Embodiment 1

[0019] Such as figure 1 As shown, a grease drop point tester that can be tested continuously includes a measuring device and a cuboid oil bath box 1, and also includes an oil bath rapid temperature return device. The oil bath rapid temperature return device includes a refrigerator, a temperature return mold Group, oil bath box tray 2 and the swing arm 3 that can divide and rotate, the swing arm 3 is inline and the middle part is provided with a rotating shaft, and the rotating shaft runs through and rotates and is connected on a swing arm support platform 16, and a swing arm support platform 16 is provided below with a Swing cylinder 17, the swing angle of swing cylinder 17 is 180 °. There are two oil bath trays 2 and they are fixed on the two free ends of the swing arm 3. The oil bath 1 is placed on the oil bath tray 2, and the rotation path of the swing arm 3 has a measurement positioning point and a temperature recovery positioning point. The position of the device corresp...

Embodiment 2

[0022] The swing arm 3 is Y-shaped with a rotating shaft in the center, and there are three oil bath trays 2 fixed on the three free ends of the swing arm 3 . The angle between the three oil bath trays 2 relative to the central rotating shaft of the swing arm 3 is 120°. The swing arm 3 is driven to rotate by a stepping motor. The oil bath box 1 is cylindrical, and the oil bath box tray 2 is fixed with three oil bath box limit elastic pressure blocks, and the oil bath box space limit elastic pressure blocks are evenly distributed on a circular arc path. There are four guide rods 13. All the other are with embodiment 1.

[0023] In the present embodiment, there is one more standby oil bath tank positioning point on the rotation path of the swing arm 3, and the oil bath that has been cooled is first transferred to the standby oil bath tank positioning point with the rotation of the swing arm 3 for 120°, and the measured The oil bath is still transferred directly from the assay...

Embodiment 3

[0025] The swing arm 3 is cross-shaped and the center is provided with a rotating shaft. There are four oil bath trays 2 fixed on the four free ends of the swing arm 3. There are four oil bath tanks 1 for turnover. All the other are with embodiment 1.

Abstract

The invention discloses a lubricating grease dropping point determinator supportive of continuous determining. The lubricating grease dropping point determinator comprises a determining device and anoil bath tank and further comprises an oil bath quick temperature return device, the oil bath quick temperature return device comprises a refrigerator, a temperature return module, at least two oil bath tank trays and a rotating arm supportive of indexing rotation, the oil bath tank trays are fixedly arranged at a free end of the rotating arm, the oil bath tank is put on the oil bath tank trays, adetermining positioning point and a temperature return positioning point exist on a rotating path of the rotating arm, position of the determining device corresponds to the determining positioning point, and position of the temperature return module corresponds to the temperature return positioning point. An interval between two times of determining is greatly shortened by means of combining replacement with quick cooling temperature return, uninterrupted and continuous lubricating grease dropping point determining is realized, effective working time of instrument equipment is increased remarkably, and repeated determining efficiency is improved.

Description

technical field [0001] The invention relates to a grease measuring device, more specifically, it relates to a grease dropping point detector capable of continuous measurement. Background technique [0002] The existing lubricating grease dropping point measuring instrument needs to use an oil bath to heat the sample in sections, and it must be cooled before the next measurement after the measurement. Because the final temperature of the oil bath is very high, and the specific heat of the oil is low, it cannot naturally cool down to below the temperature required for measurement in a short period of time, and it is difficult to greatly improve the cooling effect by using ordinary heat dissipation methods such as fan blowing, and it still takes a long time. Time cooling can be used again, which seriously affects the efficiency of repeated measurement. When used as a teaching device, it is difficult to fully and comprehensively display the experimental effect due to the small e...
