NEW RYCO Product Technical Manual
NEW RYCO Product Technical Manual

RYCO have pre-released our Product Technical Manual (PTM) in soft copy for 2019. The new look technical manual for hose, couplings and adaptors has been developed to cover all markets RYCO services around the world. With the addition of new hose and coupling products, our new Product Technical Manual is the most comprehensive we have released. Notable changes in the Product Technical Manual are the introduction of dimensional tables for Back Up Hex (AF), Male Hex (HM) and Female Hex (HF) being published. These dimensions are published in imperial and metric on a selected range of coupling series, and can be clearly identified with imperial in black text and metric in blue text. An illustration of the new coupling tables can be view on page 31 of the Product Technical Manual. Hard copies of the Product Technical Manual will be available in early 2019.

System Cleanliness - Ratings & Filtration
System Cleanliness – Ratings & Filtration

In order to monitor and quantify the cleanliness of the fluid in an hydraulic system, standard rating systems have been developed over the years. These cleanliness ratings also allow us to measure the effectiveness of any filtration systems put in place to maintain the cleanliness of an hydraulic system. Cleanliness Rating Systems The cleanliness of a fluid can be measuring using a number of different standard classification systems, as outlined below. ISO 4406 ISO 4406 describes a method by which to count and record particle sizes. An average is taken by counting three size ranges. Particles greater than 4 microns. Particles greater than 6 microns. Particles greater than 14 microns. Because the number of particles within a system may be very high, the actual number is not used. Instead, a number is used to represent the value. This "class" number is based on the following table. The table below is the ISO 4406 codes. There has been two major editions of this standard, 1987 and 1999. 1999 is the current edition, and it should be used when possible. ISO 4406: ...

System Cleanliness - Contamination & Analysis
System Cleanliness – Contamination & Analysis

The performance of hydraulic systems can be impacted by the presence of contaminants in the hydraulic fluid. But how does contamination arise, and how can we monitor and quantify it so that we can effectively manage it and minimise any potential damage to an hydraulic system? An overview of contamination Definition in fluid power Any material, foreign to a system's fluid that has the potential to damage components within that system. Contaminants can be solids, liquids or gasses. What is contamination? There are 7 different classes of contamination: Abrasion - Hard particles causing wear Fatigue - A repeated stressing on a surface Erosion - Particles striking at high velocity Corrosion - Chemical degradation Adhesion - Particles sticking to a surface Cavitation - A vacuum being induced on a fluid Aeration - Gas bubbles within a fluid What causes contamination? There are 3 main causes of contamination: Manufacturing Contaminants can be built-in to a system during manufacture. Hoses, tubes and other components are dirty when fitted Ingress Contaminants may ingress into a system. They may gain entry through seals or tank ...

Using the Impulse Curve in Hydraulic Hose Assembly Testing
Using the Impulse Curve in Hydraulic Hose Assembly Testing

When conducting standard testing procedures on hose assemblies, the cycles of applied pressure create an impulse curve. The shape of this impulse curve is strictly controlled to ensure standardised, consistent test results. The rapid rise and fall of the pressure increase and decrease cycles must fall within the shaded limits. This happens at between 30 and 70 cycles per minute, with 60 cycles per minute being a typical frequency. This means that it only takes only one second for one impulse cycle. Example impulse test configurations For example, RYCO T3K4D: SAEIOOR17, 1/4" one wire braid hose with a maximum working pressure of 210 Bar (3,050 PSI) and maximum working temperature of +1000C would be tested as follows: Maximum Impulse Pressure: 210 Bar x 133% = 280 Bar (4,060 psi) Temperature: + 1000C Minimum Bend Radius: 50mm in 1800 arc Number of Impulse Cycles: 200,000   Four 'unaged', or new, hose assemblies must be tested, and all four must pass the impulse test. If any one assembly fails, the test is failed. It is a tough test. The rapid pressure increase ...

Impulse Testing of Hydraulic Hose Assemblies
Impulse Testing of Hydraulic Hose Assemblies

The aim of any hydraulic hose coupling must be to grip the hose for the lifetime of the assembly, never leak or weep and never blow off the hose. The ultimate test for an hydraulic assembly is always "on the job", as this proves whether the hose and couplings can meet the demands of the application. Proving hydraulic hose designs But have you ever wondered how hydraulic hose coupling manufacturers prove their designs before releasing them for sale to the market? There are applications that combine working conditions of pressure, temperature, flexing, aging and mechanical loads the designers could never have thought of. Think of hydraulic hammers as they pound into rocks, tree harvesting machines as they lift and tilt huge tree trunks, ground engaging tools on backhoes suddenly hitting a rock or root hydrostatic transmissions suddenly being thrown into reverse gear while travelling forward. All these applications and many more put great stresses on hydraulic hose assemblies. It's not possible to design laboratory tests to simulate all the possible combinations of conditions that a hose coupling may encounter during ...

Understanding Filtration - Fluid Cleanliness & Filter Efficiency
Understanding Filtration – Fluid Cleanliness & Filter Efficiency

In part 1 of this series on Understanding Filtration - Viscosity and Temperature we covered the significant impact that temperature has on the viscosity of an oil, which in turn affects its performance during filtration and lubrication. There are other factors that must be taken into account when it come to hydraulic filter selection. These variables will affect each other. To select the correct filter you need to establish the expected fluid viscosity as it varies with temperature. The following must be known: The fluid type The fluid temperature at start up The fluid temperature during normal operation Other important factors are: The required fluid cleanliness target The efficiency rating of the filter Fluid Cleanliness Targets When discussing fluid cleanliness, we refer to ISO 4406 as a method of counting and quantifying contamination in a system. The chart above shows recommended ratings for common system components. Many hydraulic manufacturers publish required fluid cleanliness levels for their equipment. Guide to Filter Placement The table below can be used as a guide for filter placement in a system. Each of the blocks ...

Understanding Filtration - Temperature and Viscosity
Understanding Filtration – Temperature and Viscosity

Understanding Filtration in Hydraulic Systems When adding filtration to an hydraulic system, it’s important to understand the role of viscosity, pressure drop, fluid cleanliness and filter efficiency (beta ratios) in the overall performance of the system. Temperature is also a key factor in determining the effectiveness of hydraulic filters. What is Viscosity? Viscosity is the measure of the resistance of a fluid to deform under sheer stress. It is commonly perceived as thickness, or as a resistance to pouring. It may also be described as a fluid's resistance to flow, or a measure of fluid friction. Water has a low viscosity, and honey has a high viscosity. However, viscosity can be affected by changes in the fluid temperature. For example, when heated, honey will flow more easily. Understanding the behaviour of a fluid's viscosity is an important part of understanding filtration technology. Pressure Drop Pressure drop is a measure of how much pressure is required to push a fluid through a restriction, or 'orifice'. A filter element acts as a restriction when fluid is flowing through it. The level of ...
