Custom production of pneumatic conveying air pumps with complete certification.
$面议(定制)
Category: Machinery & Equipment/Packaging Related Equipment/Other Packaging Equipment
Company: North Pressure Vessel (Jinan) Co., Ltd.
Product Description: I. Definition of a Blow Tank:The blow tank is a device used for conveying powdered and granular materials (suitable media: powder, coal, ash). The working process involves storing the material in the tank body of the blow tank, fluidizing the material with compressed air, and then conveying it through a pipeline to the destination under the action of a pressure differential.II. Working Principle of the Pneumatic Conveying Blow TankIn the pneumatic conveying process, the blow tank plays a crucial role. The specific working process can be broadly divided into the following three steps:Process 1: Feeding. Material first enters the blow tank body through the feed inlet. Feeding is typically completed via an automated feeding device (conveyor), but manual feeding is also possible. When the material level in the tank reaches a certain point, the feeding action is completed.Process 2: Fluidization. During the material conveying stage, compressed air enters the blow tank body through a fluidization device at the bottom (such as an aeration pad or fluidizing nozzle). The fluidization device ensures that compressed air is evenly distributed at the bottom of the material, causing it to become fluidized. In this fluidized state, the material can flow like a liquid under the push of air pressure.Process 3: Conveying. After the material is fluidized, the discharge valve opens. The internal pressure of the tank is higher than that in the conveying pipeline. Under the action of the pressure differential, the fluidized material is pushed into the conveying pipeline. Within the pipeline, the material is conveyed as a gas-solid two-phase flow, meaning the material particles are suspended in the air stream and move forward with the airflow, eventually reaching the destination.The above describes the complete working process of a pneumatic conveying blow tank, which can significantly improve the efficiency of material conveying, making the entire process more energy-efficient and environmentally friendly, while also saving substantial labor. Selecting a blow tank requires expertise; different conveying media have varying material properties, with different requirements for temperature resistance, wear resistance, and corrosion resistance. Different production conditions also demand different blow tank sizes, making it particularly important to choose a service provider with extensive experience in pneumatic conveying projects. Northern Pressure Vessel (Jinan) Co., Ltd. has experience in project design, manufacturing, and installation, serving leading enterprises in various fields such as power, energy, petroleum, and coal chemical industries, with strong professional service capabilities. Business owners in need are welcome to inquire about cooperation. more>

Its drive motor can be started either by a clutch or controlled by a variable frequency speed regulation system, ensuring smooth startup. Power is transmitted to the drum via a V-belt, driving the drum to rotate at high speed around its own axis, forming a centrifugal force field. The material to be separated enters the high-speed rotating drum through the upper feeding pipe. Under the action of the centrifugal force field, the material is evenly distributed on the drum wall for the centrifugation process. The liquid phase passes through the gaps of the solid material and the filter bag, is thrown out through the drum holes into the shell cavity, and discharged from the liquid outlet at the base. The solid material is retained in the filter bag. After shutdown, the machine cover is opened (with the help of a specially designed balance assist device), the locking bolt of the flange cover is pulled out, and the filter cake is lifted out to a designated location for unloading using a special lifting tool, thus completing a work cycle.

40mm Rebar Coupler with Right and Left Hand Threads
$7.8
Category: Metallurgy & Minerals/Common Steel/Rebar
Company: Hengshui Keyuan Rebar Connection Equipment Co., Ltd.
Product Description: What to do if the rebar coupling sleeve cannot be screwed on? During the construction process of rebar connections, it is common to encounter situations where the rebar coupling sleeve cannot be screwed onto the threaded end. The reasons for the rebar coupling sleeve failing to screw on include the following: First, the thread pitch of the internal threads in the rebar coupling sleeve differs from the thread pitch of the rebar threaded end. The thread pitches of rebar coupling sleeves produced by Hengshui Keyuan Rebar Connection Equipment Co., Ltd. are as follows: The thread pitch for Φ16, Φ18, Φ20, and Φ22 rebar coupling sleeves is 2.5mm. The thread pitch for Φ25, Φ28, Φ32, and Φ36 rebar coupling sleeves is 3.0mm. The thread pitch for Φ40 rebar coupling sleeves is either 3.0mm or 3.5mm. Second, the thread angle of the rebar coupling sleeve differs from the thread angle of the rebar threaded end.    The thread angles of rebar coupling sleeves produced by Hengshui Keyuan Rebar Connection Equipment Co., Ltd. are 75° and 60°, which are commonly used in the market. Some companies produce sleeves with a thread angle of 70°, but this is an isolated occurrence. Third, the rebar threaded end has been threaded too large. During the threading process, errors may occur due to insufficient adjustment precision of the threading machine, resulting in an oversized rebar threaded end. Alternatively, if the threading machine's gear disc is not tightened properly or the eccentric shaft shifts, it can cause the rebar threaded end to become oversized. If not promptly tested with a ring gauge or rebar coupling sleeve, the prefabricated rebar threaded end may be significantly oversized. In such cases, the only solution is to have the rebar coupling sleeve manufacturer produce an enlarged sleeve to match the oversized threaded end. Hengshui Keyuan Rebar Connection Equipment Co., Ltd. can produce enlarged sleeves tailored to the threaded ends provided by customers, with fast turnaround and high efficiency.
