-771x1000.jpg "NV-200 pumps")
The industries:
- public utilities,
- Special automotive industry,
- Oil industry,
- Chemical industry,
- Industrial and civil construction.
Purpose:
- The NV-200 pump is designed to create a vacuum (excess pressure) in
- tanks of Assenization (vacuum) machines for pumping
- sewer pits, collection of oil puddles, loading and unloading of cement to
- cement trucks, etc.,
- Recommended volume of the tank or tank 3.5 m3.
- The principle of action:
- The pump drive is carried out from the car change box
- Through a power selection box, a cardan shaft and a cuneiform transmission,
- In terms of design, the pump is a single-stage plate-rut. Pumping process
- based on mechanical absorption and pushing of gas due to
- periodic change in the volume of the working chamber formed by the cylinder and
- moving parts of the pump - a rotor, eccentrically installed in
- cylindrical housing and shoulder blades located in the grooves of the rotor.
