Technical field

The utility model belongs to technical field, more particularly, to a kind of cooling system of air compressor.

Background technology

At present, water-cooled air compressor cooling system on the market is all independent control (equipment manufacturer's portless is reserved), in sky In the case that press is shut down, water pump will not be shut down, and when system is not used, water pump still needs to consume the substantial amounts of energy, increases Production cost.

Utility model content

The utility model is for overcome the deficiencies in the prior art, there is provided a kind of cooling system of air compressor of energy-conserving and environment-protective.

To achieve these goals, the utility model uses following technical scheme：A kind of cooling system of air compressor, including sky Press, the water pump and radiator fan being connected with air compressor machine；Also include one and shut down control module, the shutdown control module is by pneumatics The major loop that power supply, zero sequence current mutual inductor, relay and the contactor of machine are formed, the zero sequence current mutual inductor and relay It is connected, the relay is connected with contactor, and the contactor is connected with water pump.The utility model can lead to when air compressor machine stops Cross shutdown control module control water pump to stop, preventing water pump long-time no-load running, reduce unnecessary energy consumption, reduction is produced into This, realizes energy-conserving and environment-protective.

Further, the water pump includes housing and the impeller in housing, the impeller include drive shaft and with institute State multiple blades that drive shaft is detachably connected；Blade can be dismantled, change the blade at different size or angle of inclination, make The water yield of water pump, go out water speed etc. and changed, the scope of application is wider；And because blade can be dismantled individually, can be Leaf destruction is individually replaced when damaging to blade, is reduced maintenance cost, is increased the service life.

Further, what is be spaced in the drive shaft is distributed with multiple link slots, and the blade is provided with and link slot phase The plug division of cooperation, coordinate between the plug division and the link slot for anticreep；It is real by the cooperation of plug division and link slot Both existing dismounting, it is easy to operate, it is simple in construction, it is hardly damaged.

Further, the link slot top has the opening for being available for the plug division insertion, and the drive shaft top can Dismantling connection one is used for the end cap for closing the opening；The direct volume in plug division inserts link slot at the upper opening of link slot Interior, assembling is easy；The setting of end cap effectively can prevent blade from departing from drive shaft, and both are connected firmly, service life length.

Further, the end cap and the drive shaft are threaded, the locking direction of the end cap and the rotation of drive shaft In the opposite direction；Because the locking direction of end cap and the rotation direction of drive shaft are on the contrary, during drive shaft turns, its by During opposite with rotation direction resistance, end cap will not be by turn.

Further, the end cap is provided with the screw that can be connected with the drive shaft；So that the connection of end cap and actuator It is more firm.

Preferably, the plug division corresponds to blade side provided with symmetrically two convex tendons are provided with, and is set in the link slot In the groove being engaged with the convex tendon；Convex tendon and the cooperation of groove can effectively prevent the relative link slot in plug division from rocking, blade It is hardly damaged, increases the service life.

In summary, the utility model has advantages below：Can be when air compressor machine stops by shutting down control module control Water pump stops, and prevents water pump long-time no-load running, reduces unnecessary energy consumption, reduces production cost, realizes energy-conserving and environment-protective.

Embodiment

In order that those skilled in the art are better understood from the utility model, it is real below in conjunction with the utility model The accompanying drawing in example is applied, clear, complete description is carried out to the technical scheme in the embodiment of the utility model.

As Figure 1-5, a kind of cooling system of air compressor, including air compressor machine, the water pump and radiation air that are connected with air compressor machine Fan；The air compressor machine and radiator fan are prior art, are not being repeated；Also include one and shut down control module 2, specifically, stopping Machine control module 2 is that the master being made up of the power supply 21 of air compressor machine, zero sequence current mutual inductor 22, relay 23 and contactor 24 returns Road, the zero sequence current mutual inductor 22 are connected with relay 23, and the relay 23 is connected with contactor 24, the contactor 24 It is connected with water pump；Zero sequence current mutual inductor 22, relay 23 and contactor 24 are that prior art can be realized, concrete structure and original Reason is not repeating；By shutting down control module water pump can be controlled to stop when air compressor machine stops by shutting down control module 2, specifically Process is as follows：When the power supply 21 of air compressor machine disconnects, zero sequence current mutual inductor produces a signal, and signal passes through major loop transmission To relay, control relay action so that the normally-closed contact of contactor disconnects, so as to have the function that water pump stops.

The water pump 1 includes housing 11 and the impeller 12 in housing, the impeller 12 include drive shaft 121 and with Multiple blades 122 that the drive shaft is detachably connected；Blade is preferably 5, is spaced on the outer surface of the drive shaft 121 Multiple link slots 31 are distributed with, the number of link slot 31 is preferably 5；One end that the blade 122 is connected with drive shaft has Plug division 32, the plug division 32 can coordinate with the grafting of link slot 31, and be anticreep between plug division 32 and the link slot 31 Coordinate, during effectively preventing wheel rotation, blade is thrown out of；In order to facilitate installation blade, the top of link slot 31 tool There is an opening 311, the plug division 32 can be inserted into link slot 31 by the opening 311, and assembling is convenient；In order to prevent blade from sending out Life is rocked, and we are provided with two convex tendons 321 on the side that the plug division 32 is connected with blade, and two convex tendons 321 are symmetrical Set；Two grooves 312 are provided with the link slot 31, when plug division is connected with link slot, convex tendon 321 can be inserted with groove 312 Cooperation is connect, effectively prevents plug division double swerve in inner link slot, so as to blade be caused to rock.

Further, the top of drive shaft 121 is detachably connected an end cap 4, can be right when end cap is connected with drive shaft The opening on link slot top is closed；Specifically, the end cap 4 and the drive shaft 121 are threaded, and end cap 4 It is opposite with the rotation direction of drive shaft 121 to lock direction；In order that the connection for obtaining both is more firm, we set on end cap 4 Multiple screws 5 have been put, after end cap is spirally connected with drive shaft 121, end cap and drive shaft can be connected by screw 5, end cap is not easy Abjection.
