Working principle of the central swivel joint of an excavator

Working principle of the central swivel joint of an excavator

The central swivel joint of excavators is mainly used in the entire hydraulic system of large-tonnage tower cranes and other machinery. Including a rotating body and a rotating shaft, the small end of the rotating shaft is self rotating, the rear end is axially inserted into the rotating body, and the small end of the rotating shaft is equipped with a baffle. Fixed, rotating body, fixed with end cover at the rear end, the rotating shaft, with the large end extending out of the rotating body, the rear end outward, and the rotating shaft.

What is the reason for the vibration of the multi way valve during operation

What is the reason for the vibration of the multi way valve during operation

1. The pipeline support of the multi way valve is unstable, and the common cause of vibration is the looseness of the water pump base and foundation bolts. In this case, we only need to tighten the bolts.

Precautions for testing multi way directional valves

Precautions for testing multi way directional valves

The multi way valve is mainly a widely used equipment in different industries and fields such as engineering machinery, mining, metallurgy, etc. It is mainly a load sensitive proportional directional multi way valve with pressure compensation. When designing and manufacturing the multi way valve, people mainly use an integrated modular design method to design and manufacture it, which can provide a very reliable system solution for engineering vehicle manufacturers, So, what precautions should people pay attention to when using multiple directional valves and conducting experiments on them?

Specific product characteristics of multi way directional valves

Specific product characteristics of multi way directional valves

An important device used in many mechanical equipment is a multi way valve. Multi way valves are mainly used to control fluid, which not only facilitates fluid control and makes mechanical equipment easy to operate and control, but also a type of valve that can change the on-off relationship of different oil channels connected to the valve body through continuous movement between the valve core and valve body, Generally, this type of multi way directional valve is a combination valve mainly composed of two or more directional valves. So, what are the specific product characteristics of multi way directional valves?
