How to extend the life of the solenoid valve

The NORGREN solenoid valve in the UK has a closed cavity. There are through holes in different positions. Each hole is connected with a different oil pipe. The middle of the cavity is a piston. On both sides are two electromagnets. Which side of the magnet coil is energized? Which side is attracted to, by controlling the movement of the valve body to open or close different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then the pressure of the oil pushes the oil cylinder The piston, which in turn drives the piston rod, drives the mechanical device. This controls the mechanical motion by controlling the current through and off of the electromagnet.

The failure of the Novo solenoid valve will directly affect the action of the switching valve and the regulating valve. The common faults are that the solenoid valve does not operate. The following aspects should be checked:
1. The solenoid valve terminal is loose or the wire ends are off. The solenoid valve is not allowed to be energized and the wire end can be tightened.
2. The solenoid valve coil is burnt out. The wiring of the solenoid valve can be removed and measured with a multimeter. If the circuit is open, the solenoid valve coil is burnt out. The reason is that the coil is damp, causing poor insulation and magnetic leakage, causing the current in the coil to be too large and burning, so it is necessary to prevent rainwater from entering the solenoid valve. In addition, the spring is too hard, the reaction force is too large, the number of turns of the coil is too small, and the suction force is insufficient to cause the coil to burn. For emergency handling, the manual button on the coil can be turned from the 0 position in normal operation to 1 position, causing the valve to open.

The British Novo solenoid valve is composed of a solenoid and a magnetic core and is a valve body containing one or several holes. When the coil is energized or de-energized, the operation of the core will cause fluid to pass through the valve body or be severed to achieve the purpose of changing the direction of the fluid. The electromagnetic component of the solenoid valve is composed of a fixed iron core, a moving iron core, a coil and the like; the valve body portion is composed of a sliding valve core, a sliding valve sleeve, a spring base and the like. The solenoid is mounted directly on the valve body and the valve body is enclosed in a sealed tube to form a compact, compact combination. The solenoid valves we commonly use in production include two-position three-way, two-position four-way, and two-position five-way. Here we first talk about the meaning of the two: for the solenoid valve is the charging and power loss, for the valve is controlled to open and close.
