The working principle of the excavator hydraulic swivel joint:

When the excavator is working, its chassis and the upper operating body need to perform relative slewing motion. How to realize this movement that requires 360° rotation requires the core component of the excavator hydraulic swivel joint. When the excavator rotates, the hydraulic oil is delivered to the travel motor through the excavator hydraulic swivel joint, the hydraulic oil is connected from the main control valve to the internal cylinder, and the travel motor oil circuit is connected to the casing structure.

The inner cylinder is cast with annular grooves (ie oil passages) from top to bottom, and the outer casing is also cast with small grooves corresponding to the grooves (used to install the rotary joint sealing ring). When the machine rotates, the casing is fixed, and there is relative movement between the inner cylinder and the casing (the cylinder rotates in the casing). Because the oil passage is circular, the machine can be turned arbitrarily within the circumference range, and the casing oil passage can be kept connected with the corresponding mandrel oil passage to realize continuous rotation.

The central slewing joint for excavators consists of two parts: the inner cylinder and the outer shell, the shell is provided with a flange, which is fixed to the center of the slewing bearing, the shell is connected to the upper pipe, and the mandrel is connected to the lower pipe road.

Kyushan is established in 2004 , we produce OEM mini excavator swing bearing replacement, slew drive, pinion, FH has passed ISO9001-2005, SGS, CAPE etc, FH also accept the service durability test, resist fatigue test, anti-corrosion test and anti-terrible temperature test, which is widely used for Construction machinery, port, AI and new energy industries.

What should I do if the excavator seal leaks oil?
More than 90% of the oil leakage problems are because the rubber excavator seal has been subjected to alternating cold and warm temperatures for a long time, resulting in the loss of a large amount of plasticizers and softeners in the sealing ring, and the problem of corrosion, aging and hardening occurs.

The phenomenon of oil dripping started slowly, and the sealing ring broke after a long time. In the past, the oil leakage was solved by dismantling the engine and replacing the oil seal. Now with the development of technology, the leakage can also be solved by not disassembling and repairing. oil problem.

Daily use and maintenance of turbocharger for excavator accessories

The status of the turbocharger excavator can actually be controlled through daily maintenance and careful use. In the final analysis, as long as the following maintenance work is done in place, the turbocharger will be fine!

After the excavator is started, you cannot directly turn the accelerator knob as soon as you start the car. It should run at idle speed for 3-5 minutes. This is to increase the temperature of the oil and improve the flow performance, so that the turbocharger can be fully lubricated. Increase the engine speed for normal operation.

Excavators are most prone to high water temperature failures. Today, I shared with you the high water temperature failure caused by theexcavator water pump.

How to check if the excavator water pump is working? Remove the thermostat, turn it on, run at idle speed and high speed repeatedly, press the water pipe to see if there is water passing through the water pipe, if the water pipe is hard, it means the pressure is normal, then open the water tank cover and observe whether the water flow speed is normal.

What should I do if the excavator water pump leaks? Open the top cover, disassemble the fan water blocking ring, check the inside of the water pump belt, open the bottom plate of the oil pan, and confirm the specific leakage location. If the oil seal of the water pump and the pad of the water pump are damaged, they can be replaced directly.

-- Excellent flexibility of excavator belt
-- High power transmission efficiency
-- Reduced noise of excavator belt
-- a power transmission belt featuring multiple longitudinal ribs.
-- It transmits the torque by contact of the belt rib flanks and the pulley grooves.
-- It has been designed with a larger contact surface area than V belts or flat belts.

Maintenance method of excavator radiator:
1. Avoid hot air recirculation during construction
The filler near the radiator is often called a "sponge". But it cannot replace any "sponge". The needs of the excavator are mainly to avoid the recirculation of hot air, so corrosion resistance, temperature resistance and air permeability must be insufficient.

That is, when the cold air drawn in from the front of the excavator radiator rises in temperature and enters the rear of the radiator (engine compartment), it cannot return to the front of the excavator radiator. When the hot gas returns to the radiator, the heat dissipation of the system is reduced, the temperature of the oil and water increases, the engine does not work properly, and may be damaged prematurely. Therefore, when operating a small hydraulic excavator below 30,000, it is impossible to ignore the observation and correction of the "sponge" near the radiator, and it is necessary to replace a part in time.
