CB-B-type gear pump rotation problems and exclusion

CB-B-type gear pump rotation causes and exclusion ① axial clearance or radial clearance is too small. Re-adjust and repair. ② pump dirt. Disintegrate to remove foreign matter. ③ assembly error. Gear pump two pin hole machining reference plane is not assembly datum, such as the first pin into, and then tighten the screw, the pump will not move. The correct way is to turn the gear pump while tightening the screws, and finally with the pin hole and into the pin. ④ pump and engine coupling coaxial poor. Coaxiality should be guaranteed within 0.1mm. ⑤ Pump parts are not demagnetized. All parts must be demagnetized before assembly. ⑥ needle sleeve failed quality or needle broken. Repair or replace. ⑦ work oil outlet is blocked. Remove foreign body.

Ammonia Sensor

Ammonia nitrogen is a common pollutant in industrial, agricultural and domestic wastewater. Ammonia nitrogen will consume the dissolved oxygen in the water body, leading to eutrophication of the water body. The digital ammonia sensor measures ammonium ions based on the ion-selective method and consists of a working electrode, a reference electrode, an ion-selective membrane and an electrolyte. The ammonia nitrate probe is an online device for monitoring the content of ammonia nitrogen (NH4+-N) in water, which is suitable for various water bodies, including lakes, streams, groundwater and wastewater. The waterproof level of the NH4-N ammonia sensor is IP68, supports Modbus communication protocol, has automatic temperature and pH compensation function, and is environmentally friendly. The ammonia nitrogen probe has higher precision, wider measurement range and strong stability.

In sewage measurement, potassium ions and ammonium ions have similar chemical properties and are the most significant interference factor, which will cause high measured values. Therefore, potassium ion compensation is required. In addition, the temperature and pH of water samples are also dynamically compensated.
