Description

PE pipe installation method suitable for reel sprinkler

Technical Field

The invention relates to an installation method for a reel sprinkler, in particular to an installation method for a PE pipe, which is suitable for installing the PE pipe on the reel sprinkler and belongs to the technical field of reel sprinklers.

Background

The spray irrigation is an irrigation method that water is sprayed into the air by using special equipment such as a spray nozzle and the like to form water drops which fall on the ground spray irrigation surface and the surface of crops.

The reel sprinkling irrigation machine can irrigate farmland of large area, also can be according to the size of shower nozzle control water spray volume to satisfy the user and to the different requirements of sprinkling irrigation water yield, be the sprinkling irrigation equipment that farmland water-saving irrigation chooseed for use usually. Reel sprinkling irrigation machine generally adopts water turbine formula power drive system, mainly include chassis, reel, PE pipe, water turbine, gearbox, speed compensation device and shower nozzle car usually, the winding is overlapped on the reel in the PE pipe, and the pressure water of sprinkling irrigation drives water turbine rotatory, spreads into the reduction gear from the water turbine axle in, and chain drive produces great moment of torsion power drive reel rotation after the deceleration to realize the automatic of PE pipe and retrieve, pull the shower nozzle car through the PE pipe simultaneously and roll back the removal and carry out the sprinkling irrigation operation.

The PE pipe one end of reel sprinkling irrigation machine need cup joint and install on the hard pipe connector of pressure water input of shower nozzle car, the other end needs to cup joint and install on the hard pipe connector of pressure water output of reel, the hard pipe connector usually is the bamboo joint coupling structure with PE pipe internal diameter size tight fit, traditional PE pipe box joint mounting means is that the manual work that manpower was used for strength to push into the PE pipe after smearing the butter on the hard pipe connector cup joints the mode, cup joint PE pipe back reuse larynx hoop tighten the PE pipe tip on the bamboo joint coupling structure of hard pipe connector. The PE pipe of the coil sprinkler is used as a pressure water delivery working part, and not only has enough supporting strength in the radial direction to resist extrusion deformation and pressure of pressure water when being wound on a coil, but also has enough tensile strength in the axial direction to pull a sprinkler car. For large-and-medium-sized reel sprinkling irrigation machine, the nominal pressure of PE pipe is usually at 0.63 ~ 1.6MPa, the external diameter is usually at 65 ~ 250mm, the pipe wall thickness is usually at 4.2 ~ 22.7mm, weight is great, when adopting the traditional manual mounting means that cup joints the PE pipe, usually heat earlier the tip of PE pipe and soften the later manpower cup joint, the heating means adopts flame heating or hot oil heating usually, not only intensity of labour is big, the installation cycle is long, the installation effectiveness is low, and the outer surface of PE pipe tip can be damaged usually to the mode of flame heating or hot oil heating, and then cause the PE pipe tip to have the risk of premature aging, thereby can reduce reel sprinkling irrigation machine product overall quality.
