Embodiment 1

[0028] Example 1: Combining Figure 1-Figure 8 As shown, the fluid end of the detergent slurry delivery pump of the present invention mainly adopts the approach of multi-cylinder double-acting, so that the single-acting work of the plunger is changed to double-acting work. This embodiment takes three-cylinder double-acting as an example, of course according to It can also be designed as two-cylinder double-acting, five-cylinder double-acting, seven-cylinder double-acting, etc. It specifically includes: combined pump body, box body positioning sleeve 3, combined sealing box body 4, fully open liquid inlet liquid collector 5, combined valve 6, packing assembly 7, ball connecting box 8, plunger 12, etc., among which :

[0029] Combined pump body. The first pump body 1 and the second pump body 2 are assembled and welded through the body positioning sleeve 3 (cylinders according to the number of cylinders) between them, and the 5 groups of fully open liquid inlet collectors are we...

Embodiment 2

[0036] Embodiment two: see Figure 9-Figure 11 As shown, the main difference between it and Embodiment 1 is that the location of the liquid inlet collector 5 is different. The liquid inlet collector 5 of this embodiment is arranged on both sides of the first pump body 1 and the second pump body 2. Around the positioning sleeve of the box body at the position of the center line of the plug, it can also achieve the purpose of smooth liquid intake and convenient exhaust. The medium surrounds the outer ring of the box body positioning sleeve, which is conducive to heat dissipation.

Abstract

The invention discloses a fluid end of a detergent slurry conveying pump. The fluid end of the detergent slurry conveying pump adopts a multi-cylinder double-action structure type, the fluid end of the detergent slurry conveying pump comprises a combined pump body, a combined sealing box body, a plunger, a combined valve and a fully-opened liquid inlet collector, wherein the combined pump body isof a double-action pump body structure composed of a first pump body and a second pump body; the plunger is of a double-acting stepped plunger structure and is provided with two sections with different outer diameters, one section of the small outer diameter is located at the front part of the plunger and corresponds to a composite sealing filler in the inner hole of the combined sealing box body,one section of the large outer diameter is located at the rear part of the plunger and corresponds to a sealing filler; and each plunger corresponds to two hemispherical combined valves, liquid inletvalves and liquid outlet valves are both arranged on the hemispherical combined valves, the liquid outlet valve is arranged on the upper portion of the combined valve, and the liquid inlet valve is arranged in the lower portion of the combined valve. According to the fluid end of the detergent slurry conveying conveying pump, the problem that an existing high-viscosity washing powder slurry pumpis low in efficiency, high in pump type, high in noise, difficult to maintain, and high in manufacturing cost can be effectively solved, the pump can be used for conveying high-viscosity media and canalso be applied to the fields of oilfield water injection, boiler water supply and the like for conveying high-pressure liquid.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a fluid end of a detergent slurry delivery pump. Background technique [0002] In the daily chemical detergent industry, the production process of washing powder is mainly to make the raw materials of washing powder into raw slurry, homogenize the slurry into slurry through the reciprocating slurry pump, and input the slurry to a high tower through the nozzle for high-pressure spraying. , the atomized slurry sinks from the upper part of the tower. Because the temperature is set in the tower, it is dried layer by layer and formed into small particles, which are then crushed and screened into washing powder. In the process of making washing powder, the reciprocating slurry delivery pump is the core equipment and plays a pivotal role. At present, the slurry conveying pumps in the complete sets of equipment of domestic and foreign washing powder manufacturers are all reciprocating slu...
