Super-start water jet loom

Abstract

The invention provides a super-start water jet loom comprising a loom body (800) and a water treatment device; the loom body (800) and the water treatment device are all positioned on a set working site; the working site is provided with a waste water tank (700); the loom body (800) is arranged on the waste water tank (700) in a spanning manner; the water treatment device is distributed on one orboth sides, positioned along the width extension direction, of the waste water tank (700); the water treatment device includes a control box (400), a control panel (401) is arranged in the control box(400), and the control panel (401) includes a loom super-start control system. In the super-start water jet loom disclosed in the invention, space of a box body is reasonably distributed, an originally narrow walkway can be prevented from being occupied by too many parts on one side. Two phase over-modulation technologies are adopted in the loom super-start control system, a modulation ratio is increased, the amplitude value of fundamental wave voltage is compensated, IGBT switching frequency can be lowered, and switching loss can be reduced.

Description

technical field [0001] The invention relates to the field of looms in the textile and weaving industry, in particular to a super-starting water jet loom. Background technique [0002] The weft yarn of the water-jet loom is sent out by spraying water, and the water spray forms waste water after contacting the fabric, air, and the loom body, which contains impurities such as grease, suspended solids, and chemical slurry. The traditional water jet loom discharges the wastewater into the water system after being treated by chemical methods through the ditch and the treatment pool. For example, the patent document CN201458911U discloses a comprehensive sewage treatment system for water jet looms, which includes a sewage liquid storage tank, a lifting pump room, a grease trap, a multi-stage reaction tank, a biochemical tank, a secondary sedimentation tank, and a valveless filter tank connected in sequence. The multi-stage reaction tank is also connected with a physical and chemic...

AI Technical Summary

Problems solved by technology

The shortcomings of traditional water jet looms are: waste water cannot be recycled, resulting in waste of water resources, and there are problems such as lack of supervision in the sewage treatment process

When the existing three-phase asynchronous motor is just started, the slip rate s=1, the rotor leakage reactance is the largest, the power factor of the rotor side is very low (about 0.3), and the active component of the rotor winding current is very small when starting, resulting in high starting current and low rotation speed. little moment
