Using method, common trouble and solution of stainless steel plate and frame filter press

Stainless steel plate and frame filter press is a kind of product that integrates coarse filtration, fine filtration and ultrafiltration The main condition is to select different filter media according to the user's requirements for the production of products, so as to achieve the purpose of decarburization, clarification and sterilization, and also can be used as residue and water treatment It is widely used in the preparation of large and medium-sized hospitals, the production of infusion oral liquid in pharmaceutical factories, the filtration of mineral water in wineries and beverage factories, and the clarification and filtration of liquid in light industry, chemical industry, metallurgy, electronics, environmental protection and other departments Instructions for use of stainless steel plate and frame filter press 1 Wash repeatedly with 3-5% sodium carbonate solution, and then rinse with clean water, and then disinfect and test the pH value to the allowable range 2 Check whether the silicon rubber ring of the filter is placed smoothly to prevent water leakage The thin filter material can be moistened with distilled water and then pasted on the filter plate The filter plate should be placed in the silicon rubber ring to compress the top plate 3 When starting the infusion pump, first close the liquid inlet valve, then start it, pay attention to the rotation direction of the motor, gradually open the required pressure of the liquid inlet valve, and discharge the air, then it can be filtered, and the general working pressure is less than 0.1-0.2mpa 4 Pay attention to the increase speed and sudden drop of the pressure gauge when using, so as to judge whether the filter material is blocked or broken 5 When stopping the pump, close the liquid inlet valve first to prevent the filter material from being damaged by the liquid backflow of suddenly stopped pump, then stop the pump and open the vent bolt, loosen the top plate after the filtrate is exhausted, then replace the filter material and clean it 6 If the machine adopts microporous filter membrane for fine filtration, the coarse filter material must be used for the feed liquid first, and then it can be used after pre filtration to avoid blocking microporous filter membrane and affecting the filtration quality 7 Applicable filter media: gauze, linen, cotton cloth, silk cloth, canvas, nylon silk, filter paper, asbestos board, microporous filter membrane and ultrafiltration membrane Possible faults and solutions: causes of pump water (liquid) failure after startup: 1 Water leakage of pump water inlet pipe 2 Blockage or excessive resistance of pump water inlet pipe 3 Excessive water absorption height of pump 4 Tax leakage of pump seal 5 Wrong rotation of pump impeller 6 Solutions to insufficient water diversion: 1 Plugging and repairing water leakage 2 Cleaning water absorption pipe and shortening water diversion pipe 3 Reducing water absorption height 4 Replace or adjust the sealing ring 5 Change the direction 6 Add enough water to lead the water fault: the cause of the water leakage of the clamping ring: 1 The clamping ring screw is not tightened or the washer is damaged solution: 1 Tighten the clamping ring screw or replace the washer fault: the cause of the excessive noise of the pump: 1 The friction between the impeller and the pump cover, the end screw is loose 2 The idling damages the sealing ring 3 The solution of suction air: 1 Install the pump cover correctly and tighten the impeller end screw 2 Replace the sealing ring 3 Adjust the liquid inlet position and replace the repair pipe
