Pump overview

  A water pump is a machine that delivers or pressurizes a liquid.

  Liquids, gas mixtures, and liquids containing suspended solids can also be delivered. The technical parameters of the pump performance include flow, suction stroke, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volume pump, vane pump and other types. The volumetric pump uses its change in the volume of the working chamber to transfer energy. The vane pump uses the interaction of the rotating blades and water to transfer energy. There are centrifugal pump, axial flow pump and mixed flow pump.

Water pump introduction

  A water supply pump is a type of water pump that is a machine that delivers or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid, mainly for transporting liquids including domestic water, waste water, and the like. It has the characteristics of high efficiency, energy saving, compact structure, overall disassembly and sealing, convenient maintenance, pipeline installation and small installation space.
  A water pump is equivalent to a water supply device. A water supply device that automatically starts and stops a certain flow rate and lift head per unit time.

According to the purpose: fire, life, production three categories:
   1. Fire water supply pump: Water supply equipment for fire protection purposes.
   2. Living water supply pump: Water supply equipment for daily use.
   3. Industrial water pump: Water supply equipment for production use.

Scope of application:
1. Residential water for high-rise buildings, residential quarters, villas, etc.
2. Daily water use in enterprises, institutions, hotels, office buildings, department stores, large saunas, hospitals, schools, gymnasiums, golf courses, airports, etc.
3. Production water for production, washing equipment, food industry, factories, industrial and mining.
4. Others: renovation of old pool water supply and other forms of water supply.

Introduction to centrifugal pumps

  A centrifugal pump is a pump that delivers liquid by centrifugal force generated when the impeller rotates.
  The centrifugal pump works by rotating the impeller to cause the water to undergo centrifugal motion. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and water to perform high-speed rotation movement, the water is centrifugally moved, and is raked to the outer edge of the impeller, and flows through the volute pump casing. The road flows into the pressurized water line of the pump.
  The basic structure of the centrifugal pump is composed of eight parts: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, sealing ring, stuffing box, axial force balance device.

Introduction to Submersible Sewage Pump

  The submersible sewage pump is a submersible sewage pump that can tear, cut and discharge the long fibers, bags, belts, grass, cloth and other materials in the sewage, and then discharge smoothly. It is especially suitable for conveying liquids containing hard solids and fibrous materials and special Dirty, sticky, slippery liquid.

  Use range: Discharge of heavily polluted wastewater from factories and businesses. Urban sewage treatment plant drainage system. Sewage discharge station in residential areas. Civil air defense system drainage station. Sewage discharge from hospitals and hotels. Municipal engineering, construction sites. Exploration and mine supporting machine. Rural biogas digesters, farmland irrigation

The main purpose:
1 Enterprise unit wastewater discharge.
2 urban sewage treatment plant discharge system.
3 subway, basement, civil air defense system 
drainage station.
4 sewage discharge from hospitals, hotels and
 high-rise buildings.
5 sewage drainage stations in residential areas.
6 Municipal engineering, discharge of mud in 
construction sites.
7 water supply device of the water plant.
8 farm sewage discharge and rural farmland irrigation.
9 Exploration mines and water treatment equipment.
10 instead of shoulders to pick people, sucking river
 mud. The condition water temperature is ≤60 ° C, and the
 liquid pH is 4-10.

  Constant pressure water supply is a water supply system for water conservancy systems. The ability to keep the water supply pressure constant keeps the water supply and water in balance, that is, the water supply is increased when the water is used for a long time, and the water supply is also less when the water is used less, thereby improving the quality of the water supply.
