The flow rate of the screw pump is linearly related to the rotation speed. Compared with the low-speed screw pump, the high-speed screw pump can increase the flow rate and the lift, but the power is obviously increased. The high rotation speed accelerates the abrasion between the rotor and the stator, and must ensure that Premature failure of the screw pump, and the fixed rotor length of the high-speed screw pump is very short, it is easy to wear, thus shortening the service life of the screw pump, reducing the speed through the speed reducer or stepless speed regulation mechanism, so that the survey speed is kept at each Within a reasonable range below 300 rpm, the service life can be extended several times compared to a high-speed screw pump.
There are many kinds of screw pumps. Relatively speaking, the imported screw pump is designed with reasonable materials and excellent materials, but the price is relatively high, some services are not in place, parts are expensive, and the ordering cycle is long, which may affect the normal operation of production. Most of the domestic production of imitation of imported products, product quality varies greatly, in the selection of domestic production of products, when considering its cost-effective, choose low-speed, long lead, transmission components, material quality, long life rating of the product.
The screw pump is a positive displacement rotary pump. When the outlet end is blocked, the pressure will gradually increase to exceed the predetermined pressure value. At this time, the motor load increases sharply. The load of the related parts of the transmission machinery will exceed the design value. In severe cases, the motor will be burned and the transmission parts will be broken. In order to avoid the damage of the screw pump, a bypass relief valve is generally installed at the outlet of the triple screw pump to stabilize the outlet pressure. Keep the pump running properly.
The screw pump must not be allowed to operate in the event of a broken material. Once it occurs, the rubber stator will produce high temperatures and burn out due to dry friction. Therefore, the crusher is in good condition, and the smooth grille is one of the necessary conditions for the normal operation of the screw pump. For this reason, some screw pumps also have a shut-off device installed on the pump body. When the cut-off occurs, due to the self-priming function of the screw pump, a vacuum will be generated in the chamber and the vacuum device will stop the screw pump. The pursuit of “taking science and technology as the guide, pursuing survival with quality, pursuing market with integrity, and developing with products†has created a high sense of responsibility and a spirit of continuous innovation.
