CSG single-suction marine vertical centrifugal pump

Overview

CSG single-suction marine vertical centrifugal pump is a high-efficiency and energy-saving product designed by our company in strict accordance with the international standard ISO2858 and the latest Chinese standard, combining the performance parameters of the IS centrifugal pump and the advantages of the vertical pump structure. It is a new vertical centrifugal pump that replaces conventional products such as IS type horizontal pump and DL type pump.

The flow range of the pump is 1.5 to 1200 cubic meters per hour, and the lift range is 8 to 150 meters. Our company can design and manufacture CSR type hot water pump, CSH type chemical pump, CSB type oil pump and CSBH type explosion-proof chemical pump with the same performance parameters according to different flow medium and temperature.

Features

1. The pump has compact structure, small volume and beautiful appearance. Its vertical structure has a low center of gravity and the center of gravity in the center of the lower half of the pump, which enhances the running stability and life of the pump.

2. Easy to install. The inlet and outlet diameters are the same and are on the same centerline, which can be directly installed in any part of the pipeline like a valve. The motor and rain cover can be used outdoors. The pump is provided with mounting feet for stable installation of the pump.

3. Smooth operation, low noise and high concentricity of components. The motor adopts low-noise bearings, and is equipped with a non-stop refueling device. The pump impeller has excellent dynamic and static balance, no vibration during operation, and improves the use environment.

4. No leakage. The shaft seal adopts corrosion-resistant hard alloy mechanical seal, which solves the problem of serious leakage of the packing seal of the centrifugal pump, prolongs the service life, and ensures the clean and tidy operating site.

5. Easy to maintain. There is no need to disassemble the pipeline, just remove the pump cover nut, take out the rotor and the transmission components for maintenance.

6. The pump can be installed vertically, horizontally or in multiple ways according to the on-site use conditions. According to the flow and lift requirements, the parallel and series methods are adopted to increase the required flow and lift.

Working principle

Before starting the centrifugal pump, the pump casing and the suction pipe should be filled with liquid. After starting the motor, the pump shaft drives the impeller and the liquid to rotate at a high speed. The flow channel flows into the pressurized water line of the pump. At the center of the pump impeller, as the liquid is thrown out under the action of centrifugal force, a vacuum is formed, and the water in the suction pool is pressed into the pump casing under the action of atmospheric pressure, and the impeller rotates continuously to make the liquid in the impeller. Under the action of continuous inflow and outflow, the purpose of transporting liquid is achieved.

 The excellent design of our company's engineers, components made of high-quality materials can extend the life of the pump, reduce the frequency of maintenance, operation stability in complex environments, but it  also cause different prices.

Performance Parameter:

(The following are only the partial parameters. In addition, please provide the parameter of the marine pump you need and we can customize the suitable type for you.)

Precautions for use

1. The maximum working pressure of the pump and the connected pipeline is ≤1.6MPa, and the pressure at the suction port of the pump + the pump head is ≤1.6Mpa. (If the working pressure of the pump system is greater than 1.6MPa, it should be put forward separately when ordering, so that we can use cast steel for the over-current parts and connecting parts of the pump during manufacture).

2. The ambient temperature does not exceed 50°C, the altitude does not exceed 1000 meters, and the relative humidity does not exceed 95%.

3. The conveying medium is clear water or other liquids with similar physical and chemical properties to clear water. (The conveying medium contains fine particles, which should be specified separately when ordering, so that we can assemble the wear-resistant mechanical seal.)

4. Before installing the pump, carefully check whether there are hard objects (such as stones, iron particles, etc.) in the pump flow channel that affect the operation of the pump, so as to avoid damage to the impeller and pump body when the pump is running.

5. The weight of the pipeline should not be added to the pump during installation, and there should be their own support bodies to avoid the deformation of the pump and affect the running performance and life.

6. The anchor bolts must be tightened during installation to avoid the impact of vibration on the pump performance during startup.

7. For the convenience of maintenance and safe use, a regulating valve is installed on the inlet and outlet pipelines of the pump and a pressure gauge is installed near the pump outlet to ensure the operation within the rated head and flow range, to ensure the normal operation of the pump and the growth of the pump. service life of the pump.

8. After installation, turn the pump shaft, the impeller should have no friction noise or stuck phenomenon, otherwise the pump should be disassembled to check the cause.
