Piston pump usually consists of four parts: sub-pump, oil quantity adjusting mechanism, transmission mechanism and pump body. 1. Sub-pump: The sub-pump of piston pump usually adopts multi-head plunger structure, and each pump head has independent suction and discharge ports, which can transport liquid to different positions respectively. 2. Oil quantity regulating mechanism: The oil quantity regulating mechanism of piston pump usually includes adjustable inching control valve and manual regulating valve. These mechanisms can accurately control the flow and pressure of pumping stations to meet different occasions and needs. 3. Transmission mechanism: The transmission mechanism of plunger pump usually includes motor, reducer and coupling, which can convert electric energy into mechanical energy and drive the movement of plunger. 4. Pump body: The pump body of a plunger pump is usually composed of pump shell, plunger, seal and other parts. Among them, the plunger and seal are responsible for the suction and discharge of liquid, while the pump housing protects and fixes the plunger and seal, and at the same time plays a sealing role in the pumping station. These parts are connected with each other to form a complete piston pump system, which realizes the transportation and adjustment of liquid. In practical application, these components can be optimized according to specific occasions and needs to better adapt to different working conditions and environments. In the application of piston pump, according to different working requirements and application scenarios, different types of piston pumps can be used, mainly including the following: 90-R-100-MA-5-NN-80-S-3-S1-E-C5-GBA-26-26-28 90R100MA5NN80S3S1EC5GBA262628 90R100-MA-5-NN-80-S-3-S1-E-C5-GBA-26-26-28 90R100MA5NN80S3S1EC5GBA262628 90-R-100-MA-5-NN-80-S-3-S1-E-C5-GBA-20-20-24 90R100MA5NN80S3S1EC5GBA202024 90R100-MA-5-NN-80-S-3-S1-E-C5-GBA-20-20-24 90R100MA5NN80S3S1EC5GBA202024 90-R-100-MA-5-NN-80-S-3-C7-E-C5-GBA-42-42-24 90R100MA5NN80S3C7EC5GBA424224 90R100-MA-5-NN-80-S-3-C7-E-C5-GBA-42-42-24 90R100MA5NN80S3C7EC5GBA424224 90-R-100-MA-5-NN-80-S-3-C7-E-C5-GBA-38-38-24 90R100MA5NN80S3C7EC5GBA383824 90R100-MA-5-NN-80-S-3-C7-E-C5-GBA-38-38-24 90R100MA5NN80S3C7EC5GBA383824 90-R-100-MA-5-NN-80-S-3-C7-E-C5-GBA-35-35-24 90R100MA5NN80S3C7EC5GBA353524 90R100-MA-5-NN-80-S-3-C7-E-C5-GBA-35-35-24 90R100MA5NN80S3C7EC5GBA353524 1. Piston plunger pump: Piston plunger pump refers to the suction and discharge of liquid through piston movement. It is simple in structure and reliable in operation, but the accuracy of flow and pressure adjustment is relatively low, so it is often used in some industrial and civil applications with low requirements on transportation capacity and pressure. 2. Multi-head plunger pump: Multi-head plunger pump refers to sucking and discharging through multiple plungers respectively, so as to realize large-flow and high-pressure liquid transportation. Its adjustment accuracy is relatively high, and it is often used in industrial and agricultural applications with high pressure and high flow requirements. 3. Gear pump plunger combination pump: Gear pump plunger combination pump usually consists of gear pump and plunger pump to realize high flow and high pressure transportation. It has compact structure, high power density and high efficiency, and is widely used in building materials, excavation machinery, mining machinery and other fields. 4. Hydraulic piston pump: The hydraulic piston pump controls the pumping station by adjusting the system pressure and flow, which is suitable for some industrial automation applications with high dynamic response and high requirements. Different types of plunger pumps have their own characteristics, advantages and disadvantages, and they need to be comprehensively considered and reasonably matched according to specific needs when choosing. In the practical application of piston pump, due to its characteristics and advantages, it is widely used in various industrial, agricultural and civil fields, mainly including the following aspects: 1. Water pump station: The plunger pump can transport liquid with large flow and high pressure, which is suitable for some areas and projects that need a lot of water, such as urban water supply and irrigation. 