[0032] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] Refer to Figures 1-4, A screw evaporative chiller 100 with fault detection, comprising: a unit body 101, a base 102, a fixing frame 103, a first spring 104, a damping block 105, and an adjustment assembly for adjusting the position of the damping block 105. The unit body 101 is fixedly connected to the fixing frame 103. The fixing frame 103 is vertically slidably connected to the base 102. Specifically, the base 102 is provided with a guide groove 102a extending along the height direction of the base 102, and the fixing frame 103 moves along the guide groove 102a. Both ends of the first spring 104 are fixedly connected to the fixing frame 103 and the base 102 respectively. A high-pressure detection pipe and a low-pressure detection pipe are arranged on the connecting pipeline of the unit body 101, and a first pressure sensor, a second pressure sensor, and a temperature sensor are arranged in the high-pressure detection pipe and the low-pressure detection pipe. The first pressure sensor, the second pressure sensor, and the temperature sensor are all signal-connected to a central processor, so as to detect the pressure value and temperature value inside the unit body 101. When the values exceed the set values of the central processor, the faults of the unit body 101 are detected, which is convenient for maintenance personnel to repair the unit body 101.

[0034] The adjustment assembly is used to adjust the position of the damping block 105, and includes: a fixing plate 106, a lead screw 107, a first slider 108, a transmission block 109, and a handwheel 110. The fixing plate 106 is fixedly connected to the fixing frame 103. The lead screw 107 is rotatably connected to the fixing plate 106. There are two fixing plates 106, which are respectively located at both ends of the lead screw 107. The first slider 108 is horizontally slidably connected to the fixing frame 103. Specifically, the fixing frame 103 is provided with a first chute 103a extending along the length direction of the fixing frame 103, and the first slider 108 moves along the first chute 103a. The transmission block 109 abuts against the first slider 108. The handwheel 110 is fixedly connected to the lead screw 107.

[0035] Among them, the first slider 108 includes a first inclined surface 108a, the transmission block 109 includes a second inclined surface 109a, and the first inclined surface 108a abuts against the second inclined surface 109a. The fixing frame 103 includes a first cavity 103c, and the fixing plate 106, the lead screw 107, and the first slider 108 are all located in the first cavity 103c. Both ends of the first spring 104 are fixed to the fixing frame 103 and the base 102 respectively. The damping block 105 is horizontally slidably connected to the fixing frame 103. The fixing frame 103 is provided with a second chute 103b extending along the width direction of the fixing frame 103, and the damping block 105 moves along the second chute 103b. The second chute 103b communicates with the first cavity 103c. There are two damping blocks 105 and transmission blocks 109, which are respectively located at both ends of the first slider 108. The base 102 is provided with a first clearance groove 102b for the handwheel 110 to move, and is arranged with a clearance from the handwheel 110. When the damping block 105 is worn after long-term use, rotate the handwheel 110. The rotation of the handwheel 110 drives the rotation of the lead screw 107, and the first slider 108 moves along the first chute 103a. Therefore, the rotation of the lead screw 107 drives the movement of the first slider 108, and the damping block 105 moves along the second chute 103b. Therefore, the first slider 108 drives the damping block 105 to move along the second chute 103b through the first inclined surface 108a and the second inclined surface 109a, thereby adjusting the position of the damping block 105.

[0036] Working process: During the working process of the unit body 101, it is shock-absorbed through the first spring 104 and the damping block 105 to prevent damage to the unit body 101 caused by vibration. At the same time, when the damping effect is reduced due to the wear of the damping block 105, rotate the handwheel 110. The rotation of the handwheel 110 drives the rotation of the lead screw 107, and the first slider 108 moves along the first chute 103a. Therefore, the rotation of the lead screw 107 drives the movement of the first slider 108, and the damping block 105 moves along the second chute 103b. Therefore, the first slider 108 drives the damping block 105 to move along the second chute 103b through the first inclined surface 108a and the second inclined surface 109a, thereby adjusting the position of the damping block 105. The position of the damping block 105 can be adjusted according to the shock-absorption requirements, and at the same time, the reduction of the shock-absorption effect caused by wear can be prevented.
