Problems solved by technology
[0003] At present, many types of chemical grouting pumps are used in the field of chemical grouting in my country, such as: 1) Hand pumps use human power as the power source, which is not suitable for long-term continuous grouting; 2) Grouting pumps with hydraulic pressure as the power source are used There are complex adjustment techniques, high maintenance costs, and sometimes oil leakage, which affect its promotion and use; 3) The chemical grouting pump powered by compressed air has a lagging grouting pressure response during the grouting process, and chemical The penetration of slurry material is not strong; 4) The grouting pump powered by the combination of ordinary AC motor and mechanical deceleration device with one-way rotation drive has chemical slurry material participating in the circulation of the slurry material itself, which is prone to temperature accumulation and affects chemical 5) The grouting pump powered by the combination of ordinary DC motor and mechanical deceleration device with two-way rotation drive, the frequent reversing actions directly affect the service life of ordinary motors

The invention discloses a chemical grouting pump driven by a stepping motor, which comprises the stepping motor (2), a motor shell (3) and a working cylinder barrel (6), wherein the motor shell (3) and the working cylinder barrel (6) are connected together through a big connector sheath (4); the stepping motor (2) is fixed on the motor shell (3); a cavity in the motor shell (3) and the working cylinder barrel (6) is provided with a coupling (22), a feed screw nut (16), a ball screw (14) and a piston (11); and an end face of the working cylinder barrel (6) is fixed with a cylinder barrel cover (10) which is provided with a material hole (9). The chemical grouting pump overcomes defects of various chemical grouting pumps. The chemical grouting pump driven by the stepping motor has the advantages of small volume, light weight, reasonable structure, and convenient use.
Description
technical field [0001] The invention relates to a chemical grouting pump driven by a stepping motor, which is used for anti-seepage or reinforcement of engineering building foundations and needs to be grouted with chemical materials. Background technique [0002] The chemical material grouting treatment process is aimed at cracks or faults in the foundation of engineering buildings, which affect the quality of design and construction. The special properties of chemical materials are used to pour chemical materials into cracks or faults by means of mechanical and physical pressure. After solidification, it can fill and bond cracks or faults, increase the strength of cracks or faults, and make the foundation of engineering buildings meet the design requirements. [0003] At present, many types of chemical grouting pumps are used in the field of chemical grouting in my country, such as: 1) Hand pumps use human power as the power source, which is not suitable for long-term conti...
