Untimely replenishing can constantly consume at pump oil in running, if will cause in the pump pressure unbalance and make the pump cisco unity malfunction.The High Temperature High Pressure reciprocating oil isolation membrane pump fluid end often adopts the constant repairing both at home and abroad at present.When repairing amount during less than requirement, slurries can cause the wearing and tearing of fluid end, and during serious wear, pump is with cisco unity malfunction; When repairing amount during greater than requirement, the oil that has more will improve operating cost with carrying liquid drain.
Summary of the invention
The object of the present invention is to provide a kind of oil balancing system, to satisfy the normal use of the reciprocating oil isolation membrane pump of carrying the High Temperature High Pressure slurry.
The objective of the invention is to be achieved through the following technical solutions: a kind of oil balancing system of reciprocating oil isolation membrane pump fluid end, comprise cylinder body, barrier film, be positioned at the bleed valve of cylinder body upper end and be positioned at the Fill valve of cylinder body lower end, oily isolation tank, it is characterized in that: adopt oily isolation diaphragm type structure, blow-off system and oil-supplementing system acting in conjunction, the oil level in the control isolation tank moves in safety range.
Oil isolation diaphragm type structure adopts oily isolation tank to connect cylinder body and flow passage components, and the isolation tank middle and upper part is an oil, and its underpart is the high temperature slurry, so just barrier film and slurry are kept apart with oil, the heat transfer property of oil is relatively poor, has reduced the operating temperature of barrier film, the working life of having improved barrier film.
Blow-off system is a bleed valve, and bleed valve is made up of the opposite one-way valve of both direction.
Oil-supplementing system is an electric control system, Fill valve links to each other with slippage pump by pipeline, communicate with system oil-way simultaneously, the high-low limit position of oil level is established the contact respectively in oily isolation tank, electric control signal is sent in the contact, the control slippage pump begins or stops repairing, and oil level is moved between the high-low limit position.
Bleed valve is positioned at the cylinder body top, can be considered two one-way valves, first one-way valve opens under the normal state, second one-way valve closure.Gas in the pump in the residual empty G﹠O can overflow and accumulate in the cylinder body top gradually in the pump operation process, gather to a certain degree and produce certain pressure, make first closed check valve, simultaneously a small amount of gas overflows, second one-way valve opens, gas release is gone out, and can take away a small amount of oil simultaneously.Fill valve is positioned at the cylinder body lower end, can be considered an one-way valve, communicates by pipeline with slippage pump, and is closed under the normal state, when slippage pump begins repairing, and one-way valve opens.
In the pump work process, oil is constantly discharged along with slurry, a spot of oil of taking away when adding the bleed valve venting, and the oil in the active chamber constantly reduces, and the oil level in the oily isolation tank constantly rises.When rising to certain altitude, slurry flows into cylinder body and causes wearing and tearing.During the slippage pump repairing, oil level descends gradually in the oily isolation tank, drops to certain altitude, and oil enters the loss that the flow passage components runner causes oil.Therefore, must be within the specific limits with oil level control.The high-low limit position of oil level is established upper contact and lower contact respectively in oily isolation tank.When the oil level in the oily isolation tank arrives upper contact, send electric control signal, make the automatic repairing of slippage pump; When the oil level in the oily isolation tank drops to lower contact, send electric control signal, slippage pump stops repairing.Through the continuous circulation of above-mentioned working state, promptly reach the oily balance of fluid end system.
Blow-off system of the present invention is to carry out at the pump work state, and oil-supplementing system carries out under the pump off working state, promptly carries out repairing when the plunger backhaul, and the phase difference of slippage pump and pump is 180 °.
The invention has the beneficial effects as follows: be quick on the draw, can control oil level in the isolation tank during slippage pump repairing effectively in safety range, prevent that oil level is too high or too low and cause the pump can't proper functioning, reduced the operating temperature of barrier film, the working life of having improved barrier film.
