Embodiment one and embodiment two CAF automatic water filter, it can be installed according to the position and the trend of original pipeline, reserves the dismouting space of filter screen 2 during the installation. The drain pipe is an emptying pipe 14, the length of the emptying pipe can be reduced as much as possible in order to reduce resistance as much as possible, the electromagnetic valve 12 can be connected with a backwashing valve, and the emptying pipe 14 can be connected with the backwashing valve. The solenoid valve 12 is preferably mounted upright to avoid contamination by foreign materials. The drain pipe of the backwash structure should have a diameter greater than or equal to the diameter of the drain pipe 14 and a length less than 15 feet, should have less than or equal to two bends installed in it, and preferably does not employ an upwash pipe. An exhaust valve should be included in the inlet line to avoid water hammer formation. The preferred parameters of the control hose of the electronic control system of its electronic control box 11 are: the minimum working pressure is 0.2Mpa, the pressure loss when the filter is cleaned is 0.015Mpa, the highest working water temperature is 65 ℃, and the working power supply is 400VAC and 0.55 KW.

The control panel, as an operation panel, may be provided with a touch screen 17, which may be provided with two interfaces, a parameter setting interface and a manual/automatic operation interface. After the filter is electrified, the parameter setting is firstly carried out, the control mode of the filter can be a three-level control mode, the manual cleaning operation is prior, the differential pressure signal control is prior, and the time control is carried out. After setting parameters, counting down, starting corresponding motors to start washing (alternately starting positive and negative rotation) when the manual washing, the differential pressure signal or the counting down time and three starting conditions are met, starting an alarm signal if the continuous washing times in the differential pressure control mode exceed a set value, and receiving a manual reset key to clear the alarm after the fault is eliminated. Before the filter is opened, whether the drain pipe is smoothly connected is checked, whether valves on the water inlet and the water outlet are closed is checked, whether a drain valve 13 is closed is checked, whether a free space is reserved for maintenance and taking out of the filter screen 2 is checked, and whether line connection of an electric control system (a pressure difference controller, an electronic controller and an electromagnetic valve 12) is checked. After the filter starts, firstly slowly open the water inlet valve of the filter, then check whether the filter leaks, if leak need be solved to get rid of the leakage situation, then slowly open the water outlet valve of the filter, then slowly close the bypass valve, observe whether the operation of the filter has abnormal phenomena, check whether the water inlet pressure of the filter is greater than the maximum working pressure, whether the water outlet pressure is less than the minimum working pressure, check whether the flow of the filter exceeds the flow range of the filter. Manual backwash is initiated when: the normal operation of the filter, the emergency cleaning of the filter, the draining of the filter before maintenance, and the manual back-flushing test after maintenance are routinely checked. When the filter is stopped, firstly closing a water outlet valve of the filter, then starting a manual backwashing, then closing a water inlet valve of the filter, and then performing the manual backwashing again to release the pressure of the filter; if the filter needs to be stopped for a long time, the water in the control hose, the emptying machine shell and the valve can be cut off, then the control hose is connected again to prevent insects, dust and other foreign matters from entering, and the filter screen 2 is taken out to be cleaned by water and dried; in order to prevent the filter and its components from freezing during the freezing season, the valve, the flushing pressure differential controller, the micro-filter and the connected drain pipe should be shut off to allow the water to drain. When the filter has abnormal sound, the motor does not run when the sewage discharge is started, the water pressure of the water outlet 5 is less than the minimum working pressure, the water pressure of the water inlet 6 is greater than the maximum working pressure, or the water temperature is higher than 65 ℃, the filter is stopped for inspection, and after the electric control system is powered off, the power supply is recovered after 30 seconds. The filter should periodically clean the transmission member and periodically check the filtering mechanism, for example, open the valve for 3-5 seconds, to ensure the normal operation of the pressure gauge, check whether the cleaning seal ring has leakage, and check whether the housing 1 has damage or corrosion. This filter may be due to too low a system pressure if the backwash valve is not closed at start-up. If the pressure of the filter is too high and the backwashing is not carried out, the reason that the connection of the PLC controller is not connected well, or the power supply is not opened, or the pressure difference is adjusted too much, or the PLC controller is in failure, or the backwashing valve is not installed properly can be probably caused, and at the moment, the PLC controller is adjusted, or the power supply is checked, or the pressure difference is adjusted, or the PLC controller is checked, or the backwashing valve is checked to be installed. If the backwash valve flutters, it may be due to air in the valve cover, which should be mounted up to facilitate air removal, or several times with manual filter backwash to remove air from the interior of the machine. If the flush valve fails to close, perhaps because the valve membrane has holes or the solenoid valve has dirt, the backwash valve should be disassembled to replace the membrane or the solenoid valve 12 opened for cleaning. If when the trunk line is backwashed, the frequent continuous backwashing condition occurs, then probably because the filth that is difficult to clear away has been adhered to filter screen 2, stickness material such as oil, or the steel brush of dirt cleaner 3 blocks unable motion, should ensure that the pressure of delivery port 5 is not less than minimum operating pressure this moment, or unpack the organism apart, take out filter screen 2 and carry out rinse thoroughly, or open the organism and inspect the machine operational aspect.

The applicant states that the above description is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that any changes or substitutions easily conceivable by those skilled in the art within the technical scope of the present invention are within the protection scope and the disclosure scope of the present invention.
