     Three screw pump working note

    One, choose the speed of three screw pump three screw pump flow and speed into a linear relationship, relative to the low speed of the screw pump, the high speed of the screw pump can increase the flow and head, but significantly increased power, high speed accelerated between the rotor and stator wear, premature failure will make screw pump, and high speed screw pump rotor length is very short, easy to wear, so as to shorten the service life of the screw pump. Stepless speed reducer or by institutions to reduce speed, so that exploration speed is maintained at three hundred rpm the reasonable range, and high-speed operation of the screw pump is compared, can extend the service life several times. Two, the quality of the screw pump now the type of screw pump on the market more, relatively speaking, the screw pump designed imported, material well, but the price is high, services and some are not in place, fitting high price, order cycle length, may affect the normal operation of production. Most of the domestic production of imported generic products, product quality uneven, some good and some bad, in the selection of domestically produced products, taking into account their cost, use low speed, long lead, good transmission capacity component material, rated long life products. Three, to ensure that debris does not enter the pump wet sludge mixed with the solid debris will screw pump stator rubber material damage, so to ensure that debris does not enter the pump cavity is very important, a lot of sewage plant in the pump before the installation of a mill, also some install grid device or filter, blocking debris into the pump, for grid should be clear winners in time to avoid congestion. Four, maintaining a constant outlet pressure screw pump is a positive displacement rotary pump, when the exit blocked, the pressure will gradually increase, so that the pressure exceeds a predetermined value. When the motor load increased dramatically. Transmission machinery-related parts of the load will exceed the design value, serious when occur motor burned, transmission parts breakage. In order to avoid screw pump damage, usually in the three screw pump bypass relief valve outlet, outlet pressure to stabilize, maintain the normal operation of the pump. Five, avoid cutting three screw pump must not be allowed in the blanking case operation, once happen, rubber stator due to friction, moment generating high temperature and burn, therefore, mill intact, smooth screw pump operation grid is one of the necessary conditions, therefore, some screw Pump are pump mounted on the body through feeding stop device, when the broken material, due to its having screw pump self suction function, the cavity will generate vacuum, vacuum device can make the screw pump stops." Science and technology as the guide, to the quality of survival, to the integrity of the market, product and development" the pursuit of the enterprise in the people, created a high sense of responsibility and the spirit of continuous innovation, and dedication to customer service.
