Abstract
The utility model discloses a kind of helical-lobe compressor fuel feeding pressurizer, belong to Compressor Technology field, it includes pressure oil pump, time-delay relay and pressure difference switch, pressure oil pump is arranged on the oily transfer pipeline for connecting compressor oil groove and compressor displacement regulating piston cylinder, pressure oil pump is connected with time-delay relay, and time-delay relay is connected with pressure difference switch.Utilize this utility model can make compressor Effec-tive Function under full load state, meet compressor and use the requirement of side load.
Description
Technical Field
The utility model belongs to the technical field of the compressor, especially, relate to a screw compressor fuel feeding supercharging device.
Background
When the screw compressor is loaded, the full load is realized by adjusting the position of the capacity adjusting valve block, the realization of the process needs to rely on certain oil pressure to push the capacity adjusting valve block to move to the full load position, and the oil pressure is generated by the pressure difference between the exhaust gas and the suction gas of the compressor. When the working conditions of the evaporation side and the condensation side of the unit are close, and the pressure difference between the exhaust pressure and the suction pressure of the compressor is lower than the pressure required by the sliding of the capacity regulating valve block, the capacity regulating valve block of the compressor is positioned at a partial load position, so that the output capacity of the compressor cannot meet the load requirement of the use side.
It will thus be seen that the prior art is susceptible to further improvements and enhancements.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an avoid the weak point that above-mentioned prior art exists, provide a screw compressor fuel feeding supercharging device, the device makes the compressor can be high-efficient operation under full load state, satisfies the requirement of using the side load.
The utility model discloses the technical scheme who adopts does:
screw compressor fuel feeding supercharging device, including booster oil pump, time delay relay and differential pressure switch, the booster oil pump sets up on being used for connecting the oil delivery pipeline that compressor oil groove and compressor held the transfer piston cylinder, and the booster oil pump links to each other with time delay relay, and time delay relay links to each other with differential pressure switch.
Since the technical scheme is used, the utility model discloses the beneficial effect who gains does:
1. the requirement can not be reached at helical-lobe compressor operating oil pressure, and when the compressor holds the valve piece of transferring and is in the non-full load state, in time start the utility model provides a supercharging device can make the compressor high-efficient operation under the full load state, fully satisfies the requirement of user side.
2. The utility model discloses simple structure, installation easy maintenance and cost of manufacture are lower.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments, but the present invention is not limited to these embodiments.
As shown in figure 1, the screw compressor oil supply supercharging device comprises a supercharging oil pump 4, a delay relay 3 and a pressure difference switch 2, wherein the supercharging oil pump 4 is arranged on an oil conveying pipeline of a compressor oil groove and a compressor capacity adjusting piston cylinder, the supercharging oil pump 4 is connected with the delay relay 3, and the delay relay 3 is connected with the pressure difference switch 2.
The working principle of the supercharging device is as follows: after the compressor is started, the gas pressure at the gas inlet 1 and the gas pressure at the gas outlet 5 are transmitted to the differential pressure switch 2, when the difference between the exhaust pressure and the suction pressure is smaller than the set value of the differential pressure switch 2, the differential pressure switch 2 transmits a signal to the delay relay 3, if the differential pressure switch 2 continuously inputs the signal to the delay relay 3 within the set time of the delay relay 3, the delay relay 3 outputs the signal to the booster oil pump 4 after reaching the set time, the booster oil pump 4 is started to increase the oil pressure, and the compressor capacity adjusting slide block is pushed to move to the full load position, so that the output capacity of the compressor is increased; if the signal from the differential pressure switch 2 obtained by the delay relay 3 in the set time is interrupted, namely the pressure difference between the exhaust pressure and the suction pressure is greater than the set value of the differential pressure switch 3, the delay relay 3 stops the action, and the booster oil pump 4 is not started.
The parts not mentioned in the utility model can be realized by adopting or using the prior art for reference.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
