(Croatia sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

sanitation truck hydraulic cylinder are widely used in Croatia，because of clever hydraulic energy conversion，no transmission clearance，powerful torque.So our company has designed sanitation truck hydraulic cylinder for customers from Croatia.

Introduction to sanitation truck hydraulic cylinder:

If the sanitation truck hydraulic cylinder slips or crawls, please check whether there is astringency inside the sanitation truck hydraulic cylinder, because the internal parts of the sanitation truck hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the sanitation truck hydraulic cylinder changes with the different stroke position, and the slip or crawl occurs. 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 sanitation truck hydraulic 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.

Before the sanitation truck hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

When the sanitation truck hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the sanitation truck hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the sanitation truck hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the sanitation truck hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair sanitation truck hydraulic cylinder are not high.

If the seal of the sanitation truck hydraulic cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

Answers to some questions about sanitation truck hydraulic cylinder:

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
