push plate cylinder are widely used in Tanzania，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed push plate cylinder for customers from Tanzania.

Introduction to push plate cylinder:

How to repair the push plate cylinder body when it is damaged: When the push plate cylinder has trace deformation and shallow tensile marks, the push plate cylinder is repaired by strong honing process. The heavy honing process can repair push plate cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the push plate cylinder can meet the technical requirements.

If it is found that the push plate cylinder lubrication is poor or the push plate cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the push plate cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the push plate cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the push plate cylinder center line. In this way, when the piston works in the push plate cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the push plate 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 push plate cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the push plate cylinder. The internal parts of the push plate cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the push plate cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the push plate cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the push plate cylinder bore processing is out of whack. Because the piston and push plate cylinder, guide rail and piston rod are relative If the push plate cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling push plate cylinder weight composition and calculation. The weight of the push plate cylinder is composed of the push plate cylinder diameter, the outer diameter and weight of the push plate cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

The daily inspection of the push plate cylinder includes: checking the connection of the push plate cylinder and the pipe joint for leaks. Check the push plate cylinder rod for leaks. Check the push plate cylinder connection for leaks. When the push plate cylinder moves, the work is normal and smooth. Whether the push plate cylinder has internal leakage.

Answers to some questions about push plate cylinder:

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.
