Cip Reflux Pump Has A Broad Application Market And Development Prospects

CIP Return Pump adopts direct-connected structure compared with similar domestic products. It has the characteristics of simple and compact structure, less vibration, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, easy use and maintenance, etc. It is the first domestic product in the sewage pump series. Various technical performance indicators are leading in China and have reached the international advanced level. It has a broad application market and development prospects. The experiment on a certain CIP reflux pump shows that its pumping capacity is closely related to the amount of liquid in the pump. When the liquid in the self-priming pump is less than 1.5L, the vacuum degree is very small, and the working state of the pump is unstable, air will leak into the pump, the cycle will be interrupted, and continuous pumping cannot be performed; when the amount of germanium water in the pump is greater than 2.OL, the return water blocks the lower tongue, and air will not leak into the pump. At this time, continuous pumping begins. The vacuum degree increases with the increase of the liquid storage in the pump. When the amount of liquid in the self-priming pump reaches 3.5L, the vacuum degree can reach 9m; when the liquid storage volume is greater than 3.5L, the vacuum degree increases slowly with the increase of the liquid storage volume.

When the suction height of the CIP return pump is too large and the liquid temperature is relatively high, the suction port pressure is less than or equal to the saturated vapor pressure of the liquid. In this environment, the liquid will boil and vaporize at the pump inlet, forming a space full of steam in the pump casing. As the pump rotates, the bubbles enter the high-pressure area. Due to the pressure difference, the bubbles are compressed and ruptured and re-condensed. At the moment of condensation, the particles collide with each other, generating a very high local pressure. With the heat released when the bubbles condense, the metal is chemically corroded. The above phenomenon is cavitation.

The CIP return pump is arranged vertically, and the pump is coaxial with the motor, so that the weight of the rotating parts is in the same direction as the water pressure borne by the impeller; secondly, the submersible sewage pump is used underwater, and the sewage medium transported contains impurities, sludge and other substances; thirdly, the submersible sewage pump is a type of centrifugal pump. When it is running, the power always increases with the increase of flow rate. When the flow rate exceeds the design flow rate and reaches a certain value, the motor will burn out due to overload. The above problems will affect the service life of the sewage pump to varying degrees. The function of the CIP return pump shaft is to connect with the motor through the coupling and transmit the torque of the motor to the impeller, so it is the main component for transmitting mechanical energy. The pump body is also called the pump casing, which is the main body of the multistage pump. It plays a supporting and fixing role and is connected to the bracket for installing the bearing.

The CIP return pump bearing is a component that is sleeved on the pump shaft to support the pump shaft. There are two types of rolling bearings and sliding bearings. The sealing ring is also called the leakage reduction ring. If the gap between the impeller inlet and the pump casing is too large, the water in the high-pressure area of ​​the pump will flow to the low-pressure area through this gap, affecting the water output of the pump and reducing the efficiency! If the gap is too small, the impeller and the pump casing will cause friction and wear. The stuffing box is mainly composed of stuffing, water seal ring, stuffing cylinder, stuffing gland, and water seal pipe. The function of the CIP return pump stuffing box is mainly to close the gap between the pump casing and the pump shaft, so that the water flow in the CIP return pump does not flow to the outside and the outside air does not enter the pump. Always keep the vacuum in the water pump! When the pump shaft and the packing generate heat through friction, the water seal pipe will be used to keep the water in the water seal ring to cool the packing! Maintain the normal operation of the CIP reflux pump.
