Electromagnetic valve is used
Sex line of fluid must and the electromagnetic valve series in the model calibration medium consistent. The temperature of the fluid must be less than choose solenoid valve calibration temperature. Electromagnetic valve allows liquid viscosity in general and the CST, more than twenty CST should be marked. Work pressure difference, line the most high differential pressure is less than 0.04 MPa should choose such as ZS, 2 w, ZQDF, ZCM series straight acting and step straight acting; The minimum differential pressure greater than 0.04 MPa can choose pilot operated differential electromagnetic valve; Maximum working pressure difference should be less than the maximum electromagnetic valve set pressure; General electromagnetic valve are unidirectional work, so should pay attention to whether there is a reverse pressure difference, if installation check valve. Fluid cleanness is not high in electromagnetic valve should be installed ahead of filter, general solenoid valve to medium is better for clearness. Pay attention to flow aperture and take over diameter; Electromagnetic valve usually only switch the two control; The condition allows please install bypass pipe, facilitate maintenance; A water hammer to customize the electromagnetic valve opening and closing the time adjustment. Pay attention to environment temperature on the influence of electromagnetic valve power supply current and consumed power should be based on output capacity selection, the power supply voltage generally allow plus or minus 10% or so, must pay attention to communication starting VA value is higher.
Electromagnetic valve reliability
Electromagnetic valve is divided into normally closed and normally open two; General selection normally closed type, electricity power open, close. But in the open time is very long closed very short time to choose the normally open type. Life test, the factory generally belongs to the type testing project, specifically our country haven't electromagnetic valve
Electromagnetic valve has closed cavity, in different locations are open through-hole, each hole all leads to the different electromagnetic valve
The tubing, cavity intermediate is valve, both sides are two pieces of electromagnet, which face the magnet coil electricity will be attracted to the body which side, by controlling the movement of the body to block or leak out different discharge hole, and the oil hole is always open, hydraulic fluid will enter the different oil drain, and then through the oil pressure to push oil cylinder piston, piston and piston rod driven, piston rod drive mechanism motion. So through the control electromagnet electric circulation fault controls the mechanical movement. Fault and eliminate
