Split double suction pump
1. Replace the sealing ring After long-term use in sewage media, the gap between the impeller and the sealing ring may increase and need to be replaced in a timely manner. 2. Place in a ventilated and dry place When not in use, the water pump should be promptly lifted away from the water source and the accumulated water inside the pump should be drained, especially in cold winter. 3. Regularly ins...
(1) Wedge type single gate valve ① The structure is simpler than that of an elastic gate valve; ② At higher temperatures, the sealing performance is not as good as elastic gate valves or double gate valves; ③ Suitable for high-temperature media prone to coking. (2) Elastic gate valve It is a special form of wedge type single gate. Compared with wedge gate valves, they have good sealing performance...
A hydraulic pump is the power component of a hydraulic system, which is driven by an engine or electric motor to suck in oil from the hydraulic oil tank, form pressure oil, and discharge it to the actuator. 1. Gear pump: smaller in size, simpler in structure, less strict in oil cleanliness requirements, and cheaper in price; But the pump shaft is subjected to unbalanced force, severe wear, and sig...
Centrifugal pump is one of the most commonly used pumps in water transportation. The elevation of the floor in the pump room depends on the installation height of the water pump. Correctly calculating the maximum allowable installation height of the water pump is of great significance to ensure safe water supply and save civil construction costs. In order to avoid the occurrence of cavitation, the...
The fifth China Valve City Longwan International Valve Exhibition, which lasted for three days, was successfully concluded at the Wenzhou Olympic Convention and Exhibition Center on the afternoon of May 29th. More than 400 companies showcased their costumes at this exhibition, attracting 103 national merchants from Fujian, Tianjin, Shanghai, Jiangsu, Henan, Hebei, Beijing, Guangzhou, and internati...
Many people prioritize stainless steel pumps when pumping seawater or saturated salt water. They feel that the stainless steel material is durable and does not require much maintenance, but it is faster to detect damage when used, and the stainless steel pump is severely corroded. Seawater is a very complex multi-component aqueous solution. The main elements in seawater include Na ions, K ions, CL...
In the process of using pneumatic valves, it is usually necessary to configure some auxiliary components to improve the performance of pneumatic valves or improve the efficiency of their use. Common accessories for pneumatic valves include air filters, directional solenoid valves, limit switches, electrical positioners, etc. The assembly of three air source processing components, namely air filter...
During the use of pumps, it is inevitable to encounter some small "symptoms". Do you know how to "treat" these "symptoms" when they arrive? Today we will talk about some common "symptoms" and "treatment" methods of water pumps. 1. The water pump cannot start Firstly, the power supply situation should be checked: whether the connectors are securely connected; Whether the switch contact is meticulou...
Before purchasing a water pump, many users believe that choosing a higher head water pump for a lower head operating condition has a wider range of head usage. In this misleading misconception, when purchasing a water pump, the pump head chosen is very high. In fact, for centrifugal pumps, when the pump model is determined, its power consumption is directly proportional to the actual pump and flow...
