We have 5 different irrigation systems to meet more irrigation requirements:
Center pivots, Towable pivots, Laterals ( Linears ), Hose reels, PE pipe sprinklers.
A.Center pivot irrigation system moves like the pointer of a watch, all wheeled towers move around the center point in a circular pattern. Crops in the corner can not be irrigated or less irrigated by an end gun. It’s the most important irrigation method.
B.Towable pivot irrigation system have a skid or 3 or 4 wheels assembled at the center point. After one plot of land finished irrigating, farmers can use a tractor to tow the irrigation system to another land.
C.Lateral ( Linear ) irrigation system is the best choice for rectangle lands. It moves along one side or in the middle of the land and gets water from ditch or hose. The diesel generator and pump are always mounted on the cart.
D.Hose reel irrigation system is suitable for a small farm less than 6 hectares. The water is sprayed by a big gun at the end of PE pipe.
E.PE pipe sprinkler irrigation system consist of PE pipe, PE joints and sprinklers. This kind of irrigation system is installed on the ground and water will be pushed through pipes and sprayed by a lot of sprinklers. It’s also a good choice for a small farm.

There are many factors that affect the price of irrigation systems. Which irrigation system is your choice? Center pivots, laterals, towable pivots ? What sprinklers and end gun are suitable for the crops ? Nelson D3000, R3000, S3000 ? Senninger Iwob ? Nelson SR75, SR100 or Komet series end gun ? Do you need auto stop and reverse function ? Different lengths of irrigation systems need different water flow and the diameter of main pipes. It leads to price differences. Zhonghui provides 10” (254mm), 8”(203mm), 6-5/8”(168mm) and 5-9/16”(141mm) four different sizes to suit different needs.

A.20 feet container × 40 feet GP container √ 40 feet open top container √ B.Zhonghui irrigation systems’ main pipe is 22’ ( 6.70 meters ) long, for whole irrigation system can only use 40 feet container. And Center pivot, towable pivot, lateral are heavy cargos, the weight is key factor to calculate the containers for whole irrigation system. Based on our experience, one 40 feet GP container can load about 600 meters irrigation systems. If you use 40 feet open top container, it will be easier to use cranes to unload the cargos when it arrives at your farm. C.For parts, we will calculate base on the actual situation.

As we all know, different farms have very different topography, if you don’t make an irrigation system design, you cannot choose a suitable irrigation system. It’s a very important step to do. To design a great irrigation system, it takes a lot of knowledge about irrigation as well as all of the involved equipment including pipes and pumps. Our designers specialize in center pivot, lateral move systems, pipes and pumps. 
13.Do you provide installation service ?

A.If there is Zhonghui authorized dealer in your country or region, they will send engineer to your farm guide installation and training.
B.If there is no Zhonghui dealer in your country or region, according to the quantity you purchased, we will send 1, 2, or 3 engineers to your farm.
C.All engineers are well trained to qualify the job.
D.You should bear the round tickets, accommodation charges and pay USD80/engineer/day.
14.What I need to watch during installation ?

A.Erect the machine in a straight line. This will make the initial alignment easier.
B.Check for the correct half pipe location and truss rod length used in the span.
C.Rod lengths are shown on the span drawings.
D.Caution must be used to prevent the spans from tipping or rotating when raised and attached to the pivot or previous tower.
E.Don’t forget to put the flange gaskets between the pipe sections. Use caution in aligning the flanges to one another to insure that the gasket is not dislocated.
F.During assembly of the pivot, apply an even coat of grease to the pivot elbow. Before the machine is operated, grease the fittings against using one tube. Wipe off any excess grease that may be forced out above the pivot head pipe under the top shield to avoid grease entering the collector ring.
G.Do not use any solvent-based lubricants or cleaner on or near collector rings, control panels or other electrical fixtures using polypropylene or polycarbonate covers, bases or other components. Contact with solvent-based materials can have an adverse effect on these plastics increasing the chances of material cracking, breaking and causing decals to come loose.

To maximize the drive train life of your center pivots, laterals and other irrigation equipment, periodically drain any water that accumulates in the gearbox and center drive, and make sure the gear lubricant is at the proper level.

Be sure to fill deep wheel tracks during the off-season to reduce stress on irrigation, tillage, and harvest equipment. To help prevent future tracking, consider changing to a higher floatation tire, adding a floatation drive unit option, or modifying the sprinkler package to reduce water application to the wheel tracks.

Water application is at the heart of what you do, in order to do this as best possible; sprinkler packages need to be properly designed and maintained to a high degree of accuracy. Generally, sprinkler packages should be replaced at least every 10,000 hours of operation. Regularly check for broken or worn sprinkler components and replace them as necessary. Also, consider running a new sprinkler design that could maximize uniformity and application efficiency, and help alleviate application issues such as runoff, ponding and soil sealing.
20.Tire Pressure

Maintaining the correct tire pressure is vital to the operation of center pivots, laterals and other irrigation equipment; the correct tire pressure ensures that flotation for a particular tire is maximized and the rolling circumference is consistent to what Valley uses on timer chart calculations. Be sure to periodically check tire pressure and adjust it to specification. Also, don’t forget to tighten wheel lug nuts and evaluate the overall tire condition. All tires lose pressure over time and lose or gain about 1 PSI per 10 degrees F of temperature change.  
21.Pivot Alignment & Pipe Flushing

Ensure the tower box micro-switches are set properly. Improper settings can cause pivot misalignment, which results in nuisance shutdowns. Flushing your pipe line and cleaning your sand trap is essential if you have water quality problems or your irrigation water contains sand.

Be sure to power down the equipment before checking any electrical connections. Once the power is off, check for loose connections or loose cord grips in tower boxes.
