※ Is the life of the conductive slip ring long?
Many customers are concerned about how the service life of the conductive slip ring is, and whether the service life of the conductive slip ring is long. In fact, the life of the conductive slip ring depends on many factors, which can be roughly divided into two categories. One is the service life of the material used for the slip ring itself, and the conductive slip ring is actually a semi-consumable part. The second type is the external use environment of the slip ring, and the external use environment of the slip ring has a great influence on the service life of the conductive slip ring.
Let's first talk about how the material of the slip ring itself affects the service life of the slip ring. Our company will design the service life of the slip ring according to the customer's usage. Among them, our biggest basis is the rotational speed of the customer's equipment. The rotational speed of the customer's equipment is within 200 rpm, and the designed service life of our slip ring is 20 million- 30 million rpm, the speed of customer equipment is higher than 200 rpm and less than 1000 rpm, the design life of our slip ring is 50 million-100 million rpm, the speed of customer equipment is more than 1000 rpm and less than 5000 rpm, Then the design life of our slip ring is about 500 million revolutions.
Many customers will be very concerned about the service life of our design. Today, Xiaobian will explain to you in simple words. The design service life of the slip ring is based on the contact material inside the slip ring. The speed below 200 is called a general-purpose slip ring in our industry. The contact material inside the slip ring is generally directly plated with copper alloy tin or silver. This material can ensure the normal transmission of current and signals, but its wear resistance is lacking. We call it an industrial-grade conductive slip ring with a speed of 200. This slip ring is made of precious metal gold-plated material as the contact material. Many customers will ask what kind of precious metal this is. I can only tell you with regret, This belongs to the company's secret, and I can't tell you. For the slip ring with a speed of more than 1000 rpm, we call it a military-grade bottom slip ring. We use gold alloy as the internal contact material for this type of slip ring, which fully guarantees its wear resistance and excellent performance. Conductivity.
The above-mentioned is the internal design service life of the slip ring. The service life of the slip ring is not only determined by its internal material, but the external use environment has a greater impact on the service life of the slip ring. The high temperature and high humidity outside the slip ring , dust, acid gas, alkaline gas and a series of environmental factors can affect the service life of the slip ring, so we will ask the customer about the use environment when customizing the slip ring, and then we will go according to the use environment. Targeted solutions, so there are a series of conductive slip rings developed and designed for the use environment, such as explosion-proof slip rings, high temperature resistant conductive slip rings, and waterproof slip rings.
※ Why is the service life of the mercury slip ring not long?
Why do mercury slip rings have a long service life? This is a question that many clients often ask me. In fact, this is related to the use environment of mercury slip rings, because mercury slip rings are mostly used on electroplating equipment, and the ambient air temperature of electroplating equipment is relatively high. Mercury, as a volatile liquid metal, is very volatile at room temperature. Electroplating The high temperature environment of the equipment further accelerates the volatilization rate of mercury inside the mercury slip ring, and the increase of the mercury volatilization rate directly affects the service life of the mercury slip ring.
In order to prolong the service life of the mercury slip ring, the sealing problem of the mercury slip ring must be solved. In addition, the material of the mercury slip ring shell must be a corrosion-resistant material, so as to ensure the service life of the mercury slip ring. The service life of the mercury slip ring can be guaranteed only if the corrosion-resistant material is used as the shell of the mercury slip ring and the sealing performance of the mercury slip ring is solved at the same time.
The water slide adopts high-quality 304 stainless steel as the shell of the mercury slip ring, and at the same time adopts the imported sealing ring to solve the sealing problem for the mercury slip ring. At the same time, with its precise machining, all these favorable conditions ensure that the service life of the produced mercury slip rings is much higher than that of similar products in the same industry.
