Originally, the hydraulic manifolds had to need after-sales service 4 times a year, and there is no jamming fault after using AAK’s

There is a spread in the hydraulic valve industry: those who can do a good job in hydraulic valves may not be able to do a good job in hydraulic manifolds; those who do a good job in hydraulic manifolds, and basically can do a good job in hydraulic valves. Baptiste is from DMH France. The hydraulic manifolds purchased in Italy before was transferred to the hydraulic valve manufacturer who has cooperated for 4 years. However, he suffered from the 4 times a year after-sales of hydraulic manifolds. In the second half of last year, Baptiste purchased 30 hydraulic relief valves from AAK, which is the 4th time of purchasing in the year, and the quantity is the same every time. It is a little strange. After communication, I learned that a hydraulic equipment developed by them at the beginning of last year has stains on the hydraulic oil every few months, resulting in the jamming of the hydraulic relief valves. The replacement of 4 times a year keeps the customer complaining.

 

According to Baptiste's description, the probability is that the hydraulic manifold design is improper. I suggested that he send us the hydraulic manifold drawing and system schematic diagram. Baptiste said that the hydraulic manifold drawing and system schematic diagram are confidential documents and he must get approval from boss before sending them to AAK. Three days later, Baptiste sent us the hydraulic manifold drawing and system schematic diagram, requiring that they should not be revealed to any other people. According to the analysis of the drawings, AAK engineers found that when the hydraulic power is input and the system does not start working, the hydraulic relief valve does not reach the opening pressure and cannot relieve the pressure, resulting in the increase of oil temperature and easy oil pollution. It is certain that the problem lies in the design of hydraulic manifold.

 

I suggest redesigning the hydraulic manifold. The idea is as follows: AAK will change the 2 hydraulic relief valves on the hydraulic manifold block to use the hydraulic directional control valve alone, and change the oil circuit design. The principle is as follows: when the hydraulic system works, the hydraulic directional control valve cuts off the oil circuit, making the high-pressure oil enter the working branch. When the hydraulic system stops working, the high-pressure oil directly returns to the oil tank after passing through the directional control valve to realize zero pressure unloading. If the hydraulic manifold designed by AAK is not improved, no fee will be charged. Baptiste was a little interested after learning that. 45 days later, AAK sent a new hydraulic manifold. 4 weeks later, Baptiste informed by email that the hydraulic manifold of AAK had been used for 1 month, the hydraulic oil had no pollution, the whole hydraulic system was more sensitive, and the problem that had plagued them for 1 year was solved at one time.

 

AAK hydraulic manifolds had been tested for first-line brands since 7 years ago. If meeting the following 3 points at the same time, there may be no second hydraulic manifold manufacturer in Ningbo except for AAK:

 

1. AAK technical team has engineers from the world's top 500 hydraulic manifold enterprises. They have their own experience in material selection, production drawing design, oil circuit design and production quality control.

 

2. Before hydraulic manifold assembly, the valve block shall be deeply cleaned to ensure 100% impurity free. Each valve shall be tested.

 

3. Only technicians with more than 10 years of experience are qualified to assemble the hydraulic manifolds. After assembly, use the test bench to debug the hydraulic manifolds for many times to ensure that the act function of the circuit is accurate and reliable.

 

Baptiste privately informed that the boss was very satisfied that he found a reliable hydraulic manifold manufacturer, solved the after-sales troubles of the whole year, and could be promoted to the manager of the procurement department next month. Baptiste was so happy.

 

AAK hydraulic manifold block is professionally designed to save you worry and effort. You can also have a small try!
