Vertical Pipeline Pump

A pipeline pump refers to a water pump that can be directly installed on a water pipeline, and can also be called a pipeline centrifugal pump. More space-saving compared to ground-mounted pumps. This pump is mainly used for industrial water transportation and urban water system. Model, different pump body materials can be selected in different transportation environments, and it is a very popular transportation equipment at present.

After the vertical pipeline centrifugal pump is started, the pump shaft drives the impeller to rotate at a high speed, forcing the liquid prefilled between the blades to rotate. Under the action of the inertial centrifugal force, the liquid moves radially from the center of the impeller to the outer circumference. When the liquid flows through the impeller, the energy star is obtained, the static pressure energy increases, and the flow rate increases. When the liquid leaves the impeller and enters the pump casing, it decelerates due to the gradual expansion of the flow passage in the casing, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipeline along the tangential direction. Therefore, the volute pump casing is not only a component that collects the liquid flowing out of the impeller, but also an energy conversion device. When the liquid is thrown from the center of the impeller to the periphery, a low pressure area is formed in the center of the impeller, and the liquid is sucked into the center of the impeller under the action of the total potential energy difference between the liquid level of the storage tank and the center of the impeller. Relying on the continuous operation of the impeller, the liquid is continuously sucked and discharged.

    1. The weight of the pipeline should not be borne on the pump, otherwise the pump will be easily damaged.

      2. The pump and motor are of integral structure. The pump and the motor are an integral structure. It is calibrated by the manufacturer at the time of shipment, so there is no need to adjust the contract when installing it. This makes installation very easy.

      3. The foot bolt must be tightened during installation. The pump should be inspected at regular intervals to prevent it from loosening. To prevent the pump from vibrating violently when starting up and affecting the performance of the pump.

      4. Before installing the pump, check carefully whether there are any hard objects (such as stones, iron sand, etc.) in the flow channel of the pump that may affect the operation of the pump, so as to avoid damaging the overflow parts when the pump is in operation.

      5. For easy maintenance and safety in use. Install a regulating valve on the pump’s throttle and a pressure gauge near the pump’s throttle, and for high head pumps. To prevent water hammer. A check valve should also be installed in front of the outlet gate valve to cope with sudden power failure and other loss of power accidents, thus ensuring that the pump operates under suitable working conditions and increasing the service life of the pump.

      6. The pump is used in suction range situations. It should be equipped with a bottom valve, and the pipeline should not have too many bends in the mouth of the flume, and there should be no water leakage or air leakage in the same inch. To avoid affecting the suction performance of the pump.

      7, in order not to make impurities burst into the pump and block the flow channel to affect the performance. A filter should be installed in front of the pump’s flume.

      8, the installation of pipeline bary for the rotation of the pump rotor parts, should be no grinding sound or jamming phenomenon, otherwise the pump should be disassembled to check the reasons.
