Tube Single Piston Pump

Abstract

The invention discloses a tubular single-plunger pump, relates to a plunger pump, and aims at providing a tubular single-plunger pump which is compact in structure, high in efficiency, not prone to be blocked and good in sealing property. The tubular single-plunger pump comprises a base, a plunger pump oil cylinder, a water cooling device, a plunger barrel, a material jar, two sliding gate plates and a plunger head matched with the plunger barrel; the material jar, the plunger barrel and the water cooling device are fixed to the base, a piston rod is arranged in the plunger pump oil cylinder, the front end of the piston rod is connected with the plunger head arranged in the plunger barrel, and the water cooling device is arranged between the plunger pump oil cylinder and the plunger barrel and can cool the plunger pump oil cylinder and the plunger barrel; one end of the material jar is connected with the plunger barrel, the other end of the material jar is provided with a discharging port, and the upper portion of the material jar is provided with a feeding port; the two sliding gate plates are arranged at the discharging port and the feeding port respectively.

Description

technical field [0001] The invention relates to a plunger pump, in particular to a tubular single plunger pump. Background technique [0002] Solid pumps are used to pump media containing a large amount of foreign matter and dry materials. Tube single plunger pumps are specially used to pump sludge, toxic or corrosive, semi-liquid or paste-like media that are difficult to pump. The existing single plunger pump is generally composed of a hydraulic cylinder, a material cylinder, a check valve and a hydraulic station. When conveying solid materials, the check valve is prone to blockage, which affects the conveying of materials. At the same time, due to poor sealing performance, it is easy to cause material leakage. In addition, due to long-term work, the friction between the plunger barrel and the plunger pump cylinder generates heat, which affects the normal operation of the plunger pump.
