(Dominica steering power cylinder,produced by Hengyu Hydraulic Cylinder Factory）

steering power cylinder are widely used in Dominica，because of long service life，smooth movement，high work efficiency.So our company has designed steering power cylinder for customers from Dominica.

Introduction to steering power cylinder:

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

If the steering power cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the steering power cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow steering power cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the steering power cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the steering power cylinder includes the leakage caused by excessive wear of the steering power cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and steering power cylinder, and the phenomenon of "pulling the steering power cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

When producing oil steering power cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

If it is found that the steering power cylinder lubrication is poor or the steering power cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the steering power cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the steering power cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the steering power cylinder center line. In this way, when the piston works in the steering power cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the steering power cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Answers to some questions about steering power cylinder:

What is the bearing capacity of the HOB cylinder?
The normal specification of HOB is 140 kg pressure, which is more commonly used in the market, and there are clear marks on the cylinder, 210 kg is a strengthened version of HOB, generally customized cylinders are also clearly marked on the above, when the specific use of the cylinder, the maximum use pressure is marked on the cylinder.

What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.
