Description
Technical field
The utility model is related to compression set technical field, in particular to a kind of pump housing and compressor.
Background technology
Existing compressor start is there may be the big situation of compressor pump transient drag, such as there are no reach balance
Thermal starting during pressure, oil viscosity causes greatly frictional resistance big under low-temperature condition, the big feelings of resistance caused by other reasons of the pump housing
Condition etc..But electric motor starting ability is constant, and generally 1.0-1.3 times of healthy compressor pump housing resistance, substantially satisfaction are pressed
The startup of contracting machine.But for small part situation, low temperature caused by weather reason, frequent starting causes exception of compressor etc., can
It can influence whether the startup of compressor, it is abnormal to start the service life for even influencing compressor so as to influence the satisfaction of client.
For existing scheme compressor to improve startup ability, the capability of overload for designing motor is stronger, but influences compressor
Efficiency reduces, and so as to increase the power consumption of compressor, efficiency is caused not have competitive advantage.
Existing compressor drum component is assembled up by way of hot jacket with the pump housing, and rotor assembly both ends are designed with master
Balance weight and secondary balance weight.The torque T1 that the weight of main balance weight generates, secondary balance weight generate production torque T2, the production of eccentric part weight
Raw torque T3, operates steadily to reach, their relationship is T1=T2+T3.
Since there is bearing at the both ends of eccentric part, in order to balance the torque of eccentricity generation, the main balance weight and pair of design
Balance weight can be influenced by the length of rotor, also by the effect length of upper bearing (metal), poor universality, and whole dynamic balance ability
Difference, easily because fuel feeding not in time when due to generate big abrasion, also easily because motor stator and rotor clearance lead to magnetic pull extremely
Abnormal caused frictional resistance increase, it is caused to start exception.
Utility model content
The main purpose of the utility model is that a kind of pump housing and compressor are provided, to solve compressor of the prior art
It is susceptible to abnormal the problem of starting.
To achieve these goals, one side according to the present utility model provides a kind of pump housing, including bent axle, institute
It states bent axle and includes the first crankshaft section and the second crankshaft section, pass through elastic member between first crankshaft section and second crankshaft section
Part is connected as one.
Further, the elastic element is spring, and the spring is set in first crankshaft section and second song
Shaft part is connected the periphery at position.
Further, first positioning hole is provided on first crankshaft section, second is provided on second crankshaft section
Location hole, the first end of the spring are fixed in the first positioning hole, and the second end of the spring is fixed on described second
In location hole.
Further, it is provided with spliced eye on first crankshaft section or second crankshaft section.
Further, the pump housing further includes the first balance weight and the second balance weight, first balance weight and described
Two balance weights are separately fixed on first crankshaft section and second crankshaft section.
Further, first balance weight and second balance weight are separately fixed at first song by locking member
On shaft part and second crankshaft section.
Further, there is gap between the interior sidewall surface of the spring and the bent axle.
Further, positioning groove, the two are provided in first crankshaft section and the second crankshaft section one of both
The positioning protrusion being adapted with the positioning groove is provided on another.
Further, the outer diameter of first crankshaft section and second crankshaft section is equal or different.
Further, the elastic element is spring, and the spring is set in the periphery of the positioning protrusion, and the bullet

Another aspect according to the present utility model provides a kind of compressor, and including the pump housing, the pump housing is above-mentioned pump
Body.
Using the technical solution of the utility model, due to the bent axle of the pump housing in the utility model include the first crankshaft section and
Second crankshaft section, and pass through elastic element and be connected as one the first crankshaft section and the second crankshaft section, when motor rotates, first
The first crankshaft section is driven to rotate, rotor turns an angle after T, then drives elastic element torsion, and then drive the second bent axle
Section rotation, and then the pump housing is promoted to rotate.
When resistance such as the pump housing has abnormal (non-stuck state), such as fluid is compressed, suction and discharge lack of equilibrium pressure etc., rotor
The angle T degree of rotation becomes much larger, and increases the elastic force of elastic element, the resistance until meeting and exceeding the pump housing promotes to pump
Body rotates；Resistance such as the pump housing has close to stuck state, and resistance is significantly bigger than motor force, then the angle T degree of rotor rotation reaches
To after maximum angle, rotor rotation speed zero, the elastic force of elastic element is also bigger than motor force at this time, and rotor generates reversion, instead
After going to t degree, the elastic force of elastic element reduces to the ability that can not be further continued for reversion, i.e. rotor speed is also zero, in motor force
Under effect, rotor rotates again.Due to rotating every time, fraction whirling vibration is all generated, the pump housing slowly turning by a small margin can be made
Dynamic, until the pump housing leaves stuck point, the pump housing can smooth rotation.
As it can be seen that the pump housing of the utility model is suitable for the startup of compressor worst cold case and frequent starting situation, carry
High customer satisfaction；It also is able to reduce the startup requirement to motor, the efficiency of motor can be improved in design, reduce compressor work
Consumption improves compressor performance.
