Description
Technical field
The utility model relates to plunger pump, reciprocating pump testing apparatus, also can be used for mechanical load tests such as other pump class, gear-box.
Background technique
At present, the device that is used for plunger pump, reciprocating pump test has following two kinds: a kind of is by motor, hydraulic transmission gear box, tested pump testing, manifold and the combined structure of measuring and controlling, and another kind is by low-voltage direct motor, gearbox, tested pump testing, manifold and the combined structure of measuring and controlling.First kind of device adopts motor, plays the good control of speed, can satisfy the high speed operation requirement, but the big influence of noise is to the normal faut detection of pump, and smoke-discharging pollution makes the experiment work environment poor in addition.In addition, fuel consume is big, the user cost height.Second kind of device overcome the defective that engine smoke discharging pollutes, but the noise of the low-voltage direct motor that is adopted is still excessive, and during high speed operation, rotor is polluted in the brush sparking, and machine temperature is too high to make the rate of fault increase.Use confidential configuration rectifying device of direct current drive and electric governor, the volume of low voltage motor itself is big, and the gearbox that is disposed is also big.Because the use price of low-voltage direct motor is expensive, perishable, difficulty is repaiied, troublesome maintenance, so overall cost is also high.No matter be first kind of testing apparatus or second kind of testing apparatus, owing to gear ratio is fixed, so be difficult to satisfy the test of high pulling torque, all kinds of pumps of wide rotating speed to a certain extent.
Summary of the invention
The purpose of the utility model provides that a kind of smokeless, noise are little, good energy saving property, overall cost be low, can satisfy plunger pump, the reciprocating pump testing apparatus of various speed test requirements, to adapt to the requirement of country to environmental index, energy strategy.
The utility model is the improvement of being done on the basis of existing pump testing apparatus, it is except that having speed-changing gear box, supplying the manifold and measuring and controlling of tested pump hydraulic end access, it is characterized in that adopting threephase asynchronous and liquid resistance starting speed regulator, the input of speed-changing gear box connects threephase asynchronous, output is for connecting tested pump power end, and the liquid resistance starting speed regulator inserts threephase asynchronous.
The beneficial effects of the utility model are:
1, adopt threephase asynchronous to drive, smoke-less pollution in the process of the test, noise are little, good work environment.
2, with threephase asynchronous and the assembly mutually of liquid resistance starting speed regulator, can realize the little electric current of this motor, smooth starting, full speed running, stepless time adjustment, and good energy-conserving effect.
3, the speed-changing gear box that is disposed, play the narrow limitation effect of compensation liquid resistance starting speed regulator, increase output torque in low velocity zone, enlarge speed range in high velocity, output characteristics behind the motor speed-regulating is utilized, satisfies each serial plunger pump, the test requirements document of reciprocating pump under the analog operation condition.
4, the threephase asynchronous of selecting for use is ripe, general general motor, does not have special use, maintenance requirement, stable and reliable operation, long service life; The liquid resistance starting speed regulator that adopts is energy-conservation, non-maintaining substantially, and is more more economical than using with other stepless time adjustment device (as variable-frequency governor); The speed-changing gear box that is disposed plays and increases the effect of square expansion speed, safeguards that simply the comprehensive function of these factors makes overall cost of the present utility model low.
