The lipid detection device of the embodiment of the utility model can comprise the following steps when in use:

a1: a first set amount of sealing grease 101 is placed in the inner hole of the cylindrical portion 11, and a leveling plate 15 is placed above the sealing grease 101 after the upper surface of the sealing grease 101 is leveled. Specifically, as shown in fig. 1, the steel screen 13, the seal block, and the first plate 12 may be first firmly fixed to the cylinder 11 with screws. Then, 100g (first set amount) of sealing grease 101 may be put into the cylindrical portion 11, the upper surface of the sealing grease 101 may be smoothed by a manual process, and after the upper surface of the sealing grease 101 is smoothed by the manual process, the flattening plate 15 may be placed on the upper side of the sealing grease 101. Finally, the container 1 can be fixed in a corresponding position on the frame 5 by means of a locating pin.

A2: a second set amount of test fluid 102 is injected above the leveling plate 15. For example, the detection fluid 102 may be water, and 100ml (second set amount) of water may be injected into the tube 11 after the container 1 is fixed, and the container 1 may be allowed to stand for a while after the injection, thereby being stabilized.

A3: the actuator 3 is activated to apply a set pressure to the test fluid 102 and the sealing grease 101 in the container 1 through the piston 2 for a set period of time. For example, the parameters of the driver 3 may be set and adjusted in advance by the display assembly 6 according to the test requirement, and then the driver 3 may be controlled to act according to the set parameters, at this time, the driver 3 may drive the piston 2 to move down and can apply a set pressure to the detection fluid 102, where the set pressure may last for a period of time (set duration).

A4: the first plate portion 12 is monitored for water leakage over a set period of time, and the sealing grease 101 precipitated from the container 1 is weighed by the weighing assembly 4 to evaluate the water-resistant tightness of the sealing grease 101. Specifically, in the above-described process of applying the set pressure, it is possible to test whether or not there is water leakage in the lower first plate portion 12, and the leakage amount of the sealing grease 101 precipitated in the test stage is recorded by an electronic balance (weighing module 4), and the measured data can be used to evaluate the water-resistant sealing property of the grease. For example, if water leakage occurs or the leakage amount of the sealing grease 101 is larger, it means that the water-resistant sealing property of the sealing grease 101 is poor, whereas if the water-resistant sealing property is satisfactory.

A5: after the detection is completed, the drain valve 21 is opened, and then the actuator 3 is activated and the piston 2 is moved out of the container 1. Specifically, after the test, the bleed valve 21 provided in the piston 2 needs to be opened first before the piston 2 is pulled out of the cylinder 11, and thus damage to equipment and parts caused by the process of pulling out the piston 2 can be avoided. Note that the drain valve 21 is always in a closed state during the test.

The lipid detection device according to another embodiment of the present utility model may further comprise the steps of:

b1: a predetermined amount of sealing grease 101 is placed in the inner hole of the tube 11. For example, before the experiment, the deflector block 17 and the second seal cover may be fixed to the cylindrical portion 11 with screws, and then 250g (set amount) of the seal grease 101 may be placed in the inner hole of the cylindrical portion 11.

B2: the actuator 3 is activated to apply a set pressure to the sealing grease 101 in the container 1 through the piston 2 and for a set period of time. For example, the parameters of the driver 3 may be set and adjusted in advance by the display unit 6 according to the test requirement, and then the driver 3 may be operated according to the set parameters, at this time, the driver 3 drives the piston 2 to move down and can apply a set pressure to the detection fluid 102, where the set pressure may be a constant pressure, and the set pressure needs to last for a prescribed time (a set duration).

B3: the sealing grease 101 precipitated from the container 1 was weighed by the weighing assembly 4 to evaluate the pumpability of the sealing grease 101. For example, the leakage amount of the sealing grease 101 precipitated during the test phase may be recorded by an electronic balance (weighing assembly 4), and the measured data may be used to evaluate pumpability. For example, the leakage amount of the sealing grease 101 precipitated during the test phase is recorded by an electronic balance (weighing module 4), and the measured data can be used to evaluate the water-resistant sealing property of the grease. For example, the pumpability may be such that the sealing grease 101 smoothly passes through the pipe, and has a small resistance, no clogging, or the like. If the leakage amount is large, the pumpability is good, whereas if the leakage amount is large, the pumpability of the sealing grease 101 is poor.

B4: after the detection is completed, the drain valve 21 is opened, and then the actuator 3 is activated and the piston 2 is moved out of the container 1. Specifically, after the test, the bleed valve 21 provided in the piston 2 needs to be opened first before the piston 2 is pulled out of the cylinder 11, and thus damage to equipment and parts caused by the process of pulling out the piston 2 can be avoided. Note that the drain valve 21 is always in a closed state during the test.
