Abstract

The utility model provides an improved hydraulic station, which comprises a console cabinet body, an oil tank, proportional reversing valves, a motor, a plunger pump, an oil suction filter, manifold blocks and a directional control valve, wherein the oil tank, the proportional reversing valves, the motor, the plunger pump and the oil suction filter are positioned on the console cabinet body; the motor is connected with the plunger pump; the oil suction filter is arranged on the plunger pump; the proportional reversing valves are connected to the motor; the manifold blocks are arranged on the console cabinet body; and the directional control valve is connected in series with the proportional reversing valves. The utility model has the advantages that: the hydraulic station can control a plurality of pieces of equipment, and has the advantages of simple structure, resource saving, low machining cost and the like; and in addition, the designs of oil passing grooves in the manifold blocks are changed, and then oil pipes can be connected with the oil passing grooves without bending, so that not only the condition of oil leakage is avoided, and but also pressure loss caused by the bending of the oil pipes is avoided.

Description

A kind of improved hydraulic station

Technical field

The utility model relates to a kind of hydraulic station, especially relates to a kind of hydraulic station of mining hydraulic disassembling and assembling machine.

Background technique

Hydraulic disassembling and assembling machine is widely used on the oil drilling platform.All need hydraulic station that power is provided when oil drilling tools disassembly-and-assembly machine in existing technology and the work of bumper jar Laboratory Furniture.Cause on a hydraulic disassembling and assembling machine, existing the situation of a plurality of hydraulic stations; The adding up of using effect of repeating resource on many hydraulic disassembling and assembling machines like this will be caused the serious wasting of resources.How solving through many external equipments of a hydraulic station control is problems that the utility model will solve.

In addition, most hydraulic stations were realized with being connected through the transition tube pipeline connector of external device.Under this Placement, the operation of screwing of a plurality of transition tube pipeline connectors makes baffle plate generation deformation.Because baffle plate is the piece thin plate, after the generation deformation.The transition tube pipeline connector produces the leakage of oil point with crossing being threaded between the oil groove, causes the hydraulic system leakage of oil.Simultaneously, there is bending in oil pipe, causes hydraulic oil to have the pressure loss, and making oily temperature rise directly influences the work of hydraulic system.The harm of oil temperature rise:

The warm too high meeting of oil causes the hydraulic pressure oil viscosity to descend, and is easy to generate leakage, and volumetric efficiency is reduced;

The part of hydraulic system expands because of overheated; Owing to the linear expansion coefficient of each constituent element of system, be heated and radiating condition is not quite similar; Each several part expanded by heating situation is also not exclusively the same, thereby the distortion that produces is also different, may destroy the original normal matching gap of part of relative movement; Cause surface friction drag to increase, it is stuck that spool is prone to;

Also possibly destroy the oxidation stability and the thermostability of fluid;

Quicken the Sealing aged deterioration, the lost of life, the loss of seal performance is seriously leaked system; The oil temperature is too high, is easy to generate impurity etc.

Summary of the invention

The problem that the utility model will solve provides a kind of improved hydraulic station, has solved the problem by hydraulic station control multiple devices, has practiced thrift resource, has reduced cost of production; Effectively connect hydraulic station and external device; Have the characteristics of anti-leakage of oil, avoided the pressure loss; Especially be fit to hydraulic disassembling and assembling machine on the oil drilling platform.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of improved hydraulic station comprises operating console casing and position fuel tank, proportional reversing valve, motor, plunger pump and oil suction filter cleaner on it; Also comprise manifold block and position control valve; Motor is connected with plunger pump, and the oil suction filter cleaner is installed on the plunger pump, and proportional reversing valve is connected on the motor; On the operating console casing manifold block is installed; Position control valve is serially connected on the proportional reversing valve.

Further, said manifold block is provided with the oil groove of crossing that parallels; Cross the oil groove two ends and have screw thread.

Preferably, the shape of crossing oil groove of said manifold block is a right angle type.

Further, at position control valve of the A of proportional reversing valve mouth series connection.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; At position control valve of the A of proportional reversing valve mouth series connection, realize having simple in structure by hydraulic station control multiple devices; Resources conservation, advantage such as processing cost is low.Simultaneously, changed the design of oil groove excessively in the manifold block, oil pipe need not bending again and just can be connected with the mistake oil clot; Neither can produce the situation of leakage of oil, avoid again because the pressure loss that the oil pipe bending causes.

Embodiment

Shown in Fig. 1 to 5, the utility model provides a kind of improved hydraulic station, comprises operating console casing 8 and position fuel tank 1, proportional reversing valve 2, motor 3, plunger pump 6 and oil suction filter cleaner 7 on it; Also comprise manifold block 4 and position control valve 5; Motor 3 is connected with plunger pump 6, and oil suction filter cleaner 7 is installed on the plunger pump 6, and proportional reversing valve 2 is connected on the motor 3; Manifold block 4 is installed on the operating console casing 8; Position control valve 5 is serially connected on the proportional reversing valve 2.

Said manifold block 4 is provided with the oil groove 9 excessively that parallels; Cross oil groove 9 two ends and have screw thread.

Another kind of preferred version is that the shape of crossing oil groove 9 of said manifold block 4 is right angle types.

At position control valve 5 of the A of proportional reversing valve 2 mouth series connection.

The working procedure of this instance: motor 3 provides power for plunger pump 6, and plunger pump 6 work drive oil suction filter cleaners 7 fluid in the fuel tank 1 is pumped into, and deliver to proportional reversing valve 2 again.Position control valve 5 is serially connected on the proportional reversing valve 2, and hydraulic oil is controlled two equipment works simultaneously through direction control valve 5; Some hydraulic oil is sent to hydraulic station through manifold block 4, is the external device fuel feeding.
