Tube type double plunger pump

Abstract

The invention discloses a tubular double-plunger pump, relates to a plunger pump, and aims at providing a tubular double-plunger pump which is compact in structure, stable in discharge capacity, high in efficiency, not prone to be blocked and good in sealing property. The tubular double-plunger pump comprises a base, a main discharging port and two plunger pump main bodies fixed to the base in parallel; each plunger pump main body comprises a plunger pump oil cylinder, a water cooling device, a plunger barrel, a material jar, sliding gate plates and a plunger head matched with the plunger barrel, wherein 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, 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, the upper portion of the material jar is provided with a feeding port, and the discharging port and the feeding port are each provided with one sliding gate plate; the two discharging ports formed in the two plunger pump main bodies are connected with the main discharging port.

Description

technical field [0001] The invention relates to a plunger pump, in particular to a tube type double plunger pump. Background technique [0002] Solid pumps are used to pump media containing a large amount of foreign matter and dry materials. Tube plunger pumps are specially used to pump sludge, toxic or corrosive, semi-liquid or paste-like media that are difficult to pump. The plunger pump is generally composed of a hydraulic cylinder, a material cylinder, a check valve and a hydraulic station. The existing single plunger pump has the following problems: when conveying solid materials, the check valve is prone to blockage, which affects the conveying; the sealing performance Not good, it is easy to cause material leakage; due to long-term work, the friction between the plunger barrel and the plunger pump cylinder will generate heat, which will affect the normal operation of the plunger pump; the capacity of the single plunger pump is small, the material pumping will be inter...
