YJ1 series oil flow relay

Products within the reality of oil flow relay transformer forced oil circulation system oil flow rate variation means. Used to monitor the oil circulation cooling system pump operation, such as whether the steering pump, the valve is turned on, the pipeline is clogged, etc., when the oil flow reaches the setting of the flow rate value of the action or return flow value can emit a warning signal. Product Attributes ambient temperature: -40 ℃ ~ + 40 ℃; when the air temperature is + 25 ℃, relative humidity less than 90%; oil temperature is not higher than 90 ℃; no severe vibration and bumps in places; transformer cooling system Relay oil parameters and flow parameters (ie operating characteristics) affect compliance. Use oil flow must ensure consistent plate and velocity, ie the movable plate resting position when the former velocity 15 ° ~ 30 °, lagging velocity 15 ° ~ 30 ° when the operating position of the movable plate to ensure the stability of the operating state when the relay installation. Precautions oil flow relay in the operation should be checked once a year and the micro switch lead insulation performance is good, the seals need to be replaced. After the functions and characteristics of the cooling system when the transformer oil flow circulation pump start there, the flow reaches the relay flow set point above the impulse relay to the final position of the movable plate, driven by coupling magnet synchronous rotation indicating portion, the pointer guiding flow position, the micro switch normally open contact closure, produces normal operating signal. When reducing the flow to relay return flow set point (or fail to meet the working oil flow), the movable plate by means of a reset action of the spring plate scroll return, micro switch is normally closed contact open, normally open contact closure, a fault signal. Note 1, oil flow relay at the factory in a dedicated flow test equipment will adjust the alarm point, users in general, do not be adjusted. 2, oil flow relay should be checked before installation in the storage and transportation process is bad and rust, action and moving parts should be flexible rotation without catching phenomenon. 3, oil flow relay should be checked prior to installation leads, outlet terminals and micro-switch insulation is good. 4, when the oil circuit, the oil flow is less than the actual provisions of the operating characteristics of the relay traffic, you can remove the relay from the pipeline, place a smooth dial down, and make the adjustment plate with the original transfer position mark, loosen the fixing adjustment plate Four M5 bolts will adjust disc rotation clockwise appropriate a certain angle, the whole adjustment process must be manually adjust the dish always has, in order to prevent the spiral spring torque and slip After adjustment should be installed each disassembly member.
