DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] like Figure 1 As shown, an oil monitoring and diagnostic filtering device comprises an oil inlet (11), an oil inlet electric control valve (101), a monitoring and diagnostic module (1), a filtering module (3), an oil outlet electric control valve (102), an oil outlet (12), a data module (5) and a power module (6); when in use, the oil inlet (11) and the oil outlet (12) are connected to the oil tank of the device under test to ensure that the oil monitoring and diagnostic device can absorb oil when working. Preferably, the oil inlet (11) is located in the middle and lower part of the oil in the oil tank of the device under test; there is no special requirement for the position of the oil outlet (12) in the oil tank. In order to avoid damage to the oil monitoring and diagnostic filtering device due to excessive oil pressure, it is not recommended to connect the oil inlet (11) and the oil outlet (12) to the working oil circuit of the device under test.
[0016] The monitoring and diagnosis module (1) and the filtering module (3) are connected in parallel between the oil inlet electric control valve (101) and the oil outlet electric control valve (102) via an oil pipe; through the parallel setting, when a user selects to filter the oil or when the oil parameter data of the tested equipment does not meet the standard, the monitoring and diagnosis module (1) and the filtering module (3) can work independently or together.
[0017] The monitoring and diagnosis module (1) comprises: an oil pretreatment module (2) and an oil data acquisition module (4); the oil pretreatment module (2) is arranged before the oil data acquisition module (4) and is connected via an oil pipe; the oil is pretreated, that is, the oil of the tested equipment is pretreated by defoaming, heating and cooling before entering each sensor. The defoaming, heating and cooling measures can meet the data acquisition requirements of the sensor and improve the accuracy of the monitoring data.
[0018] like Figure 2As shown, the oil pretreatment module (2) comprises: an oil pretreatment electric control valve (202), a tank body (28), a temperature sensor (26), a pressure sensor (27), a liquid level sensor (23), a refrigeration device (25), a heating device (24), an air pump (21), an air path reversing device (22), an oil pretreatment tank oil inlet (201) and an oil pretreatment tank oil outlet (203); the temperature sensor (26), the pressure sensor (27), the The liquid level sensor (23) and the heating device (24) are arranged inside the tank body (28); the refrigeration device (25) is arranged at the bottom of the tank body (28); the air inlet pipe and the exhaust pipe of the air pump (21) are connected to the air path reversing device (22); the top of the tank body (28) is provided with a hole and is connected to the air path reversing device (22) through an air pipe; the oil pretreatment electric control valve (202) is connected to the oil inlet (201) of the oil pretreatment tank. When the device is working, the air path conversion of the air path reversing device (22) allows the air pump (21) to be used as both a vacuum pump and a delivery pump, thereby reducing the number of devices, reducing the weight of the device, and improving portability. When it is necessary to obtain particle data of pollutants in the oil, in order to avoid bubbles in the oil affecting the accuracy of particle counting, it is necessary to first switch through the gas path reversing device (22) so that the air pump (21) extracts gas in the tank (28) and the oil enters the tank (28). The air pump (21) continues to work, so that the tank (28) can maintain negative pressure, so that the tiny bubbles in the measured oil overflow, thereby improving the accuracy of particle counting. By setting the liquid level sensor (23), the liquid position of the tank 28 can be obtained. When the liquid reaches the required amount, the oil pretreatment electric control valve (202) is closed. At the same time, the amount of delivered oil can be obtained through the change of the oil level of the liquid level sensor (23), so that the monitoring data is more accurate. By setting the refrigeration device (25), the heating device (24) and the temperature sensor (26), the measured oil in the tank (28) can be kept within the temperature range specified by the national standard, such as 40°C required for viscosity measurement, thereby avoiding the measured oil temperature affecting the viscosity monitoring value.

When the oil data monitored by the oil data acquisition module (4) is qualified or the user actively closes it, the delivery pump (31), the oil inlet electric control valve (101), the oil outlet electric control valve (102) and the filtering module electric control valve (301) are closed to complete the filtering procedure.
[0021] The data module (5) is connected to the oil pre-processing module (2), the oil data acquisition module (4), the filtering module (3), the oil inlet electric control valve (101) and the oil outlet electric control valve (102) by a signal bus.
