Problems to be aware of when debugging a double clean bench The debugging work of the equipment is very important. Let's take a look at the problems that should be paid attention to when debugging the double clean bench: 1. The ultra-clean workbench is rigorously tested before leaving the factory to ensure normal use. But this is not to say that the manufacturer's test can replace the operator to perform the necessary inspection and debugging before use. Because the environment in which the ultra-clean workbench is located is different, only after proper inspection and debugging can the equipment be used to a large extent. 2. Newly purchased and unused ultra-clean workbench, except for ultraviolet light, etc., can be fumigated, and then put an open nutrient at the four corners and the center of the operation area when the machine is in working condition. The agar plates were incubated with the lid for two hours and placed in a 37 ° C incubator for 24 hours to calculate the number of colonies. The average number of colonies per plate must be less than 0.5. 3. A better environment should be selected for the machine before commissioning. It is good to place it in a sterile room with an air disinfection facility. If the conditions are not available, the machine should be placed in a clean, clean room. Adjust the height of each foot to ensure a safe and level of operation. 4. The power supply of the ultra-clean workbench should use a special circuit to avoid the change of air flow rate caused by the overload of the circuit. Compared to the simple aseptic cover, the clean bench has a standard configuration that allows the operator to move freely, easily reach the operating area, and the UV lamp and lighting fluorescent lamp are standard on the ultra-clean workbench, which provides the power of air flow. Whether these components work properly is clear at a glance. The difficulty of zui is also important for Zui to check the air filter plate and its tightness, which is directly related to the normal use of the machine. The simple inspection method of zui is the nutrient agar plate method. Note: The power supply for the double clean bench is mostly three-phase four-wire. One of the zero wires is connected to the machine casing and should be connected to the ground wire. The other three wires are phase wires, and the working voltage is 380V. There is a certain order in the three-wire access circuit. If the wire is connected incorrectly, the wind is reversed. At this time, the sound is normal or slightly abnormal. The front of the clean bench is windless (the alcohol lamp can be used to observe the movement and the flame should not be tested for a long time). When the power is cut off in time, only the position of any two of the wires can be exchanged and connected. If the three-phase line is only connected to two phases, or one of the three phases is in poor contact, the machine sound is abnormal. You should immediately cut off the power supply and carefully repair it, otherwise the motor will be burnt. These common sense should be explained to the staff when they start using the ultra-clean platform. The exemption should not cause accidents and losses. pull out sofa bed,Sofa Beds,single sofa bed,double sofa bed Guangzhou LoPhiDa Co.Ltd , https://www.widinlsamachine.com
