Product Description
The Introduction of Products
Automobile hand pump
SB02 hand oil pump and hydraulic emergency cut-off valve matching use, suitable for liquefied gas, natural gas, liquid ammonia and other dangerous gas storage and distribution station of large tanks or tank car emergency cut-off valve. Under the working condition, the performance of the pump can be used to control the opening or closing of the emergency cut-off valve.Description of working principle and structure 1. The hand pump through the handle do reciprocating motion, increase pressure to open the emergency shut-off valve, medium can be passed, in case of fire or other emergency, open the hand pump pressure relief valve, hydraulic system pressure quickly, make emergency cut-off valve shut down immediately, or when the temperature rises to more than 75 ºC, installed in the pump or emergency cut-off valve fusible plug melt immediately, To achieve automatic pressure relief wood, so that the emergency cut-off valve automatically and quickly closed.2. The main structure of the hand pump is the plunger of the suction oil, the oil inlet valve, the oil outlet valve and the pressure relief valve. The sealing space formed by the closing of the plunger and the oil inlet and outlet valve is the working chamber of the oil pump. When the volume of the working chamber increases from small to large due to the upward movement of the plunger, the pressure in the chamber is lower than the atmospheric pressure, the oil inlet valve opens, and the oil enters the working chamber through the oil filter valve. When the plunger moves down the volume of the working chamber from large to small, the oil pressure of the working chamber rises, the oil outlet valve is opened, and the pressure oil is discharged into the oil system for the emergency cut-off valve to open. The pressure relief valve is set for pressure relief of the pressure oil circuit system, the pressure relief valve should be closed when working, and the pressure relief valve should be opened when the oil circuit system needs pressure relief, that is, the emergency cut-off valve is closed.UseThe oil tank of the pump is in the outer body cavity of the pump, and the oil plug of the upper cover can be opened when the oil is filled. If the volume of the oil column is not enough, the auxiliary oil tank can be added.| Strength test | 10.0Mpa |

| The fault phenomenon | Reason | Elimination method |
| No pressure boost when pumping oil (oil pump does not absorb oil). | 1. The sealing surface of the oil inlet valve leaks oil.
2. Leakage when plunger presses oil.
3. Oil absorption filter is blocked. | 1. Overhaul the sealing surface, replace the gasket, and tighten the connector.
2. Repair the damage on the inner wall of the plunger and cylinder and replace the sealing ring.
3. Change the oil to clean the dirt in the filter screen. |
| After stopping the pump, the gauge pressure drops and the system leaks oil. | 1. The pressure relief valve is not closed or the sealing surface is damaged.
2. The sealing surface of the oil outlet valve is damaged or contaminated.
3. Leakage of emergency cut-off valve and oil line system or oil pipe press head. | 1. Tighten the pressure relief valve when repairing the sealing surface of the pressure relief valve and pump oil.
2. Overhaul the sealing surface, replace the sealing gasket, and remove dirt.
3. Repair emergency cut off and oil, oil pipe according to the head of the leakage point. |
Hand pump
Hand oil pump and emergency shut-off valve matching use, suitable for liquid ammonia, ammonia, liquefied petroleum gas storage and distribution station of large tank or tank car emergency shut-off valve in working state, using the performance of the pump to control the emergency shut-off valve opening or closing purpose.Product overview| Product model | SB03-175 |

The working principle of
1. Manual oil pump through the handle do reciprocating motion, increase pressure to open the emergency shut-off valve, medium can be passed, in case of fire disaster or other emergency, to the hand pump pressure relief valve opens, hydraulic system pressure quickly, make emergency cut-off valve Closed, or when the temperature to 75 ºC above, installed in the pump or emergency cut-off valve fusible plug melt immediately, To achieve automatic pressure relief wood, so that the emergency cut-off valve automatically and quickly closed.
2. The main structure of the hand pump is the plunger of suction oil, oil inlet valve, oil outlet valve and pressure relief valve. The sealing space formed by the closing of the plunger and the oil inlet and outlet valve is the working chamber of the oil pump. When the volume of the working chamber increases from small to large due to the upward movement of the plunger, the pressure in the chamber is lower than the atmospheric pressure, the oil inlet valve opens, and the oil enters the working chamber through the oil filter valve. When the plunger moves down the volume of the working chamber from large to small, the oil pressure of the working chamber rises, the oil outlet valve is opened, and the pressure oil is discharged into the oil pipeline system for the emergency cut-off valve to open.
3. The pressure relief valve is set for pressure relief of the pressure oil path system. The pressure relief valve needs to be closed when working, and the pressure relief valve needs to be opened in the oil path system, that is, the emergency cut-off valve is closed.
4. The oil tank of the pump is in the outer body cavity of the pump, and the oil plug on the cover can be opened when the oil is filled. If the volume of the oil column is not enough, the auxiliary oil tank can be added.

2. The pump should be cleaned before installation, check whether the tight thread of each part is loose. 3. During installation and use, remove the silk plug of the oil outlet hole, connect it with the pipeline of the pressure relief system, inject synthetic spindle oil, move the handle to inject pressure oil into the system, pay attention to the oil storage amount of the oil pump, if not enough, add refueling or install auxiliary oil tank.
4. After filling the oil, the pressure relief valve is closed, pressurized into the system, and then the pressure relief valve is opened, and repeated 3-5 times to eliminate the gas in the oil system and maintain the pressure stability.
5. When using the oil pressure of the high speed working chamber of the pressure regulating valve, the pressure regulating valve should be in the position of the valve disc open, and gradually increased from the low pressure to prevent the sudden increase of oil pressure from hitting or damaging the pressure gauge.
6. Limited to the small capacity of oil storage in the oil tank, when the oil pipeline system is long or a oil pump is used to control several emergency shut-off valves, the auxiliary oil tank needs to be added.
7. In order to prolong the service life of the oil pump, prevent the rise of the external ambient temperature, oil path inflation, damage to the emergency cut-off valve and manual oil pump, impact pressure gauge, it is necessary to check the equipment frequently.
8. Regularly clean the hand pump and oil pipeline, replace the synthetic lake oil, replace once a year.JUNKANG FLUID TECHONOLOGY CO., LTD
