Diesel motor pumps are special units that are used to automatically pump various liquids and transport them over long distances. The devices are used in various fields - in agriculture, in public utilities, during extinguishing fires or in the elimination of accidents in which large volumes of liquid are released.

Motor pumps, regardless of the manufacturing plant, are divided into several types by technical characteristics and design features. For each type of work, certain types and models of units are provided.

Features and working principle

The main working structure of all motor pumps is the same - it is a centrifugal pump and a diesel internal combustion engine. The principle of operation of the unit is that special blades are fixed on the shaft rotating from the engine, located at a certain angle - opposite to the movement of the shaft. Due to this arrangement of the blades, when rotating, they capture the liquid substance and feed it through the suction pipe into the transfer hose. The liquid is then transported along the transfer or ejection hose in the desired direction.

The intake of liquid and its supply to the blades is carried out thanks to a special diaphragm. During the rotation of the diesel engine, the diaphragm begins to contract and creates a certain pressure in the structure - it produces a vacuum.

Due to the resulting internal high pressure, suction and further pumping of liquid substances is ensured . Despite their small size and simple design, diesel motor pumps have high power, long-term trouble-free operation and good performance. Therefore, they are very popular in various fields, the main thing is to choose the right device.

Varieties

There are several types of diesel motor pumps, which are classified according to their intended purpose. Each type has distinctive characteristics and technical capabilities, they must be taken into account when choosing products. Since if the unit is used for other purposes, it will not only be unable to ensure the proper quality of work, but will also quickly fail. Device types.

  1. Diesel motor pumps for clean water . They work on the basis of two-stroke internal combustion engines. They have low power and productivity, on average they are designed to pump out liquid with a volume of 6 to 8 m3 per hour. They are capable of passing particles with a diameter of no more than 5 mm contained in a liquid. They are small in size and emit a minimum noise level during operation. Perfect for agriculture or private use when watering vegetable gardens, garden plots.
  2. Diesel motor pumps for medium pollution water are also called high-pressure pumps . They are used by fire services, in agriculture for irrigation of large fields and in other areas of activity where water supply is required over long distances. Equipped with four-stroke engines capable of pumping out up to 60 cubic meters per hour. Head power - 30-60m. The permissible size of foreign particles contained in the liquid is up to 15 mm in diameter.
  3. Diesel motor pumps for heavily contaminated water, viscous substances . Such motor pumps are used not only for pumping out especially dirty water, but also for thicker substances, for example, sewage from a burst sewer. They can also be used for various liquids with a high content of debris: sand, gravel, crushed stone. The size of foreign particles can be up to 25-30 mm in diameter. The design of the mechanism provides for the presence of special filter elements and free access to the places of their installation, quick cleaning and replacement. Therefore, even if some particles are larger than the permissible values, they can be removed without allowing the unit to break down. The productivity of the devices allows pumping out liquid with a volume of up to 130 cubic meters per hour, but at the same time, a correspondingly higher consumption of diesel fuel occurs.

Modern manufacturers also produce special diesel motor pumps designed for pumping oil products, fuels and lubricants, liquid fuel and other flammable substances.

Their fundamental difference from other types of similar devices is in special structural elements of the overflow mechanism . Membranes, diaphragms, passages, nozzles, blades are made of special materials that have increased resistance to corrosion from harmful acids contained in liquids. They have high productivity, capable of distilling thick and viscous substances, liquids with especially coarse and solid inclusions.
