Connect the positive pole of the battery to the positive pole of the power supply and the negative pole of the battery to the negative pole
The initial charging is carried out in two stages: first, the initial charging current is charged to the electrolyte to release bubbles, and the cell voltage rises to 2.3 to 2.4V. Then, the current is reduced to 1/2 initial charging current, and the charging is continued to the electrolyte to release a vigorous bubble, which is stable for 3 consecutive hours. The total charging time is about 45~65h.
During the charging process, the temperature of the electrolyte should be measured by halving the current, stopping charging or cooling. The temperature is controlled at 35~40 °C. When the initial charging is completed, if the specific gravity of the electrolyte is not specified, distilled water or electrolysis with a specific gravity of 1.4 is applied. The liquid is adjusted. After adjustment, recharge for 2 hours until the specific gravity meets the requirements.
The new battery often fails to reach capacity after the first charge, and a discharge cycle should be performed. Discharge at a discharge rate of 20hh, and then replenish the charge current. If the capacity is still less than 90% of the rated capacity after one charge and discharge cycle, a charge and discharge cycle should be performed.
Polypropylene is a thermoplastic belonging to the polyolefin group. Wuxi Yuda Plastic Welding Machinery provides welding equipment to handle all diameter sizes offered and has an extensive line of fusion machines available to buy for every application. Polypropylene pipe can be bent in the field, also polypropylene fabrication of plastics can be made like HDPE in workshops.
Polypropylene (PP) Pipe and Fittings assembly and joining of this system is performed by heat fusion. Fusion joints are made by heating and melting the pipe and fitting together. This type of joint gives a homogeneous transition between the two components without the lowering of chemical resistance associated with solvent cement joining and without the loss of integrity and loss of pressure handling ability of a threaded joint.
Five different fusion methods for Polypropylene Piping Systems are available and commonly used in today`s demanding applications. These include conventional socket fusion, electrofusion, conventional contact butt fusion.
For Polypropylene Pipe Fabrication, it can use Yuda Workshop Fitting Welding Machines and Plastic Pipe Saw. Polypropylene (PP) is a partly crystalline thermoplastic similar to HDPE. Both of them have same welding process but in different welding temperature. For more information for PP Fusion Welders, feel free to contact Wuxi Yuda Plastic Pipe Welding Machinery Factory
