Recently, the cold wave struck and there was heavy snowfall in the middle and lower reaches of the Yangtze River. From the 20th to the 23rd, affected by the eastward movement of cold air over the south and the warm and humid southern part of the Yangtze River, most parts of Jianghan, central and southern Jianghuai, northern and central Jiangnan, Blizzard has big, big blizzard (daily snow 20 to 30 mm). Strong cold air strikes affect the central and eastern regions, and there will be a strong wind and strong cooling course in the central and eastern parts of China from north to south. Hangzhou extreme low temperatures may be close to or breaking the historical low value, think people are shivering it!
It's so cold tripod turnstile What should it do?
Check tripod turnstile Movement: tripod turnstile Maintenance of the movement is the core of the entire machine maintenance, the rotation of the machine by the movement, the movement in the long hours of work also need maintenance, usually once a month minor maintenance, according to the number of work, in general Work 6-10 million times a small maintenance time, six months a major maintenance time, 30 to 600,000 times a major maintenance, maintenance professional maintenance master operation, first cut off the power, clean the dust above, be careful not to damage the original circuit, check the damping rubber Is the wear and tear, whether to change or replace, the surface clean, fasten the connectors, the positioning arm surface butter, check other wearing parts, such as positioning arm, where the gap is greater than 2mm to be replaced, the general damping Glue is not easy to wear. Check the gate valve. Solenoid valve magnetic force is not enough, not enough to see the output voltage is there 24V, less than 20V circuit problems, suction enough. The same as the bar magnet, but also 24V, not enough to check the circuit. Do not add oil or butter inside the solenoid valve, which clean up on it, can not have dust, dust valve body and the valve can not be fully integrated, resulting in insufficient suction, organic oil or butter, valve body and body generated James, can also lead to insufficient suction.
Electronic control and maintenance: In front of the solenoid valve voltage 24V, did not see if the plug is loose. There is no wrong place, the wrong position will lead to voltage not enough, only 17V, RS Security Co., Ltd in the maintenance of customers have encountered a similar problem, check the insurance is not intact, the signal is not light, The direction indicator is not in accordance with the provisions of access instructions, the input voltage has not reached 220V, transformer work is normal, the transformer output has two voltage, all the way to 24V, the other way 12V, the aging degree of the line. Need to replace the firm replacement, without leaving trouble. Resolutely put an end to take the power on the motherboard, there are individual customers at any time in order to facilitate gate voltage gate, so unreasonable or unscientific, at any time on the access control and gate danger of burning.
3. Chassis air circulation or heater, in the northern city, the weather is cold, the conditions inside the machine plus a small fan, which helps the air circulation inside the chassis, not prone to water droplets, check the electronic control waterproof box is sealed, tripod turnstile Electronic control generally have a waterproof box, the purpose is to improve the service life, so as not to drop into the control panel directly. Arctic weather in the north, below minus 30 °, the machine is difficult to work properly, need heating, heating temperature can be adjusted to ensure that there is a certain temperature inside the chassis to work properly,
Reduce or isolate the moisture, haze days are also more, the air is humid, the need for human intervention to protect the machine, under the machine (from the ground), covered with waterproof plastic tape, separated from the ground to return the moisture, many machines under the air , You need artificial assistance, moisture generally come in from below, under the conditions to play sealant, so to reduce the source of moisture, and then the lid or door plus black tape, seal it is also beneficial.
Chassis maintenance measures: tripod turnstile machine generally made of tempered material, long-term exposure, the surface is inevitable rust spots such as macular, so need to clean up, the general appearance of a day to clean, with a soft cloth and fossil powder to polish the chassis, painted Rust-proof oil, rust-proof oil just painted do not rub it by hand, wait 3 to 5 hours of natural drying can touch, outdoor tripod turnstile encountered rainy days, it is best not to use, cut off the power, thunder and strong current will hit Wearing bad motherboards and access control panels to prevent leakage, water leakage will have occurred, the rain stopped first dry the chassis, check the circuit and then work, scratches the surface of the indoor tripod turnstile, find a professional repair chef repair, along the lines of the machine itself Care, texture is consistent nice.
