Abstract
The utility model relates to a pump special for a leakage-free press filter, which is composed of a pump body, a pump cover, a pump shaft, a mechanical seal section, etc. The utility model is characterized in that an outlet end is positioned on the front upper part of the pump body, an inlet end is positioned on any angles of the rear direction of the pump body, and the mechanical seal section is arranged in the inner side of the inlet end. When the pump is in the process of working, owing to the function of impeller wheels, the mechanical seal section is in a negative pressure state, and thus, a press cover sealed by a machine has no need to tightly press, the abrasion of the mechanical seal section can be reduced, the mechanical seal section has no any working pressure for long time operation, and the utility model not only can solve the seal leakage problem of a pump but also can increase the service life of a pump.
Description
The utility model relates to a kind of Leakless pressure filter dedicated pump.
At present, delivery temperature is that-10 ℃～110 ℃ various corrosion liquid slurries that have particle, viscosity adopt general enamel linedpump, ceramicpump, rubber lined pump, fluorine alloy pump, F type corrosion-resistant pump and chemical centrifugal pump etc. mostly in the pressure filter technological process.Defectives such as these pumps constantly increase and long-term delivery liquid under the situation that flow reduces gradually at pressure, and the working pressure that mechanical seal is born constantly increases, and leakage phenomenon occurs through regular meeting, and working life is short.
The purpose of this utility model just provides a kind of Leakless pressure filter dedicated pump, working pressure is not born in mechanical seal; guarantee that mechanical seal never leaks, can satisfy that delivery temperature is the various corrosion liquid slurries of-10 ℃～110 ℃ band particles, viscosity in the pressure filter technological process.
The purpose of this utility model is to realize like this, Leakless pressure filter dedicated pump is by impeller, the pump housing, pump cover, pump shaft and mechanical seal etc. are partly formed, it is characterized in that: this pump discharge port is in its front upper place, material feeding mouth is arbitrarily angled its rear, this pump mechanical sealing spare adopts negative pressure device, mechanical seal is installed in the inside line of entrance point, because the pump housing is in operation process, entrance point forms negative pressure, make mechanical seal be in negative pressure state always, any working pressure is not born in so long-time running mechanical seal, mechanical seal simultaneously need not to press too tightly, reduce the wearing and tearing of mechanical seal, not only solved the seal leakage problem of general pump, and the working life of having improved the pump housing.
The utility model compared with prior art has following advantage:
1, mechanical seal is in negative pressure state, leakage phenomenon can not occur.
2, the mechanical seal wearing and tearing reduce the working life of having improved pump.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 does not have the structural representation that leaks the pressure filter dedicated pump for the utility model
Fig. 2 is the structural representation of the mechanical seal of Leakless pressure filter dedicated pump shown in Figure 1
1, only starches fragrant plant sheet 2, spacer 3, impeller nut 4, impeller 5, pump door 6, the pump housing 7, pump cover 8, mechanical seal 9, pump bracket 10, pump shaft 11, bearing 12, bearing gland 13, axle sleeve 14, machine sealed cover
As can be seen from Figure 1 (the utility model entrance point draws by half-twist), Leakless pressure filter dedicated pump is made up of parts such as the pump housing 6, pump cover 7 pump shafts 10, impellers 4, and pump cover 7 is pressed on the pump bracket 9 by the pump housing 6.Pump shaft 10 is installed on the pump bracket 9 by bearing 11 and bearing gland 12, and impeller 4 is fixed on the front end of pump shaft 10 by impeller nut 3.As can be seen from Figure 2, axle sleeve 13 is housed on the pump shaft 10, mechanical seal 8 is housed between pump cover 7 and axle sleeve 13 and is pressed on the pump cover 7 by machine sealed cover 14, pump cover 7 front ends are equipped with only to be starched fragrant plant sheet 1 and prevents that the slip particle of carrying from entering.It is characterized in that: this mechanical seal 8 is installed in entrance point A inside line, in the pump work process, because outlet end B is in the front upper place, inlet part is owing to the effect of impeller 4 is in negative pressure state, be that any working pressure is not born in mechanical seal 8, this model machine sealed cover 14 need not to press too tightly, can reduce the wearing and tearing of mechanical seal 8, not only improve the working life of pump, and solved the seal leakage problem of general pump.
