Double Plunger Hydraulic Grout Pump
In the United States, grout pumps of a progressive helical cavity design have in the past been preferred by many agencies for foundation grouting applications. These mechanically simple pumps produce a continuous feed with little pressure variation and with relatively low likelihood of plugging or breakdown that might cause interruption in the grouting operation. However, high wear rates on the rubber stator and steel rotor-especially if sanded grout mixes are used can lead to relatively high maintenance costs. Progressive cavity pumps sometimes are equipped with a stick-shift, automobile-type transmission; this transmission faciliates achieving the desired grout flow rate over a wide range of pressures. Rheostats accomplish a similar function for electrically operated pumps.However, the simplest way to compensate for excessive pump discharge is to provide a short bypass line from the pump back to the agitator. Multiple-stage pro
Central Grout Mixing and Grout Pump Plants
As mentioned earlier, there are sites where carrying out all the grout mixing in one centralized location is obviously best. Examples include deep canyons without convenient access down the bottom, some underground work, sites where access around the job is too restricted to permit economical transport of bagged cement, and so on. In these, a central grout mixing plant sending the grout off in lines to agitators and grout pumps elsewhere can be a good solution. And, of course, setting up bulk cement facilities is usually worthwhile at such plants. The next stage in the use of centralized equipment is the central grout pumping plant; this not only mixes the grout but also pumps it off to the holes through circulation lines. The concept comes from chemical grouting where some quite complex plants have been used, particularly where the grouting has been in a compact area and has required intensive placement of holes, an example being tunnel grouting.

The service life of tube pump follows pump fast run the connection between
Tube pump is a kind of very economic tool, got applied between very much industry territory, but to using person for, they are being bought with the choice the unidentified Bai Zhi that there still is a lot of above this pump machine is in, store of plant of the facility that note an oar takes you to understand the making production methods of next tube pump, so that user people can choose the product that fits oneself. 1, slippery boots type is designed (pump of tube of slippery boots type) , tube becomes U appearance or arched state in pump antrum; Two or the slippery boots of two above (slide block) runner be been in by fixed installation (arm) go up, it is with what slide means compresses tube. Runner every rotate a week compresses tube 2 times or for many times (depend on slippery boots amount) . This kind of slippery dynamic pressure shrinks means, it is particularly big to the harm of tube, the car that is just like high speed travel is abrupt slam the brakes on, go
Customization of grouting machine
Cement mixers and mixer is designed for cement mixing, in ground/grouting in underground engineering.It can produce various types of grout, such as water, cement, bentonite and additive mixing machine mixing, and then mixed slurry can be stored in a blender, therefore, the mixed work can do. It is made of cemented stone made of concrete, not only hardened high strength, but also resistant to fresh water or salt water erosion. For a long time, cement is an important cementitious material, widely used in civil engineering, water conservancy, national defense and other projects. We can effect shipment on august diesel cement grouting pump and Jordan. Now our high pressure hydraulic cement grouting pump and mixer, blender in his work site. He is very happy, to show us some pictures. My clients are doing dam project in Jordan. Our engineers design according to customer's requirements on output and pressure grouting machine. We have many ty
Cement grouting pump factory
1. The cement grouting machine should be placed as far as possible in a horizontal position to avoid twisting and discounting of the oil pipe and the suction pipe. The suction pipe should be as short as possible, and its vertical distance should not exceed one meter. 2. Regularly check the fuel tank strainer, oil strainer screen, and perform cleaning. Replace the hydraulic oil regularly. It is recommended to replace the hydraulic fluid once a month or so. The cement grouting machine uses No. 68 hydraulic oil in summer and No.46 hydraulic oil in winter, about 45 kg of hydraulic oil per change. 3, The work site should have sufficient water to facilitate work. 4, The hydraulic joints should be checked regularly and shall not be loosened. 5. Cement grouting machine construction operators must have certain grouting experience to ensure smooth construction operations. 6, The electric control box, motor and electrical appliances should be kept clean and dry, and often check the above part
Grout mixer machine factory
High temperature season grouting mixer machine construction should use a damp cloth cover or wet bag to cover the duct. Avoid strong light exposure. Construction of the application of insulation materials in the low temperature season wrapped around the duct. We should pay attention to prevent the tube grouting pump by freezing. And we also should to ensure that the grouting pump slurry temperature. When the level of delivery of more than 200 meters or the vertical height of more than 40 meters, you must choose a reasonable method of piping and pumping process. Vertical delivery pipe down or inclined pipe horizontal pipe layout in front of, suitable for large diameter grout mixer machine pipe pump and long conical pipe, the use of elbows and hoses. Management should regularly check the pipeline, especially the Elbow and other parts of the wear and tear, to prevent pipe explosion. Grouting mixer machine pipe should be based on engineering and construction
China pneumatic concrete grouting pump
Concrete is collectively referred to as engineering composite materials that are made from cementitious materials that bond together the aggregate. The term concrete is usually used to refer to the use of cement for cementitious materials, sand, stone aggregate. And water,which can contain additives and admixtures,according to a certain percentage, by mixing the resulting cement concrete. Also known as ordinary concrete, it is widely used in civil engineering. Inorganic cementitious materials, such as cement, lime, gypsum and the like, are mixed with water to make the concrete mixture plastic, and then to be hardened by chemical and physical chemical action to produce strength. In general, drinking water can meet the requirements of concrete mixing water. Excessive acids, alkalis, salts and organic matter in the water can have detrimental effects on the concrete. Aggregates not only have a filling effect, but also have an important influenc
Tube pump and the advantage that other pump compares
Tube pump is a kind of technology with global the rapiddest development, connecting general reason condition to fall, chemical corrosives is eroding the valve of membrane pump and odd screw, sealed, rotor, athletic component, cause the damage of pump thereby, cause production to interrupt, and tube pump does not have valve, won't arise divulge, mechanical component is done not have on product line. Discharge is contacted with wall or conduit photograph only, and the cost of pipe is very low, safeguard little, and very durable. The discharge of tube pump and rotate speed become direct ratio, tube pump does not have check valve, also eliminated create metric inaccurate source, because this won't produce gas lock phenomenon. And there is valve inside membrane pump, produce card likely also to live, jam phenomenon, (because of ball valve or valve base caustic) , cause discharge to change, , can destroy the consistency of end item or the difference that cause product quality t
