Axial organ 6 ' is connected with electromotor 7 ', and torque rotary speed sensor 1 ' right-hand member is connected with being test for water pump 4 ' by shaft coupling 6 '
Connect.Electromotor 7 ' drives tested water pump 4 ', torque rotary speed sensor 1 ' to complete the measurement to rotating speed and moment of torsion.This test mode
Major defect is as follows:
(1) this test device power and test instrumentation, uses shaft coupling 6 ' to carry out between test instrumentation and tested water pump 4 '
Connecting, it is big that shaft coupling 6 ' belongs to rigid attachment noise, and vibration is big, and during startup, moment impact is big, causes electromotor 7 ' bearing to use
Service life reduction；
(2) this test device is because of its mounting structure, dismounting complexity, and big to the maintenance and repair difficulty of instrumentation, replacing is not
The program of the tested water pump 4 ' of same model size is many, adjusts to the difficulty of concentric big, is not easy to the operation of experimenter, significantly
Add the testing time, greatly reduce efficiency.
(3) this test device has unreliability, because of its mounting structure, breaks down and cannot be carried out adjusting rapidly during experiment
Whole with maintenance, and then experimentation is had a negative impact with experimental result；
(4) the connected two ends of shaft coupling 6 ', due to the existence of foozle Yu alignment error, add vibration and deformation, axle
The heart easily produces relatively skew, can cause that shaft coupling 6 ' is countershaft manufactures into bigger additional bending moment, makes the destruction that bearing is too early；Meeting
The internal stress making shaft coupling increases, and is easily broken off, and shortens the service life of shaft coupling 6 ', and even shaft flexing deformation occurs machine
Tool accident.
(5) it is unfavorable for dismounting and daily maintenance because of this test device, thus this testboard does not has accuracy the most accurately.

Simply, easy accessibility, facilitate dismounting and the test of experimenter, and the maintenance to test instrumentation, save the time with this, carry
High efficiency.
Accompanying drawing explanation
This utility model is further described the most in conjunction with the embodiments.
Fig. 1 is the structural representation of existing parallel water pump device.
Fig. 2 is the structural representation of this utility model a kind of parallel water pump device.
Detailed description of the invention
Refer to shown in Fig. 2, a kind of parallel water pump device 100, including water pump 1 and electromotor 2, also include the first belt pulley
3, the second belt pulley 4, gear 5, torque sensor unit 6, speed probe 7；Described first belt pulley 3 is the most sheathed
In the rotating shaft of electromotor 2, the second belt pulley 4 is closely sheathed on the rotating shaft of water pump 1, and the first belt pulley 3 and the second belt pulley 4
Between connected by belt；Described gear 5 is sheathed on the first belt pulley 3, and interlocks setting with the first belt pulley 3；Described turn
Speed sensor 7 is arranged corresponding to gear 5, and is connected with gear 5 sensing；Described torque sensor unit 6 includes a torque sensing
Device 61 and housing 62, described torque sensor 61 is located on housing 62, and the torsional axis (not shown) of torque sensor 61 and sending out
The rotating shaft of motivation 2 is in " one " word arrangement；For ensureing the reliable of experiment and accuracy, the torsional axis of torque sensor 61 must assure that
Rotating shaft concentric with output power.Described housing 62 has a flange 621, described flange 621 and the locking of the first belt pulley 3 even
Connect.Owing to housing 62 is less than normal compared with electromotor 2 volume, fixing connection one bearing below housing 62, to be positioned at the torsion of housing 62
Axle (not shown) also can reduce whole torque sensor 61 in an experiment because vibrations are carried with electromotor 2 rotating shaft concentric
The impact come, it is ensured that its mechanical performance.
Referring again to Fig. 2, when applying utility model works, electromotor 2 starts, and electromotor 2 is by being arranged on its axle
The first belt pulley 3 stretched couples the second belt pulley 4 being arranged on tested water pump 1, drives water pump 1 normally to work.Gear 5 leads to
The miner diameter end crossing keyway and the first belt pulley 3 closely cooperates, and the first belt pulley 3 driven gear 5 reaches synchronous rotational speed, revolution speed sensing
The detection of device 7 complete mated gear 5 rotating speed；Torque sensor 61 is coupled with the first belt pulley 3 by flange 621, completes moment of torsion
Measurement.
(1) connection of present invention belt pulley instead of traditional shaft coupling 6 ' connection, and belt pulley belongs to soft connection, noise
Low, to shake little, during startup, the impact to electromotor 2 is little, and the service life of electromotor 2 bearing can extend；
(2) present configuration is simple, easy to operate, and the installation of the tested water pump 1 of different model size is without again by difference
The cushion block of height adjusts axle center height, can be directly mounted on pedestal, and structure is more stable, dismounts convenient；
(3) present invention uses the torque sensor 61 of single flange 621, facilitates the installation of torque sensor 61 and fixes, single
Installing and using of the more convenient scene of design of flange 621, is also beneficial to the maintenance to torque sensor 61, occurs in experimentation
Fault also is able to adjust rapidly, it is not necessary to dismantle in a large number, and convenient experiment is smoothed out the collection with data；
(4) present invention uses the speed probe 7 of measure speed gears 5 formula, easy accessibility, and simple in construction is highly sensitive, the life-span
Long, trigger distance remote, there is good impact resistance and shock resistance；
(5) this testboard bay framework is simple, and each several part couples simple and reliable, and easy accessibility has greatly saved operator
