The ceramic plunger and the spray ceramic are the main structural components of the car washing machine. Ceramic plunger is made of ceramic material, compact texture, small friction coefficient, with high wear resistance of the sealing parts; ceramic spraying is a surface treatment process that sprays ceramic beads onto metal surfaces to protect and strengthen them.

Advantages and disadvantages of ceramic plunger and ceramic spray

1. Advantages of ceramic plunger:

(1) The coefficient of friction is small, the friction heat is small, it is not easy to wear, and it has high sealing property;

(2) Good chemical stability, not easy to be corroded, can withstand high temperature;

(3) Ceramic materials have high strength, high hardness and are not easy to break.

2. Disadvantages of ceramic plunger:

(1) The cost is relatively high;

(2) fragile, use caution;

(3) The nature of the material is too unique, and the maintenance is difficult.

3. Advantages of ceramic spraying:

(1) The ceramic spray layer protects the damaged or corroded surface of the metal, improves wear resistance and corrosion resistance, and extends the service life;

(2) The cost of ceramic spraying is relatively low and widely used.

4. Disadvantages of ceramic spraying:

(1) can not be repaired, need to re-spray;

(2) The ceramic spraying layer is easy to fall off under extreme conditions.

Ceramic plungers have the following characteristics:

(1) Ceramic plunger using high-performance technology ceramic material, with high hardness, wear resistance, high temperature resistance, corrosion resistance and other properties. Ensure reliable material performance.

(2) The micro-porous structure obtained by the unique processing means of the ceramic plunger working face has a self-lubricating effect, which changes the sliding friction and lubrication mechanism of the traditional plunger pump.

(3) The surface of the inner cavity adopts a fluid structure, without dead corners and grooves. The surface of the inner cavity and the surface of the plunger are processed to the mirror by advanced high-precision internal and external cylindrical grinding machine, and the external surface is polished by vibration, which is convenient for cleaning and disinfection.

(4) The pump body structure is finely sealed with the product structure for easy disassembly.

(5) This kind of product has been corrosion resistance, acid and alkali resistance safety performance test, its indicators have reached the international advanced level.

The ceramic spray plunger is indeed better than the original metal plunger, because the surface is also ceramic, but there are several problems:

(1) Long time use, easy to cause the tank water, resulting in the crankcase oil into a white turbid liquid, increase the degree of friction, and then reduce the life of the whole pump.

(2) It can not bear large pressure, and the coating is easy to flake. After the coating falls off, the friction will increase, causing damage to the water seal and oil seal, and the problem of leakage and oil leakage will occur frequently.

(3) When damaged, it must be replaced as a whole, increasing the cost and difficulty of maintenance.

Methods for the use and maintenance of ceramic plungers and ceramic spray

1. Ceramic plunger:

(1) In the car washing machine using ceramic plungers, it should be noted that the ceramic plunger must not collide with other parts during the movement to avoid damage;

(2) The car washing machine with ceramic plunger should pay attention to insulation, and the ceramic plunger should not be in contact with the electrode.

2. ceramic spraying:

(1) When the car washing machine uses ceramic spraying treatment, it should ensure that the metal surface is clean and dry, without oil and sewage marks;

(2) After a long time of use, the wear of the ceramic spraying layer should be checked frequently, and if the wear is very serious, it needs to be replaced.

This paper introduces in detail the differences between ceramic plunger and ceramic spray in nature, use, maintenance, life and other aspects, which can help readers understand the advantages and disadvantages of the main structural components of these two car washing machines. In the purchase and use of car washing machine, it is recommended to choose the right product according to the actual demand and economic situation, while following the correct use and maintenance methods to extend the service life and ensure the use of results.
