Electric Sightseeing Vehicle Battery Charging Method:

1. The battery of the electric sightseeing bus must be guaranteed to be full on the same day after it is used. The battery of the electric sightseeing bus is charged after 10-15km in general, if the battery is left unused for a long time. It is still necessary to charge regularly.

2. The battery of an electric sightseeing car cannot always perform deep discharge, but it can be deeply discharged occasionally. If after a relatively long distance driving until the undervoltage indicator flashes out of power, then we are filling the battery. This is a good understanding of the battery's current capacity level.

3, electric sightseeing car can not be stored loss, loss of electricity storage is very easy to affect the battery life, if the battery is not used for a long time, the battery will also appear damaged.

4. The battery of the electric sightseeing bus must be regularly checked for safety within a certain period of time. The new electric sightseeing bus should check the battery after it has traveled continuously for 50km. When it is more than ten kilometers, it can be used. The multimeter is used to check the voltage value of the battery external terminal. Generally, it should be between 39-42 volts after the full charge is downloaded. If it is less than this normal value, or the other battery in the opened battery box, The voltage is less than 10.5 volts, then it may be a short circuit in its internal single cell, this situation should be timely to the maintenance station for repair or replacement, so as not to damage the other two together Normal battery. In addition, everyone should still check whether the charger has malfunctioned.

5. If the design weight of the electric sightseeing car is within 500Kg, then it is necessary to avoid loading too heavy materials, and it is also necessary to avoid frequent uphill as well as starting. Because the current loss of the motor at this time is relatively large, the battery will be discharged too quickly and the voltage will drop rapidly. The smaller the depth of discharge of the electric sightseeing car battery after each use, the longer the service life of the capacitor. Therefore, a good reduction in the discharge of large currents can extend the battery life of electric sightseeing vehicles , and it can also increase certain mileage. In addition, regardless of the battery capacity of the battery pack, everyone needs to develop a good habit of using with charging. (Text / Sun Ni)

Water Injection Pump

Water injection pump is the indispensable pump for high and stable out-put during middle and final stages of petroleum production. We can produce water injection pump independently, such as CYZSB standard pressure injection pumps and ZYZSB supercharging pumps have won national patent which number is ZL94247239.X.

Working Conditions:

        •Transport medium for water, oil, or oil and water mixture.

        •Solid content (proportion by weight) no more than 0.05%

        •The medium temperature is not higher than 80℃, and the environmental temperature is ±40℃.

        •The supply voltage should be 380V + 5% at 50Hz, special arrangement should be made if the customers have special requirements on frequency converter or click itself.

        •Inlet pressure and outlet pressure: The inlet pressure of standard injection pump is 0-2MPa (sufficient liquid supply should be guaranteed), the inlet pressure of supercharging should be 2-25MPa.

Water injection pump is mainly consisted of five parts:

1. Control Cabinet   2. diving motor   3. gaskets and shaft device  4. pump  5, base
