The steering wheel of the loader is too heavy？

[BONOVO]

The steering hydraulic oil temperature is too low, should wait for the loaderhydraulic oil temperature rise before starting to work. If the oil supply to the steering pump is insufficient, the loader oil pump should be checked for wear or damage, and the oil pump assembly should be replaced in serious cases.

Air enters the steering oil circuit, causing the steering cylinder to move when not moving, the air should be removed from the system, and check whether the steering pump suction pipe is loose and leaking.

If the steering system pressure of the loaderis low, the pressure of the valve should be adjusted according to the regulations, or the relief valve should be cleaned and the spring or seal should be replaced.

In addition, the loadermanufacturer reminds you that because the steering pressure of the loaderwith full hydraulic steering is too low, it should be repaired according to its different models.

For the fully hydraulic steering gear, it may be that the bolts of the steering gear metering motor are too tight, and the bolts should be relaxed, or it may be that the steel ball check valve in the steering gear fails, and the dirt should be cleaned out so that the steel ball and the valve body seal belt are in good contact.

loaderaccessories mainly produce various specifications of hydraulic gear box, torque converter and torque converter accessories and other accessories. During the intake process, the crankshaft rotates and the piston moves from the top to the bottom stop point, when the intake valve has been opened.

When the piston is lowered, the volume above the piston increases, creating a vacuum suction, and fuel and air are atomized through the carburetor into a combustible mixture that is drawn into the cylinder through the intake valve.

After the piston reaches the bottom stop, the intake valve closes and the intake stroke ends.

During the working stroke, when the piston approaches the top dead point, the spark plug generates an electric spark between the electrodes.

The compressed combustible mixture ignites and the combustion gas expands rapidly.

The instantaneous pressure in the loadercylinder reaches 2940kPa-4410kPa, the temperature reaches 1800-2000C, and under the action of high pressure gas, the piston "moves from the top dead point."

Through the connecting rod, the thrust of the high-pressure gas is transferred to the crankshaft, so that the crankshaft rotates and works, and the heat energy is converted into mechanical energy.

Exhaust stroke: At the end of the working stroke, when the loaderpiston is pushed close to the bottom dead point, the exhaust valve opens, the piston moves from the bottom dead point to the top dead point, and the exhaust gas after combustion in the cylinder is pushed by the piston and discharged through the cylinder.

Exhaust valve, when the piston reaches the upper dead point, the exhaust valve is closed and the stroke is over.
