Embodiment 1

[0053] Embodiment 1: A water seal friction torque detector, see figure 2 , including a support frame 1, a support platform 2, a torque sensor 3, a water seal mounting seat 4, a vertical shaft 5, a fixed beam 6 and a movable beam 7, a servo motor 8, a pressure sensor 9, a lifting device 10 and a console 11; The middle part of the support frame 1 is fixedly equipped with a horizontally distributed support platform 2, and a vertically distributed torque sensor 3 is installed above the central part of the support platform 2. The upper end of the torque sensor 3 is a torque input shaft end. The upper end of the torque sensor 3 is fixedly installed with a horizontally distributed water seal mounting seat 4;

[0054] A pair of vertical shafts 5 are mounted symmetrically on both sides of the support platform 2, and horizontally distributed fixed crossbeams 6 are fixedly mounted on the tops of the two vertical shafts 5, and the two ends of the fixed crossbeams 6 are fixed on two The ...

Embodiment 2

[0074] Embodiment 2: The difference from Embodiment 1 is that the lifting device 10 is a manual screw lift.

Embodiment 3

[0075] Embodiment three: the difference from embodiment one is: as Figure 5 As shown, the motor output shaft 81 is connected with a shaft coupling 82 and a driven shaft 83, and the shaft coupling 82 is a flexible shaft coupling; through this structure, the servo motor 8 can be better protected to prevent the servo motor from 8 Overload operation, and the detection of different types of water seals can be realized by changing the size and model of the coupling 82 and the driven shaft 83.

Abstract

The invention discloses a water seal friction torque detection machine. The water seal friction torque detection machine comprises a support frame, a torque sensor, a servo motor, a pressure sensor, alifting device and a console; a support platform is mounted on the support frame; the torque sensor and a water seal mounting seat are mounted above the middle part of the support platform in sequence; vertical shaft levers are symmetrically mounted on two sides of the support platform; a fixed cross beam is mounted at the top ends of the vertical shaft levers; a movable cross beam is mounted atthe middle parts of the vertical shaft levers; the vertical servo motor is fixedly mounted at the middle part of the movable cross beam; a motor output shaft of the servo motor is aligned with the middle part of the water seal mounting seat; the movable cross beam is connected with the pressure sensor and the lifting device in sequence through a force transmission seat; the lifting device is fixedon the fixed cross beam; and the console is in data connection with the torque sensor, the servo motor, the pressure sensor and the lifting device. The water seal friction torque detection machine can be used for detecting friction torque of water seals under parameters such as different pressures and different rotation speeds, so as to provide data for design and verification of the water seals.

Description

technical field [0001] The invention relates to the field of mechanical seals of automobile cooling systems, in particular to a water pump water seal friction torque detection device. Background technique [0002] The water pump water seal is a device for preventing fluid leakage composed of at least one pair of end faces perpendicular to the axis of rotation, under the action of fluid pressure and the elastic force of the compensation mechanism, and the cooperation of auxiliary seals to keep fit and slide relative to each other. The main components of the existing water pump water seal include a rotating ring and a stationary ring, that is, the water pump water seal mainly prevents fluid leakage through the sliding working surface where the rotating ring and the stationary ring are attached and relatively slide. The specific structure of the existing water pump water seal can refer to figure 1 As shown, it includes a rotating ring assembly and a stationary ring assembly. T...
