Italy hydraulic cylinder,push bench hydraulic cylinder manufacturer,push bench hydraulic cylinder(Italy push bench hydraulic cylinder,produced by Hengyu Group)
push bench hydraulic cylinder are widely used in Italy,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed push bench hydraulic cylinder for customers from Italy.
When the push bench hydraulic cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the push bench hydraulic cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.
The push bench hydraulic cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
The piston rod and guide sleeve function of the push bench hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.
When installing the push bench hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the push bench hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the push bench hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the push bench hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the push bench hydraulic 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.
Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.
Why does the tipping bucket cylinder have a cylinder withdrawal problem?
This problem may have a certain relationship with the operation of the driver, the main reasons are the following two situation analysis: 1, the current domestic loader working device is mostly a six-link mechanism, the six-link mechanism in the bucket to the limit position, lift the boom, the rotating bucket cylinder will appear "cylinder pulling" phenomenon, that is, the piston rod of the rotating bucket cylinder will be pulled out. In this case, in order to protect the cylinder, a pressure overload protection valve with large and small cavities is provided on the multi-way valve rotating bucket link (large chamber 18MPa, small chamber 12MPa). 2, before the cylinder is assembled to the whole machine, the cylinder is not limited, the piston rod of the cylinder can be pulled in place before and after, but when it is installed on the whole machine, in order to avoid the cylinder pulling out, the limit switch is installed according to the regulations.
