Description

Pump oil supply system
Technical field
The utility model belongs to pump technology field, relates to a kind of pump oil supply system, particularly a kind of oil-filled type submersible pump oil supply system.
Background technique
Present oil-filled type submersible pump is used more and more, and using scope is also more and more wider, and its safety and reliability receives much concern.Oil-filled type submersible pump operationally, causes inner oily expanding volume to increase because motor is heated, the machine barrel if the oil added too completely can rise brokenly; motor is exploded; if the oil added is discontented can affect Cooling and Lubricator again, therefore, need in submersible pump, increase a kind of safety protection device.Safe leather sac is a kind of very important safety protection device; be contained in pump and the oil in pump not only can be made to fill it up with; play the effect of abundant Cooling and Lubricator; but also the pressure that a certain amount of oil plays ballast pump inside and outside can be added; thus it is equal with pressure outside pump to make in pump, significantly reduces obturator because of outer force unbalance and cause the damage that causes.
Existing safe leather sac and machine barrel are for seal tight fit connection, need to bear larger pressure, this just causes refueling inconvenience, when needing to refuel, is pulled down by safe leather sac, again safe leather sac is loaded after injecting oil, the oil injected has certain pressure, and safe leather sac is not easily installed, and operation is wasted time and energy, there will be oil during installation to ooze out, oil filling amount cannot be determined.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of oiling pump oil supply system easily.
The purpose of this utility model realizes by following technical proposal:
This pump oil supply system, comprise the shoe cream room being located at oil-filled type submersible pump top and the elasticity leather bag for closed shoe cream room being located at shoe cream room opening, described elasticity leather bag has the leather bag base being positioned at shoe cream room, the opening of described shoe cream room is provided with fixed cover, spring is provided with between described fixed cover and leather bag base, it is characterized in that, the lower side of described shoe cream room is provided with the oil inlet pipe be communicated with shoe cream room, described oil inlet pipe is provided with valve one, the upper lateral part of described shoe cream room is provided with the return tube be communicated with shoe cream room, described return tube is provided with valve two.
When oil expands, spring-compressed makes elasticity leather bag shrink, and under the action of the spring, elasticity leather bag is in retracted position, makes motor be in full oil condition all the time, ensures lubrication and cooling, effectively extends the working life of motor.
In above-mentioned pump oil supply system, be equipped with pull bar in described fixed cover, the inner and the leather bag base of described pull bar are connected.During toward shoe cream room oiling, pull bar is pulled upwardly, makes the capacity of shoe cream room be in maximum rating, open the valve two on return tube and the valve one on oil inlet pipe, oil enters in shoe cream room from oil inlet pipe, when there being oil to flow out in return tube, illustrating in shoe cream room and filling oil, first close the valve two on return tube, close the valve one on return tube again, releasing lever, oiling is convenient, there will not be leakage phenomenon.
In above-mentioned pump oil supply system, the opening of described shoe cream room has annular stop step, described elasticity leather bag has the annular arranged that to match with this annular stop step and keep off edge, under the effect of above-mentioned fixed cover, annular gear is along being resisted against on described annular stop step.
In above-mentioned pump oil supply system, the opening of described shoe cream room is also provided with the anti-decylization for preventing fixed cover from coming off, above-mentioned annular gear along respectively with annular stop step and fixed cover drive fit.
In above-mentioned pump oil supply system, described leather bag base is provided with fixed base.
Compared with prior art, this pump oil supply system has the following advantages:
Its reasonable in design, when oil expands, elasticity leather bag shrinks, and motor can not be blasted, and Security is high; Under the action of the spring, elasticity leather bag is in retracted position, makes motor be in full oil condition all the time, ensures lubrication and cooling, effectively extends the working life of motor; Be sidelong increase oil inlet pipe and return tube, convenient toward oiling in shoe cream room.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment that the utility model provides.
In figure, 1, shoe cream room; 11, annular stop step; 12, anti-decylization; 2, elasticity leather bag; 21, leather bag base; 22, annular gear edge; 23, fixed base; 3, fixed cover; 4, spring; 5, oil inlet pipe; 6, return tube; 71, valve one; 72, valve two; 8, pull bar.
