How to install centrifugal compressor in clean workshop?

Unpacking of centrifugal compressors should be carried out from top to bottom. When unpacking, care should be taken to protect the pipelines, instruments and electrical equipment of the unit from damage. After unpacking, check the number of accessories and whether the unit is inflated for leakage. , the internal pressure of the unit inflated should comply with the pressure specified in the equipment technical documents; before the unit is connected to the compressor intake pipe, the guide vanes and actuators, the blade opening and the indicated position should be observed from the suction port, and adjusted according to the requirements of the equipment technical documents. Position, and finally connect the electric actuator; high-pressure oil-resistant asbestos rubber gaskets should be used at the flange connection of the unit; after the unit is hoisted into place, the center should be coincident with the foundation axis, and two or more parallel units should be on the unified datum elevation line. The allowable deviation is ±10mm; the centrifugal refrigeration compressor should be aligned with the longitudinal level on the main shaft, and its level should not exceed 0.03‰, and the horizontal level should be aligned on the sub-surface in the casing, and its level should not exceed 0.1‰; The level should be aligned on other processing planes parallel to the bottom surface of the compressor, and the vertical and horizontal unevenness should not exceed 0.1‰.

The assembly sequence is dismantling first, then assembly, first inside and outside, first assembling into components and then final assembly; the assembled parts should be coated with refrigerated oil, and they should rotate flexibly after assembly; after the unit body is assembled, assemble the instrument, safety protection , automatic control pipeline, water cooling pipeline and other parts, the fasteners should be evenly tightened, and the locking thrust piece should be able to work; before connecting the compressor intake pipe, the guide vanes and actuators should be observed through the air intake , as well as the blade opening and the indicator position of the instrument, and should be adjusted and positioned according to the requirements of the relevant equipment technical documents, and then connected to the electric actuator; the single adjustment equipment should be debugged before the control equipment is installed, and the primary instrument installed on site should be Instruments installed in a location with sufficient light and convenient measurement, and installed directly on the cooling water and frozen water pipelines, should be installed before the pressure test after the pipeline is purged to ensure the tightness of the interface, and the wire number should be marked at the wiring. Semi-hermetic centrifugal compressors generally do not need to be disassembled and cleaned, but the oil tank and oil circuit should be cleaned to keep the oil circuit unblocked. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean workshops and clean workshop projects.

If the centrifugal compressor in the clean workshop has exceeded the time limit specified in the technical documents, or there is damage and corrosion in the appearance inspection, it should be comprehensively inspected and disassembled for cleaning, and the clearance of each part should be adjusted according to the provisions of the technical documents; the required equipment should be prepared before disassembly. When dismantling and washing, the positioning and direction marks should be made; drain the oil in the crankcase, open the crankcase cover, and remove the instruments, water cooling pipes and other parts at the same time; disassemble the removed parts for inspection, cleaning, Measurement; all oil holes should be unobstructed and clean, the oil filter should be complete and clean, the suction and exhaust valve groups should be tested for oil penetration, and no more than 5 drops per minute should be qualified, and the high and low pressure valves should be tested for sealing; Run-in and contact conditions.
