The technical scheme adopted is: a central effluent filtering device, which is characterized in that it comprises a water tank, a chip removal water tank, a filtering mechanism, an input pipeline, a connecting pipeline, an output pipeline, a low-pressure delivery pump and a high-pressure delivery pump, and the filtering mechanism comprises a filter and a second filter; One end of the input pipe is connected with the outlet of the waste water recovery channel of the machine tool workbench; The other end of the input pipe is connected with the chip conveyor water tank; Both ends of the connecting pipe are respectively connected with the water tank. The filter and the low-pressure delivery pump are connected and installed on the connecting pipeline. One end of the output pipeline is connected with the water tank, and the other end is connected with the end of the machine tool spindle through a rotary joint; The filter and high-pressure delivery pump are connected and installed on the output pipe. The cooling water in the water tank is delivered to the central through-hole of the main shaft through the high-pressure delivery pump to cool the main shaft. The inclined high-level overflow pipe is connected to the side wall of the water tank, and the bottom end of the high-level overflow pipe is located in the chip cleaning water tank. When the liquid level in the water tank is higher than the top of the high-level overflow pipe, the cooling water will automatically flow into the chip cleaning water tank from the high-level overflow pipe to prevent the water tank from being filled. As a supplement and improvement of the above technical scheme, the utility model also includes the following technical features. The filter is a coarse filter and the second filter is a fine filter. The wastewater recovered from the wastewater recovery channel of the machine tool workbench enters the central through-hole of the spindle through two filters, effectively improving the purity of the cooling water. The wood chip cleaning water tank is separated into two chambers by the filter screen. The input pipe is connected with one chamber, and the connecting pipe and the high-level overflow pipe are connected with the other chamber. The recycled wastewater is filtered by the filter screen first, extending the service life of the filter and the second filter. The central effluent filtering device also includes a liquid level sensor, which is installed in the chip cleaning water tank to detect the liquid level in the chip cleaning water tank. A pressure gauge is connected to the output pipe to detect the pressure of cooling water in the output pipe at any time.

A large number of practices have proved that every 1 degree change in the workpiece temperature during the processing will result in several micrometers of change within the range of 1 meter. The temperature of iron filings produced in high-speed cutting of workpiece on CNC machining center is up to several hundred degrees. In order to avoid the deformation of the workpiece caused by these high-temperature iron chips falling on the surface of the workpiece, it is necessary to quickly reduce the temperature of the iron chips. Generally, the measure we take is coolant, also called cutting fluid. The selection principle of cutting fluid must meet the requirements of cutting performance and service performance, that is, it should have good lubrication, cooling, rust prevention and cleaning performance, and can meet the process requirements during the processing, reduce tool loss, reduce the temperature and roughness of the processing surface, etc. Therefore, the selection of cutting fluid should follow the following principles: First of all, the cutting fluid shall meet the requirements for rust prevention between work procedures and shall not corrode the work pieces. It shall also meet the requirements of equipment lubrication and protection management. In other words, the cutting fluid cannot leave hard colloidal deposits on the guide rail of the CNC machining center, so as to ensure the safety and normal operation of the equipment used. In addition, the coolant selected for CNC machining center shall be free of irritating smell and harmful additives to ensure the safety of users. It also has a good waste liquid treatment method to minimize the impact on the surrounding environment. In terms of service performance, it is necessary to adapt to various processing methods and cooling of various workpiece materials as much as possible, in addition, it should have a long service life. In terms of tools, the production is more smooth. Improve cutting speed and tap more productivity in production. The tool wear is reduced.

The multi-stage centrifugal pump is a vertical structure with a small floor area. The center of gravity of the pump coincides with the center of the pump foot, so it runs stably, has small vibration and long service life

characteristic 1. The multi-stage centrifugal pump is a vertical structure with a small floor area. The center of gravity of the pump coincides with the center of the pump foot, so it runs stably, has small vibration and long service life. 2. The multi-stage centrifugal pump has the same caliber and is on the same horizontal centerline. It can be directly installed in any part of the pipeline without changing the pipeline structure, which is very convenient for installation. 3. The motor plus rain cover can be directly placed outdoors for use without building a pump house, which greatly saves capital investment. 4. The lift of multistage centrifugal pump can meet different requirements by changing the pump stages (number of impellers), so it is widely used. 5. The shaft seal adopts cemented carbide mechanical seal, which is reliable without leakage and has small mechanical loss. 6. High efficiency, energy saving and beautiful appearance. 7.

In daily application, the pressure of hydraulic chuck shall not be too large or too small, which may easily lead to fracture of internal fittings, and too small may lead to failure to clamp the workpiece. So how much pressure is appropriate for our daily use, Generally speaking, the pressure limit of internal fittings of our hydraulic chuck is 3.5Mpa, so the pressure between 4-18 inches of hydraulic chuck is not more than 2.5Mpa, When using the heightening claw, the pressure should be adjusted to half of the original one.

What is the difference between hydraulic chuck and oil pressure chuck? Oil pressure is also called hydraulic pressure, so hydraulic chuck and oil pressure chuck refer to the same thing. Which chuck has better accuracy? In fact, it depends on your use. If the accuracy of the single chuck pneumatic chuck is the best, the current best one can hit 0.5um, but its clamping force is very weak. Therefore, hydraulic chuck, namely hydraulic chuck, is widely used at present
