Solar Water Pump with AC DC Controller

Warranty: 3 Years for the motor and controller. Solar panel comes with a 20-year warranty (optional). Installation Instructions: 1. Wiring the Pump Connect a longer cable to the pump. The cable size must be at least 1.5mm². Use the parts from the cable connector kit (heat-shrink tube and tape) to connect a longer supply wire to the pump. If you don't have a heat gun, the barrel of your soldering iron can work, or you can use a butane torch carefully so that you don’t melt the insulation or cause a fire. Make sure to strip the insulation back as shown in the diagram. A. Lay out all the components needed for the connection. B. Place the large diameter heat-shrink over the main cable, then the smaller diameter pieces over the individual wires. Keep the heat-shrink away from the joints while soldering. Any heat transfer may cause premature shrinking. C. Slide the small heat-shrink over the soldered joints and apply heat using a heat gun or alternative heat source to shrink the sleeve tightly around the wires. D. Wrap the tape over the sealed joints for extra protection. E. Finally, slide the large diameter heat-shrink over the completed joint and shrink it to ensure a secure and waterproof connection. Before starting to wire the controller box, place the pump in water. This allows the pump to go through its pre-conditioning process. Do not install the pump in its final position until it has been tested, unless it is easy to access and remove. Solar Pump Control Box Features: A. Low-voltage protection (automatic) B. Over-current protection (automatic) C. Protection for low water level in the well (AB sensor) D. Protection for full water level in the tank (LH sensor) E. Motor speed control (speed regulator) F. Delayed operation when the tank is full (a timer inside delays operation for 30 seconds when the tank is not full) G. MPPT function (Maximum Power Point Tracking) H. Battery optional (can be used with a solar charger battery system) Please refer to the attached images for visual guidance on installation and product details.

Spline & Gear Shafts

DAYUE manufactures splines and gear shafts to your drawing specifications

DAYUE manufactures a range of splined and gear shafts for various industries.

Typical uses are heavy duty steering gear for commercial and earth moving vehicles.

It is also widely used in commercial winches, transmission fields, new energy, semiconductors, dynamic brakes, classic vehicles and many other industries that require forward drive systems.

Splines are ridges on the teeth cut on the drive shaft that engage with grooves in the mating piece and transmit torque to it, keeping the angles between them corresponding and can be used in many mechanical transmissions. Helical and Spur Gears can also be cut on the shaft to provide dual drives as required by certain industries.

DAYUE can manufacture splines on shafts that are routinely cut on gear cutters, or we can manufacture shafts and splines in a single unit on our 5-axis Integrex machines, ensuring full concentricity between shaft and splines.

Parallel keys and involute splines as well as serrations can be manufactured according to customer's drawings.
