Compared with ordinary compressors, they have high energy efficiency, strong adaptability, and high reliability, and have been used more and more widely. Therefore, the performance test of this type of compressor is of great significance.

[0004] Although the above-mentioned screw compressor test bench improves the convenience of detection, the screw of the screw compressor needs to be installed and connected to the output shaft of the motor before detection. However, during installation, due to the heavy weight of the screw compressor, the installation accuracy is not high, and improvements are made to this end. Summary of the invention

[0005] The purpose of the present application is to provide a test device and a test method for a screw compressor in order to solve the above-mentioned technical problems, so as to improve the convenience of installing the screw compressor and the drive motor and to have a higher installation accuracy.

[0012] Wherein, the detection mechanism includes a laser transmitter, a laser receiver, and an adjustment component, the adjustment component is used to control the rotation adjustment of the laser transmitter and the laser receiver, and the laser transmitter corresponds to the laser receiver.

[0013] The driving motor is installed on the motor test stand through fasteners, and the compressor test stand and the motor test stand are connected through fasteners. After the screw compressor is placed on the compressor test stand, the screw compressor is adjusted through the adjustment system, and the position of the screw shaft of the screw compressor is detected through the detection mechanism. After the adjustment is completed, the screw compressor is installed and connected to the output shaft of the driving motor, and the test system is installed and connected to the tested screw compressor. The test system is used to detect various performances of the screw compressor, including exhaust pressure, exhaust flow rate, operating temperature, etc. The detection mechanism is used to detect the position of the screw shaft of the screw compressor and the output shaft of the driving motor through a laser transmitter and a laser receiver. The position of the laser transmitter and the laser receiver is adjusted through the adjustment component to control the axis of the screw shaft of the screw compressor to be the same as the axis of the output shaft of the driving motor, thereby improving the installation accuracy, and cooperating with the adjustment system to improve the convenience of adjusting the screw compressor, saving time and effort.

[0014] Furthermore, the adjustment component includes:

[0016] A rotating seat, movably mounted on the adjusting base;

[0017] A first gear ring is mounted on the rotating seat;

[0018] A first gear is mounted on the adjustment base;

[0019] A first adjusting motor is installed on the adjusting base and is connected to the first gear;

[0020] Wherein, the laser transmitter and the laser receiver are movably mounted on a rotating seat;

[0021] The adjusting base is placed on the motor stand, and the rotating base is movably installed on the adjusting base.

[0022] Furthermore, the rotating seat comprises:

[0023] The slide seat is respectively installed and connected with the laser transmitter and the laser receiver;

[0030] Wherein, the sliding seat is provided with two sliding blocks.

[0031] The laser transmitter and the laser receiver are both equipped with a slide seat, which cooperates with the slider through the slide groove on the rotating seat. The slider and the slide seat are slidably connected, and the slider is hinged to the first rack. There are two slides on the same slide seat, and the second gear is controlled to rotate by the second adjusting motor. The second gear is meshed with the first rack, and the first rack is movably installed on the slide seat, so as to control the slider to move toward or oppositely on the slide seat, so that the slider is placed in the slide groove and moves. At the same time, the slide seat is controlled to move along the axis direction of the telescopic rod in cooperation with the telescopic rod.
