Precautions for the Use of Centrifugal Pumps
- In the case of direct connection between the centrifugal pump and the motor, attention should be paid to the concentricity of the centrifugal pump shaft and the output of the motor. The accuracy of the installation of the centrifugal pump has a great influence on the running stability and service life of the pump. It must be installed and calibrated carefully.
- The coupling of the centrifugal pump must be fastened with the nut, and the nut of the centrifugal pump should be locked tightly.
- In order to keep a certain amount of storage liquid in the pump body of the centrifugal pump, in order to achieve better self-priming ability and prevent the dry friction of the mechanical seal, the inlet of the centrifugal pump must be higher than the center line of the pump shaft.
- When the centrifugal pump is installed, the electrostatic grounding resistance of the pump and pipeline should meet its specified requirements.
- When installing the centrifugal pump, strictly check whether there are stones, iron sand and other debris in the pump casing and pipeline.
- Correct the installation clearance and coaxiality of the pump coupling and the motor dynamic coupling, and the allowable deviation of the different coaxiality is 0.1mm. The height difference between the pump shaft and the motor shaft can be adjusted by placing copper or iron sheets on the feet.
- The centrifugal pump should be checked after the actual operation of the unit for 3 to 4 hours. If there is no bad phenomenon, it is deemed that the installation has been completed, and the shaft should be checked during the test run.
- If a one-way valve is installed on the outlet pipeline of the centrifugal pump and the pump cannot discharge the gas smoothly during the self-priming process, an exhaust water pipe and valve should be connected to the outlet of the pump.
Correct application and characteristics of centrifugal pump
Characteristics of centrifugal pump
Centrifugal pump has the characteristics of high-speed ratio, small size, lightweight, high efficiency, large flow, simple structure, drip without a pulse, stable performance, very easy practical operation, and convenient maintenance.
Application of centrifugal pump
Centrifugal pumps are widely used in petrochemical equipment, coal chemical industry, and other chemical industries to deliver different types of liquid and give the working pressure and flow required for chemical changes. There are many types of centrifugal pumps.
According to the different characteristics of the transmission medium, it can be divided into the acid pump, alkali pump, clean water pump, slurry pump, etc. The operating temperature and pressure of the transmission medium are different, so the operating temperature and pressure of the centrifugal pump should be reasonably increased.
The application of cycle time and the reduction of maintenance volume have a great effect on improving the economic benefits of the processing plant.
Selection and installation of centrifugal pump
Centrifugal pumps should be selected according to the liquid conveyed, and the strength should be checked to check the required performance, analyze the suction and discharge standards, and whether they operate intermittently or continuously. Centrifugal pumps should normally operate at or close to the burden and flow standards required by the manufacturer's design scheme. The following follow-up visits shall be carried out during the installation of centrifugal pumps:
①The basic specification, position, and design elevation of the centrifugal pump shall comply with the provisions of the design scheme. The anchor screws must be properly and properly stabilized in the concrete subgrade, and the equipment should not have leakage, damage, or rust;
②According to the characteristics of the medium conveyed by the centrifugal pump, the materials of key parts, shaft hydraulic seals, and gaskets should be checked when necessary;
③The ground leveling and alignment of the centrifugal pump shall meet the requirements of the technical documents of the machine and equipment. If there is no requirement, it shall meet the requirements of the current national industry standard general specification for construction and acceptance of mechanical equipment installation engineering;
④The installation and use of all pipelines and pipes connected with the pump shell of the centrifugal pump and the cleaning regulations of lubricating grease pipelines shall meet the requirements of relevant national industrial standards.
The centrifugal pump needs regular maintenance
- Check whether the pipeline and joint of the centrifugal pump are loose. Turn the centrifugal pump by hand to see if it is flexible.
- Add bearing lubricating oil into the bearing body, observe that the oil level should be at the center line of the oil standard, and the lubricating oil should be replaced or supplemented in time.
- Start the motor. When the centrifugal pump operates normally, open the outlet pressure gauge and the inlet vacuum pump, gradually open the gate valve according to the appropriate pressure, and check the motor load at the same time.
- Try to control the flow and head of the centrifugal pump within the range indicated on the label, to ensure that the centrifugal pump operates at the point, to obtain a large energy-saving effect.
- During the operation of the centrifugal pump, the bearing temperature shall not exceed the ambient temperature of 35C, and the high temperature shall not exceed 80C.
- Within a few months of operation, the lubricating oil of the centrifugal pump is changed after 100 hours, and then every 500 hours.
- Adjust the packing gland frequently to ensure that the leakage in the packing chamber is normal (it is appropriate to leak in drops).
- When the centrifugal pump is used in cold winter, after stopping, unscrew the drain plug at the lower part of the pump body to drain the media to prevent frost cracking.
- If the centrifugal pump is out of service for a long time, it is necessary to disassemble the pump completely, wipe the moisture, coat the rotating parts and joints with grease, and properly protect them.
Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps, i.e. pumps driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables) and a starting protection de
