Drainage pump model and product introduction
Drainage pump is also a kind of centrifugal pump, drain pump models are many, but are basically used to drain the pool or large liquid storage tank. Its working principle is: relying on high-speed rotating impeller, liquid under inertial centrifugal force obtained energy to increase the pressure. Today we come to understand the drainage pump model knowledge. Drainage Pump Model and Product Information Submersible Sewage Pump Specifications Models commonly used in AS (liquid submersible sewage pump), QW / WQ (non-clogging sewage pump), JYWQ (automatic mixing sewage pump), WL (vertical sewage pump) ZW (self-suction sewage pump) and other series. Of these drainage pump models, the most representative should be QW / WQ (non-clogging sewage pump), we focused on this type of drainage pump to explain. First, the product overview WQ submersible sewage pump main components from the impeller, pump body, base submersible motor. Pump and motor are the same shaft, because the pump is located at the bottom of the entire sewage pump, it can maximize the suction area of ​​the remaining sewage. Impeller for the double flow channel design, greatly improved the ability of dirt flow, can effectively pass the diameter of the pump diameter of 50% of the solid particles. Product implementation Q / TBJW2-2003 "sewage sludge submersible pump" standard. Second, the product features 1, the cable is durable, waterproof: heavy-duty rubber flexible cable, resin infusion, compression fixed, no pull, long-term reliable. 2, double seal, double protection: double machine seal series configuration, the real double protection to ensure motor safety. 3, multi-channel detection, multi-channel protection: oil-water probe, float switch, can be real-time detection and alarm, shutdown, fault signal retention and other functions to make submersible motor safe and reliable. 4, over-flow ability: dual-flow design, to ensure high efficiency pump without congestion. 5, easy maintenance: the use of dual-rail coupling device, so that when the pump take off and landing without underwater operation, easy maintenance, saving time and labor. Third, the working conditions Flow range: 2 ~ 1500m3 / h Head range: 3 ~ 45m Speed ​​n: 970 ~ 2900r / min Ambient temperature T: ≤ +40 ℃ Medium temperature: -15 ℃ ~ +60 ℃ Medium density: ≤ 1.3X103kg / m3 Medium PH value range: 5 ~ 9 The system maximum working pressure: ≤ (Editor: Yunhai QQ:) Recommended reading: Agent procurement drainage pump working principle of interpretation
