Embodiment Construction

[0030] Such as Figure 1 to Figure 6 As shown, a pneumatic opposite-acting plunger pump includes a pump body 7, the pump body 7 is a casting, the inner cavity of the pump body 7 and the contact surface of the plug 10 have a Cr plating layer of 0.08 mm to 0.12 mm, and the preferred The inner cavity of the pump body 7 and the contact surface of the plug 10 have a 0.1mm Cr plating layer. Cr-plated layer, the surface of this coating is smooth and flat, which reduces the frictional resistance between the sealing ring and the cavity; and this coating has a relatively strong anti-rust ability, because the medium water quality of the continuous casting workshop is complex and there are corrosion factors, so the existence of the Cr-plated layer can Greatly extend the service life of the pump.

[0031] The left and right sides of the inner cavity of the cylindrical pump body 7 are respectively provided with a group of plug bodies, and the upper and lower sides of the middle part of the...

Abstract

The invention discloses a pneumatic opposite acting plunger pump which comprises a pump body. The left side and the right side of an inner cavity of the barrel-shaped pump body are each provided with a set of plungers, and an upper water outlet and a lower water inlet are machined in the upper side and the lower side of the middle of the pump body respectively. A flange and a driving mechanism are mounted at the ends of the left side and the right side of the pump body respectively. The plungers on the left side and the right side of the pump body and the driving mechanism have the same structure; the left plungers comprise piston rods, belleville springs I, bolt plugs and belleville springs II, and the belleville springs I, the bolt plugs and the belleville springs II sequentially penetrate through the ends of the right sides of the piston rods. According to the pneumatic opposite acting plunger pump, by means of reasonable water pump cylinder design, the water suction and drainage capacity of a water pump is amplified, an opposite double-plug mode is adopted, the flowing property of water is reasonable, energy consumption loss is reduced, blocking is not likely to happen, and the failure probability is reduced.

Description

technical field [0001] The invention relates to an energy-saving water pump with a pneumatic opposing plunger. Background technique [0002] The working conditions of the water pumps in the continuous casting production workshop of the metallurgical industry are relatively harsh, and they are generally used for circulating cooling water for equipment such as crystallizers and sectors. There are also a large amount of cooling iron sheets, sediment and other large particles of impurities in the water, which are relatively turbid, and generally have a large flow rate. The pump works for a long time, consumes a lot of power, and has a high failure rate, which increases the production cost of the enterprise. [0003] At present, most of the water pumps for sedimentation tanks or production processes in continuous casting workshops use centrifugal water pumps or reciprocating plunger water pumps (driven by motors). The main problems are: [0004] 1. Centrifugal water pumps have l...
