Colombia pushing cylinder

(Colombia pushing cylinder,produced by Hebei Hengyu company)

pushing cylinder are widely used in Colombia,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed pushing cylinder for customers from Colombia.

Introduction to pushing cylinder:

When installing the pushing cylinder pipe, the pipe should be cleaned after installation, and should not pass through the pushing cylinder block, and the by-pass pipe must be installed in front of the oil port of the pushing cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the pushing cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the pushing cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

How to determine the working pressure of the pushing cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, pushing cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

pushing cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the pushing cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The quality of the pushing cylinder can not be ignored in the purchase of the pushing cylinder. The pushing cylinder is the main component of the pushing cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. pushing cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of pushing cylinder is deep hole processing, which has always troubled the processing personnel.

Answers to some questions about pushing cylinder:

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.

What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.
