Replacing copper sleeve is a common way to install piston pump cylinder. In the process of using a plunger pump, the sealing between the piston and the cylinder block is required to be high. Once it is used frequently, the cylinder liner will be worn, which will affect the performance of the plunger pump. At this time, the cylinder liner needs to be replaced to ensure the continuous and stable operation of the piston pump. The steps for replacing the copper sleeve are as follows: 1. Dismantle the plunger pump first and clean the original cylinder liner. 2. Install the new copper sleeve into the cylinder body, and pay attention to adjust its position and direction. During installation, make sure that the surface of the copper sleeve is smooth and uniform, and it is well matched with the plunger. 3. Reinsert the plunger into the cylinder body and check whether its position matches the copper sleeve. When inserting the plunger, a small amount of lubricating oil should be applied to ensure the smooth movement of the plunger. 4. After installing the cylinder block, conduct other assembly work of the plunger pump, and test whether the performance of the plunger pump is normal. 90-R-130-HF-1-BC-80-R-4-F1-H-04-GBA-35-35-24 90R130HF1BC80R4F1H04GBA353524 90R130-HF-1-BC-80-R-4-F1-H-04-GBA-35-35-24 90R130HF1BC80R4F1H04GBA353524 90-R-130-HF-1-BC-80-R-4-F1-H-00-GBA-32-32-24 90R130HF1BC80R4F1H00GBA323224 90R130-HF-1-BC-80-R-4-F1-H-00-GBA-32-32-24 90R130HF1BC80R4F1H00GBA323224 90R130-HF-1-BC-80-P-3-F1-H-03-GBA-35-35-24 90R130HF1BC80P3F1H03GBA353524 90-R-130-HF-1-BC-80-L-4-C8-H-03-GBA-26-26-24 90R130HF1BC80L4C8H03GBA262624 90R130-HF-1-BC-80-L-4-C8-H-03-GBA-26-26-24 90R130HF1BC80L4C8H03GBA262624 90-R-130-DD-5-NN-80-S-4-C8-F-GB-GBA-32-32-24 90R130DD5NN80S4C8FGBGBA323224 90R130-DD-5-NN-80-S-4-C8-F-GB-GBA-32-32-24 90R130DD5NN80S4C8FGBGBA323224 90-R-130-DD-5-NN-80-S-3-F1-F-GB-GBA-38-38-24 90R130DD5NN80S3F1FGBGBA383824 It should be noted that when replacing the copper sleeve, it is necessary to operate according to the relevant standards and specifications to ensure the quality and service life of the copper sleeve. At the same time, when replacing the copper sleeve, we should also pay attention to safety measures, such as wearing protective gloves and glasses. In addition, besides replacing the copper sleeve, there are other ways to install the piston pump cylinder block, such as directly processing the cylinder liner and forging the cylinder block. Different installation methods have their own advantages and disadvantages, which need to be selected according to the specific situation. Direct processing of cylinder liner is to process the cylinder block of piston pump into the cylinder liner shape with matching inner diameter and plunger, and polish the surface. Although the processing cost is high, this method can improve the sealing and matching between the cylinder liner and the plunger, thus improving the working efficiency of the plunger pump. Forging cylinder block is to forge the whole cylinder block into a whole by forging process, thus eliminating the matching problem between cylinder liner and plunger. At the same time, the forged cylinder block also has excellent strength and durability, and can withstand the requirements of environmental conditions such as high pressure and high temperature. However, the forging cost is high, which is not suitable for small batch production and customization. When choosing the installation method of piston pump cylinder, it is necessary to comprehensively consider various factors, including production cost, service life, performance requirements, etc., in order to choose the most suitable scheme. At the same time, attention should be paid to relevant safety measures during installation to ensure that no safety accidents occur during operation. In addition to the installation mode of cylinder block, the selection of suitable materials also has a great influence on the performance and life of piston pump cylinder block. Common piston pump cylinder materials include cast iron, cast steel and stainless steel. Cast iron is one of the commonly used materials for piston pump, which has the characteristics of low price and easy processing. However, cast iron has low density, relatively low strength and hardness, and is prone to defects such as porosity, so its service life is not long enough. Cast