Sludge suction reflux pump

Sludge suction reflux pump

QWHCharacteristics of the series submersible reflux pump: Submersible reflux pump with micro head, high flow rate, and high efficiency The impeller has a hydraulic design structure, and the swept back blades have self-cleaning function, anti clogging, and anti windingTwo mechanical seals, made of tungsten carbide - tungsten carbide, with bearings and all fasteners made of stainless steel, can ensure continuous operation of the pump10000More than hours. Compact structure, simple operation and maintenance, easy installation and maintenance, long service life. The host adopts a cast or stainless steel pressure forming structure, with small volume, high density, corrosion resistance, and no noise The insulation level of the motor winding isFGrade, protection level isIP68Factory products are equipped with protection and alarm devices for leakage, water leakage, and motor overload to ensure the reliability and reliability of the products

It is a new product developed based on the production technology of submersible mixers. This pump is used for mixed liquid flow and denitrification in secondary sewage plants, and can also be used for pumping purified water during ground drainage; Irrigation and control of waterway systems; Micro head and high flow areas are required in the recycling or mud suction circuits during the waste process.

1、 Product Introduction:QWHtypeSubmersible reflux pumpThis is a new product developed in the production technology of submersible mixers. The pump is used for the reflux of mixed liquid in secondary sewage plants and for denitrification Denitrification can also be used for pumping purified water during surface drainage, irrigation, and controlling waterway systems, as well as for recycling or mud pumping during waste processes Micro head and high flow areas are required in the circuit.

2、 Product Usage: Submersible reflux pumps are mainly used in industries such as municipal engineering and environmental protection engineering, and can be used to discharge sewage with solid particles and fibers, reflux sludge, and wastewater. The submersible reflux pump is independently developed based on the production technology of submersible motors The product, submersible reflux pump, is used for mixed liquid reflux and denitrification denitrification in secondary sewage treatment plants It can also be used for ground drainage, irrigation, and waste disposal Recirculation and other processes that require micro head and high flow rate Place.

3、 Structure Introduction: Submersible reflux pump three-phase squirrel cage motor,380Vthree-phase50HZProtection levelIP68Stator insulation levelFLevel, start directly.

Submersible reflux pump bearings - using lifetime lubricated bearingsExceeding the service life40000Hour.

Submersible reflux pump impeller - The axial running three bladed impeller of the reflux pump is equipped with technology, and the impeller has good self-cleaning and vibration free functions. The design of the impeller can be full at the same time The requirements for high flow rate and low head are met, and a large flow rate is formed in the axial direction.

Submersible reflux pump sealing - using motor sealing technology to ensure reliable sealing.

Submersible reflux pump sealing monitoring - When water enters the oil chamber, the humidity sensor in the probe side leakage system will automatically issue an alarm signal to detect it in a timely manner and prevent the occurrence of problems Secondary malfunction.

Temperature monitoring - The motor winding adopts an 11 degree overheat protection process. Once the motor is overloaded, the medium temperature is too high, or other reasons occur When overheating occurs, the temperature sensor will promptly issue an alarm signal or automatically shut down the water pump before the temperature exceeds the allowable temperature limit.

Automatic coupling system - The reflux pump is equipped with a single rail automatic coupling system to ensure quick installation, lifting, and maintenance.

5、 Product Description: Power consumption:1.5-22KWImpeller diameter:400-640mmInsulation level of submersible reflux pump:FSubmersible reflux pump material: cast all stainless steel/Ordinary cast iron (can be customized according to customer requirements)

6、 Usage conditions: 1: Altitude not exceeding2000m1. High ambient temperature50Celsius degrees, mediumPHvalue in3--12Between them, the liquid density does not exceed1150kg/m3. Long term diving operation, with a diving depth generally not exceeding20m； 2During operation, the pump must not be lower than 1 low liquid level. 3The rated voltage is380V,The rated frequency is50HZThe deviation between rated voltage and rated frequency shall not exceed plus or minus5%Only then can the motor operate normally.

7、 Installation system diagram:QWHThe series submersible reflux pump adopts a guide rail automatic coupling installation system: the guide rail is fixed on the pool wall, and the shore lifting device and through wall outlet pipe are installed and fixed. The sludge reflux pump can slide freely up and down along the guide rail, making installation and maintenance extremely convenient.QWHThe series of sludge reflux pumps require pre embedding of the through wall outlet pipe, and the guide rail and lifting device are connected to the tank body with expansion bolts, without the need for pre embedded parts.
