Application and characteristics of ceramic plunger
Ceramic plunger is widely used in medical equipment, environmental engineering, petroleum, chemical and other industries, suitable for petroleum, chemical, machinery and other precision and corrosive substances more industries. The use of ceramic plungers instead of metal plungers in mechanical plunger applications can effectively solve the problem of poor corrosion resistance and low working temperature resistance of metal plungers.
Ceramic plunger products have high wear resistance, corrosion resistance and thermal shock resistance, and their service life is 10-20 times that of metal plungers. Oilfield application proves that the use of ceramic plunger can not only greatly improve the utilization rate of polymer in the original oil field. Take the technical transformation of metering pump plug as an example. When using metal materials, the injected polymer is highly corrosive, which can easily lead to lax sealing of the plunger and serious leakage, which affects the injection effect. Therefore, the plunger must be replaced every week, which not only affects production, but also causes great waste. After repeated tests by the technical personnel of the oil mine, the application of the ceramic plunger is successful, and the pump is turned on every day during normal production, which can save a lot of valuable funds every year and achieve good economic benefits.
The ceramic plunger adopts high-tech zirconia ceramic nanomaterials, which show the characteristics of high density, high hardness and never wear. Its ceramic hardness is HRY-80-90 Rockwell hardness, which is several times that of metal materials. In addition, the ceramic plunger also has a magical antibacterial effect, green environmental protection.
The high wear resistance of ceramic plungers is much higher than that of traditional metal plungers. It is an ideal substitute for metal plungers and greatly extends the service life of related parts. This is also related to its unique manufacturing process. The microporous structure of the working surface of the ceramic plunger obtained through a unique processing method has a self-lubricating effect, which changes the sliding friction and lubrication mechanism of the traditional plunger pump.
The inner cavity surface of the ceramic plunger adopts a fluid structure without dead corners and grooves; and the inner cavity surface is matched with the plunger surface, and is processed into a mirror surface by an advanced high-precision internal and external grinding machine, and the outer surface is vibrated and polished for easy cleaning and disinfection. Ceramic plunger has so many advantages, of course, can attract more users of all ages. Compared with the metal plunger, the ceramic plunger is not only more durable, but also has better use effect, which can meet the application requirements under some special working conditions.
Since the ceramic plunger is made of stainless steel and high-strength 99 porcelain, according to its use characteristics on the water jet loom and the characteristics of its local raw materials, the following points should be paid attention to during installation:
1. Ceramic plunger is a complete set of products. Because the fit clearance is small, the cleanliness between the plug and the sleeve must be guaranteed.
2. When screwing the ceramic plunger to the pump body, use thread sealant to tighten it.
3. Use special tools to prevent damage to ceramics due to uneven force during installation.
