Hydraulic Cartridge Relief Valve Squeal Solution - China
price: 180.00 Dollar US$
AAK solved the squeal of the hydraulic cartridge relief valve with a small trick, and Chapman abandoned the original hydraulic valve manufacturer Chapman comes from a hydraulic equipment manufacturing company in Italy.
He has been in the company for 3 years and is highly regarded by his boss.
However, the hydraulic pilot relief valves purchased at the beginning of the year has been in a big trouble, which makes his boss more and more disappointed with him.
They sold a batch of hydraulic power units, and there was squeal or vibration.
They judged that it was caused by the abnormality of the hydraulic pilot relief valve.
However, when they tested the hydraulic pilot relief valve separately, the parameters met the standard, and no abnormality was found.
In a week, Chapman contacted different hydraulic valve manufacturers online and offline, but it was fruitless.
The original manufacturer of the hydraulic pilot relief valve could not provide constructive suggestions.
The boss is urging the after-sales plan.
Chapman has not found the root cause of the equipment howling yet and has a big headache.
Chapman tried to source Chinese hydraulic valve manufacturers on Google.
He was surprised that AAK's natural ranking in Google actually ranked on the home page.
He left a message to ask if AAK could solve the squeal of the hydraulic pilot operated relief valve.
I didn't answer yes or no, but only sent him two links about the squeal solution of the hydraulic valves.
AAK has solved the squeal of the hydraulic relief valves for 2 customers.
10 minutes later, Chapman sent the drawings of the hydraulic pilot operated relief valve and the product pictures of the original manufacturer.
Our engineer asked him to separate the hydraulic relief valve into two halves along the axis of symmetry, with partial drawing pictures.
The next day, I told him that it was not difficult to stop whistling, it is better to make samples directly.
After 50 days, AAK sent 40 samples of hydraulic pilot operated relief valves for him to replace the ones on the equipment complained by customers.
Last week, Chapman sent a PO for 360 hydraulic pilot operated relief valves, and told that it had been 6 months since AAK hydraulic pilot operated relief valves have been used on the equipment.
There was no customer complaint about squeal or vibration, and the customer was satisfied.
His boss asked him to replace all the original hydraulic pilot operated relief valves and only choose AAK.
Different hydraulic relief valves have different causes of squeal, it needs a case by case analysis.
Our engineer found that the dynamic performance of this hydraulic relief valve was not very smooth, so he set dynamic damping in its valve spool cavity.
This damping and spring cavity constitute a first-order inertial link.
The turning frequency is higher than the natural frequency of the second-order oscillating link of the valve spool, which can form an inter stage dynamic pressure feedback, improve the dynamic process, and effectively reduce the vibration of the dynamic process.
The greater the vibration, the stronger the damping effect.
AAK hydraulic pilot operated cartridge relief valve, no squeal, no vibration, you can also have a small try! AAK HYDRAULIC CARTRIDGE VALVES (383) 2022-10-28
