Description

There is the two-way pump of external motors

Technical field

The present invention relates to a kind of two-way pump with external motors, it is applicable to the fluid delivery device needing bidirectional fluid to transmit, such as preventing the anti-dumping side system of boats and ships canting or shake.

Background technology

Usually, in order to prevent boats and ships canting or shake because of wave, be provided for the anti-dumping side system automatically keeping balance.

Fig. 1 is the plan view from above of conventional anti-dumping side system 400.

In this case, ballast pump P1 and P2 of engine room is one-way pump, therefore, they are connected independently by the pipe separated in engine room E1, and should pipe separately by multiple valve V1, V2, V3 ... medium be connected to the pipe be connected with the left case 1200A of the center being arranged in boats and ships and right case 1100A.

When the ballast water of left case 1200A is transferred to right case 1100A by the anti-dumping side system 400 of such routine, multiple valve V1, V2, V3 ... the pipe installed for pump P1 is connected with the pipe being connected to left case 1200A and right case 1100A, ballast water is transferred to right case 1100A from left case 1200A.On the contrary, when the ballast water of right case 1100A is transferred to left case 1200A, multiple valve V1, V2, V3 ... the pipe installed for pump P2 is connected with the pipe being connected to left case 1200A and right case 1100A, ballast water is transferred to left case 1200A from right case 1100A, make anti-dumping side system can perform anti-canting function.

Therefore, the anti-dumping side system 400 with the routine of one-way pump has such shortcoming, that is, system architecture is complicated and because a large amount of valve and long tube are so need to spend the much time to have an effect.In order to overcome the shortcoming of conventional anti-dumping side system, this anti-dumping side system comprises installation two-way pump between the tubes, and described pipe is connected directly to the anti-canting case on left side and the right side being arranged on boats and ships so that maintenance balances and simplifies the structure of system rapidly.

For this reason, the two-way pump P1 with external motors is configured to bidirectional transmission fluid.Fig. 2 illustrates the section-drawing with the two-way pump P ' of the routine of external motors for bidirectional transmission fluid.

Electricity gear 2120 and driven gear 2130 change their hand of rotation according to the hand of rotation of CD-ROM drive motor 2240, make pump P ' can optionally bidirectional transmission fluid.

But conventional pump P ' has Railway Project: because the stream of the main shaft 2140 of finishing bevel gear cuter 2230 and fluid is not in the same direction, therefore pump can cause degradation of energy, and therefore, pump causes the efficiency of pump performance to decline.

And conventional pump P ' has another problem: pump performance can due to finishing bevel gear cuter 2230 overheated, leaks from the oil of sealing member, the decline of the speed of the fluid of Bottomhole pressure that causes because of the closure member installed for finishing bevel gear cuter and deterioration in efficiency.
