(cylinder of the plate rolling machine,produced by Hengyu Hydraulic Cylinder Factory）

cylinder of the plate rolling machine are widely used ，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed cylinder of the plate rolling machine for our customers.

Introduction to cylinder of the plate rolling machine:

cylinder of the plate rolling machine body inspection: The inner surface of the cylinder of the plate rolling machine and the piston seal are the main factors causing the leakage in the cylinder of the plate rolling machine, if the cylinder of the plate rolling machine has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the cylinder of the plate rolling machine mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

When the initial action of the cylinder of the plate rolling machine is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the cylinder of the plate rolling machine. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

When the cylinder of the plate rolling machine thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the cylinder of the plate rolling machine. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the cylinder of the plate rolling machine still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

When the cylinder of the plate rolling machine needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the cylinder of the plate rolling machine, and hard beating and sudden drop are strictly prohibited during disassembly.

Answers to some questions about cylinder of the plate rolling machine:

Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.

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.
