Mobile diesel pumping station

When you hear aboutmobile diesel pumping stations, you immediately imagine something like a generator on wheels - but no. The main mistake beginners make is that they confuse mobility with versatility. The station must not just travel, but remain operational in field conditions, when there is neither a stable power supply nor a workshop around the corner.

Structural subtleties that you won’t see in catalogs

Let's take the frame. It would seem that there is nothing complicated here - I welded the frame and it was done. But if you do not provide points for slinging, the pipes will be damaged when loading by crane. Udiesel pumping stationsfrom Shandong Linyao Intelligent Agriculture Technology LLC this is taken into account - the frame has reinforced eyes, offset from the center of gravity.

Wheels are a different story. Wide tires are suitable for sandy soils, but they are useless on clay after rain. At one of the facilities in the Astrakhan region, we had to urgently replace wheels with tracked modules. Now I always advise customers to analyze the type of soil before the start of the season.

Vibration is an invisible enemy. Without damping gaskets between the frame and the pump unit, the pipe connections begin to leak after 200-250 operating hours. Tested at stations with gear pumps - where ordinary metal on metal was used, cracks appeared in the welds after the first month.

Diesel engine: choosing between power and endurance

People often chase horsepower and forget about torque. Formobile pumping stationStability of operation at low speeds is more important - for example, when you need to maintain pressure in a drip irrigation system without sudden jumps.

Chinese Weichai engines perform well in temperate climates, but for the Far North it is better to take Cummins or at least YaMZ. The difference in price pays for itself in one season - less downtime due to frozen fuel filters.

The cooling system is the nuance where mistakes are most often made. Air cooling is simpler, but when working in dusty conditions (cleaning the territory of elevators, for example), the radiators clog within 4-5 hours. Closed-loop water cooling is more reliable, but requires more qualified maintenance.

Fuel nuances that are not written in the instructions

Summer diesel fuel at -15°C turns into a gel, even if you add anti-gel. Tested at station DNS-50 - we had to urgently install fuel line heating. Now I always check with clients what season the equipment will be used.

Real cases from the practice of Shandong Lingyao LLC

Last year we assembled a station for vineyards in Crimea. The customer required the possibility of alternating operation from a diesel engine and from the tractor PTO. We made a hybrid scheme - we had to redesign the frame to accommodate two independent drives. But now this modification has become standard for agricultural enterprises.

There was also a failure - when watering a quarry in the Rostov region, they did not take into account the abrasiveness of the suspension. The gear pump failed after 72 hours of operation. We had to urgently deliver a screw pump with reinforced rotors - now we always check the degree of water contamination.

An interesting experience with remote control - initially they used radio modules, but in hilly areas the signal was constantly interrupted. We switched to GSM control with duplication of commands via SMS. This solution is now used in projectssmart agriculturefor remote control of irrigation.

Compatible with fertigation systems

Most stations do not take into account the chemical aggressiveness of fertilizers. Pumps from Shandong Linyao LLC use stainless alloys for impellers - this increases the cost of the design by 15-20%, but increases the service life when working with ammonium nitrate by 3 times.

Dosing is a separate headache. Smooth performance adjustment is not always necessary. Sometimes it is more profitable to use a bypass system with excess return to the tank - this way the control valves wear out less.

Filtration before and after the station is an often overlooked point. If you do not install a coarse filter on the suction, sand will damage the seals in 2-3 days. And without a fine filter, the drip lines become clogged at the outlet. I always recommend a two-stage system, even if the water looks clean.

Field tests in the Stavropol region

We tested a station with the ability to operate on different types of fuel. It turned out that when switching from diesel to biofuel, you need to change the maintenance intervals - resins are formed 1.5 times faster. We added an additional separator to the design - the problem disappeared.

Prospects for the development of mobile pumping solutions

Now we are experimenting with hybrid installations - diesel + solar panels. For daytime watering in southern regions, this provides fuel savings of up to 40%. But the problem with sudden engine starts has not yet been solved - when the panels are shaded, the power drops abruptly.

Automation of diagnostics is the next step. In new stations we are testing the built-in vibration analysis system. If the permissible values ​​are exceeded, the station automatically reduces the speed and sends a notification to the operator. This is especially important formobile diesel pumping stationsworking offline.

Materials - we are gradually switching to composite casings. They are lighter than metal ones and do not rust, but are still more expensive. But the weight of the structure is reduced, which is important for frequent movements across fields.

Unobvious aspects of operation

Transportation seems like a small thing, but it is during transportation that 30% of damage occurs. We have developed instructions with strict requirements for fastening - especially for stations with centrifugal pumps that are sensitive to shock.

Seasonal storage - if the cooling system is not drained, the radiator tubes will burst if it freezes. And the remaining fuel in the tank forms a sediment over six months, which will clog the injectors. We definitely carry out conservation work for stations that have been idle for more than 3 months.

Noise control - often overlooked, but when working near residential areas, conflicts arise. We install additional casings made of noise-absorbing materials, although this increases the dimensions.

Overall,diesel pumping station- not just a device, but a comprehensive solution. There are no universal options; each project requires adaptation. The main thing is not to skimp on consultations with engineers before purchasing, so as not to redo it later. As the practice of Shandong Linyao Intelligent Agriculture Technology LLC shows, the correct selection of parameters at the design stage eliminates 80% of problems in operation.
