High quality colloidal grouting pump system for sale
High quality colloidal grouting pump system for sale are usually not the first choice for grout service. In addition to wear, it can be difficult to handle the wide range of pressure outputs often required. Some grout mixers use similar pumps, but they operate at near constant speeds. Due to its limited use, it is not worth elaborating here. The colloidal grouting pump system for salehas pistons that reciprocate in a tightly fitted cylinder. The ones used for grout are usually double-acting. While the piston is moving in one direction, it ejects the grout and a suction is formed on the opposite side, pulling in the grout in preparation for the next ejection stroke. A check valve is required to close the outflow port while the inflow is taking place, and vice versa. The basic layout is shown in the figure.
The grout flow to the pump comes from the bottom left. Pumped discharge exits from the top to the right. The piston stroke is on the right side. The arrow shows the flow. Ball valves are shown (see below for other types of valves). The valve on the upper right is lifted from the seat by the pressure from the piston through the grout, and the valve on the lower left is also on the back side of the piston in this case. This will return the grout to the cylinder and prepare for the return stroke. The other two valves are closed for now.
In this particular arrangement, the grout can only access the outer ends of the two pistons. The space in between is occupied by air or hydraulic driving fluid. The high pressure cement mixed grout pump plant indicates that the piston is moving to the right and the grout flow is indicated by the arrow.
The colloidal grouting pump system for sale are usually more compact and portable than pumps with external motors. Pumps with two or more cylinders, like car motors, tend to line up cylinders whose pistons are driven by a crankshaft. When working hard, most of them vibrate and must be firmly anchored to the engine bed or other substantial base.
Motors for colloidal grouting pump system for sale can be reciprocated, placed between pistons as shown, or separated to operate the pistons directly or through a mechanism. We can use air, hydraulic, electric, or internal combustion motors. However, to get the required variable output, motors that give a constant speed, such as electric motors and some internal combustion motors, must have a variable speed drive between them and the pump. These drives are usually hydraulic and housed in large, heavy boxes, making it difficult to move the pump in the field. Therefore, they tend to be mostly used in large pumping stations rather than moving near grout holes. The power required for a high pressure cement mixed grout pump plant clearly ranges from just a few horsepower to hundreds of horsepower, depending on capacity. Required Output Pressure Available outputs range from small to very large as well.
