Conditions of use of diesel engine self-priming pump set
The use conditions of diesel engine self-priming pump sets are crucial for their normal operation and efficient operation. The following is a detailed description of the use conditions of diesel engine self-priming pump sets:
1. Ambient temperature
The ambient temperature should be controlled within the range of ≤50℃ to ensure the normal operation of the diesel engine and the stable operation of the pump set.
2. Medium temperature
The medium temperature should be ≤80℃, and can reach 200℃ under special requirements. Excessive medium temperature may damage the pump body or seals, so it must be strictly controlled.
3. Medium properties
Diesel engine self-priming pump sets can handle a variety of media, including clean water, sewage, etc. However, different media have different requirements for pump bodies and seals. Before use, it is necessary to ensure that the pump set is compatible with the transported medium.
The pH value of the transported medium should be 6-9 for cast iron material and 2-13 for stainless steel material.
4. Medium specific gravity
The specific gravity of the pumped medium should not exceed 1240kg/m³ to ensure the normal operation and performance of the pump set.
5. Self-priming height and suction pipe length
The self-priming height of the ordinary diesel engine self-priming pump group cannot exceed 8 meters, and the suction pipe length is ≤20 meters.
The self-priming height of the vacuum-assisted diesel engine self-priming pump group cannot exceed 9 meters, but the horizontal distance can be extended according to demand, up to 300 meters.
6. Speed
The speed of the diesel engine self-priming pump group is generally 350r/min-1000r/min or 1500r/min. The specific speed should be determined according to the model and specifications of the pump group.
7. Other precautions
Before use, check the installation of all equipment to ensure that the pump group is firmly connected to each component and the seal is reliable.
Regularly check and maintain the pump group, replace worn parts, and ensure the long-term stable operation of the pump group.
Following the correct use conditions can ensure the normal operation and efficient operation of the diesel engine self-priming pump group.
