Problems solved by technology

Before the invention of this tool, it was very difficult to cut the tubes to analyze the cause of leakage. Firstly, the shell plate of the evaporator should be cut into multiple sections, and only one section can be taken from the outer tube bundle. Such tube analysis is not representative. And it will cause a lot of environmental pollution, and waste manpower and material resources, high cost and low efficiency

Abstract

The invention relates to a tube cutter, which comprises cutting element, transmitter, guide blade rod and feeding steel wire, wherein the cutting element is at the head of guide blade rod; the transmitter is at the end; the cutting element is mounted on the square hole at the head of blade rod; the return spring blade is inserted into the hole of blade via screw to be fixed at the guide blade rod; the transmitter via adjusting sheath is fixed on the guide blade rod; the rotation sheath is on the blade rod; the rotation handle is connected to the rotation sheath via screw; the feeding nut is connected to the tail of guide blade rod via screw; one end of feeding steel wire is connected to the feeding taper via screw; via rotating the feeding nut, the steel wire will move taper downwards to expand the cutting. The invention can reduce pollution, reduce cost and improve efficiency.

Description

technical field [0001] The invention relates to a cutting device, in particular to a pipe cutting device in a narrow space. Background technique [0002] There are many kinds of pipelines and heat exchangers on marine products. The water quality control is not strict during operation, which will cause various corrosions. After a long time, leakage will occur. After leakage, the water quality of the circuit will be polluted, the dosage will exceed the standard, and the equipment will be damaged. . When replacing the tube, it is necessary to design and develop a cutting device that meets the requirements of use. Before the invention of this tool, it was very difficult to cut the tubes to analyze the cause of leakage. Firstly, the shell plate of the evaporator should be cut into multiple sections, and only one section can be taken from the outer tube bundle. Such tube analysis is not representative. And can cause very big environmental pollution, and wasted manpower, material...
