Abstract
The utility model relates to a multi-function high-pressure reciprocative pump, which comprises a prime motor, a shaft coupling, a crank case, a pressure cylinder body, and water collector. The prime motor is directly connected with a crank shaft via the shaft coupling. A water cooling channel is annularly arranged between the outer wall of the crank case and a pump housing, and the outlet of the water cooling channel is connected with a water inlet of the pressure cylinder. A seal pair of a plunger is connected with an externally connected tightly regulated screw plug, and a pressing sleeve of the tightly regulated screw plug is tightly pressed on the seal pair of the plunger. The utility model can reduce the temperature of the lubricating oil in the crank case and can regulate tightly the plunger sealing under the condition of no stop.
Description
The utility model relates to a kind of multifunctional high pressure reciprocating pump.
Existing three cylinder high pressure reciprocating pumps generally are made up of prime mover, speed reducer, crankcase, pressure cylinder, the body that catchments.Between motor and bent axle, adopt the speed reducer gearing down.And said structure complex structure not only again because component are more, makes pump housing heaviness itself, and transmission efficiency is low.If speed reducer is not installed, then the pump plunger reciprocal time can improve greatly, and transmission efficiency also can correspondingly improve.But and the need solution is the cooling of lubricant oil in the crankcase and the wearing and tearing of plunger seal.
The purpose of this utility model aims to provide a kind of lubricating oil temperature in the crankcase that reduces, and reaches under non-stop-machine situation plunger is sealed into the multifunctional high pressure reciprocating pump that row tightens.
The purpose of this utility model purport realizes by following manner:
The utility model comprises prime mover, coupling, crankcase, pressure cylinder, water-collecting machine, prime mover directly is connected with bent axle by coupling, between crankcase outer wall and pump case, be equipped with cooling water passage, the outlet of cooling water passage is connected with the water intake of pressure cylinder, the sealing pair of plunger is connected with the external plug screw that tightens, and the gland that tightens plug screw presses on the plunger seal pair.
Described prime mover can be motor or diesel engine.
Identical at pressure, and do not change under the situation of plunger size, increase when being twice flow, original machine power is increased simultaneously relatively, only need on bent axle, set up three secondary crankshaft connecting rods, correspondingly increase in the crankcase another side and adorn a pressure cylinder and just can.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is a plan view of the present utility model;
Accompanying drawing 2 is a plan view of the present utility model;
Accompanying drawing 3 is a left view of the present utility model;
Accompanying drawing 4 is the structural representation of the utility model water-collecting machine.
Shown in accompanying drawing 1,2,3, the utility model comprises motor 1, coupling 2, bent axle 3, crankshaft linkage 4, engine housing 5, pressure cylinder 6, plunger 7, plunger seal pair 8, the long guide pin bushing 9 of beryllium bronze, tightens plug screw 10, feed liquor valve 11, liquid discharging valve 12, pumps working joint 13, water-collecting machine 19, crankcase 20, cooling water passage 21 that the mouth of a river connects.Motor 1 directly is connected with bent axle 3 by coupling 2, outer wall at crankcase 20, on the engine housing 5 around being drilled with cooling water passage 21, the water intake of cooling water passage 21 be external in engine housing 5 water supply connectors and be connected, water outlet is communicated with pressure cylinder 6, and the water inlet of pump is by cooling water passage 21 ability feed pressure cylinders 6, again by feed liquor valve 11 and liquid discharging valve 12, arrive delivery side of pump water and connect working joint 13, water-collecting machine 19 is connected with the working joint 13 that pumps mouth of a river connection.Water-collecting machine 19 comprises pressure maintaining valve 14, safety valve 15, pressure gauge extension bar 16, pressure release valve, water outlet working joint.The sealing pair 8 of plunger with external with tighten plug screw 10 and be connected, the gland 22 that tightens plug screw 10 presses on the dried plunger seal pair 8, plunger 7 inserts in pressure cylinders 6 stuffing box glands by plunger seal pair 8 by engine housing 5, keeps sealing.More than pressure 30MP; then need increase the long guide pin bushing 9 of beryllium bronze and form combination seal; produce when leaking in secondary 8 heavy wears of plunger seal in the work; can need tighten plug screw 10 only not shutting down then; make to tighten plug screw 10 and further press on plunger seal pair 8, to remedy the part that is worn by gland 22.
The utility model is because simple in structure, and volume reduces, and transmission efficiency improves.Lubricant oil in the crankcase then can cool off by the cooling water passage around the crankcase in pump housing water inlet itself.When the seal arrangement worn piston, also can under not shutdown situation, tighten sealing, reduce cost, increase the benefit.
The utility model is applied widely, can make hydraulic test pump, high pressure water-injection pump, conveying industrial chemicals pump, oil transfer pump, boiler feed pump, be the high-pressure service pump of medium with water, the usefulness such as washery pump of homogeneous high-pressure service pump.
