UAE hydraulic cylinder,steering cylinder manufacturer,steering cylinder
(UAE steering cylinder,produced by Hengyu Hydraulic Co., Ltd）
steering cylinder are widely used in UAE，because of long service life，smooth movement，high work efficiency.So our company has designed steering cylinder for customers from UAE.
The quality of the steering cylinder can not be ignored in the purchase of the steering cylinder. The steering cylinder is the main component of the steering 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. steering 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 steering cylinder is deep hole processing, which has always troubled the processing personnel.
Protection of the steering cylinder surface: During the dismantling process, safety protection should be carried out on the steering cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the steering cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the steering cylinder should be cleaned up in time.
The cavitation of the steering cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the steering cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
When the steering cylinder 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 steering cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the steering cylinder 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.
What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.
How to use a solenoid valve to control the expansion of a cylinder? Doesn't the solenoid valve only control on/off?
Use the solenoid valve P into A-B (generally equipped with oil circuit board) to connect the oil inlet interface at both ends of the cylinder, and the solenoid valve can be realized by power off (refer to the solenoid valve 2B2L, different solenoid valve actions are different).
