The quality of the three screw pumps Now on the market more types of screw pumps, relatively speaking, the entrance of the three screw pump design, material well, but the higher prices, some services are not in place, high parts prices, long ordering cycle , May affect the production of normal operation. Most domestic imitation imported products, product quality varies greatly, in the selection of products produced in the sea, considering its cost-effective time, the choice of low-speed, long lead, transmission parts of good quality, long life rating products. Three screw pump speed selection Three screw pump flow and speed into a linear relationship, relative to the low-speed screw pump, high-speed screw pump while increased flow and lift, but the power increased significantly, high speed accelerated the rotor And the stator wear, inevitable failure of the screw pump premature, and high-speed screw rotor rotor length is very short, very easy to wear, thus shortening the life of the screw pump. Through the reducer or stepless speed regulation mechanism to reduce the speed, the exploration speed maintained at more than three hundred points per minute below the reasonable range, compared with high-speed screw pump, the service life can be extended several times. Maintaining a constant outlet pressure Three screw pump is a positive displacement pump, when the outlet is blocked, the pressure will gradually increase, so that the pressure exceeds the predetermined value. At this time the motor load increased dramatically. The load on the head related parts will also exceed the design value. Avoid breaking three screw pump Never allow the case of broken material in the operation, once occurred, the rubber stator because of dry friction, instantaneous heat generated and burned, so broken crusher intact, the grid is smooth flow of three screw pump normal operation One of the necessary prerequisites, for this reason, some three screw pump is still installed in the pump body off the device, when the cut off, because of the self-priming function of the three screw pump features, the cavity will produce a vacuum, the vacuum device will make Three screw pump stop running. To ensure that debris does not enter the pump Wet sludge mixed with solid debris will damage the rubber material of the three-screw pump stator, so to ensure that debris does not enter the cavity of the pump is very important, many sewage treatment plant before the pump The installation of a crusher to destroy the machine, and some install grille devices or filters to block debris into the three screw pump, grill should be promptly clear the fishing so as to avoid clogging. Due to its variable conveying capacity, self-priming ability, reversible function and ability to transport liquids containing solid particles, the triple-screw pump is widely used in conveying water, wet sludge and flocculant liquid in sewage treatment plants . Selection of screw pump should follow the economic, fair and reliable principle. If the design selection of ill-considered, will be given after the use, management, maintenance of trouble, so the choice of a production according to actual needs, reasonable and reliable screw pump can ensure the smooth production, but also reduce the repair capital.
