Vertical type highly effective energy-saving abrasion-proof pump

Abstract

The invention discloses a vertical high-efficiency energy-saving wear-resistant pump. It solves the problems of long self-priming time, low efficiency, large vibration and large noise of the current vertical self-priming pump, and has the advantages of high efficiency and energy saving, quick start, small vibration, low noise, wear resistance, corrosion resistance, and no The fault running time is long, the wearing parts are easy to replace, the pump shaft is shortened, the pump runs smoothly for a long time, the sealing ring is externally sealed with cooling water, and there is no leakage at all. The mechanism is as follows: it includes an upper pump body, the upper end of which is connected with the motor mounted on the motor bracket, the lower end of the upper pump body is connected with the lower pump body through the volute, the side of the upper pump body is the discharge pipe, and the lower pump body and the water inlet pipe connection, the pump shaft is connected with the motor through a rigid coupling, the lower part of the pump shaft is provided with an impeller device, the pump shaft penetrates into the upper pump body, a sealing device is arranged on it, and a vacuum exhaust pipe is arranged on the sealing device; The pump body is provided with a vacuum detection probe, and the vacuum exhaust pipe and the vacuum detection probe are connected with an external vacuum exhaust device.

Description

technical field [0001] The invention relates to a vertical pump and a vacuum exhaust device, in particular to a vertical high-efficiency, energy-saving and wear-resistant pump. Background technique [0002] Vertical self-priming pumps currently used in metallurgy, electric power, mining, environmental protection, chemical industry, light industry, pharmaceuticals, papermaking and other industries have long self-priming time, low efficiency, long pump shaft cantilever, and large vibration and noise during operation, which is not conducive to Energy saving and environmental protection, can not meet the demand for quick start of water pumps. The water pump volute is not easy to repair and replace. Contents of the invention [0003] The purpose of the present invention is to solve the problems of long self-priming time, low efficiency, large vibration, and loud noise of the current vertical self-priming pump, and provide a high-efficiency energy-saving, fast start, small vibr...
