Precision machined ceramic plunger
1. indexing plunger
The front of the pin of the indexing plunger is a slope indexing plunger, which can roll and release the force according to the slope orientation to avoid backflow.
Screw the indexing plunger into the bottom plate completely during use, please round the wire hole on the side of the bottom plate.
The pin can be turned by screwing the knob, and the angle of view can be changed every 60 degrees. Depending on the viewing angle, tighten the square anchor bolt fixing pin.
2. indexing plunger (pneumatic type)
The indexing plunger (pneumatic type) is an indexing plunger operated by providing standard air pressure to urge the pin projectile to come out. Disconnecting the standard air pressure will retract the pin to the internal structure by the elastic force of the embedded spring.
Ceramic plunger and spray porcelain plunger, which is better or worse?
High-pressure plunger pump is a key component of high-pressure cleaning machine, and the plunger is a key component that is easily damaged in the watch movement, and its quality is directly related to the performance of the entire equipment.
According to the plunger material is not the same to classify, plunger can be summarized as metal material plunger, ceramic plunger, spray porcelain plunger these three. At present, the plunger used in the high-end equipment on the market is usually two types of ceramic plunger and porcelain plunger. The world's famous high-quality pumps, drive shaft pumps have adopted ceramic plungers.
They are the originator of the plunger centrifugal pump, after years of practical activities, the main performance of the ceramic plunger plunger pump is more outstanding. At this stage, all European high-end high-pressure pump manufacturers have adopted ceramic plungers, and none of them have adopted ceramic plunger. Thus, in general, the quality of centrifugal pumps with ceramic plungers is significantly better than that of ceramic plungers.
And now in the Chinese market is still a popular saying, spray porcelain plunger is a new upgrade of ceramic plunger, spray porcelain plunger is stronger than ceramic plunger. Then let's take a closer and objective look at the comparison of the two commodities.
zirconia ceramic
What kind of CNC machine tools can be used to process zirconia ceramic parts
Ceramic plunger has the following characteristics:
(1) Ceramic plunger adopts excellent performance technical structural ceramics, with high hardness, wear resistance, heat resistance, corrosion resistance and other characteristics. Ensure material properties are reliable.
(2) The fine hole mechanism obtained by using the different processing method of the ceramic plunger work surface has the effect of self-lubricating bearing, which affects the principle of rolling friction and smoothness of the traditional plunger pump.
(3) The inner wall surface adopts liquid structure, and there is no dead angle and pipe trench in all directions. The surface of the inner wall and the surface of the plunger are matched with each other, and the mirror glass is produced and processed by a cutting-edge high-precision inner and outer cylindrical grinder. The outer surface is vibrated and polished for convenient cleaning, disinfection and sterilization.
(4) The pump casing structure adopts meticulous sealing with the product structure, which is convenient for disassembly and assembly.
(5) this kind of products have been tested for corrosion resistance and ph resistance, and their various performance indicators have exceeded the world's excellent level. The porcelain plunger is really better than the original metal plunger, because the surface is porcelain, but there are also many related problems:
(1) long-term use, easy to cause the oil tank water, resulting in crankcase ventilation oil into a pure white turbid liquid, enhance the degree of friction, thereby reducing the service life of the whole centrifugal pump.
(2) can not bear relatively large working pressure, the coating is very easy to fall off. After the coating falls off, the friction is raised, which promotes the destruction of the exhaust valve skeleton seal, etc., and the problem of water seepage and oil seepage occurs frequently.
(3) When it is destroyed, it should be replaced in general, and the maintenance cost and difficulty coefficient should be increased.
