If you want to buy a washing machine at home, you should pay attention to the maintenance work to avoid the malfunction of the washing machine and affect the use. If the washing machine malfunctions during use, it is necessary to find the cause and repair it in time. So what are the washing machine repair methods? How to maintain the washing machine? Let's take a closer look.
What are the washing machine repair methods?
1. The washing machine is not drained
(1) There may be debris in the drain valve blocking the undrained water. At this time, first open the drain valve cover to remove the debris;
(2) Check whether the adjusting rod nut on the drain valve is loose, and the tractor can not pull the drain valve core to cause undraining. At this time, fix the nut so that it can pull the drain valve core;
(3) It may also be that the computer board is damaged and the computer board should be replaced;
(4) The nut is not loose or the cable is not loose, the tractor may be damaged, the drain valve core cannot be opened, and the tractor should be replaced at this time;
2. Under normal conditions, the pulsator is running normally and reversely.
The water level switch contacts are always open. If the contact piece is rusted and the elastic pressure of the contact piece is broken, the contact can not be disconnected and the pulsator is running normally and in the normal state without water.
3. The washing machine is not only water
(1) The problem may be caused by the water level switch. When the usage time is long, the water level switch can stop the water inlet, causing the water to enter, and the water level switch should be replaced at this time;
(2) If everything is invalid, try to replace the computer board, because all actions are controlled by the computer board;
(3) The pressure pipe may wear out due to long wear and tear or the poor contact or disconnection between the pressure pipe and the water level switch and the outer drum nozzle may cause the water to enter, because the computer board does not move due to the pressure, the water level switch does not move. The misunderstanding is that the water level is not limited to water. At this time, the pressure pipe should be inspected for wear and no contact or disengagement at the joints;
(4) The valve plug of the inlet valve is stuck, and cannot be reset after the power is turned on, resulting in continuous water inlet. In this case, the inlet valve is replaced first;
(5) Due to the long use time, there is a foreign object blocking the mouth of the nozzle, so that the pressure cannot be transmitted to the pressure switch. At this time, the large nut should be unscrewed, and then the inner barrel should be taken out to remove the foreign matter blocking the nozzle.
How to maintain the washing machine?
In order to make the washing machine work normally for a long time, it is necessary to carry out correct lubrication maintenance on time. The main parts that need lubrication are the bearings and gears. The bearings need to be injected with oil-proof holes to prevent the abrasion resistance and oxidation stability. L-TSA22 Rust anti-oxidant lubricants, usually refueling once every 2-3 years. If you use general mechanical oil, you need to refuel once a year. The gears are made of 2nd extreme pressure lithium grease with good adhesion, or good oiliness, plus 1% by mass of zinc dialkyl dithiophosphate, or 3% by mass of MoS2, L-CKC100 Medium extreme pressure anti-wear gear oil for lubrication. The bearings and gears of the dryer should be added to the L-AN15 and L-AN68 lubricants with good anti-oxidation, anti-rust and anti-wear properties every year or half a year. For sealed rolling bearings, the bearing factory should be sealed with a polyurea-based thickened refined petroleum lubricating oil with a service life of more than 1000h, and a rust-proof antioxidant No. 2 grease.
Use the washing machine to pay attention to the maintenance and cleaning of the washing machine, which can also extend the life of the washing machine. The above is about the washing machine repair methods and how to maintain the washing machine, we have to go to the formal market to buy washing machines to ensure the quality of washing machines.
Fiber Optic Patch Panel(ODF)
Fiber optic patch panel is now widely used in networks and it is an integrated unit for fiber management, we are offering various kinds of Fiber Optic Patch Panel, such as wall mounted fiber optic patch panel, rack mounted fiber optic patch panels. These equipment functions to fix and manage the fiber optic cables inside the box as well as provide protection.
Our wall mounted fiber patch panels accommodate up to 8 modular panels and is equipped with routing guides to limit bend radius and enhance strain-relief control. The 16-gauge steel with corrosion-resistant black powder finish coat housing provides excellent protection for the inside fibers. Wall-mount available unloaded, as well as having the capability to become a full-splice enclosure with mechanical terminations. A large variety of connector adapters are offered to meet your specific requirements. Such as SC, FC, ST, LC, etc, we can also pre-install various kinds of fiber optic pigtails inside the patch panel.
YLTelecom offers a series of changeable inside panels to fit for different kinds of the adaptor interface, and fit for both round and ribbon fiber optic cables. Our rack mounted fiber patch panels can be drawer type or economic type without draw design.
A Fiber-Optic Patch Panel is used to separate out the fibers within a fiber-optic cable. By using one of these panels, the fibers can be spliced to individual fibers on other cables, allowing the cables to be crossed and connected in a variety of ways. In addition, the panel creates a safe environment in which to work with exposed fibers.
There are two main types of Fiber-Optic Enclosures. One is a wall-mounted device, which, in its most basic form, can keep 12 different fibers separate from one another. If the fiber-optic cable has more than 12 fibers, the extra fibers can be moved to a second panel or an engineer can use a panel that is designed to hold more fibers separately. Wall-mounted panels can be constructed to hold up to 144 fibers at once.
The other type of Fiber-Optic Patch Panel is a Rack-Mounted Panel. This type of panel holds the fibers horizontally and is often designed to open like a drawer. Sliding the panel open gives an optical engineer easy access to the fibers inside.
