Uganda hydraulic jig cylinder

(Uganda hydraulic jig cylinder,produced by Hengyu Group)

hydraulic jig cylinder are widely used in Uganda,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed hydraulic jig cylinder for customers from Uganda.

Introduction to hydraulic jig cylinder:

The daily inspection of the hydraulic jig cylinder includes: checking the connection of the hydraulic jig cylinder and the pipe joint for leaks. Check the hydraulic jig cylinder rod for leaks. Check the hydraulic jig cylinder connection for leaks. When the hydraulic jig cylinder moves, the work is normal and smooth. Whether the hydraulic jig cylinder has internal leakage.

hydraulic jig cylinder is the most important part of construction machinery, the traditional processing method is: broaching hydraulic jig cylinder block - fine boring hydraulic jig cylinder block - grinding hydraulic jig cylinder block. The rolling method is: broaching hydraulic jig cylinder block - fine boring hydraulic jig cylinder block - rolling hydraulic jig cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the hydraulic jig cylinder block is about 1-2 days, rolling 1 meter of the hydraulic jig cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the hydraulic jig cylinder increases by 25%. If the hydraulic jig cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality hydraulic jig cylinders, you must take the rolling production process. After the hydraulic jig cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

We can not just consider the price and ignore the quality when we purchase the hydraulic jig cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the hydraulic jig cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the hydraulic jig cylinder is not required.

The machining accuracy of the hydraulic jig cylinder depends on the level of equipment, production technology and testing means. hydraulic jig cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Answers to some questions about hydraulic jig cylinder:

How to distinguish the bucket cylinder from the bucket rod cylinder?
It can be distinguished according to its installation and connection: one end of the bucket cylinder is connected with the bucket; The rod cylinder is not connected to the bucket. The bucket refers to the bucket installed on the excavator. According to the working mode, it is divided into backhoe bucket and shovel bucket, the backhoe bucket is commonly used. The boom and bucket rod are working device of the excavator, usually called the big arm and the forearm, which are mainly used to control the digging and loading of the bucket. The arm connected to the frame is longer, so it is commonly known as the big arm, and its term is called the boom. The arms connected to the digging bucket are smaller, so they are commonly known as the lower arms, and the term is called the bucket rod, so they are commonly known as the big lower arms.

Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
