As we all know, there are many hydraulic components in the hydraulic system, which contains a 24v hydraulic solenoid valve. After some use of customer feedback, they use a period of time after the discovery of 24v hydraulic solenoid valve power does not work, so what is the reason for this?
First, the hydraulic solenoid valve caused by the high ambient temperature
1, the system temperature is too high. Low viscosity solenoid used in plastic containers will crystallise and block the orifice or harden;
2, the air gap contains iron filings, copper powder and other impurities stuck in the piston rod and stuck;
3, the oil pipe clamping, pressure increases, the flow rate increases, cutting and crushing objects to enhance the efficiency.
Second, caused by wiring breaks
1, the oil pump on the welded copper core wire (or copper cap) breakage site;
2、Output signal pipe lap part joints;
3, the connector loose contact poor place, the oil tank oil is too little to meet the specified requirements, reduce the volume and the installation of gasket paper is not enough to prevent dust place;
4, unqualified start relay, also easy to burn the coil;
Third, The control switch may fail due to the operator mistakenly pressing the ‘stop’ key or because it lacks a phase sequence protection function. This can cause a microcomputer time lag that prevents us from correcting the reverse movement on the strip drive.
Fourth, Too much leakage in the system may occur if we use an improper cleaning agent or if it does not dissolve properly. A large no-load current value may result from incorrect selection. Additionally, sealing and bracket connections may become disordered or corroded due to prolonged use and aging.
Fifth, The solenoid may be defective if the solenoid coil has a broken line or the insulation layer is burned, which can cause a short circuit between the coil or a coil short circuit. Additionally, exposed steel balls or a permanent magnet that has exceeded its service life and become demagnetized can cause problems. If the valve block or sealing ring is damaged or worn out, it is recommended to replace them. Thicker dirt may also indicate that replacement is necessary.
