Every industry that requires the testing and calibration of pressure equipment such as pressure transmitters, gauges, and switches relies on hydraulic hand pumps. They play a vital role in everything from energy generation to health care to construction and wastewater management, ensuring that our global economy runs smoothly and safely.
With such a diverse range of applications, there isn’t a single hand pump that can meet all of them. In this post, we’ll go over the fundamentals of hydraulic hand pumps and highlight some of its most crucial features, myths, and manufacturer like riverlakeco who produce the best quality products.
Myths About Hydraulic Hand Pump
Porto-power sets, collision repair kits, and maintenance kits are all names for hydraulic hand pumps and cylinder sets. A “set” is typically made consisting of a pump, cylinder, and hose connected by a coupler. They, like any hydraulic equipment, require love and care in order to last longer. Knowing how to use and care for them can help you save time, money, and possibly your life. The problems listed below are just a few of the more prevalent ones that we’ve seen at Gustin Hydraulics throughout the years. Other, less prevalent concerns will be discussed in future posts.
Myth No. 1
The release valve must be faulty if the pump will not hold or develop pressure. When used correctly, this is probably the LEAST likely issue. But here’s what could happen: Convinced that this is the issue, the operator applies so much force to tighten the release that the ball or cone on the release spindle drives right through the valve seat! – We’ve witnessed it firsthand. Because the release seat is machined straight into the base of the hand pump, if this happens on most types, the pump is beyond economical repair.
Another common occurrence is when the operator backs out the release so far that the valve ball falls out unnoticed. When the valve spindle is reinstalled, the end of the stem, which is where the ball should be, can damage or drive right through the seat, as in the prior example.
Myth No. 2
My pump will only advance the cylinder halfway before stopping. It’s probably running out of oil. This is the most likely scenario, but keep an eye out for an overfilled pump. Isn’t that insane? Here’s how it goes: The reservoirs of most hand pumps are not ventilated. In a later blog, we’ll discuss vented ones. When you operate the pump to advance your cylinder with an overfilled tank, a vacuum forms in the tank as the oil escapes. The pump can only overcome the vacuum up to a certain extent before acting as though it’s running out of oil. Fill your pump according to the manufacturer’s recommendations. If you don’t have them, you can find breakdowns and operation manuals in our extensive components breakdowns area here ” “. Otherwise, a reasonable rule of thumb is to fill the reservoir to around 75% of its capacity with your cylinder fully retracted. Some pumps even come with a handy dipstick.
Myth No. 3
If my pump won’t retain pressure, it’s because it’s out of oil. If the pump is low on oil, it won’t be able to build pressure past the point where it runs out. That’s all there is to it.
Myth No. 4
My pump isn’t working at all, thus it’s probably low on oil. While a pump will not function without oil, there are numerous other reasons for a pump’s failure. Not to mention the subject of why your pump is running low on oil. A worn-out safety by-pass valve is another item that could be wrong with your pump. Contamination in the valves or valves that have become worn Resurfacing or replacement is required. Seals that have become worn or blown.
Three Important Characteristics of Hydraulic Hand Pumps
Since their humble beginnings, hydraulic hand pumps have come a long way. There are many different types and pressure ranges available today, but they are all designed to be durable, lightweight, and simple to use. However, there are a few key features of the hydraulic hand pump that are worth mentioning, especially when compared to their pneumatic counterparts.
- Efficiency – Hydraulic pressure is one of the most energy-efficient techniques of transmission. With just one or two squeezes of the handle, you can achieve high amounts of pressure with a hydraulic hand pump. Because air is compressible, a pneumatic pump would require significantly more work to achieve the same levels of pressure.
- Precision – When a high degree of fine-tuning is required, hand-operated hydraulic pumps are perfect. They’re usually designed with tiny adjustment knobs that allow the operator to fine-tune the applied pressure to within.01 psi (.069 kPa).
- Stability – To limit leaks, prevent maintenance, and assure temperature and pressure stability, hydraulic hand pumps are often composed of cast or machined metal.
Hydraulic hand pumps, in general, are intended to improve your operational efficiency. They come in a variety of pump designs and flow rates, as well as varied pressure options to suit different applications.
If you work in the energy, oil, or natural gas industries and need to calibrate instruments on a regular basis, riverlakeco has hydraulic Hand Pump models that are well worth considering. You can also look at the various products offered by the manufacturers that are best in the market and meet the standard quality.
