Mobile pumping station

When you hear “mobile pumping station,” you immediately think of something like a trailer with a motor pump, but in reality it is a complex technological complex. Many customers still confuse mobility with primitiveness, and then wonder why Chinese analogues fall apart after two seasons of watering.

Design features that are not noticeable at first glance

Assembling the pumps on the chassis is 20% of the work. The main difficulty is to ensure stable operation under pressure drops and automatic flow control. Last year we tested the station for Shandong Linyao Intelligent Agriculture Technology LLC - there we had to completely redo the hydraulic accumulator mounting system, because standard solutions could not withstand vibration when transported on dirt roads.

People often forget aboutmobile pumping stationshould have not just overheating protection, but an intelligent diagnostic system. In our projects we use vibration sensors on bearings - it seems like a small thing, but they prevented at least three serious failures in the field.

Another nuance is the location of the shut-off valves. If you place the shafts and valves where it is “logical” according to the drawings, during emergency repairs in the mud and darkness the operator will spend an extra 15-20 minutes on access. This has been proven by bitter experience.

Real use cases in agriculture

In 2022 we launchedmobile pumping stationfor drip irrigation in the Stavropol Territory. The customer required pumping 50 m3/hour at a pressure of 80 meters, but they did not take into account that the water from the artesian well contains sand. We had to urgently modify the multi-stage filtration system - standard mesh filters became clogged after 4-5 hours of operation.

An interesting experience was with the project of an intelligent agricultural park, where the station had to be synchronized with a weather station. It turned out that with a sharp increase in air humidity, it is necessary not to reduce, but to increase the pressure in the line - due to a change in the viscosity of water. Such nuances are not specified in the instructions.

Now on the website https://www.lyzhihuinongye.ru you can see our latest developments in remote control. But frankly, in field conditions, duplicated manual control is more reliable - especially when the connection is lost at the most inopportune moment.

Typical mistakes when choosing equipment

The most common mistake is skimping on the soft start system. It seems that you can get by with ordinary starters, but when you have to frequently switch operating modes, the engine fails in 2-3 months. Tested at three sites in the Rostov region.

Customers also often underestimate the importance of unifying spare parts. If a station has pumps from three different manufacturers, then if it breaks down you have to wait weeks for spare parts. We at Shandong Linyao Intelligent Agriculture Technology Co.,Ltd always insist on a unified component platform.

Protection against vandalism is a separate story. It seems that no one will climb into the field, but in practice, the lack of grilles on the ventilation holes and anti-vandal locks leads to constant theft of copper busbars and sensors.

Features of seasonal operation

Winter storage is a separate headache. If you do not drain the water from all cavities, even in an insulated container the pipes will burst. In this case, you cannot use antifreeze - it is detrimental to the seals. We have developed a compressed air blowing system, but it also requires manual control.

Spring startup is always accompanied by problems with the stuffing box seals. After inactivity, they lose elasticity, and leaks are inevitable during the first 2-3 days. It is better to immediately schedule maintenance during this period.

In summer, the main problem is overheating of diesel generators. Standard cooling systems are not designed to operate at +40°C in the shade; additional fans must be installed. But they also need to be protected from straw and fluff.

Prospects for the development of mobile pumping systems

Now everyone is talking about 'smart agriculture', but in practice automation depends on the quality of communication. Satellite modems are too expensive, and cell phones work intermittently. It may be worth developing autonomous systems with local control logic.

An interesting direction is hybrid power plants. Solar panels could cover up to 40% of energy consumption, but their fragility does not yet allow use in mobile solutions. Although experiments at Shandong Linyao Intelligent Agriculture Technology Co.,Ltd show encouraging results.

The main trend is not an increase in power, but an increase in efficiency. Modernmobile pumping stationshould consume less fuel with the same efficiency. Our new energy recovery solution shows savings of up to 15% compared to five-year-old models.

Practical maintenance tips

We have developed a simple checklist for field mechanics: check the tightness of all threaded connections once a week (vibration weakens even lock nuts), monitor the temperature of the bearings with the back of your hand every shift (easier than it seems), and never skimp on gearbox oil.

When transporting, be sure to secure not only the main equipment, but also the control panels. Microcracks on printed circuit boards do not appear immediately, but after 200-300 km along dirt roads.

There should be a supply of filters for at least two full service cycles. During high season, delivery may be delayed, and running without filters is a sure way to ruin your pumps within a couple of days.
