Hydraulic Cartridge Pressure Control Valve Free Of Load Impact - China

The original manufacturer could not reduce the impact load of the Hydraulic Cartridge Pressure Control Valve, and AAK solved it with 3 Skills Balram is from a hydraulic equipment manufacturing company in Chile.

The purchase of 3 years has been smooth, but the recently purchased hydraulic cartridge pressure control valve has upset him.

The hydraulic cylinder supplied by them was complained by a customer, the hydraulic shock caused serious vibration of the pipe, which was easy to crack and leak oil.

It is judged by the after-sales that it was caused by the impact load of the hydraulic cartridge pressure control valve used to control the pipeline pressure of the oil cylinder.

The impact load of the hydraulic cartridge pressure control valve must be reduced.

The hydraulic cartridge pressure control valve manufacturer advised that the impact load cannot be avoided.

Balram checked with different hydraulic cartridge valve manufacturers in China to solve the impact load of the hydraulic cartridge pressure control valve.

A week later, it was still fruitless.

Balram browsed AAK website on Google and clicked the articles or products about hydraulic cartridge pressure control valves for many times.

He left us a message: How to reduce the impact load of hydraulic cartridge pressure control valve? My reply: There are many reasons for the problem, which should be analyzed in detail.

According to the video of abnormal equipment sent by Balram, as well as the production drawings of hydraulic cartridge pressure control valves, AAK engineers judged that the structure should be optimized and AAK is 90% confident to be successful.

Balram saw the hope and asked AAK to make samples.

After 35 days, AAK sent 12 samples of hydraulic cartridge pressure control valves.

Last week, Balram said that it had been 9 months since AAK hydraulic cartridge pressure control valve was used on the hydraulic cylinder, and the pipeline was free of vibration and cracking.

The customer was very satisfied with this after-sales service.

His boss has decided to replace all the hydraulic cartridge pressure control valves on this batch of hydraulic cylinders with AAK ones, so AAK can prepare materials in advance.

According to the schematic diagram provided by Balram, AAK optimized the original structure of the hydraulic cartridge pressure control valve.

It can realize small opening throttle back pressure, and meet large opening oil return to reduce pressure impact.

It can effectively reduce the peak value of pulsating pressure impact generated by high-frequency commutation, avoid pipeline vibration impact damage, and reduce the impact load on the connection between the vibration table and the hydraulic cylinder.

AAK made below 3 changes: 1 - A cavity with a stop is formed between the upper part and the lower part of the valve body, and the upper end of the valve spool in the cavity is against the positioning nut.

2 - A sliding block is arranged in the middle of the valve spool, a stop is arranged at the lower part, a pressure regulating spring is arranged below the stop, and the pressure regulating spring is fixed on the spring seat.

3 - The spring seat is pressed on the plug, with an adjusting bolt in the middle.

One side of the lower part of the valve body is provided with a radial oil inlet hole and an axial control hole connected with it.

The other side is provided with a radial oil return hole, a damping hole and an axial oil return hole connected with both holes.

The axial control hole is connected with the upper oil hole on the shoulder of the upper valve body.

AAK hydraulic cartridge pressure control valve, no impact load, you can also have a small try! AAK HYDRAULIC CARTRIDGE VALVES (412) 2022-11-16
