Shanxi explosion-proof pump need to follow the conditions
Shanxi explosion-proof pump for conveying water and other liquids with physical and chemical properties similar to clear water. It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden irrigation, fire pressurization and equipment matching. It has the characteristics of simple structure, convenient maintenance and safe operation, and the conditions for the use of the machine are also very high. So, the next step is to give you a detailed introduction of Shanxi explosion-proof pump to follow the conditions:
1. The temperature of the conveying medium shall not exceed 100 ℃;
2. The explosion-proof pump can only be used if the rated value within the voltage range is ± 10%.
3, solid content (by mass) is not more than 0.01;
4. It is required that the well is upright, the well wall is smooth, and the well pipes shall not be staggered;
5, in order to prevent the explosion-proof pump suddenly start, the switch should be "off" (I. e. press in) before the power is turned on.
6. The water inlet of the water pump shall be below 1m of the dynamic water level, but the diving depth shall not exceed 70m of the static water level, and the water depth at the lower end of the electric pump shall be at least 1m from the bottom of the well.
7. The PH value of the pumped liquid is 6.5-8.5;
8. Do not abuse the power cord, and do not arbitrarily extend or exchange the power cord. It is not allowed to pull the power cord to scratch, cut or crush.
9. Three-phase AC power supply with power frequency of 50Hz and rated voltage of 300v or 660v (tolerance 5%);
10. Use the hand correctly. There is no plug at one end of the explosion-proof pump power cord. The user chooses the appropriate plug by himself. There are two sides and three points. Special attention:
1) If plugs and sockets are used in explosive and flammable places, they must comply with explosion-proof regulations. If they are installed in normal places far away from explosive and flammable places, 220V5A three-pin plugs can be used, of which one long leg of the explosion-proof pump is the grounding pin.
2) No matter what kind of plug is used, it should be reliably grounded. The yellow and green core wire at one end of the power cord is the grounding wire. When the connection is proper, it should also be checked whether there is electrical communication between the metal shell of the pump and the contact pin. The resistance should not be greater than 1 ohm.
11, prohibited places: in special environments such as wet, snow and corrosive gas places can not be used.
12. The pump of Shanxi explosion-proof pump is flameproof. Special attention should be paid to the flameproof surface of explosion-proof parts during brush replacement or maintenance. When repairing or replacing the brush, the motor should be opened to clean the carbon powder and oil rot in the inner cavity.
13, avoid the electrical level and water, oil in the installation of electrical level of the place, all the pump, do not damage the electrical level, and avoid oil, water and motor switches and other electrical parts of the contact.
is the use of Shanxi explosion-proof pump to follow several conditions, in order to ensure the safety of the use of the process, we must be familiar with the above content, so as to ensure the safety of the use of the process.