steel and stainless steel are two kinds of high-quality materials, which have the characteristics of high density, high strength and hardness, corrosion resistance and so on, and are suitable for working under high pressure and high temperature conditions. Among them, stainless steel has better corrosion resistance, which can better protect the surface of piston pump cylinder and reduce wear and corrosion. When selecting materials, it is necessary to select them according to actual needs, and evaluate and test them in combination with relevant standards and specifications. At the same time, it is necessary to pay attention to maintenance during the use of piston pump cylinder, and timely detect and replace damaged or aging parts to ensure the normal work of piston pump. In addition, in order to ensure its stable performance, safety and reliability, some details need to be considered in the design and manufacture of piston pump cylinder. For example, when designing the cylinder block, it is necessary to consider the fit clearance between the plunger and the cylinder block, and improve the matching between the plunger and the cylinder block through polishing and other processing technologies. At the same time, it is necessary to set oil passages and sealing rings inside the cylinder body to ensure the smooth flow of oil and prevent leakage. In the manufacturing process, strict inspection and quality control should be carried out to ensure that the size, shape and surface quality of the cylinder body meet the relevant standards and specifications, so as to ensure the performance and use effect of the piston pump. In addition, the piston pump cylinder should be properly maintained, the damaged parts should be replaced in time during use, and the piston pump should be tested and cleaned regularly to prolong its service life. 90R130-DD-5-NN-80-S-3-F1-F-GB-GBA-38-38-24 90R130DD5NN80S3F1FGBGBA383824 90-R-130-DD-5-NN-80-S-3-C8-H-GB-GBA-42-42-24 90R130DD5NN80S3C8HGBGBA424224 90R130-DD-5-NN-80-S-3-C8-H-GB-GBA-42-42-24 90R130DD5NN80S3C8HGBGBA424224 90-R-130-DD-5-NN-80-S-3-C8-H-GB-GBA-35-35-24 90R130DD5NN80S3C8HGBGBA353524 90R130-DD-5-NN-80-S-3-C8-H-GB-GBA-35-35-24 90R130DD5NN80S3C8HGBGBA353524 90-R-130-DD-5-NN-80-S-3-C8-F-GB-GBA-42-42-24 90R130DD5NN80S3C8FGBGBA424224 90R130-DD-5-NN-80-S-3-C8-F-GB-GBA-42-42-24 90R130DD5NN80S3C8FGBGBA424224 90-R-130-DD-5-NN-80-R-4-C8-H-GB-GBA-32-32-24 90R130DD5NN80R4C8HGBGBA323224 90R130-DD-5-NN-80-R-4-C8-H-GB-GBA-32-32-24 90R130DD5NN80R4C8HGBGBA323224 90-R-130-DD-5-NN-80-L-4-C8-F-GF-GBA-30-30-24 90R130DD5NN80L4C8FGFGBA303024 For the maintenance of piston pump cylinder, besides regular inspection and replacement of damaged parts, the following points should be noted: 1. Keep it clean: The piston pump cylinder body is easily polluted by dust and impurities during use, so it needs to be cleaned regularly to prevent these impurities from entering the piston pump and affecting work efficiency. 2. Keep lubrication: the plunger in the piston pump cylinder needs to run smoothly in the cylinder and generate certain friction, so the selection and filling of lubricating oil is very important. If the lubrication is insufficient or the lubricating oil is not suitable, it will lead to increased friction and increased wear, thus affecting the working effect and life of the piston pump. 3. Keep the seal: The hydraulic system inside the piston pump cylinder needs to keep a good sealing performance, otherwise it is prone to problems such as oil leakage and pressure drop. Therefore, it is necessary to replace aging and damaged sealing rings, O-rings and other parts in time, and conduct regular inspection and maintenance. 4. Maintain safety: In case of high pressure and high temperature generated by piston pump cylinder during work, safety measures should be taken to avoid accidents. Wear protective gloves, goggles and other personal protective equipment during use, and ensure that the installation, debugging and maintenance of the plunger pump meet the relevant operating specifications and requirements. In a word, the piston pump cylinder is the core component of the piston pump. In order to ensure the performance, safety and reliability of the piston pump, it is necessary to pay attention to all kinds of details, and carry out regular inspection and maintenance during use to prolong the service life.
