The performance of state sealing, comprehensively have detected the actual performance of hydraulic motor and hydraulic rotary joint, compensate for static tester
The defects of dynamic sealing can not be detected.
Technical field
In order to realize above-mentioned technical purpose, a kind of horizontal screw centrifuge hydraulic motor dynamic checkout unit that the present invention designs,
It is characterized in that：It includes motor, and the output shaft of the motor is connected with power transmission shaft, the first belt pulley is housed on the power transmission shaft
Group and the second belt pulley set, second belt pulley set take the left disc spins of dynamic magnetic powder cluth to, the right disk of magnetic powder cluth with it is thin
The left axle connection of type torque sensor, slim torque sensor right axle pass through transition plum blossom axle and the output shaft of tested hydraulic motor
Connection, it is tested hydraulic motor and is arranged on by bolt on universal contact, the first belt pulley set drives universal contact rotation.
Further, hydraulic power unit is connected by swivel joint with tested hydraulic motor to being tested hydraulic motor fuel feeding.
Further, first bearing seat group, the first belt pulley set are stretched out in drive shaft cartridge both ends in first bearing seat group
Both ends of the drive shaft is attached separately to the second belt pulley set.
Further, the driven pulley of second belt pulley set is in second bearing seat group.
Beneficial effect
A kind of horizontal screw centrifuge hydraulic motor dynamic checkout unit provided by the invention, unit simulation hydraulic motor and
The real working condition of hydraulic rotary joint, both have detected load capacity, have detected the performance of dynamic sealing again, comprehensively have detected liquid
The actual performance of pressure motor and hydraulic rotary joint, the defects of static tester can not detect dynamic sealing is compensate for, eliminated
Substandard products may be mixed into the hidden danger of assembly shop.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the embodiment of the present invention.
Accompanying drawing 2 is the structural representation of overlook direction of the embodiment of the present invention.
Embodiment
With reference to the accompanying drawings and examples, the present invention will be further described.
Embodiment
As shown in figure 1 and 2, a kind of horizontal screw centrifuge hydraulic motor dynamic checkout unit, it is characterised in that：It includes electricity
Machine 1, the output shaft of the motor 1 are connected with power transmission shaft 2, first belt pulley set 3 and the second belt pulley are housed on the power transmission shaft 2
Group 4, second belt pulley set 4 drive 5 left disc spins of magnetic powder cluth, 5 right disk of magnetic powder cluth and slim torque sensor 6
Left axle connection, the slim right axle of torque sensor 6 is tested by the output axis connection of transition plum blossom axle 7 and tested hydraulic motor 8
Hydraulic motor 8 is arranged on universal contact 9 by bolt, and the first belt pulley set 3 drives universal contact 9 to rotate.
Hydraulic power unit 10 is connected by swivel joint 11 with tested hydraulic motor 8 to being tested the fuel feeding of hydraulic motor 8.
The power transmission shaft 2 stretches out first bearing seat group 12, the He of the first belt pulley set 3 mounted in both ends in first bearing seat group 12
Second belt pulley set 4 is attached separately to the both ends of power transmission shaft 2.
The driven pulley 401 of second belt pulley set 4 is in second bearing seat group 13.
Carrying out horizontal screw centrifuge hydraulic motor performance test process using the present apparatus is：
The first step, according to the specification size of tested hydraulic motor, the transition plum blossom axle 7 to match therewith is selected, and passed through
Cross plum blossom axle 7 the slim right axle of torque sensor 6 is connected with the output shaft of hydraulic motor, then by tested hydraulic motor screw
On universal contact 9；
Second step, hydraulic rotary joint 11 is arranged on hydraulic motor 8；
3rd step, hydraulic rotary joint 11 and the phase inversion of hydraulic power unit 10 are connected by two oil pipes；
4th step, hydraulic power unit 10 is opened, to the fuel feeding of hydraulic motor 8, the slim right axle of torque sensor 6 starts to rotate；
5th step, drive motor 1 and be raised to rated speed, power transmission shaft 2 starts to rotate and drives the first belt pulley set 3 and second
Belt pulley set 4 rotates, and due to the effect of belt, the driven pulley 401 of the second belt pulley set 4 also begins to rotate, then magnetic powder clutched
5 left disc spins of device；Meanwhile first belt pulley set 3 drive hydraulic motor 8 shell rotation.
So far, hydraulic motor rotates at a high speed in itself, while its output shaft also drives 5 right disc spins of magnetic powder cluth so that
The left and right disk row of magnetic powder cluth 5 is into differential.If the exciting curent of magnetic powder cluth 5 is zero, the left and right disk of magnetic powder cluth 5
Between do not couple, for hydraulic motor 8 in zero load；When being gradually increased exciting curent, due to the effect of magnetic, magnetic
Coupling is produced between the left and right disk of clutch 5, the output shaft of hydraulic motor 8 starts stress.Exciting curent is bigger, and the degree of coupling is got over
Greatly, the output shaft stress of hydraulic motor 8 is bigger.Keep exciting curent constant when hydraulic motor 8 reaches rated output torque.Arrive
Untill this, hydraulic motor 8 is under real operating mode, that is, while exporting nominal load, itself is rotated equivalent to centrifugation at a high speed
Machine is operated under rated speed.Kept for enough testing times under such state, if without oil leakage phenomenon, and moment of torsion is not past
Fall, show that the hydraulic motor and swivel joint are qualified, it is otherwise unqualified.Certain above-mentioned test should be controlled by PLC, each parameter
Recorded by upper computer detection and printed.
A kind of horizontal screw centrifuge hydraulic motor dynamic checkout unit provided by the invention, unit simulation hydraulic motor and
The real working condition of hydraulic rotary joint, both have detected load capacity, have detected the performance of dynamic sealing again, comprehensively have detected liquid
The actual performance of pressure motor and hydraulic rotary joint, the defects of static tester can not detect dynamic sealing is compensate for, eliminated
Substandard products may be mixed into the hidden danger of assembly shop.
