1,After the test is completed, clean the dirt on the surface of the equipment with clean water, wipe it with a clean towel, and put it back in place according to the packaging requirements; Do not allow the device to be squeezed, bumped or impacted, which may cause unnecessary damage.
2, the bathroom should be left under the ceiling vent. When left on the ceiling, it is necessary to use a hand lamp to check whether it has installation, and use the method to measure the pumping force. Use a flashlight to check whether there is construction waste in the flue and vent. The bathroom with Windows in the corridor should be installed with anti-theft nets. If there are no Windows, there should be ventilation holes, and the ventilation holes should be located under the ceiling.
3, if the pressure test found pressureIf the force is not enough, then you can pump water in stages, and use this method to check if there is any leakage in the water pipe. (2) Water pipeline laying to ensure that the line is horizontal and vertical, such a line is conducive to later reinstall the water transformation.
4, look to see that the disadvantages of walking on the top are more than walking on the ground. In fact, when making water pipes, we should also pay attention to these points: the direction of the water pipe should be previously planned, and try to avoid unnecessary joints, because the joints are more hidden dangers. PPR pipe should not be excessive when hot melting, and the diameter is small to affect the water. If it is a large villa, the water inlet pipe is better than the diameter of the conventional pipe.
1, What is wireless fire hydrant water pressure monitoring? : Real-time monitoring of fire hydrant medium pressure, medium temperature, ambient temperature and Beidou /GPS information. What is the use of wireless fire hydrant water pressure monitoring? : The pressure of the water in the fire hydrant, if the pressure is reduced and other information can be monitored in real time. The function of the fire hydrant is mainly that the fire truck draws water from the municipal water supply network or the outdoor fire water supply network to extinguishment the fire, and it can also be directly connected to the water hose and water gun.
2, Yes. Fire hydrant water pressure monitoring can find the change of water pressure in fire fighting facilities in time, which can be used for fire fightingWork to provide timely and accurate data support, improve the efficiency and accuracy of fire work. The hydrant water pressure monitoring system uses advanced Internet of Things technology to monitor water pressure and other data in real time.
3, this product uses high-precision and high-stability isolation film diffused silicon pressure sensor for the collector pressure sensor chip, with high-precision AD microprocessor, through the wireless communication module to transmit data, wireless monitoring. The product comes with LCD LCD display and power button, which can realize data display, record and save, and real-time alarm of abnormal pressure. It is mainly used in places with fire pipes and fire hydrants for convenienceThe field observes pressure at any time.
4, used to monitor fire water pressure, high water tank level, through NB, LORA or access to the fire host, to achieve online monitoring of fire water source information. Smoke detector Smoke detector since its birth, has gone through more than a hundred years of history.
According to the "Mandatory certification Management Provisions", all goods listed in the 3C certification catalog must be certified and added to the China mandatory certification mark, otherwise they may not be exported, imported or sold.
Ten agricultural machinery products: including plant protection machinery. Ten latex products: including rubber condoms. Medical equipment products: including medical X-ray diagnostic equipment, hemodialysis devices, hollow fiber dialyzers, extracorporeal circulation tubes for blood purification devices, electrocardiogram machines, implantable pacemakers, artificial heart-lung machines. Fire products: including fire alarm equipment, fire hose, sprinkler equipment.
Among them, the power supply (0800907) has been in the 3C certification catalog before, and this is listed as "newly included products", and the operations are as follows: According to the description and definition of the Mandatory Product Certification CatalogThe scope of application of power supplies for Category 55 of the Table (Revised in 2020) includes audio and video equipment, information technology equipment and computer/server built-in power supplies.
After the update of the CCC certification catalog, some products are no longer mandatory for CCC verification, and enterprises can choose to confirm compliance with regulations by themselves. In the 2018CNCA announcement, the latest version of the 3C certification product list is listed, covering cable lines, mining cables, railway vehicle cables, rubber and polyethylene insulated cables, power switches, optical fiber couplers, industrial sockets, hot melt adhesive, circuit breakers and many other products.
There are regulations in the service area, we must provide boiled water for customers. As an important part of networked toll roads and supporting service facilities, the service area should be synchronously planned, designed, constructed and put into use with the main project of networked toll roads.
In the internal regulations, to provide free boiling water. Therefore, if you find that there is no, you can call the highway company, the transportation bureau, the transportation department, etc., to report and complain.
ServiceDistricts shall ensure the provision of boiling water services. If this service is not provided, consumers can report and complain to the highway operator, the transportation bureau or the Department of Transport by telephone.
There is free hot water in this service area. Many motorway service areas provide free hot water, which is convenient for passengers to boil water to make tea or instant noodles during the journey. Hot water supply points can be found in the public area of the service area or in the restaurant, usually a water heater or faucet, which can be operated according to the above tips.
Hot food is not allowed in the service area on the highway, generally only boiling water is provided. clothingService areas, also known as rest stops, appear on highways and other occasions, and are mainly used for short breaks and to provide services, such as toilets, gas stations, grocery stores and other services. In the service area, there are usually gas, shopping, and even accommodation facilities.
