The Filter Press pump is summarized as a special pump specially used for the filling and feeding of the filter press.
When the filter press feeds, it can realize large flow and small flow according to the change of feed resistance of the filter press.
When using a filter press pump, there are many details that need to be paid attention to, ignoring one detail may lead to the scrapping of the entire filter press Filter Press Feed Pump,Slurry Pump For Water Filter,Filter Press Feed Pump Selection,Pump For Pneumatic Diaphragm Shenzhen Hongfa Environmental Protection Equipment CO., LTD , https://www.hongfafilterpress.com
In fact, the working principle of the filter press pump is very simple. The general principle is to adopt a unique hydraulic and impeller installation method.
1. Before starting the filter pump, inject liquid into the pump, close the valve at the outlet and turn on the power.
This step is to discharge the gas from the filter press pump, which is the same principle as other pumps, otherwise the pump will be full of other open filter press pumps, which will cause the pump to run dry and burn out.
2. After turning on the power, check whether the steering of the filter press pump is correct. Generally, the steering of the filter press pump is seldom fixed, so you need to check this problem when you run it.
3. The machine runs for 5 to 10 minutes for trial operation, and it runs normally when there is no abnormal phenomenon.
4. After the work is finished, when you are ready to close, first close the valve at the outlet, and then discuss disconnecting the power supply.
Rebar Bending Testing Machine (RBT165A) Three Point Bending Test
**Rebar Bending Testing Machine (RBT165A) - Three Point Bending Test**
This advanced testing machine is specifically designed for conducting bending tests on various metallic materials, including rod steel, plate steel, and threaded steel. It features a dual-direction hydraulic loading system, making it easy to bend specimens with diameters under 40mm up to 180°. The support roller span can be adjusted manually using a hand wheel, which drives a dual-direction screw mechanism. The self-locking design of the support rollers eliminates the need for any tools to tighten them, while the plug-in mandrel allows for quick and simple changes.
The equipment also offers speed adjustment and real-time display of displacement and speed, ensuring compliance with ISO 7438:2005, Clause 6.3, which specifies a test rate of (1 ± 0.2) mm/s in case of disputes. It provides real-time monitoring of the bending angle, making it ideal for various bending tests.
**Key Features:**
1. The horizontal structure with a height of 900mm ensures ease of operation.
2. Two support rollers and a mandrel first bend the specimen to 180°, followed by the main cylinder returning. The vice cylinder and two compression plates then complete the bending process, guaranteeing accurate results that meet standard requirements.
3. A displacement transducer measures and transfers data to a microcomputer, displaying test speed, piston displacement, and bending angle on an LCD screen.
4. Manual control of the cylinder action ensures user-friendly operation and high efficiency.
5. Powered by hydraulic loading and motor-driven systems, the machine has a compact design, low noise, and high reliability.
6. Safety is ensured with protective shields that prevent injury from flying specimens.
7. A manual hand wheel allows for easy adjustment of the support roller clearance, accommodating different specimen sizes and shapes, along with interchangeable mandrels.
