Abstract
The utility model relates to a two-way slave plunger grease lubricating pump, which comprises a left and a right pump chambers, a left and a right pistons which are connected by a core shaft, a left power and a right power oil inlets and outlets for alternately filling oil, and lubricant grease in-out oil channels. The utility model can timely alternate and force the piston of a lubrication concrete cylinder, etc.; thus, the service life of the lubrication part can be prolonged, the grease can be saved, and the lubricating efficiency can be improved.
Description
Building machinery relates to the two-way servo-actuated plunger type grease lubrication pump that the mechanical lubrication of concrete pump class is used.
Construction industry wants frequent fatten lubricated with the concrete cylinder piston and the similar devices thereof of concrete pump machines, and three kinds of lubricating systems are arranged at present, adopts Hydraulic Power Transmission System pressure fuel tap, and the hydraulic pressure loss is arranged; Water between employing master hydraulic cylinder and the concrete cylinder in the water tank is made oiling agent, the concrete cylinder piston wear is big, the single plunger grease lubrication pump that adopts double acting cylinder to drive, because the lubricated of two concrete cylinder pistons must hocket, and only when realizing pumping, pressure oil just realizes corresponding coagulation cylinder piston is applied lubricating grease, this structure can only be to a piston lubrication, another piston is when pumping lubricating grease, all the time not on its corresponding position, lubricating grease can only be sprayed on the cylinder barrel, thereby lubrication effect is bad.
The purpose of this utility model is the fuel-efficient again alternately lubricated lubricant pump of timing fixed point of a kind of lubricating efficiency height of design.
The two-way servo-actuated plunger type lubricant pump of the utility model design includes the pump housing, piston, mandrel, pump cover, valve etc., it is characterized in that the pump housing ［ 3 ］ includes chamber ［ 20 ］, a pump left side, the right chamber ［ 15 ］ of pump, plunger type left piston ［ 6 ］ and right piston ［ 17 ］ by mandrel ［ 7 ］ connection, pump left side chamber lubricating grease oil input channel ［ 2 ］ and the right chamber lubricating grease oil input channel ［ 18 ］ of pump are arranged at pump chamber top, the left and right sides, the bottom is connected to pressure grease left side outlet ［ 8 ］ and the pressure grease right side exports ［ 14 ］ also respectively, be connected with left one-way valve ［ 9 ］, right one-way valve ［ 13 ］ and relief valve ［ 10 ］, the pump housing ［ 3 ］ side have left power oil import and export ［ 5 ］ and the right power oil import and export ［ 16 ］ of alternately changing oil-feed by selector valve.Can connect in the pump chamber, a left side of two-way servo-actuated plunger type grease lubrication pump and the right chamber of pump also can be in parallel.
The two-way servo-actuated plunger type grease profit pump of the utility model design is fixed in the lubricating grease fuel tank, and its filler opening communicates with fuel-tank outlet, and the one-way valve outlet is connected to the position that need lubricate, and power oil is imported and exported with the corresponding selector valve of host hydraulic system and connected.
The two-way servo-actuated plunger type grease lubrication pump that employing the utility model proposes can make the concrete cylinder piston obtain regularly fixed point exchange and lubricate, and improves piston seal, and the reliability of the life-span of cylinder body and concrete pump machine can also be saved lubricating grease.
Fig. 1 is a kind of structural representation of the two-way servo-actuated plunger type grease lubrication pump that the utility model proposes.
Fig. 2 is a kind of parallel-connection structure schematic representation of two-way servo-actuated plunger type grease lubrication pump.
The pump housing ［ 3 ］ of the two-way servo-actuated plunger type grease lubrication pump among Fig. 1 places the below of lubricating grease fuel tank ［ 1 ］, lubricating grease is by pump left side chamber lubricating grease oil input channel ［ 2 ］, the right chamber lubricating grease oil input channel ［ 18 ］ of pump, enter the right chamber ［ 15 ］ of pump chamber ［ 20 ］, a left side and pump, left piston ［ 6 ］ and right piston ［ 17 ］ that the centre has mandrel ［ 7 ］ to connect, the bottom is pressure grease left side outlet ［ 8 ］ and the right outlet of pressure grease ［ 14 ］, be connected to left one-way valve ［ 9 ］ below respectively, right one-way valve ［ 13 ］, and relief valve ［ 10 ］, relief valve drain pipeline ［ 14 ］ and pressure grease output tube ［ 12 ］.Import and export ［ 16 ］ when power oil from right power oil and enter the pump housing, promote right piston ［ 17 ］, by mandrel ［ 7 ］ left piston ［ 6 ］ is moved to the left, lubricating grease in the right chamber of pump ［ 15 ］ is extruded by the right outlet of pressure grease ［ 14 ］, one-way valve ［ 13 ］ enters pressure grease output tube ［ 12 ］, to respectively needing the lubricant housings.Meanwhile, because left piston ［ 6 ］ moves to left, make pump chamber, a left side ［ 20 ］ form vacuum, lubricating grease in the lubricating grease fuel tank ［ 1 ］ be inhaled into chamber ［ 20 ］, a pump left side under the barometric pressure effect by pump left side chamber lubricating grease oil input channel ［ 2 ］, after the power oil commutation, pressure oil is imported and exported ［ 5 ］ from left power oil and is entered the pump housing, effect is with last similar, by pressure grease left side outlet ［ 8 ］, one-way valve ［ 9 ］ enters pressure grease output tube ［ 12 ］ to respectively needing the lubricant housings simultaneously with the lubricating grease in the pump chamber, a left side ［ 20 ］.The right chamber of pump ［ 15 ］ sucks lubricating grease.When the lubricating grease pressure in the pipeline ［ 12 ］ surpasses relief valve ［ 10 ］ setting pressure,, flow back to the lubricating grease fuel tank by drain pipeline ［ 11 ］ overflow.
The two-way servo-actuated plunger type grease lubrication pump of Fig. 2 is two lubricated pump housings in parallel, and its effect is identical.
The two-way servo-actuated plunger type grease lubrication pump of the utility model design by the corresponding selector valve of main hydraulic system alternately, import and export from left and right sides power oil, make power oil enter the pump housing, the lubricating grease exchange is sucked pumps, regularly fixed point exchange pressure lubrication, improve the life-span of lubricating component, also saved lubricating grease, improve lubricating efficiency.
