The total reciprocating stroke of piston pump plunger is fixed, which is determined by the structure of piston pump. The plunger pump reciprocates in the pump body through the plunger, sucking the liquid into the pump body and compressing and conveying it. Each reciprocating cycle includes three stages: feeding, compressing and discharging. The total stroke of the plunger of a piston pump generally depends on the diameter of the plunger and the length of the inner cavity of the pump, and will not change during normal use. Therefore, in practical application, we can choose the appropriate specifications and models of piston pump according to the process requirements and pump head pressure to meet the production requirements. In addition to the fixed total reciprocating stroke of the plunger of the plunger pump, there are other factors that will also affect the performance and use effect of the plunger pump, including: 1. Liquid characteristics: The liquid used in the plunger pump should meet its specified properties and requirements, such as temperature, viscosity, solid particle content, etc. Otherwise, the performance of the pump will be affected. 2. Operating environment: The temperature, humidity, air pressure and other factors of the environment should be paid attention to during the operation of the pumping station to ensure the normal operation of the pump. 3. Maintenance: Regular maintenance of all parts of the plunger pump to keep it clean and in good condition is helpful to prolong the service life of the pump and improve its stability. 4. Selection of accessories: When using a plunger pump, it is also very important to choose appropriate accessories, such as valves, pipes, connectors, filters, etc. The selection of these accessories should match the specifications and models of the plunger pump, and have the characteristics of corrosion resistance and sealing. 90-R-130-DC-1-CD-80-L-3-F1-H-GB-GBA-35-35-24 90R130DC1CD80L3F1HGBGBA353524 90-R-130-DC-1-BC-80-S-3-F1-H-G1-GBA-32-35-30 90R130DC1BC80S3F1HG1GBA323530 90R130-DC-1-BC-80-S-3-F1-H-G1-GBA-32-35-30 90R130DC1BC80S3F1HG1GBA323530 90-R-130-DC-1-BC-80-S-3-F1-H-G1-GBA-30-35-30 90R130DC1BC80S3F1HG1GBA303530 90R130-DC-1-BC-80-S-3-F1-H-G1-GBA-30-35-30 90R130DC1BC80S3F1HG1GBA303530 90-R-100-MS-5-BC-80-S-4-C7-F-C5-GBA-17-17-20 90R100MS5BC80S4C7FC5GBA171720 90R100-MS-5-BC-80-S-4-C7-F-C5-GBA-17-17-20 90R100MS5BC80S4C7FC5GBA171720 90-R-100-MS-5-BB-80-P-3-F1-F-C5-GBA-42-42-24 90R100MS5BB80P3F1FC5GBA424224 90R100-MS-5-BB-80-P-3-F1-F-C5-GBA-42-42-24 90R100MS5BB80P3F1FC5GBA424224 90-R-100-MS-1-NN-60-S-3-C7-E-03-GBA-26-26-20 90R100MS1NN60S3C7E03GBA262620 In addition, the following points should be noted in the use of piston pump: 1. The plunger pump should be stable during operation to avoid frequent start-stop or overload operation. If it is necessary to adjust the flow or pressure, it can be achieved by adjusting the valve and changing the pump speed. 2. For the piston pump that is not used for a long time, it needs to be inspected and maintained before starting to ensure its normal operation. At the same time, when the use interval is long, it is also necessary to start the machine regularly to prevent the liquid in the pump from drying or depositing. 3. After the plunger pump is stopped, the liquid in the pump should be drained as much as possible, and it should be cleaned, maintained and maintained to prevent the pump internals from being damaged or corroded. In addition, the plunger pump should be placed in a ventilated and dry place to avoid moisture or dust affecting the normal use of the pump. 4. When using the plunger pump, you should pay attention to safety measures, abide by relevant operating procedures and precautions, such as wearing protective glasses and gloves, to avoid accidents. In addition, the piston pump is widely used, often used in chemical industry, petroleum industry, pharmaceutical industry, food industry, etc. For different applications and material conveying requirements, there are also different piston pump types to choose from. For example, for high-viscosity materials or materials containing large particles, a swash plate piston pump with small flow, high pressure, corrosion resistance and good pressure regulation can be selected; For pure materials or volatile materials, you can choose a diaphragm piston pump with non-toxic, tasteless and good sealing. In addition, there are some special piston pump types, such as sandwich piston pump, heat insulation piston pump, high-pressure piston pump, etc., which can meet the needs of different industries and different fluid transportation. 90-R-100-MS-1-CD-80-S-3-C7-E-03-GBA-35-35-30 90R100MS1CD80S3C7E03GBA353530 90R100-MS-1-CD-80-S-3-C7-E-03-GBA-35-35-30 90R100MS1CD80S3C7E03GBA353530 90-R-100-MA-5-NN-80-S-4-S1-E-C5-GBA-21-21-24 90R100MA5NN80S4S1EC5GBA212124 90R100-MA-5-NN-80-S-4-S1-E-C5-GBA-21-21-24 90R100MA5NN80S4S1EC5GBA212124 90-R-100-MA-5-NN-80-S-4-C7-E-C5-GBA-26-26-24 90R100MA5NN80S4C7EC5GBA262624 90R100-MA-5-NN-80-S-4-C7-E-C5-GBA-26-26-24 90R100MA5NN80S4C7EC5GBA262624 90-R-100-MA-5-NN-80-S-3-S1-F-C5-GBA-35-35-30 90R100MA5NN80S3S1FC5GBA353530 90R100-MA-5-NN-80-S-3-S1-F-C5-GBA-35-35-30 90R100MA5NN80S3S1FC5GBA353530 90-R-100-MA-5-NN-80-S-3-S1-E-C5-GBA-42-42-24 90R100MA5NN80S3S1EC5GBA424224 90R100-MA-5-NN-80-S-3-S1-E-C5-GBA-42-42-24 90R100MA5NN80S3S1EC5GBA424224 In addition to the above-mentioned precautions in use and maintenance, there are some common piston pump failures and solutions, as follows: 1. Leakage problem: The leakage problem of the plunger pump during operation may be caused by aging, wear or looseness of the seal. The solution can be to replace the seal, tighten the fastening bolts or adjust the surface fit of the pump body. 2. Noise problem: The noise generated by the plunger pump during operation may be caused by improper clearance between the plunger and the pump body, damage to the impeller of the plunger pump or deformation of the pump body. The solution can be to recast the pump, repair or replace the pump impeller. 3. Vibration of the pump body: The piston pump generates excessive vibration during operation, which may affect its normal work and life. One of the reasons is the poor matching between the plunger and the pump body or the imbalance of the plunger spring. The solution is to carry out matching testing, adjustment or replacement of the plunger. 4. Abnormal flow or pressure: Abnormal flow or pressure of plunger pump during operation may be caused by pipeline blockage, plunger wear, poor seal of pump body or valve failure. The solution can be to clean the pipeline, replace the plunger, repair the seal or replace the valve. In a word, all kinds of faults will inevitably occur in the use of piston pump, which need to be found and solved in time to ensure its normal and efficient operation. At the same time, special attention should be paid to safety matters when operating and maintaining the piston pump to ensure the safety of personnel and equipment.
