The invention belongs to reinforced ultra-high molecular weight polyethylene winding pipe and its preparation method. One or more layers of ultra-high molecular weight polyethylene profiles are used as winding materials, arranged in regular, mirror image or phase dislocation, and melted between adjacent side walls / periphery Interconnected or adjacent side walls / peripherals are fusion-bonded with frit material applied, and spirally wound to form the pipe wall; the wound material is stretched to orient the molecules along the longitudinal direction of the profile; reinforcement is applied to the UHMWPE base material materials and / or wear-resistant materials and / or flame-retardant materials and / or antistatic materials; welding materials are plastic polymers, or are reinforced and / or wear-resistant and / or flame-retardant and / or antistatic materials are applied to form plastic Melted co-extrusion; the distribution of reinforcing materials in the winding material and / or welding material is oriented in the helical direction along the axis of the high-strength winding pipe. It has higher impact resistance, yield strength, wear resistance, flame retardancy and antistatic ability, and can produce large-diameter pipes with small equipment.

The invention discloses a marine vertical deep well liquid cargo pump which comprises a motor component, a bearing component, a mechanical seal, an exit section, a support pipe, a middle support frame, a shaft, a shaft connecting component, a multistage flow guide housing, an impeller, an inducer, a suction section and the like, wherein a gaseous cold insulation cavity and a buffer cavity are sequentially arranged between the mechanical seal and the exit section from the top down to form two mechanical seal protection barriers; a multipoint sliding bearing support is arranged between a pump rotor and a casing; a middle limiting component is arranged in the middle of the pump; a bottom end limiting component is arranged at the undermost end of the pump; deviation of the whole pump due to swaying is avoided; the support pipe capable of sliding up and down is arranged at a shaft connecting part of a lower shaft; the shaft connecting component is dismounted by using a vacated space; and further, a whole lower shaft component can be taken out for maintenance. According to the pump, the service life of the seal can be prolonged, the swaying of the pump is avoided, the pump is convenient to dismount, as well as operates stably and is safe and reliable and long in service life under the working condition of length being 20m and working temperature being subzero 165 DEG C when liquid is pumped, and the pump is applicable to conveying LNG (Liquefied Natural Gas), LEG (Liquid Ethylene Gas) and LPG (Liquefied Petroleum Gas).

The invention discloses a carrier roller which can prevent materials from jumping in the conveying process. The carrier roller comprises a base. An installation plate is vertically arranged on the base. A through hole for the materials to pass is formed in the installation plate. A lower carrier roller for bearing the materials and an upper carrier roller for limiting jumping of the materials are arranged on the installation plate and the arrangement position of the upper carrier roller can be adjusted relative to the lower carrier roller.

Global modular fast-installation shelter and special-shaped aluminum profiles, butt aluminum profiles and construction methods, the adjacent panels of the shelter are connected by butt-joint aluminum profiles; butt-joint aluminum profiles include two snap-fit ​​joints of profiled aluminum profiles and buckle covers; The cross-section of the aluminum profile is L-shaped, and the connecting plates of the two special-shaped aluminum profiles are combined and connected by bolts, and the concave and convex parts form a tongue-and-groove connection; Cooperate with the blocking plate to realize the sealing of the connection seam. The invention adopts the method of making modules in the factory and splicing and assembling on site, which has low cost, less land occupation, convenient installation, short construction time, high strength, structural strength and rigidity all meet the requirements, and strong seismic performance; Simple and reliable; the overall keel frame is easy to bear heavy equipment boxes; filled with polyurethane foam, it has good air tightness and high structural strength; there is no special requirement for on-site construction conditions, green and environmentally friendly, and cost-effective.

The invention relates to an electric compressor (7) comprising: a compression mechanism (3); an electric motor (2) for driving the compression mechanism (3), said electric motor having an axis of rotation (X); and an electric motor (2) power supply inverter (1). The inverter (1) is mounted in an inverter housing (10), while the electric motor (2) is mounted in a housing (20) extending longitudinally along the axis of rotation (X) and having a first end (20P) connected to the inverter housing (10) by a plurality of securing devices (5). According to the invention, the motor (2) comprises a stator (2A) of circular periphery. Moreover, the internal periphery of the motor housing (20) is provided with a plurality of protuberances (23) that are in contact with the circular periphery of the stator (2A), and the internal periphery of the motor housing (20) is provided with a plurality of openings (29), between two consecutive protuberances (23), with at least one securing device (5) extending through said openings.

A non-adhesive composite pipe for delivering hot fluid or gas is composed of a metallic pipe, and two surficial layers which are the polyvinyl chloride layer with directional thermal shrinking memory function. Its advantages are high strength, light weight, and long service.
