubricated. The lubricating device in the embodiment has high applicability to the to-be-lubricated device with a gear reduction mechanism such as a fracturing pump. The execution body of the embodiment may be a controller in the lubrication apparatus, and in some embodiments, the controller may be replaced with an upper computer. The oil tank and the oil pump are basic components for lubrication, the oil tank stores lubricating oil, and the oil pump conveys lubrication in the oil tank to equipment to be lubricated. The oil pump can be mechanically connected with the oil pump motor, and the oil pump motor drives the oil pump to rotate. The oil temperature data characterizes the temperature of the lubricating oil.
Step S20, according to the oil temperature data and a preset temperature rotating speed mapping relation, the rotating speed data associated with the oil temperature data is searched;
the preset temperature and rotation speed mapping relation can be regarded as the relation between oil temperature data and the proper starting rotation speed of the oil pump, can be obtained through actual measurement, is stored in the lubricating equipment in advance, and is directly read under the condition that the oil pump needs to be started for lubrication. In the preset temperature and rotation speed mapping relation, rotation speed data associated with the oil temperature data can be regarded as optimal starting rotation speed data of the oil pump under the temperature of lubricating oil of the oil temperature data. Under the condition that the oil pump is started by using the rotating speed data, the problem of current overload caused by too low oil temperature and high rotating speed is avoided, and the starting performance is not influenced due to overlong starting time under the condition that the oil temperature is high.
The relationship between the temperature and viscosity of the lubricating oil is also of concern in obtaining the preset temperature-rotational speed map. FIG. 3 is a graph of temperature viscosity of lubricating oil, in FIG. 3 the abscissa indicates temperature in degrees Celsius and the ordinate indicates viscosity in mm 2 Curve 1 represents a brand a lubricant and curve 2 represents a brand B lubricant, and it can be seen from fig. 3 that the viscosity of the lubricant decreases with increasing temperature, regardless of the brand of lubricant. Therefore, under the condition of low oil temperature, the oil pump is started at a low rotating speed, so that overload of a motor is prevented, and under the condition of high oil temperature, the oil pump is started at a high rotating speed, and the lubricating requirement of the fracturing pump can be rapidly met.
In some possible embodiments, the rotational speed at the maximum torque of the oil pump motor is the 1 st rotational speed when the lubricating oil temperature is low, namely the 1 st oil temperature, and the rotational speed at the maximum torque of the motor is the 2 nd rotational speed when the lubricating oil temperature is high, namely the 2 nd oil temperature; and if the maximum torque is not reached, the 2 nd rotating speed is the maximum rotating speed of the motor. And according to the 1 st oil temperature and the 1 st rotating speed as one group of data and the 2 nd oil temperature and the 2 nd rotating speed as the other group of data, establishing a linear relation, calculating to obtain the optimal starting rotating speed under each oil temperature, and establishing a preset temperature rotating speed mapping relation by using each oil temperature and the optimal starting rotating speed. In the building process, oil pump motors with different powers can be used for testing, so that data can be obtained.
And step S30, controlling the oil pump to rotate based on the rotating speed data, pumping out the lubricating oil, and lubricating equipment to be lubricated.
The rotating speed data is obtained, the rotating speed of the oil pump can be controlled to be the same as the optimal starting rotating speed represented by the rotating speed data, the oil pump is started to operate in a proper state, the oil pump pumps out lubricating oil in the oil tank, and the lubricating oil is conveyed to equipment to be lubricated through a pipeline to be lubricated. In the actual construction process, the lubricating oil temperature is basically consistent with the ambient temperature when the fracturing pump is started, the lubricating oil temperature is lower in winter, the lubricating oil viscosity is higher, the lubricating oil temperature is higher in summer, the lubricating oil viscosity is lower, or the lubricating oil temperature is still high when the fracturing pump is stopped in the middle of construction. The rotation of the oil pump is controlled based on the rotation speed data obtained by the preset temperature and rotation speed mapping relation, so that the temperature of the environment can be adapted, and the running performance of the lubricating equipment is improved.
