Abstract

A concrete transfer pump employing the double oil pump comprises a transfer pump set (6), characterized in that the utility model is equipped with two oil pumps (1,2), wherein the hydraulic oil output end of one oil pump (2) is connected with the hydraulic oil output end of the other oil pump (1) through a one-way valve (3). The utility model can satisfy the long-distance and high transfer-resistance concrete pumping, and provide high oil quantity which can satisfy the long-distance and high-pressure concrete pumping. The pressure of the transfer pump outlet can reach to 20Mpa, and the utility model has low operating cost, energy saving, convenient utilizing and reliable system.

Description

Adopt the concrete pump of two oil pumps

Technical field

The utility model belongs to concrete pump.

Background technique

At present, concrete pump adopts oil pump systems mostly to be single oil pump systems or two-in-series main oil pump system.Single oil pump systems is limited by the oil pump maximum pump discharge, has the not enough situation of output oil mass, and the maximum pump discharge of BOSCH-REXROTH oil pump list pump is 260 at present, and there is power source power match situation of difficult again in the pumps in series system, and the cost that increases on power source is too high.

The model utility content

The technical problems to be solved in the utility model is, at the deficiencies in the prior art, design a kind of concrete pump that adopts two oil pumps, have for system provides the oil mass height, can satisfy remote, high pressure concrete pumping, low, energy-conservation and easy to use, the system's reliable characteristics of operating cost.

The technical solution of the utility model is, the concrete pump of the two oil pumps of described employing has the transfer pump complete machine, its structural feature is, it is provided with two table oil pumps, and wherein the high pressure oil output terminal of a table oil pump joins through the high pressure oil output terminal of an one-way valve and another table oil pump.

Below the utility model made further specify.

As shown in Figure 1, the utility model has transfer pump complete machine 6, and its structural feature is, it is provided with two

table oil pumps

1,2, and wherein the high pressure oil output terminal of a table oil pump 2 joins through the high pressure oil output terminal of an one-way valve 3 with another table oil pump 1.

Said structure can make hydraulic oil from the high voltage terminal of the oil pump 2 high pressure oil interflow of one-way valve 3 and oil pump 1 of flowing through, thereby can obtain the driving hydraulic oil of high pressure, big flow.Two

table oil pumps

1,2 can be made as main oil pump and auxiliary oil pump respectively, major and minor oil pump provides power (referring to Fig. 2, Fig. 3) by different power sources, and main oil pump can work independently, and when the high-power demand of needs, double pump is worked simultaneously, and hydraulic power is abundant; When little discharge capacity can satisfy construction requirement, the main oil pump system worked independently, energy saving.

As known from the above, the utility model is for adopting the concrete pump of two oil pumps, can satisfy the concrete pumping of long distance, high transporting resistance, the advantage of this equipment has: (1) system provides the oil mass height, (2) can satisfy remote, high pressure concrete pumping, (3) the transfer pump outlet pressure can reach 20Mpa, and (4) operating cost is low, energy-conservation, and (5) are easy to use, system is reliable.

Description of drawings

Fig. 1 is a kind of embodiment's catenation principle figure of two oil pumps;

Fig. 2 is a kind of embodiment's a complete machine structure schematic representation;

Fig. 3 is the plan structure schematic representation of device shown in Figure 2.

In the drawings:

1,2-oil pump, the 3-one-way valve, 4, the 5-motor,

Embodiment

As shown in Figures 1 to 3, the utility model is provided with two

table oil pumps

1,2 for dragging pump, and wherein the high pressure oil output terminal of a table oil pump (being made as auxiliary oil pump) 2 joins through the high pressure oil output terminal of an one-way valve 3 with another table oil pump (being made as main oil pump) 1.Two

table oil pumps

1,2 adopt (commercially available) BOSCH-REXROTH A11V (L) 0190+A10V028+1PF2GZ-4X/022 and A11V (L) 0190 or A11V (L) 260 and A11V (L) 0190, form separate double oil pump concrete pump, it is particularly useful for high-speed railway system beam concrete conveying equipment.

Claims

1, a kind of concrete pump that adopts two oil pumps, comprise transfer pump complete machine (6), it is characterized in that it is provided with two table oil pumps (1,2), wherein the high pressure oil output terminal of a table oil pump (2) joins through the high pressure oil output terminal of an one-way valve (3) with another table oil pump (1).
