At this time, it is generally necessary to interrupt the filtration operation, replace the filter element or take it out for cleaning, which is time-consuming and laborious, affecting the treatment efficiency.The new JSLS automatic backwashing water filter is a good solution to this problem, as it has the advantages of continuous filtration, automatic backwashing and drainage, compact structure, smooth and reliable operation, large capacity, low running costs and long service life.    The cleaning and draining process of JSLS type automatic water filter is carried out automatically during the operation of the equipment, and the filtering operation can still be carried out while backwashing and draining, without affecting the normal water supply. This filter is mainly used for coarse and fine filtration of power station auxiliary cooling water, industrial circulating water, fire-fighting water, washing liquid and other similar suspended liquids.Two.Machine construction and working principle1. Machine structure The sketch of the water filter structure is as follows:     The drive device is composed of motor and reducer, which drives the transmission shaft to rotate at a low speed, and has the characteristics of large torque, high reliability etc.     If an accidental blockage occurs and the torque exceeds the maximum design value, the electrical protection system will automatically stop and send an alarm signal.   The filter elements are fixed to the intermediate disc and are evenly distributed on the inner and outer circumference to ensure maximum filtration area within the fixed shell volume. Each filter element (cartridge) is cylindrical and uses wedge-shaped cross-sectional corrosion-resistant steel wire strips welded to the upper and lower heads, the interval of each wire strip is evenly arranged with equal gaps according to the requirements of filtering precision, and there are also multiple ring hoops welded in the length direction, the cartridge not only has sufficient rigidity and strength against deformation, but also can strictly guarantee the precision of filtration.    Backwashing device backwashing device consists of a rotating arm and sealing mechanism, connected to the drive shaft, is the only rotating part in the machine, low speed, smooth operation, while using a special mechanical seal structure design, with good sealing performance, wear and tear automatic compensation function, to ensure the smooth realization of backwashing and the normal and reliable operation of the machine.     The differential pressure controller introduces a double contact differential pressure controller with a bellows type sensor for neutral gases such as air, gas and water vapour and liquid media such as water, oil and refrigerant. The controller has an adjustable set value and an adjustable range of 0.02 to 1.6 MPa and a working pressure range of 0.05 to 2.5 MPa.    The blowdown valve technology of connecting the electric blowdown valve with the blowdown pipe mouth and the electric ball valve produced by key parts are especially suitable for the filter residue with large silt content, which will not be leaked due to torque overload or lax closure, and at the same time, it has the advantages of reliable use and long service life.2.Working principle   Both the filtering and backwashing propulsion of the machine are provided by the raw water pressure head or pump lift. The pressure in the filter chamber of the system remains basically constant, the liquid flows outwards from the inner chamber of the filter element and the entrained solid impurities are intercepted on the inner surface of the filter medium, causing the pressure difference between the inner and outer chamber to rise and the filtering resistance to increase gradually.   When the pressure difference between the inner and outer cavity exceeds a certain setting value of the differential pressure controller, the differential pressure controller sends out a signal to control the motor to start, driving the backwashing arm to rotate and opening the electric drain valve at the outlet of the drainage pipe at the same time.  Wh
