Technical Field
The invention relates to the technical field of pump materials, in particular to a novel material for a mash pump.
Background
The mash pump is mainly used for obtaining liquid (the liquid comprises a fermentation product, a fermentation culture solution and some intermediate products) after fermentation, and mainly refers to a delivery pump of waste residue or waste liquid left after raw materials are fermented in the fermentation industry.
The currently used mash pump preparation materials are mainly divided into two types, one is a common carbon steel material; the other is stainless steel material. No matter the mash pump that ordinary carbon steel made is from wearability or corrosion resistance, its performance is all relatively poor, and life is shorter, and does not conform to relevant food hygiene requirement, and the mash pump that stainless steel material made all has better promotion for its wearability and corrosion resistance of the mash pump that ordinary carbon steel made, and average life has also reached about 2 times of carbon steel mash pump, but its cost of manufacture is higher, whole cost is equivalent to 4 ~ 5 times of carbon steel mash pump, therefore economic benefits is poor.

After the preparation, a sample was taken and the mechanical properties of the novel material were determined as in example 1 of table 1.
Example 2
Preparing a novel material of a mash pump, wherein the novel material of the mash pump comprises the following chemical components in percentage by weight: c: 0.50 wt%, Ni: 5.0 wt%, Cr: 13.0 wt%, Mo: 2.0 wt%, Co: 0.5 wt%, P: 0.01 wt%, S: 0.01 wt%, the balance being Fe.
After the preparation, a sample was taken and the mechanical properties of the novel material were determined as in example 2 of Table 1.
Example 3
Preparing a novel material of a mash pump, wherein the novel material of the mash pump comprises the following chemical components in percentage by weight: c: 0.55 wt%, Ni: 6.0 wt%, Cr: 09.0 wt%, Mo: 2.1 wt%, Co: 0.6 wt%, P: 0.03 wt%, S: 0.03 wt%, the balance being Fe.
After the preparation, a sample was taken and the mechanical properties of the novel material were determined as in example 3 of Table 1.
In addition, the mechanical property data measured by the mash pump made of carbon steel and the mash pump made of stainless steel at present are taken as comparison references, and the specific data are shown in the carbon steel and the stainless steel in the table 1. The carbon steel mainly contains Fe with the carbon content of 0.8-1.2 wt%, while the stainless steel mainly contains Fe with the following contents of other elements: c: 0.30-0.80 wt%; ni: 9.0-11.0 wt%, Cr: 18.0-20.0 wt%.
Table 1 shows the mechanical properties and hardness test results of examples 1 to 3 of the present invention and carbon steel and stainless steel materials.
| Name of Material | High tensile strengthDegree (MPa) | Yield strength (MPa) | Hardness of | Impact force (J/cm2) |
| Carbon steel | 235 | 235 | 35-39 | 18 |
