(Puerto Rico filling machine cylinder,produced by Hengyu Hydraulic Co., Ltd）

filling machine cylinder are widely used in Puerto Rico，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed filling machine cylinder for customers from Puerto Rico.

Introduction to filling machine cylinder:

The filling machine cylinder is not the same as the filling machine cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the filling machine cylinder can not be used as a high-power power component, but the filling machine cylinder can be used as a relatively large power component, or the filling machine cylinder system can be used.

The method of sleeve filling machine cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the filling machine cylinder can be significantly improved by rolling in the finishing of the inner holes of the filling machine cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

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

If the filling machine 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 filling machine cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow filling machine cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the filling machine cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the filling machine cylinder includes the leakage caused by excessive wear of the filling machine 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 filling machine cylinder, and the phenomenon of "pulling the filling machine cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

Answers to some questions about filling machine cylinder:

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.

What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.
