How to reduce the incidence of rapid temperature change test chamber failure
The rapid temperature change test chamber belongs to a very high value equipment. As the use time of the equipment increases day by day, there will be some minor faults. However, some small faults are not problems in the machine itself, but it is caused by improper operation or maintenance. The "hidden danger" buried in the ground, which requires us to master the standard use method and scientific maintenance knowledge, in order to reduce the failure rate of equipment.
Be careful not to let dust, thread, iron filings or other things enter during machine installation, otherwise malfunction or malfunction will occur.
To prevent electric shock or malfunction and malfunction, do not turn on the power before installation and wiring are completed. To avoid machine failure, supply power within the rated voltage range.
Wiring must be correct and must be grounded. Failure to ground may result in electric shock, malfunction, abnormal display, or large errors in measurement.
Check the terminal screws and the holder regularly, and do not use them in a loose condition.
This product is not explosion-proof, please do not use it in the environment of flammable or explosive gas.
Do not use the machine if it is found to be damaged or deformed when unpacking.
Please try not to open the test box door during the operation of the instrument. If it is opened at high temperature, it may cause burns to the operator. If it is opened at low temperature, it may cause frost damage to the staff in the morning.
During the experiment, the switch box has certain damage to the compressor. Unless the test requires, the customer is not recommended to open and close the door during the experiment.
The vents of the body should be kept open to avoid malfunctions, abnormal movements, reduced life and fire.
The power input terminal cover must be installed on the terminal block to prevent electric shock during operation of the instrument.
Before the instrument is in operation, the safety should be fully considered before the operation of modifying the setting, signal output, starting, stopping, etc., and the wrong operation may cause damage or malfunction of the working equipment.
Wipe the meter with a dry cloth. Do not use alcohol, benzine or other organic solvents. Do not splash water on the meter. If the meter is immersed in water, stop using it immediately, otherwise there is danger of electric leakage, electric shock or fire.
The internal parts of the instrument have a certain life span. For continuous and safe use of the instrument, please perform regular maintenance and maintenance. When disposing of this product, please dispose of it according to industrial waste.
Non-operator personnel are not allowed to repair and inspect the machine. In addition to the full-time staff, there is also a professional electrician and circuit inspection staff to prevent uninformed staff from being energized and closed. Risk of electric shock.
The support grid is made of several Johnson screen sieve plates. Specification and size is customized. Material: 304, 321, 316 L, 904 L, duplex steel 2205, duplex steel 2207, Monel, Ti.etc.
Due to the good mechanical strength, it effectively prevents its own damage and tear in contact with the filler (quartz sand or porcelain ball, etc.) and catalyst ensuring the safe and smooth operation of the reactor in a long period. Therefore, it has gradually replaced the traditional stainless steel woven mesh and perforated plate tray, and has been widely used in petrochemical field.
