(Australia sanitation truck hydraulic cylinder,produced by Hengyu Group）
sanitation truck hydraulic cylinder are widely used in Australia，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed sanitation truck hydraulic cylinder for customers from Australia.
The method of sleeve sanitation truck hydraulic 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 sanitation truck hydraulic cylinder can be significantly improved by rolling in the finishing of the inner holes of the sanitation truck hydraulic cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.
The sanitation truck hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure sanitation truck hydraulic cylinder can use 20 steel pipe, and the high pressure sanitation truck hydraulic cylinder can use 45 steel pipe.
Repair method of small range wear of oil sanitation truck hydraulic cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.
sanitation truck hydraulic cylinder use should try to avoid sealing belt into the sanitation truck hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the sanitation truck hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the sanitation truck hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
Why is the hydraulic cylinder of the larger excavator arm upside down?
The weight of the excavating arm of a large excavator will be very heavy, and an oil cylinder has two cavities, one is a rod cavity, and the other is a rodless cavity. The lifting force of the excavator is the product of the ortho-projection area of the piston rod cavity by the oil pressure, so the strength of the rodless cavity is much greater than that of the rod cavity. And the parallel bars with the piston rod facing down are also conducive to assembly and future maintenance. So a large excavator has to keep the cylinder facing down.
What is the smallest cylinder size?
The smallest shape cylinder I have ever seen is a hydraulic clamping cylinder in the machine tool industry. Outer diameter 24 mm, total length 23 mm, travel 4 mm. Weighs 0.05 kg. Maximum clamping force 3500 Newtons.
