Description
Technical field
The invention belongs to pump technical field, spy is related to a kind of four cylinder slide valve pump of parallel connection using automatic balancing rotor group.
Background technique
As a kind of common oil seal type oil-sealed rotary pump, slide-valve vacuum pump is a kind of positive-displacement vacuum pump, it can be with
The volume for changing suction chamber by the mechanical rotation of slide valve, achievees the purpose that pumping by the movement of rotor.It is suitable for
It removes general gas or contains a small amount of condensed gas, be widely used in every field.
The primary structure of side valve type vacuum includes the pump housing, eccentric wheel, slide valve assembly and guide rail etc..Due to slide-valve vacuum pump
Rotor quality has compared with large eccentricity, and good mass balance, can not generate larger vibration in the running.Simultaneously because the rotation of slide valve pump
Pignus pignoris heart motion profile is complicated closed curve, therefore is difficult to realize the complete equipilibrium to slide valve pump inertia force.This is just limited
The revolution of slide-valve vacuum pump, general control are a other to can reach 1000r/min or more in 350~600r/min.
The method for solving this unbalance inertia force at present, mainly there is the following aspects:
The sliding valve vacuum pump of " 1. double-cylinder structure ".One long and short two pump group is combined, shares an axis, two partially
Heart wheel reversing device on axis, and distribution of weight block appropriate is added on driving pulley.This structure is widely used in
In the Earlier designs of slide valve pump.But practice have shown that in this configuration, the harmonic wave inertia force of odd number can only be balanced, and due to knot
The asymmetry of structure, it can also generate additional moment on the pump housing, so that the balance to pump has an impact.
" 2. triple balancing techniques ": centre is a long cylinder, and respectively there is an isometric cylinder at both ends, and three groups of slide valves are by one
Common axis drives simultaneously, and there is one group of slide valve in centre, and twice of its two groups of slide valves of length and weight-type both ends.When the pump is operated,
Phase difference between two groups of short slide valves and intermediate long slide valve remains between 180 °.The inertia force that long slide valve generates is F, short
The inertia force that slide valve generates is F/2, therefore the inertia force and moment of inertia that pump are equal in magnitude and contrary.However in this knot
In structure, the harmonic wave inertia force of odd number can only be balanced as " double-cylinder structure ", he compares advantage with " double-cylinder structure " and is structure
Symmetrically, additional moment will not be generated on the pump housing.
3. moving balance hole on eccentric wheel by analytical calculation.Because the reasons such as mismachining tolerance can not perfectly disappear
Except the eccentricity issues of eccentric wheel.
4. stabilizer is added, and additional clump weight over pulleys carried, to be balanced to the inertia force of eccentric wheel and slide valve
Vibration damping.These modes are similar to " double-cylinder structure ", can only balance the harmonic wave inertia force of odd number, and due to the asymmetry of structure
Property, it can also generate additional moment on the pump housing, so that the balance to pump has an impact.
5. mechanical damping device: for express pump and mammoth pump, vibration can be reduced with the method for addition mechanical damping device
It is dynamic.Such as rubber shock absorber is installed on the pedestal of pump and carrys out vibration damping.This mode can only play slide valve eccentric vibrating certain
Inhibiting effect can not completely eliminate, while also add the load of pedestal and fot screw.
Above all of mode and means can only partially remove the eccentric vibrating of eccentric wheel, can not be completely counterbalanced by bias
The centrifugal intertia force that wheel and sliding valve movement generate, and the centrifugal intertia force generated for sliding valve movement does not suggest that and rationally may be used
The solution leaned on.
In addition to the problem on shock absorption principle, there is also deficiencies on conventional spool valves pump configuration, specific as follows:
Conventional spool valves pump entrance and exit and pump chamber between channel it is very short, almost without position come design runner, improve stream
Dynamic state is unfavorable for reducing suction and discharge noise；There is also the situations that pump oil is splashed for air inlet, when pumping hole and system direct connection, easily
The accident that pump oil enters system occurs.
In the slide valve pump tradition type of cooling, without this structure of cooling water channel, have plenty of bulky cooling water cavity, pumps
Chamber is almost immersed in cooling water cavity, although contact area is sufficiently large, because cooling water cavity volume is big, and the cooling water of high speed
Slowing down rapidly from flow velocity after cooling nozzle inflow cooling water cavity, the speed for causing cooling water to flow through pump chamber heat exchange surface is very low,
And again because of its interior shape complexity, each section flow velocity is uneven, flows through that distance is short, and a large amount of cooling water exchanges heat not in time is arranged
Out, cause cooling efficiency low, cooling effect is poor.Moreover, traditional cooling water cavity and the working chamber that is dipped in cooling water it
Between support construction it is few, pump housing easily vibrates.

A. cooling effect is promoted:
In the slide valve pump tradition type of cooling, without this structure of cooling water channel, have plenty of bulky cooling water cavity, pump chamber
Almost be immersed in cooling water cavity, although contact area is sufficiently large because cooling water cavity volume is big, the cooling water of high speed from
Flow velocity slows down rapidly after cooling nozzle flows into cooling water cavity, and the speed for causing cooling water to flow through pump chamber heat exchange surface is very low, and
Again because of its interior shape complexity, each section flow velocity is uneven, flows through that distance is short, and a large amount of cooling water exchanges heat have been discharged not in time,
Cause cooling efficiency low, cooling effect is poor.
Novel water cooling system has inside and outside two parts cooling water channel of connection, and coolant liquid is flowed into from internal water channel again from outside
Water channel outflow, using this structure, traditional type of cooling, coolant liquid are significantly increased in the intracorporal distance that flows through of pump compared with；To make
It is cooling more evenly, by inside and outside cooling water channel it is average be divided into several water channels, every water channel section is identical, but because cross section of fluid channel compared with
It is small, therefore flow velocity loss is far below traditional type of cooling, although the cooling water of high speed is uniformly divided into after cooling nozzle entrance
Multiply, but appoint and can flow successively through the inside cooling water channel that opens up on the pump housing and external cooling water channel with identical high flow velocities, it is cold
But the speed that liquid stream crosses heat exchange surface greatly promotes compared with traditional type of cooling；Cooling water channel inner surface is designed to and pump chamber phase
Same arc surface, heat exchange area is big, and heat exchange is uniform；The effect in conclusion novel water cooling system exchanges heat compared with traditional type of cooling
Rate is obviously improved, and cooling effect greatly enhances.
B. stability is improved:
Slide valve pump itself there is a problem of vibrating big, traditional cooling water cavity and the support being dipped between the working chamber in cooling water
Structure is few, and pump housing easily vibrates.The immersion structure that novel water cooling system discards tradition, using water channel type structure, so that
The pump housing must support pump chamber more firm, and pump chamber is not susceptible to vibrate compared with traditional type of cooling, and stress is more balanced everywhere, improve
Its durability.
