Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of filter detection, in particular to a sealing detection device for fuel filter of spin-on machine. BACKGROUND

[0002] The oil filter element is an oil filter, and the oil filter is used to filter out impurities, gum and water in the oil and deliver clean oil to each lubrication site.

[0003] In order to reduce the frictional resistance between the relative moving parts in the engine and reduce the wear of the parts, the oil is continuously delivered to the friction surface of each moving part to form a lubricating oil film for lubrication. The oil itself contains a certain amount of gum, impurities, water and additives. At the same time, during the operation of the engine, the entry of metal chips, the entry of impurities in the air and the generation of oil oxidation products cause the impurities in the oil to gradually increase. If the oil is not filtered, it will bring the impurities contained in the oil to the friction surface of the moving pair, accelerate the wear of the parts and reduce the service life of the engine.

[0004] The prior art has the following disadvantages: when the sealing performance of the filter is detected, the workers manually spin the filter one by one on the detection disc, and the manual spinning has low efficiency and relatively poor sealing effect. After the filter is spun on the detection disc, the filter is water sealed, and the sealing performance of the filter is detected by observing whether bubbles are generated in the water. When the detection is completed, the filter needs to be spun down one by one, and the operation process is complicated, thereby greatly reducing the detection efficiency of the filter. SUMMARY

[0005] The present application provides a sealing detection device for fuel filter of spin-on machine to solve the problems in the prior art.

[0006] The present application solves the above technical problems by the following technical means: the sealing detection device for fuel filter of spin-on machine comprises a detection pool, the top of the detection pool is open, and the bottom is sealed, a plurality of installation discs are arranged in a matrix at the bottom of the detection pool, a driving mechanism for driving the installation discs to rotate is arranged at the bottom of the installation discs, an auxiliary fixing device for fixing the filter is arranged at the top of the inner cavity of the detection pool, a water tank is arranged at the bottom of the detection pool, and a water conveying mechanism is arranged between the water tank and the detection pool; after the installation discs are rotated to drive all the filters fixed on the auxiliary fixing device to be synchronously lowered and spun on the top of the installation discs, the water conveying mechanism pumps the water in the water tank into the detection pool to continuously raise the water in the detection pool.

[0007] Preferably, the driving mechanism comprises motors arranged at the bottom of the detection tank and distributed equidistantly in transverse direction, rotating shafts connected with the detection tank in a sealing manner and arranged at the bottom of the mounting disc, and a transmission mechanism connected between the rotating shafts at corresponding positions, the output shaft end of the motor is connected with one of the rotating shafts, the rotating shafts penetrate through the detection tank and extend to the bottom of the detection tank, and the transmission mechanism is arranged at the bottom of the detection tank; the motor is operated to drive the mounting disc to rotate synchronously through the transmission mechanism.

[0008] Preferably, the transmission mechanism comprises sprockets connected with the rotating shafts outside, and chains connected between the sprockets, the rotating shafts are synchronously rotated through the sprockets and the chains.

[0009] Preferably, the auxiliary fixing device comprises movable mounting racks arranged at the top of the detection tank, and positioning openings arranged in a matrix manner at the bottom of the movable mounting racks, the middle part of the outer surface of the movable mounting racks is matched with the inner wall of the detection tank, and the positioning openings are arranged in a matching manner at the top of the filter.

[0010] Preferably, handles are connected at the top of the movable mounting racks near the edge positions, and notches are formed between the corners of the movable mounting racks and the detection tank.

[0011] Preferably, the water conveying mechanism comprises a bidirectional water pump connected with one side of the water tank, a first pipeline connected between the bidirectional water pump and the water tank, and a second pipeline connected between the bidirectional water pump and the detection tank, and the ports of the first pipeline and the second pipeline are arranged at the bottom of the water tank and the detection tank, respectively.

[0012] Preferably, a fixed cover is connected at the bottom of the detection tank, the transmission mechanism is arranged inside the fixed cover, and the motor is arranged at the bottom of the fixed cover.

[0013] The present application has the following advantages:

[0014] 1、The present application fixes the filters on the movable plate through the movable plate and the positioning openings, and then places the filters in the detection tank in an inverted manner, controls the motor to drive the mounting disc to rotate synchronously in a forward direction, and drives all the filters fixed in the positioning openings to rotate synchronously downward and be screwed on the top of the mounting disc, so that the filters can be screwed in one time, the screwing efficiency is high, the sealing effect of the filters and the mounting disc is better than that of manual screwing, and the detection efficiency of the filters can be effectively improved.

[0015] 2. Water is continuously pumped into the test tank using a two-way water pump. As the water level increases, water will overflow from the gap between the movable plate and the test tank, causing the liquid level to continue to rise. According to the liquid pressure formula P=pgh, as the liquid level increases, the pressure at the connection between the filter and the mounting plate will gradually increase. When the liquid level reaches the top of the test tank, the filter's sealing condition is observed after the water has settled. This allows for further testing of the filter's sealing performance and further ensures the filter's effectiveness.

[0016] 3. After the test is completed, control the bidirectional water pump to draw water from the test pool and pump it into the water tank for reuse. After the water in the test pool is drained, control the motor to synchronously reverse and drive the mounting plate to rotate in the opposite direction. At this time, the tested filter will move upward synchronously with the movable plate, so that the filter can be unscrewed from the mounting plate. Then, the tested filter can be removed by the handle on the movable plate. This eliminates the need to unscrew the filter one by one, which can further improve the testing efficiency.
