Abstract
The invention relates to a water-cooling device for a three-cylinder plunger-pump oil box, which comprises a crankshaft-box body, wherein a rear cover is installed at one end of the box body, and the other end of the box body is connected with a cylinder body. The water-cooling device for the three-cylinder plunger-pump oil box is characterized in that a cooling water pipe is installed in the box body, a water inlet of the cooling water pipe is installed on the rear cover, and a water outlet of the cooling water pipe penetrates through the inner part of the cylinder cavity of the cylinder body or is still installed on the rear cover. In the scheme, the cooling water pipe is installed in the crankshaft-box body for reducing the temperature of lubricating oil in the three-cylinder plunger-pump oil box, no precedent exists, the oil temperature of the oil box during working is markedly reduced after the technical scheme is adopted, the oil temperature is kept within the normal range of a design standard through continuous working, and remarkable effects are obtained.
Description
Technical field
The present invention relates to three-cylinder plunger pump, particularly relate to the water-cooling apparatus of three-cylinder plunger pump fuel tank (crankcase).
Background technique
Three-cylinder plunger pump is widely used in fire-fighting truck, high building send cooperating equipments such as water, mine dedusting washup, oil field supercharging and washing machine.Three-cylinder plunger pump has a fuel tank, and transmission paries such as bent axle, connecting rod and plunger are immersed in the fuel tank and are lubricated (so fuel tank just crankcase), and transmission part when work mutually between constantly friction can produce heat; These heats pass to lubricant oil again, the oil temperature in the fuel tank are constantly raise, according to the performance of lubricant oil; To the designing requirement of three-cylinder plunger pump, the oily temperature in the fuel tank allows to raise at normal temperatures 35 ℃, if the oil temperature is in case surpass this standard; Oil viscosity can reduce, and causes the friction factor between each kinematic pair to increase Sealing performance change, inefficacy; Cause parts to damage, for example bent axle, connecting rod are killed, and seriously influence the working life of pump.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, the temperature of lubricant oil in a kind of effective reduction fuel tank is provided, prevent that oil viscosity from reducing, avoid damaging the water-cooling apparatus of the three-cylinder plunger pump fuel tank of the relevant component of machine.
The technological scheme of the water-cooling apparatus of three-cylinder plunger pump fuel tank of the present invention is: comprise crankcase body; One of casing bonnet is installed; The other end of casing connects cylinder block; It is characterized in that water-cooling tube is installed in the described casing, the water intake of water-cooling tube is installed on the bonnet, perhaps still is installed on the bonnet in the cylinder chamber of the straight-through cylinder body of the water outlet of water-cooling tube.
The invention discloses a kind of water-cooling apparatus of three-cylinder plunger pump fuel tank, described fuel tank is exactly a crankcase, one of crankcase body bonnet is installed; The other end of casing connects the cylinder block of pump, and major character is water-cooling tube is installed in the described casing, and the connection pattern of water-cooling tube can have two kinds; A kind of water intake of pattern water-cooling tube gets at bonnet; Water-cooling tube directly is opened in the cylinder block cylinder chamber of pump after in the casing, is pressurized to high pressure water through plunger in the cylinder chamber and sees off, and the water-cooling tube radical of this pattern is not limit; Be generally two, but also can be one or three.The water-cooling tube water intake of another kind of pattern is at bonnet, and water outlet is also at bonnet, and the water outlet of water-cooling tube is connected the water intake of pump by pipe, and the water-cooling tube of this pattern is generally two or four, in casing, is welded into the U font.This programme is installed water-cooling tube in crankcase body; Lubricant oil in the three-cylinder plunger pump fuel tank is lowered the temperature, beyond example, through after the present technique scheme when work fuel tank oily temperature drop obviously low; Continuous operation makes oily temperature remain on the normal range (NR) of design standard, has obtained significant effect.
The water-cooling apparatus of three-cylinder plunger pump fuel tank of the present invention comprises crankcase body, one of casing bonnet is installed, and the other end of casing connects cylinder block, it is characterized in that described casing top is the crankcase fuel tank, and the bottom of casing is a cooling water chamber.This programme is separated into crankcase fuel tank and cooling water chamber two-part with casing; Adorn lubricant oil in the crankcase fuel tank; Adorn cooling water in the cooling water chamber, the cooling water in the cooling water chamber is lowered the temperature to the lubricant oil in the crankcase fuel tank, has obtained beyond thought effect equally.
