Apart from the ingress of debris, the greatest danger to any design of a pump is cavitation. The phenomenon can be found in centrifugal (i.e. impeller) or positive displacement (i.e. gear, gerotor or vane) pumps, in both oil and coolant applications. Excessive cavitation can lead to erosion damage. It is important to understand how cavitation occurs as there are some misconceptions and confusion on this topic.
Read MoreThe major purpose of lubrication oil is to provide low bearing friction, to transfer heat and to protect components from corrosion. Contaminants will affect the oil’s ability to meet these requirements.
Read MoreMany OEMs are battling to improve vehicle durability, increase efficiency and reduce noise, but are struggling to find the answers. Unfortunately, many of the recent design trend are forcing higher aeration levels, and far too many OEMs are unaware.
In the pursuit of greater efficiency, many OEMs are making design decisions that may amplify the effects of oil aeration. Air bubbles may seem benign, but they can detrimentally affect the performance and durability of engines, drivelines and hydraulic equipment.
Read MoreWe sat down with OEMs, seasoned pump design release engineers and validation technicians. We wanted to understand the most frequent variable displacement vane pump failures and how someone developing these pumps could avoid them.
Read MoreIncreasing electrification of traditionally mechanically-driven components in the automotive industry has been visible in many segments of the vehicle subsystems, such as lubrication circuits and cooling circuits. Some of the components include electric oil pumps, electric water pumps, electric coolant valves, etc. As the parts evolve from purely mechanical components to a combination of mechanical and electronic hardware, the methods used to validate the components have also evolved.
Read MoreMany people question the value of contracts but only consider support when things go wrong. In this blog post we discuss how you can save money if things go wrong, save time when help is needed and make money by increasing efficiency.
Read MoreTell me if this sounds familiar: you want to increase efficiency and capability but your testing equipment scope is compromised by a yearly budget. It can be frustrating, but there are other options and here we will discuss one of them. Let’s explore the benefits of outsourcing your component testing and whether it makes sense for you.
Read MoreIn a world where development cycles are moving faster than ever before, OEMs are simultaneously pushing some of the biggest engineering initiatives automotive has ever seen. This is why having the right testing solution is so important. The first question arises: whether or not to build internally, custom engineer or order a turn-key test system.
Read MoreATA, a leading international component test solutions company, today announced the Ensure product line of test systems. These systems are designed to benchmark performance and capture the unique failure modes of specific thermal/hydraulic components (i.e. pumps, valves, heat exchangers, etc.), accelerating the product development cycle and helping to ensure the reliability of components on the road.
