Plumbing is a complex structure, the mainpart of which is exactly the mixer. Masters attribute to him the main purpose. This is to maintain the desired temperature and water pressure during operation. The crankshaft is a regulating and fixing mechanism. This element is the main pressure.
As a result, it is easy to understand that it is she who oftensubject to repair and replacement. Every person can do it himself, because there is nothing difficult in the work. The modern water supply system has two main types of structures - worm and ceramic.
Worm gear
Crane box received this name from the existingmechanism. The shaft of a rotary rod is taken as a basis. Outside there is a thread and a working space with a wrench. Inside there can be two options - with a reverse worm shaft thread or a guide for a check valve. If this is the first option, the rotation is relative to the mixer.
The locking gasket should lock tofixed valve, although often this is done directly to the stem. There must be a thread on the outside to mount with a bolt. If a worm gear rod is used, it is mounted with a bracket. Water leaks are excluded, as the seal is installed.
Operation process
The worm construction of the crankshaft is known onover several years and is actively used. To understand that the design was created many years ago, you should pay attention to the head. It should be square. Today produce spline. Masters believe that the shelf life depends on two main factors:
- Abrasion gasket. But if it is good to grind the saddle, the period of use increases.
- The seal is adversely affected by compounds in the water, which leads to wear.
An omentum can also often fail.The reasons are the same as for the gasket. However, if lubrication occurs in time, breakdowns rarely occur. We also note that the crane-box of the worm design does not have such a long service life as other types. But at the same time its price is low. Yes, and repair crane axle box to make easy.
Есть одна особенность.If the crane is used in the kitchen or in the bathroom, where there is a high level of intensity of use, then its term is no more than two years. But on the riser this period increases to five. Moving parts are subject to wear.
Ceramic
These types of faucet sleeves are prettymodern. At the base - two plates of ceramics. They are tightly fixed to each other, but have holes for the flow of water. One is motionless, and the other changes its position in order to be combined with the recess and to carry out water supply. Ceramic crankshaft jumper is threaded to fit with mixers. Butt parts are protected by seals, which avoids leakage.
With the help of a washer, the rod is fixed to the body.For sealing there is an oil seal. After the adapter is applied. Its choice depends on the model. The slot connection allows you to securely fix the fixed ceramic disk to the bolt. Already further it is necessary to complete the construction with a gasket to avoid leakage.
There are many advantages of a ceramic crankcase, especially when compared with the first model.
How does it work
Since the design is fully thought out, thenthe result is a tight locking mechanism. Ceramics are not subjected to chemical composition of water, and therefore, serves a long period of time. Masters call the period of operation at least five years. Despite many advantages, this design has its weaknesses. Sand particles in water adversely affect ceramic discs. But you can cope with this by installing additional filters, although it is not appropriate to create such conditions in every place.
What are the dimensions of the crankshaft? Diameter - from 10.8 to 24.5 mm. Length - from 24 to 42 millimeters. What are the crankshaft dimensions of the thread? It is metric, in 1, 2 or 2.5 mm increments.
What you need to know about the repair?
There are new discs on sale, but there is one caveat:fit them as closely as possible will not work. Yes, and will have to change all the nodes. Only the factory crane will last a long time. After repair, its operation period is halved. Leaking seals on the stock rarely occur, one might say, never. Because there is maximum sealing and good lubrication.
Crane replacement
How to change the crankshaft if presentleakage? Oddly enough, it is done by those who have no experience. The problem can only appear in the correct selection of spare parts for your crane. It is better to remove it and go to the store to search for identical designs. Do not forget that the water is pre-overlapped. What steps do:
- Of the tools worth preparing: a screwdriver, adjustable wrench and bran, pliers and a knife.
- Shut off the water.
- The design has a decorative cap.It may simply be worn or bolted. Depending on this, either a screwdriver is used, or simply the part is removed with a knife (but neatly, so as not to break anything).
- Further it is necessary to dismantle the fixing screw.
- It is necessary to remove the valve, but so that the grooves are not broken. Next, the valve is unscrewed.
- After it is time decorative trim.This is done with pliers or a screwdriver, but they need to be softened beforehand. For this fit insulating tape or any inserted material. This method completely eliminates the appearance of scratches that will not lead to additional damage.
- The crankshaft is dismantled with a screwdriver.key. After the design is opened, you can see the joints, which are covered with rust, It is necessary to clean them. A simple vinegar is suitable for this. It is poured and then dismantled.
- Когда кран оказался на своем месте, не стоит его strongly tighten so as not to tear the threads and damage the gasket. There is a simple way - they twist their hands to the full stop, but into a packed ring. Next, using the tool rotates 90 degrees. That will be quite enough.
To cope with the replacement can each. It remains only to acquire the necessary and stock up on the tool. The stores sell faucet boxes for mixers, the types of which are very different.
How to avoid breakage?
Often you need to understand when going with a tapThere is something wrong with the breakdown not occurring. When there is a grinding sound after the water supply or pressure is intermittent, this already indicates a malfunction. If a valve leaks, sometimes the gasket just changes.
Remove the crane-axle box, then you need to turnattention to the water intake saddle. If any chips or other malfunctions are found on it, you will have to completely change it, as the repair will not bring results. Gasket purchased in the store, although many do it themselves. Then it is attached to the screw or rod.
Conclusion
So, we figured out how to repair the crankshaft. As you can see, this is a simple process - you only need to carefully follow the recommendations.
