Background
At present, a conventional self-priming pump is shown in fig. 2, and a positive impeller and a secondary impeller are required to work simultaneously to realize liquid pumping operation, so that the consumed power is high, and the energy conservation and the environmental protection are not facilitated; and the pump shaft of the whole self-priming pump is longer after adopting the driving mode of the positive and auxiliary impellers, not only is not beneficial to reducing the volume, but also is not beneficial to reducing the vibration generated by the self-priming pump during working. Therefore, an energy-efficient vertical self-priming pump is needed to solve the above problems.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide an energy-conserving vertical self priming pump of high efficiency that energy-conserving effect is obvious and long service life.
The purpose of the utility model is realized like this:
the utility model provides an energy-efficient vertical self priming pump, includes the bottom plate that is fixed in on the base, install the barrel on the bottom plate, be provided with on the upper portion lateral wall of barrel and annotate the liquid mouth, be provided with the tapping hole on the lower part lateral wall of barrel, the pressfitting has the pump cover on the spiral case water pressure chamber of installation in the barrel, and spiral case water pressure chamber separates the cavity of barrel for two upper and lower mutual cavities that communicate, be provided with import and export on the lateral wall of barrel, and import and export are linked together with spiral case water pressure chamber respectively, and the impeller is installed through impeller nut in one of spiral case water pressure chamber to the pump shaft plug-.
The utility model relates to a high-efficiency energy-saving vertical self-priming pump, the shaft sleeve is sleeved on one end of the pump shaft, which is positioned outside the water pressure chamber of the volute, the mechanical seal is sleeved outside the shaft sleeve, a mechanical seal cover is pressed on the mechanical seal through a union cap on the pump shaft, and the mechanical seal cavity formed by the mechanical seal, the mechanical seal cover and the shaft sleeve is filled with seal filler;
the utility model relates to a vertical self priming pump of energy-efficient, install a drive arrangement on the barrel, drive arrangement's axis of rotation passes through shaft coupling drive pump shaft.
Compared with the prior art, the beneficial effects of the utility model are that:
compared with the conventional self-priming pump, the self-priming pump has the advantages that the auxiliary impeller is omitted, the shaft power is greatly reduced, and the energy-saving effect is achieved. For example, the pump matched with a 22kw motor can save electricity by more than 1.5 ten thousand yuan for one pump per year, thereby saving the production cost for users.
The pump shaft is short, vibration of the pump is reduced, the service life of a motor bearing is long, and the number of maintenance assembly parts is small.
The pump body structure adopts a single-stage liquid-guiding filling principle to conduct one-time drainage, vacuum time is not needed, the self-suction effect is good, liquid can be discharged when a power supply is started (0 self-suction time), and the energy-saving effect is achieved.
The sealing adopts a built-in negative pressure structure, has no leakage during operation, does not bear the pressure of a pump, and has the service life longer than that of a common mechanical seal by more than 10 times. The mechanical seal is a Bogman built-in seal 109.
