Installation of refrigeration compressor in purification pharmaceutical cleanroom
Screw refrigeration compressors are air-cooled and water-cooled. The main engine includes fully enclosed vertical screw compressors and semi-hermetic horizontal screw compressors. It is directly connected to the motor through an elastic coupling, and is connected to the oil separator and oil separator. The condenser and other components are set on the same support; the foundation should be leveled and aligned during installation, and its vertical and horizontal unlevels should not exceed 1‰; the suction and exhaust pipes should be cleaned before the compressor is connected, and the pipes should be used as necessary. When connecting, care should be taken not to deform the unit and affect the alignment of the motor and the screw refrigeration compressor; after the grouting strength meets the requirements, the equipment should be finely leveled, and the dial indicator should be used on the end face and circumference of the coupling. Measurement and alignment, the allowable deviation should comply with the provisions of the equipment technical documents; after the unit is in place, the rubber transmission core in the coupling hole should be disassembled to separate the motor from the compressor, install the electrical part and connect the power supply of the motor. Drive the motor and confirm that the rotation direction of the motor is consistent with the technical documentation of the unit. The compressor is directly connected to the motor and installed on the same frame. In order to ensure the safe operation of the unit, the lower part of the unit is equipped with an oil separator, an oil cooler, an oil pump and an oil filter, and a safety protection device is installed beside the unit.
Lithium bromide absorption refrigeration equipment uses lithium bromide solution to absorb water vapor at room temperature, and can release the absorbed water at high temperature, and use refrigerant water to absorb surrounding water when vaporized at low pressure The heat of the medium is used to achieve refrigeration. There are two types of refrigeration devices: overall equipment and assembly equipment. The overall equipment can be hoisted as a whole, and then leveled. The method is basically the same as that of centrifugal refrigeration units. The installation of assembly equipment should be : Lower cylinder → upper cylinder → heat exchanger → shield pump → vacuum pump → various pipes and components connected to the equipment. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for purification workshops and purification rooms.
The equipment should be placed on the basis of the hard rubber plate. The hard rubber plate can be placed according to the position of the feet, and its thickness is 10mm. After the equipment is in place, it should be leveled according to the datum plane specified in the equipment technical documents, and its vertical and horizontal unlevels should not exceed 1‰. Make sure that the water pan and the generator heating tube cluster are immersed in the solution to keep the outer surfaces of the rice steamer, absorber and heat exchanger in a good flow state; after the refrigeration system is installed, the interior of the equipment should be cleaned, and clean water should be added to the equipment during cleaning. , start the generator pump, absorber pump and evaporator pump to make the water circulate in the system for many times, and observe the color of the water until the inside of the equipment is clean; the shielding pump should be leveled, and the wire joints should be waterproof and sealed; When the heat exchanger is installed, the end with the discharge valve should be 20-30mm lower than the other end, so as to ensure that the solution can be easily drained when discharging.
