Abstract

The utility model relates to a cooling water system for a hot lean oil pump. The cooling water system comprises an oil pump, an oil inlet pipe, an oil outlet pipe, a cooling water inlet pipe and a cooling water outlet pipe, wherein the oil inlet pipe and the oil outlet pipe are arranged on the oil pump, the cooling water inlet pipe and the cooling water outlet pipe are arranged on the oil pump, a check valve is also arranged on the water inlet pipe, two sides of the check valve are respectively provided with diameter changing joints, and the check valve is arranged on the cooling water inlet pipe through the two diameter changing joints. In order to prevent wash oil from entering the cooling water system, the check valve is arranged at an inlet part of a cooling water pipeline, so when the cooling water pressure is smaller than 0.35MPa, medium wash oil in the lean oil pump cannot enter the water system, and the water pollution phenomenon is avoided. In order that the check valve can be matched with the cooling water pipeline of the hot lean oil pump, two sides of the check valve are provided with two kinds of diameter changing joints, and the check valve can be conveniently and fast arranged on the cooling water pipeline of the hot lean oil pump through the diameter changing joints.

Description

The oil-poor oil pump cooling water system of heat
Technical field
The utility model relates to a kind of oil pump, relates in particular to a kind of hot oil-poor pump that is applied in the oil-poor course of conveying of coal tar enterprise heat.
Background technique
Hot oil pump all is provided with the mechanical seal cooling water, and water is got into by intake pipe in the mechanical seal of hot oil pump again from spill laggard bilge well from mechanical seal.For the oil-poor hot oil pump of using of coal tar enterprise heat, generally adopt the big double mechanical seal of anti-type chemical industry hot oil pump, 110 meters of lifts, the machine sealing chamber internal pressure is very big, needs the cooling water of relevant pressure to come balancing machine envelope internal pressure.According to technological requirement, cooling water pressure is just about 0.35MPa, and when hydraulic pressure during less than 0.350.35MPa, the medium washing oil will get into water system in the hot oil-poor pump, causes water to pollute.Bring to sewage treatment.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency provides a kind of heat oil-poor oil pump cooling water system.
The purpose of the utility model realizes through following technological scheme:
The oil-poor oil pump cooling water system of a kind of heat comprises oil pump, is arranged on oil inlet pipe and oil outlet tube on the oil pump, is arranged on cooling water inlet pipe and outlet pipe on the oil pump, on intake pipe, also is provided with safety check.
Above-mentioned oil-poor oil pump cooling water system, the safety check both sides are provided with reducer union, and safety check is arranged on the cooling water inlet pipe through these two reducer unions.
Adopt technique scheme; The utility model has following advantage: get into cooling water system in order to prevent washing oil; In cooling water pipeline inlet safety check is installed; Even like this at cooling water pressure during less than 0.350.35MPa, the medium washing oil can not get into water system yet in the hot oil-poor pump, has stopped the phenomenon that water pollutes.For the cooling water pipeline that makes safety check and hot oil-poor pump matches, on the both sides of safety check two kinds of reducer unions are set, can easily and fast safety check be installed on the cooling water pipeline of hot oil-poor pump through reducer union.The utility model is simple in structure, and cost is low, only comes yuan just can solve the technology that medium washing oil entering water system causes water to pollute in the cooling water pressure hour hot oil-poor pump with ten and produces problem, bring the big economic benefit of tool to enterprise.
Description of drawings
Fig. 1 is the structural representation of hot oil pump.
Fig. 2 is the structural representation of the utility model.
Embodiment
The oil-poor oil pump cooling water system of a kind of heat as shown in Figure 2 comprises oil pump 2, is arranged on oil inlet pipe 6 and oil outlet tube 1 on the oil pump 2, is arranged on cooling water inlet pipe 3 and outlet pipe 6 on the oil pump, on intake pipe 6, also is provided with safety check 5.Because the safety check on the market is generally bigger; And the cooling water pipeline of hot oil-poor pump has only DN10; Need design, make two kinds of reducer unions, therefore be provided with reducer union 7,8 in the safety check both sides, a kind of is DN25-M20; Another kind of DN25-ZG3/4, safety check is connected on the cooling water inlet pipe 3 through these two reducer unions.
