We often say that prevention is in the bud, in fact, the daily maintenance of equipment is the same. How to do a good job in the daily maintenance of the hydraulic system? What are the benefits of the hydraulic system manufacturers?

Crane hydraulic cylinders are critical components in the heavy machinery and construction industries, enabling precise and powerful lifting, lowering...

The hydraulic cylinder is small in size and light in weight, so the inertial force is small. When suddenly overloaded or parked, no big impact will occur. It can automatically adjust the traction speed smoothly within a given range, and can complete the speed regulation. The commutation is simple, and the conversion between the rotation of the working mechanism and the linear reciprocating motion can be completed more conveniently without changing the rotation direction of the motor. The hydraulic pump and the hydraulic motor are connected by oil pipes, and they are not severely restricted by each other in spatial arrangement. Because the oil is selected as the working medium, the relative moving surfaces of the components can be lubricated by themselves, with small wear and long service life. Check the hydraulic system once every day. Including check the motor operation, hydraulic pump operation, each solenoid valve is sensitive, etc. If there is an anomaly, deal with it immediately. Otherwise, it shall not operate. Regarding the determination of the output speed of the electric equipment, when the valve has no strict requirements for its opening and closing time, the slower speed should be selected as far as possible.

The gap between the cylinder barrel and the piston in the hydraulic cylinder is mainly determined by the size of the cylinder and the seals used in the standard spacing. These two are used to choose. The use of the cylinder, in general, there are four main types, is the boom on the elastic cylinder and luffing cylinder, as well as the leg on the elastic cylinder and straight cylinder. Among them, the boom elastic oil cylinder is used to adjust the boom length, and the boom luffing oil cylinder is used to adjust the boom elevation angle.

The low working pressure of the hydraulic cylinder under no load condition is a comprehensive index reflecting the accuracy of the production and installation of hydraulic cylinder parts and the size of the sealing conflict force. Hydraulic cylinder at full load movement without crawling phenomenon of low speed, it does not have a unified index, bear the different work of the hydraulic cylinder, the low stability of the speed requirements are not the same. The wear ring on the piston is severely worn, causing conflicts between the piston and the cylinder liner, pulling the cylinder liner, piston and seal. Seal long-term use failure, piston seal (mostly U, V, Y ring, etc.) aging. The hydraulic oil is dirty, and a large amount of impurities enter the cylinder to wear the piston seal to a bad condition, usually iron filings or other foreign matter.
