The hydraulic system is an independent hydraulic device

The hydraulic system is a relatively complete project, which not only needs to consider whether the thrust (or torque) and speed reach the requirements, but also needs to meet the action requirements of mechanical equipment, and increasingly needs the miniaturization and long service life of the hydraulic system. The structural method of the hydraulic station is mainly distinguished by the structural method of the pump equipment, the location of the equipment and the cooling method. The solenoid of the reversing valve of the equipment above the hydraulic station is loose and the coil is short-circuited. This can directly replace the reversing valve and perhaps repair it. The hydraulic oil in the hydraulic station is contaminated and the spool is stuck. Replace all hydraulic oil with clean uncontaminated hydraulic oil. At the same time, the stuck valve can only be replaced by the reversing valve or repaired. In the hydraulic system, each pressed component has a relative movement of the surface, such as the inner surface of the hydraulic cylinder and the outer surface of the piston, due to the relative movement, so there is a certain gap between them. Assuming that one side of the gap is high-pressure oil and the other side is low-pressure oil, the high-pressure oil will flow to the low-pressure area through the gap and then form a leak. At the same time, due to the imperfect sealing of hydraulic components, part of the oil will leak to the outside. This leakage constitutes a reduction in the practice of traffic, which is what we call traffic loss.

Hydraulic cylinder manufacturers can easily complete the conversion of rotation and linear reciprocating motion of the working mechanism

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.

Hydraulic cylinder how to reduce noise?

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.

Low working pressure of hydraulic cylinder under no-load condition

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.

Hydraulic system reliability is very important

Sometimes the pressure of the hydraulic system will suddenly drop automatically, and then slowly return to the large value, which is the so-called pressure fluctuation. The main reason is that the oil is mixed with air when the oil is added or stirred, and the precipitated impurities are stirred up. Since various impurities such as iron filings, abrasives, dust and other dirt will enter the system before use during the processing and transportation of various components and pipelines of the hydraulic station, all valves, oil pipes and oil tanks should be fine cleaned before use of the hydraulic station, and the oil pipes should be cleaned by pickling. The selection and correct use of hydraulic oil, hydraulic oil filtration and other aspects of management, to improve the safety of the hoist braking system, reliability is very important, that is, the correct maintenance and maintenance of the hydraulic station.

What are the benefits of daily maintenance of hydraulic systems

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?
