Qingdao Zhiyuan Valve Manufacturing Co., Ltd.

Filter is to remove a small amount of solid particles in liquids of small equipment, the normal work of the protection equipment and conveying medium piping is indispensable in a device, which can effectively filter size close to the pollution sensitive element key moving dynamic oil film thickness of the particulate pollutants. The removal rate of suspended solids in water can reach more than 95%, and some removal of organic matter, bacteria, viruses, colloids and iron can be removed.. Usually installed in the valve, pressure relief valve, water valve or other equipment to the inlet end, to protect the normal use of the valve and equipment. When the fluid into the home of a certain size filter cartridge, the impurities are blocked, and clean filtrate from the filter outlet discharge, when cleaning, as long as can be disassembly of the filter cylinder is removed, you can reload after treatment. Therefore, the use of the maintenance is very convenient. Below Qingdao filter production of small series to introduce you.

The filter China has already applied filtration technology in production, and the paper has been made of plant fiber in 200 BC.. Cai Lun improved the paper law in 105 ad. He wandered in dense in papermaking during plant fiber pulp fine bamboo. Water curtain gap filtration, a thin layer of wet pulp left in the bamboo surface, after drying into paper.

The filter is made of the simplified, stainless steel filters, the sewage part, the transmission device and the electrical control part.. When the filter works, the water from the gate is filtered into the filter, and through the filter, the process is circulated through the outlet of the user, and the particles in the water are trapped inside the filter.. This constant cycle, more particles are trapped down, filtration speed becomes slower, while imports of sewage are flowing into the, the filter holes will be more and more small, so in between the inlet and outlet pressure difference is generated, when the difference of the magnanimous reaches the set value, differential pressure transmitter the electrical signal to be transmitted to the controller, control system start driving motor through transmission assembly to drive the shaft to rotate, and the sewage outfall opened, discharge from the outfall, when after the filter cleaning, pressure dro to the minimum, system returns to the initial filter shape, the normal operation of the system.

The filter is made of shell, multi filter element, anti - washing mechanism and differential pressure controller. The diaphragm of the shell will be the cavity is divided into an upper and lower cavity, the cavity is equipped with a plurality of filter, so as to make full of the spatial filtering, significantly reducing the size of the filter, cavity is installed recoil Xipan. The filter adopts the high strength wedge filter, and the filter element is controlled by the pressure difference and the time control.. When the filter inside the impurities accumulate in the filter surface caused by the inlet and outlet pressure difference increases to set value, or the timer reaches the preset time, electric control box issued a signal, drive anti flushing mechanism. When the backwash suction inlet and the filter element are imported pair, the sewage valve is opened, when the system pressure relief drainage, sucker and the inside of the filter appears a relative pressure below the filter lateral hydraulic pressure zone, forcing part of clean circulating water from the outside of the filter into the inside of the filter, adsorption in the filter on the inner wall of the impurity particles with the water flow into the tray of Rang and is discharged from the drain valve. The specially designed filters make the filter element internally and any impurities will be washed away from the smooth inner wall.. When import and export filters pressure returned to normal or timer setting time end, the whole process, material flow, backwash water consumption is low, the realization of the continuous and automatic production. Filter is widely used in metallurgy, chemical, petroleum, paper, pharmaceutical, food, mining, power, urban water supply areas. Such as industrial wastewater, circulating water filtration, emulsion of regeneration, oil filter processing, metallurgical industry, continuous casting water system, blast furnace water system, hotrolled with high pressure water descaling system. Is an advanced, efficient and easy to operate automatic filter.
