Correct understanding of the electromagnetic reversing hydraulic valve should be considered factors

Connected to the electric control system and Manifold Block hydraulic working system is the electromagnetic control valve, which is the electromagnetic directional Manifold block hydraulic valve. So, what are the factors that should be considered in the correct understanding of the electromagnetic reversing hydraulic valve? Next, the electromagnetic directional Manifold Block hydraulic valve manufacturers to introduce to us.

 

1, Manifold Block electromagnetic directional valve reversing frequency:

 

The reversing frequency of Manifold Block electromagnetic reversing hydraulic valve refers to the number of reversing allowed by the cabinet per unit time. The reversing frequency of Manifold Block electromagnetic reversing hydraulic valve is mainly limited by the characteristics of the electromagnet. The starting current of the AC electromagnet is more than 3 times higher than that of the normal pulling. Regular starting will aggravate the coil heat, general AC electromagnet allowed working frequency in 60 times/min below, wet electromagnet heat dissipation condition is better, commutation frequency is higher than dry. Because the dc electromagnet is not limited by the starting current, the reversing frequency can reach 250 ~ 300 times /min, in addition, the reversing frequency can not exceed the limit of the valve reversing time, otherwise it can not complete the reversing process.

 

2, Manifold Block electromagnetic directional hydraulic valve service life:

 

The service life of Manifold Block electromagnetic reversing hydraulic valve refers to the number of reversing when the Manifold Block electromagnetic reversing hydraulic valve cannot carry out normal reversing and reset action for various reasons, or when its main performance index obviously deteriorates and exceeds the specified value. The service life of Manifold block solenoid valve mainly depends on the service life of electromagnet. In addition, the processing and manufacturing quality of various parts of Manifold Block solenoid valve and the anti-fatigue strength of return spring also affect the service life of Manifold block solenoid valve.

 

3. Working reliability of Manifold Block electromagnetic reversing hydraulic valve:

 

Working reliability refers to the Manifold block electromagnetic directional reversing hydraulic valve can be replaced reliably after being energized and reset reliably after power failure in any service occasions. The reliability of the solenoid reversing hydraulic valve mainly depends on the design and manufacture of the valve. It can reduce the various reversing resistance acting on the valve core, and ensure the machining accuracy of the valve body hole and the valve core, so as to improve the reliability of the solenoid reversing hydraulic valve.

 

4, Manifold Block electromagnetic reversing hydraulic valve reversing and reset time:

 

It is generally stipulated that the time from the electromagnet to the end of the valve core commutation is the commutation time of Manifold Block electromagnetic directional hydraulic valve, and the time from the electromagnet to the valve core back to the initial position is the reset time of the electromagnetic directional hydraulic valve. Generally, the reversing time is not equal to the reset time, but roughly the same, the reversing time of the AC electromagnetic reversing hydraulic valve is about 0.01-0.03s, and the reversing time of the DC solenoid valve is about 0.02-0.07s.

 

5, Manifold Block electromagnetic reversing hydraulic valve pressure loss:

 

The pressure loss of Manifold block electromagnetic reversing hydraulic valve is composed of flow loss and valve orifice throttling loss. Due to the small opening amount of the solenoid reversing hydraulic valve, the throttling loss is relatively large, and the pressure loss caused by oil flowing through the solenoid reversing hydraulic valve is relatively large.

 

The above is the sharing of the factors that should be considered in the correct understanding of Manifold Block electromagnetic directional hydraulic valve brought by the manufacturers.
