QYW20-25pneumatic submersible sewage pump product instruction
QYW20-25 pneumatic submersible sewage pump system has the
advantages of simple structure, beautiful appearance, small volume
and light weight, and convenient maintenance Mobile; water
pumprunning smoothly, flow is large, the actual high lift; the
impeller and the pump body without clearance, drainage ability;
starting, stopping quickly, and have the function of overload
protection, not due to overload fault. Limit wind-driven
submersible pump without power,moisture, dust and other conditions,
especially for flammable and explosive, vibration, high
temperature...... The bad working condition of the safety and
reliability of the electric submersible pump can not be replaced.
In the work surface with firedamp and coal dust andother occasions
is absolutely safe and reliable.
QYW20-25pneumatic submersible sewage pump scope
QYW20-25 pneumatic submersible sewage pump is mainly used in the
mine development, mine shaft sinking, and chemical,
oil,shipbuilding and other inflammable and explosive bad working
site,construction drainage work compressed air as power.

QYW20-25pneumatic submersible sewage pump structure and working
QYW20-25 pneumatic submersible sewage pump by pneumatic motor,
water pump, oil mist, pipe and muffler is composed of five parts.
1.Pneumatic motor parts：
Consists of rotor, blade, cylinder, cylinder head, shell, bearing
cover,cover, etc.. A radial groove four uniformly distributed on
the rotor,groove equipped with blade, on the cylinder head, each
have a blowvent. The wind pump start-up, high pressure blowing from
the eye willslot leaves blown open, while a large number of high
pressure from the main air duct into the cylinder, the blades,
driven by the rotation of the rotor. In the bottom of the shell a
seal cavity, cavity sealing ring, water separated from gas. The
sealing ring adopts a spring sealing, and the use of gas, water
pressure, the seal ring up,enhance the sealing effect.
Which is composed of a pump body, impeller, pump seat. The impeller
is installed on the rotor shaft, tighten the nut mounted pump body,
impeller, pump base, into the water, the rotor drives theimpeller
to rotate, under the action of centrifugal force, vortex streetflow
pressure in the pump body, and then discharged from the water
3.Oil mist device part：
The oil mist, oil mist device shell, oil regulating valve core, oil
mist device is arranged on the top cover, filled with lubricating
4.Pipe joint part：
Consisting of two parts air inlet joint and a water outlet
elbow.Air inletjoint arranged on the air inlet.
Muffler is composed of steel plate stamping welded
together,installed in the exhaust port.
