The development of new technologies has a significant impact on increasing the level of comfort. This applies to almost all areas, from the automotive industry to the necessary household appliances. The latter include such as a ceramic bushing faucet, which can increasingly be found in the standard equipment of mixers.
Design
Despite the external resemblance to standard worm designs, the axle box crane has a fundamentally different structure. Traditionally, the water pressure is blocked by gradually lowering the stem when the faucet is turned. Or a ball with a hole is installed, connected to the control handle - by changing the position of the structure, they reduce or increase the water pressure. Such methods are characterized by low reliability and the likelihood of leaks.
The faucet with ceramic faucets has no such disadvantages. Thanks to a carefully thought-out design, with a minimum of effort, you can achieve precise adjustment of the water pressure. In order to understand the principle of action, it is necessary to know from whatalso consists of a crane box.
- Case. Its surface serves as a mounting element for installing the structure in the container of a tap or mixer.
- Lever. It is connected to the control parts of the box, and its outer part is needed to install the handle.
- The locking and regulating element consists of 2 ceramic-metal plates interconnected. On the body of each of them there are holes, the position of which relative to each other is adjusted using a lever.
With a minimum of moving parts and their reliability, smooth regulation of the water flow is ensured.
Working principle
Ceramic bushing crane operates on the principle of changing the passage hole between the plates. After installing the block in the mixer, water under pressure enters the structure body. The normal position of the plates is such that the holes on them do not coincide with each other. Thanks to a perfectly flat surface, a tight pressure is applied to ensure tightness.
Further, as the lever is turned, the planes are shifted, as a result of which the holes of the plates overlap. The water in the body, under its own pressure, passes into the gander of the crane. The basis of the reliability of the operation of the device is its simplicity. It is this design that replaces the worm and ball models.
Advantages and disadvantages
Like any complex structure, a ceramic bushing for a crane has a number of distinctive performance properties. They also appear ininstallation process - for the correct operation of the device, you only need to screw the block into the faucet body.
The positive aspects include the following:
- Low effort to open (close) the faucet.
- Small overall dimensions that contribute to the reduction of plumbing fixtures.
- Reliability. Subject to the operating conditions, a ceramic axle box crane can last for decades.
But besides this, there are disadvantages to consider:
- High cost compared to classic locking devices. The exceptions are cheap models, which have significantly reduced the quality of the materials used.
- Water requirements. In the presence of solid particles, the ceramic plates will wear out quickly, which is caused by an abrasive reaction - damage to the surface, as a result of which the tightness of the device will deteriorate.
All this must be taken into account when choosing a particular model of ceramic bushings. But sooner or later, even this reliable device can fail.
Repair
Due to the simplicity of the design, it is possible to repair a ceramic crane box on your own. To do this, you will need a screwdriver, pliers, WD-40 spray (or equivalent) and a replacement gasket. The latter is best selected using the old one as a sample. Most often, it is she who is the source of the leakage in the tap.
Orderrepairs:
- Dismantling the device from the faucet body.
- Use a slotted screwdriver to remove the retaining ring from the lever.
- Next, the plates and control element are removed.
- After that, the metal surface is treated with WD-40. This is necessary to remove the rust layer.
- Then the device is assembled again, a new gasket is installed on the end. This completes the repair.
If damage to the plates is visible during inspection, then the ceramic bushing needs to be replaced. It is difficult to find and pick up similar components. Fortunately, the cost of good factory models is more than affordable.
