The Environment In Which The Blood Bank Centrifuge Runs Well Is The Foundation

Oct 31, 2013

Blood bank centrifuge operating environment must have certain requirements, first of all, the temperature should not be too bad, secondly, the station should be stable, and finally the voltage!

Especially in the space that has been in action, such as some cars, we often have a blood donation car. This is also a car that needs a Blood bank centrifuge. At this time, it is said:

The engine room air conditioner crankcase is evacuated and refueled. First close the liquid supply valve and the suction valve. When the crankcase pressure is slightly lower than the atmospheric pressure, open the fueling valve. The oil enters the crankcase through the oil filling valve under atmospheric pressure. When the oil level requirement is reached, the fueling valve is closed, and the large compressor suction valve and the related liquid supply valve are gradually opened to resume normal operation. The engine room air conditioner special oil pump is refueling. When the compressor needs to be refueled, connect the oil pump, oil pipe and oil accumulator to the compressor. Just start the oil pump and open the compressor refueling valve. It does not affect the compressor operation and is conducive to the sanitation of the machine room.

The problem of abnormal noise in the vehicle when using the air conditioner is also criticized by the owner, and it is often difficult to be discovered in time due to seasonal limitations. There are several reasons for the abnormal noise: First, excessive refrigerant may cause abnormal noise in the air conditioning system; in addition, there are more abnormal problems in air conditioner compressors and blowers. It has been found that the air-conditioning noise of some vehicles has exceeded 100 decibels, which seriously affects the comfort of driving. According to industry insiders, the abnormal noise of blowers is mainly caused by fan motor bearings. One reason is due to the quality of the bearing itself, or it may be due to the poor purification effect of the air conditioning filter, the dust enters the air duct, causing the bearing to wear and cause axial turbulence.

No matter how good the environment and regular operation, you can't avoid the "careful" Blood bank centrifuge strike, don't worry, it's usually a small problem!

The Blood bank centrifuge can not start at low speed when it is cold. The Blood bank centrifuge oil solidifies or the lubricant deteriorates and sticks. At the beginning, you can use your hand to help re-rotate or clean and then re-oil. Blood bank centrifuge vibration is severe, noise is big. Trouble: Check if the Blood bank centrifuge has imbalance. The nut of the fixed machine is loose. If it is, tighten it. Check the Blood bank centrifuge bearing for damage or bending. Replace the bearing if available.

Check the Blood bank centrifuge cover for deformation or incorrect position. If necessary, adjust it. The vibration excitation of the Blood bank centrifuge system is: motor drive system, screen basket and machining error, bearing and bracket, assembly of unbalanced shaft, formation of crack rupture chamber water in vitro, problems caused by excessive temperature failure, high centrifugal severity, high speed The rotation axis is tilted and vibrated. When the vibration frequency exceeds the limit, it will cause the Blood bank centrifuge of the whole system to resonate, resulting in serious consequences. Therefore, whether the Blood bank centrifuge or other Blood bank centrifuges need to pay attention to the vibration of the Blood bank centrifuge during the application, because this pair The normal use and safety of the Blood bank centrifuge have a major impact.
