Overview
The centrifugal pumps of our company, manufacture in strict accordance with the standard JB/T6663.1-93,which mainly consist of impeller,casing,sealing,bearing body etc, apply to convey clear water or others whose properties similar to water.
The medium temperature can’t exceed 176°F.
It has two type of drive, one is the power machine connect with the pump directly by a Coupling, another is the power machine and pump rotate through the pulley. The power machine can be the diesel engine or electric engine, the user can select as required.
Scope
Primarily supporting the use of light-small sprinkling machine, and fixed permanent or semi-permanent sprinkler system, widely applied to irrigation of various farmlands, orchards, vegetable farms and nursery garden, it can also use as self-priming pumping unit for water supply and drain of urban construction, factory and mine.
Use and maintenance
- you should make the pump working in the standard rotate speed in use process, don’t speed up at will, in order to avoid potential safety hazard and impact the useful life of the pump.
- Direct coupled type pump units,the chassis must remain stable, so as not to damage the coupling. Belt wheel type pump units,the two pulleys must be aligned, the belt loose or tighten must be moderate. If the pump doesn’t turn, it is generally because the impeller-ring get rusty, you can use the mallet knocking the coupling axially.
- Pump mounting height(in order to suction the water tank as the base)should be less than the permit smoking on 1-2meter high vacuum.
- You should stop the engine if you discover abnormalities(such as noise, shock, hydraulic discharge descend etc.),and attention the bearing heat up, the temperature can’t exceed 75°C.
- If stop using for a long time, you should discharge the water in the pump, overhaul and oil, keep it in a dry and ventilate shade. In winter, you should discharge the water at once when you stop using it in case frost crack.
- After the pump every 1000 hours operating time, you should take down and clean the bearing, and exchange quick-wear parts.