In this embodiment, oil temperature data of lubricating oil in the oil tank is obtained; searching rotational speed data associated with the oil temperature data according to the oil temperature data and a preset temperature rotational speed mapping relation; and controlling the oil pump to rotate based on the rotating speed data, pumping out the lubricating oil, and lubricating equipment to be lubricated. The preset temperature and rotation speed mapping relation can comprise proper starting speeds of the oil pump under different oil temperature conditions, when the equipment to be lubricated is required to be lubricated in practical application, the proper starting rotation speed can be found according to the acquired oil temperature data, the oil pump is controlled to start at the proper rotation speed, overload of a motor caused by starting at a low temperature at an excessive rotation speed can be avoided, the oil pump can be started at a high temperature at a high rotation speed, the starting requirement of the equipment to be lubricated is met in a short time, and the running performance of the equipment to be lubricated is improved.
Further, in a second embodiment of the apparatus rotational speed control method of the present invention, the method includes:
step S11, judging whether a lubrication starting instruction is received;
fig. 4 is a schematic structural diagram of a lubrication system, as shown in fig. 4, an oil tank, an oil pump and equipment to be lubricated are mechanically connected through an oil delivery pipeline, the conveying direction of lubricating oil is shown by an arrow in the figure, the oil tank can be further provided with an oil temperature sensor, a temperature detecting head of the oil temperature sensor extends into the lubricating oil in the oil tank, and the oil delivery pipeline can be further provided with an oil pressure sensor.
In the running process of the equipment to be lubricated, parts with higher friction loss of the gear reduction mechanism can be lubricated, and the service life of the parts is prolonged. The working state of the equipment to be lubricated refers to whether the equipment to be lubricated is in a running state, and under different working states, the requirements of the equipment to be lubricated for lubrication are different. The time for the lubrication equipment to lubricate the equipment to be lubricated is not particularly limited, and the equipment to be lubricated can be lubricated under the condition that the equipment to be lubricated is in different working states. The lubrication start command may be regarded as a command to start the lubrication device for lubrication.
The operating conditions of the apparatus to be lubricated may include an operating condition indicating that the apparatus to be lubricated is in operation, and a shutdown condition indicating that the apparatus to be lubricated is not in operation. In some possible embodiments, the manner of detecting the working state may be determined according to the working type of the equipment to be lubricated, for example, for equipment including a gear reduction mechanism such as a fracturing pump, the working state may be obtained by detecting the rotation speed of a gear, the working state may be determined when the rotation speed of the gear exceeds a specific value, and the shutdown state may be determined when the rotation speed of the gear does not exceed the specific value.
And step S12, if the lubrication starting instruction is received, acquiring temperature data measured by the oil temperature sensor as the oil temperature data.
And when a lubrication start instruction is received, indicating that lubrication equipment needs to be started, acquiring temperature data measured by an oil temperature sensor arranged in an oil tank as oil temperature data. If the lubrication start instruction is not received, whether the lubrication start instruction is received or not can be continuously monitored.
In some possible embodiments, the lubrication apparatus may further include a radiator fan, and after the step of acquiring the oil temperature data of the lubricating oil in the oil tank, may further include:
step S13, judging whether the oil temperature data is larger than a preset oil temperature threshold value or not;
the preset oil temperature threshold value can be regarded as a preset temperature value which is not exceeded by the lubricating oil in the process of lubricating the equipment to be lubricated. In the structure shown in fig. 4, it can be seen that the lubricating oil is recovered into the oil tank after being delivered into the equipment to be lubricated, forming a circulating oil path. When the lubricating equipment generates heat in the running state, the temperature of the lubricating oil is increased and mixed with the rest lubricating oil after being recovered into the oil tank, and whether the oil temperature in the oil way is too high can be determined through comparison between the oil temperature data and a preset oil temperature threshold value.
And S14, if the oil temperature data is larger than the preset oil temperature threshold value, starting the heat radiation fan to radiate heat.
