What kind of grouting pumps does Wode operate?

November 07, 2018


As a relatively good enterprise manufacturer of construction machinery, Zhengzhou Wode has mechanical equipment such as grouting pumps and industrial hoses and refractory mixers. Zhengzhou Wode has more than 20 years of experience in the mechanical equipment industry, which can better explain and design customers and machinery. The grouting pumps currently operated by the company are as follows:

First, piston type grouting pump

During the reciprocating movement of the piston, the piston grouting pump closes the outlet check gate under the action of its own weight and differential pressure, and the inlet check valve opens under the pressure difference. The liquid suction pump Cavity. When the piston is opened inward, the pressure in the pump chamber rises, causing the inlet check valve to close, and the outlet check valve opening to press the liquid into the outlet pipe.

Second, hydraulic high pressure grout pump

The hydraulic high-pressure grouting pump is composed of an electric motor, a gear oil pump, a relief valve, a hydraulic reversing valve block, a cylinder, a working cylinder, a mixer, a fuel tank, a radiator, an oil filter, an inlet and outlet valve, and an electric control box. The hydraulic high-pressure grouting pump directly drives the gear oil pump by the motor. The high-pressure oil outputted by the gear oil pump enters the hydraulic reversing valve block through the overflow valve, and the hydraulic reversing valve block controls the cylinder to reciprocate, because the cylinder and the working cylinder are synchronized. Movement, because the cylinder stroke of the working cylinder is the same as the cylinder, so the displacement and pressure of the working cylinder are basically close to the cylinder. There are a set of suction valve and slurry valve at both ends of the working cylinder, that is, the same slurry can be sucked and discharged. It is also possible to suck up two different slurries separately.

Third, squeeze grouting pump

The squeeze type grouting pump is composed of a roller, a wheel frame, an extrusion hose, a reset guide wheel, a pump body, a transmission device and the like. The rotating wheel frame drives the roller to crush the rubber tube mounted on the inner wall of the pump body, and squeezes and presses the mortar in the tube. The squeezed hose is restored by its own elasticity and the reset guide wheel, so that the inside of the hose is partially vacuumed and a new mortar is sucked in. When the squeeze grouting pump delivers the mortar, the mortar does not come into contact with the metal parts. The squeeze type grouting pump has the advantages of simple structure, convenient use and adjustable displacement, and the disadvantage is that the extruded hose has a short service life, a low conveying height and a short distance.

The squeeze grouting pump can not only pump high-concentration and high-viscosity materials such as mortar, cement slurry and pulp, but also can be sprayed with air compressors and spray guns. Extrusion grouting pump is ideal for grouting of mine shaft, iron road tunnel, hydropower project, rock slope, underground engineering, subway and municipal construction, as well as blast furnace spray repair and building wall spraying in steel and chemical industry. equipment.
