Longevity requires maintenance daily use and maintenance skills of projection
The birth of the projector has brought considerable convenience to users in business, education, education and other industries. However, while enjoying the large screen of the projector, do users pay attention to the daily use and maintenance of the projector? According to the user Different ways and habits of using the projector, the service life of the projector will also be shortened accordingly, so users must regularly maintain the projector to ensure a longer service life of the projector.
The usual ways of using the projector are divided into: desktop direct projection use, ceiling hanging use, portable take-out use, the three projectors will use different maintenance methods with different characteristics.
1. Please pay attention to the connection of the projector used in the conference room desktop direct projection, to avoid accidental shutdown caused by accidentally touching the power supply. When the projected picture is tilted or deformed, you can adjust the legs of the machine and fix the position to make the picture normal; when the machine is working, do not block the vents and affect the heat dissipation of the machine.
2. At present, the projectors basically have the function of inverting the screen, this function makes the projector can be used on the top of the house. For ceiling projectors used in indoor ceiling installations, special attention should be paid to the following points: the distance between the projector and the screen (determined by the screen size) is appropriate; the upper edge of the screen hanging on the wall should be the same as the lens of the ceiling projector On the same horizontal line; the center point of the projector lens and the center point of the projection screen are on the same vertical line; select the appropriate size of the installation hanger; the screws and bolts for installation and fixation are tightened in place; adjust the trapezoid of the projection screen after installation; after each use , Make sure to turn off the power.
3. A projector that is often used for carrying out. The machine is often moved and connected to different input devices. In this case, the following points need to be noted: When moving the projector at a distance, be sure to pay attention to the packaging of the machine. When shipping and shipping the projector, try to use original shock-proof carton packaging; users can be equipped with a hard packaging box; when you carry it, you can put the projector in a soft backpack; be sure to take it gently when moving the projector Handle gently to avoid lens damage due to shocks. During mobile use, pay attention to the impact that the power supply and different input device performance may have on the projector. If you need the projector to be moved frequently, then when you buy, you should consider buying a compact product with a dedicated carrying case.
In order to ensure the normal operation of the projector, regular inspection and maintenance are essential. For example, cleaning the ventilation screening program, the projector's cabinet generally has slots or openings, this is used for projector ventilation design, the air inlet has an air screening program, when the projector is working, it is used to filter dust And pollutants, after using for a long time, dust will accumulate in the slot of the screening program. In order to ensure the normal operation of the machine, it is necessary to periodically suck the suction opening with a vacuum cleaner. When the machine is working, do not block the ventilation fan with objects. The cleaning and ventilation screening program is especially important for the maintenance of the projector used for ceiling installation. Special attention should be paid to dust prevention during engineering installation and subsequent user use.
The most common problem with home projectors is that the power is turned off improperly. When the power off button is pressed, the projector fan will run for a period of time, and the fan will be turned off and turned off only after the temperature in the machine drops to a safe level. The main power supply can be turned off. When replacing the projector lamp, wear gloves to replace it. If oil gets on the lamp, it may affect the life of the lamp.
If the user finds that the projector cannot be turned on, the user must not disassemble the machine by himself (to avoid unnecessary trouble), and a professional projector maintenance staff should be asked for inspection and maintenance.
Belt conveyor, also known as belt conveyor, is a kind of continuous transportation machinery, but also a kind of general machinery. Belt conveyor is widely used in ports, power plants, iron and steel enterprises, cement, grain and light industry production lines. That is to say, bulk materials can be transported, or items can be transported. The noise is small and the structure is simple. Belt conveyor can be used for horizontal or inclined transportation. The belt conveyor is also applied to continuous transportation mobile machines such as loaders, unloaders, stackers and reclaimers. The belt conveyor is composed of belt, frame, driving roller, steering roller, bearing spoke, return roller, tensioning device, cleaner and other parts. In large ports or metallurgical enterprises, belt conveyor is widely used. Its total length can reach more than ten kilometers.
