Product Description


JP70 type, JP60 type, JP50 type, JP50Q type, JP40 type and JPR70 type are general-purpose mortar pumps and sprayers. Wen Gong introduced German PUTZMEISTER technology in the 1990s and used it for various cement-based and gypsum-based applications. Polymer-like mortar includes: plastering mortar, fiber mortar, UHPC concrete, ECC concrete, thermal insulation mortar, refractory mortar, bonding mortar, facing mortar, interface mortar, self-leveling mortar, waterproof mortar, anti-corrosion mortar, masonry mortar, Pressure conveying, grouting, and spraying machinery for reinforcing mortar, filling mortar, and grouting materials are widely used in grouting and mortar spraying for building facade spraying, concrete 3D printing, wind power generation, steel smelting, facility maintenance of road bridges, and tunnel projects. It is an important equipment and necessary instrument for the construction of polymer mortar materials in various construction projects.
General-purpose mortar pumps and sprayers have large displacement, adjustable flow, high pumping pressure, and long distance, and can easily pump mortar containing a certain amount of aggregates with a particle size of less than 6 mm. What makes it unique is the following structural advantages:
The main motor of the screw pump is provided by the German NORD company. The biggest feature of this motor is that the motor efficiency and motor power factor are both internationally advanced indicators. In addition, according to user needs, we can choose to configure domestic high-quality servo motors, Y2 series asynchronous motors, and internal combustion engines as prime movers.
The supporting main motor transmission is divided into mechanical stepless transmission, frequency modulation, and winding technologies to choose from. The common features of the reducers are high-strength gear combinations, wear-resistant, high-temperature resistance, reinforced radial and axial output bearings, and high-precision sealing. device.
The stator (also known as the rubber sleeve) of the screw pump is made of polymer materials combined with pure natural rubber. It has passed the infrared spectrum comparison and comprehensive test (analysis report document) by the Key Laboratory of Polymer Science and Technology of Northwestern Polytechnical University (National Rubber Material Testing Unit) No.: Northwestern Polytechnical University NO: F2013022), it was concluded that the rubber material of the screw pump stator is similar to that of similar foreign products.
The machine is equipped with a unique screw pump (rotor, stator) that allows you to instantly load and unload guide rails on site, update and disassemble the screw (pump rotor, stator), and there is no need to be cumbersome or overwhelmed.
The unique drive shaft design uses high-strength hexagonal steel that resists bending and torsion as the main shaft and is equipped with intermittent spiral plates (different from winding spiral belts). Both ends are equipped with high-strength stainless steel cross-joints formed by pressure precision casting, which not only has good self-aligning transmission Function, and has the function of repeatedly stirring the slurry twice to ensure that the mortar in the silo does not segregate, precipitate, or bleed, and can improve the thixotropy of the mortar.
The nozzle (pressure gauge seat) is made of high-strength stainless steel pressure precision casting. It is not only wear-resistant and anti-corrosion, but also has a smooth inner cavity to reduce the resistance of the slurry passing through, ensuring no slurry and smooth discharge.
The special driving component sealing mechanism includes multi-stage adjustable sealing rings, double combined sealing rings, moving water retaining rings, and drainage channels, thereby ensuring that the drive variable speed motor is not penetrated by slurry and the transmission gear is not damaged.
Unique anti-wear technology for electronically controlled screw pumps (stators and rotors). In order to avoid excessive wear of the machine during operation and improve its anti-wear capabilities, an anti-wear limit mechanism is set up to effectively extend the service life of the screw pump.
Among them, the JP50Q is a lightweight spraying machine. Its technical performance is the same as that of the JP50. It is different from the model in terms of appearance and size, and is lightweight and lightweight. Only 2-3 people can lift the whole machine and move it, making it extremely convenient to use.
