Agricultural pump installation precautions and troubleshooting

Agricultural pump installation of technical requirements are very strict. First, the pump base should be strong, and try to shorten the length of the suction pipe. Second, the inlet pipe should be sealed and reliable. Bottom valve and hose fasten with insurance rope. Water sources for the channel, the bottom valve should be higher than the bottom of 0.5 meters, and screening to prevent debris into the pump. The third is in the pump belt drive, the tight edge of the belt should be in order to improve transmission efficiency. Pump impeller steering should be consistent with the direction of the arrow.

Check the pump should pay attention to three points:

(1) The pump shaft should be able to rotate flexibly without impact sound; the pump shaft should not be obviously swayed in the radial direction and need to add enough lubricant.

(2) Check whether there is damage to the inlet hose, crack if timely repair sticking. Check the fastening bolts are loose, to tighten loose bolts.

(3) submersible pump motor windings, cable insulation to meet the requirements in order to use.

Troubleshooting method:

(1) no water or no water, mostly due to the end of the valve stuck, part of the blockage of the water filter; absorbent height is too high or suction pipe leaks; and impeller flow blockage caused by, respectively, to take appropriate measures to solve.

(2) pipeline leakage or leakage, the bolt may not be tightened during installation. If the leakage is not serious, in the place of leakage or leakage of cement slurry, and tighten the nut with a wrench; if serious water leakage, we must reload.

(3) pump vibration, the rotor may be unbalanced, or poor coupling, bearing wear and bending; may also be caused by rotating parts loose, rupture and pipe support is not strong and so on. Should be adjusted according to different situations, reinforcement, straightening or replacement.

CNC Milling

CNC Milling Machine is an automatic processing equipment developed on the basis of general milling machine.The processing techniques of the two are basically the same, and the structure is somewhat similar.CNC milling machines are divided into two categories: without a tool magazine and with a tool magazine.The CNC milling machine with a tool magazine is also called a machining center.
Features
In addition to the characteristics of ordinary milling machines, CNC milling has the following features:
1.The parts are highly adaptable and flexible, and can process parts with particularly complicated contour shapes or difficult to control dimensions, such as mold parts and shell parts;
2.It can process parts that cannot be processed or difficult to machine with ordinary machine tools, such as complex curve parts and three-dimensional space surface parts described by mathematical models;
3.Parts that can be processed in multiple processes after being able to process a single clamping position;
4.The processing precision is high, the processing quality is stable and reliable, the pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, the numerical control processing also avoids the operator`s operation error;
5.High degree of production automation, can reduce the labor intensity of the operator. Conducive to the automation of production management;
6.High production efficiency. CNC milling machines generally do not need special process equipment such as special fixtures. When replacing workpieces, it is only necessary to call the machining program, clamping tool and tool data stored in the numerical control device, thus greatly shortening the production. cycle.
Secondly, the CNC milling machine has the functions of milling machine, boring machine and Drilling Machine, which makes the process highly concentrated and greatly improves the production efficiency.
In addition, the spindle speed and feed speed of the CNC milling machine are infinitely variable, so it is beneficial to choose the best cutting amount.
