Problems solved by technology

[0003] At present, there is no feed pump specially used for transporting N2H4, NH3 and other hydrogenated nitrogen. Therefore, improving the traditional pump and making it develop towards hydrogenated nitrogen is beneficial to today's industrial production and has great significance for industrial production.

Abstract

The invention discloses a double-feeding type delivery pump. The double-feeding type delivery pump comprises a pump body. A worm, a turbine and two eccentric shafts are arranged inside the pump body in a rotating mode, wherein the turbine is in normal-running fit with the worm, and the two eccentric shafts are connected to the two ends of a turbine shaft of the turbine. One end of the worm is connected with a rotating shaft of a motor. Two pump cylinders are arranged on the outer side of the pump body. Each pump cylinder is internally provided with a piston bush, and pistons are arranged inside the corresponding piston bushes. One end of each piston is connected with a piston rod, and one end of each piston rod stretches into the pump body and is further provided with a spring retainer. The spring retainers and the corresponding eccentric shafts are periodically in normal-running fit. According to the double-feeding type delivery pump, double-feed delivery can be conducted at the sametime.

Description

technical field [0001] The invention belongs to the technical field of chemical raw material conveying equipment, in particular to a double-feed conveying pump. Background technique [0002] N2H4 (hydrazine), also known as hydrazine and diammonium, is a colorless, fuming, corrosive and strongly reducing colorless oily liquid, highly toxic and unstable, with a pungent smell similar to ammonia odor. It is mainly used as the fuel part of rockets and jet engines, and can also be used as a raw material for pharmaceuticals, such as the synthesis of semicarbazide, isoniazid, nitrofurazone, and hydrazine, and is used in the preparation of salts (such as sulfates) and organic derivatives. NH3 (ammonia gas), is a colorless gas with a strong pungent smell, easily soluble in hydrogenated nitrogen, easy to liquefy, liquid ammonia can be used as a refrigerant, mainly used for nitrogen fertilizer (urea, ammonium bicarbonate, etc.), HNO3, ammonium salt, soda ash, also used to make synthet...
