What it is?

A motor pump is a surface-type transportable pump, which is widely used in all areas of human activity. The most important technical parameters are performance for 1 minute, lift height, suction depth, hole size, motor power. This device consists of two parts that constantly interact with each other:

  • surface self-priming pump;
  • mechanical internal combustion engine.

The surface apparatus belongs to the type of dynamic vane devices . The hydraulic machine and the crankshaft of the engine with impeller blades are reliably connected to each other or manufactured in one piece. The liquid is set in motion by the impeller blades. Some models have multiple wheel stages. The movement of the wheels creates centrifugal force and different levels of pressure inside and out of the device.

To form the suction area, the designers placed curved blades on the moving disk, which are directed in the opposite direction relative to the movement of the wheel. The pressure difference inside the device and at the outlet facilitates the movement of the liquid, which moves from the inlet to the center of the installation and is poured out through the outlet. To increase productivity, experts recommend installing a motor pump at the level of water intake, which will significantly reduce its resistance.

Advantages and disadvantages

A motor pump is a simple device that is designed to pump water. Among the main advantages of the device are the following:

  • mobility;
  • versatility;
  • autonomy;
  • practicality;
  • low cost of components;
  • compact size;
  • ease of use;
  • minimum level of care;
  • long period of operation.

There are several types of pumps, which differ in the level of purification of the pumped liquid

  • For dirty water. They are used for pumping water with sand and gravel, the diameter of which does not exceed 30 mm. Scope - construction and emergency response.
  • For lightly contaminated water. They are used to work with water in which there are solid and fibrous particles no more than 0.1 cm in size. Scope of application - removal of water from flooded basements and drained reservoirs, for the performance of work by utilities.
  • For clean water. They have special filters with small cells. Scope - filling of pools and irrigation of agricultural crops.
  • For chemicals and liquid fertilizers.

Special attention should be paid to slurry, floating and diaphragm motor pumps, the design of which has a number of features. Slurry devices have a unique pump design, which makes it possible to move water with a large amount of silt, sand and gravel. The designers have provided for the possibility of quick disassembly of the device for cleaning the drive.

In floating diaphragm trailed motor pumps, the minimum capacity is 600 liters per minute. The main task of the device is to eliminate accidents and solve complex problems in hard-to-reach places. The period of operation at maximum load is 1 hour. The diaphragm device is used to transport viscous liquids and has a special principle of operation, which consists in lowering and increasing pressure due to the movement of the diaphragm and the blocking valve.

Motor pumps have been used for many decades in various areas of human life. Among the most significant are the following:

  • agricultural irrigation;
  • extinguishing fires;
  • water supply for private houses;
  • erosion of the soil surface;
  • moving large volumes of water between containers;
  • drainage pumping;
  • autonomous water supply in emergency situations;
  • pumping water from the emergency water supply system;
  • construction work;
Image

  • elimination of emergency situations;
  • elimination of accidents on the railway;
  • filling of pools and reservoirs;
  • drainage of wetlands;
  • pumping of oil products;
  • movement of chemical fluids and faeces;
  • cleaning of cesspools.
