High pressure low density polyethylene pipe is divided into low-pressure polyethylene pipes and two kinds of high-density polyethylene pipe. Low high-density polyethylene pipe for the hard pipe, thin wall. Pressure polyethylene pipes for the semi-hose, thick wall, the terrain adaptability is stronger than the low-pressure high-density polyethylene. High-pressure polyethylene pipe pressure low density polyethylene resin by adding stabilizers, lubricants and a certain proportion of carbon black made of the same diameter connector - Shandong Laiwu YURUN Irrigation Equipment Co., Ltd. is a PE / PVC plastic pipe, pipe fittings, sprinkler irrigation, micro jet, drip irrigation, micro-irrigation, springs irrigation, filtration, fertilizer and other water-saving irrigation equipment developing small irrigation machine is mainly used to irrigate farmland mountain hills and plains for a variety of crops and soil, in water-saving irrigation equipment occupies an important position. Small irrigation machine before use to do a series of preparations, we should pay attention when using a lot of issues. And real-time care and maintenance in order to give full play to the role of light and small irrigation. 1. The use of personnel must be familiar with the composition of sprinkler units, nozzle structure, performance, and successive checks various components including pumps, piping, nozzles, etc., and observe the parts are complete, technical condition is normal. If found damaged or missing parts should be repaired or configuration, in order to keep the system has good technical condition. 2 operating position shall be firm soil, or into the ground to prevent collapse. 3 Install the inlet pipe should be taken to prevent water leakage, the filter to be completely submerged in water, the depth of about 30cm, and with the bottom of the pool wall to maintain a certain distance in order to prevent inhalation of sediment and other impurities and air. 4 Before starting the pump, fill the water pump should be filled with water and the pump inlet, before starting; pump water storage should be above the impeller axis, in order to ensure the normal process of self-absorption.
