Abstract
The utility model discloses a vacuum pump for spinning, which comprises a tank body, wherein a centrifugal pump is installed in the tank body, a water inlet pipe is connected with a water inlet of the centrifugal pump, and a water outlet pipe is arranged at the upper end of the tank body. In the vacuum pump provided by the utility model, water is used for vacuum-pumping and can be used circularly, so that the vacuum pump is water-saving; and compared with vacuum pumps performing vacuum-pumping with oil, the vacuum pump has lower cost, high vacuity, stable performance and safer operation.
Description
Technical field
The utility model relates to a kind of reeling off raw silk from cocoons and uses device, mainly is that a kind of reeling off raw silk from cocoons used vacuum pump.
Background technique
The existing vacuum pump that is used for reeling off raw silk from cocoons all is a sliding valve vacuum pump, and it is to utilize oil to vacuumize, and not only fuel consumption is big, and degree of vacuum is low; If guiding valve does not have good mass balance, can produce bigger vibration in the running.
The model utility content
Technical problem to be solved in the utility model provides a kind of reeling off raw silk from cocoons and uses vacuum pump, and it utilizes water evacuation, and can be recycled, using water wisely, and to vacuumize cost lower for oil relatively, the degree of vacuum height, smooth performance is operated safer.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of reeling off raw silk from cocoons used vacuum pump, includes tank body, in the described tank body centrifugal water pump is installed, and the water inlet of described centrifugal water pump is connected with intake pipe, and there is outlet pipe the upper end of described tank body, is equipped with in the outlet pipe to filter sponge.
Centrifugal water pump is a kind of water lifting machinery that utilizes the centrifugal motion of water in the utility model.Prestart should be filled water earlier in pump, the impeller of starting back rotation drives the water high speed rotating in the pump, and water is made centrifugal motion, outwards throws away and be pressed into outlet pipe.After water was thrown out of, near the pressure the impeller reduced, and just forms a low pressure area near rotating shaft.The pressure here is more much lower than barometric pressure, and the water of outside just under atmospheric effect, is washed bottom valve open and entered in the pump from intake pipe.The water of rushing in is thrown out of again in the impeller high speed rotating, and is pressed into outlet pipe.Impeller is continuous high speed rotating under power engine drives, and water just is pumped to eminence from lower continuously.
The utility model has the advantages that:
The utility model utilizes water evacuation, and can be recycled, using water wisely, and to vacuumize cost lower for oil relatively, the degree of vacuum height, smooth performance is operated safer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of reeling off raw silk from cocoons used vacuum pump, includes tank body 1, and centrifugal water pump 2 is installed in the described tank body, and the water inlet of described centrifugal water pump 2 is connected with intake pipe 3, and there is outlet pipe 4 upper end of described tank body 1, is equipped with in the outlet pipe to filter sponge.
Claims (1)
