The tube should be free from dust and contamination during storage. 4.9 The tube must be stored in the screen, and the storage environment of the tube should be carefully considered. Should meet the requirements of the corresponding grade regulations of 4798.11,
4.10 The storage period of electric products is one year. The storage tubes must be checked or inspected twice a year, and records should be kept. Problems should be analyzed and dealt with in time. Electronic tubes with special requirements should be aged regularly according to the "Instructions for Use". 5. Installation and use of electronic tubes
5.1 When taking out the electronic tubes, the remaining yarn on the top and bottom should be cleaned up, and the tubes should be kept full (especially the porcelain tubes). Writing on the display is not allowed. The handle of the tube should be supported during loading and unloading. The anode flange or anode part should be placed with care to avoid collision and violent movement. In order to prevent the electronic filament from breaking or cracking, 5.2 Clean the tubes before installation and check whether they are in a cold state and high voltage. 5.2.1 Stop the tubes Before the second machine is installed, if there is dust on the tube, it should be handled properly. The method is as follows: for ordinary electronic tubes, use a soft cloth to wipe off the dust; for the original electronic tubes, use stationery to wipe it, and then use white alcohol to wipe it clean, or you can use soapy water and clean water to wash it, and then use a soft cloth to wipe it clean. 5.2.2 Pressure inspection according to 1.7 free escape. 5.2. 3 In the air temperature, a pair of electrodes of the tube are cooled to the high voltage state. The method is as follows: the electrons are liberated in the special range of training results, and the high-voltage test method (with the state-owned investment tube must be established) is used: for the "yin-world" period, the limit pole and one, the account is short-circuited and the pole is connected to the positive frequency commercial, for the "period" that "company sweeps the high voltage, and presses the day and presses the day to connect the two thumbs to the ground. For the "limit two arches" state, the anode is connected, and the cathode is published. Press the commercial voltage. The peak value of the high voltage between the electrodes should be reduced in accordance with the provisions of the "Instructions for Use". When the voltage is gradually increased from low to high, during the voltage rise process, when the surface of the electrode shell or the tube shell changes, the voltage should be quickly returned to zero, and then gradually increased from low voltage. If sparking occurs, it should stay at this voltage until there is no sparking phenomenon, and then raise the voltage again. The voltage rises to the specified value.

5.3 Install the air-cooled tube. The position of the air cooler must be consistent with the cooling wind direction so that the electrode core, tube element and other parts are well cooled. The connection between the air filter and the air blower must be soft and flexible (such as a flexible branch pipe or an insulated pipe, etc.) to avoid the sound being affected by vibration when the hair dryer is working. Install water cooling, paint cooling and evaporation When the anode tube is turned off, the escape and outlet pipes cannot be connected, and the cooling system is not allowed to tank water.
5.4 For the mobile complete machine, the installation should have anti-vibration measures. The power supply of the 55 electron tube is absolutely not allowed to be connected. The electrode and the power supply are not welded, but they should be in good contact, so as not to increase the mechanical force.
5.6 Before switching on the power supply of the electron tube, the following steps must be performed when the relevant cooling system voltage is turned on:
Turn on the light source:
Connect the grid voltage
Connect the anode light voltage:
d, connect the positive voltage (start from the electrode closest to the anode, and connect in sequence) e, and connect the electrodes of the same voltage.
When disconnecting the power supply of the electron tube, the corresponding steps should be performed or the electrodes should be disconnected at the same time. The power supply should be turned off for 5-1mn. The cooling system should be shut down. For electronic tubes with special requirements, the "Instructions" should be followed. 5. The voltage value of the filament after power on is the value of the filament lead-out part of the tube, excluding the lead wire. When the filament is powered on, it should be increased or stepped or the voltage should be increased too quickly to cause the filament to deform or break. For electronic tubes with a filament rated current of more than 4000, the filament current does not exceed E0% of the rated value. When the filament power is turned off, it can generally be turned off for the first time. For special requirements! The power supply of the tube lamp should be turned on and off according to its "instructions for use". During the period of tube operation, the filament voltage should be kept constant and the filament voltage should not fluctuate. Under the condition of ensuring the normal operation, the filament voltage should be kept constant and the filament voltage should not fluctuate. The positive polarity of the filament should be changed once every 2 hours of work to ensure that the entire filament voltage can be evenly distributed. The filament voltage should be reduced to a certain value of 23. The cooling system can be used. The good oxide tube should be used. During the working rest period, the emission is not.The filament voltage can be appropriately increased and re-excited (i.e. the filament voltage must be reduced by 15%~2% after the aging period). The power consumption of each electrode must not exceed the maximum rated value allowed by the specification, and the absolute maximum short-term efficiency is not allowed to be reached during the two short-term use. 5.9 It is also recommended to use it for the first time or in the next 2 months for aging treatment. The aging steps are as follows: a. Turn on the filament source: When the filament voltage is at the rated value, maintain it for 15-20min: b.
Switch on the grid bias and anode voltage, and the electrode voltage is the rated value; d.
Continue to maintain it for 15~20min. Then within 6~10min, gradually or in stages increase the anode voltage to a certain value, and then wait until the second anode voltage reaches the rated value:
SJ/T10316:92
[, Use for 1~2h under normal load: When the tube reaches the minimum voltage or when the plate core phenomenon occurs under full load, the disk will slightly reduce the pins of each pole, and after 5~.7nin, gradually or in stages increase the voltage to the rated value. For aging tubes with special requirements, they should be carried out according to the requirements of their "Instructions for Use" and used. For the electric tubes used in push-to-connect or parallel connection, the electric tubes with the closest voltage should be selected for use. 5.11 The user should keep detailed records of the inspection and use of the tubes, and should take the relevant data as quality feedback information.

The design of the cooling system water ridge should fully consider the water flow rate and water conductivity. The voltage of each tube (especially the anode) should have a high insulation value and the water flow should meet the requirements of the "Instructions for Use". There should be a positioning liquid in the anode water jacket to ensure that the water inside the anode is evenly spaced from the surroundings of the anode tube. The cooling system has a device to measure the temperature and flow of the cooling water, and the water inlet and outlet should also be equipped with anti-ionization electrodes. 6.3 Cooling of tea leaves The static operation of the electronic evaporator should meet the requirements of the "use instructions".

A small amount of machine maintenance method shall be used to eliminate the water (dirt) on the pole to avoid pressing the electron tube.
6. Day The refrigeration system should be inspected and tested regularly: blockage, air leakage, water leakage and overheating are not allowed. 6.9 The whole machine must have an interlocking device to ensure that the voltage is applied in a certain sequence and the protection against overcurrent and overheating should be provided. The voltage should be changed regularly to ensure fault detection and energy saving. 6.10 There must not be any conductor with too much current passing through the electron tube and parallel to the filament of the electron tube (i.e. parallel to the axis of the tube) around the electron tube. 10316—92
