The basic structure of piston pump usually includes the following parts: 1. Pump body: responsible for fixing all components and bearing pressure. 2. Rotor: It is composed of a plurality of plungers and generates pumping action through rotation. 3. Inlet and outlet valve: a switch used to control the inlet and outlet of liquid. 4. Transmission device: usually a motor or an internal combustion engine, which drives the rotor to rotate. 5. Sealing device: used to keep the pump body airtight and prevent liquid leakage. 6. Oil tank: store the liquid and provide the required liquid to the pump. Different application scenarios and requirements will have different improvements and changes, but these components are the main components of the basic structure of piston pump. In addition to the basic structure, the plunger pump has other structural forms: 1. One-way distribution plunger pump: multiple plungers are arranged in one direction, which can generate higher pressure and is suitable for high-pressure and medium-flow liquid transportation. 2. Bi-directional distribution plunger pump: Two groups of plungers are adopted, which can realize bi-directional transportation by alternately advancing and withdrawing, and can generate higher pressure. 3. Radial piston pump: the plunger moves along the axis of the rotor, which is suitable for high-pressure and low-flow liquid transportation. 4. Swashplate plunger pump: The swash plate is used to push the plunger to move, which can realize large flow and high pressure transportation. 5. Piston pump with slide valve: the movement of the plunger is controlled by the slide valve, which is suitable for conveying liquids with high viscosity or solid particles. The above are the common structural forms of piston pump. Different types of plunger pumps have their own advantages and disadvantages in use scenarios and practical applications, and they need to be selected according to specific conditions. 90R130-DD-5-NN-80-L-4-C8-F-GF-GBA-30-30-24 90R130DD5NN80L4C8FGFGBA303024 90-R-130-DD-5-NN-80-L-4-C8-F-GB-GBA-35-35-24 90R130DD5NN80L4C8FGBGBA353524 90R130-DD-5-NN-80-L-4-C8-F-GB-GBA-35-35-24 90R130DD5NN80L4C8FGBGBA353524 90-R-130-DD-5-NN-80-L-4-C8-F-GB-GBA-32-32-24 90R130DD5NN80L4C8FGBGBA323224 90R130-DD-5-NN-80-L-4-C8-F-GB-GBA-32-32-24 90R130DD5NN80L4C8FGBGBA323224 90-R-130-DD-5-NN-80-L-4-C8-F-GB-GBA-32-32-20 90R130DD5NN80L4C8FGBGBA323220 90-R-130-DD-5-NN-80-L-3-C8-H-GB-GBA-42-42-22 90R130DD5NN80L3C8HGBGBA424222 90R130-DD-5-NN-80-L-3-C8-H-GB-GBA-42-42-22 90R130DD5NN80L3C8HGBGBA424222 90-R-130-DD-5-NN-80-L-3-C8-H-GB-GBA-35-35-24 90R130DD5NN80L3C8HGBGBA353524 90R130-DD-5-NN-80-L-3-C8-H-GB-GBA-35-35-24 90R130DD5NN80L3C8HGBGBA353524 In addition to the above-mentioned piston pump structure, there are some special piston pumps, such as: 1. Diaphragm piston pump: Liquid is transported by diaphragm vibration, which is suitable for transporting volatile or toxic substances. 2. Rotary piston pump: It is composed of a fixed gear and a rotating plunger, and the liquid is conveyed by the plunger extrusion, which is suitable for liquids with high viscosity or solid particles. 3. Multi-cylinder plunger pump: continuous liquid transportation is realized by pushing multiple plungers in turn, which is suitable for the requirements of high flow and high pressure. 4. Air-driven plunger pump: the plunger is driven by compressed air for liquid transportation, which is suitable for occasions where explosion-proof or no power supply is needed. The above are some special piston pump structures, which are widely used in different industries and applications. You can choose a suitable piston pump according to the specific situation. In practical application, the selection of piston pump needs to consider the following factors: 1. Characteristics of conveying fluid: including viscosity, temperature, corrosiveness, etc. 2. Transport flow and pressure requirements: Select the appropriate flow and pressure range according to different occasions and needs. 