Abstract
The invention relates to a core sampler with controlled cooling water. The core sampler is an apparatus for drilling a core sample, and belongs to the technical field of a petroleum geology apparatus. The core sampler with controlled cooling water controls the on-off of a water seal cooling system through arranging a normally-closed electric water valve and controls the operation of a sampling motor and the normally-closed electric water valve through arranging an alternating current contactor controlled by a button switch. Once the operation state of the sampling motor is controlled, the operation state of the normally-closed electric water valve can be controlled at the same time so as to switch on and switch off a cooling water source of the water seal cooling system and completely overcome the phenomena that the cooling water of the core sampler transversely flows on the operation spot. The invention is beneficial to improving the operation environment with convenient operation and reducing the development cost of petroleum geology exploration, saves a large amount of water resources at the same time, and has simple structure, strong practicability, obvious energy-saving and emission reduction and economic effect.
Description
Technical field
The present invention relates to the controlled core sampler of a kind of cooling water, core sampler is the instrument that drills through core sample, belongs to the petroleum geology Instrument technology field.
Background technology
In the petroleum geology exploration exploitation, need formation parameter is done various experiment test work.In order to finish these experiments, at first need on rock core, to drill through the sample of all size with core sampler.
The present core sampler of using, at the drill bit periphery parcel water seal cooling system that the sampling motor connects, the water seal cooling system directly connects cooling water source through pipeline, because the water seal cooling system is not provided with the mechanism of the opening and closing of control cooling water, thereby no matter be dress sample, following sample, still adjust, cooling water is all being opened in entire work process, working site cooling water crossing current, especially in severe winter, the working site environment is abominable, not only brings the inconvenience of work to operating personnel, has also wasted great lot of water resources.
Summary of the invention
The objective of the invention is at existing core sampler water seal cooling system because of the opening and closing mechanism of control cooling water is not set, there is the inconvenience that not only brings work to operating personnel, also wasted the deficiency of great lot of water resources, provide a kind of cooling water controlled core sampler, only when the sampling machine operation, just connect cooling water, not only help improving working environment, handled easily, also can save great lot of water resources.
The objective of the invention is to be achieved through the following technical solutions, the core sampler that a kind of cooling water is controlled, comprise the water seal cooling system of the peripheral parcel of drill bit that is connected with the sampling motor and the cooling water source that the water seal cooling system connects through pipeline, it is characterized in that, be connected in series normally closed dynamoelectric water valve in the connecting pipe of water seal cooling system and cooling water source, the A.C. contactor that press button control is set connects the power end of normally closed dynamoelectric water valve, sampling motor respectively.
The present invention is by being provided with the unlatching and the shutoff of normally closed dynamoelectric water valve control water seal cooling system, control the work of sampling motor and normally closed dynamoelectric water valve by the A.C. contactor that press button control is set, as long as the duty of control sampling motor, can control the duty of normally closed dynamoelectric water valve simultaneously, thereby realize opening and turn-offing the cooling water source of water seal cooling system, overcome the phenomenon of existing core sampler working site cooling water crossing current fully, not only help improving working environment, handled easily, saved great lot of water resources simultaneously, help reducing the petroleum geology exploration development cost, the present invention is simple in structure, practical, have considerable energy saving emission reduction effect and economic benefit.
Description of drawings
Fig. 1 is an electric connecting relation schematic diagram of the present invention;
The specific embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the present invention is made of sampling motor, press button, A.C. contactor, water seal cooling system and normally closed dynamoelectric water valve, normally closed dynamoelectric water valve is serially connected in the connecting pipe of cooling water source and water seal cooling system, the A.C. contactor of press button control connects the power end of normally closed dynamoelectric water valve, sampling motor respectively, if A.C. contactor is not connected, the sampling motor is not worked, normally closed solenoid valve is in closure state, cooling water (tap water) is obstructed, can go up work such as sample, adjustment easily.When pressing the button " the opening " in the switch, A.C. contactor is connected, the sampling machine operation, and normally closed dynamoelectric water valve is in opening, and cooling water enters the water seal cooling system, the work of taking a sample normally.After a sample is got, press the button " pass " in the switch, A.C. contactor disconnects, and the sampling motor quits work, and normally closed dynamoelectric water valve is in closed condition, and cooling water disconnects, and can play sample easily, go up work such as sample, adjustment.So move in circles, promptly made things convenient for operation, saved water resource again.
Press button among the present invention, A.C. contactor and normally closed dynamoelectric water valve all can adopt existing product.
