　　Alarm principle of oil filter:

　　Alarm is a kind of electronic product which can remind or warn us to take some action in the form of sound, light, air pressure, etc. in order to prevent or prevent the consequences of an event. The alarm is divided into mechanical alarm and electronic alarm. With the progress of science and technology, the mechanical alarm is more and more replaced by the advanced electronic alarm, which is often used in the fields of system failure, safety prevention, transportation, medical aid, emergency relief, induction detection and so on, which is closely related to social production. Such as: door magnetic sensor and gas induction alarm.

　　Solution to alarm of tya150 vacuum oil filter:

　　1. Check the causes of the alarm of the oil filter, whether the pressure is too high, whether the power supply is overloaded, and whether the filter element is blocked.

　　2. Check whether the alarm wiring is connected wrongly.

　　3. Check whether the sound controller inside the alarm is damaged.

　　4. Replace the temperature alarm of Chongqing Zhongjing filter equipment with a new one, and the manufacturer will directly deliver the product within 3 years of warranty.

　　Other precautions for tya150 vacuum oil filter:

　　1. Oil filter does not feed oil:

　　1.1 the oil inlet filter element is blocked.

　　1.2 the oil inlet solenoid valve is damaged.

　　1.3 the oil suction port is sucked onto the tank wall.

　　1.4 the oil inlet ball valve is not opened.

　　1.5 there is oil in the vacuum tank, and the floating ball does not reach the low liquid level.

　　1.6 the floating ball is damaged.

　　1.7 the electrical circuit falls off.

　　1.8 oil viscosity is too high.

　　2. The oil filter always feeds oil:

　　2.1 the oil inlet solenoid valve is damaged.

　　2.2 the floating ball is damaged.

　　2.3 the floating ball cannot reach the high position.

　　2.4 inlet and outlet oil balance or line fault.

　　2.5 vacuum degree is too low (- 0.07MPa).

　　2.6 the oil inlet filter element is partially blocked

　　3. The oil filter does not output oil or the oil output is not enough:

　　3.1 no oil.

　　3.2 the oil pump inlet or shaft seal leaks.

　　3.3 the oil outlet filter element is blocked and the pressure controller is broken.

　　3.4 stop the oil pump or disconnect the coupling.

　　3.5 the oil outlet valve is not opened.

　　3.6 the lift is too high.
