Abstract
The utility model provides a mechanical pump sealing oil injection system. The mechanical pump sealing oil injection system comprises a manual valve at a sealing oil inlet end, and a manual valve at a sealing oil outlet end, wherein a flow limiting pore plate and a check valve are arranged between the manual valves, the check valve is arranged below the flow limiting pore plate, and a filter is arranged between the upper portion of the flow limiting pore plate and the manual valve at the sealing oil inlet end. Due to the fact that the flow limiting pore plate is added, the flow and pressure situation after the pore plate is improved, flow and pressure stability after the pore plate is ensured, and fluctuation is reduced; meanwhile, the appropriate pore plate is selected according to the needed flow and the pressure to ensure the oil sealing effect, and the amount of redundant sealing oil is reduced to some extent; due to the fact that the check valve is put into use, the sealing oil backflow phenomenon caused by sealing leakage is avoided.
Description
Technical field
The utility model relates to sealing oil system field, specifically a kind of pump oil sealing injected system.
Background technique
Part oil refining and chemical plant installations are less because of high temperature pump, and pump oil sealing is without special oil sealing injected system, and oil sealing injection amount is difficult to control, and unstable, easily causes the waste of oil sealing.
Present stage oil sealing is injected and is depended merely on a DN20 valve regulated, is difficult for regulating, and easily seals in sealing oil system when pump seal leakage and result in blockage.
Model utility content
The utility model, in order to solve the problem of prior art, provides one can stablize oil sealing, and the pump oil sealing injected system that can not result in blockage.
A kind of pump oil sealing injected system described in the utility model, comprise the manually operated valve of oil sealing entry end and the manually operated valve of oil sealing outlet end, it is characterized in that: between manually operated valve, be provided with restriction orifice and safety check, safety check is located at the below of restriction orifice, between the top of restriction orifice and the manually operated valve of oil sealing entry end, is provided with filter.
Further improve, described filter is y-type filter, wherein in y-type filter, is provided with steel wire.
The utility model beneficial effect is:
1, adding of restriction orifice, improve flow and pressure condition after orifice plate, thereby ensure the stability of flow and pressure after orifice plate, reduce fluctuation, select suitable orifice plate according to the size of required flow and pressure, ensure oil sealing effect, and reduce to a certain extent unnecessary oil sealing amount simultaneously.
2, coming into operation of safety check stops the generation that causes oil sealing refluence phenomenon because of seal leakage, is difficult for resulting in blockage.
3, the application of filter, filters the impurity in oil sealing, ensures the purity of oil sealing.
4, this technique is automatically to regulate, without manual operation.Less investment, maintenance cost is low, and can significantly reduce cost of use, saves oil sealing amount.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure: 1. restriction orifice; 2. safety check; 3. manually operated valve; 4. filter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of pump oil sealing injection device, comprise the manually operated valve 3 of oil sealing entry end and the manually operated valve 3 of oil sealing outlet end, between manually operated valve 3, be provided with restriction orifice 1 and safety check 2, safety check 2 is located at the below of restriction orifice 1, between the top of restriction orifice 1 and the manually operated valve 3 of oil sealing entry end, is provided with filter 4.Described filter 4 is y-type filter, wherein in y-type filter, is provided with steel wire.
The utility model working principle is: the adding of restriction orifice, improve flow and pressure condition after orifice plate, thereby the stability of flow and pressure after guarantee orifice plate, reduce fluctuation, select suitable orifice plate according to the size of required flow and pressure simultaneously, ensure oil sealing effect, and reduce to a certain extent unnecessary oil sealing amount; Coming into operation of safety check stops the generation that causes oil sealing refluence phenomenon because of seal leakage.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