3. Transportation distance and height: determine the location of the pumping station and the length and height of the pipeline, so as to select the appropriate plunger pump. 4. Space and environment of the pumping station: Select the appropriate piston pump structure according to the space size and environmental requirements of the pumping station, such as noise and vibration requirements. 5. Operating costs: including installation and maintenance costs, energy consumption, accessories costs, etc. In order to meet the actual needs and give full play to its functions, it is necessary to consider the above factors before choosing a suitable piston pump. When using the plunger pump, you should pay attention to the following points: 1. Correct installation and debugging: Install and debug correctly according to the manufacturer's installation instructions to ensure the normal operation of the pumping station. 2. Maintenance: Check and maintain all parts of the pumping station regularly, and replace wearing parts or lubricating oil in time to ensure the long-term stable operation of the equipment. 3. Safe operation: The operator should be familiar with the working principle and safe operation procedures of the plunger pump to ensure the safety during operation. 4. Prevent idling: It is forbidden to idle the plunger pump, otherwise it will damage the plunger and seal and affect the service life of the equipment. 5. Avoid overloading: Avoid overloading the plunger pump, otherwise it may lead to overheating of the equipment and burning out of the motor. 90-R-130-DD-5-CD-80-S-4-C8-H-GB-GBA-42-42-24 90R130DD5CD80S4C8HGBGBA424224 90R130-DD-5-CD-80-S-4-C8-H-GB-GBA-42-42-24 90R130DD5CD80S4C8HGBGBA424224 90-R-130-DD-5-CD-80-L-4-F1-F-GB-GBA-20-20-24 90R130DD5CD80L4F1FGBGBA202024 90R130-DD-5-CD-80-L-4-F1-F-GB-GBA-20-20-24 90R130DD5CD80L4F1FGBGBA202024 90-R-130-DD-5-CD-80-L-4-C8-H-G8-GBA-26-26-20 90R130DD5CD80L4C8HG8GBA262620 90R130-DD-5-CD-80-L-4-C8-H-G8-GBA-26-26-20 90R130DD5CD80L4C8HG8GBA262620 90-R-130-DD-5-CD-80-L-3-C8-H-GB-GBA-35-35-24 90R130DD5CD80L3C8HGBGBA353524 90R130-DD-5-CD-80-L-3-C8-H-GB-GBA-35-35-24 90R130DD5CD80L3C8HGBGBA353524 90-R-130-DD-5-CD-80-L-3-C8-H-GB-GBA-23-23-24 90R130DD5CD80L3C8HGBGBA232324 90R130-DD-5-CD-80-L-3-C8-H-GB-GBA-23-23-24 90R130DD5CD80L3C8HGBGBA232324 These precautions must be observed when using piston pump. Only by fully understanding and strictly observing these requirements can we ensure the normal operation of the equipment and extend its service life. In the maintenance of piston pump, some common problems and solutions are as follows: 1. Leakage: There may be many reasons for leakage, such as abrasion and looseness of seals. It is necessary to inspect the pump station, determine the cause of leakage and replace the corresponding components. 2. Excessive noise: The noise of the plunger pump is too high, which may be due to bearing damage or improper installation. Need to check and repair the equipment. 3. Flow reduction or stop: It may be due to the blockage of suction pipe or the damage of internal components of pump body. The blockage can be cleaned or the corresponding components can be replaced. 4. The motor does not turn or the steering is difficult: it may be due to motor damage or power failure. Need to check and repair the motor and power supply. 5. Excessive temperature: It may be due to overheating of liquid or excessive load of pumping station. It is necessary to lower the liquid temperature or adjust the load of the pumping station. These problems and solutions are common in the daily maintenance of piston pump, which need to be analyzed and dealt with according to the specific situation and actual problems. At the same time, it is necessary to pay attention to safe operation in maintenance to ensure personal and equipment safety.