Under the condition that the oil temperature data is larger than the preset oil temperature threshold value, the oil temperature in the oil way is at a higher level, and the heat dissipation fan can be started to conduct heat dissipation and temperature reduction. The start and stop of the radiator fan may be determined based on the oil temperature data. In one possible embodiment, the change of the oil temperature data is continuously monitored after the cooling fan is started, and the cooling fan is stopped when the oil temperature is reduced to a specific temperature value. The preset oil temperature threshold may be set to 50 ℃. Under the condition that the oil temperature data is smaller than or equal to a preset oil temperature threshold value, the oil temperature data can be continuously acquired in a certain time period, and the working state of the lubricating equipment is monitored.
In this embodiment, when the lubrication start command is received, temperature data measured by the oil temperature sensor is obtained as oil temperature data, the oil temperature data is greater than a preset oil temperature threshold value, and the heat dissipation fan is started to dissipate heat, so that the oil temperature in the oil path can be prevented from being too high, heat dissipation is performed on equipment to be lubricated, and the influence on the operation of the equipment to be lubricated due to poor heat dissipation and lubrication is avoided.
Further, in a third embodiment of the apparatus rotational speed control method of the present invention, the method includes:
step S21, determining a temperature value matched with the oil temperature data in the preset temperature and rotation speed mapping relation;
the expression forms of the preset temperature and rotation speed mapping relation can comprise a temperature and rotation speed curve or a temperature and rotation speed relation table, and in different expression forms, the temperature and the rotation speed are used as associated indexes to be combined, and the temperature and the rotation speed can be respectively used as an abscissa to establish the temperature and rotation speed curve or establish the temperature and rotation speed relation table.
Under the condition that a temperature rotating speed curve is adopted as a preset temperature rotating speed mapping relation, the temperature rotating speed curve can be approximately solved to obtain an expression taking temperature as an independent variable and rotating speed as a dependent variable, and a temperature value represented by oil temperature data can be directly used as a temperature value matched with the oil temperature data. When the temperature rotation speed relation table is used as a preset temperature rotation speed mapping relation, the temperature rotation speed relation table generally comprises a limited number of temperature values, and each temperature value corresponds to one rotation speed value. If the temperature value which is the same as the temperature value in the temperature rotation speed relation table can be directly found, the same temperature value can be used as a matched temperature value, and if the temperature value which is the same as the temperature value in the temperature rotation speed relation table cannot be found, the temperature value with the minimum absolute value of the difference value between the temperature value and the oil temperature data can be used as the matched temperature value.
And S22, taking a rotating speed value corresponding to the temperature value as the rotating speed data.
Under the condition that a temperature rotating speed curve is adopted as a preset temperature rotating speed mapping relation, the temperature value can be directly substituted into an approximate solved expression, and the rotating speed value is obtained through calculation. Under the condition that a temperature rotation speed relation table is adopted as a preset temperature rotation speed mapping relation, a rotation speed value corresponding to the temperature value can be obtained through table lookup. The rotational speed data is represented by rotational speed values.
In this embodiment, in the preset temperature and rotation speed mapping relationships of different expression forms, the oil temperature data can be used as a basis to find out related rotation speed data, and the oil pump is started at different rotation speeds under different temperature conditions, so that the running performance of the lubrication device is improved.

the preset oil pressure threshold value can be regarded as a critical value of the oil pressure in the oil passage within a normal range. Whether the oil pressure in the oil way is normal or not can be determined through judgment of the magnitude relation between the oil pressure data and the preset oil pressure threshold value.

And S80, outputting a current overload signal if the working current exceeds a preset current threshold.
The preset current threshold can be regarded as the upper current limit value of the oil pump motor in the circuit under the normal working state. Under the condition that the working current exceeds a preset current threshold value, the overload operation of the oil pump motor is indicated, a current overload signal can be output, an operator of the equipment is reminded to check the equipment in time, and the abnormality is checked. And a timer can be started when the working current is detected to exceed the preset current threshold value, the overload time is recorded, and if the overload time exceeds the preset time length, the oil pump motor is controlled to stop rotating. And under the condition that the working current does not exceed the preset current threshold value, the working current can be continuously detected, wherein the current in the circuit is normal.
In the embodiment, whether the oil pump motor is in an overload state or not is judged by detecting the working current, a current overload signal is output under the overload state to warn an operator of the equipment, and the rotation of the oil pump motor is stopped when the overload time is too long, so that the equipment is prevented from being damaged.
