2.2-5.5kw Inner Shaft Electric Gear Motor Clockwise Rotation For
Cleaning Machine Machine
Hollow Shaft Motor
Hollow Shaft Electric Motor Description
The hollow shaft motor is an open metal pipe, and an impeller is installed on the inner
wall of the hollow metal pipe. The impeller is fixed to the bearing
of the inner wall of the pipe shaft by welding or other methods.
No precision requirement means that the hollow shaft of the motor
or the dimensional accuracy of the inner hole is not high. The
inner hole is mainly used for routing, light transmission, or other
media such as air.
The design of the hollow shaft motor greatly optimizes the
mechanical design, facilitates wiring, and saves design space and
production costs.
Advantage:
1. high-quality materials, 100% output power, slight current, low
temperature, the heat dissipation is good, energy-saving. 2. high-quality bearings, rigorous assembly process, and low noise. 3. Tailored for professional cleaning equipment, the shaft
extension is subjected to high-frequency quenching treatment, which
significantly improves the mechanical strength and seamlessly
connects with the cleaning equipment to realize worry-free
operation.
Hollow Shaft Electric Motor Application
Hollow shaft motors have a wide range of uses and can be used as
pumps, high-pressure washers, misting machines, car washes, etc.

What are the reasons and treatment methods for the insufficient
pressure of water pressure of the high-pressure cleaner:
1. The high-pressure nozzle of the high-pressure cleaning machine
is severely worn. Excessive wear of the high-pressure nozzle will
affect the water pressure of the equipment. Therefore, the new
nozzle should be replaced in time.
2. The Insufficient inlet water flow of the connected equipment
leads to insufficient water flow, resulting in inadequate output
pressure. Therefore, supply enough water flow in time to solve the
problem of lower water pressure.
3. The high-pressure washer cleans the water inlet filter with air.
After exhausting the air in the water inlet filter, ensure that the
standard outlet pressure is output.
4. After the aging of the overflow valve of the high-pressure
cleaner, the overflow of the water flow is large, and the pressure
becomes low. Therefore, it is necessary to replace the parts in
time when it is aging.
5. The high and low-pressure water seal of the high-pressure washer
and the check valve of the inlet and outlet water have caused the
leakage of the working pressure, which should be replaced in time.
6. High-pressure pipes and filter devices are kinked, bent, or
damaged, resulting in poor water flow and insufficient pressure,
and should be repaired in time.
7. The internal of the high-pressure pump is faulty, the wearing
parts are worn, and the water flow is reduced; the internal
pipeline of the equipment is blocked, and the water flow is too
small, resulting in too low working pressure.