2. Mining machinery: Piston pumps are often used in mining machinery, such as tunnel boring machines and mine hoists. 3. Building materials: The plunger pump can transport all kinds of building materials to the construction site, such as concrete, mortar and paint. 4. Hydraulic machinery: As the core component of hydraulic system, piston pump is widely used in various hydraulic equipment, such as excavators, loaders and bulldozers. 5. Food processing: Piston pumps can ensure accurate flow and pressure control, and are widely used in food processing industries, such as beverage production, dairy production and jam production. In addition to the application field, the performance parameters of piston pump are also important factors to be considered when selecting. Mainly includes the following points: 1. Flow: The flow of plunger pump refers to the volume of liquid flowing through the pump body in unit time. Different types of plunger pumps have different flow ranges and need to be selected according to specific needs. 2. Head: The head of the plunger pump refers to the pressure that can be generated when the pump station transports liquid, that is, the height difference between the inlet and the outlet of the transported liquid. Generally speaking, the higher the lift, the greater the pressure of the pump. 3. Pressure: The pressure of plunger pump refers to the maximum pressure that can be generated when the pumping station works. Generally speaking, the greater the pressure, the farther the pump station will transport liquid. 4. Efficiency: The efficiency of the plunger pump refers to the ratio of the energy that can be used in the pumping station to the total energy. Generally speaking, the higher the efficiency, the lower the energy consumption of the pumping station, saving energy. 5. Temperature rise: The temperature rise of piston pump refers to the heat generated by friction and other reasons when the pump station transports liquid. Generally speaking, the lower the temperature rise, the smaller the heat loss of the pumping station. 90-R-100-MA-5-NN-80-R-4-S1-F-C5-GBA-20-20-30 90R100MA5NN80R4S1FC5GBA202030 90R100-MA-5-NN-80-R-4-S1-F-C5-GBA-20-20-30 90R100MA5NN80R4S1FC5GBA202030 90-R-100-MA-5-NN-80-R-4-C7-E-C5-GBA-32-32-30 90R100MA5NN80R4C7EC5GBA323230 90R100-MA-5-NN-80-R-4-C7-E-C5-GBA-32-32-30 90R100MA5NN80R4C7EC5GBA323230 90-R-100-MA-5-NN-80-P-3-S1-F-C5-GBA-42-42-24 90R100MA5NN80P3S1FC5GBA424224 90R100-MA-5-NN-80-P-3-S1-F-C5-GBA-42-42-24 90R100MA5NN80P3S1FC5GBA424224 90-R-100-MA-5-NN-80-P-3-C7-D-C5-GBA-32-32-24 90R100MA5NN80P3C7DC5GBA323224 90R100-MA-5-NN-80-P-3-C7-D-C5-GBA-32-32-24 90R100MA5NN80P3C7DC5GBA323224 90-R-100-MA-5-NN-80-L-4-F1-E-C5-GBA-23-23-24 90R100MA5NN80L4F1EC5GBA232324 90R100-MA-5-NN-80-L-4-F1-E-C5-GBA-23-23-24 90R100MA5NN80L4F1EC5GBA232324 For the selection and use of plunger pump, the following points should be noted: 1. The installation position of the plunger pump should be selected in a dry, ventilated and vibration-free place, and the connection with the conveying pipeline should be tight and reliable. 2. Before using the plunger pump, it should be inspected and maintained to ensure the integrity and sealing of the pump body and components. In addition, it is necessary to select a suitable motor or engine according to the transmission mode to ensure normal operation. 3. During use, the pump should be operated in strict accordance with the specified flow, lift and pressure, and overload or frequent start-stop should be avoided to prolong the service life of the pump. 4. Maintain the plunger pump regularly, including cleaning, replacing lubricating oil, checking seals, etc., to ensure the normal operation and stability of the pump body and components. 5. When the plunger pump is closed, in order to prevent unnecessary damage and accidents, it is necessary to cut off the power supply or remove the connecting pipe during the downtime. In a word, piston pump plays an important role in practical application, but its selection and use need careful consideration and careful operation to ensure safety and effectiveness.
