Abstract
The utility model provides an online detection device for the volumetric efficiency of a constant-pressure variable pump, wherein a pinion pasted with an indicator is arranged on a constant-pressure variable pump shell through a pin shaft, and a marking disc is stuck on the shell behind the pinion; the big gear wheel with the pointer is arranged on an inner piston of the constant pressure variable pump through a mandrel, a dial is adhered to a shell at the front end of the pointer, and the big gear wheel is in meshing transmission with the small gear through gear teeth. When the swash plate of the constant-pressure variable pump inclines, the inner piston drives the large gear and is meshed with the small gear to rotate, the indicating signs and the pointers on the large gear and the small gear deflect, and the angle displayed by the dial of the large gear can be directly amplified to the indicating plate through the small gear, so that whether the pump meets the production requirement is judged. The online detection device is reasonable in structural design, convenient and fast in detection means, and convenient to read, and realizes online detection, so that the maintenance cost is reduced, the production operation efficiency is improved, and the labor intensity is reduced.
Description
Technical field
The utility model belongs to Measuring and testing utensil field, relates in particular to a kind of device of online detection hydraulic constant pressure variable displacement pump volumetric efficiency.
Background technique
At present; The constant pressure variable displacement pump that uses both at home and abroad all is to reflect the swash plate angle of this constant pressure variable displacement pump through being embedded in swash plate angle indicator panel on the constant-pressure variable pump case; Be that rough this pump of indication is operated in full flow output state or no flow output state, only be used for judging whether the stroking mechanism of pump is normal.Because the angular detection ratio of precision of this swash plate angle indicator panel is lower; And the pairing swash plate angle of the volumetric efficiency of pump variation (volumetric efficiency of new pump drops to acceptable volumetric efficiency minimum) is smaller, therefore is difficult to accurately understand through this indicator panel the volumetric efficiency situation of change of constant pressure variable displacement pump.
In addition; The volumetric efficiency of intrinsic constant pressure variable displacement pump detects and must carry out by off-line; Can't realize that online volumetric efficiency detects, therefore in volumetric efficiency testing process, directly influence the normal operation of producing constant pressure variable displacement pump; And labor intensity is big, also can produce additional apparatus dismounting and detection, freight.
Summary of the invention
The utility model aim to provide a kind of can online easily and efficiently detection constant-pressure variable pump volumetric efficiency, thereby increase work efficiency, minimizing expense expenditure guarantees to produce the constant-pressure variable pump volumetric efficiency on-line measuring device of normal operation.
For this reason, the solution taked of the utility model is:
A kind of constant-pressure variable pump volumetric efficiency on-line measuring device comprises constant-pressure variable pump case and inner carrier, it is characterized in that, is made up of small gear, bearing pin, indicateing arm, sign dish, gearwheel, axle, pointer and dial; Small gear is installed in through bearing pin on the housing of constant pressure variable displacement pump, and with the concentric sign dish that is stained with of small gear, the small gear front surface posts indicateing arm on the housing of small gear back; The gearwheel that the surface is stained with pointer is installed in through axle on the inner carrier of constant pressure variable displacement pump, on the constant-pressure variable pump case of pointer front end, is pasted with a dial, and gearwheel is through the gear teeth and pinion transmission.
All be printed on positive negative angle on said sign dish and the dial.
Basic principle of the utility model and effect are:
When the swash plate run-off the straight in the constant pressure variable displacement pump is that the flow of pump is when changing; The inner carrier of pump will drive gearwheel and rotate, and gearwheel pinion mate again rotates, and pointer and indicateing arm on the big small gear all will deflect; Because the structural type of big pinion gear teeth wheel set; The angle that the gearwheel dial is shown can directly be amplified on the sign dish through small gear, is convenient to accurately read the angle numerical value of deflection, thereby whether the volumetric efficiency of judging this pump satisfies the requirement of producing.Its reasonable in design, detection means is convenient and swift, and the testing result degree of accuracy is high, is convenient to read and discern, and has realized online detection fully, thereby reduce maintenance cost, improves production operation efficiency, and reduces labor intensity, and guarantees the stable operation of producing.
Description of drawings
Accompanying drawing is a constant-pressure variable pump volumetric efficiency on-line measuring device structural representation.
Among the figure: gearwheel 1, axle 2, small gear 3, bearing pin 4, indicateing arm 5, sign dish 6, pointer 7, dial 8.
Embodiment
Visible by accompanying drawing, the utility model constant-pressure variable pump volumetric efficiency on-line measuring device mainly is made up of gearwheel 1, axle 2, small gear 3, bearing pin 4, indicateing arm 5, sign dish 6, pointer 7 and 8 of dials.Small gear 3 is installed in the surface of shell of constant pressure variable displacement pump through bearing pin 4; Be stained with a sign dish 6 with small gear 3 is concentric on the housings of small gear 3 back; Indicateing arm 5 sticks on the front surface of small gear 3, and during the angle zero deflection, indicateing arm 5 arrows are just referring on 0 ° of sign dish 6.Gearwheel 1 is installed in through axle 2 on the inner carrier of constant pressure variable displacement pump, and the surface of gearwheel 1 is stained with pointer 7, on the constant-pressure variable pump case of pointer 7 front ends, is pasted with a dial 8, and during the angle zero deflection, the arrow of pointer 7 also refers on 0 ° of dial 8.Gearwheel 1 is through the gear teeth and small gear 3 engagement driving, and promptly gearwheel 1 is a driving wheel, and 3 of small gears are driven wheel, and the modulus of big small gear is confirmed according to want amplification multiple is corresponding.
