Holland hydraulic cylinder,electric furnace hydraulic cylinder manufacturer,electric furnace hydraulic cylinder
(Holland electric furnace hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
electric furnace hydraulic cylinder are widely used in Holland，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed electric furnace hydraulic cylinder for customers from Holland.
When the electric furnace hydraulic cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the electric furnace hydraulic cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil electric furnace hydraulic cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical electric furnace hydraulic cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the electric furnace hydraulic cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.
Under normal circumstances, the electric furnace hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the electric furnace hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the electric furnace hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the electric furnace hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the electric furnace hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
electric furnace hydraulic cylinder body inspection: The inner surface of the electric furnace hydraulic cylinder and the piston seal are the main factors causing the leakage in the electric furnace hydraulic cylinder, if the electric furnace hydraulic cylinder 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 electric furnace hydraulic cylinder 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.
The difference between the plunger electric furnace hydraulic cylinder and the piston electric furnace hydraulic cylinder is that the piston in the electric furnace hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type electric furnace hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.
How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
Hydraulic cylinder performance requirements?
Hydraulic cylinder performance requirements: hydraulic cylinder is the hydraulic system to achieve energy transfer, conversion and control of the working medium, in addition, it is also responsible for the lubrication of the system, rust prevention, corrosion prevention and cooling. The performance of hydraulic oil will make the system flexible, accurate and reliable. Hydraulic performance requirements are determined according to the design parameters of the hydraulic system, operating conditions, the structure of the hydraulic pump and the working environment. Appropriate viscosity and good viscosion-temperature performance Viscosity is an important performance indicator of hydraulic pressure, which has an important impact on the smooth operation of the hydraulic system and the friction parts. The low temperature performance of hydraulic oil includes three aspects: low temperature flow, low temperature start-up and low temperature pumping.
