Description
Technical Field
The utility model relates to a unhurried current device, in particular to pump sunction inlet unhurried current device.
Background
In the machining industry, a high-pressure pump used for supplying liquid to a machine tool generally has a separate water tank for mounting the high-pressure pump, and the precision of the cutting fluid in the water tank is required to be kept about 30 μm, and the high-pressure pump generally directly sucks the liquid from the water tank through a suction pipe, as shown in fig. 4. The high-pressure pump is generally a screw pump or a gear pump, is expensive, and inevitably generates small bubbles in the water tank once the high-pressure pump is damaged and the maintenance cost is very high and the cutting fluid in the water tank is usually filtered by several stages and then conveyed into the water tank; meanwhile, fine particles smaller than 30 mu m enter the water tank along with the cutting fluid, hardened particles are deposited at the bottom of the water tank after a long time, and if the hardened particles are not cleaned in time, the hardened particles are possibly sucked into a pump cavity to abrade a screw or a gear.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the not enough of above-mentioned prior art existence, provide a pump sunction inlet slow flow device that can prolong high-pressure pump life.
The utility model provides an above-mentioned technical problem's technical scheme as follows: a pump suction inlet slow flow device comprises a device body and a connector, wherein the device body is a cylindrical or hollow prismatic shell, one end of the device body is closed, the other end of the device body is provided with the connector, and the side wall of the device body is provided with at least one cutting fluid inlet.
Further, the connector is cylindrical and is coaxial with the device body.
Furthermore, a threaded hole is formed in the side wall of the connector.
Further, the device body is a hexagonal prism-shaped shell.
Furthermore, 3 cutting fluid inlets are formed in the hexagonal prism-shaped shell, and the 3 cutting fluid inlets are uniformly distributed along the central axis of the hexagonal prism-shaped shell.
Further, the 3 cutting fluid inlets are respectively disposed on the edge lines of the hexagonal prism-shaped housing and are respectively symmetrically disposed about the corresponding edge lines.
Further, 3 cutting fluid inlets are respectively rectangular structures.
The utility model has the advantages that:
1) the slow flow device is arranged at the suction end of the pump, the cutting fluid enters the pump through the connector after passing through the cutting fluid inlet, and the cutting fluid generates a certain flow velocity in the prismatic shell, so that the precipitation and hardening of small particles in the water tank in the device are reduced;
2) because the water pump is in the working process, vacuum is formed in the pump cavity along with the high-speed rotation of the water pump, water in the water suction pipe flows into the pump cavity under the action of atmospheric pressure to quickly fill the vacuum area, vacuum is formed in the water suction pipe at the moment, cutting fluid in the water tank can quickly fill the water suction pipe, the flow rate of water flow around the inlet of the water suction pipe is accelerated, and if sediments exist at the bottom of the water tank, the sediments hardened at the bottom can be taken up and sucked into the pump cavity; after the device is adopted, the cutting fluid enters from the side wall, so that the disturbance of the fluid to the sediment at the bottom of the water tank is reduced, and the sediment at the bottom can be prevented from entering the pump cavity;
3) because one end of the prismatic shell is closed, the pressure of the suction inlet of the water pump is dispersed to a plurality of cutting fluid inlets on the side wall of the prismatic shell, so that the flow speed of the cutting fluid in the water tank entering the device is reduced, bubbles and small particles are better released and deposited before the cutting fluid enters the device, the damage to the water pump can be reduced, and the service life of the water pump is prolonged.
