Abstract
The utility model discloses a low-noise and variable-frequency screw air compressor, which comprises a casing, a chassis connected with the casing and an oil circulating system, wherein the chassis is provided with an oil-gas separator and a machine base, the machine base is provided with a screw host machine and an electric motor; the electric motor is an oil-cooling electric motor consisting an oil supply circuit and an oil drainage circuit, the oil supply circuit and the oil drainage circuit are respectively connected into the oil circulating system, and the oil supply circuit is the upstream of the oil drainage circuit. According to the utility model, an air-cooling electric motor is changed into the oil-cooling electric motor, and cooling oil is introduced into the oil circulating system of the compressor, so that the oil circulating system can be utilized effectively; and after the oil-cooling electric motor is adopted, noises are reduced greatly.
Description
(1) technical field
The utility model relates to a kind of frequency conversion screw air compressor.
(2) background technique
The noise source of frequency conversion screw air compressor is except coming from screw host, unit fan and pipeline etc., and the noise that motor sends also is a very important ring; Ventilated motor cools off the noise that the fan that carries can produce air-flow for self, and this is inevitable; In addition, ventilated motor because of cooling air quantity is not enough, has limited the slewing range of unit when low speed.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing technology, the utility model provides a kind of noise lower frequency conversion screw air compressor.
The technological scheme that the utility model solves its technical problem is:
A kind of low noise frequency conversion screw air compressor comprises cabinet and the chassis that is connected cabinet, and deaerator and support are installed on the chassis; Screw host and motor are installed on the support; Also include the recycle oil system, described motor is a but motor of oil cooling, and described oil cooling but motor includes fuel feeding road and oil extraction road; Described recycle oil system is inserted on described fuel feeding road and oil extraction road respectively, and described fuel feeding road is the upper reaches on oil extraction road.
As preferably, the recycle oil system comprises the oil pipe that connects deaerator, and described oil extraction road connects the oil pipe of described deaerator.
Change ventilated motor into oil cooling but motor; Be that motor cools off through cold oil; And cold oil is linked into the recycle oil system; The fuel feeding road and the oil extraction road that are about to connect motor are linked into the recycle oil system, and the pressure difference of compressor capable of using self circulates, and effectively utilizes the recycle oil system.
The beneficial effect of the utility model is: the utility model changes to but motor of oil cooling with ventilated motor; And cold oil is linked into the recycle oil system of compressor; Can effectively utilize the recycle oil system, and adopt oil cooling but behind the motor, significantly reduce noise.
(4) description of drawings
Fig. 1 is the structural representation of the utility model.
(5) embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
As shown in Figure 1, a kind of low noise frequency conversion screw air compressor comprises cabinet 3 and the chassis that is connected cabinet 4; Deaerator 2 and support 7 are installed on the chassis 4, screw host and motor 6 are installed on the support 7, also include the recycle oil system; Motor 6 is a but motor of oil cooling; Oil cooling but motor includes fuel feeding road 5 and oil extraction road, and described recycle oil system is inserted on fuel feeding road and oil extraction road respectively, and the fuel feeding road is the upper reaches on oil extraction road.The recycle oil system comprises the oil pipe 1 that connects deaerator, and the oil extraction road connects the oil pipe 1 of described deaerator.
Change ventilated motor into oil cooling but motor; Be that motor 6 cools off through cold oil; And cold oil is linked into the recycle oil system; The fuel feeding road and the oil extraction road that promptly connect motor are linked into the recycle oil system, and the pressure difference of compressor capable of using self circulates, and effectively utilizes the recycle oil system.The utility model changes to but motor of oil cooling with ventilated motor, and cold oil is linked into the recycle oil system of compressor, can effectively utilize the recycle oil system, and adopts oil cooling but behind the motor, has significantly reduced noise.
Claims (2)
1. a low noise frequency conversion screw air compressor comprises cabinet and the chassis that is connected cabinet, and deaerator and support are installed on the chassis; Screw host and motor are installed on the support; Also include the recycle oil system, it is characterized in that: described motor is a but motor of oil cooling, and described oil cooling but motor includes fuel feeding road and oil extraction road; Described recycle oil system is inserted on described fuel feeding road and oil extraction road respectively, and described fuel feeding road is the upper reaches on oil extraction road.
