Abstract

The utility model discloses a pump, which comprises a diaphragm chamber and an inlet valve chamber and is characterized in that the valve chamber outlet of the inlet valve chamber is connected to the diaphragm chamber through a 90-degree elbow, so that the diaphragm chamber and the inlet valve chamber are not mounted on the same perpendicular line and are horizontally connected. Since four screws for fixing the end cover of the inlet valve chamber are perpendicularly mounted through the pump, and the screws only sustain the acting force in the same direction instead of the acting force in different directions, the fracture problem of the screws is solved, and the huge potential safety hazard that the slurry is sprayed out due to the screw fracture is further eliminated.

Description

A kind of pump

Technical field

The utility model belongs to oar body line transportation field, particularly relates to a kind of pump.

Background technique

In the conveying of present slurry pipeline, employed pressurized equipment is TZPM 1600 main pumps, the mounting type of the inlet valve room cover plate of this main pump is for being installed on the side of inlet valve chamber along the direction level that moves horizontally, as shown in Figure 1, end cap 5 and fixedly the screw rod 6 of end cap be installed in valve chamber 1 front, also be to be level to install, such mounting type has directly caused screw rod 6 bearing two different power in the horizontal and vertical directions, be that main pump is in the middle of the process of operation, screw rod is bearing when being advanced by piston forward, when the substantially horizontal that is passed over to end cap 5 by slurry in the storehouse in the valve chamber 3 is higher than the pressure of 200KG, also to bear 5 pressure of an end cap in Vertical direction.Because two different pressure are not in same direction, but form 90 ° angle, under the effect of these two power, final result is, descend the working life of four screw rods 6 greatly, the situation of fracture often occurs, and in screw rod 6 fractures, slurry in the valve chamber in the storehouse 3 can be spouting, forms huge potential safety hazard.

The model utility content

The purpose of this utility model is to have designed a kind of TZPM 1600 pumps, and its special mounting structure can solve the problem and the spouting situation of screw rod fracture back slurry of cover plate screws fracture.

The utility model discloses a kind of pump, comprise chamber of septum and inlet valve chamber, it is characterized in that: the outlet of the valve chamber of described inlet valve chamber is connected to described chamber of septum by one 90 ° of bend pipes, makes the installation of described chamber of septum and described inlet valve chamber not on a vertical line, and horizontally connects.

Further, the slurry outlet of inlet valve chamber is arranged on the back of inlet valve chamber.

Further, also comprise end cap, vertically be installed in the top of inlet valve chamber, the screw rod of fixing described end cap also vertically is installed on the end cap.

The utility model compared with prior art has following beneficial effect:

(1) because the utility model makes four screw rods of fixing inlet valve chamber end cap form vertical mounting type, no longer be subjected to the effect of the power on the different direction on stressed, promptly screw rod only bears the active force of same direction, can solve the problem of screw rod fracture.

(2) because the utility model has solved the problem of screw rod fracture, the also huge potential safety hazard that the slurry that causes ejects because screw rod ruptures with regard to having eliminated.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 2, valve chamber outlet 4 is arranged at valve chamber 1 side, valve chamber outlet 4 is connected with the inlet of chamber of septum 8 by one 90 ° of bend pipes 7, thereby make chamber of septum 8 and being connected of valve chamber outlet 4 convert the angle connection that forms 90 ° to by the connection that is vertically on the same line, so just can make end cap 5 can be vertically mounted on valve chamber 1 top along the mode that Vertical direction moves, thereby making fixedly, the screw rod 6 of end cap has also just formed vertical mounting type, other parts in the slurry in storehouse 3 inlet 2 and the valve chamber thereof do not need to make any change in the valve chamber like this, only the slurry outlet 4 of valve chamber need be changed to get final product in the side of valve chamber 1.In the middle of the process of main pump operation, the slurry pressure in the valve chamber in the storehouse 3 is delivered on the screw rod 6 by rubbing surface of end cover 11, end cap 5 like this.Because end cap 5 has been vertical mounting type, so the pressure direction of end cap that slurry passes to is vertically upward, thereby make the stressed direction that also is straight up of screw rod 6, the installation direction that is subjected to force direction and screw rod of screw rod is on same vertical line, simultaneously, because the mounting type of end cap 5 vertically is installed on directly over the inlet valve chamber 1, so the pressure that end cap gravity is produced just directly acts on the inlet valve chamber 1, and do not act on the screw rod 6, be the effect that 6 of screw rods bear a pressure consistent with its installation direction, so just solved the problem of screw rod fracture.

Claims (3)

1. pump, comprise chamber of septum (8) and inlet valve chamber (1), it is characterized in that: the valve chamber outlet (4) of described inlet valve chamber (1) is connected to described chamber of septum (8) by one 90 ° of bend pipes (7), makes described chamber of septum (8) and described inlet valve chamber (1) horizontally connect.

2. pump according to claim 1 is characterized in that: the slurry outlet (4) of inlet valve chamber (1) is arranged on the back of inlet valve chamber (1).
