Abstract
The invention relates to a cooling method for a screw air compressor, which can fully cool the air compressor. The technical scheme is that the heat of the screw air compressor is dissipated through a blower; the cooling method for the screw air compressor is characterized in that the starting of the blower is controlled by an intermediate relay; a intermediate relay contact and a blower contactor are connected to a power supply in series; and the intermediate relay is connected with a standby normally closed contact of a field emergency stop button of the screw air compressor.
Description
Technical field
The present invention relates to a kind of cool-down method of screw air compressor.
Background technique
In the prior art, owing to air compression and friction-produced high temperature, need electric fan to dispel the heat during the screw air compressor operation, as shown in Figure 1, control mode is the PLC program control, and electric fan contactor 1 is opened with screw air compressor and disconnected, and causes the air compressor heat radiation time not enough.Air compressor fuselage detected temperatures reaches 100 ℃ and promptly causes the overheating fault shutdown not move, and source of the gas is supplied with and interrupted causing producing stopping.Simultaneously, compressor oil temperature height is perishable, moves just need change compressor oil, filter in about 200 hours.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of cool-down method of screw air compressor, and air compressor is fully lowered the temperature.
Realize the technological scheme of the object of the invention:
A kind of cool-down method of screw air compressor, screw air compressor dispels the heat by blower fan, it is characterized in that: the startup of blower fan is controlled by auxiliary reclay.
Auxiliary reclay contact and the series connection of blower fan contactor are to power supply.
Auxiliary reclay is connected with the standby normally-closed contact of on-the-spot emergency stop button of screw air compressor.
The beneficial effect that the present invention has:
Blower fan of the present invention is controlled by auxiliary reclay, auxiliary reclay is connected with the standby normally-closed contact of on-the-spot emergency stop button of screw air compressor, the start and stop of blower fan and the start and stop of air compressor are no longer synchronous, make air compressor can access abundant cooling, the air compressor controllable temperature is built in below 85 ℃, guarantee stable operation, avoided the frequent situation about changing of consumptive material, reduced spare parts demand and changed frequency.
Description of drawings
Fig. 1 is the circuit theory diagrams of existing screw air compressor control section;
Fig. 2 is the circuit theory diagrams of screw air compressor control section of the present invention.
Embodiment
As shown in Figure 2, auxiliary reclay contact K1 and 2 series connections of blower fan contactor are to power supply, auxiliary reclay K connects with the standby normally-closed contact J of the on-the-spot emergency stop button of screw air compressor, the break-make of blower fan contactor 2 is by auxiliary reclay k and the control of on-the-spot emergency stop button, no longer synchronous with the start and stop of air compressor, make air compressor can access abundant cooling.
Claims (3)
