The most important parts of plunger pump are plunger and plunger kit. Plunger and plunger kit are the core components of plunger pump, which are responsible for generating high-pressure fluid and completing the transportation task. Plunger is usually made of hard metal material, which is wear-resistant and corrosion-resistant, and can withstand extreme conditions such as high pressure and high temperature. The plunger set is used to fix the plunger, and a continuous closed working chamber is formed between the plunger and the pump body through the sealing structure to ensure that the fluid is compressed and pumped out of the pump. Of course, the bearing is also a very important component in the piston pump, its main function is to support the rotor, reduce friction resistance and energy loss, and ensure the stable operation and life of the pump. However, in the plunger pump, the plunger and plunger kit are the most important components, which are directly related to the pressure, flow rate and service life of the pump. In addition, other important components of the plunger pump include: 1. Pump body: usually made of castings or forgings, its internal cavity, plunger and plunger kit form a continuous closed space, and the pump body shell is provided with a feed inlet and a discharge outlet, and relevant valves and pipelines are configured to complete the fluid transportation. 2. Driving device: Piston pumps usually need motors, hydraulic motors and other driving devices to realize the reciprocating motion of the plunger and support the normal operation of the pump. 3. Ductile iron: Ductile iron is a common material used for piston pump base and other parts. It has the advantages of high strength, high toughness and wear resistance, and can withstand large loads and vibrations. 4. Discharge valve: The discharge valve is a key component installed at the outlet of the plunger pump, and its main function is to keep the pressure in the plunger and prevent backflow and leakage when the pump stops working. 90-R-130-DD-5-BC-80-S-3-F1-H-GB-GBA-35-35-28 90R130DD5BC80S3F1HGBGBA353528 90R130-DD-5-BC-80-S-3-F1-H-GB-GBA-35-35-28 90R130DD5BC80S3F1HGBGBA353528 90-R-130-DD-5-BC-80-L-4-C8-H-GB-GBA-42-42-28 90R130DD5BC80L4C8HGBGBA424228 90R130-DD-5-BC-80-L-4-C8-H-GB-GBA-42-42-28 90R130DD5BC80L4C8HGBGBA424228 90-R-130-DD-5-BB-80-S-3-F1-H-GB-GBA-35-35-22 90R130DD5BB80S3F1HGBGBA353522 90R130-DD-5-BB-80-S-3-F1-H-GB-GBA-35-35-22 90R130DD5BB80S3F1HGBGBA353522 90-R-130-DD-5-AB-80-S-4-F1-H-G8-GBA-42-42-24 90R130DD5AB80S4F1HG8GBA424224 90R130-DD-5-AB-80-S-4-F1-H-G8-GBA-42-42-24 90R130DD5AB80S4F1HG8GBA424224 90-R-130-DD-5-AB-80-S-4-C8-F-GF-GBA-17-17-20 90R130DD5AB80S4C8FGFGBA171720 90R130-DD-5-AB-80-S-4-C8-F-GF-GBA-17-17-20 90R130DD5AB80S4C8FGFGBA171720 In addition, the plunger pump has some important technical parameters and performance indicators, as follows: 1. Flow: The flow of plunger pump refers to the volume of fluid passing through the pump body in unit time, usually expressed as liters per minute. The flow rate is directly related to the working efficiency and application scope of piston pump. 2. Pressure: The pressure of plunger pump refers to the pressure generated by the fluid in the pump body, usually expressed as Pascal (Pa) or Bar. The pressure directly affects the parameters such as conveying distance and conveying height of piston pump. 3. Rotational speed: The rotational speed of the plunger pump refers to the rotational speed generated by the driving device, which is usually expressed as revolutions per minute. The rotational speed will have an impact on the flow and pressure of the pump. 4. Efficiency: The efficiency of piston pump refers to the ratio of output power to input power, and its value is usually between 0.5 and 0.9. Efficiency affects the energy consumption and operating cost of piston pump. 5. Characteristic curve: The characteristic curve of plunger pump refers to the pressure or power change of plunger pump under different flow conditions. Characteristic curve is one of the important bases to evaluate the performance of piston pump, which can help users choose the piston pump that suits their own needs. In addition, the piston pump has a wide range of applications, and the common application fields include: 1. Petrochemical: Piston pumps can be used to transport various liquids and gases, such as petroleum and chemical raw materials, and are suitable for chemical production, oil pipelines, offshore drilling platforms and other industries. 2. Environmental protection water treatment: the plunger pump can be used for environmental protection projects such as sewage treatment, water supply circulation and sludge transportation, and has the characteristics of high pressure and stable flow. Food and medicine: Piston pump can transport all kinds of food and medical products, and is widely used in food processing, pharmaceutical and other industries. 4. Paper-making and printing: The plunger pump can transport various liquids such as slurry, ink and ink, and it is one of the important equipments in the paper-making and printing industry. 5. Energy and electricity: Piston pumps can be used to transport coal slurry, light oil and other energy products, and play an important role in power plants, thermal power stations and other fields. 90-R-130-DD-5-AB-80-S-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80S4C8FGBGBA424224 90R130-DD-5-AB-80-S-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80S4C8FGBGBA424224 90-R-130-DD-5-AB-80-P-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80P4C8FGBGBA424224 90R130-DD-5-AB-80-P-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80P4C8FGBGBA424224 90-R-130-DD-2-NN-80-R-7-F1-F-GB-GBA-30-30-28 90R130DD2NN80R7F1FGBGBA303028 90R130-DD-2-NN-80-R-7-F1-F-GB-GBA-30-30-28 90R130DD2NN80R7F1FGBGBA303028 90-R-130-DD-1-BC-80-P-4-F1-H-G8-GBA-35-35-24 90R130DD1BC80P4F1HG8GBA353524 90R130-DD-1-BC-80-P-4-F1-H-G8-GBA-35-35-24 90R130DD1BC80P4F1HG8GBA353524 90-R-130-DC-1-DE-80-S-3-C8-H-G1-GBA-30-35-30 90R130DC1DE80S3C8HG1GBA303530 90R130-DC-1-DE-80-S-3-C8-H-G1-GBA-30-35-30 90R130DC1DE80S3C8HG1GBA303530 When using the plunger pump, you should also pay attention to the following points: 1.
